Solution: 2nd post!

I DID IT !
almost in the same time it drained almost all the battery before, now it has lost only 1% or 2%!!!!
after reading every single post on the internet (many thanks to who has investigated battery drainage), i've mixed the tips and tricks and what i did is:
(Maybe a lot of things are unnecesary)
- Disable syncing in gmail account (everything)
- delete software update's cache
- killed all services except only 2 first party services: SNS and Google services
- Tweaked the apps running on startup with "Autostarts" app.
- 3g off
- Wifi off
- BT off
and, as you can see, it's completely idle. it stayed like two hours without losing battery, constantly at 71%.
I hope this is helpful! I will try to discover slowly which one of these things drains so much battery!

it looks to me that to solve your problem you transformed your phone into a nokia 6310.
It was a good phone, lasting days or weeks but it had no 3G, no wifi, no mail sync ... just like your phone now
What happens if you turn on the 3G and the Wifi ? DOes it drain the battery in couple of hours ?

Just by turning 3g off will help
looking at the graph you posted it looks like where it has poor signal is when you experience steep drainage.
good idea to have all the features turned off when you are not using it. especialy 3g cause it will keep draining to get a better signal.
try using one of those widgets to turn on and off 3g so you don't have to drill into settings every time you need it.

You only have to keep pressed the power button and select the second option to disablr 3g... Data network.
I will update soon!

Check Android OS and System use
What is the Android OS and Android System use?

i'm on debusrom, gingerbread 2.3, in spain.

your problem is probably only solved temporally, all method you said has already been proven not working. it's probably a serious driver issue in all exiting gingerbread roms for sgs, have a look at this: http://forum.xda-developers.com/showthread.php?t=1039696

My new broadcom wifi driver works like before update, phone is not sleeping ! It is not a wifi bug, it is not a dirty ROM flashing, it is not random app. Only 2 things left to consider Gingerbread core fault or broken device driver other than modem, wifi...

What battery status app is that you're using?

i am having batt drainage too...but is on MIUI rom...I am not sure why...my initial guess is kernel prob....still investigating it now~~~

So, why you post it in here if you are on MiUi ??

that means turning your SGS into a regular Nokia 1100. Why disable all features that make your device a smartphone?

i have used many stock and custom rom results are similar
disabling background data and syncronising gives better battery usage but makes it a simple phone

I'm shocked that turning off all that improved battery.

[Q] Android System using 72%...

Hi... I've had a LOT of battery issues after installing CM 7.0 RC3 or whatever that last one was. As the Nightly builds got higher - battery got worse. I have the latest radio for this Phone, and I've even replaced it. Battery life is horrible lately. I have two batteries (thought it was my battery) - I've cycled both of them a few times, and it still acts odd. I've wiped / reloaded, same thing. When I changed the radio from Euro to US, it seemed to be a bit better. But I'll be walking around my office with 99% battery, go out, smoke, talk to two people (20-30m) and it'll drop to 88% like it's nothing.
After changing the radio to US, the Cell Standby lowered, but Android System has crept up. I have TweetDeck set for 15m refresh, Google+ is set to push sync or w/e, I have two email accounts and I've disabled the FB/Twitter apps. I'm not overclocked at all either.
Anyone have any insight on this? I'm currently on Build 153. It seems like when I play Music it dies insanely fast. I used to get 12-24 hours on this, even playing music.
Screen shot coming.
Screenshot:
And I haven't done anything today. Sent a few texts, few G+ posts, and talked on the phone for like an hour... And I charged today from 0% to full (6 hours) when I was sleeping. No music, no games.

I have noticed weird activity from "android system" lately too. I run the latest build of MIUI... but I don't notice any crazy battery drain. I'm only down to 90% with it being unplugged for 5 hours, texting a bit, figured out a route with google maps, and some minor XDA browsing.

