Is it the right time already to sell an iPhone 4 and get an iPhone 4S upgrade?  Run through the changes in the new iPhone below and see if you are long overdue for a smartphone change.

The Retina Display

The iPhone 4S sports the famed Retina Display that can also be found in the iPhone 4. Though the Retina Display is good, there are now better screens that can be found on other smartphones like those from Samsung.  This doesn’t mean though, that I don’t like the Retina Display. 

The A5 Dual-Core Chipset

The iPhone 4S is now clocked at 800 MHz thanks to its dual-core A5 chipset. Apple designs their own hardware and software (and lets Samsung manufacture it, if we are to believe Apple) which is why they are the best in making excellent operating systems for smartphones.

The A5 chip is best used with gaming. It can enhance even the biggest data-eating app or program. This is why the iPhone 4S is really speedy and it can process up to two times faster than the iOS 4.

Experts say that when it comes to games and processing graphics, the iPhone 4S is capable of bringing seven times more fun than any other iOS made.

Battery Life

The iPhone 4S is a hundred times shorter on battery life than the iPhone 4 in standby. Even if this is a helpless scenario, the iPhone 4S still will not disappoint new owners as it can stay efficient for up to 10 hours of video playback and eight hours talk on 3G.

Camera

The iPhone 4S now rocks with an eight megapixel camera with advanced lens. It has new optics and a larger aperture for taking flawlessly stunning photos.

It now has the "five precision elements to shape incoming light, which makes the entire image sharper." For a phone, the camera of the iPhone 4S is just breathtaking.

Not only can it take good quality photos, it can also record in high definition at an astounding 1080p. A user can also edit the video directly using the iPhone without purchasing any software or downloading added apps.

Siri

A lot of tech pundits believe that Siri, the artificially intelligent voice assistant found in the iPhone 4S is the best new feature. However, Siri is still in its Beta testing.

Siri is a good assistant wherein the user can command the phone to accomplish some basic phone task, ask for directions and set reminders. The new voice of the iPhone 4S can do practically anything as it has the ability to understand a spoken order and translate it to text.

Overall, Is the 4S Worth It?

The iPhone 4S is a worthy upgrade from the iPhone 4. Even if both phones look identical, there are enormous changes when we talk about its internal composition. These internal changes have transformed the iPhone 4S to a worthy king for the throne of the mobile jungle.

If you are a person who’s still undecided on whether you should get the 4S or wait until the iPhone 5 comes out (maybe later this year?), now is the time to decide!
