Since I upgraded tp 4.0.4 my battery life has been completely terrible (nexus s GSM, stock, latest glados kernel) even though I don't use it the entire day, it drains over half in about 4 hours. Anyone have any idea what I can do to fix this? It was perfectly fine before the update and would last days if I didn't use it, and about 12 hours if I did. Right now it's just unusable.
BetterBatteryStats and/or a fresh install (data/factory reset, format /system, optionally format /boot, install ROM).

Are you using a custom ROM?
I've had the same problem when I was in stock 4.0.3, which is why I decided to root my phone and resort to custom ROM's and kernels. Now my phone is doing ok in the battery department and is also much more snappier and smoother. Oh and most custom ROM's are already using 4.0.4 anyway.
Let's try and be scientific about your problem, here are some things you may want to try out first to improve battery life:
turn off wifi when not in use
turn off automatic syncing if you don't need it
set your network mode to 2G only if you're not using the internet
turn off mobile data when not browsing/using the internet
install the watchdog lite app/widget from the Google Play store so you can monitor rogue apps that are sucking up juice
do not set your screen brightness to AUTO, but manually adjust it when you need to. you can do this either in the settings menu or thru the power control widget
This are the things I can think of off the top of my head. If this doesn't improve your battery life, even just a bit, you may have no choice but to resort to drastic measures....and go to the dark side.
Hope this helps! Cheers!
mine is okay
Batt I think it quite good on 4.0.4. I can get about 23hrs of usage. Some wifi, some 3g (fb, whatsapp, updating apps, email), some music. Stock ICS.
I had this issue after stock 4.0.4 update from 4.0.3.
I found mediaserver using more battery than it should, so I;
1) Copied all files and folders from /sdcard to PC
2) Re-format /sdcard
3) Re-store all files and folders back to /sdcard
Mediaserver process is now minimal and battery is good again
Ok thanks for the suggestions guys, reformatting my phone would be alot of effort on my part due to how much time I spent setting it up so I would like to use that as a last resort.
I installed battery stats but I can't decipher what it's saying so if someone would be as kind to explain? I took screenshots of everything in an album and I would really appreciate it if someone had a look in the album below.

Well for one, you have chunks of bad signal(red bars). That right there can kill a battery quickly. The other stuff you may be better off saving the dump file and posting it as an attachment over at the BBS thread. The guys over there are pretty informative and may be able to give you more stuff to look at to help you out.
The red bars are when I was using the underground, the battery drains just as fast overnight. I will look for that thread, thanks.
Edit: I do not stay on the underground overnight, and I have a good signal in my apartment (you can see it's fine when I arrive)

yep...a weak network signal will drain your battery a lot faster. if you're not using it to text, call or surf, or if you're just going to play games, might as well go airplane mode for a while, or at least until you get above ground where the signal is stronger.
After a good couple of hours not using the phone in a good signal area create a log and post it. Preferably get the hours just after charging.

Edit: should mention I just remembered I had it on airplane mode overnight once and it still drained.
Ok here is the dump file:

Ok nevermind just did a reformat new rom etc.
Sorry guys, but after reinstalling I am STILL getting the battery drain issue.. Was a clean install but reinstalled all my old apps and settings. from full to 28% in 5 hours with very little usage.

Please someone take a look!!!
I'll have a good look tomorrow with some suggestions. Had a fair bit on the last couple days with minimal internet access.
What ROM and Kernel are you using right now?
There are a couple of interesting details there but nothing that i can point out that will take you from 100% -> 30% in that time.
Some things to test:
-Turn phone off (noting charge), remove battery, replace battery, leave phone off overnight and turn it on in the morning, again noting the new charge
-Keep data off and see if battery is still draining / Airplane mode
-Uninstall half of your apps and see if it still happens. If not, add half of the apps you uninstalled. If so, uninstall half of the apps you have left, and so on.
-Do a clean install and try for 2 - 3 days, see if it still happens (preferably a stock ROM, preferably from fastboot images)
-Attempt going back to Gingerbread and try for 2 - 3 days (preferably a stock ROM, preferably from fastboot images)
These steps can (and should) be done pretty much in order and will rule out ALOT of possible reasons and give possible solutions some merit. Let me know how this goes.

