dayachan, from your description it sounds like a bad battery. Start with that. If it should continue to do this, check the charging port. Anything after that will be on the board. Could be a bad power management IC but that will involve special tools and skills to replace.

This is a much better answer than it appears to be. A battery that will only accept say 35% of it's original capacity, will recharge very quickly to that full 35% because it not charging as much as when the capacity was much higher.
