As noted on Apple’s iPhone 4S specs page, the new handset offers Bluetooth 4.0 support. In addition, although Apple touted it’s improved battery life when talking over 3G, the device’s standby life seems to have taken a considerable 33% drop, from 300 hours on the iPhone 4 to 200 hours on the iPhone 4S. The iPhone 4S is also slightly heavier at 4.9 ounces than the iPhone 4 or iPhone 3GS, both of which weigh in at 4.8 ounces.