I agree. The latest miui build is great on battery life even with the optimized ui.
I text from morning until night, every 5 minutes or so a reply is sent. Also wifi is on and using the xda app every now and then.
I woke up at 9 EST and it is now 12 EST. I haven't reached 50% yet.
I have brightness turned all the way down, screen timeout to minimum, and kill apps once they are closed.
It's all about the rom and how you use it really.

You may want to install something like watchdog and have it monitor phone processes. I had something like this happen on stock froyo and it turned out to be the media scan process.
I cleared out my media dirs on the sdcard, and things went back to normal.

+1 on watchdog. I love that app. Its not a blatant task killer, it just gives you good information on your processes and alerts when one regularly comes above your set threshold.

guys, people have reported that updating google maps drains battery. try uninstall the updates, or temporarily remove google maps, then report another day of battery. even if gmaps isnt even showing there, its said to drain battery recently.

When phone is in Doze mode should i be seeing any wakelocks in the battery graph?

Hello i have posted this over on Reddit but thought that i may get more info on the problem on this site.
Sorry for the long post.
I am trying to find out what is causing my battery to drain 10-15% over night.
i have tried a factory reset 3 times and nothing has fixed it but 3 hours ago i done one again for the 4th time and so far it is still at 100% and i haven't hardly touched the phone so i am not sure if the reset has finally worked ( this time i did uninstall whatsapp too)
My question is, in this 3 hours of hardly touching the phone it is still at 100% but it is still showing being awake quite a few times in the battery graph and i was wondering if that means it hasn't entered doze because it still shows wakelocks? i hope this makes sense

People on reddit think it may be a wifi wakelock issue and have told me to try it on 4g to see if i still get any wakelocks which i will try for the next few hours.
Also after doing a factory reset does the phone need a few days or cycles to get the battery to working properly?
I should also note that for the past 3 or so days i have been trying different tests in the night when i am sleeping to see if it is an app causing the battery problem. I only have 3 3rd party apps on my phone which are reddit relay, whatsapp and tapatalk.
1. The first night when i noticed the drain and all 3 were on the phone it dropped about 10-15%.
2. The second night i only had the apps that came with the phone (they all updated first but no apps were opened like chrome so i dont know if they were set up and i was signed in) and it dropped 2%
3. the third night i removed tapatalk and kept relay and whatsapp and it dropped 10%
4. Today 3 hours ago i have removed whatsapp and the battery stayed at 100% for just over 3 hours until i picked it up and started using reddit and chrome so it seemed to not drain as fast but i still have all those wake locks.
Do you guys think it is the wifi wakelock problem or maybe an app? if it is the wifi problem will a new phone fix it as reboots and restarts with this phone doesn't seem to or if i get a new phone will it happen to that one and its actually a problem with my wifi?
Again sorry for the very long post, i am just looking to see if i can get to the bottom of this before my 15 days are up to get a refund from google.

Sorry to hear about the battery issues. Lots of complaints since the update from 6 to 6.01.
I think you have until January 22nd to return the phone, if you purchased it recently from the Google store.

Not sure if you are rooted or not, but if you are then I highly suggest downloading the Wakelock Detector app. If you are not rooted then I suggest rooting because it is the fastest way to get down to the root cause of the problem (pun intended). It will show you each process/app that wakes the phone from most to least.
Without downloading that you will just be playing a guessing game of uninstalling 1 app at a time, which could take forever. So save yourself the trouble and download Wakelock Detector. I think it is pretty safe to say most of the wake locks are from apps, so please do not return the phone because of that. I do not think a hardware issue could affect software wakelocks, and if it was a stock software bug, most or all people would be experiencing it. Good luck, feel free to report back to let us know what you found with it if you do root and download it.

Finow X3+ Battery Life help

I got my new Finow X3+ watch this past week and although I'm really impressed with the look, speed and overall capability of the device, all of that means squat when it can't make it past 8 or 9 hours on a good day with very limited use (basically only checking the time and notifications with only BT tether and cell on, no WIFI).
Not sure if it was bad OTAs that I installed when I got it or what's going on but I think it has something to do with phone not sleeping..If anyone can give tips to save battery that you've found for unrooted x3+ please let me know.
Also does anyone know of a way to disable the pedometer hardware as I'm pretty sure that's the a big issue. Thanks guys

The cell network is the batt hogger. What do you expect from that tiny batt? Because Watch standby is perfect.

