Welcome to a laptop battery specialist of the dell laptop battery
In a world full of sleek and slim Ultrabooks, the Dell Inspiron 15R 7520 looks enormous. This 15.6-inch laptop is bulky, heavy (7.4 pounds), and not terribly stylish. But it does have some surprises under the hood—namely, four USB 3.0 ports, a full HD screen, and solid overall performance.
Our review model, which costs $1100, sports a third-generation Intel Core i7-3612QM CPU, 8GB of RAM, and a 1TB hard drive spinning at 5400 rpm. It also features an AMD Radeon HD 7730M discrete graphics card, built-in Bluetooth 4.0 and Wi-Fi 802.11n, and a Blu-ray Disc player. The Inspiron 15R 7520 runs the 64-bit version of Windows 7 Home Premium.
Performance
In PCWorld's WorldBench 7 benchmark tests, the Inspiron 15R 7520 did well, earning a score of 137. This score means that the Inspiron 15R 7520 was 37 percent faster than our standard testing model, which carries a second-generation Intel Core i5 with battery such as dell C852J battery, Dell Alienware M17X Battery, Dell WW12P Battery, Dell Inspiron DUO 1090 Battery, Dell YY9RM Battery, Dell CRKG5 Battery, Dell Studio 15Z Battery, Dell XP115 Battery, Dell D2340 Battery, Dell Vostro A90 Battery, Dell C901H Battery, Dell Y1909 Battery desktop processor and 8GB of RAM. Although 137 is a good score for the all-purpose laptops category, it isn't excellent: For example, the Alienware M14x, an all-purpose laptop designed for gamers, posted a mark of 143 on WorldBench 7.
The Inspiron 15R 7520 performed very well on individual tests. First of all, it had a startup time of 22.3 seconds, which is quick for a non-Ultrabook laptop; by comparison, the HP Envy Sleekbook 6z-1000 took twice as long (45.9 seconds) to start up. The Inspiron 15R 7520 also did well in our Web performance and office productivity tests, producing 13.5 frames per second in the former and achieving a score of 4218 in the latter.
The Inspiron 15R 7520's discrete AMD graphics card helped to boost its graphics performance. In our Crysis 2 graphics tests, the 7520 managed frame rates ranging from 12.7 frames per second (maximum quality settings, 1920-by-1080-pixel resolution) to 63.2 fps (low quality settings, 800-by-600-pixel resolution). While those are good scores for average all-purpose laptops, they're not quite the frame rates you need if you want to play a lot of graphics-intensive games. The Alienware M14x, for instance, carries an Nvidia GeForce GT 650M graphics card, and it achieved a rate of 94.7 fps on our low-quality, 800-by-600-pixel Crysis 2 test (the M14x does not have a full HD screen, and therefore we could not evaluate it on the maximum-quality Crysis 2 test).
One area in which the Inspiron 15R 7520 failed to perform well is battery life. In our battery-life tests, it was able to last for only 3 hours, 43 minutes—exactly 2 hours less than the average battery life of the last three laptops we've tested in the all-purpose category. And that isn't even taking into account the category leader, or the Acer Aspire TimelineUltra M5, which managed to survive a stunning 7 hours, 24 minutes on one charge of the battery.
At 7.4 pounds sans accessories, the Inspiron 15R 7520 doesn't win any awards for slimness or light weight. This 15.6-inch (diagonal) laptop measures 14.9 inches wide by 10 inches long, and is 1.4 inches thick, but its blocky, plastic design makes it look even thicker than that.
The Inspiron 15R 7520 has a solid plastic chassis with metal accents. The lid has a black aluminum panel with a subtle honeycomb pattern, a silver mirrored Dell logo in the center, and a silver plastic border. Although the aluminum panel adds an element of class to the machine, the plastic border keeps it looking cheap. The inside of the Inspiron is better looking, however: The matte screen is surrounded by a black plastic border with curved edges, and the keyboard deck has the same honeycomb-patterned black aluminum panel.
