ASUS Vivobook 15 OLED (X1505) review – when your display is doing the heavy lifting
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Compared to the 16-inch model, the Vivobook 15 OLED (X1505) provides higher clock speeds at the beginning of the test. In addition, the P-cores are preferred against the E-cores.
Comfort during full load
In terms of comfort, the laptop doesn’t produce too much noise even during extreme workload scenarios, while the maximum temperature in the middle of the keyboard is just about 40°C.
Battery
Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. This device features a 50Wh battery pack. It lasts for 10 hours and 25 minutes of Web browsing, or 7 hours and 40 minutes of video playback.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
