Can anyone explain why sometimes the fast charging notification doesn't come up?

[AC Question]

The phone is still charging regardless if it gives the fast charging notification or not but I am assuming that it is not in fast charging mode when it doesn't say it is...any ideas why it randomly stops?

Welcome to Android Central! Which phone are you talking about?

Qualcom Quich Charge 2.0 only quick charges to 60%. After that it reverts to a normal charge. So if the battery is at 60% or more you won't get the notification.
