Windows 10 and battery life

[briangw]

Hi,

 

I understand this is a TP and no way is it finished but I wanted to check with others about battery life in Windows 10. In both my gaming laptop (with a hybrid Intel HD/GeForce 650M) and my Surface Pro 3, just using the HD cards in both, it doesn't last long, even when sleeping/hibernating. My SP3 was fully charged before I went to bed and was sleeping/hibernating overnight. I woke up this morning and it was dead. So, I was just wondering if others were having the same issues with laptops. If so, I'm happy to know that MS would know and I will just leave this on a desktop for now.

 

Thanks,

Brian

A bigger driver of battery life - in any OS - is what you are doing.  If stability and performance increase in an OS - beta or otherwise - compared to the OS it replaced, it WILL have a negative impact on battery life, simply due to you taxing the hardware to a greater degree.  (That is certainly the case with "Baby Pavilion" - the smaller of my two legacy notebooks now running 10049.  The OS it originally shipped with - 7 Home Premium - didn't even fully leverage the capabilities of the notebook - the issue there WAS the operating system itself, as 7 didn't include Hyper-V hosting support.  In other words, darn RIGHT my battery life is getting taxed - greater application load = a greater taxing of my battery.  That will also mean that I will be saving my compiles to when I am on AC power, as opposed to battery power.  However, with the previous OS (7), using the notebook for development wasn't even a reasonable option - due to a feature support lack in the OS itself.).

Battery life for me was pretty bad. I always just attributed it to the many debug and logging processes that are being run.

That's just it. I was doing nothing on both my laptop and SP3. In both cases, my laptop was just sleeping and the SP3 was in hibernation. If I was doing anything, it would have been Internet browsing or working in MS Word.

With 10240 on my Surface Pro 3, I feel like I'm getting much more battery life - this might be placebo, though for two days now it's saying in the battery usage html output that it could have achieved 8+ hours, as opposed to 4 previously.
