Overview
What this part is
This listing covers all four iPhone 14 models, and each option is a different battery. A worn battery shows as short battery life, the phone shutting down with charge left, or the case bulging where the cell has swollen.
Each battery is a direct swap for the model you select and arrives as the bare cell with its connector. The iPhone 14 and 14 Plus can be opened from the back glass, while the 14 Pro and 14 Pro Max open from the display. iOS may show a message that it cannot verify the battery, and Battery Health may not show a percentage. The battery still powers and charges the phone.

Professional installation
How a technician fits this part
- Power the phone off. Open the back glass on the iPhone 14 or 14 Plus, or the display on the 14 Pro or 14 Pro Max.
- Disconnect the battery connector before touching anything else.
- Pull the adhesive strips out slowly and lift the old battery without bending it.
- Fit new adhesive, seat the new battery and plug in its connector.
- Close the phone, refit the screws and check the seals sit flat.
- Charge to full and check the phone powers on and charges normally.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my iPhone 14?
Yes, as long as you choose the option that matches Settings › General › About. The iPhone 14, 14 Plus, 14 Pro and 14 Pro Max each have their own battery.
Does the iPhone 14 battery fit the iPhone 14 Pro?
No. Each of the four iPhone 14 models uses its own battery. Select the option that matches your phone exactly.
Will Battery Health show a message?
It may. iOS may show a message that it cannot verify the battery, and Battery Health may not show a percentage. The battery still powers and charges the phone. This happens with any battery not fitted by Apple.
Is it made by Apple?
No. It is a brand new, OEM-quality battery made to fit the iPhone 14 model you select, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. A damaged or bent Li-ion battery can catch fire, and the adhesive pull tabs snap easily.
How quickly will it arrive?
Orders placed before 4pm on a working day are dispatched the same day from Manchester by Royal Mail Tracked. Delivery is free on UK orders from £5.
