HP Spectre x2 was about the same
HP Spectre x2 was about the same
Welcome to a Vacuum Cleaner Battery specialist of the dell laptop battery
The XPS 12 pushed out 413 nits of brightness, even more than the Surface Pro 4's 382 nits, and a good deal greater than the HP Spectre x2's 322 nits and the 298-nit ultraportable average.
Dell's premium 2-in-1 also recreated an impressive range of colors, which covered 114.3 percent of the sRGB spectrum. That's more than the Surface Pro 4's more neutral 100 percent, and much wider than the HP Spectre's x2 77 percent.

However, the XPS 12 stumbled slightly on color accuracy with battery like dell 5208U battery, dell Inspiron 3700 battery, dell G5345 battery, dell Inspiron 1300 battery, dell Inspiron B120 battery, dell KD186 battery, dell Inspiron 5150 battery, dell Precision M20 battery, dell Precision M4300 battery, dell Latitude D531 battery, dell Precision M65 battery, dell Precision M60 battery, where it registered a Delta-E rating of 4.39 (closer to zero is better). Both the Surface Pro 4 and the HP Spectre x2 were more precise, with Delta-E ratings of 0.4 and 1.4, respectively.
Hidden behind cutouts on the top edge of the chassis, the XPS 12's stereo speakers put out a satisfying amount of volume, but struggled when recreating some low and mid tones. When I listened to Ratatat's "Cream on Chrome," I liked the Dell's crisp reproduction of the wailing Jamaican-inspired guitar, but the way the bass and percussion cracked and distorted made the band's funky beats hard to enjoy.
With the XPS 12, Dell has fully embraced the switch to USB Type-C by featuring two of the tiny rounded ports on the bottom left side of the tablet. Both ports support Thunderbolt 3 and can be used for charging, transferring data at speeds up to 10 Gbps, and pushing video to an external display. Dell also includes a microSD card reader for expandable storage, which is hidden under a little flap halfway up the XPS 12's left side, and a USB Type-C power adapter for charging.
When I used the 5-megapixel front camera to shoot a photo of my face, the camera captured accurate colors and details and even showed the content on a TV in the background. However, an unusually high amount of noise detracted from overall clarity.
The 8-MP rear cam also impressed, delivering accurate colors and the sharp details of a metal car and an owl figurine. But, as with the front cam, photos were noisier than I'd like or expect given the decent amount of ambient light.
Featuring a 1.1-GHz Intel Core m5-6Y75 CPU, 8GB of RAM and 128GB SSD, the XPS 12 had a difficult time keeping pace with faster detachables from Microsoft and HP (especially when it came to storage speed). Still, even with a big spreadsheet and 10 tabs open in Edge, the XPS 12 streamed a 1080p video from YouTube without a hint of lag.
In Geekbench 3, which tests overall system performance, the XPS 12 scored 4,875, well behind the $1,149 HP Spectre x2 with a Core m7-6Y75 CPU (5,814) and a $1,429 Surface Pro 4 featuring an Intel Core i5-6300U CPU (6,811).
On our OpenOffice spreadsheet test, the XPS 12 matched 20,000 names and addresses in 5 minutes and 13 seconds. Once again, the Surface Pro finished faster with a time of 4:11, although the HP Spectre x2 was about the same (5:34).
The real disappointment is the XPS 12's SSD. The 128GB drive recorded a transfer rate of just 82.09 MBps, while the SSDs in the Spectre x2 (149 MBps) and the Surface Pro 4 (318 MBps) were two to four times faster.
