One of Dell's Black Friday deals is a 15" XPS which can be configured with a FHD screen, Core i5-9300H, 8GB RAM, 256GB SSD, GTX 1650, and a 97 WHr battery for $1300.
When not using the GPU you should see similar results to those from Notebookcheck. Depending on how intensely you are gaming (and how hard the CPU and/or GPU throttle) 2 1/2 hours of gaming might be a reasonable expectation. I don't see an option to have a 4K screen, but if you find one expect battery times to drop by roughly half.
Battery Life
With its large 97-Wh battery and the low power consumption, we register an excellent battery life. In the WLAN test with an adjusted brightness of 150 nits, the entry-level XPS lasts for more than 14 hours, which is almost 7 hours longer than the OLED version of the XPS and more than 4.5 hours longer than the IPS 4K model. In the video test, our test unit even lasts for 17.5 hours.
At maximum brightness, the runtime in the WLAN test is still an excellent 10:40 hours. There is no quick-charge function, and it takes 2.5 hours to completely recharge the battery.
