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.

The Galaxy S21 arrived in 2021, with a 6.2 inch Dynamic AMOLED 2X display and the Exynos 2100 chip. Charging is over USB-C and it unlocks with an ultrasonic fingerprint reader under the display. It is rated IP68. The camera housing wraps into the corner of the frame, and the back is a composite Samsung calls Glasstic rather than glass. That composite back is the quickest way to tell an S21 from an S21+. The one sold in Ireland is SM-G991B.

What this fixes
The faults a battery replacement puts right.
- 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.
- 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.
- The percentage jumps aroundThe gauge has lost track of a cell whose capacity has changed. It is the battery rather than a software bug.
- Charging stops well short of a hundred percentSometimes battery health management doing its job, sometimes the cell. Worth checking which before replacing anything.
- The phone is hot on the back doing very littleA cell working harder than it should. Heat and short life travel together.
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 phone is dead and will not power on at all
Start with a diagnostic rather than a battery. A dead phone can be the battery, the port or the board, and we would rather find out before you pay for a part.
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.
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?
Two tiers, and you choose knowing which is which: a genuine Samsung service part where one is made for this component, or premium aftermarket where none is. The warranty is 360 days on either.
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
You will not find work on the bill you did not agree to. If something else shows up while the phone is open, we stop and ask rather than deciding for you.
If getting here is the problem, we collect and return across Dublin from Monday to Friday. It costs the same repair price and carries the same 360-day warranty.
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
Book online in about two minutes, or walk in without an appointment. Describe the symptom rather than the repair, it is more useful to us.
Free diagnostic
Before a part is ordered we establish what has really gone wrong. It is free, and it is the reason people do not leave here having paid for the wrong thing.
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
It stays in the shop. The work is done on our own bench by the technicians who do it every day of the week.
Bench testing
The repaired function and the things around it are checked before we call you.
Back in your hands
Collected from Drumcondra, or returned to your door if we picked it up. Covered for 360 days.
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.
Health reporting
What the device reports about the new cell, so you know before you leave rather than a week later.
Charge rate under load
Measured with the phone working rather than idle, because that is where a weak cell shows itself.
Temperature during charge
A new cell that runs warm is a new cell we do not send out.
Is anything on the device at risk?
This is hardware work. We do not need to go into your photos, messages or accounts to do it, and we do not.
We do need to switch the device on and use it to test the repair, so we may ask for your passcode. If you would rather not hand it over, tell us and we will show you what we cannot verify without it. Any passcode you give us goes on the paper docket and the docket gets shredded. It is never stored in our system.
Back the device up before any repair. Not because we expect to lose anything, but because a device that has already been dropped is one whose storage has already been shaken, and a backup costs nothing.
Is it still water resistant afterwards?
After any repair, ours included, work on the assumption that the device is no longer water resistant.
The rating on the box was measured once, on a sealed unit, in controlled conditions. It was never a promise about the device three years later. Adhesive hardens, seals compress and a single drop can break the seal without leaving a mark you would notice.
We reseal with fresh adhesive and it does a real job: rain, splashes and a wet counter are all fine. A submerged phone is not, and we would rather say that plainly than let you find out.
If yours goes near water regularly, say so at the counter and we will tell you what the adhesive covers and what it does not.
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.
No. This is hardware work and we do not go into your photos, messages or accounts. Back the phone up before any repair as a matter of course.
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.
It can, and not because the battery is a speed part. Phones slow themselves down to avoid shutting off when a cell can no longer deliver peak current. Replace the cell and that throttling stops.
Treat it as urgent. Stop charging it, stop using it, and do not press on the back or try to lever the phone open. Bring it in and we will deal with it properly.
No. Checking is free and so is telling you it does not need replacing, which happens more often than people expect.

Customer reviews
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!
Caz is a legend gave me a good deal looked after me good fella thanks mate
Bought a phone at imend, Drumcondra, near DCU. What could have been a difficult experience for an untechical minded person like myself was made so easy by the very helpful staff member who ensured my phone was up and running smoothly with everything working well before I left the shop.
Very good customer service very good products I recommend
