Abstract: A scheme to initiate fast charging of a battery based on inference, situation, and/or need. The scheme uses a situational fast charging algorithm that detects user's situation and judges if fast battery charging is needed and enables fast charging. Once the need for fast charging need is detected, there are at least two options to follow. In the first option, when a charger cannot provide enough power to support both system and battery fast charging, the system turns down system power (e.g., reduces display brightness) and starts fast charging with available charger power to a sufficient charge level. In the second option, when a charger can provide enough power to support both system and battery fast charging, the system starts fast charging to a sufficient charge level.
