Re: heat + power drain in wifi adhoc?

Thats been going around for awhile now and its completely incorrect. The USB port has enough power to run the phone with wifi and EVDO just fine. Whats happening is the phone is overheating. Its a well known problem.

The mogul generates alot of heat. The battery has a thermal cutoff in it. When it gets to hot, the battery stops charging and the yellow light starts blinking.

It helps if you take the back off the phone and open the keyboard to help the phone cool. If you set a fan blowing on it,it fixes it almost completely. (I'm trying to get a fat back battery cover so that I can mount a 4mm thick fan I bought on the battery to solve it once and for all. With a temperature switch,it wont even drain the battery as it will only run when the battery overheats on the charger)

You will sometimes find that the phone overheats and then you let the phone cool off,take the back off and open the keyboard,but it still has problems. Whats going on here is that the battery is already discharged. Charging the battery generates even more heat. The heat from the phone,plus the wifi plus charging is too much and the phone stops charging again.

Sometimes this even happens when the wifi is off depending on the ambient temperature,but its not as common. I suggest you complain loudly. Its unacceptable that the phone was release like this. It just dissipates to much heat. In fact,if the battery is dead,it can have this problem just taking on the phone which is rather irritating. Who ever heard of a phone that you cant plug into the charger when the battery goes dead to keep talking. Ive send mine back twice for overheating and they keep sending me another phone. My hope is that I can talk them into upgrading me to the new model after the sixth or sevent replacement. =)
