Samsung: battery draining far too fast
Galaxy batteries are glued in behind the back glass, so a replacement means removing the back panel under heat and fitting new adhesive. It is a longer job than an iPhone battery and worth booking rather than waiting for.

What causes it
- A cell past its rated cycle life, which is most cases
- A background app or a failed update holding the device awake
- A charging circuit drawing current it should not
- Cold weather, which temporarily exaggerates an already weak cell
What to do right now
- Check the health reading if your device has one
- Note whether it shuts down with charge still showing, which is the important one
- Look for the device being warm when you are not using it
- If the back or screen is lifting, stop charging it and bring it in
What we check at the bench.
- Cycle count and actual capacity against rated capacity
- Current draw while idle, which finds a device that is not sleeping
- Whether the charging circuit is behaving
- Physical condition of the cell, because swelling is a safety issue

Battery Replacement starts from €35 depending on the model. No fix, no fee, so if we cannot repair it you pay nothing.
The usual signs are a charge that drops in steps, shutting down above 20 percent, only working while plugged in, or the back of the case lifting. If the device is also slow and hot, bring it in for a free diagnostic rather than guessing, because a failing charging port looks similar from the outside.
Treat it as urgent. Stop charging it, stop using it, and do not press on the back. A swollen cell can split. Bring it in and we will remove and dispose of it safely the same day.
A new cell should hold a normal day of use and stay above 80 percent of its rated capacity for several hundred charge cycles. The 360-day warranty covers a cell that fails early.
The usual signs are a phone that dies well before the end of the day, one that jumps from 30% to nothing, or one that shuts down in the cold. If it is instead getting hot and draining while idle, that can be software, and we check that first rather than selling you a battery.
With a genuine part, yes, exactly as before. With other tiers some iPhone models show a service message next to the battery figure. It does not affect how the phone works and we tell you which you are getting before we start.
It needs dealing with rather than panicking about. Stop charging it, do not press on it, and bring it in the same day if you can. A swollen cell pushes the screen up from behind and will crack it eventually, which turns one repair into two.
Two to three years of ordinary use before you would think about it again, which is what the original managed. Heat is what shortens that more than charge cycles, so a phone that lives on a car dashboard has a harder life than one that does not.
On models where the reader is under the display it is part of the screen assembly, so it is replaced with it and calibrated afterwards. We test it before handing the phone back. On models with a side-mounted reader it is untouched.
Yes for ordinary screen, battery and port work. Knox is a security flag tied to the software, not to these parts, and normal hardware repairs do not trip it.
Yes. It makes no difference where a device came from, whether it was bought here, abroad or second hand. Bring it in.
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!
