Its not designed to misbehave, I just prefer it not running all the time.
Well, one thing everyone should know is that there's no need to worry about apps behaving oddly these days.
Both my parents' Android smartphones are loaded with apps and are used as actual smartphones (mostly phone calls, some texting, some Internet browsing, and some Facebook time, with a game or two in between), and even these phones manage to have 70% or more of the battery capacity remaining at the end of the day, despite Wi-Fi and GPS being turned on for the entire day.
Not worrying about apps running amok rings even more true in the world of Windows Phone and iOS, as multitasking is rather... strict.

In other news, my laptop's battery has 27.5% capacity loss.
Ouch! Time to bring it to a Toshiba service centre and get a replacement battery. You know it's bad news when your system is throwing up battery life warnings.
