DO NOT PURCHASE A NEST THERMOSTAT
I posted the message below and have spent countless hours with support but Nest refuses to refund my purchase. I paid $300 for the Nest Learning Thermostat and remote sensor and it does not work.
After installation on compatible equipment, the device did not work so I requested an RMA, but continued to work with support to resolve the issue. Nest Support could not resolve the issue after many calls an hours on the phone, the RMA expired, now Nest will not issue a new RMA.
Buyer Beware!

We have had our nest learning thermostat for several years and have had no issues up until about 4-5 weeks ago. It is going offline and shows a low battery message. I removed the unit and charged via a USB but this is only a temporary fix as the batteries continue to drain and only last about 6 hours before having to be disconnected and recharged again .
After searching the support site, I found an article that indicated the thermostat needed to be replaced, so I purchased a new identical thermostat (Nest Learning Thermostat 3rd Generation), and the new thermostat is doing the same thing.
There is power getting to the thermostat, but the battery drains faster that it charges. The wifi seems to shut down when the battery reaches about 3.65v.
Wiring has not changed, nor has the AC unit. Since I now have 2 of the same thermostats, I took one and installed on my second AC unit where I have an Ecobee installed. The same thing is happening on that unit, so it is not the HVAC units. (the Ecobee is now reinstalled and working fine)
Something has changed with the Nest Thermostat recently which is causing this. I would prefer to keep the Nest thermostats, but they simply are not working properly.
I really think this is related to a recent software update. How can a new software bug be reported to Google, and can a rollback to the previous version of software in the device be requested?
Any help would be greatly appreciated?
