Anecdotally, I appear to get better battery life with Windows (and some vendor-specific additions) than with Ubuntu on my laptop.
It's great to hear this is an active area of development, as it's probably the biggest remaining factor in me choosing host OS.
- pavelkaroukin 15y agoIt is quite true. A lot of hardware today require drivers (ah.. I remember days I hated software modems 'cos without drivers these were useless, and now this is normal). And most drivers are proprietary. And on top of it - often hardware is being customized by OEMs requiring even more spcialized drivers.. And of course, nobody bother with doing drivers for Linux... This is a case with my new Dell Precision M6600. It have on-chip GPU and discrete GPU. I still trying to find a way to switch to integrated GPU. And this one of the areas Ubuntu 12.04 should fix (well. To be exact, not Ubuntu, but kernel included into this distribution). Just from witching from external GPU to internal GPU I expect to bump battery-time to ~6 hours from current 3 hours.
- ralphc 15y agoI have the same anecdotal battery life on my i7 Asus, so I ran a semi-anecdotal experiment. I'd charge the battery, connect to wifi, unplug the battery, do nothing for 10 minutes, then see what the OS reports as the time left on the battery. Windows 7, pre-installed on the machine - 4 hours, 30 minutes Ubuntu 11.10, dual-booted on the hard drive - 1 hour, 48 minutes Ubuntu 12.04 alpha, booted off of a USB stick - 1 hour, 38 minutes Hopefully 12.04 will get better.
