***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.

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.

Call T-Mo and tell them and get a new battery.... they WILL give you one.
the best way to calibrate ur phone and its worked perfect for me. Charge it to 100% and then unplug it and as soon as unplug it go to sgs tools and run apply script and inside apply script there is delete battery stats. Click on that and it will take less then 10 sec and ur battery will be running great. Now this works great on my phone i hope it works on urs nicely.

Please read this article fully to understand why it happens and why it SHOULD happen.

It sounds like a bad calibration issue to me but then again I can't be sure, especially if you said you have done a calibration correctly. You can try a new battery like the poster above me suggests.

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

My phone drains the battery very quickly from 100% to 1% but after reaching 1% it can be used for hours.Last time after the full charge battery dropped from 100-1% in about 2 1/2 hours of use on WiFi but after that it lasted for more than 13 hours on 1% but the Network data, Bluetooth and WiFi was off.
Currently i am running CM7 stable (battery fix is also applied) i was also facing such issues on the stock 2.3.4.

I bought my Atrix 3 weeks ago. My previous device was also another Motorola, Milestone.
When I first started to use Atrix I found that the battery was draining so quickly even I didn’t install any apps yet. It was becoming 1% in 70 minutes with full display and running default apps.
I tried to full battery several times, did factory resets and finally went back to shop. The shop replaced the battery with another new one.
Still it happened same problem. Then they changed my device with another new one. It was same, too.
I would give it back to shop but last time I decided to discharge it until it turns off.
At this point I found that discharging takes long time after it became 1%. For example by heavy using it becomes 1% in 70 minutes, then it takes at least 200 minutes more even I watch videos via Youtube, play games etc.. It means in total it takes at least 4,5 hours with full display and heavy usage. That’s OK for me as battery life.
But I want my battery meter show correct percentage. Then I can be able to know when it will turn off.
I tried battery calibration several times. I search a lot about this problem but found nothing. Probably people thinks that their battery life is too short.
So cannot find solution.
Summary: My Atrix’s battery meter immediately drop to 1% and then runs 3 times longer than previous 99%. PLEASE HELP ME TO CORRECT MY BATTERY METER DISPLAY.

I don't know. I bought it, and unlocked it directly, then flash CM7 Rom, but noticed that the battery drain very fast. However, after the indicator becomes 1%, I can still use rather a long time. I thought it was an error on battery meter, but I can't make it display correctly through calibration.
Now if the battery is fully charged, I can still use rather a long time after the indicator becomes 1%. But after the battery drained, it can't be charged completely. It really disappoints me very much.

Ya that's the same problem i have i think its something to do with phone recognizing the mah capacity of the battery if u can see the charge-full-design in sys/class/power-supply/battery/charge-full-design u will notice it showing only 500 which should be 1880 that's why our phone drops and charge quickly according the capacity its getting from charge-full-design.
This value can be changed on other phone but for Motorola i have not found any tutorial or app to do so

And for charging don't take off the phone from charging on 100% bcoz when the phone battery meter is showing 100% its battery mv is less than 3900mv and if u keep it on charge after 100% battery mv value will gradually go up to 4200mv which is the actual capacity of the battery.

Oh, thanks. The value in sys/class/power-supply/battery/charge-full-design is just a result, representing the battery statue. So the key is that the battery capacity can't be recognized correctly by the phone. I just test another battery, and the value 1880!
But the former battery doesn't look like a fake one. Actually, I bought them together. I can't understand.
Hi everyone. I hope this is the right forums for this thread.
I noticed a decrease my the uptime of my phone over the past few months - which is due to the age of the battery I guess, no nothing alarming.
But a few days ago, I flashed a custom rom (I was on Supernexus 2.0 - http://forum.xda-developers.com/showthread.php?t=2076650) Slimbean build 8 (http://forum.xda-developers.com/showthread.php?t=2060541) and all of a sudden my battery went haywire.
The phone would heat up for no reason (as if on charge + everything toggled on + playing a game and microwaving it at the same time) and I lost 40-50% over 20ish minutes.
I reflashed it with the same rom and the problem stayed though it was less frequent. Still I barely manage 4 hours without a charge (lasted at least 20 before that flash)
I went back to Supernexus (v3.0 http://forum.xda-developers.com/showthread.php?t=2407449). Battery life seems to have improved at bit and phone heats up less.
However on using the phone moderately - some internet browsing over wifi - I lost about 30% over 30 minutes which is at least twice as much as what I was experiencing.
On checking battery usage I noticed "Android OS" was coming on top (same as with previous rom) as opposed to the screen which was eating up most of my battery before.
I checked BBS but saw nothing out of the ordinary but maybe I can't read it properly since I'm not used to it.
So I don't know what to do now. Help anyone?
Edit: Added BBS log
Try a new battery (Go with the obvious stuff first).

