Hi all I did this last night and it worked wonders on my battery. Before this with screen brightness at about 20% and 10 hours of being on the battery would be dead. The screen on time was 3h15m at best before it would die. After I did this I tested my battery by playing a movie, games, web and texting. When I put my phone on the charger last night screen on time was 5h flat. I was amazed. So I thought I'd type this up for anyone with battery woes. You need to be rooted and Clockwork installed.
1. Dial *22899 and let it do its thing. This helped my battery drain while in standby. Now drains about 1% every 3 hours of standby.
2. Charge phone to 100% (phone on)
3. When the charge hits 100% power down the phone
4. A green battery will show on screen and show its not fully charged. Leave it on the charger until it shows 100% (phone will vibrate to let you know and state 100%, do not unplug phone)
5. Once it reaches 100% boot into recovery by holding both volume keys and power until the Samsung logo appears.
6. Choose "apply update.zip" (use the home key for selection)
7. You are now in Clockwork. Use the volume keys to navigate to "advanced" and the back softkey to select it.
8. In the advanced menu select "wipe battery stats" (there will be no conformation)
9. Back in the advanced menu select "wipe dalvik cache"
10. Now back into the main menu and select 'wipe cache"
11. Select "reboot phone" and wait for it to reboot (will take longer than normal)
12. Once fully loaded unplug the charger and run the phone until the 5% warning then plug back in
So, it sounds like this battery issue only affected those that were rooted to begin with and had to manually clear thiese caches?
I have not noticed any different (good or bad) with my battery on stock only builds DI01 to DL09.

Yea mine kinda went south after I flashed Dj05 awhile back. Alot of users are reporting worse battery after DL09 too though so I thought this may also apply to them.
Battery life is also affected by your kernel and rom combo. Adyrnalyne's kernels seem to have awesome battery life. I last charged my phone saturday night and it's just now dropped down to 17%. However I also did a full wipe including battery stats and davlik when I installed superclean and this kernel.

Yea Ad's were best for me too im on Blackhole 2.4 and Ad's 12/30
Did not work for me
I tried doing this multiple times and it did not work for me. After updating to DJ05 I started to have problems with my battery draining extremely fast (about 3x faster than on DI01). So I upgraded to DL09 thinking it might fix the problem, but it did not. What did work is draining the battery down to 0% and the phone shut off. Then I plugged the phone in and held the volume up/down keys and power button to get in to recovery. I then applied the update.zip to get in to clockwork recovery and scrolled down to the advanced menu and wiped the battery stats. When I rebooted the phone the battery drain was better than when I was on DI01. Not sure if this will work for anyone else but it worked for me.
Yeah, wiping the battery stats when making any major changes seems to help a lot.

I did that too and it didnt help until I wiped battery stats AND cache
Typically I always charge to 100% with the phone off then wipe stats whenever I install a new rom. Was curious why my standby was killing battery on DJ09 and not DJ05, so that *22899 reset helped a bunch.
I went from around 68% no signal from standby to 28% in the short time I've tested.

gonna try this. I was on DL09 for awhile but battery sucked. went back to DI01 but couldn't handle the GPS issue. Going to try this and see if it fixes my issues w/ DL09 and battery.

this worked for me... I has previously just tried wiping battery stats to see if the battery life would improve. I had also changed kernels and switched to dj09 modem so I want sure who the culprit was. I also tried another corrective step by letting the batery drain to zero then turning off and charging to 100% before wiping batt stats but that didn't work either. I am back to normal now which was already pretty good. I should have never messed with the settings in the first place but was curious

so you did the drain then wiped battery status?
jv
I can't believe I didn't know this before. Huge difference. My method was pretty much like the first post. Totally drained battery, dialed the reset number, charged phone to 100% while off, unplugged and replugged until fully charged, wiped battery stats and caches, and I'm still draining. At 43% after 19 hours of lighter use.

Not sure if *22899 fixed my battery issue, but I have now been at 91% after 1 1/2 hour WITH wifi enabled! I've received a few emails only. Not really been messing with the phone. Seems to be alot better then the first time I had DL09.
jv
After a few downloads, a few google talk sessions and more pushed emails it has been 3.5 hours since unplugged and I'm at 80%.... I'm going to have to say that it was the *22899 that helped me.
jv
ahhh battery goodness again
Battery life is worlds better after doing this.
I would go through a fully charged battery in under 6hrs before... as of now ive been on battery since lastnight at 8 and even after a night of usage, no charge overnight, and using it all day today I still have 28% battery.
Thanks a million

You only dialed *22899? didn't do the other steps?
I tried dialing *22899 and it says programming and it reaches to Lock Code password set... and it seems to not be doing anything. Is it done?

