First Beta Release on Lollipop BioShock
Alright guys, I have shaped this mod up to the best of my abilities and I present to you the Bravo version of it. I will get other kernel versions of this mod out but in the mean time I am sticking with the Original work space one based off of the Lollipop BioShock 3.10.40. I know this is the older version, but I will mass update ALL the kernels really soon. Basically everything (even the app) are enclosed into 1 ZIP file so all you have to do is flash the Kernel and you are ready to go. A couple of things I would like to get out there:
1. You should have a Fully charged ZL Battery. I wouldn't say before flashing this as you can re-calibrate the app, but I would recommend that you do so to avoid any confusion.
2. When you charge the battery with this mod, yes the percentage does charge fast and it will most likely show 100% BEFORE the battery reaches 100%. There is a issue with the current/mA flow readings IN the app and that will be fixed in the near future. Please understand that TRUE 100% is when the phone says "Fully Charged 100%, Unplug Charger" not when the Fuel gauge (next to the clock) says 100%.
3. Some people ask "Will the app Accurately calculate the battery to avoid shutting down at lets say 15% or still running 1% for days like normal"? And the answer to that is most likely Yes, and Possibly no. I say yes to the first part because you can put in the different drain values of each component in the Note 4 so that the app can detect the draining and calculate accordingly. Now, I will warn you that I have never used this mod to do a full complete drain. So I will say I wouldn't recommend letting the battery go all the way down to 15% (just as a safety net if you plan on going out, etc) in-case the battery does hit 3.4 volts which is the Note 4's 0% Shutdown target. And the 1% mod is almost unlikely.
4. Finally, I have received your messages and Emotion Kernel seems to be the popular Kernel at this time (I will be using it in the coming days also) so I will get to that next once I get the source code loaded. (KitKat users, you are not forgotten) I will also be posting the Kernel files so that Kernel devs can make different variants once I hear from you guys on how this mod is working. To me, I think its great. From the way it was before I can say its a Improvement from the drain calculation side. The charging side needs work, but hey, you hardly have to charge the dang thing anyways lol.
Now to the Installation
Of course, I would recommend that you do a backup of course and that you have a backup kernel with you. Basically, if you can use this kernel http://forum.xda-developers.com/note...-2014-t2962744 It should work.
Once you have flashed the file below "BioShock_N910T_TW_LP_Extended_Battery_Mod_OFFICIA L_BRAVO.zip", you should also wipe delvik and cache just to make sure everything goes smoothly. If the mod was successfully installed, your battery level should read "101%". It will read 101% every time you reboot just to keep things clean and then go back to the App's fuel gauge level 1 minute after boot.
If it shows 101%, go into your Apps and you should see a App called "Fuel Gauge Extended..." Open that app up and wait about 3-5 seconds for everything to populate (Done to keep battery usage down). Make sure to check Start on Boot if you want the service to start with the phone (which I think EVERYONE should do) and then tap start monitor. You might get a SuperSU permission screen which you want to grant permissions to. Once you see the Status saying "Running" go down to the debug area to the "Patch Status" string and it should report "ok/[success]]" and your real battery gauge should read whatever the Software Status says.
This app also doesn't have the on screen dedicated 3-dot menu buttons so you have to go old fashioned and how down the left menu soft-key for a second until a menu pops up at the bottom which shoes Start Full Charge, Set full battery, and configuration. This is where you can calibrate your battery so that once you fully charged your battery, you go into the app and select "Set full battery" to set the app and battery capacity to 100%. Please note that this will take anywhere from 30 seconds to 1 minute to update the battery meter globally. You don't want to press either one of these when you already have calibrated the battery before and you are at half a charge as you will lose your capacity remaining level and accuracy until you fully charge again.
Under configuration, you can make the app calibrate to 100% every time your phone displays "Fully charged, disconnect charger". You can also disable the notification under Notification Icon.
Hardware current is where you can change the different consumption values of each component. I wouldn't mess around here too much as you could create a imbalance within the app calculations.
And basically that's pretty much it. IF and SHOULD you have any problems, just reply here or shoot me a PM and I will help you to the best of my abilities.
Thank you guys for your patience and I hope you enjoy this beta mod.
About the values that you input, this would lead to inconsistencies wouldn't it? Like how would we be able to know the exact values? Is it possible to use the values in the Fuel Gage chip?
e.g. It still says there is charge in the battery, but there is none, and the phone just switches off in the middle of use?

