* mode, reducing the power consumption by 10 times or more.
* </p>
* <p>
* <b>Non-wake-up sensors</b> <p>
* Non-wake-up sensors are sensors that do not wake the AP out of suspend to report data. While
* the AP is in suspend mode, the sensors continue to function and generate events, which are
* put in a hardware FIFO. The events in the FIFO are delivered to the application when the AP
* wakes up. If the FIFO was too small to store all events generated while the AP was in
* suspend mode, the older events are lost: the oldest data is dropped to accommodate the newer
* data. In the extreme case where the FIFO is non-existent {@code maxFifoEventCount() == 0},
* all events generated while the AP was in suspend mode are lost. Applications using
* non-wake-up sensors should usually:
* <ul>
* <li>Either unregister from the sensors when they do not need them, usually in the activity’s
* {@code onPause} method. This is the most common case.
* <li>Or realize that the sensors are consuming some power while the AP is in suspend mode and
* that even then, some events might be lost.
* </ul>
* </p>
* <p>
* <b>Wake-up sensors</b> <p>
* In opposition to non-wake-up sensors, wake-up sensors ensure that their data is delivered
* independently of the state of the AP. While the AP is awake, the wake-up sensors behave
* like non-wake-up-sensors. When the AP is asleep, wake-up sensors wake up the AP to deliver
* events. That is, the AP will wake up and the sensor will deliver the events before the
* maximum reporting latency is elapsed or the hardware FIFO gets full. See {@link
* SensorManager#registerListener(SensorEventListener, Sensor, int, int)} for more details.
