iPhone 15 Logic Board Replacement
Duration: 45 minutes
Steps: 59 Steps
To keep everything running smooth, make sure to swap out the matching parts along with your new logic board.
Ready to tackle the logic board swap in your iPhone 15? Grab some replacement back glass and screen adhesive to get the job done right. If your battery is looking a bit puffy, make sure to handle it with care and think about replacing it too. Remember, due to Apple's parts pairing quirks, the magic of your iPhone's features hinges on the logic board. Even a genuine replacement board might not do the trick without Apple's special calibration. To keep everything running smoothly, don’t forget to swap out these paired parts along with your new logic board: the Screen (for that True Tone and Auto-Brightness goodness), the Front Camera and Sensors (for most of the fun features), and the Battery (to keep that battery health data intact). If you need help, you can always schedule a repair.
Step 1
Let that battery of yours run down to below 25%! A fully charged lithium-ion battery can be a bit of a wild card when it comes to safety. So, let's keep things chill and make sure it's not too charged up before diving in.
- First things first, let’s give your phone a little breather. Unplug any cables that are connected to it.
- Now, let’s get that phone to take a quick nap! Press and hold both the power button and either volume button, then slide to power it off. Easy peasy!
Step 2
Find a nice, flat spot near the bottom edge—big enough for your suction cup to get a good grip.
- If your screen or back glass is seriously cracked, slap some overlapping strips of packing tape over the glass to keep yourself safe and make taking it apart a breeze.
Step 3
If you push the opening pick in too deep, it could mess up your device. Mark your pick at the right spot to keep things safe and sound.
Feel free to mark the other corners of the pick with different measurements to keep track.
Or, for a quick hack, stick a coin on your pick about 3 mm from the tip to act as a handy depth guide.
- Grab your trusty permanent marker and measure out 3 mm from the tip of that opening pick. Give it a little mark – you'll thank yourself later!
Step 4
- Grab your P2 pentalobe screwdriver and take out the two 7.7 mm screws hanging out by the charging port. Easy does it—let’s keep those screws safe for later!
Step 5
Heads up! Don’t crank up the heat too much—the battery really doesn’t like getting too hot and could get damaged.
- Grab your hair dryer or heat gun and warm up the bottom edge of the screen until it feels nice and toasty to the touch.

Step 7
Heads up! When you’re slicing through the adhesive holding the screen, watch out for these tricky spots to keep things smooth and safe:
- Two fragile cables connect the screen to the phone—one sits just above the mute switch, and the other hangs out roughly halfway between the volume down button and the phone's bottom edge.
- Around the phone’s perimeter, there are several spring contacts. Be super careful not to shove your pick too deep near these spots to keep those contacts from bending out of shape.
Step 8
Keep your opening pick no deeper than 3 mm along the bottom edge, or you might find yourself in a pickle!
- Gently slide your pick back and forth along the bottom edge to loosen up that stubborn adhesive.
- Keep your pick wedged in the bottom right corner so the adhesive doesn’t sneak back together.
Step 9
- Warm up the right side of the screen until it feels comfortably heated to the touch.
Step 10
Be careful not to push your pick in more than 5mm along the right edge.
- Glide your pick around the bottom right corner and head toward the power button. You'll bump into a clip holding things tight—no worries, that's just part of the adventure.
- Flip your pick so the flat side slips right under the screen, like you're sliding into home base.
Step 11
- Grip the pick with one hand and gently twist it to pry open a little space between the screen and frame, releasing the right clip.
- Slide a second opening pick in just to the right of the first one.
Step 12
- Gently slide the first pick down to the bottom right corner of the screen.
- Next, slide the second pick up to the top right corner to loosen the adhesive.

Step 13
- Warm up the top edge of the screen until it feels pleasantly toasty.
Step 14
Keep your pick shallow—no deeper than 3 mm along the top edge to avoid any surprises!
- Pop a third opening pick into the top right corner, just above the last one you placed. You've got this!
- Gently slide your pick around that top right corner and along the top edge until you hit the top left screen clip. You're making progress!
Step 15
- Give your pick a little twist to slide its flat edge right under the screen.
- Now, give your pick another twist to pop that top left screen clip loose.
- Gently slide your pick over to the top left corner and keep going!
Step 16
- Warm up the left edge of your screen until it feels nicely toasty—just enough to help things loosen up.
Step 17
Keep your pick no deeper than 3 mm along the left edge to dodge those sneaky cables connecting the screen to the phone.
- Gently slide your pick around the top left corner of the screen and along the left edge to pop those clips loose and free the adhesive holding it down. You've got this!