Using latest stable cyanogenmod + tried glados and netarchy and matrix kernels, all the same result. Will try what you said, also I bought a replacement battery to see if the actual battery is faulty (weird because it used to be fine). As for the airplane mode thing I already tried that, to no avail.
edit: should add that was using stock 4.0.4 before cyanogenmod.
well,, its been a long time time i dont walk trough xda but first i wanna say HELLO to everybody here and i wanted to say that i love this phone, I SIMPLY LOVE IT, fast and smooth, the way everybody wants a phone BUT i have been experimenting problems with the battery...
i used to have my phone unpluged from a full charge at 7 AM and discharged to 20 % at 8 PM, now since i rooted my device, battery is suffering i high drain since it cant survive even 6 hours of good use
any way, in case you can give me a hand im going to give you some informaction to help you help me:
MODEL: D800 atyt
SOFTWARE: 4.4.2 20c
KERNEL: 3.4.0
ROOTED with TWR, almost all bloatware deleted, xposed installed and running with G2 xposed module, battery doctor and clean master running.
*its shows that screen is using most of the battery but its imposible since im using low brightness and 30 secs to turnd off screen
SO THEN, WHAT SHOULD I DO? FULL WIPE FROM RECOVERY. and then apps restore with root apps? DELETE SOMETHING? APP INSTALATION?
anyway, i wanna know, what about you? tips? help for battery life? AANY KIND OF HELP WILL BE THANKS FULL :good:
I'll do a clean installation using this ROM http://forum.xda-developers.com/showthread.php?t=2483043 it's basically stock but he removed all bloatware. With android phones, it is suggested to do a clean wipe every 6 months or 1 year.

Very similar here, except I don't have battery doctor or clean master. My battery life sucks. I have disabled CIQ and Google Now. I installed WakeLock Detector and I am charging to 100% tonight, unplugging it, and will check in the morning to see whats going on.

Is there a difference between clean wipe and full wipe??
So I did the following:
Stopped cIQ with "Disable Service".
Disabled Google Now
Stop location services
Set brightness to 60% Auto
Charged to 100%, reset (with the charger on), then removed the charger.
Now, I am sitting at 17.5 hours on battery with 4 hours expected time left, and 2 hours screen time. Definite improvement.
not sure about the clean and full wipe but I wouldn't do a factory reset on the phone because your system files might be broken already. Just download the ROM zip file from the internet and go to Recovery to do it.
Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.
Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.
Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.
There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...
The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.
Same problem here.... Huge Android System battery drains.
I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?
Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.
Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.
Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?
To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.
I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.
I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop
Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction
As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

Hey everyone,
It's been a while since I posted on the forum since although I wasn't overly happy with my battery life, it wasn't giving me too many problems. However the last couple of days have been a nightmare! For the record, my phone is not rooted.
I've attached some screen shots which I took on the fly, but I've been getting some really weird results from GSam. Since the 500% result I've reset the cache and the other images are what the battery is currently using.
However since its draining so fast I can barely see myself able to go anywhere without a charger!
I usually leave wifi and 4g off overnight anyway so when I woke up earlier I was surprised to see it with a 10% drain from doing absolutely nothing. I had to put it into power saving mode last night as I needed my alarm for the morning and was worried the phone would drain too quickly.
As far as I can tell the phone is sometimes entering deep sleep and sometimes not. It wasn't at all last night and isn't currently either. I really have no idea what the problem is and wanted to feel out some ideas before I factory reset the phone for the second time. I kind of wanted to avoid it if poss but am beginning to think it might be the only option. I'm also now worried there's something wrong with the battery
Any advice would be greatly appreciated!

Try debloating stock rom, use free debloater from XDA (You dont need root to use it). I've uploaded my list of debloated apps as reference, double check what You'r using and if You'r not sure what app does what try google-ing it.
You can also try disabling stock Chrome browser and install Chrome Beta (I've been using it for few years and never had any problems with it)
Also beware of disabling Samsung Store etc. as some members of XDA pointed that after disabling it, it won't work untill factory reset.
Check my previous posts, I've uploaded screenshots of my battery life with debloated rom from this list.
Does it work on Mac? I don't have a Windows computer. I've not done this sort of thing before, is it easy to do? :/
I'll look up chrome beta but I don't know if it's anything to do with that since it's pretty bad even when I'm not using anything. I wish I could tell what was rinsing my phone battery. Maybe I should attempt to root it after all.
