10 Laptops with the Longest Battery Life
Apple MacBook Pro with Retina Display
Apple provided several impressive hardware tweaks on the latest MacBook Pro. The most noticable is the 2880 x 1800-pixel Retina Display, which tallies up to more than 5 million pixels on a 15-inch panel.
What kind of battery can power a screen like that for 8 hours? Apple ditched the mechanical drive in older MacBook Pro's in favor of flash memory, then used the extra space to shoehorn in a larger 95-watt hour battery (up from 77.5-watt hours in the previous model). The result? A long-lasting system with enough juice to power the best 15-inch display we’ve ever seen for 8 hours and 2 minutes.
