I believe some Nexus 7 ROMs have been made with newer Android releases, but it is indeed pointless. It runs like shit even on the stock ROM anymore. Modern operating systems are built to take advantage of modern hardware; in my opinion, there is nothing immoral about software being less efficient. A lot of things can lead to less “efficient” software, including better security measures, graphical effects, support for more advanced software and hardware that simply requires greater complexity, ... I have trouble believing that software vendors are sabotaging their performance on purpose. I’d be more inclined to question the intent of silently throttling older phones to improve battery life, which is much closer to an identifiable way that older phone hardware gets slower. But there are so many demands being placed on phones. Lowering audio, input and graphical latency across the stack necessarily costs some throughput. Newer, more complex web browsers running bigger websites necessarily requires more CPU and RAM. These are self-evident truisms IMO. On the other hand, there’s just so many features that can drive new phones other than the obsolescence of old phones. Enthusiasts might want Wifi 6, Bluetooth 5.2, 5G—all features that can’t realistically be upgraded on existing hardware. Every day users might upgrade because their old phone has a cracked screen that costs more than the phone to fix, or perhaps their contract is up and the carrier or provider is offering essentially a free upgrade; because yeah, carriers certainly play into this role too, not only vendors of hardware and software. Some users might upgrade for features like eSIM, better battery life, wider coverage of international frequency bands, wireless charging... Something like postmarketOS is still good, but I really feel like these approaches will really start to shine in the coming few years. I believe it is the phones and tablets coming out today that are likely to remain relevant for a long period of time, personally. Absence evidence that, say, AOSP is being made intentionally slower, I have to sit on the side of doubt. |
