Sorry for mistakes, hope it's not hard to understand
Looks like i have smth like this - http://forum.xda-developers.com/showthread.php?t=1515020 but on my RAZR XT910
When i bought my RAZR, everything was ok it was on 2.3.5 droid, when 2.3.6 released everything still was perfect, but when i started trying to setup custom ROMs, this issue started... I tried to get back to 2.3.5 through RSD - its not helped. Now i'm on T-Mobile 4.0.4, everything is the same.
Fully charged phone, idling, some calls, it goes to 80%, then it jumps to 20% then to 5%(during this, voltage drops to 3.5, but then goes up to 4.1-4.0 as it must be!) . Phone works well, it took about 4 hours for battery drainer to drain this "5%".
I tried to fully charge\discharge without using phone, i tried any tutorials that will help to "calibrate" battery. Nothing helped.
I think it happens when Voltage drops to 3.5, OS thinks that its discharged, but when it goes back to 4.1, battery lvl is still low.
Maybe someone can help me with this issue...
Now i just added battery info widget, which shows me Voltage, so i can understand charge lvl... thats annoying
And i cant go to Motorola Service(No official service in Russia) and cant return my phone, it will took a lot of time... and i think this issue must be fixed..
have you tried like the battery calibration apps in the app market?
i tried a lot of apps from market, and nothing helped.
Try do this:
Manual Calibration method:
A) Charge your phone to 100% (and let the phone charge for half an hour after the 100%)
B) Install bootstrap recovery
C) Reboot your phone through the bootstrap recovery program
D) In recovery go to advanced>wipe battery stats>Yes, wipe battery stats
E) Reboot your phone
F) Do 2 or 3 full charge/discharge cycle (100% - 15% < X =< 0% )
If this won't do, flash the stock rom and send it to RMA.
Never let the phone to reach 0% and die, your battery will take damages 'cause of that.
i think bootstrap cant be installed on T-Mobile 4.0.4
If you're rooted, you can install this
I've used it on the T-Mobile Leak without problems. Flashed the overclock.zip with it (But no overclocking on the Leak, the script won't work)
The risk is the wipe. I'm not sure, if it messed up with your Phone

That is true, but I wonder if Android seriously lets you drop your cells to 0%... It still has enough capacity to shut itself down without interruption. So I guess there might be an internal protection against reaching "real 0% charge".
Still it is not too healthy for your battery

thanks! razr is rooted, so it works!
now i'm going to test what Syriochan said
@sekall: yeah it is possible that 1% (or maybe 5%) remains, but it is also true that no developers noticed something during kernel developing for any android device. So it may be true but it's better to not let it drop under 10% or 5%
@amletika: Not sure if calibration app do the same (never tried one, always used this method) but i've had 7 android phones so far and battery life was always at it's maximum after wipe and cycles. (I believe battery stats are kernel or data related so i don't know if this will work for you, consider that maybe hardware is at fault in this case)

Please post back after you do.
I have setup ics bootstrap. And made battery wipe immediately, when my phone was about 3.9V and was saying its 5% of battery. When i rebooted it was saying that this is 30%. Then i charged to 100% waited a little more and unplugged. Its about 24hours of using with normal load, and there was no battery lvl jumps!! Thank you guys!
P.s. i dont know what battery calibration apps does, I tried a lot of them, but only wipe through ics bootstrap recovery helped!

***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.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

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.

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.

Interesting article on Rootzwiki:
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

myth
maybe a myth and from everything i have read (that article included) it seems to be. but im ok with the placebo affect or whatever bc i at least FEEL like it has helped since i did it after getting on cm9 beta 0.2.0 or whatev. not on beta 0.3 battery has been sucked hard as all get out, but such is life.
I have a question/comment about this. When a ROM is flashed I always wipe and format /data, /system, /cache, /davlik-cache, and factory reset. At this time I power down and recharge although the recharge may not matter as the lowest I've been was 85%. After recharge I boot into CWM and wipe/factory reset again then allow the phone to reboot. Isn't the batterystats.bin file in one of those places I wiped/formatted?
Once it's booted I just turn off and power up again then activate. Out of all the different ROMs I have tried this usually works very well. There was only one time my battery life was poor after flashing and I tried a battery wipe app and it still didn't help. I finally attributed it to the ROM and flashed a different one. Following the same process the new ROM was installed and battery life is great again. Did this yesterday flashing Rocko unlocked 3.0. After 4 to 4-1/2 hours of heavy use, when I say heavy I mean heavy, I am still at nearly 70% battery. If it works the way it looks to, I'll be getting at least 10-12 hours on a charge, probably more.

Calibration
So what you are saying since I have a Photon with an extended battery even rooting it won't calibrate the battery. It sits at 1% for hours. Had an HTC prior and didn't have this problem. Waste of money getting an extended battery when you don't know when it is going to die on you.

