I haven’t had an iOS device in ages, but Apple does seem to offer pretty decent support timespans for their phone hardware. Looks like it’s 6-7 years of support after the release date, which is respectable compared to the rest of the industry.

On the Android side, my phone stopped getting updates after 4 years, which feels too short to me. Not having access to Android 12+ wasn’t causing me any problems but I didn’t want to wait for some future bug, limitation or security flaw to emerge. I switched to LineageOS (just last night actually) to keep it going for another few years.
