Vista Battery Life Myth

I do not know from where it's coming the Idea of Vista sucking 30 minutes of Battery Life. When I had Vista in my Q1 without any power managment installed (from Samsung) I was getting a battery life of around 2 hours. When I had it with XP, I was getting around 2 hours and 15 minutes. Now that I installed the power managment profile that came with the Q1p Vista preinstalled I'm getting 2 hours and 10 minutes. And I have not touched anything, I just installed all Vista Drivers that came with the Q1p Vista Preinstalled. 30 minutes represent 21% of less battery life and I can tell you for sure that I have not seen that neither in my Q1 or my eo v7110. You will get less battery life but is not 20%, it's not 10% and it's not even 5%. If you ask me, if that's the price to pay for having a handwriting recognition that is a lot, and when I say a lot I mean like 5 times better than what you have experienced so far in XP, then I'll say that I'm glad to pay that price.

And I hope my dear readers that by know you know me enough to know that when I want to check something I spent my time doing my homework. I do not go by other people tests, I run my own ones.

I believe that the myth of Vista using more battery life came from the first people that installed it in their machine and did not configure properly the Power profiles. And a proof of that is that Samsung released it own power profile which is different than the Maximum Battery Life Profile of Vista.

There are people that installed Vista in a Q1 before me. But probably I'm the only one that installed and never went back to XP, I kept using Vista fighting with all drivers problems until I got it all right (even better than Samsung did because I got the real HID Driver from the maker of the Touch Screen :-))


  1. I'm never sure whether to reply here or at OrigamiProject. See my reply there:


  2. I Just answered there but I'll say it here again.

    there is a big difference between the results to saw using Microsoft Power Saving Profile and the ones I'm getting since I'm using Samsung's Power Saving Profile.

  3. I was not clear. My last test DID use the 'Samsung Power Saving Profile'. And I saw the same results.

  4. Lets put it in a different way. Everything is a give and take. The advantages of using Vista are for me more than a few minutes less of battery life.

    In my case it's not that big difference in minutes. In your case, John, I would consider to buy a extended battery.

  5. I don't think the complaint is between xp and vista. I have a macbook where I run mac os 10.4 and vista, and whenever I'm in macOS, the full battery goes for 4-5 hours. When I reboot and log into vista, it is a little over 2 hours.

  6. It's not a myth. I reinstalled XP on my gateway tablet because it gives me about 4:20 battery life, as opposed to Vista's 2:10. On Vista my processor would also hit 75 degrees C on battery when the system was "idle". On XP it hovers around 52 degrees C.

  7. Just by optimizing a little bit Vista you are going to get about the same battery. Another question would be, did you have install SP1? SP1 should have taken care of your problem.
