Overview
What this part is
Every phone battery wears out with charge cycles. On the iPhone XS that shows as a phone that drops from 30% to off, needs charging twice a day or slows down under load. A swollen battery can also push the screen away from the frame.
This 2659mAh cell is a direct swap for the iPhone XS battery. It comes as the bare battery with its connector. 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 iPhone XS off, remove the pentalobe screws and open the display from the bottom edge.
- Disconnect the battery connector before touching anything else.
- Pull the adhesive strips out slowly and lift the old battery without bending or puncturing it.
- Fit new adhesive, seat the new battery and plug in its connector.
- Reconnect the display, close the phone and refit the screws.
- 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 XS?
Yes, if Settings › General › About shows iPhone XS. It does not fit the iPhone X, iPhone XS Max or iPhone 11 Pro.
Does it fit the iPhone X?
No. The iPhone X uses an L-shaped two-cell battery. The XS battery is a different part.
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 XS, 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.
