Nest Battery Not Holding Charge

I own two Nest Thermostats.  One of my units recently went dead on me.  I plugged it into a cable and it powered back on but only for a short period of time.  I then began reading threads that it could be the furnace or the power supply so I thought to plug it directly into my other NEST cradle only to discover is the unit itself that is not holding a charge and not the power supply or furnace.  The reason I know this, the other unit plugged in to the malfunctioning units cradle is working just fine.

The unit is only a few years old, so I'm wondering if the battery is just completely depleted - if so, is there a way to change the battery or do I now need to invest in a new unit?

Hello gmarkoutsas,

I'm sorry to hear you're having an issue with your Nest Thermostat that won't hold its charge. I'd be happy to take a look at this for you.

The Wi-Fi connection is unstable, the connection between the thermostat and the router has interference, and it may have power issues that have been overlooked for a long time. These are some of the possible reasons why your Nest Thermostat drains its battery. To isolate:

 

  • How far away is the thermostat from the router?
  • Are you getting any wiring reports or message codes in its settings?
  • Do you have a zoned system? 
  • Do they have a common wire connection to provide adequate power?
  • Please gather its power readings in the Technical Info settings.

 

I'll look forward to your response.

Regards,
Mark

The nest is still malfunctioning. Sometimes it works sometimes it doesn't. Looks like I need to replace it. 

Now it won't even turn on even when I directly plug it into a charging cord. Is there some kind of warranty on these things. It's not that old.

Hey Mark.   I am having a similar problem.  I have 2 Nest Thermostats. First one is a 5 wire set up and works fine. Second one is a 2 wire (W1 & RH). The Nest internal battery is only holding a charge for 24 hours. Both have been installed for 8 months and we’re working fine for 7 months. I think the internal battery is bad. I would like a replacement.

Hi everyone, 

 

@Dowro07, thanks for visiting the Google Nest Community, we wanted to look deeper into your case. Please answer the following:

Let's gather power readings of the Nest Thermostat. Follow the steps below:

For the Nest Learning Thermostat and Nest Thermostat E:

  1. Press the thermostat ring to bring up the Quick View menu.
  2. Turn the ring to Settings and press to select.
  3. Turn the ring to Technical Info and press to select.

For the Nest Thermostat 2020:

  2. Slide your finger down to Settings, then tap to select.
  3. Slide your finger to Equipment > Power Info.

I look forward to your response.

My nest learning thermostat randomly disconnected from my wifi 2 months ago, will not reconnect or even recognize any network. Now it won't hold a charge either on the base or by USB. The entire unit quit on us on the coldest weekend of the year! Is there a replacement option? We have had this unit for less than a year!

Hi TrishaD,

 

I'm sorry for the trouble this may have caused you. To confirm, in what country are you located? How long did you charge your Nest Learning Thermostat to a USB charger? 

 

Thanks,

Jenelyn

My nest 3nd has been in  almost seven years. Recently there was a low battery problem, the USB battery could not be charged, but it did not show a black screen. Do I need to change the battery? Or contact customer service directly? Is there a customer service number?

I’m in the same boat one unit works, the other conked out.  I regret buying this “smart” device.  My AC keeps cycling on and off with no way for me to stop it.  Spare me how this saves ANY kind of energy.  Reading the non helpful replies to an obvious crappy product makes my blood boil.  Will be trashing Google nest on every retail site until this is fixed.  Hopefully the contractor who installed this brings me a new unit.  Waste of money!!!
