Of course. Can’t think why that didn’t occur to me. I’ve not JB’d a phone in so long, I think the last one I did was the 5 or maybe the first SE. I think I lost interest when untethered breaks stopped and it became a little more complicated.

Hello. Can you tell me why this is?

I bought an “as new” refurbished iPhone 12 from Giffgaff at the end of June 2023.

Arrived in perfect condition with 99% battery health. Today, after less than five months conservative use, and only charging overnight, it is at 91%.

Is this a reasonable reduction in health in 4.5 months? Obviously not after reading these comments 👎
