This has a different purpose. It’s if you want to connect your iPhone to a 2008 car that still has a 30pin port (that you adapted to lightning) or a 2013 base model that only has lightning for example. For specialty accessories basically

FYI you can get the back glass of a 12 repaired by a 3rd party for a reasonable price compared to a whole frame swap at the apple store basically.
Also the 13 board might still work if swapped into another totaled phone, just chuck it up on ebay. Someone will probably buy it as a project.

Hi there,
I’ve used an older Mac for quite a long time and have a clue what this might be.
Your computer most likely thinks either it’s overheating like crazy or thinks the battery can’t handle the power draw from the battery and tries to do anything it can to prevent a crash.

It has two strategies to do so: 1) Hardware wise it clock the CPU and GPU down as far as it can, depending on CPU model it might disable all but one core.
2) Software wise it will spawn those processes, back in the day I think it was thermald?, might have changed since powerd and configd sounds about right to do “nothing” in a loop with the highest priority. Therefore cooling the cpu down because it doesn’t have free time to do actual meaningful work.

You could verify this by running MacsFanControl or iStat Menus and check if a temp sensor or current sensor or voltage sensor goes crazy and reports weird values.

But as the computer actually crashes it’s probably the knockoff battery cant keep up with your computer and needs replacement again. I’d recommend an iFixit battery, or try contacting rossmann repair and see if they can offer a more compelling option.

Good luck!
