A system includes a processor, a charger circuit and a battery management unit (BMU). The charger circuit charges a battery. The BMU includes an intelligent boot module that can send a boot signal to the processor based on information including a battery condition and system information. The processor starts a boot sequence based on the boot signal.

An electronic device may have a power system with a battery. The device may include power management circuitry that helps distribute power from the battery to components within the device. To prevent an excessive load from being applied to the battery and the battery from dropping below a cut-off voltage, power management circuitry may control power consumption by components in the device. Power consumption models in the power management circuitry may be used to ensure that maximum allowable power consumption levels are not exceeded. To help accurately and quickly manage power consumption decisions, each component may have characteristic power consumption values that characterize the power consumption profile of the component. These characteristic power consumption values may be provided to the power management circuitry with a request for power consumption and the power management circuitry may determine maximum allowable power consumption for the component based on the characteristic power consumption values.

Electronic device with battery capability modeling

A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Direct-lit backlight units with light-emitting diodes

A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes on a printed circuit board. The backlight unit may include first, second, and third light spreading layers formed over the array of light-emitting diodes. A color conversion layer may be formed over the first, second, and third light spreading layers. First and second brightness enhancement films may be formed over the color conversion layer.
