Hello all,
First of all, I am very surprised that there is whatsapp backhround activity whereas I have background app refresh turned off, for all apps.
Is there a way to turn it off? It drains the battery.
I am using latest iOS with iPhone 6s. Overall I have noticed big drop in battery usage after an upgrade from iOS 10 to 11. I also hate tye reason why I had to move to iOS 11. The Mail app did not sinchtonize with my Gmail account and Apple support asked me to upgrade to iOS 11. It fixed the problem, but now I have battery issues.
