The Surface Pro has never looked better

The Surface Pro has never looked better
Welcome to a laptop battery specialist of the Hp laptop battery
The new PixelSense display on the Surface Pro 4 is stunning. The 2736 x 1824, 12.3-inch screen is bright, colorful and simply a joy to look at. When I watched the trailer for MTV's The Shannara Chronicles, everything from the turquoise Elfstones to the blood-soaked orcs looked sharp and vivid.
With an average screen brightness of 382 nits, the Surface Pro 4 is brighter than any Surface yet, and more luminous than its competition. The Spectre x360 (339 nits), Satellite Radius 12 (338 nits) and the 13-inch Macbook (334 nits) were close, but still noticeably dimmer.
The Surface Pro 4's color accuracy is nearly perfect with battery such as Hp HSTNN-C17C battery, Hp NBP6A48A1 battery, Hp EX940AA battery, Hp HSTNN-0B46 battery, Hp HSTNN-XB32 battery, Hp HSTNN-Q21C battery, Hp G6060EG battery, Hp G7000 battery, Hp Pavilion dv2100 battery, Hp Pavilion dv2200 battery, Hp Pavilion dv2300 battery, Hp Pavilion dv2500 battery, achieving a Delta-E rating of 0.35 (numbers closer to zero are better). The Toshiba Satellite Radius 12 and HP Spectre x360 were less accurate, but close, with Delta-E ratings of 0.6 and 1.25. The Macbook was a good deal worse, with a rating of 4.3.
Editing photos is a pleasure with a color range that almost perfectly covers the sRGB spectrum (99.7 percent). HP's x360 has a slightly wider color range, at 103.2 percent, while Toshiba's Radius 12 was almost identical, at 100 percent. The 13-inch Macbook Air was much more limited, at 65.8 percent.
Traditional laptops could learn a thing or two from the Surface Pro 4, whose dual, front-facing speakers positioned on either side of the screen project audio toward your ears, instead of to the sides or into a desk like some other systems do. The speakers aren't superloud, but they can fill a medium-sized room pretty well, and there's almost no distortion. Like many portable systems, the SP4's speakers are a little weak on bass, but otherwise, audio is pretty balanced. When I listened to Major Lazer's "Lean On," I found the mids and highs to be quite crisp, although I missed the depth and impact I was used to hearing in the bass line.
The Surface Pro 3 had problems staying under our 95-degree-Fahrenheit comfort threshold, and so does the SP4. On the Laptop Mag Heat Test, which involves streaming 15 minutes of HD video, the bottom edge of the Surface Pro 4 reached 101 degrees. In back, the left side of the tablet measured 100 degrees, while the right was slightly cooler, at 96 degrees. Overall, temps aren't high enough to be painful, but may cause some sweaty palms if you're using the device as a tablet.
Ports and Webcam: Same ports, but say 'Hello' to new cameras
Because Microsoft didn't want to make existing Surface Pro 3 accessories obsolete, ports haven't changed on the Surface Pro 4. You get a proprietary magnetic-charging port, one USB 3.0 port and a mini DisplayPort on the right; a combo headphone/mic jack on the left; and a microSD card reader hiding behind the kickstand in back. I would have liked to see an additional USB-C port somewhere on the system, though.
The front camera features the same 5-megapixel resolution as on the SP3, but now has Windows Hello facial recognition and the rear camera has been upgraded to 8 MP. Both cameras are capped at full-HD for recording videos.
Unlike a lot of low-rent front cams, the SP4's 5-MP front shooter takes a pretty decent photograph. In a picture snapped in our well-lit office, details in my hair and shirt were sharp and in focus. However, the camera struggled a bit with exposure, as the wall behind was blown out while the overall picture looked a little dark.
Microsoft has some work to do on the software for its rear camera. On two out of the three test units we received, there was noticeable pixilation and artifacts in the upper right corner of the camera window. Plus, the camera had trouble focusing on anything. On the third unit, the pixilation wasn't as obvious, but would crop up when moving the tablet around rapidly. The camera was also very slow to focus and adjust its exposure.
