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