Fully charged normal standby time 2-4 days, when there is a phone normal use is 1-3 days, the phone will be relatively shorter.
2. Choose the right charger. Generally, Bluetooth headsets have a dedicated charger, if there is no dedicated charger, you can find the charging interface (some are thin and round holes, some are MiniUSB universal interface) the same, and rated output power of the same charger to use.
3. When charging, you should plug in all the plugs, not only more than half of them, so that the machine will be damaged for a long time. When inserting and removing the charging plug, it should be light, otherwise it will cause the plug to loose over a long time.

5. When the charge is on, the red indicator lights up, indicating that it is being charged. If the charging is complete, the indicator will turn blue or green, and the charger can be removed.
