What is the iPhone 5S?

Apple’s iPhone is one of the most popular and highly anticipated smartphones in the world. Whether you love or hate Apple, the original iPhone revolutionised the way we view and use our phone and, at one time, was the only smartphone you would consider buying.

These days there are a whole host of manufacturers that create great smartphones, from Sony to LG and HTC to Nokia, while Samsung has sold hundreds of millions of its Galaxy series, led by the Samsung Galaxy S4.

Watch the iPhone 5S video review

Launched alongside the more price conscious iPhone 5C, the iPhone 5S is Apple’s latest attempt to reclaim its 'king of phones' crown. It’s more than twice as fast as its predecessor and comes with an improved camera and a brand new feature none of its competitors can match.

Whether you’re an Apple fan or an Android aficionado we go in-depth to reveal whether the iPhone 5S and the new iOS7 update is all it’s cracked up to be.

iPhone 5S - Design and Features

The iPhone 5, launched last year, arrived with a 4-inch screen and diamond cut aluminium body. As is Apple’s way with its S phones, the iPhone 5S shares the same design. At first glance it looks identical, but there are some small changes in the colour options, as Apple has added the much sought after gold option, while the 'black' is now a lighter 'space grey'. The silver and white one we have, however, is exactly the same.

It’s an angular, timeless design – elegant and slim. In hand the cut aluminium feels premium and solid, but the iPhone 5S is far lighter than most other phones. At just 112g it initially feels a little too light, especially if you’re used to the iPhone 4S's glass and metal body. However the build is excellent and the 5S certainly doesn't feel flimsy the way some lighter phones can.

The highly engineered body feels quality, but it isn't the most comfortable. The diamond cut edges are a little sharp, not sharp enough to cause any real discomfort but slightly more rounded edges would make it easier to hold for long periods of time.

However, iPhone 5S is thin and light enough to easily warrant a case, whether it’s the pricey £35 leather case Apple announced with it or a third-party one. Using the leather case significantly softens the phone and makes it much more pleasurable to hold.

A double LED flash is next to the camera while on the front the screen bezels are slim. The home button is detailed in a metal ring that provides a useful function, the Touch ID – more on that later.

All buttons are instantly accessible using one hand without having to ever juggle the phone. The one difference it has from most other phones is that the 3.5mm headphone jack is at the bottom. It’s a little odd at first, but actually makes sense when you consider that a phone goes top first into a pocket so you don’t have to flip it round when you take it out.

As a 4-inch phone the iPhone 5S is significantly smaller than all its direct Android and Windows 8 competitors. Deciding whether the smaller screen is a benefit or weakness will depend entirely on you and whether you value screen real-estate over ease of use.

Samsung has managed to keep the Galaxy S4 as tidy as possible, but its 5-inch screen means that it is more of a handful and it can be tricky to reach some areas of the screen when used one-handed. The 4.7-inch screen on the HTC One is slightly more manageable.

From left to right: the iPhone 5S, iPhone 5 and Samsung Galaxy S4

While the iPhone 5S trails behind this competition in terms of sheer size you might find it much more comfortable to use day-to-day if you have average sized hands. It also tends to fit in a pocket easier.

So the 5S looks likes its predecessor, but that's where the similarities end .

iPhone 5S – Touch ID

We've already mentioned that the iPhone 5S has an ace up its sleeve. It is a finger-print scanner called Touch ID, discreetly integrated into the metal ring around the iPhone 5S's menu button.

This could easily have been a gimmick, a feature that offers a lot of marketing potential with little functional use, like the back buttons on the LG G2.

Thankfully Apple has made no mistake with it, just the way Sony has managed to crack waterproofing a phone with the Xperia Z1.

Initially you need to set up your fingers or thumbs to be recognised. This takes around 30 seconds and involves tapping the button repeatedly while the complex contours of your fingerprints are mapped. You can add up to five fingers, whether they're all your own or someone you want to share access with.

The key thing Apple has managed to achieve with Touch ID is flawless execution. It's easy to forget that your phone is locked at all when a tap of the home button to wake the iPhone 5S also unlocks it.

If you never lock your phone then you'll have little use for Touch ID, other than to authorise app purchases. Even if you do lock your phone you might think tapping a four digit PIN or drawing a symbol is not too much of a barrier to access. However, once you experience the ease of Touch ID it's hard to not become a convert.

