If your one-year manufacturer’s warranty has run out, it’s time to give that battery a fresh start! In this straightforward photo guide, we’ll walk you through each step of the process. Good luck with your repair adventure!
Step 1
Before diving into your repair, why not give our handy checklist a whirl to test the basic functions of your iPhone 12 mini? This little step will help you confirm if your repair adventure was a success!
– To turn off your iPhone, simply press and hold the side button and the volume down button together for a few seconds. It’s like giving it a little nap!
– After that, just swipe the slider from left to right, and watch as your phone gracefully powers down in just a few moments.

2 × 6.7 mm Pentalobe
Keep your screws and tiny parts organized during your repair journey! Grab an old sewing box or better yet, our nifty magnetic pad to make sure nothing goes missing. It’s like having a personal assistant for your screws—so you can focus on the fun part of fixing!
– Get your Pentalobe screwdriver ready and gently loosen those two Pentalobe screws. You’ve got this!
– Once they’re free, place them on your trusty magnetic pad. It’s like a cozy bed for your screws!
Step 3
Watch out for those hot fingers after heating! It’s best to warm up the display just enough so you can still give it a friendly tap.
The display edge is glued down pretty tightly, so let’s give it a little love with some heat first! Grab your trusty hot air tool, whether it’s a heat gun or a regular hair dryer, and warm it up nicely.
Step 4
To create a snug little space between the display’s edge and the case, grab a flat and stable tool. We think the iFlex is your best buddy for this job, thanks to its super sharp edges that slip in like a charm!
– Stick a suction cup on the lower edge of the display and give it a gentle pull upwards. While you’re at it, slide the iFlex tool between the display and the case like you’re sneaking in for a surprise!
– Now, grab a flat pick and slide it into a spot you’ve already loosened up. This way, the glue won’t have a chance to get all clingy again!
