Logging coordinates with a frequency EVERY 10 seconds is probably the main issue of why your phone overheats. Do you really need to sample that often? Consider the precision of the GPS hardware (the GPS receiver is probably overheating) and the ability of your phone to accurately post your user's position.
You have certainly read how your LocationSensor works and about Accuracy and precision of measurements. The device isn't always where it thinks it is. Asking for a distance of 5 meters in code does not guarantee the device WILL actually post at that interval.
