iPhone 4S vs. iPhone 4

In the past few months, rumors about the coming iPhone 5 or iPhone 4S were in flood. Now finally Tim Cook brought the new iPhone 4S. And it will come into the market on October 14th, 2011. To upgrade or not to upgrade? That is the question.

We’ve taken an in-depth look at the key specs and seen how it compares to its year-older sibling – the iPhone 4.

Processor and memory

The iPhone 4S boasts the Apple A5, which is the same dual-core processor as the iPad 2. Apple A5, based on the ARM Cortex-A9 microarchitecture, is said to have twice the speed of the Apple A4 chip in the iPhone 4.

Siri

Siri is one of the lightspots of iPhone 4S. It is a voice-controlled personal organizer of a sort which will translate your more human, sentence-based commands into actions. So, for example, it can set alarms, read and reply to your messages, find restaurants and the like. The point is that it only comes with the iPhone 4S and not the iPhone 4 or below.

Video

One of the many features announced on the iPhone 4S is 1080p HD video recording. This is a nice improvement over the iPhone 4′s 720p HD video recording. The goodness does not stop there, however. In addition to 1080p, the iPhone 4S is equipped with video stabilization to help steady those non-professional, bouncy video recording skills. iPhone 4S video Converter | Total Video Converter

Camera

There’s a five element lens in the iPhone 4S instead of the four element in the iPhone 4, face detection and an 8-megapixel sensor. There’s 60 per cent more pixels, a larger f/2.4 aperture and an advanced hybrid IR filter that produces sharper and brighter images. The Camera app has also been improved and the shot to shot capability is twice as fast according to Apple. iPhone transfer | iPhone to Computer Transfer

Power and battery

The iPhone 4S has a slightly better battery life than the iPhone 4: up from 7 hours talk time on 3G to 8 hours. However, standby time is a cited 300 hours for the iPhone 4 but strangely this is 100 hours more than the iPhone 4S.

Storage

The iPhone 4S is still available at capacities of 16, 32, and 64GB. And the 16GB and 32GB version of the iPhone 4 line have been axed from this moment on, meaning that anyone who opts for the older model from new is limited to a rather small 8GB storage space only.

Wireless and data

The iPhone 4S boasts both GSM and CDMA capability, meaning it can be used on virtually any network across the globe. And iPhone 4 is separated into GSM version and CDMA version.

Deep Analysis of Three Major Upgrades on iPhone 4S's Camera

It is a truth that iPhone 4S reveives most attention among this years' devices. Although, many upgrades on hardware are not satisfied by most of the Apple Fans, iPhone 4S's camera is really satisfied me. On one hand, the brand new 800 million pixels back-illuminated CMOS camear is 60% higher than the previous iPhone 4, on the other hand, it is worth to talk about the series attempts of iPhone 4S on taking photogragh. Today, I will talk about the Three major upgrades of iPhone 4S's camera.

How is the photo effect of iPhone 4S?

In 2011, 800 million pixels is not at the leading position. Apple upgrades iPhone 4S's camera to 800 million pixels just as its always negligence to camera. Tough the hardware is not that outstanding, we can see that the previous iPhone 4's photo effect is superior to other mobile phones. So I am really excitting to see the iPhone 4S's camera.

This time Apple gives iPhone 4S's camera three major upgrades: 800 million pixels, 1080p full HD video and faster response speed.

Nowadays, people is more and more reasonable on camera's pixels. People no longer think that the higher the pixel is, the better the camera is. That's right. Under the same sensor technology, the high pixel sometimes brings users more noise and longer save time. At the same time, people now are using twitter and mobile phone's screen is now 1280 * 720 most, too many pixel can not be seen on the screen.

From my pion of view, I think the 800 million pixel does mean something for iPhone 4S. Why? Because iOS is a kind of operating system that "depending on app". On the publish conference, Tim Coke, the CEO of Apple, talks about iCould more than once which connecting iOS and Mac OS closely. On the big screen of iMac 27, people can enjoy every corner of the photo from iPhone 4S's 800 million pixels camera. That is to say that app makes iPhone 4S having such high pixels.

Altough cellphone video share tech is not that common for people as cell phone's photo share today, with the development of 3G and 4G, it will be a common thing for users to share videos from their mobile phones. From iPhone 4, iphone family support taking HD video (not the highest one), but its effect is acceptable, even better than some kind of DC.

Iphone 4S supports full HD video taking as the prediction of media and analysis. We can not say anyting about it before we see the official sample of its full HD video from iPhone 4S. But one thing is definiately true that 1920*1080 HD video will be used more and more widely with the development of monitor and mobile device's support to full HD video.

Some fans may notice that iPhone 4S supports electronic image stabilization, which is underestimate by people for its lowing the video quality. But if you use it in the right way, it is a great tech of course, especially when you are taking video. Under the support of right algorithm, its effect is perfect, even better than the first generation of optical image stabilization.

Image sensor, lens and image processor are the three major technology of a camera. Lens is the same, image sensor got major upgrade, now let us talk about iPhone 4S's upgrade on processor. Compare with BIGIC and Bionz's single processor, iPhone 4S's brain A5 is dual-core and responssible for processing all the info of iPhone 4S, including photo and video. The official saying of Apple is A5 is 7x faster than A4. From the two generation of iPad, we know that A5 is much powerful than A4. That is a good thing for removing the noise on the photo of iPhone 4S. Also iPhone 4S is 33% faster than iPhone 4 on system response speed. This allows users to take pictures on fast moving things and reduce the interval time of two photos. Apple said that on focus speed, white balance and metering accuracy, iPhone 4S is much better than its previous.

Let us come to the conclusion, altough iPhone 4S's upgrade is not that impressive than the iPad 2's, you can see how much Apple care from the iPhone 4S's camera. Enjoy your iPhone famaily with DVD Converter, iPhone SMS Transfer and Total Video Converter
