Lenovo ThinkBook 14 Gen 4 review – business in style
Source: Laptop Media EN→zh-CN
Lenovo ThinkBook 14 Gen 4’s IPS panel has a Full HD resolution, comfortable viewing angles, and a very good contrast ratio. The color coverage is quite limited (53% of sRGB), which makes the image look a bit dull. However, the backlight doesn’t use PWM for brightness adjustment. This results in a comfortable viewing experience at every brightness level. Unfortunately, the battery life is not good. At least with the smaller 45Wh package. We got 5 hours and 30 minutes of either Web browsing, or video playback. This is nearly a two-hour decrease compared to last year. Now, we can’t pass up the opportunity to mention the performance. It is not bad, but at the same time, could have been a lot better. With laptops like this one, you mostly rely on short-burst loads, where high clock speeds are pretty much essential. Yes, the device is chewing through every daily task you can think of, but you can never have even more speed, right? One thing that could have not even wished to be better is the port selection. You get plenty of USBs, one of which is a Thunderbolt 4 port. Add a LAN port, an HDMI connector, and an SD card reader, and you get all of the MacBook users in the office to envy you badly. Overall, what is really important in our view, is that the ThinkBook 14 Gen 4 is really comfortable to use. Its keyboard is spill-resistant and is a breeze, the display doesn’t strain your eyes excessively, and there is very little fan noise and heat coming from it. We think that it is a great addition to your workflow… provided you don’t need long battery life.
