Frequently Asked Questions
Do you recycle the old battery?
Yes, the old cell is disposed of responsibly.
Is the battery replacement guaranteed?
Yes. The warranty for this repair is shown on the page and applies to the fitted battery.
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 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.
Will I lose my data during a battery replacement?
No. It is a hardware-only procedure and your data stays exactly as it is.
