Frequently Asked Questions
What should I do if the battery looks swollen?
Stop charging it and book promptly. A swollen cell can push on the screen or frame.

Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
How do I know the battery is the problem?
Fast drain, early shutdowns, only running on the charger or a swelling cell are the usual signs. We confirm before any work.
Will I lose my data during a battery replacement?
No. It is a hardware-only procedure and your data stays exactly as it is.
Is the battery replacement guaranteed?
Yes. The warranty for this repair is shown on the page and applies to the fitted battery.
