I've benn using win7 pro 64bit since december and no problem at all with my bateries in fact both my batteries last longer compare to vista home 64bit.
Tha bat my HP pavlion dv5 1100 came with now lasts 1.5 hour (25 minutes more) and the extented lasts 4 hours (55 minutes more). Never had a problem with win7 BECAUSE I bought this laptop when it came out and the battery was brand new (HP that year made new bateries for the new series).

So since they said that trust them your batteries are alomost dead or dead.
When i bought my laptop I installed ubuntu 64bit aside of vista home premium 64bit. Ubuntu check the same thing in batteries for years now (my battery was in 80% according to Ubuntu when i bought it).

If you think win7 killed your battery install ubuntu (it's free) and compare the result if you see it below 40% then win7 is right your battery sucks!!!
 
"Microsoft has said that the battery problems currently plaguing a number of Windows 7 users are not caused by the operating system."
Really, OK I believe you and I also believe you when you say there is no built in back doors for the FEDS too, (hand over mouth) bullshit.
 
[citation][nom]psycho sykes[/nom]As I said (but I was down-voted and no one believed me) I already tried that.. I tried Vista and Kubuntu 10.04 before and after Installing Win7I tried them before because Win Vista was my OS and I got Kubuntu's CD as a gift so tried it.. Then I tried both after the warning started showing up and my battery was really dead..It died just 2 weeks after installing Win7..[/citation]
Post Hoc Ergo Propter Hoc
Latin, "after it therefore because of it"
If your battery died after installing Win 7 people will always assume it caused it, people never look at wether it was broke to begin with.
 
I've noticed a slight deterioration since moving to Windows 7. Instead of the usual 2 hours and 10 minutes my notebook only lasts about 1 hour and 50 minutes or so till it shuts down, but I think it is due to the extra features such as animated backgrounds and such.
 
[citation][nom]Pyroflea[/nom]Want to explain to me how this software is destroying a power supply? (Battery)[/citation]

One of the features of Windows 7 was "Extended batery life" (Which I believe was recently proven false).

I guess if it can extend its life, it could also shorten it.

Note that I'm on neither sides as I don't use Win7. Just my two cents. :)
 
For those on XP/Vista there are tools that can tell you the remaining life of the battery (not just the charge). I personally use Lavalys Everest. After a year my laptop battery lost 15% of it's life indicating that the battery can only hold 85% of the power it used to when it was new.
 
I've been using Win7 since sept and never had a problem until recently. First time I saw the message it reported that my battery would only last 1 hour fully charged, if I replaced it, it would go for 1.5 hours. Other times it says my battery will last 1.5 hours fully charged and a new one would give me 2 hours. It changes every time I click on it. When I first installed Win7 I would get about 3 hours on a full charge.

Whether my battery is bad or good I dont care, but why would I replace it for 30 mins more??? Honestly this seems like a bug and I would guess it has to do with a recent update or something as I never encountered this for the first 3-4 months or so of using the OS.
 
Micro$uxx as usual: "it's a feature, not a bug".
If m$ did "innovate" again, believing to be smarter (it always does) than the HW manufacturers, and screwed the battery management algorithms, it's not at all improbable to kill LiIons... they're quite sensitive to abuse, especially over(dis)charging.
"To the very best of the collective ecosystem knowledge": is that the new syntagma for wintarded m$ fankiddies, who'll believe and parrot any $hit their god tells them?
 
Since Microsoft does not make the PC hardware, it is ultimately the responsibility of the hardware vendor to release firmware updates and to answer for OS compatibility issues. Did any of the persons complaining even check with the company who made their laptop? If most people look at the support page for their hardware they will find that there has been a new update around or after Oct 2009. Look for BIOS updates, ask your hardware vendor if your laptop is even compatible with Windows 7.

Oh and (shhh!) this same battery issue happened to my G4-Powerbook when upgrading from OSX 10.2 to OSX 10.4, almost no battery run-time right after upgrading the OS. The Apple support rep told me my hardware was incompatible with the new OS and advised to go buy a new mac to unlock the magic new features of OSX 10.4. The Powerbook magically disappeared soon after.

