Battery life is one of the most-searched, and least directly comparable, specs for AI glasses. Manufacturers measure under their own conditions, and "typical use" doesn't mean the same thing across devices and test methods.
Even G2: the manufacturer claim
Even Realities states the Even G2 carries a 192mAh battery that lasts around two days under typical use. The included charging case can fully recharge the glasses roughly seven times, per the manufacturer, before it needs power itself. These figures come directly from the Even Support Center and are a manufacturer claim, not an independent measurement by AI-Eyewear.

Why "typical use" varies
An average figure hides that individual features draw very different amounts of power. Someone who wears the glasses mostly for occasional notifications will land closer to the manufacturer's figure than someone running live translation or the teleprompter for hours. Independent reviews of various smart glasses models repeatedly describe sustained display and translation use noticeably cutting runtime — but the exact magnitude differs from model to model and isn't documented with reliable figures for every device individually. We don't have an independent lab measurement for the Even G2 itself; our planned AI Eyewear Score is meant to change that once we've tested a unit ourselves.

Pick your typical usage profile. The tool maps it loosely against the manufacturer's figure and shows a range rather than false precision.
How long will the Even G2 last for you?
A rough estimate based on the manufacturer's claim — not a lab measurement.
Method: starting point is the manufacturer's claim of "around 2 days under typical use" (Even Support Center). For heavier display use we show a lower, deliberately wide range, drawn from the general pattern described in independent reviews that display use reduces runtime — not from our own measurement of the Even G2. All figures are estimates, not lab results.
What this means for buying
For most everyday scenarios — notifications, occasional translation, short teleprompter use — the Even G2 stays close to the manufacturer's figure. If you're planning long, sustained translation sessions, for example on a multi-hour trip, bring the charging case along. See the purchase page for case and pricing details, and the AI glasses database for specs on other models.
