> You can in fact replace the battery with a non-Apple battery without issue.
No you can't. The apple batteries have a chip in them with a code that tells the phone they're authentic - only authentic apple components are allowed.
Its not a conspiracy theory. Apple is just a piece of shit company.
If you think being a piece of shit has to be a conspiracy, you're just naive.
Do you own an iPhone? Because I replaced my own battery with a non-OEM replacement and it works fine.
