There’s nothing I do on my current phone that I couldn’t do on a phone ten years ago, technologically speaking. When I upgraded my phone recently, it was solely because of battery deterioration and because the previous model was out of service for security updates. I don’t think I’m alone here.
I literally bought an iFixIt kit to open my phone up (for a screen replace rather than a battery swap, but still) and could not get it open after an hour+ of trying. I’d definitely believe it’s because I’m inexperienced in modern phone repair, but I’m not a generally unsavvy person. I build computers and mess around with tech as a hobbyist. I had to take it to a shop and return the kit. It’s definitely not an easy process for some devices.
