First of all i would say THE ANDROID PIE FOR NOKIA 8 IS OF NO GOOD.
There are no much improvements other than the cosmetic changes of pie ui.
Battery drain on standby is so huge. So huge that i lost around 20 PERCENT of battery while doing nothing. APPS ARE STILL RUNNING IN BACKGROUND EVEN THOUGH ADAPTIVE BATTERY IS TURNED ON. the older battery saver on oreo 8.1 WAS FAR BETTER.
People who deal with this software upgrades, do something ASAP. I lost an opportunity to do a presentation today because of this severe battery drain. SOMEBODY DO SOMETHING PLEASE.