While this maybe true, you also have to take into consideration that the battery already does this without this mod when it stays at 1% for extended periods of time. Also, there is a file in the framework-res.apk that has all the power profiles of each component in its mAH values. But I am pretty sure with this mod, I wouldn't think you would drain the battery all the way to 2 or 5% expecting to go another day or to go to work with it. When you get down to 5%, the screen dims automatically so that alone would force people to charge the phone. But that is a good question. Now the ONLY Time the percent values would be off is when you use the phone in recovery mode for extended periods of time or when you charge the phone when the phone is off, you have to go into the app and reset to 100%. I am working on a code which makes the percent automatically go to 100% when voltages hit fully charged.

So we don't have to find values? Is that how the Fuel Gage chip does it? How confident are you in how accurate this will be?

The fuel chip uses voltage levels as well as values stored in the kernel to come up with a near accurate reading. What I can do is put the stock battery in and set the app to the stock capacity and see if the app capacity matches up with the Fuel gauge capacity. But I am pretty confident that it will be accurate. Again, even if we get to 5 or 3% battery before shut down, its MUCH better than getting to 1% and still have 55% battery left. And that can be fixed.
The app can tell the different brightness levels from 0 to 255, Rather bluetooth, wifi, gps is on or off, talking on phone, etc. and it auto adjusts accordingly.

Alright no problem. I didn't release anything yet until I make sure everything is super stable.
I'm waiting for the release
I had to delay releasing the beta because I found a major issue with the current polling fix which shut down charging prematurely because it didn't poll any Temperature and Voltage levels form the Thermistors. But I have found the string I was looking for all along and I will begin going the back door way. Once I can get that done, I will have no problem releasing the beta for testing. Before I officially post it on here, I want to give it to a select people first to let them try it out and report back to me any issues they encounter so if you are interested in Testing it, please send me a PM. I have a couple of people already down. ALSO, Please put down what kernel you are using, The Source Code link of the kernel and the Variant of your Note 4. I am working with the BioShock Kernel right now and I am planning to do a Emotion version as well. For those who are on AOSP or AOKP kernels / ROMS shoot me a PM and I can see what I can do. Once again, I want to thank you guys for your continued patience.
One more thing, It also helps to charge your ZL Battery all the way to 100%
Congrats! Persistence pays off.
Emotion kernel for me
I finally got the polling redirected so that the phone still reads the Temp, Voltage, Current, and other values which makes sure that the battery remains safe. Only the calculated capacity from the App will go through the system. I could release it right now, but I want to fix one more value before it passes me.
Running more test before I pass it on to some of you guys for your testing. I have the Temperature, Current and Voltage sensors working now I just need to make the current percent value stick with the file so when I do a restart, it doesn't jump up.

Awesome work man, I look forward to using this. On lollipop it seems my zL runs about a 15% battery difference from actual to estimated. This would be of great help.

Ah, I have yet to test the mod. Have to do a backup first because I'm not too sure bioshock will run Verizon without complications. I haven't tried any other kernels running Jasminerom with kexec.

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.
I got an replacement due to my phone beyond repair.
I'm running original stock firmware, of-course rooted. Since the replacement I'm trying to get my phone to full charge but it doesn't and also I notice that the charging is quite slow.
I installed "Battery Monitor Widget" to see how much power it is drawing and found that AC power draws only about 350+mA and sometimes it is as low as 8mA. (Some times it draws about 750+mA). I notice that the temperature also reaches somewhere about 45 to 48 degree.
Once it reaches about 90% or so, it starts to drain battery instead of charing it.
I find it quite abnormal. Anyone with this kind of problem and found an solution?
Thanks in advance for the replies and suggestions.
What I'd sudjest is updating your phone through seus or PC companion or if your an American at & t user update to a newer firmware through the flash tool (you can find I link to it through my signiture) or if you can't update try and use the repair option through seus or PC compainion.

