Bought a new Nokia 1 Device with Go edition(Android 8.1.0 with 5 August 2018 Security patch).
Installed Avast Mobile Security and activated it.
It runs in the background for some time and then gets killed at some random time.
Visited Avast forum(https://forum.avast.com/?topic=222075.msg1480587) and disabled "Battery Optimization" and granted "Accessibility Permission".
Still the behavior is same.
The device has 1 GB of Ram and 8GB of ROM.
Also the mail(Protonmail) syncs only when I open the mail app, same is the issue with the Telegram messenger, everything was working as intended on my previous device, without any glitch.
I appreciate the suggestion - but my battery seems to be behaving quite admirably. Below is a screenshot of the battery stats since it was last on the charger this morning - as you can see, the biggest user of the battery is Android System - nothing else even comes close. The screen used a paltry 1% compared to Android System's 32%. I still have 64% battery remaining - so it doesn't seem to have anything to do with battery. No "hidden" apps are showing up as running and using a lot of battery either. Not saying I'm right - not saying it DOESN'T have anything to do with battery, just I don't see any evidence of it from these stats. WhatsApp Status
Other suggestions ...?
