Aloah!
I bought the S7 Edge and used it in stock version. Then I noticed that the battery loses over 10% per night. So I decided to install the Superman ROM with root and deactivated some Samsung Features. But the phone still looses over 10% per night.
I have disabled WLAN, BT and GPS. The only activated feature is the always-on-display, but this could not be the problem, because of AMOLED. I know that Samsung bloates their phones with useless things and I only recognize this battery problem (mostly) on Samsung phones. So I think the battery loss must have to do something with the Samsung features.
So my questions are these two:
1. How can I find the battery-using processes?
2. Is there a near-stock-android ROM which is fully debloated? On the S5 the stock ROM had 1,5 GB and then I installed one which has only 400 MB. So there was much Samsung trash removed.

since you are rooted start by installing either Wakelock Detector or BetterBatteryStats app and see the output of those in the morning.
also is it a used or new phone? if its used then the battery might be faulty.
also try 1 night with AOD off and see if that gets rid of the issue.
Its a brand new phone. Ok, I try these two apps.
But what is AOD?

Always On Display :: AOD
Does this really take that much battery? I mean, its mostly black and that doenst consume battery (mostly).

Id bet thats where most of your drain is coming from. Im just going by what I recall, but believe AOD accounts for 1 to 2% per hour.
I like having the AOD at night so I keep it on regardless since Im pretty much able to charge my phone at work or in the car, its not a big deal.
Ok, I deactivated the AOD but still got around 7% loss.

Here is another
My phone has been in my pocket all day not being used until just now when I made this post
I should also mention it is fully stock
looks pretty standard for stock to me. 5 hours for 23% of the battery? That means about 20 hours a cycle? seems very standard for stock.
If you want more then you gotta go custom ROMS and Kernels.
If your rooted use SET CPU to make phone clock speed 322-400 mhz when the screen is turned of.
But why is it awake so much?
Search for "AndroidOS Bug" and you'll get the answer.

This bug really makes it hard to enjoy the note 3 as a whole. I was plagued by this pretty badly until recently I sort of found a workaround.
Some time ago I found out, that in offline mode the bug is not present. I came across it, when i was in our datacenter where the cell signal is a nightmare. I turned on offline mode and switched WiFi back on (thankfully we have a WiFi active there) and the battery drain was very low with active WiFi and bluetooth (headset connected) over a period of several hours.
I did still encounter the Android OS bug afterwards, but then once after my phone was fully charged, I put it into offline mode for some time (30 secs or one minute) and then switched back to normal and that day I had exceptional battery life (whole day = ~12h with some time checking, messaging and checking mail, with ~70% battery left) which i assume must be the actual battery life that the phone is capable of without bugs.
So long story short:
possible workaround for the Android OS bug: put phone in offline mode for ~1 minute, then back into normal mode
I would love to read if somebody tried this and gave some feedback.
Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.
Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day
I just found a pretty interesting bug that causes my G935FD phone to be constantly awake after a full charge, but will happily go into deep sleep after I restart the phone after the full charge. It reflects in the GSam Battery monitor as well as the battery life.
Maybe someone who has issue with the phone constantly awake (or very high Android System battery usage) can try this trick out. My software version is:
Baseband: APD1
Build: APDQ
My phone is rooted if it makes any difference.
Here are some examples:
After 10 mins charging and before reboot:

}
And after a quick reboot:
may b this is the cause
may be this is the cause of pathetic battery life on my phone. do u suggest a restart while still plugged in or after unplugging? Know any permanent fix for this?

I reboot them after unplugging.
I've just found this work around recently (as you can see my pathetic average doze time per charge).
Will try this for a few days to see if it helps.
Have you tried to wipe cache ? cause i've had the exact same problem over and over again and in my case it only happened with wireless charger. After I wiped cache partition it never happened again.
It is google backup bug. Turn off google backup and it should be gone.
Or restart your phone after each full charge.
Edit: it affects other phones too

Wow this is a colossal bug.
Yeah, it affects two of my phones, S6 and S7 edge!
Bought the phone from a friend who never had battery issues. He factory reset it, then gave it to me. I upgraded to 7.1.1 Dev preview last night via OTA.
Location is set to battery saving, no Bluetooth/NFC/etc. turned on. Google Now is Off.
Unplugged at 715am this morning, didnt turn the screen on again until 1045am.

If you are waiting for it to say was asleep I don't think they have that the fact it shows 24 hrs when at 89% shows its not using alot of battery I could be wrong but I have never seen anything stating it has slept

I'm pretty sure, not 100% though that it doesn't state this as it states "awake time" instead
and looking at your screenshots, although its not constantly awake there are breaks in the bars which would indicate it was "asleep"

Sure. Definitely some moments. But the screen was off for 3 hours. Isn't Doze or whatever supposed to kick in? 11% in 3 hours with literally no SOT.
Better question, what could be causing Android OS to keep the phone away for 50% of the time?
For Doze to kick in, your phone needs to be sitting still with the screen off, and not connected to a charger. That means no moving around and nudging the gyro or other motion sensors, no touching the screen or the buttons

You are leaving it and its not in your pocket or anything?

Yes, part of that time it was just on my desk at work.
How soon after all those conditions are met, does doze kick in?
Hello everyone,
My Discovery elite battery is draining pretty quickly. When it shuts down and I start charging it it starts charging from 0% but when I reset the phone while charging it jumps directly to 24 percent.
I changed my rom, cleared battery stats couple of times, used battery fix and calibrator apps and nothing worked.
Android system and the apps are saying that my battery's health is good, what do you think?
What should I do?

I thought it was just me. I also experience the same problem. It shuts down prematurely or drains fast. After being off for a few minutes and starts it my batt would show it at around 24% again.

Can confirm this is happening to me as well
Are you running a custom ROM? I'm on 4.4.2 AOSP posted by Muratt19
This actually happens in all roms that I used. Even the stock roms.

Have you considered buying a new battery? Thinking of buying a new battery but afraid of wasting 30€ if it's a phone issue

I'm buying a different phone. They practically do not have support in the Philippines anymore. No Service centers as well.
