Hi,
So after I got the 4.3 update, I've noticed quick battery drain, around 60% batter drain in simple 8 hours, which was pretty much annoying.
So what I tried to do was these:
-Make sure the battery is at 0%
-Charge the phone using a Lower Voltage Power Adapter, this way it must drain the battery faster. Make sure it charges and says 100%.
-Make sure the battery is at 0% again.
-Charge using the normal Charger, now you'll notice that the battery life has improved.
Now you have normal battery life.
(this method needs root)
-get titanium backup or anything that can modify system files.
-search for the settings file (that is usually 4.5MB of data)
-Clear its data
Now you have resetted your data and the battery life has improved.
I don't know why these work, but after I've done them both at the same time, I now get around 9% battery decrease during the timing of the night to the morning.

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
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.
I'm not sure if it's more appropriate to post here
or on the custom ROM forum itself, but here's my battery issue:
Issue: Abnormally fast battery drain. My battery would
be fully charged, and almost immediately start draining until
it'd show 1% within 2 hrs. Screen would be off mostly (normal
use).
Been on a custom ROM since January 2017 (crDroid) and have had no problems with it since,
except 3 days ago, when the problem first appeared.
Things that are ON: LTE data (or Wi-fi), Auto apps update on
Google Play Store (never been problematic before), Location,
Things that are OFF: Bluetooth, ScreenCast, Caffeine
When I check Battery in Settings, the numbers don't add up.
I'd have battery indicator at 70% for example, but Screen,
Android System, all other apps would add up to only 7%. So
that's a whopping 23% unaccounted for.
But here's the weird thing: it drains fast until 1%, then at 1%,
the phone is supposed to initiate automatic shutdown like it has before.
When this issue cropped up, the phone keeps going for about 6 hours
or so before shutdown is started. Checking Kernel Adiutor occasionally,
I'd see a much slower decrease in voltage which probably reflects
more accurately the power drawdown situation.
Things I've done:
-clear cache (both through File Explorer and TWRP Recovery)
-clear batterystats.bin
-calibrate battery after full charge/discharge (via Root Essentials,
which basically does the same thing as manually deleting batterystat.bin,
if I'm not mistaken)
-Resetting App Preferences via Setting/Battery
None of the above has worked. Any idea what might be wrong?
My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.
OK, I've flashed 3 other ROMs: Citrus-CAF, NucleaROM and stock, and the problem persists.
By doing the above, I've crossed out the possibility of it being the ROM. Neither is it the battery
itself, because it would've shut down by itself at 1%, yet at 1% I can last 6 or 7 hours of light use.
Anyone out there have any idea?
