The Galaxy S25 Ultra came out in 2025, with a 6.9 inch Dynamic AMOLED 2X display and the Snapdragon 8 Elite for Galaxy chip. It charges over USB-C and it unlocks with an ultrasonic fingerprint reader under the display. It is rated IP68. Four rear cameras in separate rings, a titanium frame with squared-off corners, and the S Pen in a slot at the bottom. Ireland gets the SM-S938B.

What this fixes
The faults a battery replacement puts right.
- 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.
- The screen or back is lifting at one edgeA swelling battery pushing the phone apart. This one is genuinely urgent: bring it in rather than pressing it back down.
- Battery health well down, or a service messageMost phones report capacity against new. Below about 80 percent most people notice it, and the device may also be throttling to avoid shutdowns.
- 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 phone is hot on the back doing very littleA cell working harder than it should. Heat and short life travel together.
- The case no longer sits flat on a tableA swelling cell, and this one is urgent. Stop charging it and bring it in.
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 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.
IfIt has always been like this since you bought it second hand
Worth checking whether it has been replaced before with a low-grade cell. That is common and the fix is straightforward.
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.
Nobody here will call a part original when it is not. If what fits your phone is premium aftermarket, you hear that word at the counter rather than reading it on a docket afterwards.
- 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 €80 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
No additional paid work happens without your approval. If the diagnostic finds something behind the part we are replacing, we stop, explain it and confirm the cost first.
A collection and return across Dublin can be added when you book. The repair price and the warranty are the same either way.
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.
€80The €80 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
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
The price is confirmed to you before anything begins, and it does not move afterwards unless you agree to something else.
The repair is carried out
Carried out here in Drumcondra rather than sent away, by people who do this repair daily.
Bench testing
Nothing is handed back untested. The repaired part and its neighbours are all checked first.
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.
Heat
Felt and measured while charging. A battery that runs hot from day one is going back out.
Charge rate under load
Measured with the phone working rather than idle, because that is where a weak cell shows itself.
Health reporting after the swap
Confirmed in settings where the device reports it, so you can see the number for yourself before you leave.
Seal and adhesive
Refitted with fresh adhesive so the phone closes the way it did before it was opened.
Is anything on the device at risk?
We are replacing a part, not reading a phone. Your photos, messages and accounts are not something this job touches.
The one place it comes up is testing. A repair is not finished until it has been used, and using a locked device means a passcode. You are welcome to withhold it, and we will tell you which checks that leaves undone rather than quietly skipping them. A passcode you do give us lives on a paper docket that gets shredded, never in a database.
Back it up first if you can. A device that has taken a knock has had its storage shaken whether or not anything looks wrong, and a backup is free insurance against the day that matters.
Will it still survive a splash?
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.

€80, 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.
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.
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.
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.
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.
The battery comes out through the back rather than the front. The rear glass is glued on and has to be heated off first, then resealed with fresh adhesive afterwards.

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!
I had a great experience with the guys, they helped me get started with my new phone, they didn't push me to go for the most expensive items, they respected what I was looking for.
Went in to get my phone fixed last week, great service, friendly staff
Excellent experience with the team in imend. My husband 50th birthday present was a phone charger and holder for your car and it wouldn't stay attached to his Audi dash. The guys in imend put two devices together to get it working. Very happy Hubbie and wife- lovely guys to work with and they even threw in a birthday charging gift.
