Abstract: An example apparatus for powering a mobile device display includes a first voltage regulator electronically to be electronically coupled to a display backlight and to a power rail. The power rail is coupled to a power source to provide a first voltage within a first range of voltages. The first voltage regulator is to provide a second voltage within a second range of voltages to the display backlight. The apparatus also includes a second voltage regulator to be electronically coupled to display electronics of the mobile device display and the power rail. The second voltage regulator is to provide a third voltage within a third range of voltages to the display electronics. The first range of voltages, the second range of voltages, and the third range of voltages, are different voltages.

Abstract: Because a rechargeable battery has an increased number of uses (e.g., cycles), the battery's internal impedance can increase and the efficiency of the battery can become degraded. This internal resistance can cause cutoff voltage thresholds and cutoff current thresholds to prematurely stop a phase of battery charging, as these cutoff values can be based on low-cycle count batteries. New cutoff values can, instead, be based on battery impedance. Use of an adjusted cutoff current threshold during a constant voltage cycle can increase the capacity of high-cycle count batteries. Use of an adjusted cutoff voltage threshold in step charging can increase the charging speed of high-cycle count batteries. These increases in efficiency by using adjusted cutoff values can increase as the battery is further high-cycle count, in comparison with low-cycle count cutoff values used with high-cycle count batteries.

Abstract: A method and apparatus for adjusting the charge for a battery under a power sharing arrangement is disclosed. In one embodiment, the method comprises determining if power output capacity of an alternating current (AC) adapter is less than or greater than a system power requirement for a system that receives power from the AC adapter and a battery, determining a charge current for charging the battery from the AC adapter, based on a voltage range of the battery, the current charge being less than excess current available from the AC adapter in view of determining that the power output capacity of the AC adapter is greater than the system power requirement, and controlling a battery charger to charge the battery with the charge current by specifying the charge current to the battery charger if the power output capacity of the AC adapter is greater than the system power requirement.

Abstract: In embodiments, an apparatus may include a battery life monitor. The battery life monitor may, in some embodiments, receive a battery level indicator indicative of a current charge level of a battery that is coupled with the apparatus and a first temperature that may indicate a temperature of a current location of the apparatus. The battery life monitor may also receive one or more additional temperatures that indicate respective temperatures of one or more locations in which the apparatus is likely to be operated prior to discharge of the current charge level of the battery. Based at least in part on the current charge level, the first temperature indicator, and the one or more additional temperatures, the battery life monitor may calculate one or more battery life estimates that correspond with the one or more locations. Other embodiments may be described and/or claimed.
