Why are the usage times and the battery power of the left and right earbuds of the Redmi Buds 6 Play inconsistent?

By default, the earbuds taken out first from the charging case are the primary ear, and the earbuds taken out later are the secondary ear. When the primary ear is responsible for the same function, it is also responsible for transmitting data to the secondary ear and connecting to the phone, so the power consumption will be relatively high compared to the primary ear, and the usage time will be relatively short.
In addition, if you are accustomed to wearing one earbud and charging the other earbud in the case, it is easy to cause the left and right ear battery levels to be out of sync when both earbuds are used. It is recommended to wear the left and right earbuds in the same way to confirm the difference in battery endurance between the left and right earbuds.
