Microsoft Surface Laptop Go 3 review – A Portable Powerhouse with a Few Caveats
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 Core i5-1235U inside this Microsoft device can maintain surprisingly low clocks in short loads which isn’t a surprise since the fan is dead silent. In medium load, when the fan becomes slightly audible, the frequencies are adequate. In the long run, the P and E core clocks are low but yet higher than the official minimums.
Comfort during full load
During 100% CPU loads, the left and the central part of the keyboard feel averagely hot to the touch but you can use the device comfortably for work. At the same time, you can hear the fan but the noise isn’t too loud at all.
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 notebook’s 41Wh battery lasts for around 9 hours of Web browsing, or 8 hours 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.
