MacBook Pro Battery Life In 2011 Vs 2026: How Much Has It Really Improved In 15 Years?
Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
MacBook Pro battery life has improved more than fourfold over the past 15 years, according to Engadget's comparison of the 2011 15-inch MacBook Pro and the 2026 16-inch MacBook Pro with M5 Max. A 2011 video rundown test by Nilay Patel showed seven hours of battery life, while Engadget's M5 Max review recorded 30 hours and 46 minutes. The gain came despite the battery growing only about 30%, from 77.5 watt-hours to 99.6 watt-hours, meaning nearly all the improvement stems from hardware efficiency rather than battery capacity. Charging speed has also advanced, with the standard power adapter rising from 85W to 140W. The comparison highlights how Apple's silicon transition has driven efficiency gains across its laptop lineup.
