Frequently Asked Questions
What are the signs the iPad Pro 12.9 3rd Gen (2018) 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. You can check this under Settings, then Battery, then Battery Health and Charging. 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 long does a iPad Pro 12.9 3rd Gen (2018) battery replacement take?
Most iPad Pro 12.9 3rd Gen (2018) 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 iPad Pro 12.9 3rd Gen (2018)?
We fit a quality replacement battery matched to the iPad Pro 12.9 3rd Gen (2018) and test charging, power stability and capacity before return.

Will my data be wiped when the battery is replaced?
No. A iPad Pro 12.9 3rd Gen (2018) 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.
My battery looks swollen, what should I do?
A swollen battery is a safety issue and should be dealt with promptly. Stop charging the iPad Pro 12.9 3rd Gen (2018), 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 iPad Pro 12.9 3rd Gen (2018) screen repair.
What warranty comes with the iPad Pro 12.9 3rd Gen (2018) battery replacement?
Every iPad Pro 12.9 3rd Gen (2018) 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.
