Asus ROG Phone 9 Pro - The "Champion" of battery life
Asus continues to set the standard for battery life with its ROG Phone series. The latest product, ROG Phone 9 Pro, goes even further with an average usage time of 20 hours and 34 minutes in the battery test. This time is achieved when the phone's screen is set to the adaptive refresh rate.
Even with the screen at the highest refresh rate - 165Hz, the phone still lasts nearly 6 hours. The reason for the ROG Phone 9 Pro to achieve this is the 5,800 mAh battery and the energy-efficient Snapdragon 8 Elite chip. This chip will power many high-end Android phones next year.
In addition, the flagship also supports 65W fast charging, so users can save a lot of time. In tests, the device was able to charge 74% of the battery in just 30 minutes. Therefore, gamers can play games longer.
