Samsung galaxy s5 battery Drainig fast My device is the Samsung Galaxy S5 SM-9000H. Its battery drains very fast, even when the screen is off. It drains 70% overnight. The battery level becomes only 10% in the next morning, although the phone would've done nothing overnight! 

Does anyone have a solution for this?
My Battery Draining Problem is also Solved by upgrading Android lollipop 5.0.1 to marshmallow 6.0.1.
