Reviews summary

Based on 41 reviews

While the iPhone 4s does not look much different from the iPhone 4, it does boast both hardware and software related improvements. As you may know, the iPhone 4 had some problems with dropping calls due to the placement of its antennas. The iPhone 4s has been redesigned to eliminate this problem, and it is no longer necessary to worry about how to hold the phone to avoid dropping important calls.

The processor is also upgraded, with the A5 CPU being used. This is the same CPU that is used in the iPad 2, though runs at 800MHz compared to 1GHz in the iPad 2. Even with the slight speed decrease, the phone still is one of the best performers on the market. Up to 64GB of storage space is available as well, which is plenty even for the most demanding power users. The camera on the iPhone 4s is one of the best on any cell phone on the market. The photos it can create rival a dedicated point and shoot camera, with rich color and impressive low light performance, making it a significant step forward from the camera on any iPhone before it.

The iPhone 4s also introduces Siri, which is a computerized virtual assistant built into the iOS 5 software. Using this new voice technology, you talk to Siri naturally and she can help you do anything on the phone just by speaking to her, making it easier than ever to check the weather, send a text, or put an appointment on your calendar.

There are a couple weak points, but nothing that spoils the experience. The latest 4G capability is still not available so users who wish for the fastest data transfer speeds will want to look elsewhere. The back of the phone is still constructed of glass making it easier to crack (when dropped) than a phone with a plastic back.

Not quite the deal it hopes to be

With a premium build, good camera and free accessories in the box, Alcatel's Idol 4S is a solid midrange buy... Full review

Intuitive navigation and layout but still no 4G

from Good Housekeeping

As with all Apple upgrades, the iPhone 4S is better and faster than its predecessor — and was easily our top pick for a premium phone for AT&T customers. Enhancements include a more responsive dual core processor, an 8-megapixel camera with improved sensors, a sharper display, and slick call quality (the phone switches between two antennas: one for calling, one for receiving). Apple also added some nifty upgrades with iOS 5, harnessing cloud capabilities and giving users their own personal assistant with Siri. Consumer testers found this device extremely intuitive and easy to use.... Full review

Neat design, fantastic camera, premium build quality

from UnleashThePhones

The iPhone 4S is just as excellent a smartphone as it’s recent predecessors. It delivers a huge range of functionality along with an entire ecosystem that all together makes it one of the best phones in the market right now. Things like AirPlay, which I’m a huge fan of, are neat little features incorporated which Apple has done a good job of pushing. And accessory-wise you’re spoiled for choice with an iPhone.

Admittedly, noone is really a huge fan of iTunes as a software package, but there is a bit of convenience in having a backup of your entire device, along with one app to d... Full review

Lack of a new design, full HD video recording, enhanced optics

from Techsmart
Whilst Apple’s new iPhone 4S may look like the outgoing model, its faster CPU, enhanced antenna and new optics combine to make it one of our top 3 smartphones currently on the market. Regarding Siri - it sure is an interesting concept, but we soon lost interest as the novelty faded. The iPhone 4S comes with an RRP of R7699 for the 16 GB model, R8999 for the 32 GB model and R10299 for the 64 GB model... Full review

A significant upgrade over its predecessor

from What Digital Camera
Apple reckons the iPhone 4S has the best camera ever produced for a mobile phone, and we reckon they might be right. It redefines what photographers can reasonably expect to get from a camera phone. The speed of use and quality of the results exceeds not only any other phone we've tried but also many cameras too. Based upon this test, compact manufacturers should start panicking now...

The combination of outstanding hardware, an exceptional OS and impressive apps make this the best smartphone available

from Top Ten Reviews
The Apple iPhone 4S is the next step in the evolution of the iPhone. Apple had already set the smartphone bar very high, and this device gives it a substantial nudge higher. The vast selection of iPhone apps continues to grow rapidly, expanding the phone's capabilities almost daily. The iPhone's computing capability is made possible by its fast A5 processor. Its video and still-camera capabilities far exceed previous editions, and the introduction of Siri, even though it's still in Beta testing, position this device far ahead of its competitors...

Better battery life, best smartphone camera yet, high pixel density Retina displays

from Pocket PC Central

Is the iPhone 4S better than the iPhone 4? Unquestionably. But are the minor speed improvements, upgraded camera performance and Siri enough to justify the upgrade for most iPhone 4 users? I don’t think so.

By all accounts, the iPhone 5 will be a major update to the line, with a larger screen, even faster performance, a new OS, LTE and possibly even new technologies like NFC. If you don’t mind spending $500 or $600 next year to upgrade to a truly new-and-improved iPhone 5, upgrade away. If not, don’t jump ship just yet; your current iPhone 4 with iOS 5 will carry you for th... Full review

Intuitive interface with improvements like notifcations and iMessage on a responsive handset

from Digital Versus
The iPhone 4S is as easy to use as ever, and sees the arrival of several improvements. The most substantial of these include visibly better photos from the digital camera and the faster processor speeds. The new voice services from Siri are a clear part of Apple's strategy to add more and more services to the basic product—we're just looking forward to seeing it work with some more apps...

Sub-par battery life, entirely new antenna system, graphics performance is amazingly better

from Pocketables

There were some of you who asked me why I would upgrade from a 4 to a 4S. To be honest, I wanted Siri and a different color.

But as I started using it more, I realized why Apple would release just a simple internal upgrade. This move positions the company to bring a brand new design next year, along with a few better specs, at the same price point. If Apple had chosen to release a new design, it probably would've been stuck running an A4.

That being said, there's no reason you need to upgrade if you've already got an iPhone 4. There isn't enough of a performance boost yet; we'... Full review

Delivers a complete package that's hard to beat

from What Hi-Fi
It’s testament to the quality of the iPhone as a piece of design and a piece of hardware that it remains so competitive. For audio quality, ease of use and the entertainment on offer from apps and iTunes, it’s hard to beat.But the screen looks small and some of the shine has gone from the iPhone’s crown. With a new model due in the autumn, Apple will surely look to deliver something revolutionary rather than evolutionary... Full review
