Battery Temperature

I have the BatteryLife widget and it has an option to show the temperature of the battery (it may not be 100% scientifically accurate but I'm sure it's close). Usually my battery sits around 70 degrees when it's not being used. Last night I was talking on the phone for a little over an hour and I noticed it was getting pretty hot. After I ended the call I looked at the BatteryLife widget and noticed the temperature was at 107 degrees. Is it normal for a battery to get this hot after talking on the phone for just an hour?
 
Short answer: yes.

Longer answer: The temperature is elevated when current is flowing. More current (more phone usage) more heat. The CPU and other processors also generate heat and they are pretty close to the battery. CPU intensive processes and GPS as well as other sensors use current and heat up.

108f is about the highest I've seen on my Droid with the same widget. It is normal during use to see it go high.

Thanks for the quick reply! Just wanted to make sure I don't have a crazy battery/phone

That seems uncharacteristically high for a battery. There are factors to consider though:

-Warm batteries or phones stored in pockets etc tend to shorten the life of the battery even when fully charged. This is just inherent to lithium ion polymer tech
-Those widgets may not be 100% accurate in the temperate reading

Did you have the phone plugged in while talking? Sometimes that can cause it to be hotter than normal.

It wasn't plugged in.

I was browsing the web for a bit and I can definitely feel it warming up.. the keyboard also around the left side gets pretty warm too.. it got really hot on the back right between the camera and google words on the back.

I'm gonna use it for a while and see how long it takes and how hot it gets. If it starts to heat up way too much ill get another droid. I've got a build date of 45/09 too I think
