ASUS's Gaming Features

We explained that this is a gaming-oriented phone first and foremost, so we should of course cover its unique gaming features. Starting off with the physical, we should talk about the new AeroActive Cooler 3, ASUS’s active cooling solution for the ROG Phone III.

The accessory comes included by default with the phone which is a positive as it’s essentially the key add-on that’s supposed to make the ROG3 what it is.

The cooler accessory is quite light-weight at 38g and is made of plastic. It’s primarily made of two separate sections with the whole unit extending out to be able to grip around the phone when connected. The ROG logo at the back as well as the “Republic of Gamers” label on the front are RGB and light up in the same fashion as the ROG logo on the back of the phone.

The inside part of the cooler contains the dual USB-C connector that attaches to the phone, with the other side only having a little plastic hook that wraps around the side-frame of the right side of the phone, below the power button.

When holding the phone in landscape the cooler is well positioned and really doesn’t get into your way of things which is good – it does however significantly increase the size of the phone as a whole if you’re to carry it around in your pocket in this way.

The interesting aspect of the cooler is exactly how it cools the phone. This actually isn’t a fan that is supposed to be blowing air onto the back of the phone, as in the earlier picture you see that there’s essentially no ventilation holes that actually blow to that part of the phone. There’s also a noticeable gap in-between the cooler and the phone itself, and the tiny fan hardly generates enough pressure to get enough airflow at the phone’s surface.

What I think actually happens is that the AeroCooler is cooling the phone via the USB-C connectors. The combo-connector lies on the motherboard directly next to the SoC as well as the small metal heatsink underneath the back glass. My theory is that heat is being transferred from the motherboard through the quite large double USB-C connectors to the AeroCooler itself, which dissipates this internally and vents out through the slits on this side of the phone.

By the way, that small slit on the phone itself isn’t even covered by the AeroCooler vents, which further reinforces my notion that it’s just there for design and doesn’t have any practical use for cooling of the phone.

The AeroCooler has a 3.5mm headphone jack as well as a functional USB-C port. It’s a pity that this is the only way to get audio out of the phone – there’s no other 3.5mm adapter included in the box.


Software, wise, there’s two ways to take advantage of ASUS’s gaming features. In general use, you can switch the whole phone into “X-Mode” from the notification area toggle.

X-Mode has three settings levels by default here, LV1, LV2, and LV3, all differing in their performance and well as thermal limits tunings. LV1 merely boosts CPU minimum frequencies to a higher minimum, partly disabling “normal” DVFS operation. LV2 further raises these minimums as well as raises the thermal throttling temperature limits of the phone – in general LV1 will allow for skin temperatures up to 37°C, while LV2 will go up to around 45°C peaks.

LV3 will completely disable DVFS of the SoC and run the CPUs and GPU at maximum frequency all the time – the caveat here is that this mode can only be enabled when the AeroCooler is connected.

Beyond the global X-Mode settings, you can also fine-tune things via ASUS’s Armory Crate application, where you can set per-app profiles and in which you have a ton more options beyond the three X-Mode levels.

There are simplified controls in which you can set the three DVFS minimum control as well as thermal throttling limitations, or you can go fine-tune things via the advanced controls.

The advanced controls are indeed quite advanced and allow you to fully control essentially all DVFS tuneables of the CPU, GPU, memory controller drivers, as well as fine-tune the system schedulers and even I/O performance settings. Pretty much ASUS gives you full control over this aspect of the device, controls you usually only would have if you had rooted your phone.

The other important Armory Crate setting is the refresh rate configuration page where ASUS also exposes an anti-aliasing toggle for 4xMSAA, something that I think is very nice to have given a lot of games nowadays still don’t allow for full native rendering resolutions.

ASUS’s game engine is a in-game control panel which can be called up by swiping from the left of the screen while in an app or a game, and gives you various nifty features that might be useful to you while gaming.

The most important feature here beyond your slew of system setting toggles, performance settings shortcuts, and other gimmicks, is the ability to set up the air triggers of the phone and set their inputs to the game you’re playing.

The air-triggers are in my opinion still the single most important aspect of the ROG Phone III as a gaming phone as it really gives you that extra control ability, especially in 3D shooter games. This allowed me seamless moving, aiming, and shooting all simultaneously, which might be a little more hindersome on other traditional phones.

The one disappointing aspect of the phone in games was the refresh-rate: Although the phone goes up to 144Hz, there’s very little games out there which can actually take advantage of this. For example in the PUBG session above, the game still capped out at 60fps rendering, and given this is one of the most popular games on the market, it does more significantly reduce the value of the high-refresh-rate screen for gaming.

