The ASUS ROG Strix G15 (G513QY) Review: Embracing AMD's Advantageby Brett Howse on May 31, 2021 11:00 PM EST
Although generally less of a hinderance for gaming systems, which are most often used on a desk and connected to power, AMD has stated that the Radeon RX 6800M is able to go into a “Near 0 Watt Idle” state, meaning despite having a massive 150-Watt TDP GPU inside, battery life should not be compromised as severely as it is on other gaming systems.
ASUS outfits the G513QY with a 90 Wh battery, which is near the limit of what is allowed in a laptop, so that, coupled with the 7 nm CPU, and a power-gated GPU, should provide good results.
Web Battery Life
As much as the performance has been amazing on the AMD CPU and GPU combination, perhaps the battery life result is even more impressive. Typically, gaming systems are not very efficient, as even the systems that do allow the GPU to be disabled during light tasks still have a high base power draw, but AMD has really done amazing work to power gate the GPU when it is not needed. When coupled with the very large battery, the ASUS Strix G513QY dominates the battery life charts compared to other gaming-focused systems.
Looking at the platform efficiency with the battery size removed, the ASUS G513QY proves that the amazing battery life is not just down to the 90 Wh battery either. AMD has really done a fantastic job with system power with the Ryzen 9 5900HX and Radeon RX 6800M combination.
PCMark 10 Modern Office Battery
One of the newer tests to our laptop suite is the PCMark 10 Modern Office battery test, which leverages the same workloads in the PCMark 10 benchmarking suite, and then runs them in 10-minute loops. If the system gets the work done quicker, it is able to idle for a larger portion of the 10-minute window, so that more performant systems are not disadvantaged. Once again, the battery life is really astounding for a system of this type.
On thin and light laptops, movie playback is generally the most efficient task, since the media decode is offloaded to the media block. On the ASUS, the battery life was actually slightly less than the other tests, but still well ahead of most other gaming systems.
The Tesseract score divides the movie playback runtime by the length of The Avengers movie, and the ASUS G513QY can almost get through four complete viewings before needing to be recharged.
Thanks to a 280-Watt AC adapter, there is plenty of power available to charge the battery quickly, even if the device is in use. Interestingly, the ASUS G513QY also includes a USB-C port on the rear which supports up to 100 Watts of power delivery, and that can go both directions. You can charge something from the port if needed, but the power delivery also allows the laptop to be recharged from external battery packs if needed, or from a USB Type-C charging cord. It will not be able to delivery the full power for when the system is under load, but still makes for a nice backup power source if needed.
The charge rate is very quick on this system. Despite the large 90 Wh battery size, the system recharged the quickest of the sampled systems. ASUS claims 0-50% in less than 30 minutes and we measured 31 minutes to 50%.

DoofusOfDeath - Saturday, June 5, 2021 - linkThanks, and bummer. Do you remember where you found that info? I was having trouble hunting down the specs.
Brett Howse - Sunday, June 13, 2021 - linkIt was in the reviewer's guide AMD sent.
watzupken - Thursday, June 3, 2021 - linkThis reviews proves the point that PC makers should really consider giving a higher resolution monitor for a high end laptop. Its pointless to give a 1080p with very high refresh rate because the GPU will easily be bottlenecked by a mobile CPU. Also the high refresh rate, i.e. 300Hz, is equally if not more taxing on the battery than say a 1440p monitor with a 144Hz refresh rate.
BlakeCz - Thursday, June 3, 2021 - linkIn my opinion full HD for 15.6-inch screen is sufficent (If it was 17-inch that is a different story). And you still have enough horsepower if you connect external LCD.
inperfectdarkness - Thursday, June 3, 2021 - linkYou are blind. I can easily tell the difference between 1080p and 3k on a 15.6" laptop. 1080p has never been sufficient. Never will be. 1440p should be the minimum standard. Period.
And the entire point of a gaming laptop is so you can use it on trips, not so you can lug a 30" 4k display around to plug into it to compensate for the god awful screen that it comes with.
Tams80 - Saturday, June 5, 2021 - link'Easily' my arse.
Sure, you can tell if you start looking for it, it in normal use and especially while playing a game you are very unlikely to notice. You are going to notice not hitting high framerates though.
Spunjji - Monday, June 7, 2021 - link@Tams80 - I'll second the "easily" comment, although the flip side is claiming that 1080p has "never" been sufficient is obviously nonsense, it was good for a while. For me, 1440p at 150% scaling is instantly recognisable as better than 1080p at 100% on the same display size, though.
With a GPU / CPU pairing like this, frame rates are going to be near-identical between 1080p and 1440p in most extant titles.
Bernecky - Thursday, June 3, 2021 - linkBack in The Dark Ages, when we were confined to a single planet by gravity, reviewers
would publish the mass (or weight, if we were grounded) of the reviewee. For normal
systems, we can use forklift to move the thing, but for supposedly "mobile" systems,
knowing the thing's mass is something we need to know before making a purchase decision.
Hrel - Thursday, June 3, 2021 - linkIn this age and at that price a 512GB SSD is totally inexcusable.
