iPhone 8 running iOS 14.2 and terrible battery drain.
100% down to 85% within minutes of browsing whilst connected to my
home Wi-fi.
I would previously get near 2 days of usage out of a full charge but now I’m getting barely 10 hours.
Exact same issue since 14.2 on my partners gen 1 SE which I sent away to Apple who fitted a new battery 3 months back and had been working fine.