If you take a broader view, It is quite impressive that windows can be compatible with tens of thousands of different pieces of hardware+software. This is the true strength of the Windows OS.
Unlike my mac's OS that is only compatible with maybe a hand full of Apple-only PC's and only the select few add-on devices+software that apple has chosen. The tight hardware control is Apple's strength.

I own:
Linux home built media server, Win7-32 Shuttle XPC (wife's rig), Win7-64 Shuttle XPC (HTPC), Hackintosh running intel quad in a recycled G3 desktop case (had to put the bought OSX10.4 to use), Win7-64 dell Studio XPS 13" modded w/Q9100 28w quad cpu (my rig).
My work gave me a macbook-pro, after the "sexy-new" buzz wore off, it's kinda a "vanilla is the only flavor" experience.

Funny, it should be the other way around, micro$uxx to respect established standards, and not make up their own (wishful thinking), so the whole world has to patch things, to fix m$'s blunders, and "innovations".
[citation][nom]noneedformonkeys[/nom]Odd that this battery issue is not being reported by persons who purchased a new laptop with Windows 7 already installed.[/citation]
Reminds me of a USB "problem" a decade ago, when windblow$ 2k "lemoned" the interface... Of course, the MB mfg was forced to issue a BIOS "fix", which never worked. Every other OS was happy with the original BIOS, even older micro$uxx issued ones...
 
I don't agree to Microsoft's explanation. My laptop Acer Extensa came with Vista pre-installed. The batter lasted for 2h30'. Right after windows 7 installed, I noticed that the battery life dropped to 55 minutes. It is now worst. Battery now lasts only 45 minutes. This is not acceptable. I then switched back to Vista and the problem stays. Does any one know how to fix this?
 
Most of the people saying that Windows 7 isn't killing batteries don't have a clue of what they are talking about. I installed Windows 7 in several laptops where the average battery duration was known. 2/3 of those laptops worked just fine and the average span maintained with Win 7, the other 1/3 of them had a 60% span loss in under a week and even after formatting and installing other operating systems the batteries span was still under the average levels that they were one week before. It's so much easier to have a God complex and assuming that people talk out of their asses and don't really know about the subject. There is one thing called first-hand experience that you may or may not be familiar with and that's irrefutable. Google the subject and see how many users of diferent laptop brands have dead or semi-dead batteries for using Win 7, Sony, Asus, Toshiba, Dell... you'll even find MacBooks users having that problem. If a battery duration is about 1h30min using Windows XP and after a week on Win7 it's duration decreases to about 30min that doesn't prove anything but if you reformat and come back to the Win XP and the duration keeps on 30min then you have a bit of proof, amount that to the same outcome in other laptops and you get to the conclusion that Microsoft Windows 7 is indeed damaging batteries under specific hardware/firmware circumstances. Why it happens is anyone's guess, but somehow Windows 7 messess with the batteries consumption and charging cycles in a way that cripples them. You cannot prove everyone wrong on this matter, obviously. I wouldn't risk it if I were you, get rid of Windows 7 if you notice substancial battery loss, one way would be to have a dual boot with another system and get it clocked, you'll notice the diference after a while.
 
I've seen similar things here.
We bought two identical Dell XPS laptops around 3 years ago with Vista.
One of them was upgraded to Windows 7 within weeks of 7 coming out, at which point the laptop was about 1 year old. Within weeks the battery became unusable.

The Vista machine did not have any issues up until a couple of months ago when it was upgraded to 7.
Within a month the battery became unusable.

I don't understand how as the battery should be untouchable by the OS but 7 definitely damages them.
 
Thank you for making that point.
A lot of people comment on this subject solely based on their humongous expertise with rechargeable batteries, what they lack is a personal experience, obviously. They account for natural decay in performance of the different types of batteries (NiCad, NiMH, Li-ion, Li-polymer) but do not account for the possibility of the OS to hijack the charging process and interfere with it's normal charging cycles, possibly leading to the substantial performance drop. Even if I'm not sure how it is technically happening, it is happening nonetheless.
