Ring 2 Doorbell poor WiFi RSSI

Hi, My current RSSI is -67dBm which works OK, however if I place my phone in the same position as the doorbell it receives the same WiFi signal at -44dBm. The AP is only 2m from the doorbell (behind a brick wall) and I even created a separate SSID just for ring. 23dBm is a massive difference compared to my phone, is the ring hardware really that bad ?
