What iOS shows after the swap
After the swap, Parts and Service History (Settings > General > About) lists the battery as “Unknown”, because iOS cannot verify an aftermarket battery. Battery Health still shows a percentage, 100% on a new battery, though Apple notes that health readings for a battery it cannot verify might not be accurate. The phone charges and runs normally. Apple explains both in its guides to Parts and Service History and genuine iPhone batteries.
About the iPhone 16 Plus replacement battery
This is a complete replacement battery for the iPhone 16 Plus: a new lithium-ion polymer cell with its own IC board and connector, with the adhesive already applied. It fits as a straight swap, with no soldering.
The iPhone 16 Plus was released in 2024. At 4674 mAh it sits between the iPhone 16 Pro (3582 mAh) and the iPhone 16 Pro Max (4685 mAh) in the iPhone 16 line-up. The iPhone 16 Plus can be opened through its removable back glass as well as from the screen, so the battery can be reached without taking the display off.

How to fit the iPhone 16 Plus replacement battery
For technicians and experienced repairers. Work on an ESD-safe bench, and never lever against a lithium battery: a punctured cell can catch fire.
- Prepare the bench. Precision screwdrivers, a heat mat or heat gun, a suction handle, plastic picks and fine tweezers, plus a 9 V battery or bench power supply.
- Open the phone from the back. Heat and lift the back glass, then unplug the battery connector before touching anything else.
- Release the old battery. Apple fitted it with electrically released adhesive: connect 9 V between the battery’s release tab and a ground point for about 90 seconds, then lift it out.
- Prepare the new battery. Peel the backing off the adhesive already applied to it.
- Fit the new battery. Line it up, press it into place, and reconnect it.
- Test and close. Check the phone boots and charges, then reseal it with fresh back glass adhesive.
If you would rather hand the job over, GA Tech NZ offers in-house iPhone 16 Plus battery replacement, and our repair tools range covers the bench kit.

Frequently asked questions
Is this a complete battery?
Yes. It is a complete battery with its own IC board and connector, so it fits as a straight swap with no soldering.
Will iOS show the battery as Unknown?
Yes. Parts and Service History lists it as “Unknown”, because iOS cannot verify an aftermarket battery. The phone charges and runs normally.
What will Battery Health show?
A percentage: 100% on a new battery. Apple notes that health readings for a battery it cannot verify might not be accurate.
How does the original battery come out?
Apple fitted the iPhone 16 Plus with electrically released battery adhesive. Connecting 9 V to the battery’s release tab for about 90 seconds lets the adhesive go, so the old battery lifts out without prying.
Do I need to solder?
No. It is a complete battery, so it swaps in without soldering.
Is the iPhone 16 Plus battery the same as the iPhone 16 battery?
No. The iPhone 16 Plus takes a 4674 mAh battery and the iPhone 16 a 3561 mAh battery, each shaped for its own phone, so the two are not interchangeable.
Is battery adhesive included?
Yes. The adhesive is already applied to the back of the battery: peel off the backing and fit it.
Which iPhone 16 Plus models does it fit?
Model numbers A3082, A3289, A3290 or A3291. Check yours in Settings, then General, then About.
Is this an Apple original battery?
No. It is an aftermarket battery, not an Apple part.
What warranty comes with it?
6 months against manufacturing defects. Physical damage, punctures and damage caused while fitting are not covered.
