Literally. I carry it around in my back pocket and if I've had it there for a few hours my butt starts to hurt, but it stops after I take the phone out of my pocket.

My sister has it worse as touch screens make her fingers burn. I've only had that happen a cople of times.

I don't think these are good things.

Yikes, what phones are you using?!?! That's not right.

I've lost the touch sensitivity in my right upper leg which is where I used to pocket my phone. My doctor did not attribute it to cell phone usage, but I'm not so sure.

I do know that once in a while my iPhone goes on a bender and gets hot and burns down the battery like it's going out of style. I'm sure this is a bug that Apple has had since the beginning of time (or it's planned obsolescence), but the fix is to shut it off and then restart it when you notice it happening. Otherwise, it'll run down the battery to nothing and then it's fixed when you recharge.. The phone stays hot for about 5 minutes since it takes that long to cool down.

I have Samsung now, and the one previous was Samsung. Not sure what sis has. I've had the Kindle make my fingers burn. Phone might but I don't often go on the 'net with my phone so don't have my fingers on the Samsung touchscreen much.

I wouldn't be so sure about the cause of that leg numbness either.

Especially since I carried lots of analog phones in that pocket too when things were lower frequency and higher power. I dunno... I've had this conversation with GAD and he thinks I'm probably wrong about the effect of cellphones, but I'll be honest... I did NOT carry one before I had my children. And, on that note.... 'nuff said.

Husband accidentally ran over his with his F250, mashed it into the dirt. It was in an Otter Box and although unconcious when he found it was resuscitated and survived unharmed. That was years ago; he's still using it.

Otter Boxes must be pretty good.

Cynthia,
I'm glad you explained in the text exactly where you were storing the phone, because from the thread title, I was really confused as to its location.

Are you saying the cell phone is getting hot? Or that your body is having some reaction to it?

Cell phones get hot when the CPU is used a lot or when the radios transmit on full power (or when you leave them on the dashboard in a hot car).

CPUs running hot is almost always an app problem. Turning it off and on again kills all the running apps and is generally a sledgehammer approach to troubleshooting.

Radios transmitting at full power are usually the result of the phone being unable to find a signal. By law a transmitter must transmit on the lowest level necessary for proper function. When a cell phone can’t find a tower it broadcasts on full power until it finds one. If you know you’ll be in a no-service area put your phone in airplane mode and the battery will last much longer. Similarly if you’re not using bluetooth or wifi turn those off and marvel at your battery life.

Using the GPS live will consume CPU because whatever app is using it doing a lot of math AND is probably streaming map info in real time from somewhere.

And when you turn on the flashlight function and forget about it ;-)

The RF emitted by a good and properly operating cell phone is minimal, as is the magnetic field around it. The heat generated by the battery charging or discharging, and the heat generated by the CPU running hard could be enough to be an issue. As GAD noted above Airplane Mode or having WiFi and Bluetooth off if you do not need them will keep the battery happier longer.
I would also recommend that if you manage to shock your cell phone hard (impact, drop, etc.) you pay close attention to its temperature over the next 30 minutes or so, as a damaged battery may take a while before it gets hot enough to really be noticed. If you notice it getting really hot, get it away from yourself and anything flammable because it can get hot enough to ignite other stuff before it ignites itself.