I did that yesterday. I repaired the firmware and reloaded all the application one by one from scratch. The only thing I restored is contacts so that I could eliminate all the other factors which can cause this issue.

Good idea. I will try that as well as try to do a clean wipe and just try to charge with nothing loaded in. That will give a better idea where the problem is.
Thanks for the great tip, I will update you tomorrow.
Had that happen before, I had to remove sim card and let it drain out slowly for a week, then charge. Problem solved
I think I had similar problem, except that my processor went on full load when its almost fully charged causing it to drain the battery instead. Still lookin for answer to that, will wiping battery stats help?
I reset my phone to factory and did a re-flashing again using SEUS and I tried it charging immediately without loading any application (only loaded Battery Monitor Widget from Market to see the battery temperature and mA units drawn) and wow, it charged like a normal X10. So I guess it has something to do with whatever I loaded or modded it with.
I'm trying to find it out. Later tonight I will try to load all the application one-by-one and try again to charge to see whether I can isolate it.
During this process, I did takeout my SIM card for a period of 1 hour or so, so not sure whether that did the trick (If that's the case, thanks to gogogu)
In the meantime, I have a strong feeling it would be due to the flashtool and new recovery, but again there isn't any proof. I suspect this because this is the new thing I did compared to my old phone.
Any thoughts are welcome.

I don't have issues with processor. It works at full throttle when it supposed to work and then goes back to normal.
Hrmmm alright, but if you ever had the draining issue while charging and the battery temp rises up again. Check the CPU usage just incase
After yesterday's event, seems like stable (I did face the same issue once). Not sure which cured it and currently monitoring...
EDIT: Back to square one. The issue started again and the battery refues to fully charge! I'm going mad
Finally given up, sent for service and came back after 5 days of repair.
Repair Notes: No problem found !!!
But today morning I tried to charge and it's the same issue . Makes me go mad. Really, I don't know what to do!

I too have exactly the same problem with my x10i.....
tried everything like rooting, using stock & custom ROMs, etc... still problem persist ...
while charging , power goes from 900mA to 200mA or lower, & doesn't reach 100% full...
i use current widget from market to read the power values ....
please help me friends .... to resolve my problem ...
Thanks a lot...
Makzer.

hello mates...
please reply to my problem dear friends ..
looking forward ...

I got an replacement due to my phone beyond repair.
I'm running original stock firmware, of-course rooted. Since the replacement I'm trying to get my phone to full charge but it doesn't and also I notice that the charging is quite slow.
I installed "Battery Monitor Widget" to see how much power it is drawing and found that AC power draws only about 350+mA and sometimes it is as low as 8mA. (Some times it draws about 750+mA). I notice that the temperature also reaches somewhere about 45 to 48 degree.
Once it reaches about 90% or so, it starts to drain battery instead of charing it.
I find it quite abnormal. Anyone with this kind of problem and found an solution?
Thanks in advance for the replies and suggestions.

What program do you use to check your battery temperature. I rememeber there was one that wass bettery draining. The same is also possible with battery level monitor

I realize that much of this is common knowledge on XDA. Still, every day I see people post about how their phone "loses" 10% as soon as it comes off the charger. I also have friends who can't understand why their battery drains so quickly. Trying to explain this to people without hard numbers is often met with doubt, so I figured that I'd actually plot it out with real data.
So it's not a piece that is optimized for this audience, but I hope that you find it interesting.

