Is This the Right Repair?

- Phone shutting down unexpectedly at 20–30% charge
- Battery percentage jumping around or not charging past a certain point
- Handset runs warm during charging
- Battery health below 80% (check under Settings > Battery)

How It Works
- Book or walk in – Book online or come to our workshop at 35 New Broad Street, EC2M 1NH.
- Replacement – The technician accesses the battery through the rear panel, replaces the HB486486ECW cell and reseals the chassis.
- Test and return – We confirm charging function, capacity and heat levels before returning the handset. Typical time: 1–2 hours.
Before You Book
- Charging fault first – If your P30 Pro is not charging at all, the issue may be the USB-C port rather than the battery. We will confirm this before any work begins.
- Liquid damage – Pre-existing water damage can affect battery performance independently of the cell. Let us know at the time of booking.

Frequently Asked Questions
How do I know my Huawei P30 Pro 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 Huawei P30 Pro battery?
Most Huawei P30 Pro 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 battery do you fit in the Huawei P30 Pro?
We fit a quality replacement battery matched to the Huawei P30 Pro 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.
Do I lose my data during a battery replacement?
No. A Huawei P30 Pro 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.

Is a swollen or bulging battery dangerous?
A swollen battery is a safety issue and should be dealt with promptly. Stop charging the Huawei P30 Pro, 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.
It is also worth checking your Huawei P30 Pro screen repair.
What warranty is included?
Every Huawei P30 Pro 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.
