Battery Charged but not 100%

my galaxy s2, while plugged in to charger, says CHARGED.

but when i remove the charger, it becomes 97%.

does this happens to you?

It could be the battery is getting weak and losing some capacity.

I once heard somewhere it's normal. but it is possible that the battery is getting weaker, especially if you had the device for, say, a year or so.
The advantage of the Galaxy phones is that you can replace your battery easily so if you choose to do that, I recommend Anker batteries. They have one for the S2 and it has a higher capacity than the original battery. I ordered one for my old S1 it and was perfect.

It's normal to see it go right to 99%, but any lower is making me think weak battery.

the phone is with me for 2 months only.

Are you unplugging it right after it says it's charged? If so, try leaving it plugged in longer and see what happens. I know as the batteries get close to full voltage, they still need a "saturation", for lack of a better term, to reach full mAh capacity.
