Battery questions

[Bierklak]

Is it normal that my phone says its fully charged after 1-2 hours?
I have it only for 3 days now. Should i keep loading or disconnect as soon its 100%?

Are you charging with the wall adapter or the computer?
How depleted was the battery before you started charging?
You can leave it plugged in after it hits 100%...no worries
