RTC DS3231 Not resetting time on power loss

Question

I'm completely removing power from a DS3231 RTC module and my call to rtc.lostPower() is never hit when I reconnect everything. I'm also removing the battery, I left it overnight and it remembers the time just before I disconnected everything, but doesn't register a power loss. I'm using this with a D1 mini.

void setup() {
  // put your setup code here, to run once:
  Serial.begin(baud);

  if (!rtc.begin()) {
    Serial.println("Couldn't find RTC.");
    while (1); // while true
  }

  if (rtc.lostPower()) {
    Serial.println("RTC lost power, resetting time.");
    ConnectWiFi();
    GetNtpTime();
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    Serial.println("Time set after power loss");
  }
}
