Ah yes, the myths of over charging damages. I've done it with every phone I've ever owned since the 90's. Never once replaced a battery or phone due to charging damage.
Tethered to a cord. I'm in the car, not using it much anyway. At work, I work with computers, sitting at my desk all day, it sits on the desk with me. At home, I'm sitting on the deck, watching TV, reading, or sleeping, the cord is 6' long, not in the way at all.
There is no reason to see how long my battery can last when I'm usually near an outlet.
I'd rather charge it whenever I want rather than turn off features, or not use the device for fear of the battery not lasting all week.
I use my phone more than I use my laptop, of course I'm going to keep it charged when I can.