Your Smartphone is Lying to You
(and it's not such a bad thing)
Climbing out of bed, about to start your day, you unplug your new smartphone from its wall charger and quickly check your email. You've left it plugged in overnight, and the battery gauge shows 100%. After a quick shower, you remember that you forgot to send your client a file last night. You pick up your phone again, but the battery gauge now reads 90%. A 10% drop in 10 minutes? The phone must be defective, right?
A common complaint about today's smartphones is their short battery life compared to older cell phones. Years ago, if you accidentally left your charger at home, your phone could still make it through a weeklong vacation with life to spare (I did it more than once). With the newest phones on the market, you might be lucky enough to make it through a weekend.
And why should we expect anything else? Phones used to have a very short list of features: make and receive phone calls. Today we use them for email, web surfing, GPS navigation, photos, video, games, and a host of other tasks. They used to sport tiny displays, while we now have giant touch screens with bright and vibrant colors. All of these features come at a cost: large energy requirements.
Interestingly enough, improvements in battery management technology have compounded the average user's perception of this problem. Older phones were rather inelegant in their charging behavior; usually filling the battery to capacity and then switching to a trickle current to maintain the highest charge possible. This offered the highest usage time in the short-term, but was damaging the battery over the course of ownership. As explained at Battery University, "The time at which the battery stays at [maximum charge] should be as short as possible. Prolonged high voltage promotes corrosion, especially at elevated temperatures."[1]
This is why many new phones will "lose" up to 10% within a few minutes of coming off the charger. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 90%. Leaving the phone plugged in overnight does not make a difference: the phone only uses the wall current to maintain a partial charge state.
To monitor this, I installed CurrentWidget on my HTC ADR6300 (Droid Incredible), an app that can log how much electric current is being drawn from the battery or received from the charger. Setting it to record log entries every 10 seconds, I have collected a few days worth of data. While many variables are involved (phone hardware, ROM, kernel, etc) and no two devices will perform exactly the same, the trends that I will describe are becoming more common in new phones. This is not just isolated to a single platform or a single manufacturer.
Chart 1 shows system reported battery levels over the course of one night, with the phone plugged in to a charger. Notice that as the battery level approaches 100%, the charging current gradually decreases. After a full charge is reached, wall current is cut completely, with the phone switching back to the battery for all of its power. It isn't until about two hours later that you can see the phone starts receiving wall current again, and even then it is only in brief bursts.
The steep drop in reported battery seen past the 6.5 hour mark shows the phone being unplugged. While the current draw does increase at this point (since the phone is being used), it still cannot account for the reported 6% depletion in 3 minutes. It should also be obvious that maintaining a 100% charge state is impossible given the long spans in which the phone is only operating on battery power.
Using the data from CurrentWidget, however, it is quite easy to project the actual battery state. Starting with the assumption that the first battery percentage reading is accurate, each subsequent point is calculated based on mA draw and time. Chart 2 includes this projection.
Now we can see that the 6% drop after unplugging is simply the battery gauge catching up with reality.
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge
Option one has clearly fallen out of favor as it prematurely wears devices. Option two, while being honest, would most likely be met with many complaints. After all, how many people want to see their phone draining down to 90% while it is still plugged in? Option three therefore offers an odd compromise. Maybe phone companies think that users will be less likely to worry about a quick drop off the charger than they will worry about a "defective" charger that doesn't keep their phone at 100% while plugged in.
Bump It. Or Should You?
One technique that has gained popularity in the user community is "bump charging." To bump charge a device, turn it off completely, and plug it into a charger. Wait until the indicator light shows a full charge (on the ADR6300, for example, the charging LED changes from amber to green) but do not yet turn the device back on. Instead, disconnect and immediately reconnect the power cord. The device will now accept more charge before saying it is full. This disconnect/reconnect process can be repeated multiple times, each time squeezing just a little bit more into the battery. Does it work?
The following chart plots battery depletion after the device has received a hefty bump charge (6 cycles) and then turned on to use battery power. Note that the system does not show the battery dropping from 100% until well over an hour of unplugged use, at which point it starts to steadily decline. Again, however, it should be obvious that the battery gauge is not syncing up with reality. How could the rate of depletion be increasing over the first 5 hours while the rate of current draw is relatively steady? And why does the projected battery line separate from the reported levels, but then exactly mirror the later rises and falls?
The answer, of course, is that bump charging definitely works. Rather than anchoring our projected values to the first data point of 100%, what happens if we anchor against a later point in the plot?
Aligning the data suggests that a heavy bump charge increases initial capacity by approximately 15%. Note that the only other time that the lines separate in this graph was once again when the phone was put on the charger and topped up to 100%. Just as with the first set of graphs, the phone kept reporting 100% until it was unplugged, dropped rapidly, and again caught up with our projections.
So what does it all mean?
If you absolutely need the highest capacity on a device like this, you will need to bump charge. There are currently people experimenting with "fixes" for this, but I have yet to see one that works. Be warned, however, that repeated bump charging will wear your battery faster and begin to reduce its capacity. If you are a "power user" who will buy a new battery a few months from now anyway, this presumably isn't a concern. If you are an average consumer who uses a device for a few years, I would recommend that you stay away from bump charging. The bottom line is that you don't really "need" to do it unless you are actually depleting your battery to 0% on a regular basis.
If you are someone who can top off your phone on a regular basis, do it. Plug it in when you're at home. Plug it in when you're at your desk. As explained by Battery University, "Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory."[2]
Beyond that, the best advice I can offer is to stop paying such close attention to your battery gauge and to just use your phone. Charge it whenever you can, and then stop obsessing over the exact numbers. If you really need more usage time, buy an extended-capacity battery and use it normally.

