Abstract: An electronic device according to an embodiment may comprise a touch input unit, a first PMIC, a first switching circuit, and a battery controller. The battery controller may be configured to control the first switching circuit such that power is supplied from the battery to the touch input unit and no power is supplied from the battery to the first PMIC. The battery controller may be configured to, while power is supplied from the battery to the touch input unit and no power is supplied from the battery to the first PMIC, obtain an input through the touch input unit. The battery controller may be configured to control, based on obtaining the input, the first switching circuit such that power is supplied from the battery to the first PMIC.

Abstract: Disclosed are a method for controlling an operation of a battery on the basis of the state thereof, and an electronic device for supporting the same. The electronic device includes: a battery connector including multiple terminals; a battery detection circuit configured to detect whether a battery is connected to the battery connector; a short-circuit detection circuit configured to detect whether a battery identification (ID) terminal among the multiple terminals is short to a ground, based at least partly on a level of a voltage measured at the battery ID terminal and a predetermined voltage level; and a processor, wherein the processor may be configured to: acquire, from the battery detection circuit, a first signal related to whether the battery is connected to the battery connector; determine whether the battery is connected to the battery connector, based at least partly on the first signal; acquire, from the short-circuit detection circuit, a second signal related to whether the battery ID terminal is short-circuited to the ground; based at least in part on the first and second signals, determining whether: the battery is not connected; the battery is properly connected; or the battery is improperly connected; and control an operation of the battery based at least partly on determining whether the battery is not connected, the battery is properly connected, or the battery is improperly connected.
