The ROG Phone 3, just like the ROG Phone II before it, has a 6000mAh battery capacity. Now, a leak has revealed that ASUS will once again go with a 6000mAh battery capacity for the ROG Phone 4.

Just a few flagship phones have a battery capacity of 5000mAh, so 6000mAh is more than sufficient for the ROG Phone 4. We also don’t see that battery capacity changing anytime soon. Seeing as battery capacity has remained unchanged over three generations, ASUS has decided to go with faster charging as the way to distinguish between the phones.

According to Digital Chat Station, the ROG Phone 4 will support 60W or 65W fast (wired) charging. This should allow users to recharge the dual-cell 6000mAh battery faster than its predecessor, the ROG Phone 3, which supports 30W fast wired charging.

When compared to other competing gaming smartphones that will also be launched this year such as the Black Shark 4 and Red Magic 6, the ROG 4’s 60W/65W fast charging is much slower than their 120W fast wired charging. However, its battery capacity is significantly higher than theirs which is just 4500mAh.

The ROG Phone 4 should also support reverse wired charging, Quick Charge 4, and Power Delivery. The phone is expected to arrive this quarter, which is at least four months earlier than the ROG Phone 3.

Just like other flagship phones, the ROG Phone 4 will have a Snapdragon 888 processor under its hood and support for 5G. Its AMOLED display is also expected to have a refresh rate of 144Hz or higher and it should run Android 11 out of the box.
