iPhone 16 Battery Installation

Step 1

Remove residual battery adhesive

⌕

• Use a pair of tweezers to peel up any large pieces of residual battery adhesive from the iPhone frame.

Step 2

Remove adhesive residue

⌕

• Use coffee filters or a lint‑free cloth and high‑concentration (>90%) isopropyl alcohol to wipe off any remaining battery adhesive residue from the iPhone frame.

Step 3

Remove the top battery‑side liner

⌕

• If your battery came with the adhesive installed, skip this step and the next four steps.
• Lay the old battery with the adhesive facing up next to the new battery. Lay the new adhesive on the new battery to see how it needs to be applied.
• Your adhesive may look slightly different or have different liners.
• If the battery‑side of your adhesive has two liners, remove the top liner.
• If the battery‑side of your adhesive has one liner, remove it.

Step 4

Apply the top of the adhesive

⌕

• With the old battery nearby so you can align the new adhesive correctly, use your finger to lightly press the new adhesive to the new battery.
• Compare the placement of the new adhesive with the old adhesive.
• If you need to adjust it, you can carefully peel the adhesive up and try again.
• Once the new adhesive is aligned correctly and matches the old adhesive, press it firmly to the battery.

Step 5

Remove the bottom battery‑side liner

⌕

• If the battery‑side of your adhesive still has a bottom liner on it, remove it now.

Step 6

Press the adhesive

⌕

• Lay the adhesive onto the battery and press it into place.

Step 7

Fold the conductive tab

⌕

• Use your finger to fold the conductive tab around to the front of the battery and press it into place.

Step 8

Remove the iPhone‑side liner

⌕

• Peel the iPhone‑side liner off of the battery adhesive.

Step 9

Connect the battery

Place the battery
