Step-by-Step iPhone 16 Battery Replacement Guide
Duration: 45 minutes
Steps: 30 Steps
Ready to swap out the battery in your iPhone 16? You’ve got this! iPhone batteries are designed to maintain 80% of their power for about 500 charge cycles, which is roughly 18–24 months of use. If you find yourself charging your iPhone more frequently or it’s feeling a bit sluggish, it might be battery replacement time! The iPhone 16 and iPhone 16 Plus have a battery adhesive that likes to stick around, but don’t worry—just give it a little electrical love. Apple suggests using a 9V battery for 90 seconds, but if you have a power supply or a power bank with a 5–20V output, feel free to use that instead. Just remember, the time to loosen that adhesive can vary. In this guide, we’re using the VoltClip along with the FixHub Portable Power Station to tackle that adhesive. If you decide to go with another method, just follow along and adjust as needed with your power source. Once you finish the repair, you might see some messages about your new battery and lose access to battery health data, but don’t fret—your new battery will work like a charm! With iOS 18.1 and beyond, both genuine and aftermarket batteries will play nice with battery health features. Just run the Repair Assistant to reset those battery metrics and you’re all set!
Step 1
Let your phone’s battery dip below 25%—that way, we can keep everything safe and sound. A fully charged lithium-ion battery can be a bit of a drama queen when it comes to safety!
– First things first, let’s disconnect any cables from your phone. We don’t want anything getting in the way!
– Now, press and hold the power button along with either volume button until you see the option to power off. Slide to turn off your phone, and voilà, you’re one step closer!
Step 2
Ensure there’s a nice, flat spot near the bottom edge that’s spacious enough for a suction cup to grab hold.
– Got a nasty crack on your screen or back glass? No worries! Grab some packing tape and lay down a few overlapping strips over the glass. This will keep you safe and make it a breeze to take things apart. You’re doing great!

Step 3
– Grab your trusty P2 pentalobe driver and carefully unscrew the two 7.7 mm-long screws on either side of the charging port. You’re almost there!
Step 4
Be careful not to push your opening pick in too deep—your device might not appreciate it! To keep things safe, consider marking your pick to avoid any mishaps.
Feel free to add some personality by marking the other corners of your pick with different measurements. It’s like giving your tool a little flair!
Another fun option is to tape a coin to your pick about 3 mm from the tip. It’s a clever way to measure without the fuss!
– Grab your trusty opening pick and measure out 3 mm from the tip. Give it a little mark with a permanent marker so you know where to go—just a friendly reminder for your future self!
Step 5
Get ready to dive into the next four steps featuring the Anti-Clamp, our nifty little tool designed to make opening your device a breeze. If you’re not using the Anti-Clamp, feel free to jump down four steps for another method.
The Anti-Clamp works its magic by applying suction to both the screen and the back glass. To pop open just the back glass, make sure to secure the screen with some tape. For a detailed rundown on how to use that tape like a pro, check it out!
Want the full scoop on using the Anti-Clamp? Don’t miss our handy guide!
Just a friendly reminder: ensure the tape is only holding the screen in place and not the back glass.
– Snip off two strips of tape, then stick them along the long sides of your phone. Once that’s done, just fold them over the screen to keep everything snug and secure!
Step 6
If your iPhone’s surface feels like a slip-and-slide for the Anti-Clamp, just grab some tape and make it a bit stickier. You’ve got this!
– Gently pull the Anti-Clamp’s blue handle back to unlock those arms and get ready for action.
– With the back glass facing up, carefully slide the arms over the right edge of your phone, placing one suction cup on the back glass and the other on the screen. Aim to center those suction cups near the bottom edge for the best grip.
– Make sure your phone is supported and resting level while nestled between the Anti-Clamp’s arms—using a small box works like a charm.
– Give those cups a squeeze to create a solid suction bond. You’ve got this!
Step 7
If you’re out of tape, warming up the suction cups can help them cling better.
– Give that blue handle a little nudge forward to securely lock those arms in place.
– Now, give the handle a full spin—360 degrees, baby! Keep turning until the cups start to stretch out a bit.
– As the cups stretch, make sure they stay standing tall and aligned. If they start to wobble, no worries! Just remove the Anti-Clamp and slap some tape on there to help those cups stick.
Step 8
Just a friendly reminder: keep the heat in check! Overheating your phone can lead to battery drama. Let’s avoid that, shall we?
If you don’t see a gap forming after a minute, no worries! Just add a little more heat and give that handle a quarter twist. Sit back and let the Anti‑Clamp do its magic while you kick back.
– Grab your trusty hair dryer or heat gun and warm up the bottom edge of that back glass until it feels nice and toasty!
– Give it about a minute to let the adhesive loosen up and create a little space between the back glass and the frame.
– Slide an opening pick into that newly formed gap.
– Ease off the Anti-Clamp by using the pull tabs on those suction cups.
– You can skip the next two steps. You’ve got this!

As you carefully cut through the adhesive holding the back glass in place, remember to keep your pick no deeper than 3 mm. We want to avoid any accidental damage to those sensitive areas below!
– Be careful! There’s a fragile cable that connects the back glass to the phone, right beside the volume down button. Avoid inserting your pick here to keep that cable safe and sound.

Step 18
Alright, you’ve made it this far! The back glass should now be off the frame. If it still feels like it’s hanging on for dear life, take a moment to go around the edges with your trusty pick and see if there are any sneaky bits of adhesive or clips that need a little extra love.
– Gently swing that back glass to the right and watch it separate from the stubborn adhesive holding it down.
– Give that back glass some solid support with a clean, sturdy object – it’s like a little chair for your phone!
– Before you dive deeper, make sure to remove those opening picks. They’re done for now!

Step 20
– Gently slide the point of your trusty spudger into one of the cutouts on that middle connector cover.
– Give the cover a little nudge towards the left edge of the phone to free its hook from the logic board’s embrace.
– Now, go ahead and lift off the cover with a sense of accomplishment!
– When it’s time to put everything back together, just align that hook over its designated slot on the logic board. Press the cover down firmly and slide it to the right edge of the phone to secure that hook in place. Easy peasy!

Step 30
At this stage, your adhesive should be nice and loose! If your battery is still playing hard to get, just reconnect those alligator clips for another minute, then give it another go.
If you’re feeling a bit adventurous, grab a suction handle to gently coax the battery out. If it’s still being stubborn, don’t stress—just go back and repeat the previous step.