    Just love how far ASUS has come with its phones

    Yeah, in 2019... but this year they have gotten worse.
    Just compare the Zenfone 6 to the Zenfone 7 for starters.

    On the ROG 2 vs ROG 3,
    The new device is slightly larger, heavier, and lost the 3.5mm Jack. And it raised the prices.
    But comparing the 16GB RAM vs 12GB RAM, isn't that big deal. And the uplift from the QSD 855 to the 865/865+ is hardly impressive. Or the 5900mAh battery compared to the 6,000mAh battery. Even the screen is the same comparing 144Hz to 120Hz, or the 270Hz-Touch to the 240Hz-Touch. By most metrics the new model is the same or worse than the older one.

    And again, it's more expensive. I think that second chipset (Qualcomm's external modem) is the culprit for this year's lacklustre phones (larger, hotter, battery thirstier, less internal space, more expensive).

    The only point where ASUS has made a notable upgrade is in the camera. And that's on both the ROG 3 and the Zenfone 7. But it's hardly a reason for someone to choose to buy a new ROG3, when they could get the ROG2 on a discount.

    I think I could've been fine with the ASUS ROG 3, if they kept the 3.5mm headphone jack, added a microSD slot, and added wireless charging. That would've made the +$200 price hike easier to swallow. If they included JoyCons in the box, it would've been an instant hit.

    To be honest, I would've preferred they downsized it slightly to around (166 x 74 x 9mm) which is like the size of the OnePlus 8 Pro, any larger makes it unpocketable for most regular mens jeans/pants. Even if that means downsizing the 6000mAh battery down to 5000mAh battery, it's worth it for the quality of life improvement.

    When SD865 prices just got announced people were seeing a price hike of the handsets as inevitable. This phone looks decidedly less "gaming" than the predecessor and that's a big plus for me, and the second C port means the lack of the jack is at least tolerable. How they should cut corners on the optics so much confuses me, I'm wondering if this is a defective unit.
    There's rumor that Samsung is still contemplating bringing back the jack in flagships next year so I'm taking the wait and see approach, the S-Pen for me is worth it, but if Samsung doesn't follow through then I'll come back and buy one of these second-handed. With far superior battery to the Sony, it's already the closest thing to an all-rounder on the market.

    I'm thinking the next year's QSD 875 will be like 8% faster simply because of the 5nm advancement. Plus another 8% speed due to slight architectural improvement in the X1 core, and modem efficiency.

    Yes most important, it should have the 4G/5G modem integrated (hopefully)... and that should mean better efficiency, and slightly larger internal space. So we could see the 3.5mm Headphone Jack make a comeback because of that.

    But Samsung has killed the Jack for good. They have their own wireless earphones for sale. They got rid of it on the Note10 for no good reason. It's not coming back. Heck, even if they wrongly accuse the internal space restrictions, which is not true, there is no reason that they cannot integrate the 3.5mm Headphone Jack into the underside of the SPen.

    I'm hoping this year has negatively affected all OEMs that they re-introduce some wanted features next year like Headphone Jack, microSD... on top of REDUCING the prices down (-30% ?) to regular levels to ensure strong sales/continued sales. I think this year proved that marketing wasn't strong enough to deceive the consumers.
  • s.yu - Wednesday, September 2, 2020 - link

    lol I would bet on a comeback of the 3.5mm than a 30% price drop. Anyhow, the market hasn't exactly been exciting this year so I'm truly not in a hurry to upgrade, so I'll wait and see until there's something solid suggesting no jack again.

    Joycons are stupid, it should be a whole PSP-like controller case that locks in place, to literally turn your phone into a PSP. Then we can have serious game development and ports for phones.

    This should have been available since 2007 or before. 13 years later and we're still using weird flimsy attachable joycon things.

    The current Chinese Bluetooth psp-style controllers suck bad.

    The most awaited review is finally here
    Wanted to see how it fares against other flagships
  • Kishoreshack - Friday, August 28, 2020 - link

    6000 mah battery with 865 plus & 144hz display is an instant sell for me
  • nico_mach - Friday, August 28, 2020 - link

    Yes, this, I think this phone is more compelling outside of its gaming. Esp in comparison to iphones - they dominate the performance but usually ship with tiny batteries. Android phones need to carve out a niche, and this phone does that.
  • melgross - Monday, August 31, 2020 - link

    They still have some if the best battery life. And they’re not “tiny” batteries. iOS doesn’t need very large batteries as Androud phones do.
