> Now as far as the iphone 6s being usable - that's my point. It is usable, on the old OS it was designed for.
That phone was running the latest OS when I gave it to my friend last year. I think it might have been running faster thanks to ios 13 (or whichever version improved performance). I believe you when you say your brother's iphone 5s became unusable with subsequent updates. But my 6s kept chugging along just fine, updates and all.
I'm delighted there's solutions for android phones like what you're talking about. This sort of thing is really important - I mean, they're fully fledged computers capable of way more than we're able to use today. Its crazy that people throw them out after a few years. My iphone 12 is faster than my 2016 macbook pro. And I still occasionally code on that laptop. If I could run OSX on my phone and use my laptop as a terminal for it, that would be really sweet. But I can't because Apple doesn't care, and I'm locked out of making changes like that on my own hardware. Using old phones as web / file servers would be fantastic.
Companies like Apple are actively incentivized by the market to make their old products feel worse over time. And for that reason I'm always impressed when occasionally they release an OS update that improves performance across the board.
I guess my take is, Android phones have an awful history of dropping official support for recent devices. I'm delighted the hacker community can and has stepped in to clean up android's mess. Its a shame they have to, but such is life.
I'm sad you can't do that on Apple devices, but one saving grace is that, the 5s aside, apple seems to do a much better job of official software longevity than android. I'm expecting my iphone 12 to last 5-10 years. I do wish the battery lasted all week though - that sounds phenomenal.