Wiping Battery Stats is Pointless, Says Google Jan 13 2012 09:30 PM | Ashley Glenn in Articles
Over time wiping battery stats has become a regular ritual among the Android enthusiast community. Buy a new battery? Wipe your battery stats! Upgrade to a bigger battery? Wipe your battery stats! Change kernels or restore a nandroid backup? You know what to do: wipe battery stats! But this ritual may soon become a thing of the past thanks to Google engineer Dianne Hackborn, who sheds a light on the subject that puts the tightly-held practice of wiping battery stats in the same league as carrying a lucky rabbit's foot or throwing a pinch of spilled salt over your shoulder.
Recommending that users wipe their battery stats appears in so many places and as a cure for so many ills that it has become ubiquitous. Adherents to this practice will sit and wait for their phones to report a full charge, then use an app that deletes the batterystats.bin file or reboot into recovery mode and wipe it from there. This supposedly cures a number of ills such as battery scaling issues, poor battery percentage reporting, and any of a myriad other number of issues. The truth is, according to Android Framework Engineer Dianne Hackborn, that this file is a repository for information about system activity and that it actually takes care of itself without the need for user intervention. From Dianne's post:
Quote
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.
It really can't be put more straightforward than that, folks. So rest assured next time you put a new battery in or flash a new kernel or restore an old backup that all you have to do to help your phone or tablet play nice with its battery is charge it to 100% and do nothing else. It really is that simple. But don't worry, enthusiasts - you'll find plenty of other reasons to hang out in recovery anyway.

Not wasting time flashing countless roms. Just wasting time wiping battery stats. That's the way it looks to me. Personally, I've always thought wiping battery stats was nothing but a whole lot of voodoo. Never had the need for it, don't see why anybody else would either. Let the flames begin.
I knew it couldn't possibly have an effect on actual battery life, but I thought maybe the file collected information about the length of the battery to calibrate the meter (because let's face it, with the X2 battery bug it's pretty clear that it doesn't get the value directly from the battery).
Funny thing about calibrating when it gets to 100 though...if there truly is something wrong with the meter, why would you suddenly trust it to know when it's charged? This is why I'd always charge it for a little extra and go by the voltage meter.
So basically, I've seen a couple of different readings. I've always waited past 100% and in different ROMs I've seen 4192, 4196, 4198, & 4200 mah.
I use the extended battery, sooooo readings may vary between regular battery.

