Hi, i was having a problem with my phone. It seems like bluetooth is hogging up my battery even tho im not using it.

Here's the screenshots:

Bluetooth was just turned on for abt 5 mins then i turned it off after using it then this happened. Is this just a bug or what? I noticed that my phone is draining faster.

Phone: Samsung Galaxy J5 SM-J500H
Android ver: 6.0.1 Marshmallow

Welcome to Android Central! Does that persist after a reset? If so, try wiping the cache partition -- follow the steps here, but instead of selecting Wipe Data, make sure you select Wipe Cache Partition: SAMSUNG J500F Galaxy J5 - How to Hard Reset my phone - HardReset.info

I already did that but problem still persists. Btw, this i flashed this phone with a marshmallow firmware from russia since there is no marshmallow update here in the philippines. Do you think this is the problem?

Yes, that's probably the issue. Flashing the firmware intended for a different variant of your model can cause various issues, and can also brick the phone. I would flash the original stock ROM again, and see if the problem goes away.

I use a stock phone with an automatic marshmallow update and I'm experiencing the same issue. When bluetooth is on it's the only battery user (100 %). When I use it only for a few minutes I can make the same screenshot.

Well, i flashed another marshmallow firmware from South Africa and it seems like the problem went away already. I dont like going back to Lollipop. Marshmallow looks so good
