Hii..

My nexus 5 battery is draining real fast like I'm only getting backup of 1 min per percent total of around 90 mins on full charge. I tried so many things to get this fixed but nothing worked, I tried to calibrate the battery, clearing the system cache ,app cache and on the top of these methods I installed a brand new battery but problem is still there same backup!! There is no information of this drainage in battery information page its just showing cell stand by which is 11%. Currently running marshmallow 6.0.1

Please help.

I didn't find the right solution from the Internet.
