S6 Edge - Battery drains fast

[Android Central Question]

Hello!
I have a Samsung Galaxy S6 Edge (SM-G925F). The problem is that the battery is draining very fast if I am using the phone. Firstly i thought it was the battery, but after a replacement with a genuine one the problem still persists. My battery drains in 3 hrs if I am using the phone only to stay on social media and type. I tried a factory reset, cache wipe, another firmware install, disabling apps, using the power save mode, but nothing helps!

Does someone know how to fix this?

What do your battery usage stats indicate as using the charge?

On a full charge it shows an usage of maximum 10 hours. On a normal usage it lasts about 4 hours.
