We need to understand the latest progress of Bluetooth technology, there are two kinds of Bluetooth in daily life: traditional Bluetooth and BLE (Bluetooth Low Energy). Traditional Bluetooth uses point-to-point communication, which is usually used in scenarios where the amount of data is large and the connection needs to be continuously maintained, and is commonly seen in audio devices such as Bluetooth headsets and audio speakers.

Does leaving Bluetooth on for a long time make your iPhone more power-hungry?

BLE is a low energy Bluetooth technology, compared with traditional Bluetooth, BLE's biggest advantage is that the search and connection speed is very fast, low power consumption, BLE to complete the connection only about 3 ms, the task will be quickly switched to the non-connection state after completion, the maximum degree of reduction, but BLE physical bandwidth is only 1M. The data transmission rate is low, and BLE is generally used for devices with high practical requirements, but very small data packets, commonly found in devices such as keyboards and remote controls.

Turning on the Bluetooth switch in the unconnected state of the iPhone consumes almost negligible battery power for the phone.

Whether it's commuting to work, stopping the subway, or even wireless office work, Bluetooth technology has made our lives more convenient.
It's not really that power-hungry. This is related to the age of your iphone, the phone you just bought does not consume much power, but compared to wired headphones, wireless headphones are still slightly better
