with 7.1.2 update in the battery menu appeared a Background activity manager. How does it work? Is this a more sophisticated battery saver? If i enable it how does it affect app updates. It says that i wont receive them that often but it seems that i don't get them at all. for example i had lock screen cleaner on but whitelisted facebook messanger and i never got a notification.
also it surprises me that on nokia 5 manual anna posted, it says that you should charge your phone to 100% while battery science explains that we should be charging from 20% to 80% with occasional full drainage and full charge.
what should we do?
