This isn't the iPhone 5. It is the iPhone 4S, which ushers in the world of iOS 5 and is unchanged from the iPhone 4. That's fine with us, except that we'd like a larger 3.5-inch, 960 x 640 Retina display.

Basic features

The 4S inherits all the standard iPhone features from the preceding models, including the calendar, voice memos, weather and stock apps, the various clock features, Google Maps, the compass, text messaging and e-mail, and the Notes app. The iPod player is there as well; the 4S splits your music and video libraries into two separate icons. In another change, the 4S also offers an upgrade to Bluetooth 4.0. Though still a growing technology, Bluetooth 4.0 uses less power and will enable the iPhone to talk to small battery-operated devices like Nike+ sensors and fitness machines at the gym. For more on Bluetooth 4.0, check out this deeper dive from Nicole Lee.

Video&Audio formats:

1. H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
2. MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
3. Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

From above formats, you can play full HD 1080p movies on iPhone 4S.

Camera

The iPhone 4's 5-megapixel camera was already great--especially when you add a third party app--but the iPhone 4S' is significantly better. The 8-megapixel camera offers autofocus, flash, f/2.4 aperture lens, and a backside-illuminated CMOS sensor that allows 73 percent more light than the previous sensor and should deliver better low-light performance. A hybrid IR filter is also onboard for better color accuracy. Apple also claims the new camera performs 33 percent faster than the iPhone 4's camera, and the A5 processor has a built-in image processor that adds face detection and 26 percent better auto white balance.



iPhone 4S vs. iPhone 4: what's changed?



Update: We spent a few days shooting with the iPhone 4S's eight megapixel camera, and were quite pleased with the images it was able to capture. We were slightly less impressed with the smartphone's battery life, however -- after the same shooting period, the iPhone 4 had 52 percent remaining, while the iPhone 4S had just 30 percent left.

The good:

Apple's iPhone 4S has a faster processor and an upgraded camera, all the benefits of iOS 5, and a useful and immensely fun voice assistant. Call quality on the Sprint model is admirable, and the data speeds, while certainly not 4G, get the job done.

The bad:

It's about time we get a larger screen and also limited at MOV, M4V, MP4 video formats. You have to convert MKV/AVI/MTS/WMV/MPG movies to iPhone 4S for enjoying via a third Apple Device Video Converter software.

Summary: The iPhone 4S isn't the king of cell phones, but it's part of the royal family nonetheless. Even without 4G and a giant screen, this phone's smart(ass) voice assistant, Siri, the benefits of iOS 5, and its spectacular camera make it a top choice for anyone ready to upgrade. Hope you enjoy the Apple Device iPhone 4S reviews post!
