Updated: Windows 7 can Ruin your Laptop’s Battery Life

Windows 7 is undeniably one of the best operating systems Microsoft had released. It gained a good response from people which tremendously resulted to the higher sales of the said OS. Despite its success, there are still some technical issues or problems which constantly bangs it. One of which is the issue regarding Windows 7 can potentially ruin notebook batteries. Below is an article from ComputerWorld detailing the said allegation:

Computerworld – Microsoft said Tuesday it is looking into battery problems apparently affecting Windows 7 notebooks.
Users have complained of battery issues — including premature warnings that the power is exhausted, as well as more dire demands to replace the battery — for months, long before Windows 7 went final.
Microsoft claimed that the problem was in the Windows 7 tool that decided when the battery had been drained, or was unable to hold a charge. “We are investigating this issue in conjunction with our hardware partners, which appears to be related to system firmware (BIOS),” a Microsoft spokeswoman said today, referring to the firmware that boots the PC and initializes the hardware components. “The warning received in Windows 7 uses firmware information to determine if battery replacement is needed.”

A very long thread on Microsoft’s support site dedicated to Windows 7 battery problems kicked off in early June 2009, and remains active; more than a dozen new messages were posted on Tuesday, for example.
While some users on that thread agree with Microsoft that the warnings are spurious, others believe that the new operating system has permanently crippled their batteries.
“I have tried charging the battery while the computer is off or in another OS, and it does not work,” said someone identified as “DanLee81” today. “It will charge for a few minutes, then stop. The battery will say it’s full when it actually only has a few minutes of charge, and when you take out the A/C, it will either last for a few minutes, or completely shut off your laptop. This behavior happens in all [OSes] after Windows 7 damages the battery, not just within Windows 7.”
Others reported that their batteries underperformed, even after they abandoned Windows 7 and returned their notebooks to running Windows XP or Vista, or switched to Linux. “Rolling back does not work either,” said “Dreklia” in another message on Tuesday. “I feel rip[ped] off!”
In some cases, Windows 7 claimed that brand new notebooks were unable to hold a charge. “Until yesterday it used [to] state that I had 7 hours battery life after a full charge; today after a full charge, it states that I have 4 hours left,” said “tigger1962” of a three-week-old Toshiba Satellite T110. “I’ve only had it on now 15 minutes and my charge has now gone down to 2 hours 24 minutes.”
Users reported a wide variety of affected makes and models, including laptops from Acer, Dell, Hewlett-Packard, Samsung, Sony and Toshiba.
Laptop owners are not the only ones who have noticed battery irregularities in Windows 7. Last summer, reviewers for several publications and sites said that Windows 7 slashed battery life by almost a third when compared to XP. That ran counter to Microsoft’s promise that Windows 7 would actually increase battery endurance.
Microsoft said it was looking for a common cause to the battery complaints. “We are working with our partners to determine the root cause and will update the [support] forum with information and guidance as it becomes available,” the spokeswoman said.

I, too, experienced a drastic change in my laptop’s battery life. Since I switched to Windows 7,  I noticed that my battery life become shorter and shorter as time passes. My Compaq CQ20 laptop is still new (still less than a year from the date of purchase) however I was shocked about the early death of my batteries. At first, I thought it was caused by undercharging and overcharging (though such were really proven to deteriorate battery life) but now, I’m having thoughts that such activities were not the only reason for the death of my batteries. Maybe it’s because of the flaws of the operating system itself (though I’m not really sure about it). :)
So what do you think?

UPDATE: After extensive research, Steven Sinofsky has now explained on the Engineering 7 blog that the fault is not with Windows 7 – it really, really is your battery. Read his post here.

    The easiest way to give your battery an early death is to damage it. And the two most common causes of damage are from overheating and overloading. Here’s how you prevent overheating:

    1. Use a cooling pad when using a notebook computer on your lap.
    2. Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up.
    3. Clean your desk. It sounds strange, but if you have a dusty, dirty desk, that dust will get into the vents and clog the cooling fan.
    4. Never store your laptop in a place where the air temperature exceeds 80 degrees Fahrenheit, such as a hot car or an outdoor patio.

    Making sure that your computer is completely turned off and not connected to a power supply before removing the laptop battery is the easiest way to ensure that you will not encounter any problems. It is also a good idea to use a soft cloth that has been slightly moistened with rubbing alcohol to clean the contacts in the computer before installing your new battery.

    If your laptop or desktop is running XP you could face hardware & software problems plus slow performance but if it’s Vista it will be less but speed will stay the same or slightly increase. No matter it will most likely not be what you hoped. Been playing with Win7 Beta, RC & RTM on two 1 to 2 yr old pcs and don’t recommend upgrading maybe dual boot. If you buy new it will be all good. XP still does everything most need to do. If you want to improve your XP PC performance just reformat.
