- Surprisingly superb audio

- Solid performance, godlike battery life
- Conclusion: A lot to offer
Our other CPU test uses the free utility HandBrake to transcodes a feature-length movie to a format for Android tablet. This was once a practical, real-world test that’s become more abstract since Netflix allows you to download movies to PCs and tablets. Still, HandBrake has always served as a test of how the laptop holds up under prolonged load, and measures its ability to cool itself, too.
We weren’t sure how the Latitude’s Comet Lake chip would hold up in the 3DMark test, because of the two 10th-gen CPUs—Ice Lake and Comet Lake—only the former has what you might call a decent integrated GPU. The Comet Lake chip inside the Latitude 9510 runs on Intel’s famously unremarkable UHD Graphics, and it shows in the middling result it achieves in this test.
Some notebooks are defined by their performance—and the elevated clock frequencies enabled by the “Comet Lake” processor inside the Dell Latitude 9510 certainly boosted its performance. But the battery life is what makes this laptop special.
We loop a 4K movie over and over to test how long the system can remain powered up and active, keeping the brightness at a fixed, comfortable level. Most laptops fall within the 8 to 12-hour range, but the Latitude 9510...doubles that? Sure, a lot of that comes from the insane 86Wh battery, but, still! Twenty-three hours! That compares very favorably to laptops like the Lenovo Yoga C640-13IML, which lags far back in performance, but which we praised highly for its 16-plus hours of battery life.
The Dell Optimizer utility even lets you turn on an “adaptive battery performance” toggle, which promises to extend battery runtime based on the PC’s behavior. Toggling that on didn’t seem to adjust the display output, but battery life extended to about 25 hours. That’s simply incredible, and far beyond anything we’ve seen before.
Conclusion: A lot to offer
Right now, during a pandemic, true all-day battery life doesn’t mean as much when “mobile” means tromping from one room to another. We’d like to think, however, that the Dell Latitude 9510 will still be relevant as business travelers resume, well, traveling. Its price looks steep until you realize this is a business buy, usually designed to fit an IT department's budget, not one's own.
Do keep in mind, though, that this is a business laptop priced for business budgets, and it's being compared to laptops that are in some cases hundreds if not thousands of dollars cheaper. An IT department can justify all sorts of extravagant expenses in the name of business.
In a nutshell, though, the combination of solid performance, an even sturdier build, fantastic audio, convenient software options, and that superb battery life, earn the Dell Latitude 9510 2-in-1 to our unreserved Editor’s Choice endorsement.
