The ASUS ROG Phone 2 received a lot of improvements over its predecessor. The device has a significantly larger display as compared to the ROG Phone, and aside from that, it has an upgraded refresh rate of 120Hz, which smoothens your gaming performance more than the 90Hz. Both of the devices also sport a Corning Gorilla Glass 6, which should be very useful for people with butterfingers.

Powering the ROG Phone 2 is Qualcomm’s latest flagship chipset — the Snapdragon 855+. Compared to the ROG Phone’s Snapdragon 845, it comes with a faster CPU performance and better gaming capability. Also, if you think that 8GB of RAM is enough to power a gaming smartphone, ASUS took it to the next level and upgraded it to 12GB.

Another thing to note is that the ROG Phone 2 has a UFS 3.0 storage which better than ROG Phone’s UFS 2.1. This simply means that the former is faster and better in terms of file reading and writing speeds.


In terms of cameras, the ROG Phone 2’s rear shooter configuration comes from the cameras of the ASUS ZenFone 6. The rear and front camera resolutions are higher than the ROG Phone; however, the number of MegaPixels doesn’t automatically determine which phone has better photo quality. We’ll know more once we test out both devices if we manage to get our hands on them.

A lot of features have also been upgraded in the ROG Phone 2. The AirTrigger 2.0 is more accurate and more responsive, which is great. Not only that the ROG Phone’s single Advanced vibration now has two, which is more immersive when playing games. The detachable AeroActive Cooler also gets an upgrade giving it bigger fans which also made it bulkier.

What’s pretty impressive is that the ROG Kunai Gamepad can be connected to the TwinView Dock II to make it function like the Nintendo Switch console. This isn’t the first time we’ve seen this as the BlackShark 2 also introduced this accessory but without the second screen.

If you thought that the 4,000mAh or 5,000mAh battery is enough to power a gaming smartphone, then you’re pretty much wrong. ASUS made it a point that you wouldn’t lack in battery life by putting in a massive 6,000mAh in the ROG Phone 2. Aside from the HyperCharge technology and 30W QuickCharge 4, it now comes with a 10W Reverse Charging, giving it the capability to charge other devices.

Here are the prices of each smartphone in Taiwan at launch:

  • ROG Phone – NTD 31,990 (8GB + 512GB)
  • ROG Phone 2 – NTD 26,990 (12GB + 512GB)

Looking at the Taiwan pricing, ROG Phone 2 is made more affordable than the original price of its predecessor, the option of getting this gaming beast should be considered. Do note that this doesn’t officially reflect pricing in the Philippines as it is yet to arrive in the country and is subject to taxes and duties.

So, should you get it? If you’re an existing ROG Phone user or a new buyer, and not concerned about the budget, then go for it as it will be worth the upgrade. But if you want to settle with the predecessor, that’s not bad as well as it can still go toe-to-toe with other 2019 flagship devices, especially when it comes to running heavy graphics games.
