iPhone 4s – Full Phone Information, Tech Specs

The iPhone 4s is the fifth generation of Apple’s smartphone. While no differences to the phone’s external characteristics were made, this version of the iPhone released a year later after its very successful predecessor introduced a few changes to the 4s version compared to the iPhone 4, including increased battery life, extended wireless connectivity and a more powerful dual­core processor. The 4S model hosted major internal upgrades, including an upgrade to the Apple A5 chipset, and an 8-megapixel camera with 1080p video recording.

  • There were no external differences between the iPhone 4 CDMA model and the iPhone 4S, with the exception of a SIM card slot on the iPhone 4S. In fact, all changes were internal. However slight external differences between the iPhone 4 GSM model and the iPhone 4S exist, as said differences existed between the CDMA and GSM models of the iPhone 4.

  • The fifth generation iPhone was originally named the iPhone 4S – with a capitalized “S” – but was later stylized with a lowercase “s” in September 2013. The “S” stood for Siri – the 4s introduced exclusive personal assistant which was later included in the iPhone’s successors.
  • The iPhone 4 and 4S were designed by Apple’s leading designer Jonathan Ive. The 4th generation of iPhones differ from earlier Apple designs, as the bulges of the back panel as well as the band between the front and back were now gone and have been replaced with flattened surfaces. The redesign reflects the utilitarianism and uniformity of existing Apple products, such as the iPad and the iMac. The overall dimensions of the iPhone 4S are lower than that of the 3GS.
  • At announcement of this model, Apple said that it had plans in place for its new iPhone 4S to support many languages. Different features have different language requirements, such as keyboards compared to the word predictor and spell-checker, which needs a large dictionary of words. Language support is related to the iOS 5 operating system that the device launched with, although not always. The Siri digital assistant supported French, English, and German at launch. Since it uses a software based keyboard supported by the multi-touch display, it can support many different keyboard layouts without having to change physically. The iPhone 4S can display different languages and scripts at the same time.
  • Apple held the Let’s Talk iPhone event on October 4, 2011, when Mike Capps demonstrated Epic Games’ Infinity Blade II, the sequel to Infinity Blade, on an iPhone 4S. Mike Capps boasted that the game used Epic Games’ Unreal Engine 3 and featured the same graphic techniques used in the Xbox 360 game Gears of War 3.
  • Reception to the iPhone 4S was generally favorable. Reviewers noted Siri, the new camera, and processing speeds as significant advantages over the prior model.
  • The iPhone 4s was succeeded by the iPhone 5 as Apple’s flagship phone on September 12, 2012, but the iPhone 4S remained in production, albeit being sold with reduced storage (from 16/32/64 GB down to 8 GB.)
  • Even though this model was discontinued officially on September 9, 2014, following the announcement of the iPhone 6, it later supported as of iOS 9.
  • During the course of its lifetime, the iPhone 4S is the best-selling iPhone ever produced and it is the first iPhone to support five major versions of iOS: 5, 6, 7, 8, and 9.
  • This version is also the last iPhone to have the original 30 pin connector (replaced by the Lightning Connector when the iPhone 5 was released).

  • Reading about the iphone 4s, a question came to my mind: Do you remember some of original iPhone slogans over the years?: The two main slogans for the original iPhone were “Apple reinvents the phone” and “This is only the beginning.”The next model, iPhone 3G was marketed as “The first phone to beat the iPhone” or “The iPhone you have been waiting for.” the iPhone 3GS was released as “The fastest, most powerful iPhone yet.” For the iPhone 4 it was: “This changes everything. Again.” The iPhone 4s was known as “The most amazing iPhone yet”, and the iPhone 5 as “The biggest thing to happen to iPhone since iPhone”, while for iPhone 5 Apple launched its slogan: “Forward thinking.”

    These are iPhone slogans throughout time.

  • if you mean a C-HUB as a multi – port adapter – as opposed to a USB-C cable – you probably need an adapter from for the 30 pin charger to fit into the newer generation of ports – based on minimal research there is a lot out there, as I am learning – quite unnecessarily, from my vantage point as a consumer – but I digress – As long as the c- hub device has a USB port – why not?, as your original 4S charger will have this as well. If you do not have space on your c-hub device to suit all of your needs, again, you may have to find a 30pin adaptor for connection to the newer generation of ports – Awareness of speed compatibility and all sorts of electrical gobbledygook that actually is important regarding your equipments requirements, magnetic fields and such matters to avoid short-circuiting your equipment or damaging batteries should be kept in mind to a point. Find yourself someone you can trust when buying your equipment to respect your needs and guide you well. Otherwise – research and take pictures of what you are looking for because – I am learning some of this the hard way and jargon is what it is. Hope this helps along your journey –

  • Need to purchase iphone 4s. Does it have a 4g network? Does the battery drains easily?

  • I was just rooting around in one of my catch everything drawers and came up with two of my long lost friends. My iPhone 4 dressed in undertaker black and my iPhone 4s in angle white.
    They are still as beautiful, tough and rock solid as they were when I got them. I’ve decided to get a BYOP SIM card for the 4s, it has a SIM slot, the 4 doesn’t so I guess the undertaker will make a great paperweight on my cluttered up desk.
