And I thought it was battery drain

After flashing Ics my battery couldn't seem to stay high so one day, I took the liberty of finishing the battery and...

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

Low battery life

For the past few weeks i've been noticing a bigger drain of battery than the usual and i don't seem to be figuring out what's going on...
If someone knows any way to increase battery life feel free to post any solution. Thanks in advance

have you been fully charging and fully discharging your phone?

What app did you install? Did you install a new rom? what rom are you on? My guess would be a rouge app. Have a look in the battery usage graph or get spareparts and look at the things that are keeping the phone awake.

I would suggest you download CPU Spy to see if an application is preventing your phone from entering deep sleep mode, for example. You may have a lot of widgets refreshing way too often, as well.

The only widget that refreshs at my home screen is SetCPU, in order to monitor the Temperature, but i will try that app in order to check whats going on thanks.

Ok finally I've managed to see what was the problem that was causing such battery drain/loss... The problem is that i wasnt full charging/discharging, now the battery seems to be working fine. Also I've check cpuspy and nothing is interferindo with the deep sleep.. Thanks for the help

Never fully discharge Li-ion batteries.

But is not fully discharging, under %15 damages battery? And also i put from batter over %95 because after %100, it waits until it drops and again charges if i forget there.

Calibrate the battery by running it down to 0% and charge it fully.
You can also root the phone and flash a custom kernel that offers great battery life.
Other things you can do...
Turn off sync, turn off GPS, turn off Google now, and lower brightness level to a minimum.

Yeah i was more talking about calibration. Is Just one discharge cycle enough ?
Sent from my Blade S using xda app-developers app

There's no such thing as battery calibration. Just use your phone normally, charging it when you want to.

Don't calibrate now.. your phone will already have the best calibrated battery settings.
Calibrate when you flash a custom Rom and that too,if you face battery problems. Otherwise no need. You'll do more damage otherwise. No need to calibrate if you flash a kernel over stock either.

You dont calibrate li ion battery.

And you should never purposely run it down to 0%.

It is a bit of a misnomer as the phone is calibrating the battery scale to match the discharge of the battery. It isn't that there is no such thing, it just isn't what people think.

Get the latest Franco kernel on it. That is all.

Nexus 7 shutting down in idle state due to battery drain!

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...

[Help] Battery Drain Problem

Hi All,
Everything was ok till the day before yesterday. But suddenly from yesterday I am facing a huge battery drain problem i.e. 1% per minute on my S4. I am running the latest version of Arrow Rom.
I did format everything and reinstall Arrow Rom but no luck. Then I restored my previous Stock CWM backup and again problem is same.
One more thing my phone's battery is taking too much time to full charge. It takes 5 to 6 minutes to charge 1%. Sometimes it takes more than that.Although my phone is only one year old. When Iam using phone for browsing or chatting with charger plugged in its not charging properly its decreasing.
Can anybody tell me what is the problem?

Your battery is more likely to be uncalibrated. Download Battery Calibration from Google Play and follow the steps on how to calibrate it. It requires ROOT. Any other things that can cause this are wakelocks, be careful what kernel you use. You can monitor wakelocks using Wakelock Detector from Google Play.

Or your battery might be a faulty one, check if its swollen

How old is the battery?? Over one year? Buy new one.
Or try to use Wakelock detector and after results use Greenify

Use power saving mode install stock rom
Auto brightness
Format sd card
Remove unnessesary apps
Stop all unusual apps like google plus hangout and play books etc etc those you don't use.
Disable chrome use dolfin or other's.
If you are using custom kernel or mods like audio mod or performance mods don't use them.
Auto sync off when not needed
If these steps don't work then change the battery
For charging use 2amp charger with a 16amp socket
Use stock usb
Clean your battery's copper area with petrol and also clean your
Usb cable and ports sockets
Hope this will help
And I know my English is not good.
