S7 battery draining too fast.

S7 battery draining too fast. I have a Samsung S7 it's almost 2 years old. In the last month or two battery has been draining really fast. Overnight phone was fully charged to 100%, in max power saver mode, no use at all eas sleeping, in 6 hours phone is down to 70%. Is it time to replace phone? Or battery?

Sounds like the battery is in need of replacing. Either that or something is running in the background that is draining the battery, even when not being used.
