Frequently Asked Questions
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.
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.
