Is charging your phone all day, really that bad?

What the science says

Charging your battery causes its performance to degrade over time, no matter how you do it. Smartphones are powered by lithium-ion batteries, which work by moving charge carriers (in this case, lithium ions) from one electrode to another. The ions move in one direction when charging and the other when discharging.

Well then, that debunks the theory that you should let your phone discharge 100% or close to it, before charging it. I was hoping the article would explain why certain activities on my phone, discharge the battery more so than others? For example, if I'm listening to songs on Youtube, the battery discharges faster than say if I'm on a 20 minute phone call.
