Why do Samsung S7 battery drains fast then usual when I walk with the phone

[AC Question]

I am using Samsung S7 for last one month. I have noticed

1. When I am sitting in my room, then the battery drains as usual.
2. But when I walk with the phone in my pocket the battery drains really really quick.

I saw the battery usage one of my friend who uses Samsung s6, it also situation as mine. Can anyone please give me a solution for this.

If you check the battery log, it will show you where the power is going... Be sure to put your screen to sleep before you pocket the device!
