I have been using pie on my nokia 5 from the past 3 days..As i have noticed yes the battery is draining little faster..I got to know its because the phone is trying to keep every app in memory and most of the apps are running in background (As it was an issue in oreo)..The phone on pie is performing extremely smooth..To get a better battery life..

Also heating issue in Nokia 5 after pie update for normal usage also.
