An electronic device comprising:

• a first housing;
• a second housing movable with respect to the first housing;
• a rollable display at least partially fixed to the second housing and configured to be inserted into an inside of the first housing in a slide-in state of the second housing or drawn out from the inside of the first housing in a slide-out state of the second housing;
• a wireless charging integrated circuit (“IC”) in the first housing or the second housing and configured to be capable of receiving power from an outside;
• a battery in the first housing or the second housing and configured to be charged with power received from the outside through the wireless charging IC;
• and
• at least one processor is configured to:
• based on the slide-in state or the slide-out state of the second housing with respect to the first housing, determine an amount of a current to be received from the outside through the wireless charging IC or an amount of a current for charging the battery, wherein the current to be received from the outside through the wireless charging IC is different from the current for charging the battery;
• and
• transmit a signal related to the current to be received from the outside through the wireless charging IC or the current for charging the battery to the wireless charging IC.
