Samsung overheating

Galaxy phones throttle hard when hot, so a phone that feels slow and warm together is usually one problem rather than two.

What causes it

  • A battery at the end of its life, which generates heat charging and discharging
  • Dust in the cooling path on anything with a fan
  • Thermal paste that has dried out, on laptops and consoles more than three years old
  • Something running in the background that will not sleep

What to do right now

  • Note whether it is hot while idle or only under load
  • Take the case off and see whether it still happens
  • On a laptop or console, check whether the fan is audible and whether the vents are clear
  • Stop charging it if it is hot enough to be uncomfortable to hold
The diagnostic

What we check at the bench.

  • Idle current draw, which finds a device that is not sleeping
  • Battery temperature and condition under load
  • The cooling path, on anything with a fan
  • Board temperatures under a thermal camera where the cause is not obvious

Common questions.

A battery at the end of its life, which generates heat charging and discharging. Dust in the cooling path on anything with a fan

We quote it after a free diagnostic, because the price depends on what we find. No fix, no fee, so if we cannot repair it you pay nothing.

On a laptop or console that is almost always dust packed into the heatsink, plus thermal paste that has dried out after a few years. Both are serviceable. Left alone the heat shortens the life of everything around it.

That points at the battery or something drawing current it should not. Worth a free diagnostic rather than waiting, particularly if it is also losing charge quickly.

4 Richmond Road, Drumcondra, Dublin 3, D03 FX52, a few minutes from Drumcondra train station and on several bus routes into the city. There is parking on the road outside.

Yes, anywhere in Dublin, Monday to Friday. Tell us where you are and we arrange a time. Outside Dublin we are not set up for collection, so the device would need to come to the shop.

Most of the time, yes, if we have the part on the shelf. That covers common iPhone and Galaxy screens and batteries. Ring ahead on 085 200 1155 with your model if you are coming across the city and want to be sure.

For common faults on common models, yes, and the price is on the page you are reading. For anything with no clear symptom, liquid damage especially, nobody can price it honestly without opening it, so we do that for free first.

No. The diagnostic is free whether you go ahead with the repair or not, and that is true for the quick check at the counter and the longer one on the bench.

That depends on what the device is worth and what the repair costs, and we will tell you honestly when the sums do not work. Turning away a job we could have charged for is the reason people come back.

You pay nothing. No fix, no fee covers the diagnostic and the handling, so the only time you pay is when the device comes back working. If a repair turns out to cost more than the device is worth, we tell you that instead of doing it.

Yes, with collection across Dublin, an invoice rather than a counter payment, and a single contact rather than a queue. There is a page for that with the details.

Excellent customer service bought my samsung A54 best price in dublin.

Mr MAURICE CaldwellTrustpilot

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!
