When a Pixel 8 Pro starts dying at 20 to 30 percent, it is usually a tired battery rather than a software fault. We can replace the battery and fully test the device.
Common report: it charges to around 80 percent quickly, then slows down a lot.
Newer features and faster connections can be demanding on the battery. If your Pixel 8 Pro has started dropping quicker than expected, a battery replacement can bring it back to dependable daily use.
Turnaround: Same day where possible, with testing included.
Warranty: 6 months for battery replacements.
Options: Walk in or use our UK mail-in service.

Frequently Asked Questions
What are the signs the Google Pixel 8 Pro battery needs replacing?
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 Google Pixel 8 Pro battery?
Most Google Pixel 8 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 Google Pixel 8 Pro?
We fit a quality replacement battery matched to the Google Pixel 8 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.

Will my data be wiped when the battery is replaced?
No. A Google Pixel 8 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 Google Pixel 8 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.
Any questions before booking? contact us.
What warranty is included?
Every Google Pixel 8 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.
