Occasionally the phone charges to 100% so that it’s able to accurately calculate the battery percentages.

Are you using a case?

Is the 13 Pro an option for you? You still get a high refresh rate screen and should be even cheaper.

13 pro has promotion 120hz adaptive screen, so that’d be my choice

I don’t regret upgrading from 13 pro to 15 pro, but mostly because I got the 15 pro 20% off and sold my 13 pro for a decent price. If I was paying retail then yeah think that I would regret.

Switch to LG G3

iPhone SE

iPhone XS

iPhone 13 Pro

iPhone 15 Pro

Favorite was probably the XS - loved the design, camera bump would be flush with cases, my first OLED screen, I kind of miss Force Touch - it was the first phone that felt really premium.

iPhone 13 Pro has a high refresh rate screen and can buy refurbished for ~ half the price of the 15 pro. That’d be what I’d look into
