cheese_greaterHow fuckup-proof is replacing your own iPhone battery?
Apple and ifixit have complete guides for take apart and replacement on their websites.
My recommendation is to buy a real Apple battery if you’re going to do this. Lithium ion batteries from shady sources are a good way to ruin your phone or worse, start a fire.
Apple actually offers a flat rate battery replacement for recent iPhones and in my opinion it is worth the money.
