How do I know whether the iPhone SE 3rd Gen battery needs replacing?
Rapid drain, unexpected shutdowns, battery-percentage jumps or swelling can indicate a worn or faulty battery. We check the symptoms before fitting the replacement.

No. Battery replacement is a hardware repair and does not normally require a factory reset. Keeping a current backup is still sensible before any repair.
What battery option will be fitted?
The available option is shown on the product page. Where more than one option appears, compare the descriptions and choose the option that suits the repair.

This product is set up for same-day fitting. Book before travelling so we can confirm the repair slot and the current part availability.
Can I use the walk-in or mail-in service?
Yes. Book a walk-in visit near Liverpool Street Station or send the device through the UK mail-in service.
What warranty is included?
The completed battery replacement includes a 6-month warranty covering the fitted battery and workmanship, subject to the warranty terms.
