Full charge notification

[Android Question]

Hello. I am using Samsung Galaxy Tab 3 8.0
Usually when I charged my tablet, it always notify me that the tab was fully charged. However, lately the notification did not appear even the battery icon shows 100%.

Leave it charging a little past the 100% point. The battery percentage indicator is indicating one thing, the "disconnect the charger" notice is indicating a different thing. The battery charges to what appears to be 100%, then drops a little, then charges back to 100%, at which time the "disconnect" notice comes on. It's the way the chemistry of the battery works.
