I've pre ordered a 16 pro (256gb - black). I need a new phone as my 13 pro is battered and the battery is dying but it doesn't feel like it's going to be a massive leap. I'm half considering cancelling my pre order and getting a 15 pro instead when a good deal comes up.
Why not get Apple to install a new battery for £85 and get at least 2 more years out of it?