Yup. Well I did wipe cache. Don't remember when I did it, though. But at some point after updating to DL09 I did wipe cache. It's been about 2.5 hours since I edited my last post and I've only lost 10% after a few emails and some text. I've even had wireless on since unplugging it. Something fixed it. I did flash a different modem. I flashed http://forum.xda-developers.com/showthread.php?t=908451
jv
edit: forgot to mention that I am using Adrynlyn's test2 1/16 voodoo5 kernel
My results were for dialing just *22899, without doing the other extra steps...
so far 8 hours unplugged from the charger and I'm down to 71% which seems a bit better than previously ...
This worked great. I charged last night to 100% and then this morning wiped stats around 6:30. I have been using it all day with WIFI and 25% brightness and 11 hours later I have 73% battery life left. I also noticed Standby is on 18% which is a lot lower than it has been in the past.
Thanks again for this little tip.
Any idea if just the *22899 will help out a non rooted fascinate without wiping the battery stats? My wife doesn't want me to mess with her phone.
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 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;
so over the last few months i have flashed many custom roms, kernels etc...and always had battery issues...i have tried jugs battery fix, wiping battery stats..following many other battery optimization threads..but i never got the battery life i once had (when i first bought my phone)...
a few days ago my phone totally crashed..wouldnt charge etc..and i ended up having to do a complete restore..i did this by following these instructions
http://www.youtube.com/watch?v=hRFJJFW-XxI
....so from there, i unlocked again, reloaded CWM etc and i loaded 2.3.4 flashable zip (found in the forums) via CWM.
and voila..battery life AMAZING....after 8hours im usually still at 85%...by evening time after using the phone all day im still at about 60%
from here do what you want with roms..
i loaded the alien rom without adding the themes..and the battery life is as stated above..
so if you are having issues try hard resetting the phone then re unlocking the BL and upgrading via cwm to 2.3.4
my battery life i back to amazing.....
p.s. would be great if someone else who is having issues tried this and reported back as well...
p.s. this worked for me but i am not responsible if you mess up your phone!
Erm..
Ok Ill bite >,>
Where are these camera buttons your referring to in this guide of yours Atrix has three hard buttons and four soft buttons power, vol- and vol+ and menu home back and search.... you hard mod a camera button into this already packed phone Ill like to hear it XP
Interesting..
Couple of q's:
- which camera button?
- unlock bootloader again? Once unlocked it stays unlocked.
- I don't understand how doing a reset leads you to unlocking the bootloader again?

it doesn't actually re-lock the bootloader. The BootLogo is replaced with the stock logo, which does NOT include the "UNLOCKED" in the upper left hand corner
sorry i didnt realize that..so skip this step for anyone that is going to try it...

well dont have the old recovery and even if i did cant read the things at all quality is very bad
me too really can't understand it properly, i need to get back that battery time, but How? can anyone else explain it Please?
Anyone except TC try this with sucess? I have Alien 4 with stock kernel and i am getting about 15 to 20 hours before death.
I could be wrong, but I'm fairly confident that the following information is correct:
Doing a factory reset on the stock android recovery simply wipes data, cache, and dalvik - all of which can be done with any of the after market recoveries.
I am unsure as to whether or not factory reset also wipes the battery stats in the stock android recovery.
Edit: It is highly recommended to wipe the battery stats after you install a new ROM or kernel. To do so the quick and easy way - charge the phone to 100%, reboot to recovery, clear battery, reboot. If is then recommended that you let the phone die (or at least get low) followed by a full charge 2-3 times to make the battery accurate. The most involved way to reset the battery stats is to charge to full with the phone off. When it says 100%, pull the battery, plug it back in, let it charge for an additional hour or two while still off like this. It will likely not show 100% after an hour or two, that's fine. Boot into recovery, wipe stats, start up the phone, then unplug it. Follow this will drains and full charges 2-3 times and you will be set. This helps to fix poor battery life when it is caused by a battery that will not fully charge.
OP you should try to drain the battery down to nothing. A lot of people who screw up their battery stats end up with bad battery, however at times you can get a very slow draining batter that will give you 20 hours with 60% left, and then when the phone hits 53% (random example), the battery will fall from there to dead in just a few minutes. This happened to me when I first flashed Ninja SF. I was amazed the battery until I decided to let the phone actually die.

Well im on Cm7 so far only 48% left after 18 hours of moderate use

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!

Howdy, everyone!
I have a problem with my G935F: the battery percentage stays stuck while the device is on, it gets updated on reboot but then won't change. If I connect the phone to the charger the icon in the status bar reflects that but the charge level still won't update until the next reboot.
Battery life is great and charging while the phone is off shows the correct percentage throughout, which makes me believe this is not a problem with the battery.
The phone is rooted and I'm on stock 6.0.1. I've already tried multiple full wipes and flashing several versions of the stock rom (including Nougat) but the problem persists. I've also tried clearing the cache and the dalvik cache to no avail.
Do you have any ideas about what the problem might be or what steps I may take to try and fix it? I'd like to rule out all possibilities before dishing out €50 to have the battery replaced!
Maybe you have an app that's interfering with the reported battery level. Does the battery indicator update properly when you boot the phone into safe mode?
Unfortunately, no.
No ideas?
Unfortunately the battery level is still incorrect even when the phone is booted in Safe Mode. However it is correct when the phone is charged while turned off and the battery life is normal, which makes me believe it's not a hardware problem...
Hey guys sorry to bump old thread , but found this thread and its good to not always make new threads Well, i also suffer some heating issues but recently my battery percentage stuck at 82% while i was charging with hotspot active , i dont know why it got stuck , but when i replugged the jack in usb port , it continues but after sometime stucks again at 84% , i cleared cache partition but its still the same. But if i turn off the phone and charge, it will proceed to 100% , so the only changes that i made in system are enabling developer options and installing nova launcher and xwidgets app , phone is not rooted and completely stock. Any hints guys ?
