Apple iPhone 4S Comes with Key Design and Component Changes

October 17, 2011, By Leo Xavier

Many Apple fans were not at all impressed with the newly unveiled iPhone 4S. Although the device does come with good hardware upgrades and new features, those who were waiting eagerly for an awesome iPhone 5 were disappointed.

Some are saying that it will be hard for Apple to stay at the topmost position on the market this time around. But it’s too soon to say that and everyone should realize that the new device does have what it takes to rule the market again.

According to an analyst at IHS, the device is showing key changes in its feature set and component selection. These new additions might be more than enough to keep it in the first spot.


The device comes with a major upgrade to the apps processor, and it uses a higher-resolution and more advanced camera module, and a new cellular radio that makes it a true world phone.

As you might already know, the iPhone 4S comes equipped with the same dual-core A5 apps processor used in the iPad 2, most probably along with the same SDRAM memory at 4GB. This low density of memory shows how efficient the iOS operating system is, since many of the rivaling smartphones come with twice as much SDRAM.

The iPhone 4 models come with a 5MP camera. The iPhone 4S features an 8MP auto-focus camera and employs backside illumination tech, and the device uses a five-lens camera module. Earlier, a four-lens approach has been considered state-of-art.

Being a true world phone is yet another impressive feature. The new device comes with HSPA and CDMA radio capabilities, previously found separately in two iPhone 4 models.

The device appears to be perfect for multiple operators and multiple geographies. Thanks to this, the device will work on AT&T, Verizon and Sprint wireless networks, the top three networks in the US.

The device features an updated Qualcomm baseband processor, the MDM6610, which is discrete and is no longer integrated with the RF transceiver (dual-mode Qualcomm RTR8605). The device also likely uses three different power amplifier module suppliers: Avago, Skyworks and TriQuint.

Just in case you didn’t know, Skyworks and TriQuint were found in the HSPA/GSM version of the iPhone 4, while the CDMA version of the device makes use of Avago only.
