About battery replacement

Batteries wear with age and charge cycles. We diagnose symptoms, check for swelling, and replace the battery when that is the right fix — without inventing fixed turnaround promises until we have seen the device.

FAQs

Is a swollen battery dangerous?

A swollen battery should be handled carefully. Bring the device in for assessment rather than pressing on a bulging back cover, and avoid using it if it feels unsafe.

Will you keep my data?

Battery replacement does not normally require wiping the phone, but you should still keep a recent backup before any hardware work.
