We can determine whether the remaining battery charge level on the OnePlus smartphone should be displayed in percent so that we don't have to estimate between 1/4 or 2/3 remaining capacity.

When this function is activated, a percentage is displayed next to the battery icon in the status bar to show the exact battery charge level at all times.
