Your battery repair
Premium
Selected for reliability, fit and performance. Fitted and tested by ExpressTech, with a 12-month warranty on parts and workmanship.
Genuine Apple
A Genuine Apple battery, fitted and tested by ExpressTech, with a 12-month warranty on parts and workmanship.
Premium and Genuine Apple battery repairs receive the same care, testing and 12-month warranty on parts and workmanship. We explain the part options for your iPhone before you choose.
Depending on your iPhone model and battery option, iOS parts messages and battery-health reporting can differ. We explain what applies to your phone before the repair.
One thing we check rather than assume: exactly what iOS shows for Battery Health and service messages after a replacement is something we verify model by model. Ask us about your model before you book — we’ll tell you straight.
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 draining quickly through the day
- Unexpected shutdowns even with charge remaining
- Battery health warning shown by the operating system
- Slow charging or device not holding charge
- Device only works while plugged into power
- Swollen battery, raised screen or back glass movement
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
Battery replacement addresses a worn or faulty battery. Unreliable charging alone does not confirm a battery fault; we assess the cause before recommending repair. Charging and shutdown behaviour are tested before return.
Fast repairs, handled properly
Many iPhone 17 Pro Max battery replacements can be completed in around 60 minutes. If a part is not in stock, common iPhone batteries can usually be sourced within 24 hours, and some specialist parts may take a few working days. We confirm timing with you before any work begins. Fast turnaround, without cutting corners.
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 battery life is normal once charged but charging is unreliable, check the cable and charger before booking a battery replacement. Charging trouble alone does not establish that the battery needs replacing.
If charging only works at an angle or keeps stopping, we check the charging connection before recommending a battery replacement. Port cleaning is €30 where debris is the cause, credited toward port replacement if needed.

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.

Will replacing the battery affect my data?
No. A battery replacement is a hardware-only repair. Our technicians do not view personal files, photos or messages as part of the work. We still recommend a backup before any repair as a general precaution. If a repair ever needs data access, we discuss it with you and confirm consent before any work begins.
What battery options are available?

Will my iPhone show a battery message after replacement?
Depending on your iPhone model and battery option, iOS parts messages and battery-health reporting can differ. We explain what applies to your phone before the repair.
Is iPhone 17 Pro Max battery replacement worth it?
A battery replacement may be worthwhile if the rest of your iPhone is working well. We consider its condition and the repair quote with you. A new battery does not fix unrelated faults or guarantee a particular runtime or lifespan. If the cause is unclear, we check it before any work begins.
Is a premium battery a good choice for my iPhone?
Our premium battery option uses a high-quality replacement selected for reliability, fit and performance. Before returning your iPhone, we test charging, battery reporting, shutdown behaviour, fit, heat behaviour and performance. The repair carries a 12-month warranty on parts and workmanship.
