Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Click to expand...

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
Hi to all i am facing massive drains in battery
My phone recharges in 1.5 hours completely.
But i dont think that this is reliable as if i use my ideos with automatic brightness and on demand 400-1000 franco kernel.i can play game for continously 1.5 hours maximum.
And on wifi its about 4 hours.
I think its battery calibration issue.
If any expert here make a guide to properly calibrate our batteries than we can get most out of them.
So experts please come one step ahead.

To calibrate the battery you have to charge the battery to 100% and leave charging after 100% for about 30 minutes. After the 30 min, reboot into CWM, go into advanced and select Wipe Battery Stats. Reboot the phone again.
You won't notice much of change initially, because you have to repeat this process at least 3-4 times. In about a week time, you'll see that battery will last twice as longer.
This may not work for everybody, but it DEFINITELY worked for me.
Just download this app, plug your phone to charger, when that app shows over 4200mV press "Battery Calibration" button and then use your battery to 0% and then charge it back to 100%.

Gonna try this. The first time I did it I didn't notice much but today my battery has surprised me greatly.
Do you also use something Juice Defender?
NO juice defender app! That's making things worse, in my opinion.

I have it too. No help so far.
Download the app "battery calibration" from the market, and follow the instructions in the app.
No use man tried all the things recommended battery savers ,calibration ,stopping services blah blah .... etc .I be live is time to say goodbye to this rom and return to plain old Eclair.It is no fun to worry when the battery will go flat on me!
Set min CPU to 19 MHz (only in custom kernels)
No lag, reboot, etc at all.
i feel also, my x8 got faster battery drain...any solution about that ?
did u guys try wiping the battery stats in CWM??? it usually helps. i had battery drains everytime i newly installed gingerdx.
Some of the tips to save your battery i learnt overtime in XDA posts thanks to those threads.. sry i dont remember the exact ones
1) Disable Haptic Feed back. ( The phone vibrates during certain UI interactions and hard button presses)
2) Keep your phone's brightness low(less than 30% if possible). If your phone has a Light Sensor, then enable Auto Brightness so that your screen's brightness changes according to to your surroundings light levels
3) Download RAM manager(requires root, if you haven't rooted your phone check out here) and keep your RAM free soa as to avoid many apps running uselessly. You can check out about RAM Manager here and download it.
4) Use Juice Defender Battery saver. This app does a neat job and really saves your battery life.
I use a Sony Ericsson W8 for now and I get a battery life of roughly three days with moderate use!
To know more about Juice Defender and to download it see here.
5) Charge your phone occasionally to enhance your battery life.
6) If you use a Custom ROM and Custom Kernel you can make use of Undervolt modules.
7) Use SET CPU (requires root, if you haven't rooted your phone check out here) to underclock your mobile processor when your phone is not in genuine use.
8) Apps like Facebook for Android, Music etc occupy your RAM even after you close them. They run as an actual background process rather than a Cache Background Process.
So goto Settings -> Applications -> Running Services to close them manually(This frees more RAM as well as increases your battery life)
9) This one is for rooted phones with Clockworkmod Recovery or xRecovery. In case you face an abnormal battery drain try this. Charge your phone to 100% and reboot your phoneto CWM menu or xRecovery menu and select advanced and Wipe battery stats alone and reboot and charge your phone for another ten minutes and Voila! your phone battery would last longer than it normally did!!!
10) Uninstall unused applications so as to prevent battery drain.

Hello Guys, I may have figured out the battery drain problem. I was previously using Froyobread on my W8. I decided to upgrade it to GDX so I flashed it.
Before flashing, my battery was at 25-27%...Right after flashing though, I noticed that it went up to 46%??? (My phone was not plugged through USB or charger during update process)
Could this be the reason for the so-called battery drain issue? Meaning the phone "thinks" its fully charged even if its not?

u better wipe the battery stats after u install a custom rom like GDX ..... charging the phone to 100 percent and then wiping the battery stats keeps the phone in a stable battery condition and there wont be battery drains.....
Okay, so I noticed that the batt drain was unacceptable the first time I installed gdx (it ate like 2% every 5min on standby) so I read all the advices here and did my own combination.
Heres what I did...
I switched back to froyobread then fully charged the phone. I then reset the bat stats thru CWM then charged the phone again. I did this like 3x coz every time I reset the stats, it would drop 5-8%...after that, I then installed GDX and once again, fully charged it the wiped stats thru CWM and using battery calibration. After that, I noticed a big change in bat life. Its now about 12hrs running under normal usage (a few calls, sms and some wifi), the batt is still at 88%...whereas before, it would have been around 30ish already when I was running froyo.
Could it be that GDX jumbles up the numbers when it is installed on phones with bad battery stats?
Just sharing my experiences...
OT: GDX rocks!