I have an extended battery as well. Actually, I have two extended batteries and two regular batteries. Got the first one with my droid X, then a faulty extended battery (bad batch where the meter doesn't read right), then a replacement extended battery, then the one that came with my X2. No two are the same, but they should all max out near 4200 mV.
Edit: I use one extended battery.
Ok this screen is after install of CM 7 tonight, it reads 4205 mah, so why is it different, with different Roms?
Weird isn't it?

The stats can easily drift if you don't flash ROMs with your phone at 100% battery, hence why sometimes the calibration is needed [be sure to wipe stats when at 100% [either via app or recovery], best thing to do is fully discharge battery until auto off occurs and then fully charge with AC Wall Adapter and charge only screen, then when it hits 100% wait a few min, restart to OS to be sure it also says 100% [if not wait until it does and wait about 20 min longer] then restart to recovery and flash away [you could also wipe battery stats as part of flash if you do as stated before flashing]. I usually set it up so I fully discharge the phone [restarting to be sure a couple to few times] and then charge with phone off and charge only screen overnight and flash my ROM first thing in the morning right before I unplug it and unplug once I reach the point I am ready to restart device and do initial boot after flashing. Further details below...
Basically charge to 100% [or as absolutely close as you can get it [AC Wall charger is best unless you REALLY are forced to do it via USB and is best to charge via the charge only screen [phone is powered off and not booted in to the OS and all you normally see is just a battery filling on screen [and is fastest way to charge battery]]. Wait an additional 20 - 30 min after it registers 100% [this is to be sure the battery is absolutely topped off essentially] and I will generally do a restart as sometimes the battery may come back to less than 100% on a restart if your phone is not judging the battery right and is in need of calibration. If it does not register after restart wait until it hits 100% and wait the additional 20 min [you can cut out the initial 20 min wait if you want to do the restart to verify just wait the 20 min once you feel sure battery is as topped off as you can get it], then after wiping restart from recovery and unplug. Now be sure to drain the battery until auto shutoff [either stream media if in a hurry or through general usage. Either way wait until auto shut off.]. I usually will power the device back on and be sure it is not going to get back to the OS [if it even gets to boot logo I wait a few seconds and power it on again to be sure all I get is the boot vibrate on my device [some don't have this, but usually it's tablets almost all phones [and definitely both Motorola and Samsung do this]. I then charge it to full [again AC wall charger recommended as above and again with charge only, but as stated if you cant live with phone off or whatever you can do it with OS running as well. You are free to go as you wish after this second full charge really though if you do a couple more [dont have to be insane] it can help ensure the statistics get a good start.
As I believe I stated above the best way to avoid calibration as long as possible is to charge phone to 100% via phone off screen [with AC Adapter and wait the extra 20 min after it registers full before you flash [I will sometimes take it a step further, leave it plugged in while flashing my install zips and then once I go to restart system for the initial boot after ROM flash I will unplug the charger from the phone.
Hope this helps
Hey guys,
How much battery life do you get on your X2?
I just installed CM7 and I'm down to 60% after 5 hours of LOW use :/. Could I need a new battery?
Are you doing anything with the settings of the CPU, such as setting minimum frequency, keeping both CPUs online at all time (this might be set via tweaking scripts)?
In fact, ARE you using any type of tweaking scripts (V6 Turbocharger, speedy, etc)?
I don't use any of them and my battery life is pretty good. I also have an extended battery as well, so that helps.
Let the ROM settle in. After two days you should get a better picture of what it's like. Don't forget to do a battery calibration. I haven't even done that yet and have been lucky enough to have great battery longevity. Can also look into managers like Juice Defender. There's also another app I have used in the past that can limit when an app can run. Like limit Facebook from always running in the background and syncing for data. Ithink it'd LGE or LBE security?

