Replacing a battery on a 5S wasn't a problem — literally a trip downstairs and paying €20, if my memory serves me well. Done within 15 minutes. It would be neat

Replacing a battery on a 5S wasn't a problem — literally a trip downstairs and paying €20, if my memory serves me well. Done within 15 minutes. It would be neat if I could do it on my own, but that was good enough for me. And it means I'm on year 6 on this phone, and the lifetime is limited by software upgrades — and not just the OS, but also drivers and firmware.
