Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

+1 that app will tell you exactly what's bogging down your cpu, and which apps prevent proper deep sleep mode.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.
Since I can't put my signature for unknown reasons...(Maybe because I just created an account since I did not want my old one)

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!

[Q] Battery defect or rom issue?

Hello!
Sorry I can't post this in the Paranoid Android thread yet. As a noob I can't post in that forum until I have 10 posts so I'm at a loss as to where I should post this.
Anyway, I just put the new 2.1799 PA ROM on my Nexus 7. Unfortunately, I seem to have a serious battery drain when the screen is on. I have read many posts where people claim to have easily achieved 6+ hours of active screen time per battery charge whereas I'm only getting 3-4 hours of active screen time per charge, almost all of it related to web surfing. I have a strong wifi signal and I keep my screen brightness around 20/30 range. I'm not sure if it's the ROM or if my battery is defective.
I have also read about a battery calibration app through a different thread. Is that necessary for the PA ROM? I didn't see anything in the tutorial mentioning a battery calibration.
Included are two pictures, although they aren't very indicative of my problem as my tablet was sitting in my backpack for most the day.
Please tell me I'm just being paranoid! Thank you for the help!

The battery recalibration is a myth, but there is also no harm in trying it.
according to the pics you have attached, there doesn't seem to be anything wrong.
Battery also drains faster if you have too many apps that have services running.
Ex: Facebook.

I know there is a battery warranty, but how bad does it have to be to get it replaced? My battery cannot reach the 9.5hrs of 720p video playback (with headphones in) as achieved by Asus. I can only get 8hrs. From normal usage, I am only able to get 6 hours.

The ROM has less to do with the battery than the kernel does.
I would say try flashing another kernel. The default cyanogenmod kernel that comes with Paranoid Android didn't give me very good battery life.
Franco kernel gives me excellent battery life. Other good ones for battery are Faux or Motley.

That is in the normal range i would say, Companies usually exaggerate.
As suggested try franco's kernel.
He has a free kernel flashing app on the play store.

My issue is with how the battery percentage is running down......
Charge the N7 to max and use it for a good 2 hours and the battery STILL reads 100%.
Even if I then shut down and reboot it still shows 100%, then all of a sudden it will start to drop very slowly at first until it gets to around 40% which it then shuts down and will not reboot, obviously void of any battery cells.
Clearly it's a calibration issue.
This is on a stock non-rooted machine.

I tried his kernal. I did my video play back test and I got the same 8 hours as before. During normal usage I think I will get about 30-40 more minutes. Still not what others are getting

Try a factory reset. If that doesn't work, you're more than likely actually looking at it being a hardware issue.

Factory reset was the very first thing I tried when it started playing up.... I'm hoping when 4.1.2 rolls out it may clear it. If not then I'll have to look at doing a root and access the battery file to see if deleting may help.
Thing is a recharge should clear out the battery file stats and calibrate, which clearly it's not.
Apart from this the N7 is flawless so it's staying with me. Running hours is the same, just doesn't give an accurate reading of how the battery is running down.
It's not a big issue.... to be honest I'm more curious than annoyed.

Have you tried installing a 3rd party battery app to see if it registers the correct battery output? This is the one I have used, works good. GL

You do realize that wiping batterystats.bin has absolutely nothing to do with the battery fuel gauge, right? It does not "calibrate" the battery or affect reported charge. The myth of wiping battery stats has long since been debunked by Google's Android engineers. The only info contained in the file is a list of apps that used battery since the last full charge.
The only other thing you could do besides a factory reset is see if 4.1.2 fixes it for you. If not, then it's definitely hardware causing the issue- the battery charge is likely being improperly read and reported by the battery itself.

[Q] How to improve Nexus 4 battery life?

Hi all,
I've been having problems recently with my phone not having good battery life. Although, I don't even think I've ever noticed good battery life recorded for it.
At this point in time, I'm struggling to get to 2 hours screen on time, with as the screenshots below showing at I'm at 20% with 1 hour 45 screen on time. I've seen screenshots of people recording at least 4 hours screen on time, yet that doesn't seem to be the case for my specific phone.
I've tried Franco's kernel's and I've still not noticed a difference in the battery life, it still seems to hover around 2 hours screen on time. Checking the wakelocks with the wakelock detector app, and it shows that my device doesn't seem to sleep as much as it should.
Does anyone have any ideas on what I can do to stop these wakelocks? And/or improve my battery life? I'm currently doing everything you would expect (of the basic recommendations)
I'd greatly appreciate the help if someone knows what the issue is, or has had similar issues.
Thanks!