It's true, since turning off cell service I can usually get almost a full day (7am-10pm) just using it as a companion watch with m2d but it's disappointing not being able to use it the way I thought I could.
But how are you getting 3.5 days on one charge? I don't think mine goes into full deep sleep possibly because pedometer always logging info? Please let me know if you know how to disable the pedometer constantly running since I'd rather use it and the Heart monitor on an "as needed" basis. Any help is appreciated.

You have installed this update?

Yea I did...should I not have installed it?

I read that drains the battery, you've seen any change?

I'm on latest. That 3d standby I got by turning off all sensor. Specially GPS. that hogs. Also pedometer. Use them when u need.

Yea I noticed bit more drain after that OTA but not overheating like some others. Gonna try factory reset like sonia said

I turned off GPS and WIFI and also ios notification which was big battery hog and it made big difference. How did you stop other sensors and pedometer though? I can't find those settings.

As ios turn off notifications?

Yea I turned off the ios push notification like you're showing in your pic, was taking about 10% battery in mine too. It didn't have any effect on notifications from phone to watch cause I don't use iPhone. Saved good amount in battery too.
So you know how I can disable pedometer if that's possible?

But as ios notifications is disabled?

I force closed ios notifications from the running apps list but for some reason it still takes some battery. Anyway I solved my issue: I did factory reset and then downloaded a phone booster app someone recommended on the Google group page.
Went from ~8-10 hours light use to about a day and half on one charge with moderate use. If anyone has battery life issues for seemingly no reason then try this. Thanks for your help mad.

What phone booster app?

Huge battery consumption, help needed

Hi all,
I am very satisfied with my device except for the battery life. I always had like 3-4 hours SOT. I was not happy but it was OK.
Lately I started charging the device every day after work (I would come home with dead phone after only 8-9 hours of it being unplugged).
So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

Are you rooted? On nougat? If so get background restrictor APK here on XDA and kill background apps and tasks so they can't run if you do not open them. Lower screen brightness. Install kernel auditor and shut off cores 4 and 8.

uninstall chrome. Then try accubattery (better bcause after android 7, they join all in android system to mask each app consumption. If after this you still can't find out where's the problem, start the phone in "safe mode". Even the consumption is better in this mode you must do a full wipe in recovery mode (vol up+power+home) and after this, reinstall one app each time and see after reinstall the second one and so on until you find out in which app is draining the battery
If you want you can starting by disabling background data in settings but I think isn't the clearer way to find out

This is going to surprise you.
I've had this phone for years and I've tried everything - and the BEST result is when you DON'T DO ANYTHING except disable Facebook and Instagram, and any Google Apps you don't use.
Do not tamper with anything else.
I figure that Samsung tunes this phone so tightly that if you leave it alone it operates as it should.
Anytime I disabled anything else, battery life suddenly and drastically reduced.
The phones runtime software kicks in and if you have disabled something it checks routinely, it will keep the phone awake constantly looking for a ping back from that process.
I just went through the whole process again meticulously, App by App.
Also DO NOT enhanced messaging OR the device antivirus. If you have, you must reset and then train yourself not to engage these too regardless of how hard The phone tries to persuade you!
Then - the battery life becomes like a normal phone which means you'll still need to charge everyday but it will take you through a full heavy day... And this is fantastic!
Honestly try it and you'll see what I mean. The S6 edge plus is so finely tuned, anything you block will start a feedback loop.

I had similiar problems , the way i fixed it, i disabled/uninstalled all samsung applications what i dont use, i disabled/uninstalled all google applications what i dont use. Cold weather (like -20C) will affect the battery life too.
Disable / uninstall apps you dont need. That helped me a lot and got even more battery life while at stock nougat rom with all updates installed.
try wiping cache from recovery and reboot your phone.
I hope this helps you
