Battery Temperature Troubleshooting
Applies to models:
CVR-155-A / CVR-255 / CVR-255-64 / CVR-355-128 (Xplorer) / CVR-655-128 (Xcelerate)
Overview
If your ClassVR headset is frequently powering off during use, one possible cause is elevated battery temperature. Like all lithium-ion battery-powered devices, ClassVR headsets monitor internal battery conditions and will shut down automatically to protect both the battery and internal components when temperatures exceed safe thresholds.
Common Causes of Battery Overheating
Several factors can contribute to increased battery temperatures:
Age of the Battery
- Over time, natural battery degradation reduces efficiency and increases internal resistance, which can cause overheating during charge or use.
Environmental Heat
- Leaving the headset in a hot environment (e.g., direct sunlight, near radiators, inside vehicles) can raise internal battery temperatures significantly.
Improper or Irregular Charging
- Charging the headset with non-recommended chargers or outside of regular cycles can impact battery health.

Use of Incorrect Charging Equipment
- Always use approved USB cables and charging hubs provided by or recommended by ClassVR.
High-Performance Applications
- Running power-intensive applications (e.g., custom APKs, 3D content) can place high demand on the processor and battery.

How to Check Battery Temperature
You can monitor headset battery temperatures from the ClassVR Administration Portal:
- Log in at https://portal.classvr.com
- Click the Settings gear icon (top-right)
- Select Administration Portal
- In the left-hand menu, click Devices
- Locate the relevant device in the list
- Look for the Battery ℃ column
📌 Note:
- The temperature shown reflects the last time the device checked in to the Portal. If it hasn't recently connected, the data may be outdated.
- If the Battery ℃ column is not visible, click the ‘Actions’ pane on the right and ensure it is checked to display.
Best Practices for Preventing Overheating
- Avoid using or charging devices in hot environments
- Use only recommended chargers and cables
- Allow cool-down periods between lessons, especially during intensive sessions
- Take regular breaks every 15 minutes to:
- Allow headsets to cool
- Reduce student eye strain and fatigue
- Avoid running multiple high-intensity apps back-to-back
Final Notes
If battery overheating persists or worsens:
If you suspect a hardware fault, report it via:
