A Google Nest thermostat typically indicates it needs to be replaced when it exhibits chronic hardware failures, such as persistent battery charging errors (battery draining to zero despite wiring), complete failure to connect to Wi-Fi networks due to fried internal wireless chips, uncalibrated temperature sensor drift exceeding several degrees, or a permanently frozen display screen. If resetting the unit, recharging the battery via USB, or re-seating the baseplate fails to resolve recurring power faults, the internal solid-state components have degraded beyond repair. Verification: Check the technical voltage and battery power metrics in the thermostat settings menu to confirm if the device can maintain stable power.
