I am using Linux Mint Cinnamon on my Lenovo Ideapad 151 since past 6-months. I have noted that since I installed Mint on my system its battery run out time has decreased. Initially I thought it was because my battery was getting older but the other day I read that it was a known problem with Mint. Someone was saying that his battery was giving 5-hrs on Windows but only 2-hrs on Mint. So is it really a problem with Mint? What others have to say about this?
