I see both sides. I agree with you, I'm the same in that I plan very accordingly and would probably go crazy if I was in a "Hotel Tonight" situation. However, I like to know that if I was ever (somehow) in a "Hotel Tonight" situation, the app is there and ready to use for my convenience.
To add to your battery life point, I wish there was more exposure to how apps eat battery life on your iPhone. It would be nice if Apple somehow exposed that to the user to see where and how apps are eating up your battery life. I know there is some apps out there that sort of tell you, but no where near the level of details I think Apple should expose.
I'm the exact opposite. The anxiety I get from needing to stick to a regiment/ itinerary destroys me. One of my favorite parts of travelling (to cities like LA/ NY where Hotel Tonight is relevant) is hopping off a plane, heading straight to a meeting, and figuring out where to sleep on the fly.
There's definitely other kinds of people out there!
I feel like it's worth pointing out that Android makes this kind of information easy to get to - BetterBatteryStats[1] and GSam Battery Monitor[2] are both amazing in tracking down and fixing power leaks.
I think that this is sort of the core of the Android vs iOS difference; iOS says "don't worry about it, trust us to get it right", and Android says "here's enough rope to hang yourself with, but you can also use it to climb out of that pit if you want".
