>What does grate is is that I can’t even get a day’s charge out of it

Then you are doing something seriously wrong. My iPhone's batter lasts 3-4 days on a single charge. I use it for GPS and podcast/spotify consumption through out the day.

I don't know why everyone keeps yelling about smartphones and smartwatches not lasting even for a day. All I can think of is that they are playing games or using some constantly connecting social media app(s) through out the day.
