Battery drains so fast

  • 772

I have an HP laptop. It is a 64 bit machine. But I have installed 32 bit Ubuntu 12.04 presently. My problem is, once the battery is fully charged and start using Ubuntu it gets drained completely within less than two hours. The interesting fact is that, I don't run any heavy tasks during this time. Watching a movie or surfing Internet causing such quick battery drain.

I have Windows also in my machine on which i get almost three and a half hours of battery backup. Can someone help me? Is this normal with Ubuntu? Or is it because of the installation of 32 bit OS on 64 bit machine?

12.04

  2. Since, your machine is of 64bit, it would be better to install a 64bit OS. I am not saying that a 32bit OS can not run in a 64bit machine rather if you install 64bit OS, there will be a lesser amount of battery consumption. Plus since you are using two OS s simultaneously, the drainage of battery would obviously be higher.
