iPhone 4S enhancements
- Antenna Improvements
- Many critics lambasted the iPhone 4's antenna design in the wake of "Antennagate," but the iterative update of the iPhone 4S antenna shows that Apple has shaken out any deficiencies in the design.
- Quieter Vibration Motor
- The quieter motor in the iPhone 4S doesn't mean the phone's vibrations are weaker than those of the iPhone 4. I held the 4S in one hand and the 4 in my other; the strength of vibrations felt essentially the same, with the only difference being a distinctively loud BZZZZT coming from the iPhone 4.
- Audio Improvements
- The speaker on the iPhone 4S is NOTICEABLY LOUDER compared to the one in the iPhone 4. In some cases it's almost too loud...
- Bluetooth 4.0
- The iPhone 4S is the first iPhone to support Bluetooth 4.0, a low-energy Bluetooth spec that allows devices to sync via Bluetooth while consuming far less power than traditional Bluetooth devices.
- Video Mirroring
- The iPhone 4S is the first iPhone to support mirroring to an Apple TV via AirPlay, at 720p resolution.
- And, of course, Siri.
- You need this phone. You don't need to pay for it. Click "how does it work".
