Will your cellphone make it through the cold of the winter?
At -10 degrees F, the phones started experiencing battery problems. At -20 degrees F, some models started to shut off and those still alive started to show battery and LCD problems at -30 degrees F. From -40 degrees F to -55 degrees F, the remaining phones shut down. The good news is that once all 6 were warmed up to room temperature, all functionality returned to the handsets and there was no permanent damage. The last phone standing was subjected to one last test. Dipped into liquid nitrogen at -314.7 degrees F, this cellphone stopped working only due to battery problems and was revived at room temperature with no lasting damage. According to the magazine, it took 4 dips into the liquid nitrogen and a throw onto the floor before that model suffered irreversible damage. So for those who obsess over every scratch or drop of their cellphone, this test shows that these gadgets are made to withstand freezing cold weather that might bring down a human, but not leave lasting damage to his/her phone.
