So much for using airplane mode to conserve battery.

Your understanding is slightly off.

Airplane mode Does In Fact Turn off your CELLULAR Radio This radio is what powers your (2/3/4/5)G and LTE (This is 4G btw) connection to the cell towers.

Most international radio communications laws can prohibit the use of Cellular Radio in flight; however they often don’t prohibit the use of shorter range radio technologies such as WIFI or Bluetooth.

It’s all about ‘loudness’. Think about it. Your phone must ‘scream louder’ at a farther away cell tower than it would need to communicate with a nearby WiFi router or a Bluetooth headset.
