Problem charging Samsung Galaxy J5

[Hinatule]

So as instructed after getting the phone and having to charge it for the first time,I read that a few hours until it's 100% is enough. I did that. Charged it right before bed,turned off all programs,wifi,everything and yet in the morning it had 68%. Does this mean the battery itself is damaged or I somehow charged it wrongly,like not enough? Please help.
