Not really, charging speed can make a pretty noticeable difference to your battery life in a few years time.

I had an “eco-friendly” case before and it fell apart within a year, I now have a regular one and it looks almost brand new after nearly 2 years of use. If you ask me you will be causing more environmental damage by constantly buying new cases rather than getting one to last.

As someone who has a 13 mini, the upgrade is absolutely not worth it, the only big differences are the A16 chip which is basically just an optimised A15 and the Dynamic Island, which, at least for me, wouldn’t warrant an upgrade on their own. Honestly, the 13 series is really the best to be on at the moment, the chip is only one generation behind and the rest of the specs are pretty much identical to the newest ones.
