Lenovo IdeaPad Slim 5 (16″, 2023) review – a better, slightly more expensive version of the IdeaPad Slim 3

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.

Average core frequency (base frequency + X); CPU temp.

This notebook performs pretty well in the stress test. It is good to see that Lenovo lets it run at quite high temperatures, and does not limit its performance.

Comfort during full load

Thankfully, the high internal temperatures don’t translate to high external ones. Also, the noise levels of the machine are extremely low, even in the scenario of a continuous stress test.

Battery

Now, we conduct the battery tests with 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. Our unit is equipped with the largest available battery for this model. It has a capacity of 75.4Wh and lasts for 14 hours and 10 minutes of Web browsing, or 10 hours and 44 minutes of video playback.
