Is Australia About To Cop A Big 5G Heat Problem?

Is Australia about to cop a major 5G heat problem with tests in the USA revealing major problems with 5G handsets.

In the USA it’s summer and in some Cities where it’s 37 + degrees researchers have found that certain 5G smartphones are not reliable in the heat.

One of the products exposed is the Samsung Galaxy S10 5G which is being sold exclusively by Telstra.

According to Wall Street Journal journalist Joanna Stern When she ran test of the Samsung offering, the phone’s 5G network often switched off due to overheating, leaving me with a 4G connection. Apparently, carriers in the USA have taken to trying to cool the 5G handset devices with ice packs and air conditioners.

The phone does this when the temperature reaches a certain threshold to minimize energy use and optimize battery, a Samsung spokeswoman said. “As 5G technology and the ecosystem evolve, it’s only going to get better,” she added.


A Verizon 5G test in Denver, conducted using Ookla’s Speed test app, hits 1,500 megabits per second a far cry from the measly 360Mbps second that we have been able to achieve on the Telstra network metres away from a 5G tower.

The journalist embarked on a 5G expedition from Denver to Atlanta to Chicago to Manhattan’s Lower East Side. She mostly used the new, $2,300 Samsung Galaxy S10 5G, one of the first 5G phones. She also tested the LG V50 ThinQ 5G.

“Holy spit!” I said the first time I saw a speed test hit 1,800 megabits per second on Verizon’s network in downtown Denver.

That’s 52 times the average 4G network download speed according to internet speed-test company Ookla who also power the Telstra Speed Test site which is only delivering results below 400Mbps in Sydney and Melbourne where we have tested the same Samsung smartphone which in the USA is powered by Millimetre-wave 5G technology.

At times when the 5G would stop working, an infrared thermometer showed the back surface of the phone was over 100 degrees.

“With 5G, data is transmitted at higher quantities and speeds, which causes the processor to consume more energy,” the Samsung spokeswoman said.

It isn’t atypical for a phone’s processors or modems to reduce functionality when they are heavily taxed or overheated. I put the phone through some intensive tests—although nothing I couldn’t imagine any power user doing.

Stern wrote ‘I was surprised, though, when in my tests even a simple download on a normal summer day could overheat the phone and sever the 5G connection’.