Why not post the BBS log then? Maybe somebody else can read it properly for you

I didn't see your message. I have no access to another battery unless buying one of course - which I'd rather avoid doing if it's not the problem.
I don't see this BBS log corresponding in any way with what you said in your first post.
From the log one can see that your battery dropped by about 70% within about 10h, i.e. 3.5% / 30min and not 30% / 30min as you said.
With a screen-on time of 1h 28m within those 10h 18m total time, the values are not really that bad I think.
To further improve the situation you should take care of the first wakelock (NetworkLocationLocator). Without this service waking up your phone permanently it will remain an additional 35m in deep sleep, consuming very little battery. Use google or search on XDA for what you have to disable to get rid of this wakelock.

Well when I went to bed it was at 100% charge. 87% on waking up (~8.30). I checked my mails, and browsed the net a bit (~9.00) it was at 56%
I fiddled around in google services. I didn't check it after flashing. Some stuff were checked by default. Will see how goes.

I've been running into similar issues, and doing a battery calibration seems to have helped me (so far). My phone would use battery quickly and also shut off without warning. I have used the option to "Reset Fuel-Gage Chip" in STweaks when running Siyah Kernel, but since I'm using SuperNexus 3.0 (not sure if I can use Siyah Kernel with it), I downloaded an app off the play store last night simply called "Battery Calibration". I'm still letting the battery drain completely so I'm not sure how well it works yet. Apparently it just deletes the batterystats.bin file.
After running the Fuel-Gage reset on my previous ROM, my phone no longer shuts off without warning. It would start to flicker the screen, kill the data, and then shut off with plenty of battery left according to the OS.
Doing this may hopefully help you as well, since you've been switching ROM's.
Hi everyone,
I am really helpless and do not know what to do anymore. My S9+ (EXYNOS) is draining battery overnight, in 6 and a half hours it drains 10%, even if always on displey is set to be turned of between 23h - 06h.
I am on the latest BTU firmware, I have tryied every tip and solution which I found on xda in order to get it better but it is still the same. I turned of almost all features like sync, location and also set all apps to be power saving.
If I use the phone a lot, I will get 4-5 maybe even 6 hours of SOT, but if I do not use it a lot, I will have 2-3 hours of SOT in total of 16 hours usage.
Any help or tips? I do not have any battery draining apps installed.
When I go to check in the battery stats I do not see anything suspicius, it says AOD 2 %, Device Idle 2%, Android OS 1%, Android System 1%, Screen 1%, Device is passive 1%.
Now I am trying it with a all black theme but still no improvement
Now I am thinking on going back to factory settings, because it seems that my battery was better (at last a little) before I tweaked and turned of many of the features.
Should I try factory reset, and if it does not help what is your proposal?
Another thing is that somethimes my phone gets hot without any reason, idle-ing or normal usage, that drains then the battery a lot. In situations like gaming etc it does not heat.
Did you try the app BetterBatteryStats? It works also with unrooted phones, if you can apply some adb commands with your PC. This app will give much more details about your battery consumption, including wakelocks.
Alternative would be GSAM Battery Monitor...its free, but not as detailed regarding wakelocks as far as i know.

No I did not try it, because on earlier phones I used it but did not know how to read it properly. I will install it now and post tomorrow the results so you can help me know what is going on.
Now I installed it but never used ABD and do not know hot to give the permission with it. In facts I used it maybe 5 years ago, now I will install it and try again, it is not that hard.

I think you should factory reset it. I had the same issue and now that I factory reset it and left most of the features as is (but I disabled bixby) it's been pretty good. Losing around 1-3% at night and at least 5 hours of SOT when I use it sparingly with around 24 hours off the charger. If I use it heavily I get around 8-almost 9 hours SOT for around 12 hours off the charger with around 15% consistently.

Thanks for the feedback. You gave me hope!
First of all I will try to discharge it once to 0% and take all juice out of the battery, maybe the system bugged because I always charge it as soon as I get as low as 40%.
If that does not help, then I will factory reset for sure. If it helped you I have hope that it will help me also.
I factory resetted few times. It seemed like it helped initially. But it actually did not.

I have factory reseted yesterday, and my batter life now is much better. Got 6 Hours SOT with 24 hours of total battery usage. In betterbatterystats I do not see anything anymore that drains it.
I need to mention that I have reinstalled everything manually, I did not wanted to import any backups just to be sure.

Actually I got better battery life after factory resetting but after few days it again became like before.Repeated it ,same outcome. so said it didn't help . Manual apps installations, not taking help from Samsung swtich did nothing.

Then I think that some of the apps you are installing is draining the battery. I am just very careful at what I install, and I monitor the battery behavior after every new app.

Do not have such app installed.
All of you uninstall Facebook and get a descent battery life.... Stop blaming Samsung... Most of the drain is due to the apps you use and the permissions you've granted to them....
Facebook only through Samsug browser. Facebook and messenger is a badly crafted app. The author should be humbly. Disable his activity and close him in jail. Do not deserve anything else. It will never be better
