Is it "normal" that the battery does not last 8 hours? Set to QHD+ and 120Hz and absolutely normal use...occasionally whatsapp, internet, email, apps.... thats it! I don't game on this thing! Reset...reboot...uninstall apps... Optimise apps... this and that... tried everything... no success! So is this common or do I need to go complain? My Xiaomi Redmi Note 7 Pro lasts with 4000mAh battery easily 2 days! Sure only FHD display and and 6.3 inches...aaaber...8 maximum 10 hours!?!?! Do I have to accept this? Thanks in advance! Greetings
