Dell Latitude E6330 Battery all-laptopbattery.com


Laptop Screen Guide: Resolution, Refresh Rate, Color and BrightnessThe ZenBook S' touch-sensitive panel is responsive and fluid. I had no issues browsing the web by tapping and swiping my fingers on the glass. Unfortunately, the ZenBook S' reflective screen made its gorgeous picture difficult to see in our dimly lit office.The Asus ZenBook S' speakers sound good, but they don't get very loud. The laptop struggled to fill a large conference room when I played St. Vincent's "New York," but Anne Erin Clark's distinct vocals sounded crisp and clear. Death Cab For Cutie's atmospheric new single, "I Dreamt We Spoke Again," sounded lively, with ample slam to the drums. There was even a light bass thump when I listened to Drake's "In My Feelings." As expected from a laptop this small, the sound wasn't full, but I wouldn't consider it hollow, either.The angled keyboard on the ZenBook S felt more comfortable than the traditional flat keyboards I've used. My wrists were in a relaxed position, thanks to its gentle upward tilt. The keys remind me of those on the MacBook Pro, but better.



Asus ZenBook S UX391UA reviewAn ideal actuation force of 70 grams made up for the ZenBook S' low 0.9 millimeter key travel (our recommended range is 1.5 mm to 2 mm). Better yet, the keys are clicky, and the backlighting has adjustable brightness levels, which is not something we typically see on non-gaming laptops. Also, the keys are well-spaced (though a few are undersized).I achieved 115 words per minute at an accuracy of 96 percent in the 10fastfingers.com typing test. That's quicker than my typical 109 wpm average and a bit better than my average accuracy of 95 percent.The ZenBook S' smooth touchpad is responsive. I didn't have any problems executing numerous gestures, like scroll, pinch-to-zoom, or three-finger swipes to see all open windows. The touchpad has a built-in fingerprint sensor on the top-right corner.



Equipped with an Intel Core i7-8550U, 16GB of RAM and a 512GB SSD, the ZenBook S has plenty of power to run demanding programs or high-resolution videos. I noticed only slight lag when loading 21 Google Chrome tabs, two of which played 1080p YouTube videos and one that ran a 1080p Twitch stream. I then added a 4K-resolution YouTube video to the workload to see if I could stump the Ultrabook, but it booted up the clip without hesitation. The ZenBook S scored 11,611 on the Geekbench 4 test, which determines the general performance of a laptop. That beats the premium laptop average (11,052) but loses to top competitors, like the Dell XPS 13 (14,180), the Huawei MateBook X Pro (12,913) and the Apple MacBook Pro (17,572).The 512GB PCle SSD in the ZenBook S duplicated 4.97GB of mixed-media files in 16 seconds for a rate of 318 megabytes per second. The ZenBook S outpaced the Huawei MateBook X Pro (283 MBps) but couldn't catch up to the XPS 15 (508 MBps). The 2018 MacBook Pro has the Usain Bolt of hard drives, which reached an astounding write speed of 2,682 MBps.




The ZenBook S was a bit sluggish in our Excel Macro stress test, which involves matching 65,000 names with their corresponding addresses. It completed the task in 1 minute and 51 seconds, which is slower than the Dell XPS 13 (1:08), the Huawei MateBook X Pro (1:49) and the Apple MacBook Pro (1:17). The premium laptop average of 1:34 is also quicker.The ZenBook S' worst results came in our video-transcoding test, where we use Handbrake to convert a clip from 4K to 1080p resolution. The ZenBook S completed the test in a leisurely 37 minutes and 51 seconds, which is significantly slower than the premium laptop average (22:15). The Dell XPS 13 (16:00), the Huawei MateBook X Pro (27:18) and the Apple MacBook Pro (16:57) trounced the ZenBook S.



The ZenBook S isn't meant for gaming, but it can play less-demanding titles at low settings. The system's integrated Intel UHD Graphics 620 GPU scored a 80,332 on the Ice Storm Unlimited graphics test. That figure falls just short of the premium laptop average (83,517) and the scores earned by the Dell XPS 13 (85,616) and the Huawei MateBook X Pro (116,359).The ZenBook S didn't fare any better in real-world tests. It played Dirt 3 at 1080p resolution at 45 frames per second. Although that surpasses our playability threshold of 30 fps, it falls below the Huawei MateBook X Pro (117 fps), the Dell XPS 13 (67 fps) and the MacBook Pro (47 fps). The category average is a smooth 69 fps.



The Asus ZenBook S' battery life is below average. It lasted 7 hours and 5 minutes on the Laptop Battery Test, which involves continuous web surfing over Wi-Fi at 150 nits of brightness. Other premium laptops had longer runtimes, including the 14-inch Huawei Mate X Pro (9:55), the 4K version of the Dell XPS 13 (8:23) and the MacBook Pro (8:23). The premium laptop battery life average is 8:20. The ZenBook S' elevated hinge failed to adequately improve airflow in our testing. The notebook's underside reached 107 degrees Fahrenheit, and the location between the G and H keys warmed to 101 degrees when we played a 15-minute video at 1080p resolution. The bottom lower-left side was the hottest location on the laptop, reaching 111 degrees, which exceeds our 95 degree comfort threshold. Only the touchpad stayed cool at 87 degrees.




The ZenBook S' 720p webcam is solid. It captured a bright, well-exposed image in our dimly lit office, and its white balance and color reproduction were on point. The dark-red color in my shirt was true, and my light skin tone was accurately captured. For how bright the shot was, there was far too much visual noise, and details appeared blurry.The ZenBook S' Windows 10 Home OS comes pre-installed with an Asus folder filled with apps. Among the more useful programs are Asus Live Update, which installs the latest drivers on your machine, and Asus Splendid, which allows you to change the color temperature of your display. There is also a Quiet Fan app, but we'd keep the default "high-performance" setting turned on considering how hot the ZenBook got in our testing. McAfee WebAdviser also makes an unwelcome return.



The rest of the bloatware installed on the ZenBook S comes courtesy of Microsoft, including Netflix and LinkedIn apps.The Asus ZenBook S comes with a one-year warranty. See how the company performed on our Tech Support Showdown and Best and Worst Brands ranking.For $1,499, the 4K unit I reviewed came equipped with an Intel Core i7-8550U processor, 16GB of RAM and a 512GB SSD. Another version with the same processor but 8GB of RAM and a 256GB SSD costs $1,199. The Asus ZenBook S is available in Deep Dive Blue (dark blue) and Burgundy Red. The Asus ZenBook S is an extremely lightweight laptop with a gorgeous, premium design and a vivid 4K display. It has strong performance, although it doesn't stack up well against other premium laptops, like the Dell XPS 13 and 13-inch MacBook Pro. But those laptops don't have the ZenBook S' hinge, which makes its keyboard significantly more comfortable to type on.



Asus ZenBook S UX391UA reviewThe Asus ZenBook S is priced to sell at $1,499 for a Core i7 CPU, 16GB of RAM and a 512GB SSD. That puts it up against the 14-inch Huawei MateBook X Pro. Although the ZenBook S is lighter and sleeker, we prefer the MateBook X Pro for its longer battery life, snappier keyboard and wider variety of ports.We also suggest you consider the XPS 13. It has better performance and longer battery life than the ZenBook S, but you'll need to throw down $1,999 for comparable specs. That makes the ZenBook S an excellent value for anyone in the market for a premium laptop.A. Lithium-ion batteries have a limited life span and eventually wear out after a number of charge cycles, as opposed to wearing out over a particular number of months or years. Some companies, including Apple, measure a cycle as using all of a battery’s power, but not necessarily from a single charge.
