Disclosed are a method for reducing device power consumption and an electronic device. A master device establishes a wireless connection to a slave device, and then determines whether the slave device is a human interface device. If the slave device is the human interface device, the master device determines whether a preferred connection parameter of the slave device is obtained, where the preferred connection parameter includes a slave latency, and the slave latency includes a quantity of connection events the slave device skips before responding to a data packet sent by the master device when the slave device has no data to send to the master device. If the preferred connection parameter is obtained, the master device determines whether the slave latency is 0 or is less than a first threshold, and, if so, the master device initiates parameter update to the slave device.

Operation panel for the disabled

A solid-state battery cell, such as a lithium-ion cell, is assembled with a solid electrolyte layer member positioned between co-extensive surface layers of an anode active layer member and a cathode active material layer member. At least one of the engaging surfaces of the solid electrolyte layer is not flat. It is formed with a topographical pattern comprising recesses in a flat surface, or a surface of projections and recesses, and placed against a compatibly-shaped, mating surface of the anode layer and/or the cathode layer. The re-shaping of the surface(s) of the solid electrolyte layer and adjoining electrode layer(s) is to significantly increase the effective contact area with the facing layer of electrode material and improve the conduction of ions across the interface. A thin film of interlayer material may be placed between the surfaces of the facing cell members with the specially shaped adjacent faces.
