Smart rings are electronic devices, which means there are components that enable them to do what they ought to do. These components include sensors, wireless modules, and circuitries, and often these components require power to function. In short, smart rings need charging.
However, some smart rings do not need charging at all. Called passive rings or NFC rings, these types of smart rings use near-field communication technology to do their purpose.
Are they still smart, though? Technically, yes because they do things that cannot be done by regular rings. For instance, NFC rings can be used for contactless payments, keyless access, car keys, or as a remote control.

Smart rings may be small in size with a tiny power source, but their battery power can last longer than mobile phones or smartwatches. The lack of a screen is a huge factor in why it is so.
Only sensors use up a smart ring’s power, which can last up to 7 days, depending on how sophisticated they are. With basic health and fitness functionalities like sleep tracking, activity tracking, and 24/7 heart rate monitoring, smart rings can last 4 to 7 days. With more advanced uses like blood sugar monitoring, smart rings can last 3 to 4 days.
