There's been a lot of debate, mostly influenced by AMD, about how Bapco's MobileMark

2007 unjustly represents battery life on laptops.

AMD's argument is that the industry should adopt a similar battery reporting style

as cell phones and digital cameras, where there's an active and a standby score. The

company has a valid gripe,Acer aspire 3690 battery but even so, MobileMark is still the best test out there.
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, 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.

AMD is basically saying that MobileMark 2007 tests the equivalent of the standby

time in cell phones. That's a little unfair. Apple a1175 battery 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.

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 videos—tasks that eat up 50 percent to

80 percent of the average CPU, and subsequently 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. Toshiba pa3615u-1brm battery ,Toshiba pa3672u-1brs battery 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.

Sure, Bapco should to address this lack of an active component by introducing

applications like iTunes, Windows Media Player, and looping Web pages filled with

JavaScript and embedded videos. But that doesn't mean the current test is invalid.
