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?

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.

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.
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

So I've been flashing ICS ROM and GB ROM back and forth (sometimes 5 times a day ). I did read the post from the Google Eng about wiping battery stats not required so I never bother wiping them. Today I noticed my battery was at 30% and after a reboot it went all the way down to 10% in like 1 sec LOL. I'm like WTF! and just ignored it. Later I tried to use my phone and noticed the battery went up to 18%????? I said screw it and wiped my battery stats and everything is back to normal....
Yeah. So this is why the option to wipe battery exists. You could have plug it in and charge it all the way up and it would have reset battery stats on its own also.

thats what i said in the xda thread about it here, and in that google engineers thread on g+. but no one wanted to listen to me. i told them that it wasnt about increasing battery life but about the inaccuracy of the stats themselves. ive reboot at 53% then booted up at 7% before, then rebooted again to 46%.
exactly...I've used it to recalibrate my battery several times. I don't know where she got the idea that it was meant to extend battery life lol
Every few kernel flashes, I like to completely deplete, then one shot recharge my battery. recently, i've been noticing that while the system is showing 1-2%. upon reboot it reads ~20%. after that goes down to ~2%, the next reboot shows ~14% and so on. it takes a couple of cycles until the battery stays fully depleted.
I'd like to fix this to regain the extra battery life my phone doesn't realize it has. i remember from back in my Droid X days that CWMR could wipe battery stats. However, I've been using TWRP for quite awhile now and I haven't been following CWMR.
Is there anything I can do to fix this?
You can still wipe battery stats if you are using cwmr. I am not sure of its effective but give it a try.
I recommend to backup your data and flash stock image. That should fix it.
Always charge the phone 100% and use it till it reaches 5%. Do this for couple days.

Does anyone else have a massive battery drain in Kit Kat? I can charge my Nexus to 100% and in an hour or two it's completely dead with blinking red light. I tried restarting to bootloader when it was at 5% but it was still on for like a half hour. Once I restarted my phone, my battery read 0%. I'm thinking it may be time to change the battery if no one else is having this problem.
I suggest you to reset the battery stat from the recovery. The probability that this works are low but is better then nothing.
How do I do that from recovery?
Edit: phone was charged to 98%, rebooted into recovery to see if I could wipe stats in TWRP, rebooted again, phone reads 28%, 3 minutes later it read 66%.

To wipe battery stats in TWRP:
boot into TWRP recovery
/advanced/File Manager/
folder /data/system/
click batterystats.bin
click Delete
reboot system
If you can't see the folder, you need to mount the data folder.
Well I switched to Philz Touch, do I have to do the same thing then?

You should have the wipe battery stat under advanced in your recovery.
The right step to follow are:
1. charging the battery FULLY
2. wipe Battery Stats
3. don't charge the device until the battery still turns off your device because it empty
4. now again FULLY charge without interruption
Wiping battery stats does nothing, see here: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ . Sounds like your battery is borked. May need to send away for repair. Are you still under warranty?

Yeah I figured. Thought it was a KitKat bug at first but then it started getting ridiculous. Phone was at 70%, started taking a photosphere, phone shut off, and when I turned it back on it was at 3%.
No its not. Bought it off Craigslist. Just gonna order a battery off eBay for $18 and replace it myself, see if that fixes anything.
I just got out of a similar problem.
My battery percentage was jumping all over the place.
It would charge fully in about 5 mins, and die in about 20.
Everytime I restarted the phone, it would read a different percent.
I ended up running the phone on full brightness, with like everything turned on to drain the battery all the way down.
& Everytime it would shut off cause it had no battery left, just restart it and keep draining it until when you reboot the phone it no longer turns on(because the battery if fully drained of course).
That's when it is really dead.
Then just charge it to 100%, and keep it charging for about 20 extra minutes once it hits 100%, and now it's back to normal!

That really worked? Any problems with it since and is this a common issue with the N4? For some reason it won't die when it's in the bootloader even though the percentage read 5.
So yesterday it was so dead that it gave me the red blinking light, should I charge it when that happens again and should I leave it off while charging it or turn it on and not touch it?
How many times did you have to do this until it straightened itself out?

I am currently having WakeLock problems, but I do not beleive this was the cause.
I was able to restart it after it died about 4-6 times, till it was fully dead.
Then I charged the phone, and kept it off the whole time.
I installed wakelock detector to make sure that wasn't the problem. I had this problem on the stock rom even before I rooted. So the problem hasn't persisted since?
