My last phone was used for 6 years before the battery didn't last a day of light use. My new phone has a replaceable battery. I intend to use it for at least 10 years. Processors in phones haven't been changing much over the last few years. CPU throttling to deal with battery degradation is where most of the slowdown comes from.
