OMG Battery stats... - Nexus S General

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

Wipe battery stats

will that help with the full charged at 95 problem?
...
If you mean wiping the stats under battery usage, then no. They get reset at each charge. I don't know of a solution to the apparently incomplete charging. Sometimes mine gets up to 96, other times to 100...who knows?
-Rob
I have that problem too. Another problem ive been having lately is when i reboot my phone, the battery comes back at abour 40% lower. Its happened a few times where i reboot and have plenty of battery, and when it comes back its at 5%. After a few more reboots it will be back to where it should be.
So on a rooted phone in clockwork recovery, what does the 'reset battery statistics' option do?

Fix for poor battery life on dj05/dl09 (rooted)

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.
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.

Battery Issues SOLVED!- New Solution...after I tried many..this works!

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?

updated the hard reset instructions to reference a youtube video (not mine but describes how to do it)

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.

[Q] bad battery life on my hero

Hey guys, i have a problem concerning the battery life of my HTC Hero with FroydVillain 1.7.3 (Android v2.2.1)
In the last couple of days my battery goes down by 10-12% per hour without even touching the phone. I tried factory reset, wiped sd card and reflashed, flashed CM7 but still the battery issue didn't go away.
I charge it 100% before i go to bed at 11.30 and when i wake up at 7 the phone is completely powered off..
The thing that consumes my battery is the process "Android OS". I read about it on the internet, but all threads were SGS2..
The strange thing is that it's CPU usage time according to the battery stats is 1h 21m after 3 hours of sleep.. Is this normal??
I have everything turned off - wifi, gps, mobile data, auto sync, background sync and still the drain continues.
Has anyone had this kind of issues and possibly a solution?
Or should i buy a new battery?

I have also been experiencing battery issues with Froyd lately, but not to the same degree as you are. My solution was to wipe and install another 2.2.1 based ROM. This new ROM is acting normally in terms of battery life.
With Froyd, my battery was acting "weird" in terms of overall battery life. Once I got about 3 good discharge / charge cycles in a row things seemed to improve.
Another thing to consider is did you recently install any new apps? Some apps don't play nice and cause the phone to not enter sleep state OR cause excess CPU usage.
Some people might say "wipe battery stats" but some Google Engineer / Developer has recently dispelled that myth... https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
Good luck!
It's not from any app. Last night i wiped my sd card, wiped everything from recovery and flashed Froyd. I used it all day without installing anything besided battery graph to monitor my battery usage. it's something from the OS itself i guess..
The funny thing is that it seems that in the past two hours the drain has disappeared and now the battery is reducing by ~1% per hour and i haven't done anything during that time, except 2 calls under a minute each and 1 sms.
How old is ur battery? Did you consider that it might be physically related? Not because of the processes or so?
One more thing I noticed - if I charge by ac outlet, it charges faster, and lasts longer, if I charge by computer usb port, it charges really slowly and battery drains way faster... I don't know about battery life, maybe from ac outlet it dies faster, but 2 years of using it and still 1.5 day of normal use...
Thanks for the replies guys! I found the problem, it was my radio.
I flashed the latest radio and now my hero's battery life is better than before!

Looks like you have a battery problem. OS does not really kill batteries, you can see more or less the same performance if there are no background apps eating your power.
Check these batteries for your Hero. These are top quality and many users vouch for them.

Y u no sleep? help me, thanks.

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.

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.

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.
