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.

Battery drain all of a sudden. It's killing me!

Recently my phone has been dying really fast. I checked battery stats and Android system is what's killing it. I've tried everything to make it stop and nothing works. Does anyone else have this problem? Any idea on how to stop this? PLEASE HELP.

Boot into recovery then do clear cache partition. Should clear out whatever is causing this issue unless that app is still in there

Clearing cache could and probably will get rid of it. But I bought an app called Better Battery Stats, (id link it but im new) which tells you exactly what is waking up your phone while its off. Chances are you have a rouge app, that is just destroying your battery, as opposed to a system-wide problem. That app will tell you what it is.

Ignore the battery charging cycle. I'm just showing you what I have to go through also and somewhat fixed the problem.
I have and still have %50 android os usage. Before I did this mod, the android os was the highest usage and showed awake time as well. It was killing my battery from a full charge it drained down to zero in 12 hours with 1hr screen time and the phone never being in a deep sleep. It was aggravating because I wiped my phone so many times, tried different roms, took sim card out, no wifi, wiped cache, and wiped phone with nothing installed. Still the high android still persist and no deep sleep. I'm thinking it has to be Verizon doing something or Google that is waking up the phone.
Some how I fixed it or maybe the OTA fixed it. I odin mj7 and updated to the newest version and flashed beans. From the screen shot it shows my android os still high... but with no awake time. So my phone is actually in deep sleep mode now. It's weird but I semi - fixed it. I'm still clueless on why it's so high when previously screen time usually trumps as the number one usage spot. I still have no answer to this reason but I hope it helps a bit to fix this issue.

HEY same exact thing here. Android OS usage going nuts here. I personally think its related to certain wifi / router setups.
When im on 3g/4g all day, it doesnt happen. On the days that I am stuck at home on wifi, the android OS usage starts again.
Ive already Odin'd back to MI7, took ota to MJE, rerooted, installed beans b5 and its still happening.
I think its a bug with samsung / verizon wifi. Many times I will wake up my screen and see my GPS / Wifi being used for no apparent reason even with all location services turned off. I also notice my wifi indicators being on when i turn my screen on. Then after i turn my screen on and sit at my home screen for a few seconds. It all magically stops.
Mind you, this is with no apps installed other than what is in beans stock and nova launcher.
You guys should monitor while off wifi and see what happens. It was the first thing that struck me when i was on a road trip for 12 hours. My battery life was exceptional. If it is the wifi causing problems, i wonder what it is specifically.

Simply clearing the cache fixes this for me every time. I usually do it once every few weeks.
Settings..storage..tap on cached data and hit clear.

6P losing 50+ % overnight now... last three nights

I was losing no more than 1% per night until three nights ago. I have also tried wiping the cache partition (yesterday) to no avail. "Android OS" is listed as the top resource hog, and it looks like it is not letting the phone sleep.
It looks like "keep awake" under the Android OS entry in the battery is going for the entire time the phone is on.
Suggestions?

Something isn't letting your phone sleep/doze.
You need the check which applications are running.

WiFi scanning is on perhaps?

Exchange services? That was my issue. I had to give up on using gmail for my exchange account and download Microsoft outlook for android.

Thanks I will check those. Wifi scanning is likely on, but that has been on for months now... not sure why the sudden change. May have to just wipe the phone and see what happens. Google maps, when giving directions on my car Bluetooth, has also started cutting off the last 30% or so of the voice guidance every time. Maybe a wipe will fix that, too.

Impossible to tell what's causing the wakelocks with root. Best you can do is educated guess.

something was holding your device awake literally the entire time

Well I ended up doing a factory reset. All was good at least for the first night. I will update and troubleshoot more if needed.

Bluetooth on?

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

Has my battery degraded or its a software issue?

My battery lately has been draining really fast from doing minor tasks. 2-3 months ago I upgraded to the latest MIUI 11.0.4 and noticed a slight increase in drainage but nothing too concerning. For the past few days though, it has become really bad. An example is how today I charged my phone to 100 percent and within 8 hours it is now already down to 75 as I am writing this post.
What I did:
Charged it.
Left it idle for 4 hours
Browsed some Facebook feed for around 15 minutes
Watched YouTube videos for a total of 15-20 minutes
Left idle again for another 2 hours
Just now spent another 20 browsing some Reddit posts
I usually keep my mobile data as well as the WiFi connection turned off all the time and only turn them on when I need to use the phone. I don't have any IM apps running in the background all the time syncing messages except Kik and Snapchat for whom I've set a battery saving modes to close whenever not in use but again, like I said my internet connection is always switched off. I keep my screen brightness low all the time as well btw.
I usually charge it as soon as it goes down to 30-40%
Pretty sure tomorrow after a whole day of work having it sit idle and then doing some minor internet browsing its gonna drop to 30-40.
Here's a screenshot of my battery stats:

Not sure if this is normal as I remember it draining way slower than it does nowadays. I know that this phone is known for having a good battery life. Any suggestions on what I should do? Is there warranty for the battery in case it turns out to be faulty? I've been using this phone for a little over 6 months now.

I have terrible wakelock on 11.0.4.0.
Non rooted and I want to keep it like this.
Is it a common issue and should I go back to MIUI 10?

Hi, bro!
I had this wakelock in all versions (Android 8 or 9) I tried several times to find out which app does this, installing monitors made for it and so far nothing ... But yesterday I reset my RN7 and the wakelock didn't come back. I imagine it is an app that has not yet performed the initial configuration.

switch aosp(no gapps recommended)
i get 12 hours plus sot

Multiple apps. Of course I tried to fix it by deleting a couple of apps such as restricting the background activity in the most of the rest but I only succeeded to reduce the wakelock from 98% to 50%. The bad thing is, that if You do hard reset it's a temporary solution. Wakelock will return in maximum one month. So what is the solution? Returning to Miui 10 or AOSP rom if You want to run latest Android version?
