The Asus ROG Phone 2 is set to be unveiled next week on 23 July, but surprise surprise, the gaming smartphone just appeared in TENAA’s database. Naturally, several key specifications of the upcoming phone are also revealed in the certification.

Among them is the battery capacity of the ROG Phone 2, which is stated to be a whopping 5,800mAh cell. Needless to say, that is a very, very generous battery size – fitting for a gaming smartphone.

Despite the huge battery capacity, the ROG Phone 2 isn’t all that thick. Sure, with a 9.78mm chassis, it’s not particularly slim either. But looking at the side profile of the phone in TENAA’s listing, it should be thin enough to not feel cumbersome to use.

Besides that, the TENAA listing also states that the ROG Phone 2 is 170.99mm tall and 77.6mm wide. Without a doubt, it is quite a large smartphone. For comparison’s sake, the original ROG Phone measures 158.8 x 76.2 x 8.3 mm.

But the ROG Phone 2 does seem to utilise the space relatively well. Based on leaked images of the phone, the top and bottom bezels of the 6.59-inch display are quite minimal. While the TENAA listing does not mention the exact resolution of the screen, we do know it features a fast 120Hz refresh rate.

Looking at the back panel of the ROG Phone 2, it looks…similar to the first iteration of the device. There’s still a dual camera system, the ROG logo looks to be illuminated still, but there is one thing missing here: a fingerprint sensor. Chances are, the ROG Phone 2 will come with an in-screen fingerprint sensor.

Given the similar design of the ROG Phone 2 with its predecessor, we reckon the “AirTriggers” are retained on the upcoming phone. Basically, the AirTriggers act as shoulder buttons (via the use of ultrasonic touch sensors) when you’re gaming in landscape mode. If this feature is actually present on the ROG Phone 2, we reckon it will work very well based on our time with the first ROG Phone.

Even though the TENAA listing did not reveal the chipset that will power the ROG Phone 2, we already know it will be one of the first smartphones to feature Qualcomm’s latest Snapdragon 855+ chipset. With an overclocked CPU and GPU, gaming on this smartphone should be very enjoyable.

The Asus ROG Phone 2 is shaping up to be a really interesting gaming smartphone; the most exciting one yet, perhaps. We’ll learn more about the device once it is made official on 23 July next week.
