Dell Latitude 14 5440 review – surprisingly good
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.

Interestingly, the Core i7-1355U inside the Latitude 14 5440 can boost higher in any kind of load compared to the more premium Latitude 14 7440 with the same CPU. Moreover, we are talking about ~4GHz for the P core and ~3.00GHz for the E cores in short and medium loads – nice! In prolonged periods of 100% stress, the frequencies are one of the highest we’ve seen for an i7-1355U.
Comfort during full load
You have four presets for controlling the laptop’s performance. In “Ultra Performance” mode, when the CPU is loaded at max, the noise is average which is fine. At the same time, the keyboard isn’t scorching hot to the touch – it feels a bit warm.
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 14 hours and 17 minutes of Web browsing, or 8 hours and 20 minutes of video playback. The result is definitely 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.
Luminozitate: 180 nits; Mod Afișaj: SDR

Dell’s battery life is so horrible. I will be very happy if it lasted 2 hours. We have several Latitudes and Precision laptops.
Très mauvais produit.
Au bout de 6 mois touche E du clavier illisible car peinture partie. Pas pris en charge par la garantie!
