So recently I’ve been seeing the trend where Android OEMs such as Google, Samsung, etc. have been extending their software release times up to like five, six, and seven years after device release. Clearly, phone hardware has gotten to the point where it can support software for that long, and computers have been in that stage for a very long time. From what I can tell, the only OEM that does this currently might be Fairphone.
Edit: The battery is the thing that goes the fastest so manufacturers could just offer new batteries and that would solve a lot of the problem.
On a general note I would say for the individual consumer it doesn’t matter so much if they keep releasing yearly, we just don’t have to buy yearly.
It’s kind of a waste of resources for the manufacturers supporting more models than necessary. If that leads to shorter support schedules that’s when it impacts us. But as you observed they seem to be lengthening at the moment.
I’m currently on a Pixel 6 from 2021, that I bought used from someone who was chasing the latest and greatest. I have no reason for changing yet. After October 2026 when support ends I’ll see if I have to migrate to Graphene OS or something. If no secure path forward exists I may have to get newer hardware then.
