Problems seem to be plaguing the newly launched iPhone 4. After several issues with proximity sensors, antenna band and capped upload speeds comes a new issue from several users that their iPhone 4 tends to get overheated even under normal circumstances.
This however seems to be a software problem rather than a hardware issue. Members on the Apple support forum have complained that their iPhone 4 locks them down with a ‘The iPhone is overheated’ message even when it is clearly not. Here are some messages from the Apple support forum
“Today my iPhone was in an air conditioned room and unused for at least 30 minutes. The phone rang and when I tried to answer it I was unable. The display had a large yellow “!” icon and said something about the iPhone being too hot and I’d have to wait to use it.”
“I had this happen as well last night and called Apple support. The phone was sitting idle on a table in an air conditioned room when the message came up.”
Elsewhere on the Mac enthusiast forums
“Today I had my phone in my pocket in sleep mode for, i would say about an hour. I sat down after running around the office and when my pants got a little tight from sitting down my leg felt warm. I took my iphone out of my pocket and it was hot. I put it on my desk and after about 20 min. it was back to room temp.”
Mac website HardMac too notes similar issues. The website points out that the room temperature was only around 25 celsius when the message popped up. Apple has noted in its manual that the iPhone may not be continually used above a temperature of 35 celsius.
