Finally, charging out of thin air: OPPO showed their counterpart AirTag without a battery, which does not need charging.

Zero-Power Tag uses radio signals from cell towers, Wi-Fi and Bluetooth as power sources. Outwardly, it looks like a card, but in the future they promise to make a version in the format of an adhesive sticker.

Gadgets that do not need to be charged are the future in which you want to live.
