Instructions on Using Bluetooth Decoding Ear Lever BTR3/BTR3K/BTR5 as Small Tail

most of the current mobile phones have limited battery life. If the decoder uses the phone's electricity again, it will greatly reduce the phone's usage time.
Feiao Bluetooth Decoding Ear BTR3/BTR3K/BTR5 (hereinafter referred to as decoder) because it supports USB decoding and has its own battery, some users will use it as a mobile phone decoder (small tail).
How to make reasonable use of the battery setting function of the decoder to prolong the battery life of the mobile phone? Careful users will find that there is a charging switch setting in the FiiO Control APP applicable to the decoder. When these products are used for decoding the mobile phone, turning off the charging switch in the APP will greatly save the power of the mobile phone.
But after using it for a period of time, when the decoder consumes too much power and starts to remind low power, the decoder will automatically turn on the external charging switch to replenish its power.
In order to let more users know more about the charging switch function of the decoder, here are some explanations for the problems that users ask more questions:

1. Can it be used as a mobile phone decoder only by turning off the charging switch?
RE: Some mobile phones have an output current protection mechanism. If the decoder is equipped with Android mobile phone decoding, according to our test, most of them can be used normally regardless of whether the charging switch is turned off or not.
If you use a third-party lightning line with Apple mobile phone decoding, because the output current of the Apple mobile phone is limited, it is recommended to turn off the decoder charging switch, otherwise the decoding function may not be used.

2. Does turning off the charging switch not consume the power of the mobile phone?
RE: Yes, the decoder will not consume mobile phone power at this time

3. Automatically turn on the charging function after the decoder is low-power reminder, will it affect the connection and decoding?
RE: If the 3.1 decoder is equipped with an Apple phone and uses a third-party lightning line, due to the current protection mechanism of the Apple phone, there may be situations where decoding and decoding are intermittent
If 3.2 decoders are equipped with Android phones, most of them will not affect connection and decoding.

4. If charging is turned on, will the decoder charge to the 100%?
RE: If the phone or charger has enough power, the decoder can be charged to the 100%.
If there is not enough power, the low-power reminder will prevail. If the power exceeds the low-power reminder, the charging switch will be automatically turned on and will not be automatically turned off;

5. Do you have to manually turn off the charging switch after each charging?
RE: At present, there is no "charging memory" option in APP. If the low power reminder point is exceeded after each decoder is charged, the charging switch will be automatically turned on. If it is to continue to be used for mobile phone decoding, it is recommended to turn off charging again to save mobile phone power. (In the future, we will evaluate the addition of charging switch memory options in the APP to facilitate users who often use mobile phone decoding)
