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.

    The heat and noise problem crops up when the laptop becomes smaller. 18.4" laptops should never have heat issues, unless the heatsinks are clogged with dust, because there is a lot more room to work with. 15.6" and below tends to have some problems, especially when the manufacturer skimps on costs.

    This isn't a Lenovo, so it cools fine.

    amazing what happens when laptops arnt trying to be thin

    When do we see LG G4 review? Sorry to change topic. Its been a while.

    There seems to be a general lack of reviews on that phone. ARS hasn't published one either, only a preview. It's a decent phone and the camera should call attention to it. Then again maybe the S6 overshadowed it with its awesome camera.

    Josh is working on it. You can ask him direct on Twitter (@JoshuaHo96); it's one of a few devices he's testing concurrently.

    Thank you.

    If I was interested in this type of machine and had the money, I would buy it for sure. The thing that kills me though is the boot drive as two SSDs in raid. Just throw in a 256GB SSD and be done with it. Well probably a 512GB for the money.

    I agre just use a 256gb or 512gb ssd, raiding is pointless and can invite more problems

    Reminds me of the old 286 laptops I saw some many years ago: http://images56.fotki.com/v124/photos/1/1223041/54...

    Fun aside, that's a seriously cool laptop.
