Things to know before you book
- A new battery cannot fix a fault on the device’s main board. If symptoms continue after replacement, further diagnosis is the honest next step — we will tell you, not guess.
- Charging problems are not always battery problems — the port, the cable or software can be the cause. If it is not clearly the battery, we check before fitting anything.
- If the device has met liquid, the battery result can be affected by what the liquid reached — an assessment comes first.
The full story on our parts and testing: the parts we use, and why · the 12-month warranty.
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.
Repair knowledge
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.
Repair knowledge
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.

What happens if I wait?
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.
What this repair includes
Why choose ExpressTech for this repair
You get the price before any work begins. If we find something else, we stop and tell you rather than adding it to the bill.
The exact price is confirmed before any work begins. Complex faults, including liquid damage, no-power, intermittent faults and logic board issues, carry a €30 diagnostic fee. If you go ahead with the quoted repair, the €30 is credited in full toward the repair cost. If the device cannot be repaired, no repair charge applies beyond any agreed diagnostic or assessment fee.
4 hours
12-month warranty on parts and workmanship.
Genuine Manufacturer parts available for many repairs. We’ll clearly explain the available quality choices before work begins.
We do not access your personal data during standard hardware repairs.
Before your device comes back to you, we test the repaired function and the key functions around it.
Before you visit
- Keep a backup if you can — we recommend it as a general precaution before any repair. Your data is never accessed, transferred or erased during standard hardware repairs.
- Know your device passcode — before handover we test the repaired function and the key surrounding functions on the device itself.
- Walking in? We’re at 110 Baggot Street Lower, Dublin 2 — no appointment needed.
- Using Collection & Return? Book the previous business day, or before 10:00am, for priority same-day collection in eligible Dublin city areas; nationwide, collection and return typically takes 3–4 working days door to door.
12-month warranty
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.
If anything isn’t right after your repair, contact us with your ticket details — call 01 644 9555, WhatsApp, or email hello@expresstech.ie. Read the full warranty.
