I was just doing random stuff on my phone and went to click a button near the top right of the screen, and was mildly horrified to see "1%", so I immediately put it into the charger, where the phone promptly started showing "0%" for the next ~30 seconds. The phone never died.
Has this happened to any of you?
That's why I asked. I knew about the cycles but I'm not aware of it causing any additional wear. I thought maybe there were new findings recently. I'll have to go look myself, just to satisfy my curiosity.
