HP ProBook 445 G7: A darker display in exchange for better battery life

A longer battery life sunk the max display brightness: The HP ProBook 445 G7

More experienced users can do a lot to influence battery life for the better, but less experienced users may not know how to adjust default manufacturer or driver settings.

HP actually did a lot well with the ProBook 445 G7, which has an AMD Ryzen 5 4500U CPU inside. Its keyboard would be great even for prolific writers, its housing is robust, and it has a mechanical webcam cover to boot. While the frame above the screen is a little bigger so that the infrared cameras required for facial recognition can fit, it is not really a huge problem. 

Since users can add a second RAM chip and a SATA mass storage device, the somewhat lower GPU performance of the AMD Radeon RX Vega 6 due to it only working in single-channel mode is not as problematic. The CPU's performance does not quite meet the full potential of the AMD Ryzen 4500U, but it is still quite good.

How was the battery life achieved?

In our practical WLAN test, we set the brightness of each laptop screen to a measured value of 150 cd/m². With this brightness setting, the ProBook 445 G7 achieves a battery life of almost nine hours; this long battery life could be a huge, everyday benefit for people who, for example, work in an office and need to carry their laptop around with them all day.

Users who would like to use their laptop outdoors, however, need to use a much higher brightness value because the brighter ambient light has to be overcome by the screen's brightness. The HP laptop can meet this need while plugged in. The IPS panel installed in our test device was able to achieve an average of 270 cd/m², which significantly exceeds even the manufacturer's own specification of 220 cd/m².

If you are looking to work outdoors, though, you are going to be disappointed. The brightness while in battery mode can only reach a maximum of 168 cd/m². This brightness value is only slightly higher than the 150 cd/m² that we think is sufficient for office environments. When running on battery, the Vari Bright function of the AMD Radeon settings takes effect. To increase battery life, the Vari Bright function automatically reduces the contrast and brightness of the screen, which is not ideal in every situation. Users must therefore deal with changing their system settings around when they move to a new environment in order to achieve optimal results.

Our detailed test report shows why the HP ProBook 445 G7 could still be a good choice when using our test configuration, though.

I carried out my first IT experiments with a 386-based system and a whole 4 MB RAM. This was followed by work on various PCs and laptops that I maintained and repaired for friends and acquaintances. After training to become a Telecommunications Systems Technician and gaining a few years of experience, I graduated with a Bachelor’s degree in Industrial Engineering. Currently, I pursue my fascination for IT, technology, and mobile devices by writing reviews and articles for Notebookcheck. I have also worked for Gamestar, Netzwelt, and Golem, among others.
