Frequently asked questions

What OnePlus 15 repairs are available?

The core repair options are screen replacement, battery replacement, USB-C charging port repair, rear camera repair, and back glass repair. Other faults such as speakers, microphones, buttons, wireless charging, and liquid-related symptoms can be assessed through our diagnosis service.

How do I know which OnePlus 15 repair I need?

Screen damage usually shows as cracked glass, OLED lines, flickering, or touch problems. Charging faults often involve the USB-C port, while fast drain or shutdowns point towards the battery, and a diagnosis is best if the symptoms overlap.

Can I walk in without an appointment?

Yes, walk-ins are welcome near Liverpool Street Station during opening hours. For a newer flagship such as the OnePlus 15, booking ahead is recommended so we can confirm the repair route and parts availability.

Do you offer a mail-in repair service for the OnePlus 15?

Yes, we offer a UK-wide mail-in service. Place your order online, send the device by tracked delivery, and we return it securely once the repair and testing are complete.

What warranty do OnePlus 15 repairs come with?

Most OnePlus 15 repairs include a 12-month warranty from the date of repair. Battery replacements include a 6-month warranty because battery performance naturally depends on charging habits, cycles, and usage.

Will my data be safe during the repair?

Yes, OnePlus 15 repairs are hardware-only procedures and do not require your data to be wiped. We still recommend backing up important files before any repair as a sensible precaution.
