I'm not saying this to start a war, but I don't use an iPhone. I use an Android phone. I have found the Facebook Lite app on Android to use virtually no battery when idle. I know that this app was pretty much designed for low power phones. It's odd that on the one hand, they are thinking about low powered phones and using less data while on the other hand, as with iOS, they aren't.
