iPhone 4 Running Hot When Low Signal

When in an area where reception is low and especially when very low, the iPhone will be warmer since it is working harder to find and maintain cellular reception which will also be big battery drain. When you will be in an area for an extended period of time where you know reception is very low or non-existant, best to enable airplane mode during that time. If there is an available wi-fi network when doing so, you can enable wi-fi access after doing so. When leaving the area, turn Airplane mode off.

Allan, thanks for the tip. I suffer from a similar problem with my iPhone 4 running hot. iPhone 3GS running iOS 4.x did not suffer from that problem.Airplane mode turns off cellular functionality. One of the reasons I bought the iPhone 4 is to use it like a phone. Are there any other solutions? I notice that not everyone with an iPhone 4 has this problem. Is it possible there some hardware units have a defect?

Have a week-old iphone 4. Twice in the past couple of days the phone started to run really hot and then the battery discharged from full to no charge. Once was in a conference center the second time was in a movie theater.
