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.

2013 Battery Life Light

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.

    You're looking at something similar to me; only I'm not interested in the 2080 specifically as it's comically overpriced. I'd prefer a 2060 and enough thermal headroom to get it running at something close to actual desktop 2060 performance.

    nVidia really dropped a bollock this generation. After having rough performance parity between desktop and notebook with Pascal (Max-Q snake oil excluded) they quietly dropped it for Turing but kept the same naming convention. The performance disparity is egregious now, while prices have been out of control since Maxwell.

    Guess there are enough 16 to 25 year olds with $3k+ to spend on gaming laptops who love the bling. Beyond my understanding.

    I have the triton 500 and it doesn't have Optimus but there is and option to turn on Mshybrid in the BIOS and in the predator sense software settings gear wheel there is an option for dgpu only which if turned off I believe does the same thing.

    Also would never have bought the laptop at full price but managed to get the $2500 model for $2100 tax free from Best Buy.

    Hi Junz. Thanks for the tip. I see there is an option for Optimus so I've enabled it (disabling G-SYNC) and updated the article text. Re-running the battery life tests as well.
  • Junz - Friday, April 26, 2019 - link

    No problem. I feel like I get around 6-7 hours from a full charge while running something like dev-c++ and music/YouTube playing in the background. I can't wait to see your results though.

    Wish Acer would just use Intel branded network adapters in these systems. It feels like a frisking rather than a premium experience to buy at the highest end, but get saddled with Killer NICs.
  • Brett Howse - Friday, April 26, 2019 - link

    Killer uses Intel as their base adapter now and this laptop uses the 1550 Killer which is based on the 9260 Intel

    Yes, I'd heard that was the case. The trouble is that as with any rebranding effort, a company that purchases and resells has to perform some sort of markup in order to turn over a profit. That's where Rivet Networks (RN) sits, as a middleman business between Intel and the OEMs. Normally these in-between companies offer the prospect of added value, but RN's offerings of additional software don't generally improve on vanilla Intel adapters by offering useful features. A lot of us with networking backgrounds and people that have picked up the basics of how packets find their way to the end destination and back remain unconvinced that software prioritization at the NIC makes a measurable difference and there is a dearth of supporting numbers to prove otherwise. Meanwhile features like ethernet adapter teaming (market speak - DoubleShot) are not new features and have little reason to be implemented at an endpoint node that mainly performs consumer computing. Rivet has worked at stabilizing their software so at least that problem is not as pronounced as it was in the past and the switch to buying Intel was probably a good move from a driver standpoint, yet Killer NICs selling points appear to prey on a lack of knowledge and have that snake oil flavor. I'd hope Rivet finds a different, more meaningful way to add value so they can earn the premium level the company is hoping to achieve. Before that can happen, something fundamental needs to change about what they're offering and how they're offering it....or someone needs to post some numbers that put the proof in the pudding about the claims they're making.

    Acer has known reliability issues, what I'd really like to see is stress testing, since you are apparently gonna keep advertising their products. I've never had an Acer anything last more than 2 years. With that said it has been a while exactly for that reason. So, I say, abuse the keykoard, open the screen 1000 times, slide the thing off couches onto tile and carpet. Throw it in a backpack and act like you're a train commuter, pick it up, shuffle it around, toss it back down 1000 times.

    Until this kind of testing is done on Acer I'll never give them another cent. I just don't trust anything they make. Regardless of the components inside, assembly and quality build matter.

    I've had mine for 2 weeks and what your describing is pretty much how mine is treated and so far it seems pretty sturdy. Even dropped my back pack on the floor once and freaked out when I heard the loud metallic thunk but it held up pretty well. I don't know how it'll be in 2 years but I haven't had a laptop last me 2 years yet(I'm pretty rough with my electronics), only time will tell how this one holds up.
