Does the iPhone 7 Bluetooth headset consume a lot of power?

Awesome.

When Bluetooth is turned on and not connected to a device, the increased power consumption of the phone is minimal, while the power consumption of connecting to a Bluetooth device is 2.3 times the normal standby power consumption. The difference between using a Bluetooth connection device to play music compared to a wired connection is 100 milliwatts. The power consumption of using a Bluetooth headset is 1.6 times that of ordinary wired headsets.

Even Bluetooth 4.0 technology, which consumes less power, still consumes more power than wired headphones when used.

Methods to avoid fast battery consumption

1. Pay attention to signal strength

One of the culprits of rapid battery consumption on mobile phones One is to frequently search for weak signals. If you are in a place with poor signal, you can consider temporarily switching to airplane mode to prevent the iPhone from constantly searching for weak signals. In addition, use Wi-Fi as much as possible when Wi-Fi is available. Unstable cellular data will also consume a large amount of mobile phone battery.

2. Turn off background application refresh

Turning off this function will not affect message push. Turning off this function will greatly reduce resource scheduling and consumption to save power. If the APP installed on your phone takes up a lot of memory, turning off this function will have a great effect. Setting method: Settings-General-Background App Refresh, just select to turn it off.

3. Turn off Siri search

This function is rarely used. To some extent, the Siri search function will slowly consume the phone's battery in the background. Just choose to turn it off. Setting method: Settings-General-Spotlight search, just turn it off.
