What I mean is, do you spend much time going in and killing apps that you've recently used? I was with iPhone from the very start but in the last year or so I've been pretty fully dedicated with Android. I always made it a point to back out of apps so they'd close down when I was done using them.
I know that both iOS and Android do a pretty good job about killing processes as needed but I tried to manage it myself if I can. I never used things like Task Killers but I'd do what I could on my end.
But as it stands, I'm getting tired of worrying about that crap, lol. I just got my iPad 4th Gen and wondered if I should be perfectly fine with ZERO concern about all the apps running in the multitasking bar.
Nope. On my ipad, I don't run a GPS app so I hardly ever close apps. On the iPhone, I do close GPS apps, such as waze especially when I quit the app before reaching my destination. Very much impressed with task management in iOS. I used android 4.0 and I was constantly closing apps since my battery was so bad.
