Launch day 15 Pro. The battery feels ass but seeing the numbers here, I don’t think it’s me - the battery is just ass in general.

88% battery health, 479 cycles.

I got my iPhone 15 on Jan 19, 2024. Right now it says:
-Battery Health says Normal
-Maximum Capacity is 91%
-Cycle Count is at 367

I charge it daily through the USB-C port, mostly charging it when it's at 40-50%, but sometimes it reaches 20% depending on what happens that day.

I will say that the last 2-3 months, which would be some 14-15 months after I bought it, the battery seems to have gotten noticeably worse and drains faster, and I'm not using it any differently than usual.
 
Mine is still at 89% but yeah nothing what I expected to see on this big 15 PM 😬😬😬
But I bet it has to do with using betas frequently I guess - that’s why I won’t install iOS 26 betas !
