I plug mine in every night and it usually is the only time I plug in. If that day was particularly busy or I felt like playing a game, I might have to plug it in for a bit.
Interesting note. My first iPhone 6S's lower volume button ended up getting sticky to the press. I went to the Apple store and figured they would open it and fix it up but instead was surprised with a replacement device. Now, I wasn't a part of the whole "chipgate" thing so IDK what chip I had in the first phone.
But the replacement device had ATROCIOUS battery life. I'm talking two full charges a day. I'm talking 5% before 5:30 PM. I'm talking DEAD phone in the morning (no alarm) if I forgot to plug it in before sleeping with ~50% left. It was awful. I checked out the chip and sure enough it was Samsung.
And then a week later everything was fine. Battery life is just as I was used to. Back to the regular routine.
Its 2015/2016. I'm surprised there are still devices that required breaking in the battery. What I'm talking about is how old electronics like laptops etc were recommended or required to plug in to full charge before the first power on.
