Battery Life and Charge Time

Battery life takes a back seat in gaming laptops, especially since the nature of G-SYNC requires that the dGPU has to be directly connected to the display, and therefore Optimus is unavailableUpdate: Some readers have let me know that Acer offers an option in the BIOS or in their PredatorSense to choose between having G-SYNC or Optimus, meaning they have a MUX installed allowing the GPU to be directly connected to the display, or through the iGPU for battery life. The Battery Tests were re-run with Optimus enabled. Running a massive GPU to do desktop tasks takes a lot of power, full stop. Acer has offered an 84 Wh battery to try to compensate, and they also offer optional Optimus which means you can get some battery life savings by disabling G-SYNC and using the Intel iGPU for light loads.

Our lightest test just cycles four web pages per minute, and isn’t very much work for a modern system. With Optimus enabled, the battery life is very reasonable for a gaming laptop system. The base power drain is still quite high, but compared to gaming systems that don't offer Optimus the Acer is far ahead.

2016 Web

Our newer web test is much more demanding of the processor, and generally results in quite a bit drop in time compared to the light test, but gaming laptops are a different beast, and the high base power draw generally masks any such changes in CPU usage. In fact, the more demanding test actually provided slightly longer runtime, and with Optimus enabled the battery life is downright reasonable.

Normalized Results

Removing the battery size from the results gives us our normalized results, where we can see the efficiency of the various platforms. The Acer Predator Triton 500 is actually a fairly efficient gaming laptop, even though it’s still not great. The industry is actually making progress here, just far slower than they are on the Ultrabook side. The Acer allows the GPU to be switched off with a multiplexer, and when Optimus is enabled the efficiency is significantly higher. The downside is it does require a reboot, and you lose G-SYNC until you re-enabled and reboot again, but if there are scenarios where the extra battery life is needed, the Acer offers the best of both worlds.

Movie Playback

Once again with Optimus enabled the battery life is reasonable here, and it's a fantastic option that Acer has to allow you to choose between Optimus and G-SYNC. The base power draw is still quite high compared to an Ultrabook, but the overall runtime is a lot better than a gaming laptop that forces the media playback to leverage the dGPU.

Tesseract

Dividing move playback time by the length of a long movie gives us our Tesseract score, and you can playback the Avengers about 1.5 times before this laptop shuts off with G-SYNC enabled, and two movies played back with Optimus enabled.

Battery Life Conclusion

Acer is one of a few manufacturers offering a multiplexer on the dGPU, allowing the end user to choose between Optimus and G-SYNC, and the results are worth it. If you are doing desktop work and need some extra battery life, the Triton 500 deilvers far more than most gaming laptops. It can't keep up with a low-powered Ultrabook here, but still easily outclasses the competition that does not offer the MUX.

Charge Time

Acer ships the Triton 500 with a 180-Watt AC Adapter with a barrel connector. For those wishing for USB-C charging, the maximum power for USB-C power distribution is 100 Watts, which is not enough for a gaming laptop, which is why they still rely on proprietary power connectors.

Battery Charge Time

You can go from zero to full charge in just over two hours with this laptop, which is pretty good considering the size of the battery. But most likely, the battery will be a mini-UPS for moments when the power goes out anyway, since this laptop is made to be plugged in most of the time.

    With all the power related limitations with mobile GPUs these days I'd love to see a nominal equivalent desktop system added to the tables as a reference baseline.

    3k laptop. I'll stick with my 17" Lenovo laptop from 3 years ago with a 980m that I got for 900. Plays everything I throw at it very well.

    You can find diamonds in the rough. I bought a Alienware 17 R5 with a "1070 OC" they call it, and can get it within 10-15% of my friends Asus G703 with an overclocked 1080. That laptop was $3500, mine was $1500 base + 1TB NVMe Evo, and 1TB SSD Evo I added to it coming out around $1800. While I dont care too much for Alienware in general, I knew this chassis could take an i9/1080 combo,so I knew it would handle an i7/1070 easily, which it does with no throttling. With laptops, its all about finding a chassis that can handle the hardware without throttling.

    Did you do an iUnlock and liquid metal the R5? I had to do it on my 17R4 but still working great after 2 years of ownership in my backpack.

    Pretty impressive amount of power for a portable device.
    Would love to see a review or 2 sprinkled in of the more middle range laptop hardware, too.

    Good looking laptop until we get to the last page and there is that big old I'm a grown man in the basement messaging a 13 year old predator logo. :p Marketing Acer, Marketing. Research it.

    This! I dont know why its so hard to find a aesthetically pleasing high end laptop! haha. The MSI GS75 Stealth is an amazing looking laptop, if only it wasn't a Max-Q design! I only wish the screen lid came on the MSI Raider with the full fledged 2080. But no, they want to stamp that with "Dragon scale" LED strips What?? Teenage looks with seriously adult prices.

    Ahh, its nice, but would like a full 2080 non Max-Q and a 17inch display. 15inch is just too small for my liking. I have owned a lot of Asus ROG laptops (get a new one every 2 years through my work as my treat to myself). 15 inch laptops even some of the better ones, have issues with throttling. That extra 2 inches of space helps with cooling in the small form factor of a laptop. The GS75 Stealth is a nice looking laptop, but I just cant get over the 30% hit from Max-Q. I would look at another G703 from Asus, but that laptop is now pushing $4k with a 2080. I had the G703 w/1080 before I sold it to a friend due to needing some money due to some unfortunate events, It was a really nice solid laptop, but was really pushing it at $3500. I just cant justify spending over 3500, that was even a stretch.
