So I took my iPhone X into the local Apple store and asked them if it would be possible to change out my battery - according to my settings, I’m only getting 89% charge. Which is surprising to me, considering the phone is only 15 months old (or maybe this is normal?). They strongly suggested that i NOT have it changed out (yet) ... and wait until it gets down down to 79~80%. Didn’t sound like they WOULDN’T do it, but they cautioned me not to just because of the risks involved, opening up the device. Any opinions on this? I’m gonna have this particular phone for a while, and it would be nice to put a fresh battery in it, but not if I’m risking damaging the phone.
