[Q] Battery calibration? (Power off at ~11%)

My HTC Desire consistently executes "power off/shutdown" at 11% battery (which then states 0% on a reboot).
Device is about 9-10mths old and I run the battery down daily.
How can one recalibrate the battery meter?
Any chance HTC/Telstra would replace battery under warranty (if this is a battery issue)?

Issue persists after wiping battery stats in ClockworkMod Recovery 3.0.0.5 (fake flash method).
11% today, but it actually shut down at 15% last night.

Hello, I have the same problem. Does someone know how to calibrate the battery (wipe battery stats doesn't fix it).

hi,
look to this thread, there is also an app so called in the market

[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...

First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next

And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.

you might want to try a new radio too

same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????

I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(

Yeah this is no fun...

battery drain problem try various way with no result please help

yesterday i flash my rom from clean GB to sleeper rom EL30 without wiping but it stuck in samsung logo so i flash it again to stock EC05 without wiping dalvik chace(wiped chace etc) using recovery menu
after that my battery draining fast about 1% every 5 minute , and this day i do some search about calibrating the battery with various way such battery calibration from market and some charge to full and wipe battery stat but my battery still draining fast
my question is,is it possible flashing rom without wipe davilk chace will make some problem like this?
i monitor it with battery monitor widget pro,when idle it eat 121-500ma is like something in background process and the temp is 31c(this temp is like playing 3D game on my epic before) is like something heavy running in background
i try various method and do flashing again with wipe everything exc dalvik chace from CWM purple edition but the problem is still there , is flashing using odin back to stock EC05 will fix this? or try flashing rom again using rom manager? with wipe chace and dalvik checked? please help i never get this problem before

after some research when i in plane mode with account and sync(auto sync turned off) batter temp drop to 26c(normal) but battery drain still there...when i turn off airplane mode battery temp going up again(31c) so is it possible there's some error in android system that drained my battery because i dont wipe dalvik chace? i will try wipe dalvik chace after charge my battery to full

Wow that was a mouth full.... where are you from so I know if read in the right accent* not trying to b mean* just makes more sense to me in accent =/
As for the battery problem you should have wiped davlik yes, but I don't think that's what's causing the drain you should find betterbatterystats and see if that will help shed any light on what app is using you data in the background. Also go into running services and stop whatever you can/ don't need.

i think my problem solved now, here some conclusion and step to fix the problem for people who get this problem too in the future :
just charge it 3 hour straight even when led indicator changing to blue after that follow battery recalibration guide on cyanogen mod wiki
my mistake was wipe battery stat after battery indicator changing to blue,this is not accurate bc battery indicator still based on wrong battery stat and even tough the led indicator changing to blue the battery power was still below 100%
my normal temp for epic 4g was 24-26c and when playing 3D game/heavy app 31c and eat 2ma in idle mode(on battery monitor pro widget)

[Q] Battery stats NOT resetting after charge

Hi there.
After a day of usage with the purpose of testing Greenify benefits, my battery usage does not reset after putting it on charge or reboot.
What i've tried for fixing:
Disconnect the battery from the phone.
Using a different battery - Different percentage but same usage time.
Wiped cache and dalvik cache.
Performed a fix permissions.
Deleted batterystats.bin from /data/system - For strange reason i no longer have "wipe battery stats" on CWM recovery.​
I am using AK Kernel (Pirates) but when i first discovered that battery issue i was using AK Kernel (Purity) - So i assume it's not the kernel?
Trickster MOD: Stock settings.
ROM: Paranoid Android 3+ 4.2.2
So, as i said before, the only new App i installed before that issue was Greenify, but i hardly doubt it's its fault.
Any suggestions before i perform a factory reset?
Meanwhile i'll see what happens once i disconnect the phone after a full charge.

R: [Q] Battery stats NOT resetting after charge
Update: a full charge actually resets battery stats, but not anymore on partial charge/reboot/battery remove.
