The slow charging and fast power consumption of headphones is due to their smaller battery capacity, and the charging mode and usage mode are different. Under normal circumstances, the auxiliary headset needs to synchronize data from the host, so it occupies more power than the host when used; During the charging process, due to current sharing, the charging speed of the headset will be slowed down. Therefore, when using a pair of headphones, you need to pay attention to control the volume and use time, so as not to consume power quickly, while choosing a better charger and charging cable can also improve the charging speed.
When AirPods and iPhone (device) Bluetooth online transmission, only one headset will be connected, the first connected device will become the main headset, at this time the main ear will lose data to the headset and the connection, which is equivalent to AirPod headset and device connection actually only one ear in the transmission signal, that is, the real wireless Bluetooth headset's main and secondary ear transmission technology. It will cause the main earphone to be responsible for communicating with the auxiliary earphone and synchronizing the left and right sound channels, and the power consumption of the main ear will be more obvious;