Not at all. What I'm saying is I personally don't use ine as I wipe battery stats as part of ny flashing process and do my first boot on a new rom with my battery at 100%. That works for me.
If you're switching to an extended battery you may need to wipe battery stats. This can be done with a battery calibration app or from within CWM, if you've unlocked and installed a custom recovery.
BTW: Rooting will allow you to install and run a batt cal app but rooting alone will not calibrate your battery.

Hello
Recently the battery on my phone very quickly discharged.
The phone is after a hard reset without any applications installed.
When it is almost unused batteries lasts about 5 hours
android os 88%
phone idle 5%
display 4%
stanby mobile 3%
When surfing the Internet or make the call battery is discharged after 1-2 hours.
I'm going to send the phone for warranty repair in UK.
Has anyone had a similar problem?
How long will it take to repair it?
Looks like some application is using up lots off battery. Try resetting your phone, install apps one by one.. If student you lose battery life that's the culprit.

It's not an app that's using up battery life, it's the "Android OS" itself. Uninstalling apps would have a small effect.
Though I do recommend a factory reset, it could be a setting that is using up all this battery.
Battery usage when turned OFF???
I've seen something that really surprised me. I have two Razrs, nearly identically configured. One of them I turn off most of the week except when I need to tether. I charge it once a week.
I thought this was a fluke, but it's happening consistently since ICS:
It used to be when I charged the battery once a week, this phone was nearly completely charged and only took a minute or so to reach 100% charge.
Now under ICS, when I plug the phone in for charging once a week, the battery meter reads below 50% and takes a couple of hours to charge up to 100%.
What has changed with ICS?
Is there something still running when I turn the phone off now? It would seem to me that OFF should mean OFF.
Or, is the ICS battery meter more accurate? Or does the meter need to be reset to 0 somehow? I did do a factory reset after installing ICS.
Any shared wisdom would be greatly appreciated.

With those stats, there's nothing wrong with the battery. I've never seen the Android OS use more power than the display (doesn't make any sense why it should). There's something running intensely on your phone. The bloatware is considered part of the OS (motorola apps), try disabling some of them. Otherwise I'd suggest a factory reset/cache wipe but since you've already done that, try re-downloading the OTA and installing all over again

Looks like some application is using up lots off battery. Try resetting your phone, install apps one by one.. If student you lose battery life that's the culprit.

There is no applications installled on my phone.
It is just after factory reset.
Its one of the famous "Android OS" suspend bufg which makes the cpu not to go in deep sleep.I am facing the same problem right now but couldnt find a solution
I sent my phone to repair centre twice but my problem still is not fixed. Sometimes it works ok but sometimes battery lasts about 5 hours.
motorola staff ban me on motorola forum because I said that I’m disappointed their service.
I know one thing , never buy motorola again.

Hello,
After reading other threads, I've decided that I should post my case to see if I get a better answer.
A couple of days ago after being with SuperNexus 2.0 for a few months I decided to try the stock LSS ROM, I didn't like it and went back to SuperNexus again wiping the Battery Stats in the process to see if my battery life could improve (I know it's a myth, but I tried it anyway). After this my 1.2 years old battery has been crazy:
- Sometimes it will completely discharge it doesn't matter at what percentage the battery is.
- Sometimes the phone will shut down like if the battery is at 0% and it won't turn on again, but if I connect it to the charger it will show some charge (close to the one it has before the phone shut down) and the phone will turn on again. After this I can immediately remove the charger and the phone will work like normal.
What I don't like is that just before the phone randomly shuts down, the screen starts blinking and/or the phone hangs (it doesn't respond to the touch). I'm worry this could be damaging the phone itself.
Please refer to the screenshots (there is not photoshop involved, I swear).
I've tried to charge it to 100% (trying to get it as close to 4.2V as possible), I have pump charged it (disconnect/connect the charger until it doesn't drop to less than 100% immediately), reflash the ROM (wiping/format system, data, dalvik, cache, etc. the usual suspects), etc. but no luck.
I know it looks like a faulty battery, but it has never shown this behavior until I sadly deleted the Battery Stats. Will a new battery solve the problem or it will just be the same?
Any thoughts? Any help/recommendation will be appreciated.
Thanks in advance for the help.
Cheers.
P.S.: I have to say that before all this I was running Dori 9.14, but I ran the Kernel and the ROM wipe scripts (I know the ROM wipe runs the Kernel script too) between flashes.

Wiping Battery Stats is never a problem, people even do that to reset Battery estimates, try a reflash and a more stable kernel. As far as I know Dori 9.14 is not playing nice with some people.

Yes it sounds weird that deleting a file will screw your battery, but the coincidence here is huge, that's what I don't understand. With respect to Dori 9.14 (I only used it for a couple of weeks), yes i was running it before I did all this, I'm now running the stock Kernel that comes with SuperNexus (which never gave this kind of problems before).
I also removed the battery to see if it was maybe a faulty connection, but it stays in place very tightly.
Cheers.

Yes your coincidence is just too much, hmm.. Weird.. I don't know what to say? Battery Recalibration? Beat a myth with a myth I say.
