Original or manufacturer-grade part
The manufacturer's own cell. On an iPhone it keeps the battery health readout working without a service notice, which is the practical difference most people notice.

What this fixes
Why people book a battery replacement.
- Flat by the afternoonThe clearest sign. A battery is a consumable: it is rated for a few hundred full cycles and then it stops holding what it used to.
- Shuts down with charge still showingThe battery cannot deliver the current the device asks for under load, so it shuts down rather than corrupting anything. It often happens at 20 or 30 percent.
- Hot while charging, or hot doing nothingWorth looking at rather than living with. Heat is what ages a battery fastest, so a hot battery gets worse quicker.
- It dies at twenty percent and comes back when you plug it inA cell that can no longer hold voltage under load. It is the clearest single sign a battery is finished.
- It only lasts in warm roomsCold makes a worn cell fail sooner. A healthy battery does not care much about an Irish winter.
- Charging stops well short of a hundred percentSometimes battery health management doing its job, sometimes the cell. Worth checking which before replacing anything.
Before you spend anything
Is it definitely the battery?
A battery is the right answer most of the time, and it is worth ruling out the two things that imitate it.
IfIt drains fast and Battery Health still reads above 85 percent
Worth a diagnostic. A board fault or something staying awake in the background looks identical from the outside, and a battery would not fix either.
IfIt will not charge past a point, or charges only sometimes
That points at the charging port or the cable before the battery. We clean and test the port first, because very often that is the whole repair.
IfThe glass is lifting off the frame
Replace the battery, and do it soon. Fitting a new screen over a swelling battery just breaks the new screen.
IfBattery health reads above eighty percent and it still dies
Look at what is running before replacing the cell. A background process empties a healthy battery just as effectively as a worn one does.
IfCharging is slow as well as short
Check the port before the battery. A dirty port charges slowly and a worn cell empties quickly, and they are two different repairs.
If you are not sure which of these you have, that is what the free diagnostic is for. It costs nothing and it is the step that stops people paying for the wrong repair.
What parts do we fit?
Genuine Samsung service parts where they exist for the component, and premium aftermarket where they do not. You are told which one your repair uses before you agree to it, and the 360-day warranty is the same either way.
We will not describe a part as genuine, original or Samsung certified unless that is what is going into your phone. If the honest answer is premium aftermarket, that is what we say at the counter.
- A Galaxy battery comes out through the back, not the front. The rear glass is glued on and has to be heated off first, then replaced with fresh adhesive, which is why it takes longer than an iPhone battery.
- Samsung uses strong adhesive under the cell itself. Getting it out without deforming it is the part of the job that takes the care.
What the €50 includes
- A new battery, fitted and cycled
- The old cell removed and recycled properly
- Charging, current draw and health checked after fitting
- 360-day warranty on the part and the workmanship
Nothing extra gets done and charged for without you saying yes to it. Where the diagnostic turns up a second fault, the work stops there and you hear the price before it goes any further.
Dublin collection and return is available on weekdays if you cannot make it in. Nothing about the price or the cover changes because the courier brought it.
Choose the part
Two tiers, named before you agree.
On a battery the tier is not about how it looks. It is about whether the cell holds the capacity printed on it.
Value Edition
Premium aftermarket, tested to the same standard
A cell made to the original specification with cycle data behind it. We will fit this happily; what we will not fit is a cell nobody can tell us how it was stored or what it tested at.
€50The €50 on this page is our standard quote for this repair. Which tier suits your device is a conversation at the counter, and the price for each is on the table before you decide. The 360-day warranty is the same on both, because we would not offer a tier we did not think would last.
A cell sold as 3,300mAh that actually holds 2,900 shows full health on day one and falls off a cliff at eight months. That is the entire reason we are not the cheapest battery in Dublin.
How we do it
From the counter to back in your hand.
Tell us what it is doing
Two minutes online, or straight in the door at 4 Richmond Road. The more you can say about when it started, the faster we get to the cause.
Free diagnostic
We confirm what has actually failed before anything is ordered or opened. It costs nothing and it is the step that stops people paying for the wrong repair.
You approve the price
You hear the number first. If it is not worth it to you, that is a perfectly good answer and it costs you nothing.
The repair is carried out
Carried out here in Drumcondra rather than sent away, by people who do this repair daily.
Bench testing
We test what we replaced and everything that sits beside it, because that is where a rushed repair shows up.
Back in your hands
Pick it up from Richmond Road or have it couriered back across Dublin. Either way it carries the 360-day warranty.
Before it goes back
What we test every time.
A repair is not finished when the part is fitted. It is finished when the things around it have been checked.
Charge and discharge
Put on charge and watched draw current properly rather than just showing a percentage.
Heat
Felt and measured while charging. A battery that runs hot from day one is going back out.
Temperature during charge
A new cell that runs warm is a new cell we do not send out.
Health reporting after the swap
Confirmed in settings where the device reports it, so you can see the number for yourself before you leave.
Is anything on the device at risk?
Nothing about this repair requires reading what is on the device, and nobody here does.
Testing is a different matter. To prove a repair works we have to turn the device on and use it, which sometimes means asking for your passcode. Say no if you prefer and we will show you exactly which checks we cannot complete without it. Where you do give it, it is written on the paper docket and the docket is shredded. There is deliberately no field for a passcode in our system.
Take a backup before you come in. It is free, it takes two minutes on a device that still works, and it is the one thing nobody regrets having done.
Is it still water resistant afterwards?
Treat the device as no longer water resistant after any repair, including this one.
An IP rating is measured on a brand new, factory sealed device in a laboratory. It is a description of how that device left the factory, not a property it keeps. Heat, age and everyday knocks degrade the seal long before anybody opens it, which is why phones that have never been repaired still let water in.
Opening a device means cutting through adhesive. We refit with fresh adhesive, which gives you back a physical seal that keeps rain and splashes out. What we will not do is claim the original rating is restored, because there is no way for us or for any independent shop in Ireland to test that.
If the device lives near water, tell us when you book. It changes what we recommend and it is a two minute conversation rather than a surprise afterwards.
The 360-day warranty
Every completed repair is covered for 360 days on the part and the workmanship. If the display we fitted fails, or the fitting was at fault, we put it right at no charge.
What it does not cover is a new accident. A phone dropped again after the repair, fresh physical damage, liquid damage, or a fault in a part we did not touch, all sit outside it. That is the same limit any honest repair warranty has.
No fix, no fee. The diagnostic is free, and if the repair does not happen you pay nothing.
Three ways to get it to us
- Walk in to Drumcondra4 Richmond Road, Dublin 3. No appointment. Mon to Sat 10:00 to 18:00, closed Sunday. Most phone screens and batteries done in 15 to 45 minutes while you wait.
- We collect and returnDoor to door across Dublin, Monday to Friday, usually 2 to 4 working days. The repair takes the same time; the courier is the difference.
- Send it in yourselfPost it to the shop with a tracked, insured service and a note with your number. We cannot cover a parcel in transit, and that is the honest trade-off for the route existing.
Same repair price and the same 360-day warranty on all three. The only thing that changes is how the device travels.

