Battery level drops too quickly
The drop-in battery level is not necessarily linear across time. The battery
level may also fluctuate when a sensor is connected or disconnected.
However, the operating duration should still be more than 4 hours on a
single full charge under normal use (i.e. with screen dimming and no USB
connection).
If the device is left or operated for prolonged
period under an ambient temperature of below 0
degree Celsius, the total operating duration may
be reduced.
If the battery is less than 6 months old and the
normal operating duration is significantly
shorter than 4 hours at room temperature, then
pre-mature battery damage is indicated.
Abnormal power
consumption
The sensor draws majority of its power during
operation. Verify that there is no abnormal
power consumption caused by a faulty sensor.
