1. The battery may not be user replaceable, but it is replaceable. Apple will do it for you for like $80, which doesn't seem horrendous on a 3 year old $600 pho

1. The battery may not be user replaceable, but it is replaceable. Apple will do it for you for like $80, which doesn't seem horrendous on a 3 year old $600 phone. 2. Agreed, the battery page in Settings should say "your battery is old, performance will be reduced in demanding situations" 3. FWIW iPhone X has a noticeably longer battery life than iPhone 7 had. Some of that may be down to the OLED screen (which sounds like it may be a standard feature across all 2018 iPhones), but is likely also due to the battery getting more space in the chassis. I'd be going to bed with the 7 in single digit percentages, where last night my X had over 50% left.
