Frequently Asked Questions
Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
Do you recycle the old battery?
Yes, the old cell is disposed of responsibly.
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.
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.
Will I lose my data during a battery replacement?
No. It is a hardware-only procedure and your data stays exactly as it is.