Are you using the beta and not the alpha? The alpha has a problem with running the CPU at a high percentage when it shouldn't, which cause the battery to suck.
It is possible that you may need a new battery, but more likely is that the X2 simply has notoriously bad battery life. There are, however, things you can try to help. Go to your settings app, scroll down and click on "applications", and from there, open "running processes". Check out some of the processes. There may not be any, and if you see processes running for games or apps you haven't used in the last few minutes, it may mean that they are constantly running in the background. In that case, you may want to consider uninstalling. Try to use wifi over 3g wherever available. Screen brightness is a major battery killer, and as such, may want to keep it on the lowest setting; I've found it to be the most noticeable improvent in battery life. People are going to tell you to calibrate your battery, but I've done that many times on 2 X2s, never seen a difference. My friends and I agree its just a myth, but there's no reason not to try.
Honestly I don't know squat about batteries, but I remember hearing that the voltage of our batteries is 4.2 volts. If that's a measure of capacity like I think, you can try the app "battery left", which I believe has a voltage meter. If its less than that, maybe you should consider a replacement. Please don't take my word on this though, I can't confirm any of this to be true lol. Maybe someone else can offer their opinion on battery health.
This whole post probably seems like a big collection of thoughts. I'm tokin' right now, took me like 20 minutes to type this.
Hope I could help
To add to theredvendetta's comment, if you have your email set to check for messages, it can really have an effect on your battery. If you set it to never check, I'll bet you will see a difference.

I am using the Beta.
@theredvendetta: I installed the Battery Left widget, and when I go into details it's saying some interesting things.
I'm at 50% battery right now. For one, its saying my battery is at 3787 mV. 3.8 volts I would say considerably lower then the 4.3 it should be. My battery is only ~6 months old, but, for 4 of those months it sat unused, uncharged, and in my hot/cold car. I've only run it down a bit and charged it up 4 or 5 times this week since then.
It is reporting "battery health" as good, but idk.
Under "Accuracy" it's saying the charge reading is "Inaccurate" and the bar is totally red, indicating that the estimation of charge is very inaccurate.
Where can I calibrate the battery? I'll look around under Settings for now. EDIT: It's likely I was only around 60% charged or so when I installed the rom.
And as for background tasks, aside from the default stuff and my few widgets (not a heavy user of those) there's just Facebook+Words with Friends, Songbird, GO Keyboard. Not too terrible, I think.

I probably should have said this to begin with, but when I was talking about the voltage, I meant 4.2 was the charge when at full charge. I can see I worded my original statement poorly, apologies. Try charging up to full, and then check battery left.
When it says "innacurate", its reffering to the battery percentage reading its giving you. When you have cycled the battery once or twice, it will tell you it is "accurate", and the bar Williams turn green. You may notice parts of the bar turn green while first using the app; this means its picking up readings for the percentage of battery you're on at the time. I mean if you're on 50%, it will soon turn green halfway through the bar. After you have completely cycled the battery once or twice, it will stay green and accurate until you reset it or uninstall.
To calibrate the battery, you have to enter Android recovery. I can't remember 100%, but I believe that you hold the up volume button while booting up the phone. It may be down, you can try both. Hold it until you see text pop up that I think says "fastboot". When you see this, let go of the volume button, and now hit volume down until you see text that says "android recovery". If you accidently cycle past it, keep clicking volume down, as the list loops. When you stop on android recovery, press the up volume key. After a few seconds you will see a new screen with an exclamation mark. Press the up and down keys at the same time. A list of options will now appear. Don't use any of them unless you know what you are doing. There should be an option called advanced or something similar. Cycle to it by using the volume keys, and hit the power button to select it. There will be an option to calibrate you battery in there. Itbwill take a few seconds, and after that, return to the main menu and reboot the phone.
Good lord that took me ages to type. There's no hope with dope kids.
I feel like a broken record, but again, battery calibration does not do anything. If there's a chance the meter is off, just charge until your battery's voltage levels off and use the battery fully before charging again.

