iPhone charging ** attract attention, thermometer test iPhone charging body temperature

Recently, "fire" is not just Apple's new ipad, but also iPhone. The temperature of the new ipad is 10 degrees higher than the ipad 2, which has attracted many people's attention. The recent iPhone4 mobile explosion in the United States has attracted people's attention and has caused heated discussions.

A 51-year-old woman in the United States charges her iPhone 4 phone in her bedside table, but in the morning she was awakened by a "puff". In the room, there was a burning odor of plastic burning. The iPhone 4 was smoking and the surface of the phone was Cracked, she immediately dropped the phone into the sink. Although Apple has not yet made an official assessment of this issue, people have already speculated.

It is speculated that the iPhone's spontaneous combustion may be related to the battery. Is it due to the high body temperature of the iPhone? Based on this, people have done a small experiment to explore how high the body temperature of the iPhone is when charging. In general, mobile phone heat is emitted from the battery and the chip. The charging and discharging of the mobile phone battery, long-time phone calls, and long-time processing of data will cause the mobile phone to heat up.

In the experiment, three iPhone 4S phones were tuned into flight mode, one was normally charged during sleep, one was playing while charging movies, and there was a game while charging. In order to ensure the accuracy of experimental data, the mobile phone is in a suspended state. Then using an infrared thermometer to test the temperature of the mobile phone, the initial temperature of the three mobile phones are between 22 °C ~ 23 °C.

However, after 5 minutes, the measurement results are different. The mobile phone that normally charges and plays movies increases the temperature to about 25°C, while the mobile phone that plays the game while charging reaches 30°C. After 10 minutes, the temperature of the normal charge and play movie cell phone rose to about 27°C, and the cell phone that was playing while charging was 39°C. This has to be said to be a surprising temperature, when the original mobile phone was able to reach this high temperature! Industry insiders also stated that under normal circumstances, temperatures around 40°C will not cause the phone to explode. However, when the mobile phone explodes while charging, it is likely that the high temperature has damaged the mobile phone line and a short circuit has occurred.
