Sony patents charging system that learns your battery satisfaction
Sony describes an electronic device that tracks how satisfied you are with your battery level over time. It uses this data to calculate a specific charging voltage that keeps the battery at a level where you are unlikely to be unhappy.
In the filing’s own words
An electronic device includes: a battery; an acquisition unit that acquires, at each predetermined timing, satisfaction level information in which a residual capacity of the battery and a user satisfaction level with the residual capacity are associated with each other; and a charging unit that charges the battery with a charging voltage calculated as a voltage for charging the battery until the battery has a residual capacity that makes it difficult for a subsequent user satisfaction level to fall below a specific satisfaction level based on of a plurality of the pieces of satisfaction level information acquired and accumulated by the acquisition unit.
What exactly they claim (claim 1)
1. An electronic device comprising: a battery; an acquisition unit that acquires, at each predetermined timing, satisfaction level information in which a residual capacity of the battery and a user satisfaction level with the residual capacity are associated with each other; and a charging unit that charges the battery with a charging voltage calculated as a voltage for charging the battery until the battery has a residual capacity that makes it difficult for a subsequent user satisfaction level to fall below a specific satisfaction level based on of a plurality of the pieces of satisfaction level information acquired and accumulated by the acquisition unit.
