The ROG Phone 2 had a very bold design, bringing a grey glass back with a load of red accents and air vents. This time around, things have been toned down a bit by reducing the colorfulness all around. 

The red and copper accents are now gone in favor of a muted grey design. Even the big vent is now replaced by a see-through glass which shows the cooling grill underneath. The RGB ROG logo sits in the centre, below the new triple-camera array.

Things don’t change by much on the front though. There’s a big display flanked by sizeable bezels which house the dual front-firing stereo speakers. The headphone jack is now gone, so you’ll have to resort to the included dongle for your 3.5mm earphones. Thankfully, the entire package doesn’t get any heavier and continues to tip the scales at 240 grams.

Gamers will appreciate the bigger shoulder buttons on the ROG Phone 3. The ultrasonic capacitive Air Triggers can even be split into two to act as four shoulder buttons in total. Along with taps, they also support swipes and long presses for additional input options.

Asus has pushed the display specifications each year with the ROG Phone. While the display dimensions don’t change, the refresh rate is bumped up to 144Hz with a 1ms response time. 

On the ROG Phone 3, we’re looking at a 6.59-inch AMOLED panel with a resolution of 2340 x 1080, with HDR10+ certification and an average Delta E <1. The touch latency has been brought down to 25ms for taps and 18ms for slides, which was at 49ms on the ROG Phone 2.

There’s also a Goodix in-display fingerprint scanner. The display is protected by Gorilla Glass 6. These specifications make the ROG Phone 3 the first in many countries to touch a refresh rate of 144Hz.

ROG Phone 3 vs ROG Phone 2 performance

Last year, Asus opted for a Qualcomm Snapdragon 855 Plus on the ROG Phone 2, which had a peak clock speed of 2.96GHz. With the ROG Phone 3, the performance should once again take a big step forward with the new Snapdragon 865 Plus. 

It is the first time the 3GHz threshold is crossed on a smartphone and is supposed to give about a 10% improvement in raw processing and graphics over its predecessor.

It is assisted by up to 16GB of LPDDR5 RAM and up to 512GB of UFS 3.1 storage to ensure that no component acts as a bottleneck for operations or gaming. To keep thermal throttling at bay, Asus has added a “GameCool 3” system which involves a multi-layer cooling structure consisting of a large graphite film, followed by a vapor chamber and a copper heat sink. 

The Aero Active Cooler attachment also gets a major facelift. It attaches to the secondary USB port on the side and acts as a circulator with 40% higher rpm than the last one. It also adds a headphone jack and a kickstand.

Cameras haven’t been the strongest point of the ROG series. The ROG Phone 2 had a simple dual-camera setup with a 48MP primary shooter and a 13MP ultra-wide lens.

 The ROG Phone 3 moves to a triple camera system with a 64MP f/1.8 primary cameras (Sony IMX686), followed by a 13MP ultra-wide shooter and a 5MP macro lens. Selfies are handled by a 24MP camera, that also employs pixel binning.

New shooting modes include video recording at 8K resolution at 30fps, 4K at 60fps, HDR, pro photo and video, HyperSteady, timelapse and directional audio recording.

The battery capacity of the Asus ROG Phone 3 is the same at 6,000mAh, but it brings a lot of improvements for battery health. Firstly, the 30W HyperCharger will be included in the box this time around. 

Moreover, it will also support Qualcomm’s Quick Charge 4.0 via a second IC on the phone. Within the Power Master app on the phone, the charging speed can be regulated to ensure battery longevity. Charging can also be scheduled or limited to a certain capacity to ensure long-term well-being.  

Takeaway

The Asus ROG Phone 3 build upon the already great ROG Phone 2 with meaningful improvements in many aspects. As with most flagships in 2020, it does go higher up the price ladder, but makes a fine case for itself for its target user.

Asus is not the only one vying for a piece of the growing eSports and smartphone gaming space. In the same week, we have the Lenovo Legion Phone Duel and the Nubia Red Magic 5S announcements, but their availability out of China is questionable. All of them sport the new Snapdragon 865 Plus and 144Hz displays.
