Learning Thermostat losing charge

[Bruiser]

Hi

I've lived in my unit about 5 years with a pre-installed Nest Learning Thermostat. I've only had to charge the unit about once a year until about 6 months ago when it started to need charge every 4-6 weeks. I have no wire C installed but do have Rc, Y1, G, W1.

Current device info: Battery 3.792V; Voc 36.4V Vin 34.33V Iin 40mA(i)

I have the latest software (just ran a check).

Any advice?

Hey there,

Sorry to hear about the trouble. I wanted to follow up and see if I could be of any help. Are you seeing any error codes on your device? There is a chance you may need to install a C wire/ Nest Power Connector. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further. 

Best regards,
Jake

Hi - No error codes, just that it needs a charge. Once charged it lasts a few weeks, which is a lot less than it used to. WiFi router hasn't moved so I don't think a poor signal is causing the issue (only thing I can think of).

Perhaps the batteries a losing life, like an old cell phone?

Hey there,

There is a chance the batteries may not be holding a charge as well as they used to. You can resolve that issue by installing a C wire/ Nest Power Connector, as this will give constant power to the device.

Best regards,

Jake

Thanks Jake.

Running and Installing the C wire is beyond my skills - I'll discuss with an engineer when next service is due.
