I don't charge my phone unless it is needed. Example, If when I go to sleep I am at 50%, I am not going to charge my phone. So if your phone drops only 15% to 85% when its bedtime, you charge anyway? That doesn't make sense.
Why doesn't it make sense? I want a fully charged phone every morning since I go to the gym and stream Sirius XM over 3G for one hour. Why wouldn't I charge it? My outlet is right next to my bed with a charger ready to hook in. NOT charging it doesn't make sense.
