I did the excersize - the answer is NOTHING!! The iPhone X is just not a good product.
Unfortunately I have the same issue. Went to bed 97% charged (set to airplane mode) and woke up at 35%!!!
The battery usage did not show anything different than during the day - this is really weird...
Yes ma'am!! Crazy- right? I feel ya!! My iPhone X is at 47% after I check emails for an hour in the am....
Just crazy - wish I didn't get the "upgrade" at all!!
Yes I have the same problem and just got my iPhone X today
Honestly - worst iPhone ever-- if you can return it, I would highly recommend. Apple doesn't seem to be acknowledging the problem. If my phone isn't good into a charger, it does within hours.
How do I reset my iPhone 10? I am pretty sure the problem with my battery life is from a previous backup of my old iPhone 6. Thank you!
iPhone x battery draining so fast.
