Testing Laptop Battery Tests
AMD’s argument is that the industry should adopt a similarlaptop battery reporting style as cell phones and digital cameras, where there’s an active and a standby score. The company has a valid gripe, but even so, MobileMark is still the best test out there.
AMD is basically saying that MobileMark 2007 tests the equivalent of the standby time in cell phones. That’s a little unfair. Granted, the laptop is using roughly 10 percent of the system resources and there are idle times during the test that brings CPU utilization down to nil. But while the test is made up of various business applications and emulates a day in the life of a business professional, the usage scenarios eat up as much battery life as surfing on the Internet all day.
Bear in mind, MobileMark is an industry benchmark test created by Bapco, a consortium that’s headed and funded by Intel. Some of the biggest PC names also sit on this panel, including HP and Dell battery, and they provide tons of input as to which applications should be included in the benchmark test. Even though AMD is part of this consortium, its input is probably underappreciated, since the majority of processors that run on these laptops are made by Intel.
Thing is, that is exactly what most people do with their laptops. They check their Facebook accounts, compose e-mail, write blog posts, and chat on IM. Although some users may be listening to music or watching videostasks that eat up 50 percent to 80 percent of the average CPU, and subsequentlylaptop battery life, most people don’t use all of the CPU’s power for extended periods of time.
AMD is proposing an active test, in which a gaming benchmark test like 3DMark06 or an HD video would be looped until the battery runs out. Thing is, almost no one does that.
Few people play games for three or fours hours straight on a laptop, and if they do they connect to an AC adapter. After all, CPU speeds would typically throttle down and impact gaming performance. Looping an HD video is more realistic because users can get immersed in a movie or a video. But again, this doesn’t represent the typical day in the life of a user.
We leave wireless radios on, because unless you’re on an airplane, a typical user would want to leave WiFi on.
Put simply, MobileMark 2007 is the best test out there. It uses commonly used applications, such as Adobe products, Apple’s Quicktime, and Macromedia’s Flash. AMD suggests giving two sets oflaptop battery scores, a low and a high rating, but this is no better than saying this laptop gives you two to five hours of battery life. We need a definitive score that addresses active and standby times because there are just way too many battery workload scenarios out there. Right now, there is no other recognized standard test available to reviewers.
Perhaps most importantly, MobileMark allows us to test consistently. It offers a fair comparison of battery life across the swath of laptops on the market, at least for the scenario BapCo has created. Of course it could use improvement, but right now MobileMark is the fairest battery test on the market.
Laptop Battery Tests
Laptop batteries have a relatively short service life and are really expensive to replace. There is almost no remedy to restore the capacity of the laptop battery one it is worn out. Though the actual life of a laptop battery depends on the usage habit of the laptop computer, most of the laptop users often complain that their laptop batteries no longer hold the charge and that they wanted a new one. Testing laptop battery life will help you in determining the expected life of the battery, so that you can avoid unexpected battery problem while using your laptop. You can also estimate the date for ordering a new battery. Some of the factors such as CPU utilization and screen brightness affect a laptop battery life. The criteria that affect the battery life can be used to measure battery life of all laptops. There are many free services available on Internet and from software developers that aid in testing the status of laptop battery. Some software is available to test the laptop batteries. Some software can also estimate remaining life of the laptop battery. Laptop battery performance tests are designed to measure the expected battery life of a laptop. A battery analyzer is recommended if you need a full battery service. Gnome Power Manager is a power management tool which can display detailed battery information of your laptop. The tool even detects and explains the problems which are responsible for causing poor performance of the battery. It also gives the details of the quantity of battery’s capacity degraded. It gives information about the original capacity of the battery in your laptop. An interesting feature of this tool is that it can give you information on the amount of power consumed by your computer at the moment. The Cadex C7400 is a programmable battery analyzer that is capable of quick testing, charging, priming and reconditioning of the different types of laptop batteries. Lithium, nickel and lead-based laptop batteries can be quickly and easily tested using the programmable Cadex 7400 services. The Cadex C7400 analyzer uses a quick test program to measure the laptop battery health in about 3 minutes, independent of charge. The Cadex C7400 analyzer uses OhmTest program to measure the internal battery resistance. Battery Eater is a testing tool meant to disclose the potential of a laptop battery pack. Battery Eater is a small program which can measure the laptop battery life efficiently. This software tool is used to measure the minimum operation time of a laptop under maximum workload. It heavily loads CPU, HDD, RAM, and video card while performing the test. This software tool can work efficiently in the Idle and Reader’s Test mode when all power-saving options are fully enabled. This software is cost-free, and is easy and simple to use. This software uses a flexible testing scheme that uses three test modes. The software keeps track of the laptop battery performance. The additional feature of this program is that it can show system information such as battery name, battery type and battery manufacturer, AC status, and CPU, RAM and display information. Using this program, you can test the battery life of both old and new laptops. CNET Labs’ test named as Video playback battery drain test is specially designed to determine a laptop’s expected battery life. oz zeldom is an expert author, who is presently working on the site Power Tool battery,Professional Camcorder battery For more information aboutTwo Way Radio battery .
