Hi vincent743,
Thanks for visiting here in the Google Nest Community forum. We're sorry for any trouble this may have caused you. I wanted to look deeper into this and check why your Nest Thermostat is getting blacked out or shutting off. You can charge the Nest Thermostat via a micro USB cable. You can use the USB port on the back of your Nest Learning Thermostat or Nest Thermostat E to charge it up when the battery is low.
- Pull off the thermostat display.
- Plug it into a USB port on your computer or a wall charger like the one you use to charge your phone.
- A blinking light on the front of your thermostat confirms that it’s charging. The color of the light will depend on the battery level of the thermostat when you charge it. Usually, your thermostat will take about half an hour to recharge. But if the battery is fully drained, it can take as long as 2 hours to recharge.
Also, please answer the following:
- Are you from North America or Europe?
- What type of Nest Thermostat do you have?
- Let’s gather the power reading of your Nest Thermostat
For the Nest Learning Thermostat and Nest Thermostat E:
- Press the thermostat ring to bring up the Quick View menu.
- Turn the ring to Settings and press to select.
- Turn the ring to Technical Info and press to select.
For the Nest Thermostat 2020:
- Tap the touch bar to bring up the Menu view.
- Slide your finger down to Settings, then tap to select.
- Slide your finger to Equipment > Power Info.
I look forward to your response.
Cheers,
Renz
