3hrs 15 minutes means it is charging the phone at a rate of approximately 600ma/hr (1875mah battery /600 mah charge rate = 3.13 hrs) which is exactly as it should be. Phone will not charge at more than 600-700mah no matter what the charger outputs so you have "power to spare" (but not power to use). So it is perfecly fine. You could use a 100AMP charger if you wanted since the phone will only "take" what it was designed to take. Charge rate is current limited by the chipset in the phone + the kernel for protection. If it were using the full 2amps it would fully charge from ZERO to FULL in around 50 minutes then probably explode.
