How to confirm your model
Check the model number in your device settings, or bring it in and we will confirm the exact Samsung Galaxy S25 before any work begins. If you are unsure which repair you need, our team will advise.
Before you book
- If the phone has been opened before, we inspect the seals and connectors as part of the job.
- If the screen or back is already lifting, the cell may be swollen, so book promptly and avoid charging it.
- If the phone has had liquid exposure, a battery may not resolve everything and we check first.

Frequently Asked Questions
How long does it take?
Often the same day where the cell is in stock. We confirm at booking.
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.
Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
Is the battery replacement guaranteed?
Yes. The warranty for this repair is shown on the page and applies to the fitted battery.
Do you recycle the old battery?
Yes, the old cell is disposed of responsibly.
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.