When i must wipe my Battery Stats?
Always when you Flash a new Rom or Reflash the rom you must have to wipe your Battery Stats to have the best Battery life from your Device.
How to wipe Battery Stats?
1. charging the battery FULLY
2. boot device to CWM Recovery
3. advanced/Wipe Battery Stats
4. reboot device
5. don't charge the device until the battery still turns off your device because it empty (do not drain with heavy apps like video streaming ect.)
6. now again FULLY charge without interruption
7. Have fun ^^
Hit the Thanks Button if it help!
Thanks
I have woundered why it didn't work on my phone and that was becuse i charged it while i wiped it and i didn't let it drain all the battery
well...you can also wipe that in the xRecovery if you have it
the reason of wiping it is because the battery status will not be accurate.
also, if you found your battery is draining, try to wipe it, then check the running services if there are too much apps running in the background~

wipe it when battery has 100% and after you flashed new rom
The better and easiest way is with battery calibration.apk
Download this: http://db.tt/Ohb9vGgP
And follow the instructions
actually, it usually takes a longer time for the battery to get from 99% to 100%
the reason is... idk...
but even thought it is 99%, it takes a shorter time to consume the battery than it is charged to 100%
thats my experience
If you read the phone manual, it says that happens because it is expanding battery life... (??)

after you wipe the battery stats and reboot your device you have to wait untill your device battery is empty and the phone turned off by herself. 0% battery . After device turned off by herself, charge your device again to 100% without any interruption like reboot or unplug power plug.
Understand? Please excuse my english is not as well.

@azyar
1. Charge the phone (100%)
2. Wipe battery stats
3. Reboot the phone
4. Now use the phone until the battery has gone from 100% to 0% (when the battery reaches 0%, it will turn off by itself)
5. Now charge the phone 100% again without interruptions (don't even touch it)
When battery level has reached 100% (not 99%), you may use your phone again.
Hello, i'm currently with quarx CM10 last build (2 nov). First time i installed it i noticed it help A LOT with battery consumption.. from 12 midnight till 10 am from the other day it went from 99 to 97... that is.. like a miracle. then i did something stupid.. i used "battery calibrator" and it ruined it. Today it wen from 12 to 10 am in the morning with 99 to 60 then 49 (typical battery jump)...
I repeat, it's in the night, were wifi is off, refresh is off and nothing (that's what i'm planning to discover) is running or updating.
I attach some screens.
1) first install of the new rom. you can see it sleeps like a baby.... plain.
2).. goes down.. and down... even though i'm not using it.
any comments, help or suggestions? thanks in advanced!

Make your phone recalibrate the battery. Follow the following steps:
1 Use the phone till you have 10% or less battery left.
2 Wipe battery stats from 2ndinit recovery.
3 Boot into CM10.
4 Charge your battery to 100%.
Doing this will make the phone generate a new battery stats file and should solve your problems.

i'll try that. but already done it when installed the last build for the second time. i do wipe cache / dalvik / batt stats then flash ROM and all over again with the wipes.

If you've uninstalled your battery calibrator app or if you've not used it after the wipe, then you shouldn't have any abnormal battery drain...
If wiping battery stats doesn't work, then most people recommend reflashing the ROM, but you've already done that, so you shouldn't have the battery drain now.
Just put your phone to sleep for a few hours, and let's see what happens after doing that.
This is what i did after seeing the sudden drop the other night:
- let it drain normal till the day finishes (at midnight, that's when i did the following)
- charged the battery to 100% and turn off phone.
- pull battery., connect charger to wall and recovery.
- install ROM without battery on. Wipe cache, dalvik, stats batt, install rom, wipe cache, dalvik and statts (again)
- boot into cm10, turn off screen and went to sleep.
- THIS morning, i saw it drained me up to 60 all night.
...
so as you can see.. i've already seen that after reflashing nothing has happened.
no, i didn't use again the calibrator.

I'm not 100% sure, but as far as I remember, the battery stats gets generated while CHARGING a drained battery.
That's why you should drain the battery, wipe stats and THEN charge it to 100%. As it charges, the battery sensor detects levels (15, 30, 60 and such I think) and generates the battery stats based on these readings.
Afterwards, based on these stats, it generates a reading of battery drain, as the battery sensor itself senses only certain levels.
So, drain, wipe and THEN charge. Do this and let me know if the problem still persists.

hmmm! never tried that!.. i was just charging it and it's in 90.. so i'll let it drain and tell you later thanks for that suggestion.
Still open to other comments though thanks to everyone who reads this.

Just read and engrave to your memory folks! Battery calibration never ever had a positive effect on the battery life and the battery usage shown in the android in-built "Battery Use"-app... and by the way, the stats are reset every time you unplug your nearly fully charged phone from the cable.
Hey, rather than blaming your battery stats I'd search for a process running all the time. Looks like something is keeping the phone awake.
The battery calibration IS A MYTH, as explained here, so don't waste your time wiping the values in Recovery. If you don't find any hyper-active processes with the following procedure, the drops might be related to a worn battery (I don't know how old your phone/battery is).
Open a terminal console and type:
$ top -n 1|head
(if you don't have Hacker's Keyboard installed and selected as Input Method you might need to copy and paste the line above, off course without the dollar sign).
Look at the processes listed as output and paste them here.

Hola slim , thanks for answering. here's the screen
You had it coming since you are using Swipe... It's chewing up your CPU, and consequently your battery. Search the site. Off the top of my head I think it was a common issue.

Swype? really?? shoot.. i love it.. even though i don't use it that much. Searched a bit but couldn't find much. Gonna try freezing it and see what happens. thanks.
Finally i managed with your help to accomplish some good sleep! here's the screen. i think it's awesome, never ever seen this.
thank you!!
we'll see if it gets better.
There's an interesting lesson to be learned here: if no deep sleep can be achieved, don't blame the ROM, and look for a stubborn process which refuses to stop when the kernel tell is to.
