iPod nano overheats

The Japanese industry ministry is reportedly investigating an incident in which an iPod Nano "overheated and discharged sparks." Reuters quotes the ministry "The battery part of the product overheated while being charged and sparked," Apple's iPod safety manual states "When you're using iPod or charging the battery, it is normal for iPod to get warm. The exterior of iPod functions a a cooling surface that transfers heat from inside the unit to the cooler air outside." As such, iPods have been known to overheat when placed in cases that do no allow adequate ventilation.

    Let's think about this. Plastic? Insuulator. Rubber/polymers? Insulators. Metal? Conductor. Cloth? Possible ventilation.

    So, out of these five most-commonly used matierials for iPod skins and cases, only two let heat dissipate, yet the other three are the most commonly used for their cushioning, inexpensiveness, and rigid properties.

    Word to the wise- if you want the storage media and battery in you iPod/iPhone to last longer, keep it cool.

    cool water

    soaking it in cool water is fine, but you should always put it in the freezer after a good soaking to keep it cool.

    cool quick charge

    adding salt to that 'cool' water will help too! and if you want to quick charge your iPod to limit the 'heat exposure' time to the battery you can take a regular extension cord, chop the end off, and drop it in the salted water your iPod is sitting in.
