If your Ring Video Doorbell 2 is hardwired to an existing doorbell, that will keep it charged. If your Ring Video Doorbell 2 is not hardwired, the battery will need to be periodically recharged.
Ring says the battery should last between 6 to 12 months on a single charge, but it still depends on how much activity your video doorbell is recording.
Check your doorbell transformer's voltage
Your wired Ring doorbell might not be working because it doesn't have enough voltage. Your device requires between 8 and 24 volts to work properly. You'll want to stay toward the high end of that range to make sure the battery can fully charge when your device is hardwired.
It'll work off the removable and rechargeable battery. Or you can install it using your existing doorbell wiring, assuming your transformer provides between 8 and 24 VAC. (If you have a newer home, you're likely fine.
Rechargeable lithium-ion batteries commonly perform poorly in cold conditions. If you're having issues with your Ring doorbell not charging, it may be due to the outdoor temperature.

However, the doorbell still needs the battery to operate even if you hard-wire it using the doorbell cables already present in your home or an A/C converter. Any hard-wired power source will recharge the battery in place of the doorbell itself for all Ring doorbell models that have batteries.
In your case, you should recharge your battery back up with the USB cable. Then monitor to see if it drains again. Also check to see if your Doorbell was operating only on battery power and has drained down (not displaying “Hardwired” or missing the “Lightening Bolt” in the Battery icon).
Unplug them for about 10 seconds, then plug them back in again. Confirm that your Ring device has power. If it is hardwired into your doorbell system (instead of battery-operated), you may have a doorbell circuit breaker in your breaker panel. Flipping the switch back to the on position can fix the problem.
Installation/Wiring: The Ring video doorbell model is wireless, while the Ring Pro model must be hardwired. Each method has its advantages. Wireless equipment is handy and easy to install, while hardwired equipment tends to be more reliable and you won't need to worry about changing batteries.
