My Gen 2 (left) and Gen 1 (right) Ray-Ban Meta glasses (Image credit: Michael Hicks / Android Central)But these extra sessions, enhanced by better battery life, also give me more opportunities to notice these smart glasses' pain points. (Image credit: Michael Hicks / Android Central)Using them indoors at a lower volume, with Meta AI commands turned off to conserve power, the Ray-Ban Meta Gen 2s were at 69% after two hours — very efficient! Overall, the Ray-Ban Meta Gen 2 battery boost makes me much more likely to wear them for an outing or work event, knowing they won't become a pointless face-weight after a couple of hours. Meta has also promised that the Ray-Ban Gen 2s will be able to shoot in 1200p resolution at 60 FPS, but the option isn't available yet. Aside from battery life, the Ray-Ban Meta Gen 2s don't feel that different today.
