This Free Android application will display the battery temperature of your Android phone or tablet in degrees celsius and fahrenheit. It will work on almost all devices. Used to monitor battery temperature for battery care or other scientific purposes like research. The battery temperature will give a good overall indication of the phone temperature. If the phone is drawing little power from the battery and is not charging the battery temperature indicator will be close to room/ambient temeprature. Like when it is in flight mode and not doing much.
