List of iOS devices

The reverse sides of an original iPhone, iPhone 3G, and iPhone 4. The iPhone 3GS (not shown) has an appearance very similar to its predecessor, the iPhone 3G.

A size comparison of the iPhone 3G and iPad.

This is a list and comparison of iOS devices designed and marketed by Apple Inc. The iPhone is a multimedia smartphone, while the iPod Touch has no cell phone hardware. The iPad is a multimedia tablet. All three devices function as digital audio and portable media players and Internet clients. The Apple TV is a set-top box for streaming media from local and Internet sources to be displayed on a connected television set and has no screen of its own. They all run iOS.
It is easy to upgrade the operating system, and is completed through iTunes. A new version tends to be released once a year, and is normally free, although iPod touch users were previously required to pay a fee. Apple upgrades its products' hardware periodically (approximately yearly), and each model is known as a "generation". There have been four generations of the iPhone, four for the iPod Touch, and one for the iPad. Older models of the iPod touch are available at retailers at a reduced priced but are no longer available on the Apple Store. The older models of iPhone is still available at a reduced price.

Comparison of models

 Battery life

Side view of the original iPhone (right), iPhone 3G/3GS (center), and iPhone 4 (left). The original is made of aluminum and plastic; the iPhone 3G/3GS is made completely from a hard plastic material;^[48] the iPhone 4 is made of stainless steel and hardened glass.

The reverse of the iPhone 3G (left) is almost identical to that of the 3GS, differentiated only by the latter's reflective text.

The fronts of the original iPhone (left) and the iPhone 3G are almost indistinguishable.

Apple runs tests on pre-production units to determine battery life. However, these are purported maximums ("up to"), and actual user experiences vary.^{[14][49][50][51][52]} All numbers are in hours unless specified.

 Display

The 3 ½-inch display introduced with the original iPhone has been used almost unchanged in all models before 2010. The iPad naturally has a much larger display and also uses a different aspect ratio and resolution. The iPhone 4 and iPod touch 4th Generation, on the other hand, keep the physical dimensions of former models, but doubles the resolution in both dimensions, thereby quadrupling the number of pixels.
Apple cites the smaller display as having a diagonal size of 3 ½ inches (supposedly exact), i.e. 88.9 millimetres, but the pixel density values they publish suggest that it is in fact 90 millimetres exactly, which would repeat the same unit confusion as seen with floppy disks.

Published versus calculated values for pixel density in pixels per inch ("ppi")
