Perhaps you're not understanding what we mean by charging at night? We're not saying charging more than once a day, just that the time we choose to charge is while we sleep and as you put it we're not using the phone anyway.
The time of day that works best for you is the best time for you to charge your phone. Me personally, my phone isn't stationary long enough during the day to charge during the day. From 6am until ~10pm I'm on the move and my phone is about as attached to me as my hands and feet.
. I use between 4-6 hours os screen time daily because my phone is my communication device,pda, music player, etc.
