About Battery Replacement Notifications
After replacing your iPhone 15 battery, you may see:
- "Important Battery Message": Indicates the battery’s history is unavailable.
- "Service" Status: May appear in the battery health section.
These notifications do not affect battery performance. They are part of Apple’s system for promoting their own repair services.
Note: Apple serialises parts, so even swapping batteries between two brand-new iPhone 15 devices will trigger these alerts.
To monitor your battery health accurately, we recommend tools like Coconut Battery.

Frequently Asked Questions
How do I know whether the iPhone 15 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.
Will a battery replacement erase my data?
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.
How long does the repair take?
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.
