1. I've switched from my old beater iphone SE and the battery life has been great. Lasts 1-3 days depending on usage.
2. Agreed, the lack of bezels while pretty aren't necessary and makes it difficult to use with a single hand (the primary selling point)
3. Linked to the bezels, they probably didn't have enough room due to extending the screen to the top.
4. Sadly, that's just any new iphones
5. Partially disagree, it's wonderful that you don't have to hunt around to make sure it's connected and charging. The downside is the charger itself lifts up with the phone. Again this is more of what Apple imagines the future to be for all its phones.
I really like it as an upgrade from an iPhone SE. The primary complaint is the extra size wasn't needed and takes away from the primary selling point of compactness that you mentioned.
