I have an old laptop(5+ years) running fedora 18, It has core2duo processor and I have recently replaced its battery.
With Windows battery life is about 3-3.5 hrs but with fedora 18 running gnome-shell it is hardly 2 hrs.
I will be getting a new laptop with AMD A10 processor, Richland architecture in about a week.
I got my Z3 at the beginning of this week, and I have to say it is an amazing phone in a lot of areas including the battery life. I know there is another thread for battery life results from various users, but I want to create a dedicated thread for my personal experiments showing results of battery life and mainly its recharging capabilities on various chargers, wires, etc. that I have on hand.
