Frequently asked questions
Will I lose my data during a battery replacement?
No. A battery replacement does not affect your data, apps or settings. Your device is not reset as part of this repair.
How long will the repair take?
We order the part on receipt of your booking confirmation. Parts typically arrive the next working day, and the repair itself takes around 1 to 2 hours once we have the component. We will contact you to arrange your appointment once the part is in.
What warranty is included?
All battery replacements carry a 6-month warranty on the replacement part and the fitting. If the battery develops a fault within that period we will investigate and repair at no additional cost.
Could it be a charging port issue rather than the battery?
It is possible. If your diagnostics suggest a charging port fault rather than a battery fault, we will let you know before proceeding with any repair work. A diagnosis service is also available if you are unsure.
