Welcome to a laptop battery specialist of the dell laptop battery
Our $1,349 configuration packs an Intel Core i5-3247U processor, 4GB of RAM and a 180GB SSD, also made by Intel. If raw numbers are any indication, it's just as fast as, if not faster than most Windows 8 systems we've tested. Its PCMark 7 score of 4,762 is slightly higher than what we've seen from other machines, while the solid-state drive is among the speediest (the Acer Aspire S7's RAID 0 setup notwithstanding). In particular, it notched peak read speeds of 553 MB/s and max writes of 519 MB/s, according to the benchmark ATTO. As it happens, we've seen a few other Windows 8 systems with similar read rates (the Dell XPS 12, Toshiba Satellite U925t and Acer Iconia W700, for example), but most can't compete when it comes to write performance.
Speaking in more practical terms, the machine starts up in 11 seconds, which is just slightly faster than what we've seen in similarly configured systems. (Note: we're talking 11 seconds versus about 12, so the difference is actually negligible in practice.) In general, too, the machine was able to keep up as we jumped from app to app, and was quick to launch new programs.
As for graphics performance, the Folio appears to be merely average: its scores fall right in line with other Ultrabooks using Intel's integrated HD 4000 graphics solution. Which is to say, you can get away playing an older, not-too-graphically-intense game so long as you refrain from maxing out the settings. Even then, you'll be lucky to hit 30 fps.
Now this is more like it. Just when we were starting to wonder if Windows 8 machines were all cursed with short battery such as Dell 451-11508 battery , Dell 453-10049 battery , Dell 312-0650 battery , Dell Studio 1535 battery , Dell Studio PP39L battery , Dell KM965 battery , Dell WU965 battery , Dell 312-0769 battery , Dell KM970 battery , Dell PP32L battery , Dell Latitude E5400 battery , Dell Latitude E5510 battery life, we started testing a couple winners. First there was the Acer Iconia W700, a laptop / tablet hybrid that lasts seven-plus hours. Now we have the EliteBook Folio, which managed six hours and 18 minutes in our battery rundown test (video looping, WiFi on, brightness fixed at 65 percent). If you look at the table above, you'll see that's among the best showings we've seen from an Ivy Bridge Ultrabook of any size.
Granted, we fully expected the Folio would do better than a touchscreen machine, since touchscreens are known to take a terrible toll on battery life. Still, it fares considerably better than other non-touch Ultrabooks, including the ASUS Zenbook Prime UX51vz and the ThinkPad X1 Carbon.
