Does leaving the phone plugged into the wall really reduce battery cycle counts? Because, from what I'm reading, it looks like the phone will go from 90% to 100% (while displaying 100%) and do a whole bunch of 90-100% cycles (10% of a full charge cycle) if it's plugged in. There are, however, lots of posts saying that leaving your phone plugged in will reduce charge cycles. Does it? So in a way, plugging in doesn't reduce charge cycles at all, just keeps the battery at 90%+. Because it doesn't run off of the power source, it just does 90%-100% on battery and charges over and over, right? The only real way to reduce cycle count would be to like turn on Airplane mode, not use anything battery intensive, or ... just turn off your phone, lol.
