Android TVs and devices like the Chromecast with Google TV use Bluetooth LE remotes so that you can speak commands to your big screen — but the downside is that these use more power than traditional IR remotes or even RF-based controllers like the forsaken Logitech Harmony series, so you end up having to swap out batteries way more frequently than you did in the pre-smart TV days. Thankfully, one company has just made an exciting announcement on this front, tagged with the bold claim that you may never have to charge a remote or change its batteries again.
