Sounds to me like dead battery. If still under guarantee: unroot, delete triangle, flash stock rom and bring it to service. Othervice just bring it to the service.

Re calibrate your battery stats by using zepplinrox's die hard battery calibrator (it's a scipt, search on google):good:

It is useless, batt stat gets written after each recharging. Wiping battery stats is even removed from recent CWM recovery as it brings nothing.

Just fully recharge your battery (put it under charged for 4 hrs).After fully charged unplug the charger and wipe battery stats directly or using the script,:thumbup:
I udid the same way before and worked good

Battery calibration

I think there is some problem with my battery stats, The battery level randomly drops by some 15 % in two hours when the phone is not even in use!. Think its because i flashed too many roms...
I researched and found out that recalibrating the battery would help. I have to charge till 100%, go into recovery , wipe battery stats and then let the phone die, And again charge till 100% then let it die again.
Is there a simpler way to do it and the Nexus never charges till 100%, So what am i supposed to do?
Wipe battery stats when the nexus says its fully charged?.'
Can someone help me with the exact steps?
Thanks in advance!

I am assuming that you have root since you said you're a flashaholic. Download Battery Calibration from the market and that should simplify the task.
Not all roms show 1% battery discharge. And flashing roms day in day out doesn't allow the roms and your battery to get acquainted with each other. After calibrating your battery, allow it to settle.
Thank me later.

Nexus S never charges till 100%. So i should calibrate when it says "Fully charged" right?

[Q] Huge Battery Drain on Reboot

Hello Folks,
I m facing a wierd prob on my device from last 3 days and its about my battery. its not about how frequently my battery is Draining. When i charged my Mobile fully to 100% and Reboot the device , after reboot the Battery comes to 93%. same when my device was on 35% and after reboot it came down to 3% WTF.
I thought its battery callibaration prob. i was on DDLF2 when this prob occured so i made Full Flash using XXKPE--> XXKPQ. But still prob Persisted. Then i used a app Called Battery Callibration From market By "Nema" and follow the Procedures as mentioned by app to callibrate my battery. bt still the prob persist.
one more thing , after doing 100% charge the app showed battery has 4185 mV of charge and After the reboot the perc. came down to 93% then app showed the battery still had 4122 mV but with 93%.
im currently on Stock XXKPQ
I'm having this problem aswell. Don't you worry, its quite offten appear after flashing. Use your phone as usual ant and your battery stats get normal after couple weeks. Don't do any calibrations, android does it by himself.

Thanks mate , i will try it and post feedback after a week
Charge to 100%, drain to 5-10%, charge to 100%. Repeat a few times. This is battery calibration, the app does not work.
I feel battery calibration is most rediculous method that android users have to do. A dumb nokia 3310 can show us accurate battery indicator even if we reboot it 100 times.
Google developers really have to concentrate on this battery part.

I also have the same problem
If you use your device with no flashing whatsoever, it will always show right battery stats, you can't flash your damn nokia 3310
I too have the same problem.Looking for a remedy.

It is normal for a newly flashed ROM. I always had 20% drain after reboot after new flashes. It's normal if:
1. Newly flashed rom - let the android calibrates itself.
2. Fully charged battery which was left attached to the power source for sometime. Battery discharges itself quietly despite it showing 100%.

Probably you need a new battery...there's a limit to how many charges...happened to me, my battery was no more than 12 months old...try this..charge with the phone on till 100%, then shut down the phone, charge with phone off till 100%..switch on the phone and if you do not get 100%, repeat the process until you have 100%...
me too, when my phone fully recharge (showing 100%),I reboot it. after I reboot it shows 92%

[Q] when i reboot my phone i get false battery readings!

Ok, here is the thing when i have 70% battery percentage and i reboot my phone when it boot up the battery drop to 1% sometimes to 14% someone knows how to fix this??
Bro your supposed to put this in the nexus 4 android development. Not in here
And not even in Development, but rather in Q&A, Help & Troubleshooting. Countdown to a moderator doing just that for him.
What if it has nothing to do with a nexus 4 my phone does that sometimes too, basically download battery calibration from market charge your phone to full hit calibrate then let the phone fully die then charge it to full uninterrupted.... It solves it most the time....I have to do it a lot I have 4 batteries and a extended battery so every time I switch I have to recalibrate

How to Wipe Battery Stats On Nexus S

Hello guyz,
I want to wipe battery stats of my nexus s but there is no option like that in cwm>Advance>Battery Wipe Stats
Can anybody help me in this?Thx
don't ... it's quite useless
( there are tons of app,but u can also charge to 100% and battery stats are deleted automatically, or pull out battery, anyway it doesn't affect battery life ... )
Yeah as the last poster said, a Google person came out and busted the myth that wiping battery stats helps in batterylife/precise readings. The stats wipe on their own after each cycle, I don't know exactly how long those cycles are but most likely after full charges/a day or two etc.
Its best to just let it be and it will calibrate itself.
But if you really want to the batterystats.bin file is located in the system or data folder in the root directory, delete it and it will automatically start a new one.
I wan to wipe battery stats of my nexus s bcaz it's not fully charging to 100% Only charging to 98% and saying fully charged.Today i have flashed a new rom and now it's charging to only 95%.What the heck problem it is

Some ROMs have a ceiling for charging the battery in order to 'preserve the battery' so it doesn't completely die as fast. So they make it so that it can't charge all the way to 100%
So its not an actual problem on your phone and wiping stats won't help you
However if you still want to be able to charge to 100% you can download nstools which has an option to fully charge

Ok guyz thx for ur post and ur time.
Batterystats is nonsense. Batterystats are wiped every time you charge your phone to full or almost full. It makes no sense to wipe battery stats with an app. Fully charging your phone and letting it turn itself off because its empty works best!
Me Gusta!
I used an app called battery calibration..

Discharge your battery completely. Recharge it to 100% without breaks and without turning it on. Dont remove the charge, turn on the phone now. After you see lockscreen, diconnect the charger and you'll be fine
