Samsung patents flexible phone that adjusts battery time display when folded

Patent drawing
Patent drawing from the official filing.

This filing describes a device with a flexible screen that changes size when the housing moves. The processor calculates how long the battery will last based on the current screen size and updates the battery indicator accordingly.

Why it mattersIt improves the accuracy of battery life estimates for foldable devices by accounting for the power used by different screen sizes.

In the filing’s own words

Disclosed are an electronic device including a flexible display, and an operation method thereof. The electronic device may include a battery for power supply, a display unit, and at least one processor. The display unit may include at least one flexible display. As a state of the electronic device switches from a first state to a second state, a screen display area among a display area of the display unit may change from a first area to a second area. In the first state, a first indicator relating to a battery residual capacity identified according to the size of the first area may be displayed through the first area. In the second state, a second indicator relating to a battery residual capacity identified according to the size of the second area may be displayed through the second area.

What exactly they claim (claim 1)

1. An electronic device comprising: a housing comprising a first housing part and a second housing part configured to move with respect to the first housing part; a battery configured to supply power to the electronic device; a display unit comprising at least one flexible display, wherein, as a state of the electronic device switches from a first state to a second state, a size of a display area of the at least one flexible display which is exposed outside the housing changes from a first size to a second size; and at least one processor connected to the battery and the display unit, wherein the at least one processor is configured to: display a first indicator relating to a first usable time identified based on a residual capacity of the battery and the first size, on the display unit in the first state, detect a change of the state of the electronic device from the first state to the second state, and display a second indicator relating to a second usable time identified based on the residual capacity of the battery and the second size, on the display unit in the second state.
