Yes it's off but I'm on 4g and no power saving modes on.
Doze is working 100% perfectly on my phone
Android is like Windows, it gives you the freedom you want, but you have to realize that that means the user experience will differ.
iOS forces the system and apps to behave a certain way. Great for battery life and consistency, bad for multitasking. For example, you might get your music app or running app force closing on you, mid run, due to the nature of iOS multitasking. This won't happen on android.
Doze is great and helps with this, and Android N takes it a step further. But its dependent on what happens you are allowing to run in the background (ESPN, weather apps, etc can wake the phone constantly). What location mode are you using? Are you using google now? Are you allowing location history? Etc. These are things that allow Android to do some pretty cool things, that iOS can't. They can have impacts on your battery life. Also rebooting the phone, etc can help.
I found that my galaxy s7e battery was only decent for the first week. Now, about 11 days later, its great. I also stopped worrying about it, honestly. I stopped worrying about standby time, etc. All I know is it can make it all day easily, and a few days back, when I slept over at work, it made it all day/night, and to midday the next day, at which point I placed it on the charger with time to spare. I use location services, google now, etc.
This isn't directed at anyone in particular, so don't take offense. What is the point of leaving it off the charger at night, and monitoring the percentage? Why worry if it dropped 5% instead of 2%? Why even worry if it dropped 4% in an hour? This kind of obsessing ruins the experience. I highly recommend just using the device for a week in your usual routine, and account for the first few days being abnormal battery wise (system settling in, you using it too much). Then see if it gets you through the day. If it doesn't, then maybe move to a different phone? Also, don't forget the convenience of turbo charging. I had a heavy day a few days back, when I was using the phone with the screen on for about 4 hours straight. I plugged the phone into the turbo charger in my car for my 10 minute back and forth drive for lunch, and just like that I was over 80% battery again.
