***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.

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

Spare Parts says "Time spent without sleeping: 53m 15s (100%)
Wow.
If I go to Battery History and change the top dropdown to Partial Wake Usage, it says Android System at the top with a bar that's at least 75% full.

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'm incredibly happy with Gingerbread (even though I admittedly only had Froyo for a day, REALLY good timing ), except for one small, minor, insignificant problem: the battery readings jump by 10%.
I scoured the topic on the Dev forum, and tried wiping the battery stats (with both the "Battery Calibration" app on the marketplace AND the instruction Kenneth gave using CWM Recovery) but it's still not reading right. I didn't install a battery percent mod, which I read could mess with the readings.
Does anybody have any other ideas? Like I said, everything else is working great, and if I didn't get the point across in the first paragraph, it's really not a HUGE deal or anything like that, just an annoyance.
Thanks!
Don't think it's Kenn's mod. The OTA 2.3.4 has similar battery jumping stats. Every time I reboot I get an extra 5-10% lol but it drains down quicker.
When you say they jump by % 10, do you mean it jumps up and down or that it only registers the charge loss in% 10 increments? If its the former then its a known issue where battery calibration is your best shot at fixing it. If its the latter, this is normal for the atrix. It only registers % 10 increments by default.

I don't think we're having the same problem. The READINGS are jumping on mine, so it'll go from 100% to 90% to 80% etc. I never see anything in between. The battery seems to be lasting as long as I could expect, considering how much I've been using it. I'm having a hard time figuring out which side of the reading it's actually on, even. Like, if it's reading 90% is it 90-100 or 80-90.
Also, just to clarify, I wasn't outright blaming Kenneth's ROM for anything, as far as I know his release is stock, and just repacked so it can be installed with CWM (maybe deodexed? Or maybe that was a different thing altogether? There's been so much coming out I can't keep track). I just didn't know if it made a difference or not, so I was as specific as possible.
Thanks for your reply though! Maybe someone can shed some light for both of us
Edit: goscrewsir, I used to get single percent readings. Since it's by default, is there a setting somewhere that I'm missing? Thanks for the info!
The last person to answer is right, the 10% incrementing is normal. It shows 90% for all the values between 80 and 90...there is a mod available to show 1% increments however, which you should be able to find in the themes and apps board.
OK, I guess I didn't notice since I installed GingerBlur almost immediately, and maybe GingerBlur had a half version of that mod built in (the system read single %, but the icon was normal)?
Thanks again to everyone for the explanations!
[MOD] StatusBar Fix for 2.3.4 - 1% Battery!! - CWM (6/28) by Nottach
Thanks neotekz, I knew where to find it. Plus the one you linked to is for HKTW.
I wonder if Nottach would be kind enough to leave out the custom battery icon. He seemed to be doing a lot of single requests in that topic, haha.
So what does the battery graph look like in 2.3.4? The stock graph that shows usage, does it look chunky and not smooth? Or does it look correct?
I seem to have a problem with the battery reading. Also if I reboot the battery goes from 85% to 99% . When I hit 70% it drops to 50% immediately. Clearing battery stats doesn't work.

he updated the mod when ken released 2.3.4. it works for both versions.
Sent from my MB860 using XDA Premium App
so does the 2.3.4 battery graph work normally on the atrix? on other phones the new battery graph shows 1% battery, so the graph is smooth and accurate.
does the atrix 2.3.4 version of this graph work the same way? or does it only show the graph in 10% chunks?
Hi
I just flashed CM7.2 yesterday. I noticed (well to be precise, and thats the problem, i did not) that if battery says 100% its still loading. Well this is also normal for stock rom, so i thought give it some time. but its loading like nearly forever at 100%
I also read some of the calibrating threads but dont want to ruin my batt by bumpcharging
Is this normal? Is there a notification (like the stock "Battery is fully loaded" or whatever its in english) anyway? as i type its still loading. 4hrs now
its normal. the full battery charge notification is touchwiz thing, cm rom doesnt have it.
use thirdparty battery app from market. some of them got full battery charge notification.
you can tell when the battery full when the battery charging icon goes and is replaced by a normal icon.
It will show 'full' instead of 'charged' in about phone.
This is when touchwiz displays the notification.

Cyanogenmod does not have battery notification. You can simply watch the icon if it show the normal battery symbol its fully charged.
IMHO that notification is pretty anoying when you charge your phone a night beside you bed ;-)
Use app- Battery HD
It's works great for me. Will give you all the necessary information.
You can also choose a setting in which the phone 'speaks' (in a robotic woman's voice) when the battery is fully charged.
Totally sweet!

I use this. Battery Full Notification
some app just notify you when the battery is reach the 100% not when fully charged.
this app just work great.
just set and forget.
I will try the Battery Full Notification. seems to be very small app. dont want to run too much useless (well...saves me from 4 clicks) stuff in background.
But now that i know its a "feature" im calmed. thought it might be my batt

I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please
I am really suffering from massive battery drain http://forum.xda-developers.com/showthread.php?t=1933012 :crying:
Did you try to delete battery stats? Or use an app to improve battery life?
I have the same issue too when booting into recovery. I don't worry about it. I suggest the same as Ramjet in your other thread.

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

Also try using you phone on min brightness auto brightness is also a battery killer

Hi everyone, I am using HTC ONE X + At&t Version with Team Venom ViperXL+ 2.0.0 Rom. Last night i downloaded an app from playstore and my battery was 40%. Furhtermore my device was running from 2 days without charge and still had 40%. Suddenly my device turned off with a beep. I thought it was the app , but to my surprise when i plugged in the charger it then turned on and the battery status was nil, and then gradually it was charging. Can someone please tell me is it normal to happen like this? i never had any issues like this, is it the battery status file issue? Please help.

Well since its a custom rom its not really "perfect". It seems it is either a "Visual bug" giving you wrong stats about how much battery is left (in which case you can use a helpful gadget like "Battery Reborn" , it has a widget with a chart to help you know how much time is left, when was the peak usage..etc)
Or It might be an actual issue with the ROM itself. In which case I suggest you check out the bug's section of the ROM. After all you can't really know until the dev for that rom replies.
Thanks for the help i will certainly download this widget and see if its a visual problem, i m currently running Battery saver widget never had a problem .. but i guess problem never tells before it comes.. .
