Battery Life

The P35X comes with a 75 Wh battery, which is fairly large by today’s standards. However there is a lot of performance under the keyboard, so battery life is always going to be the trade-off on a system like this. I think people that buy these systems generally expect that they will likely need to be plugged in for most tasks, but if you ever do need some mobility, it should be there.

To test battery life, we have two tests. The first is just a browsing test, and the heavier test ramps up the number of pages loaded, adds a movie, and has a 1 MB/s file download running for the duration. As always, we standardize our battery life tests with a display brightness of 200 nits so as not to penalize devices like the P35X which have a very bright display.

Battery Life 2013 - Light

The P35X is not going to set any records for battery life, but for a gaming system, almost five hours is fairly respectable. It is almost an hour behind the Razer Blade in this test despite the larger battery in the P35X, but it does well compared to the other gaming systems in our database.

Battery Life 2013 - Heavy

Once again the P35X falls victim to the impressive battery life of the Razer Blade, but it does hold its own when compared to the rest of the gaming notebook competition. While I would not go so far as to say the P35X has good battery life, for what it is, it is reasonable. But clearly Razer has put more work into a more efficient platform overall. We can check that out by removing the battery size from the equation in our normalized graphs.

Battery Life 2013 - Heavy Normalized

The normalized graphs show the extent of Razer’s power optimizations, because even with a higher resolution display and smaller battery, it has better battery life than the other gaming systems. But putting that one device aside, the P35X does well against the other competition. They could do better though, and this is one of the things where having multiple drives in RAID can really hurt.

Charge Time

The other aspect to mobility is charge time. Gigabyte includes a rather large 180 watt power adapter, but of course much of that is to power the system when it is operating at maximum. Although more of the adapter could be routed to the battery, there needs to be enough available to keep the device running at maximum power.

Battery Charge Time

At 170 minutes, the P35X is certainly not the fastest device to charge, but considering the larger than average battery it is not too bad.

95% charge takes about two hours, and the last 5% takes almost another full hour. If you were on the go, 50% charge is less than an hour, which is not too bad.

Overall, the P35X can be a mobile device, but as compared to other mobile devices of 2015, it is far from ideal. For these types of systems, I think the target market really is looking for portable rather than mobile, and the P35X is more portable than most gaming systems around. It does like to stay close to an electrical outlet, but for gaming, that is almost a necessity anyway despite the efforts to reduce the power consumption of GPUs.

Wi-Fi

Gigabyte has opted for the Intel Dual Band Wireless-AC 7260 wireless adapter, which is very familiar at this point. It offers a maximum connection speed of 866 Mbps from its 2x2:2 802.11ac capabilities. It has been a strong performer in the past, and while not the outright fastest 802.11ac adapter around, it still offers good performance.

WiFi Performance - TCP

400 Mbps seems to be about the average for this adapter, and the Gigabyte hits that. Speeds are good, and while some devices are faster, there is little to complain about here.

    That's exactly what I have right now, with an mITX RVZ01 and Surface Pro, but I would much rather have something lighter and doesn't require a separate monitor.

    The alternatives are gaming AIO or something like an Asus GR8 + monitor.

    From the battery life I am not sure... does it support/use Optimus to turn off the nVidia GPU when running non-gaming applications? I have a laptop with this and its great to optimize power. If it is pulling out 5 hours with the GPU enabled, color me impressed!
  • Brett Howse - Thursday, April 23, 2015 - link

    Yes it does use Optimus.

    Thanks - that is great to limit heat, fans, power usage while off the grid. Good review!

    Optimus has allowed top end gaming notebooks to get 4+ hours for a few years now, since it was implemented with some GTX 680M's. There was hate on it early on but I've had absolutely zero issues with mine for the last two years. I've had to manually select 'open with Nvidia processor' maybe, twice ever?

    Some of old MMORPG games (developed long ago) are terrible with Optimus/enduro. And I never use those as I need linux on my machines (which has terrible driver support to begin with, even without optimus)

    Wow...a gaming laptop an adult could dare to be seen with! Well done Gigabyte! At least one company recognises that not everyone is into aliens and dragons.

    Just go easy with the case stickers okay!

    Clevo has been making laptops with the fastest of fast components in a business looking notebook shell since forever.

    Continuing the stupid trend of notebook GPU parts inexplicably having twice the video memory, except much lower speed, of desktop parts for absolutely no reason.
  • meacupla - Thursday, April 23, 2015 - link

    I'm pretty sure the lower speed has always been like that for mobile parts, so I would hazard a guess and say it has something to do with power consumption and heat output.
    Probably using ULV chips.
