I had a 6+ which a sold a couple weeks back. First of all, I love this phone but if you're coming from an iPhone there are things to consider:
1)Android allows apps to have free reign for some reason even if notifications are off. I use the app Doze and Greenify to help with it. You'll have worse idle drain on android.
2)Google seems to think it can keep its services running regardless of the user's wishes. It is a major problem when Google music wakes up my phone when it is idle and wasn't even used that day. I do not understand why Google does this. If you use the wakelock detector workaround you'll see Google allowing it's apps free reign of your phone. It is ridiculous. Plain and simple.
3)with those last points said, prepare to do some work to get the phone working to your liking. Be prepared to disable bloat, Google Apps and install battery tools. Be better than those people who come in here and say their battery is terrible and basically throw a temper tantrum and refuse to do anything to get it to a manageable level.
Do not say that "you shouldn't have to disable everything Yada yada" The point is, is that this is not an iphone. An iPhone doesn't have the features that these people complain about having to turn off. Apps do not automatically behave; app makers think their app is the only app you'll have on your phone. Think having 20+ ios Facebook apps on your phone. This is an issue that I hope android addresses but it is maneagable. Do not trust Google services to behave.
Good luck and I hope you find the phone that works best for you. The Note 5 is a powerhouse and I love it but it requires work. Be warned.
