Frequently Asked Questions
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 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 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.
Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
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.
