Foreign media test mobile phone Bluetooth power consumption: almost no effect
Regarding the issue of whether the Bluetooth of mobile phones is always on to speed up power consumption, the foreign media AndroidAuthority conducted a test using Samsung Galaxy S20+, Huawei P40 Pro, ZTE Axon 11, Xiaomi Poco F2 Pro, and Realme X3 superzoom and other models are divided into two groups for comparison experiments.
The first test scenario is the battery consumption under normal daily use. IT Home understands that two groups of mobile phones are divided into one group to turn on Bluetooth and one group to turn off Bluetooth. Each group performs three different operations. The first link is to manually refresh the webpage for 90 minutes, 90 minutes of standby, and to refresh the webpage for more than 90 minutes again. The second link is a 16-hour standby, and the first link is repeated in three links.
The second test scene is 4 hours of continuous video playback. The report only mentions the three stages of operations from turning off Bluetooth, turning on Bluetooth, and connecting to Bluetooth devices to play, but the specific duration is not mentioned. In this test, the screen brightness of all models is set to 200nit, and all functions (data, NFC, etc.) except for the test factors are turned off.
Finally, AndroidAuthority gave the average power consumption of 5 models after a series of tests. The results show that the average power consumption for 26 hours is 49.4% when Bluetooth is turned off, and 51.2% when Bluetooth is turned on.
According to the report, the difference in power consumption between the devices used in the test is extremely small. The difference between Huawei P40 Pro and Xiaomi Poco F2 Pro is 3%, and the difference between Samsung Galaxy S20 and Realme Superzoom is almost the same. AndroidAuthority finally concluded that turning on Bluetooth has little impact on power consumption and has almost no impact on battery life. However, when users perform high power consumption operations, it reduces the impact of Bluetooth alone on overall power consumption. Users do not need to worry too much about whether their Bluetooth is turned on or not.