Aside from the fact it works so well (even when you turn the phone upside down the iPhone 5S unlocks without a hitch) it is far more secure than a four digit PIN or symbol. A fingerprint is yours and yours alone. While there is a way for the very determined to copy your fingerprints, it's highly unlikely to be worth the effort. You also can't forget your fingers!

Fingerprint scanning leads us to a source of quite appropriate concern. No-one wants Apple to have millions of fingerprints on a massive database somewhere, no matter how well protected. Regular news and rumours about how the NSA and other governmental organisations demand, and are given, user information from companies brings trickles of sweat to even the most innocent and blasé.

So how has Apple combated the concern of iPhone 5S fingerprint databases falling into the wrong hands? In quite a simple way, they don't keep any. Fingerprint scans are encrypted and stored locally only. In other words only on the iPhone 5S – in one secure section of the CPU, not in the user accessible memory.

If you're extremely security conscious or have highly sensitive data on your phone then fingerprint locking alone may not be enough. It's here that Apple could have upped the security ante by allowing the option of dual-factor authentication – supporting the option of finger-print unlocking with a PIN. We hope this will be an option in future iOS updates.

The bottom line is Touch ID is not an industrial grade security measure, but that's fine. It is more secure than a four digit PIN and means you don't have to constantly input your iTunes password to make purchase, two things that make it a more than worthwhile addition.

iPhone 5S - Screen

The iPhone 5S has kept faith with the highly responsive 16:9 Retina-display 4-inch screen of its predecessor. The display offers a resolution of 1,136 x 640 with 326ppi. On paper it falls behind the 400ppi 1080 Super AMOLED screen on the Samsung Galaxy S4 and even further behind the 468PPI on the HTC One. To the human eye, however, there's very little in it, and the iPhone 5S is pin sharp and text looks crisp at all levels of zoom.

Regardless of the lack of iterative display improvements the iPhone 5S has one of the best screens on the market. Set it to maximum levels and it is a lot brighter than the other two, as well as offering better colour accuracy and a less 'saturated' look than the Samsung Galaxy S4.

Apple has also managed to remove a layer during the screen production process. This means that the images are not recessed but in fact almost appear to float on the glass. The effect is even more striking when combined with the new iOS7 parallax wallpapers that shimmer under the icons as the 5S is moved.

Where the screen of the iPhone 5S falters a little is with low-light video and images. Shady scenes are not quite as dark as they could be and blacks not as deep.

However, if there was one thing Apple could afford to retain from the iPhone 5 it was the screen. Considerations on whether it is right for you should centre around its size rather than quality. Is 4-inches big enough and do you intend to multi-task on a phone?

There have been some iOS 7 improvements to help with multitasking but you still won't be able to have two apps open on-screen at the same time. What you can do is double press the home button. This offers up a preview list of open apps, lets you dismiss them by flicking up, scroll through multiple pages if it's a browser or just easily flip from one app to another.

This is just one of the new features on the iPhone 5S, but there's a lot more to iOS 7.

"Will going from 32 to 64-bit benefit users? Well 64-bit will help the 3D graphical capabilities of the iPhone 5S. It’s also required for high security apps. And Apple will need that for a unique new feature on the iPhone 5S, the fingerprint scanner."

Errr... that is simply not true. The move to 64 bit does not affect the 3D rendering pipeline in any meaningful way, and it certainly doesn't magically provide anything for high security apps.


September 11, 2013, 12:51 pm

64 bit is great for the desktop for memory and cpu intensive activities such as rendering and editing video. The fraction of a second better performance on usual phone applications is meaningless for iPhone 5s. The fingerprint scanner is just a distraction for being the same phone as last year. There is no innovation, no bigger screen, no additional button for quick instant camera function, list could go but Apple have lost new ideas.


September 12, 2013, 8:06 am

I wonder how many people are like me and don't even bother with a lock screen at all, making the fingerprint sensor worthless. The screen is still dinky by today's standards which probably will cause people to jump to the Android wagon.

Hi! :)

September 14, 2013, 7:49 pm

Who gives a damn about how big the screen is?! I can't believe big screens are still a thing! IT'S A PHONE NOT A TABLET! Call me old-fashioned, but I'm one of those people that actually wants my phone to fit in my pocket... much less, my hand! I mean what do you people do on your phones?! Watch a movie?! Um... hello! It's called A TV! Yeah we still have those! If you want a bigger screen get a tablet! The iPhone was built to be extremely efficient while also being EASY TO USE! That includes portability- fitting it into your pocket- and manageability- fitting it into your hand! I'm sorry, but when I have to call someone, I don't want to have to hold a tablet up to my face, so to speak. I mean what's next people?! The brick?!


