The Asus ROG Phone 3 is one of the most important gaming phones ever made, and its full specification sheet leaked through Taiwan’s NCC certification weeks before launch. That leak turned out to be almost entirely accurate. This guide walks through every confirmed spec, from the 144Hz display to the 6000 mAh battery, and looks at whether the phone still makes sense in 2026.
Before the ROG Phone 3 went official, we tracked every rumor in our roundup of the Asus ROG Gaming Phone 3 design and spec leaks. The NCC filing below confirmed most of what fans expected.
The NCC Certification Leak
In early July 2020, the Asus ROG Phone 3 passed through the Taiwan NCC Certification, and the filing revealed key hardware details. The charger adapter carried model number A299-200150U-US, while the battery was listed as model C11P1903. Together they confirmed 30W fast charging support and a massive 6000 mAh battery, exactly what hardcore gamers wanted for long play sessions.
The NCC documents also hinted at 512GB of onboard storage, which would be enough for a large game library. Later listings added weight to the rumors of a Qualcomm Snapdragon 865 Plus chipset, an overclocked version of the 865 found in flagships from the same year.
Display and Design
Asus equipped the ROG Phone 3 with a 6.59-inch AMOLED panel running at 144Hz, which was ahead of most phones in 2020. The screen supports HDR10+ and a 270Hz touch sampling rate, so touches register almost instantly in competitive titles. Corning Gorilla Glass 6 protects the front, and the design keeps the aggressive ROG aesthetic with RGB lighting on the back.
The 144Hz panel was a major selling point at launch. If you want to know which games actually take advantage of it, check our list of games that support 144Hz refresh rates on mobile.
Performance and Gaming Features
Inside, the ROG Phone 3 runs on the Qualcomm Snapdragon 865 Plus with the Adreno 650 GPU. The prime core clocks up to 3.09 GHz, and the integrated X55 modem brings 5G support. Paired with up to 16GB of LPDDR5 RAM, the phone handled heavy games without breaking a sweat in its prime.
Asus also included its AirTrigger 3 ultrasonic shoulder buttons, which map to in-game actions for a controller-like feel. The GameCool 3 system uses a 3D vapor chamber to keep thermals in check during long sessions, and dual front-facing speakers deliver loud, stereo audio.

Battery and Charging
The 6000 mAh battery was the biggest in any flagship of its generation, and it delivered easily a full day of heavy gaming. The 30W HyperCharge adapter tops it up quickly, going from empty to around 70 percent in about 40 minutes. Wireless charging is missing, which the leak correctly predicted, so you will rely on the cable.
Cameras
Gaming was the priority, but the ROG Phone 3 still shipped a capable triple camera. The 64MP main sensor (Sony IMX686) is joined by a 13MP ultrawide and a 5MP macro lens, while a 24MP shooter handles selfies. Photos are solid in daylight, though the camera was never the phone’s headline feature.
Software and Updates
The ROG Phone 3 launched with Android 10 and later received Android 11 and Android 12. Asus confirmed that Android 12 is the final OS update, with the last security patch arriving in September 2022. That means the phone no longer receives new features or security fixes, which is the main trade-off of buying one today.
Is the ROG Phone 3 Still Worth It in 2026?
Six years after launch, the ROG Phone 3 is only worth considering as a budget used gaming phone. The Snapdragon 865 Plus still runs most games at solid frame rates, and the 144Hz screen remains excellent. However, the lack of software support and aging battery mean it lags behind newer options for daily use.
