What exactly does the warranty cover?
Every completed repair is backed by a 12-month warranty on parts and workmanship. It covers faulty parts and workmanship, but does not cover new accidental damage, misuse or unrelated faults after the repair. Liquid damage repairs are excluded from the 12-month warranty due to the risk of ongoing corrosion.
- Walk-in and prepay-online prices are identical; Collection & Return adds the flat €30 — there are no other charges.
- No additional paid work is carried out without customer approval. If we find another issue during repair, we explain it clearly and confirm the cost before proceeding.
- If your device can’t be fixed, there is no repair charge — only any agreed diagnostic or assessment fee for complex faults.
- You’ll receive updates by text and email throughout, and you can track your repair using your ticket details.
Your data
We do not access your personal data during standard hardware repairs. Your data is never accessed, transferred or erased unless you explicitly ask us to carry out a data-related service.
We recommend keeping a backup as a general precaution before any repair.
Symptoms: is this the right repair?
This repair may be right if you are seeing:
- Battery drains much faster than it used to
- Device shuts down unexpectedly
- Charge percentage jumps or sticks
If you are not sure which repair is right, our technicians will confirm the fault before any work begins.
Should I stop using it?
If the battery ever looks swollen, or the screen or back is lifting, stop using the device, unplug it, and tell us when you contact us.
What a successful repair restores
A successful battery replacement restores the capacity a worn battery has lost; charging and shutdown behaviour are tested before return.
Why did this happen?
Usually simple chemistry: every battery wears with charge cycles, and after a few years the capacity it can hold genuinely shrinks.
Sometimes heat accelerates it — regular fast charging in hot conditions, dashboards in summer, or a device that runs hot for other reasons.
Could a cheaper fix be enough?
If the battery lasts normally once charged but charging itself is unreliable, test a different cable and charger first — accessories cause a surprising share of “battery” complaints, and that fix is free.
If it only charges at an angle, or stops and starts, the charging port is often the real cause — a port inspection and clean is the cheaper first step before any battery is replaced.

A worn battery keeps losing capacity, and unexpected shutdowns tend to become more frequent. If a battery ever swells — the screen or back starts lifting — stop using the device, unplug it, and tell us when you contact us.

Everything for your Apple Watch Ultra 3
The right part for your repair
Where supply allows, we fit Genuine Apple parts. Otherwise we fit Premium OEM or Standard OEM parts, selected for performance, reliability and fit.
We use the right quality part for the device and repair. Where part choices are available, we explain the options clearly before work begins.
From the bench
Many high-quality replacement batteries use cells from major manufacturers such as Samsung SDI, ATL or Sunwoda. Where we offer a non-branded option, the part is selected for reliability, fit and performance — not because it is a cheap substitute.
