battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?

It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

well after the screen 40% we have android OS @ lower 30%

Do you have an SD-Card in?
I was getting the same battery life, took out my SD-Card, and I'm getting 7 hours on screen time with stock battery.

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.

GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.

It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....

Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing

Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.

Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.

Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?

i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

[Q] Battery self drains in night even in sleep mode

Hi, In my apparently new Note II N7100 (Just a few months old).
I have started noticing my battery life is getting worse.
Multiple issues ;-
1) Battery self drains even when I put my phone in Sleep mode. If it was 60% at 10:00pm , it reduces to 10% in the morning by 6:00am
2) It is taking hours (almost 12 hours) to get it charged to 100%.
3) Even like unlocking phone and even opening a call log can eat upto 1% of battery.
Can anyone help please.

[Q] Why Battery Draining Fast?

I have owned this phone for about 3 days, but I have some battery issues.
I attached 3 pictures, and on the first picture, you can see there appears to be no wakelocks, but on the 2nd picture, the Android OS used the vast majority of my battery life, and the 3rd picture, Android System has a lot of "Wake Up Device" (i don't know what the number means is it minutes?)..
I have uninstalled/disabled most of the apps I don't need, and have the brightness set to low, and on airplane mode with all sync off, and zenmotion turned off, and this still happens. I lost about 11% battery overnight with this problem. It seems like when I am using the device, the battery drops a percent every minute even when I am just scrolling through the Settings.
I only used about 1 hour screentime on this phone and the rest on idle.
I already installed both system updates.
Does anyone know why this happens? I know there is a memory leak problem, but I saw on another thread other people don't have that bad of a drain anymore...

Battery drain issue still not fixed with updates???

Disable PC Link and Party Link default apps, worked for me. They're default apps using cpu all the time like they're SO Android... Disable all default apps that you don't use too

I've got here two brand new models, which differ only for touch and battery version (Z2C3 01040005 1525 and ... 1526)
The 1526 doesn't show any drain. The 1525 does, as of its very first boot. I tried keeping same settings of course.
I'd like to point out that when connected and charging it shows big steps like going from 63 to 72% and it also reaches 100% in less than 60 mins.
When disconnected the discharge path exhibits about 1:15min of operation.
May I suspect the battery is defective?
PS: after a factory reset from recovery seems have fixed the problem for now at least...

When you tilt your phone app icon adjust to the tilt, yes looks cool until you realize how much battery you could save by leaving then static and not constantly running a fDucking tilt sensor.

Heavy Battery drain from Android System after upgrading to OOS 4.1.0

After upgrading to OOS 4.1.0 over OTA my Android System usage started to drain the battery. So i downloaded the full zip and did a complete clean flash of OOS 4.1.0. Even after that the Android System Usage is draining the battery. I'm attaching the screenshots. Any solutions to this ?

Clear Googleplay services cache and app data, then reboot.
Haven't tried it myself, though i have read it has helped many

Settings / apps / Google play services / manage data ( clear data )
Settings / backup and reset ( turn off backup )
Settings / battery , click the three dots at the top and check the power hungry apps and enable aggressive doze and whilst in aggressive doze settings turn on nearly all of the optimised apps just don't optimise things like phone , messenger , WhatsApp if you use them regularly ...
Hope this helps and if it does then please hit that thumbs up button it means the world to me....

are you rooted ?

This is probably not because of Google Play Services.
Can you share screenshot of "Android OS" battery usage as well? I bet it has keep awake time over 1.5hrs.

Snap. I have the same problem here too. Only thing I haven't tried was switching backup off, but I really don't want to live without it, it's just too useful now.

My battery drains even when the phones not in use. I had great battery time at the start (6 months ago) but now it hardly lasts for 20 hours with normal use. Wonder what they did with the OS or maybe its cheap manufacturing

**** OOS... I littery Switched to VertexOS for this reason and I don't see a difference other then Vertex being way more peformant and batfery friendly.

Yeah, happens me every week after a clean install despite all the play services data delete, cache, etc. Always ends up like this. Hopes it gets fixed, Nougat hasn't been going well on our OP3

Me too, heavy draining even when I don't use my phone ?
