Battery Life

By Ultrabook standards, the 47.5 Wh battery capacity in the Surface Laptop 2 is on the light side, as some of the competition can offer 60 Wh or so. But Microsoft tends to focus quite a bit on power usage instead of raw capacity, and as a result can eke out extra battery life through other means. The battery is only slightly larger than the 45 Wh in the Surface Pro 6, and it performed well in our battery rundown tests.

To test the battery life, we calibrate displays to 200 nits to make the test as even as possible, and then run through several workloads.

2013 Light

Our lightest test is our oldest, which cycles four webpages per minute. The scripting isn’t a very big task for modern processors. Despite the smaller battery, the Surface Laptop 2 lasted for over 11.5 hours, which is fantastic.

2016 Web

Battery Life 2016 - Web

Our web test involves a lot more work for the CPU, and as such the results are generally quite a bit lower than our older light test, and that is the case here again with the Surface Laptop losing over an hour of runtime compared to the light test, but it still came in well above any other laptop we’ve tested, offering over 10.5 hours of runtime.

Movie Playback

Battery Life Movie Playback

Media playback allows the CPU to offload work to fixed function hardware in the media block, which allows most of the processor to go to sleep. The Surface Laptop was able to play back a local movie file for over 15 hours, which is amazing considering the battery capacity here.

Battery Life Tesseract

Our Tesseract score puts the movie playback into a more usable number. The runtime is divided by the length of a long movie (The Avengers) to get a result in terms of how many movies you can watch in a row. The Surface Laptop 2 is ready for any movie marathon you’re after.

Normalized Results

By removing the battery capacity from the equation, we can take a look at the efficiency of each device. The Surface Laptop 2 outperforms all other laptops we’ve tested here. Microsoft has put a tremendous amount of effort in the getting power consumption in check across their lineup, and the lower display density of the Surface Laptop 2 puts it at the top of their devices, as well as the top of any laptop we’ve tested. It is a truly impressive result.

Charge Time

Microsoft ships the Surface Laptop 2 with a 44 Watt power supply, and in typical Surface fashion it offers an incredibly useful USB charging port built into the brick. The charger connects via the Surface Connect port, which is the same proprietary magnetic connector Microsoft has been using since the introduction of the Surface Pro 3. It’s a great connector, it’s easy to connect, and it offers a light on the side so you know whether or not it’s charging or not. The only thing missing is it would be nice to have the USB-C port for charging as well, which would make travel even easier.

Battery Charge Time

The Surface Laptop 2 isn’t particularity quick at charging, but it’s within a few minutes of the other Surface devices. Microsoft doesn’t seem to want to charge the battery too quickly, which may help with longevity, but thanks to the efforts they’ve put into the battery consumption, they likely don’t need to put as much weight on charging.

    If only they would release "naked" option... without cloth deck.

    I just can't make a peace with cloth hard-glued to metal body. I like the feel of metal, and it is much easier to clean and maintain. I am fully aware this is my peculiarity - I am not big fan of Dell XPS carbon fibre deck, either (demo machines in the shops look very untidy and fingerprint frenzy)...

    I don't mind cloth On Surface Pro. It can be easily replaced. I seem to have paranoia of damaging this cloth accidentally - spill or sharp object - and having to live with it for the rest of machine's life. Scratch on metal surface feels better than teared cloth. And metal does not stain as much as cloth.

    I agree, fabric is just a bad idea.

    Not really a bad idea in itself. The bad idea is its glued on so you can never fix it...

    No stain whatsoever on my keyboard deck (5 months of use), but I must admit, having this paranoia on whether my hand is clean enough to touch my notebook isn't too much fun. It's not that I often touch my previous laptops with a dirty hand, but I didn't feel the constant paranoia of it before.

    My original Surface laptop shows no signs of any staining, scratches, or anything else and I use it daily. After using it for so long, metal feels odd and uncomfortable. The slight cushion that the surface has makes it very comfortable to wrest your palms on for long periods of time.

    That USB port is a joke.
  • Lord of the Bored - Friday, March 29, 2019 - link

    Seriously. What the hell kind of computer only has ONE USB por- oh, you meant that it is a compatible port instead of needing an additional adapter to connect to anything you want to use it with.

    I wouldn't want to spend $2199 and end up with only 512GB of storage. For that price the laptop better do *everything*.

    No USB-C = No buy. If it's incredibly annoying in 2019, imagine how annoying it's going to be in 2022 assuming you keep this laptop for a few years.

    Pretty much the #1 reason I didn't opt for this, otherwise it was top of my list.
