There are some things that drive me nuts about my MacBook Pro 13 (mainly the battery life), but the outdoor view-ability of the screen is top-notch. And, interestingly, cranking the screen brightness doesn’t hurt battery life as much as you’d think. At minimum (one-notch) brightness with the MacBook Pro being passive, using iStat Menus, power use was a mere 1.94 watts. That’s pretty incredible and shows how dramatically the overall system scales down power usage.
On the flip side, if I crank the screen to it’s eye-searing maximum brightness – which Apple says is 500 nits – it uses up 8.11 watts. That’s a 4x increase in power consumption, yes, but 8 watts is still not a massive power drain. The screen Apple used is both bright and efficient.
Unfortunately, the scenario where I crank the screen brightness up to maximum to use it outdoors yet do nothing that uses the CPU aggressively is a rare one. Maybe if you wanted to watch a movie outdoors in the daylight? That’s not a scenario I’ve found myself in just yet.
