The Galaxy S23 Ultra arrived in 2023, with a Dynamic AMOLED 2X display. It charges over USB-C and it unlocks with an ultrasonic fingerprint reader under the display. It is rated IP68. Four rear cameras and the S Pen, with a curved display. Ireland gets the SM-S918B.

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.
  • 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.
  • The percentage jumps aroundThe gauge has lost track of a cell whose capacity has changed. It is the battery rather than a software bug.
  • 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.
  • 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 drains fast but only since a recent update or a new app
Check Settings, Battery for what is actually using it before replacing anything. Software can empty a healthy battery in a morning, and a new cell will not fix that.
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?

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.

The words genuine and Samsung certified mean something specific and we only use them when they are true of the part in front of us. Anything else is described as premium aftermarket, plainly.

  • 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.

Genuine, OEM and aftermarket: what the words actually mean

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.

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.

iMEND Premium

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.

€85

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.

€80

The €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.

The parts we use, in full

How we do it

From the counter to back in your hand.

Tell us what it is doing

Walk in during opening hours or book ahead, whichever suits. Tell us what the device is actually doing rather than what you think the fix is.

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

Done at our Drumcondra bench by the technicians who do this every day.

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

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.

Current under load

Checked while the phone is working, which is where a bad cell shows itself and a resting one does not.

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.

What happens to what is on it?

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.

Asked all the time

Galaxy S23 Ultra screen questions.

€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.

Rarely, for a battery. A battery is the cheapest repair that makes an old phone feel new, and on most models it costs a fraction of a replacement handset. If we think you would be throwing good money after bad we will say so.

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.

Some manufacturers pair the cell to the board and show a notice after any replacement, genuine or not. Everything works; it is a parts message. We tell you in advance if your model does it.

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.

iMEND is an independent repair service. Brand and model names are used only to describe the devices we repair. We are not affiliated with, endorsed by or an authorised service provider for any manufacturer.

Why bring it here

An independent workshop, not a kiosk.

We are a dedicated repair bench in Dublin 3. That means we take on work authorised channels turn away, and we tell you honestly when something is not worth fixing.

Diagnosed, not guessed

Every device is tested before we quote, so you are not paying for a part that was never the problem.

Parts that last

Genuine or OEM-grade components chosen for your model. We tell you which is going in before we start.

Your data stays yours

Hardware-only repairs. We never read, copy or move anything on your device.

No fix, no fee

If we cannot repair it, there is nothing to pay. No diagnostic fee, no handling charge.

Customer reviews

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!

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.
