Frequently Asked Questions
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 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.
Can I walk in or post it?
Both. Walk in near Liverpool Street Station or post it with tracked return.
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.
Do you recycle the old battery?
Yes, the old cell is disposed of responsibly.
