It goes for other phones as well. I ditched the app a while back as they kept trying to push separate apps for chat and such and generally just because I don't read Facebook that often. Switched over to a third party app called "Tinfoil for Facebook" which essentially just puts the mobile site in a sandboxed and somewhat optimized wrapper for easy mobile browsing. Battery improved as you'd expect by getting rid of one program that does a decent amount of stuff in the background. Nothing massive but it did make a difference. That said, I feel like disabling a lot of things would improve battery life but depending on the apps in question, battery life may not matter much if you can't use the app. It's more an overarching effort I've made to only install dedicated apps for things that I really use enough to need a dedicated app. Since I only check Facebook 2 or 3 times during a typical week it didn't seem to be very important for me to keep their app(s). I can still check it out every so often when I'm bored and want to see what people are up to but I don't have yet another background app taking up resources or battery capacity.
