Although the battery life is good with my S7 it still gets down into the 10s-20s by dinner time with heavy use. So I am wondering if it is possible to over charge the battery? Back in the day of flip phones Verizon used to say if you charge the phone too much it kills the battery - is that still the case? I have a QI pad in my office, a QI pad in my car, if I just charge the phone off and on throughout the day and on the way to/from work is it going to end up having a negative affect on my overall battery life? Should I still let it get pretty low then charge back to 100% to keep it at the maximum capacity? Thanks!
