Galaxy S7 Battery Drain Problem

[Nimal]

My Samsung Galaxy S7 battery is draining very fast. But the battery backup is good even if I make a continuous call for 1hr. But while I am using for Email, WhatsApp etc... The battery is draining too fast.

Pls advise a solution to solve this problem.

Try doing the battery calibration. Use the battery completely to 0%. Then full charge it while mobile switched off. Then again use it completely till 0%. Repeat 3 times.
