iPhone 16 Pro Max Battery Replacement
Duration: 45 minutes
Steps: 81 Steps
Here’s how to swap out the battery in your iPhone 16 Pro Max. iPhone batteries usually keep about 80% of their capacity for up to 500 charge cycles, which is around 18–24 months. If you find yourself charging more often or your phone feels slower, it might be time for a new battery. If the battery looks swollen, be extra careful while handling it. You’ll need a replacement battery and back glass adhesive to get this job done. Starting with iOS 18.1, battery health works with both original and aftermarket batteries. After you finish, run the Repair Assistant to reset the battery stats.
Step 1
Let your iPhone's battery dip below 25%—a low charge helps keep things safe when handling lithium-ion batteries. If you need a hand, just schedule a repair.
- Disconnect any cables from your iPhone—give it some solo time.
- Press and hold the power button plus either volume button, then swipe to turn off your iPhone. Nap time for your device!
Step 2
Make sure smooth area near bottom edge is big enough for suction cup to stick to
- If your screen or back glass is badly cracked, lay strips of packing tape over the glass to shield yourself and make disassembly smoother. This little trick keeps glass shards in check and helps you work more safely. When you're ready to move forward, and need a hand, you can always schedule a repair.

Step 3
- Grab your P2 pentalobe screwdriver and gently unscrew the pair of 7.4 mm screws on each side of the charge port. Keep them safe—you'll need them later. If you hit a snag or want a pro to take care of it, you can always schedule a repair.
Step 4
Hey there! Just a friendly reminder: if you push that opening pick in too deep, it might just give your device a little ouch. So let's mark that pick to keep things safe and sound.
Feeling crafty? You can also mark the other corners of your pick with varying measurements for extra precision.
For a fun twist, try taping a coin to your pick about 3 mm from the tip. It’s like a mini measuring tool!
- Grab your trusty opening pick and measure 3 mm from the tip. Give it a little mark with a permanent marker, just to keep things clear and precise. You've got this!

Check out the camera cutout and those little notches along the top and bottom edges to get a clear idea of how the adhesive will fit snugly into the frame.
- Place the adhesive sheet onto the frame to check it’s facing the right way before sticking it down.
Step 63
Be careful with that sticky glue! It loves to stick to everything, so hold off on letting it get cozy with anything until you're ready to give it a proper home on the frame.
If your adhesive has a bunch of liners, go ahead and peel off the one that reveals the sticky side meant for the frame.
- Find the little tab on the corner of the adhesive sheet and peel back just enough liner to reveal about a third of the sticky side.
Step 64
Once you press the adhesive into position, it's a one-way street—you won't be able to shift it around. If you need to adjust, you'll have to peel it off and start fresh with new adhesive. Need a hand? You can always schedule a repair.
- Gently line up the sticky edge of the adhesive strip with the matching edge of your iPhone's frame, making sure it’s just right.
- Once everything is looking good and aligned, softly press that adhesive strip onto the frame like you're giving it a little hug.
Step 65
No spare adhesive strips? No worries! You can put your iPhone back together and use it as usual, but just remember your water resistance will be taking a little break until you swap in new adhesive.
When the adhesive is lined up just right, the edges will snap perfectly into place—like a glove.
If the adhesive is a bit off, gently tug the long edges to get it sitting pretty with the frame.
If the adhesive starts to crease or wrinkle, don’t panic—peel it off and try again with fresh strips for a smooth finish.
- Keep peeling back the liner from the adhesive, gently pressing the sticky part into place as you go. Take your time and enjoy the process—you're almost there! If you need a hand, you can always schedule a repair.
Step 66
Those tiny grounding clips are delicate—try not to bend them! If one gets out of line, just nudge it back gently with your fingers or tweezers.
Be gentle! Pressing too hard might stretch and mess up the adhesive.
- Grab a spudger and gently nudge around the entire edge of your iPhone to loosen that stubborn adhesive. Keep it friendly, keep it steady—you're on your way to a smooth repair. If you need a hand, you can always schedule a repair.
Step 67
You might notice some liner hanging out around the edges—don’t peel those off just yet! They’re keeping your adhesive from sticking to random stuff during reassembly, so let them chill for now.
- Grab a spudger or use your fingers to lift the pull tab attached to the big front liner. It’s usually tucked in a corner of the liner, waiting for you.
- Once you’ve got the pull tab, give it a gentle tug to peel back the large front liner from its adhesive grip. Easy does it!
