There is no update needed a factory reset fixed the issue and the battery is now amazing. I got 1day and 1 hour off charge with 6 hours screen on time and 20% left
Sounds like total BS to me. I've been using my phone since 6am this morning and it's about 7 and I'm down to 92% from 100%. My iPhone x is still at 100% so I have no idea what's going on here.
Background apps?? WQHD resolution the culprit?? Help us out Sammy!
