Battery Life

Normally on a notebook review, I would consider battery life to be one of the key aspects of the experience. However the GT80 Titan is not a typical notebook. This is really a device designed to sit on a desk and be used in lieu of a desktop computer. But if you ever feel the need to pick up this 10 pound laptop and lug it to the coffee shop, I suppose we should see what kind of battery life you can expect.

The GT80 Titan lacks NVIDIA’s Optimus technology, so it can’t switch from the discrete graphics to integrated graphics on the fly. MSI has included a hardware switch to change to integrated graphics, but it does require a reboot in between. Just to see how much of a difference this makes, I ran the light test first with the GTX 980Ms active, and then again leveraging Intel’s integrated GPU.

Battery Life 2013 - Light

Our light test is light web browsing with the display set at 200 nits. The 80 Wh battery inside the GT80 Titan is really no match for the hunger of the SLI graphics cards, and with those enabled the battery life is a mere two hours and twenty minutes. However once you disable the GPUs and switch to the integrated GPU, the result is actually a pretty respectable four hours and nine minutes. Considering the size of the display and the power underneath the covers, I was actually shocked it was that high.

Battery Life 2013 - Heavy

The heavy test ramps up the amount of pages browsed, adds in a 1 MB/s file download, and a movie is played back using the Windows 8 Video app. On most devices, the light test result is often dictated by the display power, and the heavy test shifts that balance over to the CPU and I/O. However with the power hungry components in the GT80, the difference between the light and heavy tests results is less than normal with it getting just about an hour less overall. Even though it is just three hours fifteen minutes, it actually ties the Sony Vaio Haswell based Ultrabook in this test, but it does have over double the battery capacity of that much smaller notebook.

Looking at the normalized graphs, the GT80 shows just how much energy is needed to power the CPU and large display. Once you turn on the GPUs though, the power usage really gets ugly and the light result with the GPUs enabled is one of the worst we have seen. Even though NVIDIA has been improving power efficiency and idle draw of their GPUs, they still are not in the same league as the 14nm Intel GPU when discussing minimum power draw.

Charge Time

In order to provide enough power for the two GPUs plus the quad-core CPU, MSI ships the GT80 Titan with a massive 330 watt A/C adapter. This power brick alone weighs more than some notebooks, but it is necessary to keep up with the insane power requirements of this notebook. With that much power available, MSI could have chosen to reduce the charge time pretty substantially.

Battery Charge Time

Looking at the time though, the GT80 charges in roughly the same time as most notebooks. Even though they could have provided more power to the battery, this may have required beefed up circuitry, and even if that is there, it can be hard on the battery due to the heat generated. MSI was fairly conservative here but the end result is a fine 2.5 hours.

    Yeah.. very different machine. USG.. What I meant by my comment is you see a laptop and you like many things about it but you wish there were enhanced downgrade (..or for some upgrade) features to tailor it into something you'd buy.

    I personally believe that these companies leave a shit-ton of money on the table by going the route they go... as most of us are not really in the market for a new item but could be enticed if it was more customizable.

    uhhhh.... Clevo? Whitebook concept? They have been doing that for decades. Resellers do the customising. The last one I ordered was without RAM, O/S, HDD, Wifi card. Most often the comment from people who want a custom quote is "gee it's expensive" - duh, it's non-Chinese-peasant labour intensive.

    What are you on about? That's a totally different machine lol, try their GE62 if you want a portable device. You can't really fit a mechanical keyboard in a 15" chassis so it may as well be 18".

    4.5kg. ugh.
  • meacupla - Friday, June 26, 2015 - link

    That's not terrible, considering that a separate TKL mechanical keyboard weighs around 1.1kg.

    I don't understand why you even bother complaining about the weight of something that has an 18.4" screen. It's not something you'd want to tote around everyday anyways. Clearly, if you wanted a light weight laptop, you would be looking at sub 1.2kg, 10" to 13" ultrabooks or convertibles anyways.

    It'd be best not to think of this as a laptop. It's more like a LANbox with its own power supply and flip up display. :)

    exactly I use mt m18x as a lan box and it is the most portable pc of all my friends and is faster than most too with 4.2ghz i7-2960xm and SLI GTX 780m.
  • Notmyusualid - Saturday, June 27, 2015 - link

    And, as I'm sure you will know, those 2960XMs have been seen doing 5GHz too...

    Yeah well, but keyboards like that have a heavy base on purpose: To make it not move on the desk.
    Have you ever checked those on the inside (sometimes is obvious on the outside). They use a thick metal plate.
