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.
Apparently they use one of the faster IoT chips that’s supported for like 10 years.
There is no CPU that is ever going to be supported for 10 years for a consumer application. ARM CPUs today are 20x faster than they were 10 years ago, and the ARM/RISC-V chips a decade from now will likely be 10-20x faster than today.
Regardless, the Kryo 670 CPU in the Fairphone 5 is already 3.5 years old, and it’s not super special, it’s just a semi-custom Snapdragon SoC. Consider that 4G LTE launched 13 years ago in the USA, and in 10 years that Kryo chip in the FP5 will be older than that. Could you handle the performance of your last 3G phone today?
There is quite a large delta between 512 KVPS 3G and even rather slow 4G at say like 10 MBPS which allows you to stream 1080p video etc. Yes 10 MBPS is not super fast for downloading but it will get your tasks done within a decent time.