1.You can try undervolting.
2.Use Greenify to hibernate apps like facebook.
3.Calibrate your battery by draining it completly then charging it to 100% in one run, so no disconnecting from charger.
Good luck!

Clearly in your screenshot Google Services is keeping awake your phone. Solution here:
http://forum.xda-developers.com/showthread.php?t=2385843
You can ask for help there. Also, for more battery life, try to UV and UC. I recommend Matrix kernel for excellent battery life. You don´t even have to tweak it, it already comes tweaked with perfect values by default.

It is not compatible with PA, because PA changed to JW branch on latest update. For now, I think that Franco is the only working.
:silly:

try different rom ?
test it for few days see if that solves anything.
go with any jss rom and matrix kernel. its the best combo for very long battery life.

Battery drain question with Android 4.3

Good evening,
I have read all over that people are complaining about the horrible battery drain and I would be one of them. If I am lucky I will get 12 hours from a battery while at work (metal building with mediocre reception) and 18 hours while outside without any reception problems.
I have been suspecting that an app is running in the background that could be causing the battery drain but I haven't been able to find it. So, I am wondering if I can get some help in finding what might be running to make the battery life a little bit better. Attached are screenshots.
Thank you.

Thought 12 - 18 hours would be a decent time to have on 4.3?
It's more than likely Google Now running in the background so you should try turning that off

Same problem
Hello,
I have exactly the same problem. I did install GE rom on my galaxy s4 for few days. I am a little a "newbi" in this kind of things. Even I spend my afternoon on the forum to find an answer, I am not able to know what I have to do now.
Briefly, here are my stats :
On battery : 8h7m
Screen on : 3h9m
Remain : 5 %
I publish herewith the resume of BetterBatteryStats. If anyone can "interpret" that and tell me if there is something wrong, that would be great !

I checked and Google Now has been turned off. I also have had Google Maps location reporting turned off (read that might drain the battery).

Using cyanogenmod provides me around 1 and a half days. .... but I usually have to kill all Google services ...

Using Easy Battery Saver on Intelligent Mode I can get about a day or more use, mimimal though, and still have at least 50% battery left.

Good evening,
I have tried running it with the settings suggested and it has not made much of a difference. I took my phone off of change at 5:15 this morning and I am now getting a low battery warning.
Attached are screenshots from Battery Status Plus. Is there anything else I can do?
Thanks.

Use wakelock detector, that app you are using gives very little useful information

If you have rooted device I suggest to Install "Greenify" app. it close (hibernate) all unused apps when your device is idle (standby)

+1 for Greenify. it really works

Hi,
do you have only battery drains or also random reboots?
the fact is that samsung shipped out a bad serie of batteries (which is confirmed by Samsung) their serial starts with BD
the symptoms of a bad battery are:
Huge battery drain
random reboots
while rebooting the phone hangs at samsungs logo
battery is swelling
phone shutting down while you have an incomming call/sms
when you are the "lucky one" to experience one of the above symptoms please replace your battery asap under warranty
if you don't do this you risk a phone exploding in the pocket of your pants this is not only painfull for your phone but also for "everything else" whats in there

A lot of screenshot but almost no info about battery drains (some info of data ussage, som apps consuption, etc, but nothing relevant)... It would be great if you could post screenshots of
1) settings->more->battery
2) settings->more->battery->touch the little graph
3) settings->more->battery->screen
4) any screenshot for partial wakelocks in better battery stats or that program you are using
First three screenshots are the most important and everyone should post them when a drain problem exists (no needed any third battery management app)

Hello! Please Heeeelp!

Help, Since couple days ago my phone's battery its draining so fast.... Worst of all, in sleep mode. With the screen Turn Off (23:00hrs to 07:00hrs) the loss charge from 90% to 15%....
I've install Custom Rom, Arvanasoft, Xiaomi.eu, Chinese beta, MiuiPro.... carbon, Paranoid, RR...etc. I've already flashed different Firmwares (right now 7.11.2)...., Recovery's.... and Right now I am on Stable Global MIUI8 8.5.4.0.... and Still Battery draining.
I checked battery status on menu *#*#4636#*#* and everything its ok. Battery Status:Good. Battery Scale 100.... Temperature: 37.2C.....
I dont Know what more to do, my priority and the reason I choose this phone overall was the Battery.
Please, if the problem it's the battery I am ok, I just buy another, but everything look good...
Please HELP!
