I used ODIN to Flash Darkys_v9.2_Resurrection_Edition version. It went pretty well, everything works just fine, however, my buttery seems to run out a lot faster then the stock ROM.
I performed the following steps in an attempt to resolve this:
Calibrating Battery with Darky's ROM:
1. Use your phone until the phone switches itself off (battery empty)
2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%
4. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
5. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
6. Once charging to 100% is done, keep charger plugged in & Reboot into Recovery Mode
7. in Recovery Mode go to: advanced --> Wipe Battery Stats --> Yes-Wipe Battery Stats
8. When done: Go To --> reboot system now
9. Once system has rebooted, unplug charge
but that didn't seem to work, once I booted the device after an hour and a half I lost 10~% battery already.
Any suggestions?
Thanks.
One read all the millions of posts with exactly the same rom and problem .
Two read the Battery Faqs three flash a different rom as by all accounts including mine Darkys = poor battery life .

I did use the search and didn't find any answer.
if nothing works I'll try a different ROM.
Thanks
Yup, I installed a different rom and now my battery lasts much much longer.

I am on Darky 9.3 Extreme and after 2days 7hrs 28mins 22s, I still have 28% battery with an average use of wifi, 3G, calls and messaging. I never had any battery issue of any kind. I can post images if you want to see
Why won't i believe you?
For my sgs it caused severe battery issues. I found no other solution but to use a different rom.
I guess you have more luck than me

Battery drain issues has been completely random, and there's not particular established trend for particular ROMs. I agree with you that I'm a bit luckier. I was on stock JS7 with bad battery drain. That was what gave me the impetus to install Darkkys, since for me, I though I would be facing similar drain, but luckily, it came out better than JS7 for me.
Battery drain issues has been completely random, and there's not particular established trend for particular ROMs.
Reasonably true but some roms get multiple battery drain posts others do not .
So if rom XXX has a thousand posts with problems i would steer clear ..
The battery FAQ posts all over this forum may be of some help .
basics are to drain battery delete battery stats charge battery bump charge battery a couple of times then use the phone for a week or two .

Hi all
since a week or so i have a strange problem with my sgs and i hope you can help me to fix it
Everything works just fine (battery is accurate) until i switch off / reboot the phone
but at next boot the battery reports a very low value
(e.g. the phone has 55% battery left and after the reboot it reports only 8%)
with Froyo 2.2.1 (Speedmod Kernel) it would stay at that level until the battery has really drained to that point
With GB (JVQ - Galaxian Kernel) the battery percentage increases slowly
What i tried so far:
first of all, i deleted the battery stats for a few times and because that didn't work i upgraded to JVQ (with repartitioning and all), but that didn't solve the problem either
i don't really know what to do anymore and i hope someone can help me
thanks
Just do a few drain/ charge cycles and that should sort it

First off, wiping batterystats.bin alone won't help.
Try this:
1. Charge to 100% until it says unplug charger.
2. Wipe batterystats.bin from recovery, unplug and then reboot
3. Drain your phone's battery until it shuts itself down
4. Charge to 100% without interrupting the charge
5. Enjoy :3
thanks for the quick replay!
unfortunately thats basically what i have already done
since the problem happened the first time, i have charged the phone at least 5 times and wiped the battery stats for 2 or 3 times right after charging the phone to 100%
its true that normally i don't drain the battery completely, but yesterday i have done just that and than let the phone charge overnight - but that didn't solve the problem
i will try to fully discharge the phone a few more times and load the battery while the phone is switched off
still i hope someone has an other suggestion how to solve this annoying problem
thanks
lol - stop deleting the batterystats.bin for starters.
The batterystats needs to indentify the top and bottom markers such as 0% - 100%, delete it ONCE.
Firstly, turn the phone off, charge the phone to 100%, bump charge it, till 100% truely.
This means, unplug...then plug it in again until you keep getting 100% show up.
Boot up into recovery then delete the batterystats.bin.
Use it heavy, activate everything and drain it. Make sure it is compeltely drained, try turning the phone back on, take the battery out for about 2 mins, try turning it on again, if it doesnt turn on, you've drained it.
Plug your charger in, do not turn the phone on, let it charge to 100%, again, bump charge it until 100% truely full, turn the phone on and let it run its natural course this time.
Do not delete the batterystats.bin again, you will have to repeat the process, it will take a good 2/3 times of charge/discharge for the stats to settle.
Hopefully helps dude! Good luck
thanks pidz!
just to clarify: i have had my sgs for a half year now and i never wiped the battery stats until last week
But i haven't tried bump charging jet - i really don't like that process as it is bad for the battery but might be worth a try, thanks
it usually happens with non original batteries. did you changed a battery? or maybe you got a fake one with you phone?
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

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.

lol yes. I used video playback to drain mine. But if it's really a PITA, you can always just leave it till tomorrow to discharge naturally.

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.
Since few days ago, im using PCFighters rom. And, I have problem with charging, my battery wont charge above 50-60%. I tried deleting battery stats from recovery; i tried bump charging (although i cant charge phone while its turned off - CM7 "feature" ), i tried some method form XDA (charge phone, delete battery stats, reboot phone, remove battery from phone while rebooting, and phone still on cord etc) - but nothing works...
Battery itself lasts like usuall, 24-30hours, but this is really annoying... and, here is pic of battery usage, you can see how it oscilates on far left side, while charging, 50-60%, and thats it...
Any solution?

There are 2 possible solutions:
1. Re Flash the ROM, let it reach all load until phone turn off, charge to 100%, then Calibrate Batt, then reach the load to 0% again, then charge the batt. If the charge stay on 60%, unplug and plug your charger continuously from the outlet energy.
2. Replace your battery with a new one.
this problem have a simple solution you must download "battery calibration" or "battery calibrator" and when the phone is charged (60%) you must click the button .. if this doesn't work you can enter in recovery---> advanced---> wipe battery states

Done this already, not working (both ways)... ill reflash ROM today, and we will see does it works
Edit:
Not working... flashed ROM again, cleared dalvik/cache etc, left battery to drain out - but it wont charge over ~50% :/

Thats How I Do It
I need to flash the latest recovery.img CWM v5.0.2.7 first and then wipe battery stats.
With Battery Callibration app see how high is battery voltage, when is at 60%, then share here with us.
OK, ill check it tommorow morning and type it here... thx, imenjak
("imenjak" - ppl with same name, in our language)
After 10 hours of charging, baterry is at 52% or 3729mV... i tryed unplug/plug in for a few times, but now it wont go over 52%.
Finally the following steps helped me:
- I flashed the latest CWM recovery.img v5.0.2.7
- Boot into Recovery and did:
- "wipe cache partition"
- Inside "Advanced" both did "Wipe Dalvik Cache" and "Wipe Battery Stats"
- Power Off
- removed batterie and waited at least 5 minutes
- inserted batterie and used GT540 until it's fully empty
- charged GT540 again
- Voila: "charged 100%"

If nothing helps, try to backup your current ROM, install a different one (for example Froyo or stock Eclair) and if the same thing happens (also after calibration) then you will know for sure that the problem is hardware nature and your battery is dying. But if on different ROM you have normal battery charging then its a very weird bug.
Good luck, imenjak!

OK, i have CWM V4.0.1.4; and never took battery for 5min or more.... first I will try with battery, than with new CWM; and on the end with another ROM... TY all for advices
Well, problem is solved... funny, but problem was in charger, or data-cable :/ With new charger, I have no more this stupid problem
Like I told.
Sent using Tt.
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.

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.
