iPhone 16 Battery Installation

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

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.

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.

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.

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.

Once the new adhesive is aligned correctly and matches the old adhesive, press it firmly to the battery.

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

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

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

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

Hold the battery over its place in the iPhone, but don't lower it into place yet.

To ensure the battery is properly placed, use a spudger or your finger to connect the battery press connector.

With the battery connected, lower it into its place in the iPhone.

Use your fingers to press the battery into place.

Use a spudger or your finger to disconnect the battery to protect your iPhone during the rest of the reassembly process.
