Battery life

[Mrumlewi]

I moved into my home with 3 Nest Thermostats already installed. All 3 worked fine for heating but only 1 is able to control the AC. Since switching to just AC the battery life on the thermostat drains daily. It's a USB charge so I'm having to charge it for an hour plus every day just to turn the air back on. Google support said to disconnect the thermostat from wifi for 24 hours but with the heat and having an infant I am unable to do that. Any other suggestions on what to do or what might be the issue?

Hi Mrumlewi,

Thanks for reaching out. I'm sorry to hear that you're having an issue with your Nest Thermostat. I'd love to know more about this and I have a few questions:

• What type of Nest Thermostat do you have?
• What is the power readings of your Nest Thermostat?
• Could you share the case number of your interaction with our team?

Looking forward to your response.

Thanks,

Edward

Hi Mrumlewi,

Thanks for the response. You could still control your Nest thermostat manually even if it's disconnected to your Wifi. This would let us know if the issue has something to do with poor Wifi connection, and the battery behavior is only a symptom. I'd still suggest doing the step that the representative provided to help us isolate the issue.

Thanks,

Edward

So I did what was suggested and disconnected the thermostat from the wifi for 24hours and still having issues with the battery life.

This initial numbers were Battery 3.771v, Voc 38.73V, Vin 7.22V, and lin 20mA

after 24 hours it was Battery 3.752V, Voc 38.95V, Vin 37.90V, and lin 40mA

Hi Mrumlewi,

Thanks for the update. Based on your description, it's possible that you would need to have a common wire connected to your Nest Thermostat. A common wire is a wire that's dedicated to delivering constant power and stabilizing the flow of current into the thermostat.

Thanks,
