If your going to answer me with "You retard its only been out a day" or something like that then dont answer cause i dont need your opinion -_-...
Now if u flashed KA6 and dont mind sharing your opinion with me about your battery life on it so far.... Plsz go aheas =D
Is it better then KA5? Lol
"You retard its only been out a day"
lol jk
no one can really give you an honest statement.
It's been out a day, and a rom/phone usually needs to take 24 hours, or more to settle in and start acting normal, then if you check it should be good...
but SO FAR, my battery life's the same as KA5, excellent.
but depends on what rom your using, with NERO, i had a bit lower battery than usual(probably just me) then with Axura, incredible life.

Any of jellette's latest roms have extraordinary battery life. I'm currently running M10 and after getting up at 430 this morning, now 715 pm, still at 51%.
Sent from my nuclear powered submarine.
It's the best i've seen so far, after about 24 hours of moderate use: wifi, about 30 minutes of calling, about 30 minutes navigation, few downloads and install, i even watched an episode of the daily show, the battery is still at 50%
I think it's the best i've seen so far, but then again, I was on JFD then JI6 up until a couple of weeks ago.
Battery life has improved to nearly double what I would normally get on 2.1 , rooted & stock

interesting...my battery life has essentially been halved coming from rooted, stock JI6 (minus most bloat). if i unplug this thing at 5:50 am and listen to music (with the screen off) for 45 minutes while working out, and syncing email once an hour, the battery is at 30% by 10:30am. before the update it'd be at 80% to 85%.
any suggestions? It's getting pretty unusable honestly, especially being the owner of a nexus s as well...
just wanted to post an update that i finally got up the nerve to install modified 3e recovery which in turn let me get (and keep) Clockwork mod recovery, where i flashed the new K1B modem and wiped the battery stats.
Im conditioning the battery by letting it drain down and will charge it to full again, but so far I'm happy to report that battery life is now excellent for a vibrant.
went through heavy use today of 3g, streaming, gps, and 2.5 hours in phone calls and im at 18 percent currently (been off the charger for 13+ hours).
Very acceptable for how i use my phone. before this change it was hemorraging power and needed to be recharged twice in the same day ( mid morning and again when i got home). I'm happy with my phone again!
P.S. KB1 modem is a beast, i hit 6.1mbs down, and gps accurate to 9 meters, and under power usuage cell standby only accounted for 4% of power where as it was 20ish% before. holy crap

You can go to menu button> settings>about phone> then status gives battery level and battery use give the % of power usage by task
You can get apps for this, don't really need them.

Use anycut to make a shortcut of lbstestmode on your home screen then click "get position test". It will then display how many satellites there are in the sky and how many you've locked onto
Btw "locked on" means that your phone can see a satellite and it can see you basically. Your phone connects to many different satellites and the more it locks onto, the more accurate your location. Hope this helps

***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.
Regardless of any calibration method i try, i can never get an accurate battery reading. (Before i continue, ill point out that every app ive used to check my battery health has said "good")
Ive tried calibrating with/without the calibration app. Ive tried just deleting the batterystats via rootexplorer. ive tried calibrating before/after cycling. nothing seems to work.
the reason i know its not working, is because i will calibrate/cycle. lets say ill start a day with 100%. ill unplug my phone, leave for work, and use my phone moderately to feel out the battery drain. then at some point, ill plug it into my charger at work......just now, for example, after three hours of use my phone went from 100%-71%....i went to charge it, and once i plugged it in my percentage display changed from 71% to 63%!!! my percentage will constantly jump up and down throughout the day when i plug/unplug my phone.
anyone else experience this?
PS - its not ROM or kernel, its been happening to me for the last 2-3 months...ive flashed several roms/kernels in that timespan, and have ODINed at least once.
PPS - Ill also add that when i unplug my phone to start my day (after its been charging all night), it will stay at 100% for about 30-45min, at which point it will then start draining on an average of 1%/10min. i feel this may have something to do with it.....does it have something to do with me calibrating at too high of a voltage??
Well as for your inaccurate battery readings, i would suggest that you to odin back to stock and. Leave the phone to charge for 4hours(the time my phone takes to charge from 0-100%)then use the battery calibration app or wipe battery stats via cwm. And as for the draining it might be corrected after you calibrate it.
I know this coz I have experienced this in the past and i'd lose around 1% every 20-25mins now.

the best way to calibrate ur phone and its worked perfect for me.

So if i clearly state in the OP that it was happening to me before and after ive ODINed, and someone says you should ODIN...thats not a lazy suggestion?
or if someone says to try calibrating, when I stated several times in the OP that ive tried multiple calibration methods...thats not a lazy suggestion?
What i expect is if ive pointed out that ive already taken troubleshooting steps, then dont suggest those troubleshooting steps. no one is forcing a response, so if you dont know, simply dont answer. dont just read the title, skim the post, and give programmed suggestions.
theres absolutely nothing wrong with trying to seek out answers other than the conventional ones. ODIN and reflash are the laziest responses......granted, they will often fix problems, but there may be other ways to solve certain issues.
The goal of my OP was to see if anyone else had experienced it, and if someone responded affirmatively, i would ask them about their calibration methods and we could brainstorm. I would much rather seek out problem-solving knowledge before resorting to ODIN/reflash/new battery/new device...which teach nothing.

