The Precision 7520's large 6-cell, 91Wh battery lasted an impressive 6 hours and 28 minutes on the LAPTOP battery test (continuous surfing over Wi-Fi at 100 nits brightness).
That's better than the category average (128,747) and ahead of both the 137,005 of the Lenovo ThinkPad P51 (Nvidia Quadro M2200) and the 143,124 of the Dell Precision 5520 (Nvidia Quadro M1200) and the HP ZBook 15 G4's 151,677 (Nvidia Quadro M2200). On 3DMark Ice Storm Unlimited, a synthetic graphics benchmark test, the Dell scored 156,543. With its Nvidia Quadro M2200 and 4GB of VRAM, the Precision 7520 is a workhorse built to handle 4K video editing and 3D modeling that would overwhelm lesser office PCs. On the typing test I was able to match my 80-word-per-minute average without any trouble. The Precision 7520 has a full-size backlit keyboard with a 10-key numeric pad, and the 1.7-millimeter (1.5 to 2mm is typical) key travel makes for a very comfortable typing experience. And it was drastically better than the uncalibrated Lenovo ThinkPad P51 (11.93). That's even better than the very good HP ZBook 15 G4 (0.27), the MSI WE72 7RJ (0.4) and the Precision 5520 (1.5). The color accuracy, on the other hand, was nearly perfect with a Delta-E rating of 0.09 (0 being a perfect score). We saw wider color gamuts on the HP ZBook 15 G4 (171.6percent), the Lenovo ThinkPad P51 (172 percent), the Dell Precision 5520 (113 percent) and the MSI WE72 7RJ (196 percent). However, it's not uncommon to see displays exceed the 100 percent mark as they offer color ranges beyond the standard sRGB gamut. It has good color as well, producing 99.9 percent of the sRGB color spectrum.
