5G's Latest Problem: Summer Temps Are Causing 5G Phones To Overheat

from the this-is-all-going-really-well dept

Buried underneath the blistering hype surrounding fifth-generation (5G) wireless is a quiet but growing consensus: the technology is being over-hyped, and early incarnations were rushed to market in a way that prioritized marketing over substance. That's not to say that 5G won't be a good thing when it arrives at scale several years from now, but early offerings have been almost comical in their shortcomings. AT&T has repeatedly lied about 5G availability by pretending its 4G network is 5G. Verizon's falsely telling everyone 5G will help cure cancer, but its actual deployments have been spotty and expensive.

5G device support barely exists. Apple is in no rush to get its first phones to market. The promise of 5G as a competitive and rural coverage panacea has been vastly overstated. And most surveys suggest US consumers (who already pay some of the highest data prices in the developed world) are more interested in lower bills than faster speeds. All of which is to say that 5G isn't quite the Earth-shattering revolution it has been heralded as by carriers and network vendors eager to sell more cell phones and network hardware.

There's another wrinkle being noticed by some of the folks putting these networks through their paces. Qualcomm's first generation 5G modem chipsets appear prone to overheating in summer temps, something oddly missing from the industry's marketing hype. It's a problem that's plaguing numerous carriers, according to Sascha Segan and PCMag:

"On a hot Las Vegas morning, my two Galaxy S10 5G phones kept overheating and dropping to 4G. This behavior is happening with all of the millimeter-wave, first-generation, Qualcomm X50-based phones when temperatures hit or exceed 85 degrees. We saw it with T-Mobile in New York, with Verizon in Providence, and now with AT&T in Las Vegas. It's happened on Samsung and LG phones, with Samsung, Ericsson, and Nokia network hardware."

Current 4G LTE smartphones integrate everything into one chip. Early 5G chipsets require numerous chips including a chip for the 5G mmWave modem and the mmWave antenna modules. As a result, current 5G chipsets take up a lot more room and generate notably more heat than their 4G equivalent. And while better chips are expected to arrive in time, it's another example of how early 5G adoption isn't really worth it, especially given this connectivity is being priced at a steep premium over already costly 4G LTE plans.

Again, faster, more reliable networks are always a good thing, and in time 5G will be an important natural evolution, whenever it's fully cooked and widely available. But the absurd hype we've been subjected to up to this point (5G will cure cancer! 5G will result in four day work weeks!) is actually undermining the technology. Instead of showing consumers why 5G is important, carriers and hardware vendors rushed 5G tech to market, overstated what it can do, and misrepresented where it's available, leaving consumers with the distinct impression 5G is largely just undercooked bullshit.
