What is the difference between iPhone 4 and 4s?

Our site continues to talk about the differences between smartphones from Apple. Before, we already managed to tell how the iPhone 6 and 6s, 5 and 5s differ, and today we’ll talk about the differences between the 4 and 4s models.

Recall that the iPhone 4 replaced the 3gs model in 2010, and the 4s version was released in 2011.


This is for the models of the last two generations, Apple decided to offer new colors, but the iPhone 4 and 4s have exactly the same colors – white and black, and the white version for model 4 became available much after the start of sales of the black version. Thus, by eye, it’s difficult to determine what exactly 4s is in front of you. However, there are still differences.

The first difference is quite insignificant – 4s weighs 3 grams more than its predecessor, which, however, is difficult to understand, even if you take the devices in turn in your hands. The second difference is much more important – in 4s another antenna is used in the form of a strip, which can be seen above the sound adjustment keys. This is the most significant difference in versions when it comes to appearance.


Siri existed as a standalone application, until the company that invented it was bought by Apple. For the first time in the form of software, Siri was included specifically in the iPhone 4s. Recall that Siri is a personal assistant and a question and answer system from Apple. Provides answers to questions and recommendations..

iOS 5

iOS 5, in turn, was presented along with the iPhone 4s. Of course, hardly anyone uses such an outdated firmware today, but if you are holding such an iPhone and iOS 4 is installed on it, then you have model 4, not 4S.


as for iron, there were not so many changes. For example, the processor has now become dual-core, and the amount of internal memory has changed: if previously you could choose 8, 16 and 32 GB of memory, then in 4s – 8, 16, 32 and 64 GB. GPU has become much more powerful.

The amount of RAM has not changed.


The main camera has changed. Now its resolution was 8 MP against the previous 5 MP. Images became clearer, color rendering improved, optical stabilization appeared.

The front camera has not changed (0.3 MP), but the main camera has the ability to record video in Full HD resolution.

As you can see, the changes are not so significant.
