Last week my rooted Desire was on 25% battery and after 2 txt messages it said plug charger in and battery showed as 0% and it shutdown.
So I re-charged it while the phone was off and went into recovery and cleaned battery stays and switched it on and battery was 100%. It was fine until today then it was at 21% same thing happened.
Is my battery at fault?
did you wipe dalvik cache, partitions etc?
You need to give more info like radio, rom etc.
Use juice plotter and see what times of day the phone is losing so much charge imo.
Use batt stats and see under 'partial wake usuage'. On you keypad dial *#*#4636#*#* and goto batt history...
I had this a couple of times. Callibrating the battery fixed it.

Everything I have is stock, got the OTA 2.2 update, then rooted using unrevoked.
Since then, my battery life has been pathetic. My up time is 46 hours, and awake time is 43.5 hrs, meaning my phone's been awake for almost all the time. This is what I'm guessing is causing the battery to die so quickly, but I don't know what is causing it or how to even find out what is causing it.
How do I go about fixing this?
Thanks
Go to Settings --> About Phone --> Battery Use.
I'll bet there's one application hogging up a whole lot of %. Uninstall if you don't want it, or come and post back with what it is and we'll see what's what.
Cell standby 32%
Phone idle 29%
Android System 24%
Display 9%
Maps 4%
Internet 2%
Is what it's showing.
Try this, it improved my battery life significantly
1) Install battery left from the market
2) Charge battery completely with it powered on using wall charger
3) Leave cable plugged in
4) Reboot to bootloader and go into recovery then advanced and wipe battery stats
5) Reboot phone
6) Go into Battery Left settings and recalibrate
7) Unplug the cable
Now use it normal and see how it does.
sounds like an App problem... i would download SystemPanel by NextApp and enable monitoring to find out what it causing your problem. Once you find out just remember to disable the monitoring.
i guarantee you will get your moneys worth... i believe it's $2.99
EDIT: or you can try SpareParts... i believe it's free on the market but it doesn't go as in depth as SystemPanel.
Installed Leedroid froyo over stock rom.
Replaced the radio with recommended one.
Installed the kernel.
SET CPU= Smartass
Problem: 8-9 hours standby time. No wifi. Phone on 3g network.
New problem: Phone's screen is not getting off automatically since i updated the kernel.
Please help. It is driving me nuts. If I use gtalk for about 2 hours, battery is drained off in 5 hours.
Its a brand new phone and battery had a days back up on stock rom with conservative usage.
Was your battery at 100% when you flashed the radio? I had to recalibrate my battery after flashing a radio on my standard Desire when the battery was at about 50% as I was only getting about 6 hours standby.

Did that. The only problem am facing in this is when I achieve a green light and 100% with the phone switched on, the moment I shutdown/power off the phone to charge further, the CWM recovery console comes up with a backlight and the orange battery indicator never turns green (even after 1-2 hours).
So at orange indication only I wiped battery stats, and thereafter there was no improvement in battery life.
I would advice to wipe all (backup first of course), install the ROM again, monitor the drain with nothing installed (except battery monitor widget).
I usually do a test in flight mode (target=2mA)
then with phone ON (data ON/OFF doesn't change a lot for me) (target 3-4mA)
!!! disable all autosync !!!
If you have the same values I will say that it's ok.
Then add one by one your kernel, account sync, appli an monitor the drain (at each step).
You will find what is draining your phone.
Do not forget that the drain is subjectif. In GPS I have often more than 300mA drain!
Where do I download the battery monitor widget?
you can download it at HTC widgets for battery monitoring.
Current drain is at 250-300. That too in standby. Gps off. Wifi off. Don't know what is happening
Airplane mode it is 134
As everyone knows my battery life such a pain. Today i realised something. When the battery percentage for example %43 after doing a soft reset with pressing power button on 10 seconds when the phone starts i look at battery stats and it shows %46-47. I flashed the lastest RUU previous day and charged at nearly 5 hours at night. Except that battery drain is too weird. It drains %3-5 when screen opened.
It's just the software reporting the battery stats wrong. Seems to be some type of bug I think.
Someone plz help me out with that situation...
Hello,
I have a very annoying issue with my battery percentage. Typical scenario:
I unplug my phone at 100% after loading it overnight and perform some basic tasks, like for example reading news with Flipboard for a couple of minutes. My percentage already goes down to about 75% to 82% in about 10 minutes. Then I don't use it intensively, only to check the time or messages, so the percentage stays at almost the same amount for hours. When gaming, or performing other more intensive tasks, my percentage almost drops 1 to 2 percent/minute. I get "battery low" warnings at 14% and 4% and then it goes down all the way to 1%. Now I can just continue using my phone like before, for example for gaming, web browsing, for something between 40 minutes and 3 hours.
The issue is obvious: my battery percentage is not calibrated correctly. This has been occuring since more than half a year now. I had many different roms over the years, I can't blame it on one particular one.
Now, I read about a lot of ways to calibrate your phone, so the percentage is accurate again. I have tried a lot one of them. None had any effect. I tried the following:
- wiping battery stats (multiple times)
- completely unloading my phone (restarting it multiple times, boot into bootloader and waited until it just turned off by itself and won't turn on again) and then reloading it (via charger) without interruptions (everything multiple times)
- using the app "Battery Calibration" (deleting batterystats.bin)
- using the app "Battery Monitor Widget" (waited until it shows 0 mAh, then wiping battery stats
- some battery saver app
I also switched batteries with a phone that was purchased at almost the same date as mine (09/2011) and has not been modded in any way. My phone currently runs Jellytime 4.2 R11. I updated it this week, and also wiped battery stats during the installation process at 100% charge.
Any suggestions? Any help is appreciated! Thank you in advance

Easy!
Get a new QUALITY battery.
But maybe that was to obvious for others to respond.
Recently my N7(2013) will shut itself down when the battery is low (about 10%) without any warnings, not even the "Shutting Down" dialog that it should show whenever it shuts downs (except for the usual low batt warning when it reaches 15%). After the shutdown, I cant even turn it back on not even the screen, nor the low batt (waiting for charger) screen is showing up until I plug it into a power source the it will show the charging screen and then I can turn it on again.
Its been a few times now, not sure its a hardware or software problem though. It shouldnt shut down when it still has 10% in it right?
Attached is the screenshot of the Battery Usage that shows the battery level shots down to 0% immediately from 10%.
Nexus 7 2013, Stock, Not Rooted
Are you using a battery monitoring program (battery doctor, better battery stats, etc)? If so, look in their settings, to see if they are set to shut down @ 10%...

Nah I don't trust these apps so I don't use them. Moreover I'm did not root it so even if I use them they shouldnt have the permission to shut it down
Simple fix
It is an issue I have suffered with a couple of times and it appears we are not alone. It seems that the battery calibration is out of whack. When you charge your nexus up does it stay at 100% for quite a while? I
tried factory data resets amongst other things and nothing worked. I stumbled across a thread with a really simple fix. Turn your tablet off for 2 hours. Then turn it on again. Mine miraculously lost 26% of battery in that time (from 100% where it had been for 8 hours down to 74%). Then it started to use the battery at a normal rate. Working fine now.
