Abstract: In some examples, an electronic device includes a display panel, voltage circuitry to provide a voltage output to the display panel, and a controller. In some examples, the controller sets the voltage output of the voltage circuitry to a first voltage. In some examples, the controller obtains a first display panel power measurement at the voltage output. In some examples, the controller compares the first display panel power measurement with a second display panel power measurement. In some examples, the controller changes the voltage output to a second voltage based on the comparison.

Abstract: Apparatus, systems, articles of manufacture, and methods to provide battery cell rebalancing are disclosed. An example apparatus includes a first battery cell having a first size. The apparatus further includes a second battery cell having a second size different than the first size. The apparatus further includes a first variable resistor couplable to the first battery cell. The apparatus further includes a second variable resistor couplable to the second battery cell. The apparatus further includes a sensor to determine a first internal resistance of the first battery cell, and a second internal resistance of the second battery cell. The apparatus further includes an integrated circuit to adjust a first resistance of the first variable resistor and a second resistance of the second variable resistor based on the first internal resistance and the second internal resistance.
