How exactly can the phone be cold before it stops working? For help, I called our friends at Environ Laboratories, the Minneapolis Environmental Inspection, which is used by defense, aerospace, and technology industries to simulate extreme conditions. Our environment is a mobile phone model from six different manufacturers. The basic models were the raw material categories that providers often sell for a new contract for free – none of them "carpets" or resisted extreme temperatures. The work on the environment was that the devices could be frozen in a temperature controlled chamber (lowest setting: minus 100 F) until all six phones were down – no matter how cold it is.
In other words, we've decided to go beyond these phones beyond the limits of design parameters and warranties.
Starting at 40 F (which is a sharp autumn evening in New England), let every phone run for 30 minutes before setting a temperature of 10 degrees. This incremental temperature drop is repeated every half hour until the phones stop. After the phone died, it was a last pardon that we returned to the room temperature to see if it could be hot for a lifetime.
Apart from the smaller wrists (mild shielding, slow key response), one of the phones did not have a real problem of minus 10 F when the low charge indicator appeared on a Samsung despite being recently uploaded. At minus 20, the same phone stalled (switched on and switched on quickly) and it was difficult to read other phones. Thirty below, where the fun started, five of the six phones that were facing a serious battery or LCD problem – the Nokia display has become a blue-read block, while bizarre tracks have contaminated another phone screen. Up to 10 degrees, minus 40, and all but one phone does not work. The last phone was standing, an old Motorola Krzr, which belonged to a PM box, actually worked, while the battery was down. It is noteworthy that none of the damages seemed to be durable – all of this was taken back to room temperature so that all the phones would come alive. Yet, the electronic sadist, and we did not allow him to access the Environment Environmental Testing Facility – and his liquid nitrogen tanks.
Of course, the coldest temperature in the world was only 12.6 F (and the continental USA never dropped below 70), but we could not resist finding our hardest competitors in a minus 314.7 F bucket liquid nitrogen. Surprisingly, the Motorola phone survived the reprocessing of the coolant, and the secondary bottom zero swings caused the battery to be discharged, but after the phone warmed up, the damage was again visible. The frozen phone was also lowered from the hip height to the floor. And while we waited for it to break, the fall had hardly caused any damage. In fact, we only did so until the Krzr was hit four times in liquid nitrogen and then cut it through the force and finally we called it. Even when the phone was on (though it was unreadable), the screen was still on and the audio was still amazing. However, some keys seemed to answer
The results were reassuring, if not surprising. At the bottom station, Alaskan residents may have some screen problems or short-lived batteries on cold days, but no warm-room can cure. And if your phone can handle repetitive swimwear in one of the coldest fluids in the earth, yours can survive on sunny days without worry.