€50, including the part, the fitting, the testing and the 360-day warranty. VAT is included. You get that figure confirmed before anything is opened, and if we cannot repair the phone you pay nothing.
15 to 45 minutes for most phones. If the diagnostic turns up something else, or a part has to be ordered, we tell you before you commit rather than after.
Treat it as urgent. A swelling cell is under pressure and pushing your screen off its frame. Stop charging it, stop pressing the screen back down, and bring it in. We dispose of swollen cells properly rather than putting them in a bin.
Most phone batteries are rated to hold about 80 percent of their original capacity after 400 to 500 full charge cycles, which for most people is two to three years. Heat shortens it, and so does leaving it on charge at high temperature.
Two to three years of normal use before it is noticeably worse. Apple and most Android makers rate a cell to hold around eighty percent of its capacity after several hundred full charge cycles, and Irish weather and fast charging both take their toll.
Yes, until it starts shutting down unexpectedly or the case stops sitting flat. Either of those is the point where it stops being a convenience question.
No. Checking is free and so is telling you it does not need replacing, which happens more often than people expect.

Recently purchased an iPhone 12 here, very impressed came with 100% battery health, very reasonable price and great service! Would recommend.
Excellent customer service bought my samsung A54 best price in dublin.
As I'm a lawyer, I need a reliable phone. For me, it's an office extension in my pocket. I decided to buy a Samsung S23 Ultra. I live in Drumcondra so being aware of their excellent reputation locally, I visited iMend last week. The manager and assistant could not have been more helpful. I bought the phone and it exceeds my expectations. On checking, the price was the lowest in Dublin. Anyone who needs a phone or a small electronic product will be well looked after by iMend. Great people to deal with!
