Dell Latitude 15 5540 review – tuned for comfort

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 P-core frequency; Average E-core frequency; CPU temp.; Package Power

The optional Core i7-1355U inside Latitude 15 5540 can maintain impressively high clocks in short loads. In prolonged periods of 100% CPU stress, the CPU can sustain almost the same frequencies as the more premium Latitude 16 7640.

Comfort during full load

The power presets are located in the BIOS. In “Ultra Performance” mode, the fan is almost quiet even in full processor loads. At the same time, the keyboard deck doesn’t feel hot to the touch so you can use the machine comfortably for work.

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 54Wh battery pack lasts for 12 hours and 30 minutes of Web browsing, or 8 hours and 20 minutes of video playback. The result is good. To achieve that, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu and select the “Optimized” power plan in the BIOS.
