Oh dear, seems a few people are suffering burnt body parts from hot iPhones. A lot of complaints are being made about some serious heat issues. You’d think with the new all singing and dancing iPhone only being out a fortnight this issue might just be a firmware bug but it seems its quite a big problem, to which Apple has responded.
If your phone is exceeding “normal operating temperatures” Apple says it can affect phone charging, display brightness and signal strength. If your iPhone gets too hot Apple recommends you 1) don’t leave it in parked car , 2) don’t leave it in direct sunlight and 3) don’t use processor-intensive Apps in hot conditions (ie using the ipod feature in the sun, or using GPS in a hot car)
If the white iPhone discolouration complaint continues (for those who may not know, people have been reporting that the white backed iPhones when getting extremely hot have discoloured the white plastic to a pink colour) may lead Apple to recall its “Jesus” of smartphones.
