Battery drain while sleeping

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.

deep sleep!
Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )

I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))

I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.

Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/

Lg G2 battery drain in Deep Sleep - No Wakelocks

This has been happening for a week now. My phone drains battery like 8-10% per hour. I have Wakelock detector and Better Battery Stats. They show almost no wakelocks. wakelocks are at 5%, the rest of the time it is sleeping. I'm on Cloudy G3 last version.
When using it non stop from 100% to like 5%, my phone lasts the same as before (3h - 3h30m, brightness at 80%), the problem is sleeping.
I tried Shutting Down, new kernel, unninstalling the apps I downloaded last 2 weeks, and now I flashed CyanogenMod 11 M12. This happens on CM too.
Any solutions? Is there something wrong with the battery, my phone?
Screenshots attached.
Thank you.

I am having the exact same problem for the past few months. I tried countless factory resets. Nothing helped. I'm suspecting either some sensors went bad and kept the phone awake or the internal memory went bad, because as soon as I started filling up my storage(after factory reset) my battery would go to hell. I don't think it's the battery capacity because, as you said, if I used my phone non-stop I could still get around 4h screen on time. It's something else that's misbehaving and preventing deep sleep but not on software side, since there are no wake locks.
I've now given up and yesterday took my phone to the service shop. Will see how it goes.

Galaxy S5 plus battery drain (G901F)

Hello everyone,
I received my S5 plus about 4 weeks ago, (After an overheating LG G3 and a unresponsive Oppo Find 7a i took this one) and all the time I have had a battery drain.
The first one was fixed with a factory reset.
After that the Android System and Android OS were draining battery. At one moment it became to mutch, so I did an reset again.
It was normal for a day an a half, after that the phone was awake/active all the time.
Now I still have the same thing, Android OS and System (Espescially System) are using a lot of battery.
here you have some samples
No photos because im still new
But Gsam says the Android System is using 40% and The android OS is using 20%
Al the other apps are using below 2%
Samsung battery says the System is using 10% and the OS 8%
I am running Android 5.0.2
Anything I can do? I disabled all of Samsung bloatware and other thing but it doesn't help.
I am not rooted and i dont want to. (Lose warranty)

its terrible - pure system without any apps installed and as i said 30% down over night - most uses Android System (or something like that) - i cant check now as im flashing back to KK again at this moment.
EDIT.. my pc died in the middle of flashing..... it is a bad day... download mode is still working, reflashing with kies.........
this problem started because of stupid KingRoot.. i downgraded to KK because i wanted to try if it works on KK...

after last night i lost only 3-4% so its ok, but i didnt use other apps than system so android and system are ~20% in battery stats.
i will test this KK for few more days but i feel it will be ok now.
as i said earlier, phone couldnt go in to deep sleep as much as it should, 300Mhz was used even when phone was idle - now it enters deep sleep for almost all idle time

Android OS Wakelock killing the battery!

Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.

If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT

Massive battery drain mi 9T

Hello guys! Yesterday I updated to miui 10.3.15 and i experienced massive battery drain overnight from android os. Last night I charged it full 100% and in the morning it was 19%. And this is with only 20 minutes of SOT. What may be the cause? Airplane mode is on, because I am on vacation in country where i cannot use roaming. I deleted the cache and rebooted the device and I think it is fixed but i will know when I fully charge the device.

try new beta android Q, is awesome for battery life
"9.9.26 - First MIUI 11"

Install Europe version ?

Im on mi-globe 9.9.26 and i suffer battery drain and heating issue

The pix for reference

This happened to me once. I believe is not a battery issue it's more like a process keeping wake up and eating the battery. When this happened to me I reboot the phone and charge it again and issue not happened again.

This keeps happening to me every few days.
I had to manually disable autostart for all apps. And i did not even know which ones I need and which ones I don't.
But it did not help, it keeps reapearing.

Same
This happened to me a few days ago and happens again every few days. I don't remember if it was after the installation of MIUI 11 or earlier, but I would think it is a software issue that Xiaomi should investigate.
The only solution I found was to close all applications and restart the phone before charging it.

I have no issues, my advice is whenever installing an os update it's always best to do a factory reset in order for the phone to run at optimal performance. When i updated i did not reset my device but i made sure to clear all app cache and reboot the phone after update. My SOT is normally 8-9 hours, also i made sure all my apps are up to date and their are no background apps that are draining my battery.
