Abstract: Various embodiments provide a Bluetooth-based playback method and an electronic device. In those embodiments, a first processor copies a coding algorithm, a sound effect postprocessing program, and a Bluetooth audio transmission protocol to a second processor, transmits first to-be-decoded data to the second processor, and enters a sleep state. The second processor receives the first to-be-decoded data, performs decoding, sound effect post-processing, and coding on the first to-be-decoded data to obtain first coded data, and sends the first coded data to a Bluetooth module using a third processor. The Bluetooth module converts the first coded data into a first wireless signal, and sends the first wireless signal to an external playback device to implement audio playback. The first processor is communicatively connected to the second processor, the second processor is communicatively connected to the third processor, and the third processor is communicatively connected to the Bluetooth module.

Abstract: A heart rate detection method and an apparatus, where the method is applied to an electronic device, and the electronic device includes a heart rate sensor. The method includes detecting, by the electronic device, a current motion status of a user carrying the electronic device, determining, based on a prestored correspondence between a motion status, a startup period, and a sampling rate, a startup period and a sampling rate corresponding to the current motion status, where the startup period is a period in which the heart rate sensor is started to detect a heart rate of the user carrying the electronic device, and the sampling rate is a sampling rate of collecting heart rate data by the heart rate sensor, and starting the heart rate sensor at regular intervals based on the startup period to collect heart rate data at the sampling rate.

Abstract: A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program. It can be learnt from above that, the terminal can determine, according to a variation in light intensities, whether the terminal is blocked by clothes, and close the target program. This reduces running power consumption of the terminal and increases a standby time of the terminal.

Abstract: An information display method and an apparatus are described wherein a terminal obtains a first operation entered by a user. The terminal further obtains at least one key character based on the first operation. The terminal further determines that characteristic information associated with the key character is stored, and displays target information associated with the characteristic information. The target information is information that is in a set of information associated with the key character and that is associated with the characteristic information. The method can improve information display precision.
