Yeah battery management should be simple here but it isn't. On the iPhone I left everything on all day and typically made it through a day with even heavy use. Back to Android I have to do stuff like turn on and off certain features and I'm still trying to figure out what apps and process running in the background are keeping my phone awake even with the screen off.
It's like the difference between eating at an all you can eat buffet vs going to a high scale restaurant. Google's philosophy is here's the components do whatever you want with them and Apple's is this is what we serve and how we serve it.
