![]() A big part of evaluating laptops is battery life. Since the tests take so long, our reviews of the new MacBook, 13-inch MacBook Air, and 13-inch Retina MacBook Pro posted without hard data for. QA Rechargeable Battery MacBook Pro: Realistically this battery will last around 3 hours as long as there is not heavy usage of the CPU or GPU. So as long as you are doing basic things like e-mail, web surfing, etc you should get decent life out of it. ![]() SEE ALSO: In a published last week, Slaney — who develops a macOS battery life indicator app called Battery Guru — says that the power efficiency on the 15-inch, 2016 MacBook Pro is excellent, far better than on previous MacBook Pros. Here's the trick, however: Apple managed to significantly decrease the power draw of the new MacBook Pro under low power usage conditions — basically when the computer is idle. So if you're just reading an article on a website, with nothing going on in the background, you can expect the battery to last up to 18 hours, according to Slaney's calculations. 'I’m impressed that the new MBP will happily sit at a 500 mA power draw for long stretches of time. This is a greater improvement than I would have thought possible,' wrote Slaney. What about the professionals and the power users? Under heavy load, however, the power draw is similar to the earlier generation, but the new MacBook Pro has a 25% smaller battery, so when you push it hard, you won't get great results. This is likely why some pro users are dissatisfied with the new MacBook Pro's battery life. They do a lot of intensive tasks, and in that scenario, Apple's optimizations don't help much. What's needed is, simply put, a bigger battery. Many professional users don't like the direction Apple has headed, but Slaney argues it's not that big of a deal. 'Personally I wish that Apple would make huge laptops which weigh 10 pounds with dual graphics cards in them,' he told Mashable in an email. 'However, given the angle that they have taken (.), I think the concerns about battery life are overblown.' Slaney points out that his results are observational and aren't based on rigorous testing. But they do explain the discrepancies we've seen in the new MacBook Pro's battery life, depending on who's using it. So if you own a 2016 MacBook Pro or are considering buying it, what should you do? One thing you can do is monitor your battery drain — Slaney's will do the trick, but there are that do something similar — and see if the apps you use daily are big battery hogs. If they are, and there's just no replacing them, the new MacBook Pro likely won't make you happy. If you don't mind checking your Chrome tabs for power hogs and killing them every once in a while, the new MacBook Pro's battery might last well beyond 10 hours. On the other hand, if you typically don't use very CPU-intensive apps, and you don't mind checking your Chrome tabs (a frequent battery drain culprit) for power hogs and killing them every once in a while, the new MacBook Pro's battery might last well beyond Apple's advertised. Here's another thought. According to Slaney, macOS Sierra already supports external batteries; if Apple were to release one (third party manufacturers, but none of them are certified to work with the Pro, only the 12-inch MacBook), you could just plug it into one of those USB-C ports on the new MacBook Pros and get a big battery life boost. Top 5 vpn free for mac 2017. True, that kills a lot of the joy in having a super-thin laptop, but if you don't mind the extra bulk, it could be a good compromise. Slaney agrees. 'I really think that very soon there’s going to be first party or third-party absolutely fantastic power banks for these things, by virtue of the USB-C port.' And when USB-C power banks become ubiquitous, Slaney claims, the internal battery life on a portable life will become 'less important.' Hi, I have had my new 13' MacBook Pro since one week and I am completely unsatisfied with battery life. I am not even remotely getting close to the advertised 10 hours at 75% brightness. Right now, I have set my screen to 50% brightness while I am typing this in the browser. The machine basically is at idle with the TouchBar and keyboard illuminated just a bit (sitting in a dimly lit room). My battery is charged 95% and I am getting 5:00 hours remaining charge (so basically just 50% of advertised at even lower brightness). I know that battery measurements usually take place under 'ideal' conditions. However, this just seems to be a ridiculous mismatch between advertisement and reality.
