Windows 7 - 'monster' sucks netbook battery?

Recently, computer magazines and forums have been complaining that Windows 7 makes battery life significantly reduced on netbook models.

On August 24, LaptopMag - a notebook maker specializing in notebooks, announced on its blog a test of Windows 7 running on Toshiba netbooks. Accordingly, the battery life on this netbook has been reduced by 30% when using Windows 7 compared to using Windows XP earlier (6 hours 53 minutes on Windows 7 compared to 9 hours 24 minutes on Windows XP ).

Legit Reviews thinks the battery capacity difference on the Eee PC 1005HA between XP and Windows 7 is only about 2 to 8%. Last month, Tom Hardware - a computer hardware website also had similar complaints, claiming that the Acer Aspire One netbook using Windows 7 RC lost 2.5 hours of use. battery compared to using Windows XP Service Pack 3 (5h54 minutes compared to 8h28 minutes).

Complaints and claims that Windows 7 is like a 'monster' that goes 'sucking' batteries on a netbook or laptop is also expressed by many users on eeeuser.com forums (forum for users). Eee PC netbook from Asus) or AspireOneUser.com, MSIWind.net .

However, the views of hardware and software testers about battery life differences when netbooks running Windows XP and Windows 7 are still very different. At the end of July, in an analysis of Windows 7 RC and XP on the Eee PC 1005HA netbook, Legit Reviews website said the difference in netbook capacity between XP and Windows 7 is only about 2 to 8%.

Anyway, complaints still appear on the Internet a lot enough for people to question the availability of Windows 7 on netbooks. With today's highly mobile devices, battery capacity is still a factor of great concern and attention to users.

Many manufacturers have been working hard to improve the battery parts on their netbooks to meet the requirement that the device must operate a full working day with a single charge.

Earlier, Microsoft announced that Windows 7 will help make battery life on laptops about 11% higher than Windows Vista.

A Microsoft spokesperson declined to comment on recent reports and complaints, but released an article published on June 23, which instructed software developers. Device driver, hardware experts customize their link link for longer battery life on Windows 7.

Some hardware experts also voiced protection for Microsoft and Windows 7 when they thought that hardware drivers (hardware drivers) and their interoperability with the operating system played an important role in determining plan to use battery life on netbook or laptop models. For example, on Windows 7, the driver that controls the Wi-Fi chip does not work properly, making it impossible for users to turn off this mode, which leads to battery drain.

The same is true for the CPU and GPU coordinated control driver (graphics processing chip).

Jack Gold, an independent researcher, said it was too early to "accuse" Windows 7. " For the RC version, Microsoft certainly left a lot of bugs in the code of Windows 7 and everything still can be improved , "said Jack Gold.

The expert also urged hardware developers not to "recycle" their device's drivers from Windows Vista to run on Windows 7 but "start over".

However, this situation also made Microsoft anxious to recall the failure lesson of Windows Vista. One of the reasons that makes Vista "dead" is that after several months of the operating system's release, hardware manufacturers still do not have enough drivers for their devices.
