- If the device is completely dead, we run a quick diagnosis before confirming the battery.

Frequently Asked Questions
Is the battery replacement guaranteed?
Yes. The warranty for this repair is shown on the page and applies to the fitted battery.
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.
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.
Will I lose my data during a battery replacement?
No. It is a hardware-only procedure and your data stays exactly as it is.
How long does it take?
Often the same day where the cell is in stock. We confirm at booking.
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.
