Future Android versions will improve battery life by killing background services

I am skeptical when I hear about what Google is doing w.r.t. to Android, in particular I wonder if any of these people have actually used an android device.

My Nexus 7 tablet has a hard time just charging, turning on and off, and the people I know who have actual phones have continuous problems.

I remember Win 2k allegedly having "power management" on laptops, which mostly meant that my co-workers at the time had their laptops lock hard 4 times a day and have to remove the battery to reboot. Android is a much worse mess than anybody admits it is.
