Meta's new Ray-Ban smart glasses have twice the battery life

"Let's dig in on battery, which is better on a few fronts. You can use the new Ray-Bans for up to eight hours on a single charge, which is twice the four-hour battery life of the previous generation. The charging case can charge the glasses to 50 percent in 20 minutes - a slight improvement over the 22 minutes to 50 percent for the first generation. The case for the Gen 2 glasses offers an additional 48 hours of battery life, up from 32 hours."

"As for the camera, you'll be able to record 3K at 30fps, 1440p at 30fps, and 1200p at 60fps, all for up to three minutes. Later this fall, Meta will also add the ability to capture hyperlapse and slow-motion videos - a feature coming to all of its AI glasses. Meta is adding a cool audio-focused feature called "conversation focus" down the line, too, which will use the speakers on the glasses to boost the voice of a person you're talking with."

"I tried the Gen 2 glasses at Meta's Connect event, and there's not much to say about them at first blush - they're a solid upgrade on paper, but they're ultimately still Meta Ray-Ban glasses, so if you've used the first generation before, you pretty much get the idea. You'll be able to buy them in Wayfarer, Skyler, and Headliner styles. The first-generation glasses will still be available, too, starting at $299."

The Ray-Ban Meta Gen 2 offers up to eight hours of use per charge, doubling the previous generation's four-hour battery life. The charging case replenishes the glasses to 50 percent in 20 minutes and provides an additional 48 hours of battery life. The glasses can record 3K at 30fps, 1440p at 30fps, and 1200p at 60fps for up to three minutes, with hyperlapse and slow-motion capture arriving later. A forthcoming audio feature called "conversation focus" will amplify a conversational partner's voice through the glasses' speakers. Live translation will expand to German and Portuguese. Models are available in Wayfarer, Skyler, and Headliner styles, starting at $379; first-generation options remain available from $299.
