2A chargers

There is a phone, samsung galaxy s3 gt-i9301i, one piece.
Charging, in my opinion, is a bit long, either off or on.

The charger is 1 amp, the cable is normal (all 5 pins are in place), the battery capacity is 2100 mAh - it charges for three hours, or even more.

Answer the question: will charging at 2 amperes such a battery burn, or is it okay?
