Before you book
- If we discover water damage during your repair that affects the work, we will stop and let you know. A water damage diagnosis is applicable at the current fee, and we will confirm this with you before we proceed.
- If the screen or back is already lifting, the cell may be swollen, so book promptly and avoid charging it.
- If the phone has been opened before, we inspect the seals and connectors as part of the job.
- If the phone has had liquid exposure, a battery may not resolve everything and we check first.

Frequently Asked Questions
Is it worth replacing rather than upgrading?
If the phone is otherwise sound, a battery is a far cheaper way to get reliable all-day use again.
How much runtime will I get back?
A fresh cell restores close to original runtime. We fit quality batteries and test charging before returning the phone.
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.
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.
Is the battery replacement guaranteed?
Yes. The warranty for this repair is shown on the page and applies to the fitted battery.
Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
