I made an app called "Battery Detective".. its in the Market. It monitors temp also and will notify you if it gets hot. It wont tell you what is making it hot, but it'll warn you.

 

That's very interesting! I'm wondering if the temp sensor is in the battery and the one you have is bad... must be.

 

It's a good thing I added a temp <=0 check or it would have never even reported... I'm going to add a special error message of temp < 0 as it should never report that (unless you leave it in the freezer!)

if(fltTemp >= TEMP_THRESHOLD_F || temp <= 0){
...
}

 

Yeah, it sounds like the temp sensor in the battery is bad...

Try putting the stock battery back in and see if it works correctly.

 

You are not the first to have this problem. I remember reading either on this forum or another, that someone had the same flashing light telling them that the phone was overheating. Swapped the batteries back to the stock, and everything worked fine for them as well.

 

I just had this problem (amber/green alternating lights). I guess I can't play Homerun Battle 3D while the phone is on the charger.....

 

the only time my DInc got warm was when I played Air Control for 3 hours.

 

My Inc was very hot last night when it was attached to my PC; I thought there was something wrong with the phone or battery. I plugged it into the wall and it charged without any problems or overheating. Not sure why that happened while connected to my PC.

 

This happens with my incredible off and on using the extended battery.

 

My Incredible overheats easily too. Also, I use the battery indicator pro app but there is a free version too, it tells you the temp and battery life, like if it's good or bad or needs replacing(like a macbook battery), also it gives you the % of the batt life and you can color the battery, just a neat app.
