Android app - Wake lock

[Grease]

Hello!

I wanted to give some (android) developer feedback since I recently discovered that even though I had spotify installed on my Samsung S6 Edge+ (SM-G926F), I have not opened or used spotify, and it uses ± 90mb of data per month, and 3hr and 30min CPU wake time per day while my phone screen is turned off, and wifi turned on.

I've noticed that this is displayed as "Android OS" in battery usage, but I used the WLK app to spot this behaviour- Spotify covered up 79% of the total wake lock time for my phone...

My intention is to just let the developers know- I'm an android developer as well - and I can imagine that these things are easily overlooked during development.

I hope this was useful. 
Kind regards!
