Apple recommends that all users install and upgrade to iOS 14.5.1. Can older phones handle it?

Mobile phone manufacturers hope to let you experience the feeling of lagging through upgrades, because after experiencing it, you will be eager to change your phone. But to be honest, the cost of changing Apple phones is still quite high. Every time you buy a phone, you will feel psychologically entangled and painful, after all, it costs so much money!

Apple said iOS 14.5.1 includes bug fixes and provides important security updates, and it is recommended for all users to install. According to Apple's release notes, the update fixes a bug in App Tracking Transparency that may have prevented some users from receiving prompts from apps. "This update addresses an issue with App Tracking Transparency that previously prevented some users who had disabled 'Allow apps to request tracking settings' from receiving app prompts after re-enabling it." The security notes show that Apple has resolved memory corruption issues and integer overflow issues in WebKit, both of which could be exploited by maliciously crafted web content. Apple said there have been reports that these issues may have been exploited, and users are advised to upgrade immediately.

But is it really necessary to upgrade the system every time? I think it is not necessary, because sometimes when I see the description file of the system upgrade, it is mainly for the new machine to implement the upgrade, and it has nothing to do with old users, but it still reminds old users! These upgrades are unnecessary; but there are new versions, such as this time, which need to be upgraded to enhance security, but generally the new version is compatible with the old version. After being compatible with many functions, the file will inevitably become larger, the phone will become more stuck, and even some functions will be useless!

So I once mentioned a point, that is, for some old models, we should design some upgrades for these mobile phones, rather than treating them completely the same as new ones. This is also very critical! Of course, many companies are unwilling to spend the money to build system upgrades for old users, especially mobile phone manufacturers who rely on hardware profits to make profits. However, some mobile phone manufacturers can increase their profits from the software level. I think it is necessary to treat them differently according to different mobile phone manufacturers to gain a larger market.
