The Siri Remote on the new fourth-generation Apple TV incorporates a rechargeable battery, and Apple promises “months” of battery life on a single charge, at least for whatever the company considers “typical use.” You shouldn’t need to charge your remote often, but if you’re curious to check how much battery life is remaining, you can do this by going into the Apple TV Settings and selecting “Bluetooth” under “Remotes and Devices.”
Your Siri Remote will be shown on this screen with a battery indicator showing how much juice is left.
Of course, you can plug the remote in at any time to charge it up — just use a Lightning cable with a USB wall charger or a port on your computer.
It will take about 9 hours to reach a full charge, but the good news is that you can also still use it while it’s charging back up.
