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 Note 9 before any work begins. If you are unsure which repair you need, our team will advise.
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 phone has had liquid exposure, a battery may not resolve everything and we check first.
- If the screen or back is already lifting, the cell may be swollen, so book promptly and avoid charging it.
- If the device is completely dead, we run a quick diagnosis before confirming the battery.

Frequently Asked Questions
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.
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 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.
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.
Do you recycle the old battery?
Yes, the old cell is disposed of responsibly.
