Let me preface this by saying I don't use this app. I use Chrome specifically, which is why it's surprising that I keep finding Google LLC active in the background. I left my phone off charge overnight and it's been active in the background for 6hrs 44mins despite being restricted and used 10.2% of the battery when it's supposedly "sleeping when not in use". It's used more than the OS itself. Quite frankly, that's not good enough when it shouldn't be doing anything at all.
