Likewise, people ask, does NFC drain your battery?

Using NFC affects battery life, but having NFC on effects battery life to such a minor degree that you wouldn't even notice. Unless you use NFC many times throughout the day, having it enabled won't have a huge imparct on battery life.

One may also ask, do NFC chips need power? NFC tags are passive devices, which means that they operate without a power supply of their own and are reliant on an active device to come into range before they are activated. In order to power these NFC tags, electromagnetic induction is used to create a current in the passive device.

Similarly one may ask, does NFC or Bluetooth use more battery?

NFC is much slower and also has a very short range. It utilizes a low-power radio transmitter/receiver, and therefore doesn't affect the battery of the device much. Even though Bluetooth consumes a low amount of power, it is still a sizable chunk as compared to NFC.

Should I keep NFC on or off?
