A low battery in a Nest thermostat can potentially cause it to keep changing temperature due to instability in its power supply. 

When the battery voltage drops to a certain level, the thermostat may encounter issues with maintaining consistent functionality, leading to erratic temperature adjustments or unexpected behavior.

 To fix this issue , you’ll need  to replace the batteries with new ones or connect a C wire to your thermostat which is a more stable source of power.

You can adjust the learning behavior settings in the Nest app or thermostat settings to control the frequency of automatic temperature adjustments. Additionally, you can manually set the temperature to override any automatic changes.