This is typically the method i use. i usually let it charge for an hour or so beyond when it reaches 100%, just to ensure i have a full charge. this has not worked for me. i also take it a step further and let my phone discharge all the way until it dies, let it charge overnight when powered off, then ill wipe the battery stats first thing when i wake up.

this was an extremely informative read. it doesnt shed light on all of my problems...but it definitely explains the longer battery life upon unplugging in the morning. my only question is how am i getting that extra juice when im not actually "bump charging"...i just plug it in when i go to bed, and unplug it when i wake up.....maybe my phone doesnt stop sucking in a charge the moment it hits 100%?
i agree with what he says about not paying too much attention to your battery.....but when its bouncing up and down by 20% increments, thats cause for concern haha. im going to calibrate one more time tonight, and i i get similar results i will swap batteries with another vibrant user.
do you guys suggest deep cycling, before or after wiping battery stats? (or should i just wipe stats at a full charge, and not deep cycle at all) >>> there seems to be different opinions on deep cycling throughout XDA
I have had a similar issue. After flashing Roms, plyugging and unplugging it was jumping by a good 10-15%. This turned out to be a simple bad calibration. Normal jumping should be up to 2%, more than that usually indicates bad calibration. Granted, normally nowdays, mine does not jump at all.
I recommend cycling it fully empty. That means, go ahead and drain to 0. Then let it shut off. Then turn it on again. Keep turning it on till it STOPs being able to turn on. Then charge it completely. Don't charge overnight as that will charge to 90-95% as the article suggested. Charge it while you're awake so you see when it hits 100%. It's even preffered if you charged it while the phone is off. After it hits 100%, give it another hour on the charger. You can even bump charge to ensure it hits full charge. To bump charge, after it's full, disconnect and reconnect the charger every 20 minutes for that last hour you're charging. Then unplug it, boot into recovery using the 3 buttons. Wipe the battery stats from there. Boot normally into your ROM. See if it is still jumping by 20%. Worst case scenario should be a 5% jump. Let us know what happens.
^ See, there is my confusion... there is a great example of how to calibrate, but the OP seems to get in a tiffy for offering up a suggestion he has done (calibrating). I'd also be cautious about the bump charging as that will really hurt the battery. I'm not one to try and get something for free, but why not just get a new battery?

I support the new battery notion too. It's FREE.
Drain your phone til its dead.... charge it up full.... run a battery calibration app on the market and let it die fully again then charge to 100 percent one last time... good to go!
You might even try using a differnet battery

Topshelf, I have run into these problems, There are a couple of things that cause the battery to be wonky.
1st Samsung has the battery set not to 100% but actually less (95-98%) so when it is charged and reads 100% as soon as you unplug you get a immediate reading of 95-98% (nice huh?)
The dev/mods, and others have tried to rectify this. No one has found an exact fix for this. On thing I have found that does help is to charge to 100% then unplug and then plug into the computer and recharge back to 100% (the lower milliamp off the computer seems to allow you to get to a higher percentage). Then calibrate. Now when you do that the battery calibration/battery widget/and phone All will read more close (for me +/-3%). This is one of the issues you raised.
The other is the battery drain, with some of the custom roms the gallery seems to one of the culprits, mms sometimes stays on with others and some others that are in TSR but instead of being asleep they are taking resources.
I have used systems panel to trouble shoot and that has helped me. I think you may want to ask Explodingboy70, Roman or whitehawkx, they know more on this and maybe can help.
Hope you get it solved......... stay with it you will........... I did.........
PS the mv setting for the battery is supposed to be 4200mv mine never gets above 4196mv

Charge your phone to 100% "on" > turn your phone "off" and charge up to 100% > Turn "on" and charger again to 100% > Go into Recovery > Advanced > Wipe Bstats.
If it doesn't work, let me know.
1% a min, that has to be a calibration issue. deff try what the second post said first.
ok so i just did what you told me and it is still dropping bad. i just finished it like 10 mins ago and its aready 96% with no data no wifi still idk what to do andymore.
you have to let it go through several calibrations. Charge to 100% and let it die, and recharge to 100%. go through this process several times and you will see improvement.
Ok ima try to keep doing it for the next day or two

When addressing the massive battery drain of Froyo ROMS, the battery stats wipe / calibrate is weak and pathetic. It only works as a placebo for people who don't have a scientific approach to battery drain.
Froyo ROMS on Fascinate have all kinds of battery issues. Some people notice them, some don't. Do the following and it may help:
1) toggle airplane mode each boot
2) enter / exit maps each boot
3) disable location services
4) set wifi sleep plcy. to screen off
5) disable auto rotation
Iphone 4: excellent battery life out of the box. No hacks. No forum trolling. What a novel idea!
Froyo on Fascinate is half baked and was tossed over the fence like a dog turd.

I don't think 1% an min can be attributed to any run away process or any normal or abnormal use. I may be wrong but I don't think that kind of drain rate is possible without an actual short in the hardware. I would love to hear the devs chime in on the calibration issue as my only knowledge of it is just repeating what I've read.
Oh and unplugging your phone and finding that your down to 95% is normal. Your phone won't hold the 100% charge to prevent damage from over charge. When charging it will hit 100% then stop until out drops to around 95% them start back up again.
So don't count what it "drops" in the first few secs after unplugging.
Iv been doing this for two weeks nd it still is horrible on battery.....idk what to do nemore

Why don't you try a different kernel? Maybe the PB&J variety?
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 have nothing of the sort extra installed (CM7 might of had this stuff, but I don't know).

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.
