Lenovo Yoga 9i (14, Gen 9) review – fast, solid, and beautiful

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.

The cooling of the Yoga 9i (14, Gen 9) is beefier compared to the one of the Zenbook 14 OLED (UX3405). That’s why the Core Ultra 7 155H inside of the Lenovo laptop can show higher clocks and lower CPU temperatures, especially when it comes to longer loads. This leads to better overall performance.

Comfort during full load

In “Extreme Performance” mode, the fans are noisy but still, they aren’t too intrusive. If you want to hear less noise, you can select the “Intelligent Cooling” preset and tick the auto transition to the Extreme scenario. In this case, the fans’ speed is less aggressive in not-so-demanding tasks and you can enjoy the full power of the CPU when you need it. It looks like the heat gets dissipated as fast as possible because the keyboard doesn’t feel hot at all when the CPU is doing the heavy lifting.

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. The 75Wh battery pack lasts for 12 hours and 30 minutes of Web browsing, or 11 hours and 7 minutes of video playback. To achieve that, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu and select the “Intelligent Cooling” mode in the Lenovo Vantage app.

Video playback

Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
