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.
Frequently Asked Questions
How do I know my Oneplus 7T needs a new battery?
The usual signs are a battery that drains far faster than it used to, unexpected shutdowns even when there is charge left, and the device only running reliably while plugged in. You may also see sudden percentage drops, the device running warm, or slow charging. Your device's battery or device-care settings will often show declining capacity. If the back or screen is lifting, treat it as urgent, as that can mean the battery has swollen.
Check current turnaround and reserve a slot on our booking page.
How quickly can you replace the Oneplus 7T battery?
Most Oneplus 7T battery replacements are completed the same day when the part is in stock, often within a couple of hours of dropping in near Liverpool Street Station in London. We inspect the device first and confirm the timeframe before starting any work. Mail-in customers can post the device from anywhere in the UK and we turn it around as quickly as the post allows.
Not sure? It is worth booking a quick diagnosis first.
What quality of battery do you use for the Oneplus 7T?
We fit a quality replacement battery matched to the Oneplus 7T and test charging, power stability and capacity before return. Replacing the battery restores the runtime the device had when it was newer and resolves shutdowns caused by a worn cell. Every battery replacement carries a 6-month warranty.
See exactly how we work on our how we work page.
Will my data be wiped when the battery is replaced?
No. A Oneplus 7T battery replacement is a hardware-only repair, so your photos, apps and settings stay exactly as they are. We still recommend a recent backup beforehand as good practice, in case the device has damage beyond the battery. Nothing about the battery procedure touches your storage.
Have a question first? contact us.
Is a swollen or bulging battery dangerous?
A swollen battery is a safety issue and should be dealt with promptly. Stop charging the Oneplus 7T, avoid pressing on the bulge, and arrange a replacement as soon as you can. Swelling can lift the screen or back panel and, left too long, can damage nearby parts. Bring it in or post it to us and we will replace the battery and check the surrounding components.
Bring it in and we will check everything.
What warranty comes with the Oneplus 7T battery replacement?
Every Oneplus 7T battery replacement includes a 6-month warranty, which covers the replacement battery and our fitting. If a warranty-covered fault appears within that period, we put it right at no extra cost. The warranty does not cover fresh liquid exposure or new accidental damage, which we always explain before you book.
Our team is happy to help before you book.
