How to keep your BioSense at its normal operating temperature

Our devices have a set temperature range, where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the device's lifespan or performance. However, if your devices get too warm, it could cause some issues. Use this guide to help keep your devices at their normal operating temperature.

Please note: Results and symptoms may vary depending on the device and model being used. Some instructions will not apply to certain devices.

Factors that may impact temperature

  • Check out the Battery’s useful tips (below) on safe usage for more information. 
  • Factors that can affect your device's temperature: 
  • Using your device outside of normal operating conditions, which are ambient temperatures between 32 and 95 degrees Fahrenheit. 
  • Placing your device on or near a heat source, leaving it in a parked car on a hot day, or continual use in direct sunlight. 
  • Using multiple functions for an extended period of time, or using processor-intensive apps such as GPS tracking. 
  • Charging the device with an incompatible, or defective charger (and USB cable) 
  • Initial setup and data transfer from a previous device. 
  • System or firmware updates.

What to do if the device feels too warm

  • Here are some tips for what to do if your device warms up: 
  • Disconnect the charger, and close any running functions until the device cools down. 
  • Try using a different charger (and USB cable) when charging. Be sure to charge the device on a hard, flat surface. 
  • Keep the device's software and apps updated to the latest software version. 
  • Do not use or wear the device until it cools down completely. If the device is still too warm to touch, you should contact support.
