Please make sure to charge the battery full. If the battery is fully charged then the charge LED turns off and the charging status displays "ready".
You'll need a charger with at least 1500mA of supply current capacity in order to charge the unit while it's in use. You can check the currently detected charger current limit at the "USB current limit" field at the openSPOT4 info section on the Status page.
If you use the device turned on while charging and the charger supply current capacity is below 1500mA then the battery may deplete.
The length of the discharge time is affected by a lot of things. The battery will discharge faster if:
- The device is transmitting or receiving
- There's traffic on the connected Wi-Fi network (even if the traffic is not to/from the openSPOT4)
- Wi-Fi signal quality
- Cross mode is used
- Web interface is opened
Note that the battery charge percentage level is a rough estimate and it is normal that the percentage is different when charging or discharging.
