After Apple canceled the 3.5mm audio hole in the iPhone 7 mobile phone launched in 2016, True Wireless Headphones began to appear. With many manufacturers launching products under $2,000 and optimizing product functions, True Wireless Headphones have become more popular. Become one of the current overlords of wearable devices. A few days ago, a netizen posted a message asking why the remaining power of the left and right ears of his AirPods are different? Here is an analysis:
True Wireless Bluetooth Headset (TWS, True Wireless Stereo) refers to true wireless Bluetooth stereo. The mobile phone can connect to the main headset through Bluetooth technology, and then the main headset can connect to the secondary headset wirelessly to achieve true wireless separation of left and right Bluetooth channels. use.
In order to avoid the large power consumption of the earphones and the transmission delay problem of the secondary earphones, Qualcomm released the QCC5100 series of Bluetooth chips in 2018, which introduced the function of independent transmission of left and right channels with Bluetooth low power, which can improve the stability and use of the connection. The battery consumption rate of both sides is even and the power consumption of operation is reduced. In other words, if used normally, there will not be a big gap in the remaining power of the left and right earphones of the current TWS earphones.
Why is there a gap of more than 15~20% in remaining power between the left and right earphones of TWS earphones?
Is there a gap of more than 15~20% in remaining power between the left and right earphones of TWS earphones? In addition to battery aging, there are usually two reasons:
1. Fixed one-ear call or use one ear:
The main reason for the large difference in remaining power between the left and right earphones of TWS earphones is usually due to enabling single-ear voice calls. When the user wears a single-ear AirPods first, the microphone of that ear will be activated first. If the TWS headset is used for calls, the longer the phone calls, the remaining power gap between the two ears will become larger and larger; if it is only used to listen to music or When using video, the difference in remaining power between the two ears will be very small.
In other words, if you use a TWS headset and are used to activating the microphone on one side or wearing one ear, the consumption of the headset you are used to using will be significantly faster than that of the other ear. It is recommended to go to iOS “Settings” > “Bluetooth” and click Already Connect the “i” button on the right side of the AirPods device, change the “Microphone” from “Automatically switch AirPods” to the option with the lowest power consumption, “Always AirPod Left” or “Always AirPod Right”, or wear headphones. When wearing the earphones with lower power consumption first, you can reduce the remaining power gap between your ears.
2. Enable single-ear noise reduction function:
AirPods Pro and AirPods Max support single-ear noise reduction mode. If you set to use single-ear noise reduction mode, and you are used to wearing one ear, it is easy to have a large gap in the remaining power of the left and right earphones.
After all, if you want to avoid a large gap in the remaining power of the left and right earphones of your TWS Bluetooth earphones, just develop the habit of wearing the left and right earphones first in turn!
