Battery drain on S8

[khan69]

I checked my battery, it was 38% at 4:30am. I woke up at 12:30 and my phn is switched off. Why is my phn eating so much battery overnight? What is causing so much battery drain? I couldn't find Wats wrong from the screenshot of my usage also. 

Also I noticed after the march security patch update the battery is draining super fast.

Change your battery.Your battery health seems low.

Also check battery health with accubattery if below 70 then change it.

I've changed my battery 4 months back.
So will the service center people replace with a new battery free of cost or do I have to pay them ? bcoz it's not even 6 months since the battery was changed.
also Wats the price of S8 battery kit ?

Are you facing this issue everyday?If not then check the issue in safe mode>Put the phone in safe mode overnight and then check battery % drop when you wake up.

If you're facing this issue everyday then it might be problem with battery itself.

Also changed batteries have only 3 months of warranty so then won't change it.

yes almost everyday it's happening. dint check on safe mode though.

bro plz do this and check it
1.turn off mobile data or wifi when you are not using
2. force stop what's up app while you going to sleep
3. force stop all social media app while you going to sleep.
4.turn off location and sync setting too while u going to sleep.

plzz check your battery life after doing these thing and update me plz I want to know whether it works or not.

if it works use routines app which is available inside good lock app. it will really help to do all these things by one click.
