Battery Life

On most systems, battery life is arguably one of the most important aspects, but a desktop replacement device like the MSI GT75 Titan is so large and so heavy that it’s unlikely to ever be used away from a desk. Also, these systems tend to offer high-performance components on the inside, and those generally mean high-power draw.

As such, the battery in any system like this is more or less a glorified uninterruptible power supply, unless you want to use it away from the plug for a really short time.

MSI does offer the GT75 Titan in two configurations. The base tier is a 75 Wh battery, and the top models come with a listed 90 Wh battery. We’ve got the top unit, so it should have a 90 Wh battery, although powercfg only lists the capacity at 79,344 mWh of capacity.

Update: MSI let us know that the review unit is an early model which came with the 75 Wh battery, and all new units come with the correct 90 Wh.

Battery Life – 2013 Light

Our older test has become too light for modern machines, but for now we’ve kept it due to the abundance of older devices that have data for it. Regardless, on a system like this the base power draw is so high that any light workload doesn’t really impact the results, so this is more or less the same as it would be at idle. At under three hours runtime, it’s not great.

Battery Life – 2016 Web

Our 2016 version of the test is much more demanding, which generally lowers the result quite a bit on a low-power device, but on a gaming system such as this, the base power draw masks almost any light load, so the result is almost exactly the same as the older test.

Normalized Results

Just as a note these calculations are done with the battery capacity listed at 80 Wh, rather than the 90 Wh on the spec sheet, because this system isn’t able to see the full 90 Wh. The normalized results remove the battery capacity from the equation, and show how many minutes you’ll get per Wh of battery. In this case, it’s not very good.

Digging into this a bit more, the base power draw of the system at idle was found to be between 25 and 30 Watts. That explains the poor battery life. Having a high-end six-core CPU paired with a beefy GPU that can’t be powered off is going to do this, of course.

Battery Life – Movie Playback

Amazingly the movie playback, which is generally the least demanding workload we test, was within one minute of the light battery test. So if you’re going to watch a movie on this laptop while unplugged from the wall, just be aware you’re going to get less than three hours of playback.

Battery Life Tesseract

Our Tesseract score divides the movie playback time by the length of The Avengers, to get an idea of how many movies you can watch on this system. As you can see, it’s best to finish your popcorn before the first movie is over.

Charge Time

The MSI GT75 Titan comes with not one, but two 230-Watt power supplies, which connect into a Y connector and then into the laptop. The base model comes with a single 330-Watt model, and that would likely be enough for this system unless you were overclocking, which you can, so the two power supplies make sense.

Battery Charge Time

The charge time isn’t amazing despite the huge amount of power available, but this isn’t a system that’s going to likely need to be charged quickly anyway.

    My MSI GT75 also reports the same battery capacity - "DESIGN CAPACITY 79,344 mWh."
    I wonder when they'll actually offer it with the 90Wh.

    I just got a reply back from MSI on this. Early models of the GT75 Titan came with the 75 Wh and the current ones are offered with either the 75 Wh or 90 Wh depending on model. I added an update to the battery page about this. The review unit is an early build date and as such comes with the smaller battery. However the run time difference isn't going to be much different either way. Likely less than 30 minutes extra due to the high idle power consumption.

    10 Gbps Ethernet as an option but can't even get 3x3 Wi-Fi? Consumer 4x4 wireless routers have been out for some time now, as well. [scratches head]

    There are very few 3x3 wireless NICs around. You'd likely be better off utilizing the 160 MHz channels available on the NIC that's in this laptop already.

    Which should be cheaper to buy india or abroad as i will be buying i7 8th gen, and budget is 2 lakh

    Any idea of how this fares against Ryzen 2*** series, especially the Ryzen 7 2800H, which has a similar TDP?

    Today’s fashion is not only bounded with women’s fashion and trendy clothes but also men’s fashion is increasing day by day and as well as competition in the world. <a href="http://www.celebstyleoutfits.com/mens-jackets-coll... leather jacket bomber</a>
