Nest gen 2 not holding charge

[LR]

I have a nest thermostat gen 2. It was working fine then all of a sudden started disconnecting and could not connect with the app. After a couple days it said low battery and could not connect to wifi. So I took it off and plugged it in via a usb cord. After sitting on the charger all night I put it back on the wall. Within a couple hours it “died” again and was non responsive. I’ve charged it 4 or 5 times at this point and continue to have the same issue. Now I can’t even get it to respond and turn on the heat.

(I don’t not have a c wire)

Hey LR,

Sorry for the late response. I wanted to follow up and ensure your device is working properly from here. Please let me know if you are still having any trouble with the device not holding a charge, as I would be happy to take a closer look and assist you further. 

Best regards,
Jake

Same-ish problem,  

Since an update on November 2nd my less than one year old gen 3 Nest Learning Thermostat has now stopped working three times now due to a battery /charging issue.  The first two times it actually charged on my desk using its USB port. 

When connected to its base and I check its "Power" readouts though its settings menu it shows:

Battery - 3.852 V

Vin - 32.45 V

Vout - 32.45 V

lin - 200 mA(c)

All appear to be expected readouts.

It will no longer charge at all a green LED blinks constantly and the screen displays "Please attach the display to its base".

Prior to Nov 2nd it worked flawlessly.

(I DO have a 'c' wire)

I am following as I am having the same issue.  Was there a software or firmware update or something?

Msjobax> Am not sure what happened.  Got ahold of Google and they are sending me a replacement thermostat.

[LR]

How did you get ahold of them?