I agree with you. He asked and I answered. 'Sides, there's no harm in trying it, as there are no negative aspects to it.
Im running cm7 and the only mod im running is the 8 touch points. I do have my screen set to the most dim setting thoough. My phone gets unplugged at 5:30 in the morning though out the day I'll talk send some text might play a few games and usually be on the internet about a hour or so. When I get off at 7pm my battery is usually anywhere from 75% to 69%. A few times it has gone 18 hours and only been down to 52%. Give it some time, CM7 has by far the best battery life that Ive seen for this phone.
Yeah, after clearing the davlic cache and going through a few charge cycles, it seems to of improve greatly.
I'm running CM7 and my phone has been unplugged for 23.5 hours with medium usage including 72 minutes total voice call time and I'm currently sitting at 23%, hence my signature lol and this is a stock battery.
SBF'd from my tasty X2 MAXX
give it a few days but cycle it hard, like don't plug it in until you're below 5%. I have the BH6X (1850mAh vs. 1600mAh) so it's not much of a jump in capacity... your voltage should start out right around 4.2v and drop to about 3.5 when it's close to dead. My phone sucks at telling me how much battery is left, it always has, I typically run this thing dead every day, but some days I'll have upwards of 40% left (voltage is still above 3.8v)
I honestly don't even pay attention to the percentage 'cause I can watch an entire episode of beavis and butthead in HD with the brightness all the way up using software rendering (more power consumption) when I'm below 10% and it won't shut off on me.
it takes me almost a solid two days to kill my battery and I've been on CM7 Beta for a week as of yesterday. at first my battery life was absolute crap, but it has improved... every time you wipe the dalvik it'll take a solid 2-3 days to rebuild it. that uses much more power.
I am prepping for CM7 now. With my mostly stock X2 using Juice Defender I am getting about 1.5 days between charges. When I charge I am about 20% or less on the battery and this is with mostly lite usage. I expect once I make the switch it could take up to a week for everything to level out as it will have to synchronize many things because it will be like having a new phone. When my X2 was new it took about a week to settle in and stop the random crashes. That was also about the time the battery improved from about 1 day between charges. I will write back in a week or two once I have my phone switched and stable.
I used juice defender for awhile but I realized I was really only using it to control data. I just keep a data toggle in the notifications bar. It's really not that much of a hassle to switch it off and it reconnects fast enough. Saves quite a bit of battery power. When I was doing that with my extended battery on liberty I could get about three days.
I am actually impressed with my x2's batt life (although it is a brand new batter when I got the phone a few months ago). I used to have the HTC Desire, and it wasn't the greatest with battery life. My bone stock x2 didn't have the greatest batt life when I first got it, and still wasn't a whole lot better with cm7 installed. But now that I have installed miui on it, and screen brightness is about 70% constant, with wifi ALWAYS enabled. I am going on almost 24 hours now (maybe more??) and I am at 57% with little usage. I've used the phone maybe 2 times today for a total of about 10 minutes talk time, I have no 3g/data, other then wifi when I am at home, so I'm sure that has alot to do with it.
Another tip, that probably everyone already knows, and some people say it doesn't matter, but it seems to for me. ONLY charge your phone when it is less than 10% left, and then make sure it is charged for at least 6-8 hours before you unplug it. I know they say the newer batteries are not effected by this but my wife had the HTC Hero (worst android phone ever IMO), but she would charge it every chance she got, even if it was at 80%. Now, the phone is lucky to hold a charge for 5-6 hours with NO USAGE at all (except wifi always turned on). Granted the phone is older than dirt, and so is the battery, but still. My desire still holds a decent charge considering how old it is. I can get maybe 14-18 hours with no use on it (or very little use) with wifi always on (granted, the phone is bone dead after this time though).
I just altered the cm7 performance settings... back to normal. This combined with a custom juice defender ultimate profile has easily tripled my battery life..

Yeah I've seen nothing come from battery calibration. I have problems with my meter some days draining really quick and some days just normal. If it's bothering my I'll do a reset and that will usually sync it up. I'll try the charged voltage level off and empty thing and see if that helps.
Thanks.
hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

thank you
and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