September 14, 2013, 10:11 pm

What innovation does any other phone or Company do? All Samsung does is create really big screens. If Apple every fell to the same level as other Companies and created a 7" phone screens then everyone would love them. Don't bad mouth a company,because they feel differently on whats a good screen size.

LOL, so you call the following ideas "new" innovation?
Bigger screen
Extra button, for quick camera use.

What a joke.

Do you not understand how Apple produces phones? Every 2 years they give us a new design or model, however every opposite year they just update the current model. Quit bitching, because you didn't get what you want even though everyone knew the (s) phones don't change design, just internal mostly.

If Apple gave new design every year they would of been out of the phone business 2 years ago. The way they operate is how they have to operate, when they don;t produce 50 different models of phones like Andriod.

With all this discussion on wether or not Apple is done innovating, here is my take. I think the race between Apple and its competitors is a classic example of the Tortoise and the Hare (Apple being the Tortoise). I think that Apple knows that it is impossible to create astoundingly new and innovative products each year. So instead of throwing everything that it has into every new product, Apple is playing it safe, while it is actually innovating behind the scenes. Meanwhile, the Hare (Samsung, mainly), is running the race as fast as possible, delivering every new technology it creates, wether it is ready or not. Eventually, this will come to an end. In terms of the update from the S3 to the S4, this was view as a largely incremental update to the flagship Galaxy line. I believe that the smartphone market has grown and innovated so rapidly, that it would be in both company's interests to stop trying to one-up the competition, but instead focus on how they will be able to innovate for years to come. This is something I believe Apple figured out a couple years ago, and something Samsung is figuring out now. It will be interesting to see the smartphone market two or three years from now.

Those who do not lock their phone are high stake gamblers! Given the amount of personal data that is stored on a typical smartphone and the increasing threat from identity fraud, not taking security seriously is simply insane.

The addition of an effective finger print scanner in the new iPhone is a welcome addition, especially for those who hate lock screen PINs, and will hopefully encourage those who currently fail to secure their device to do so.
The screen size may still be small by comparison to some other devices but will equally serve many, who prefer a more manageable size phone, very well. I have GN2 and although it is sometimes nice to have the big screen I often wish I had a smaller lump to carry around!

Many Android users in fact pick up the smaller versions of the their large screen counterparts, thus the Samsung mini range. So I doubt this will cause an increase flocking to Android.


September 15, 2013, 5:18 pm

Hmm, A no-longer-acceptable paltry 4 in. 326 ppi screen is left in the competitions' pixel dust.. I phone s boasting the same screen as their now cheaper variant 5C? Non accessible battery and with nearly the same still poor talk time? (Don't throw those pocketed chargers away ifans!) Still inaccessible batteries and non-expandable memories i.e, no SIM or micro SD card slot? A now paltry 8 megapixel camera and a still primitive IOS 7 widget architecture?! Cmon iphone, if this is your best response to 5 to 6 inch HD front and rear displays and against stratospheric S Pens etc.Android products, then Steve Jobs is spinning a hole through his casket this week. Sorry Steve, (Jeff),seems I too will have to go get me a new Note 3 for the next couple of years.. maybe you'll have caught up by then.

I recently jumped to a Google Edition S4. Everyone seems to thing this is a great phone, but in my experience not so much. I get terrible battery life. This must be something I'm doing wrong since it's really bad, much shorter than my old 4s running the same stuff. In general Android is great, but so is iOs, and the Apple software is more polished and simply quicker, or more responsive, without lags. Another shocker for me is the difficulty of controlling the phone through the headset. I'm sure there is some work around to get the iphone functionality (controlling music, answering the phone, etc.) but it's not smooth and simple out of the box. Finally there is the Samsung screen, which to my mind has terrible color balance. Lots of great things about the Samsung, but also some ragged edges.

Nick Schmidt

September 16, 2013, 3:39 am

So my question is; since you don't like the battery life, you don't like the lag, you don't particularly like the screen, and you say that iOS is equally as good of an OS, what do you like more about your S4 than your 4S? (By the way I just now noticed the similarity in phone names...) I'm not saying that you shouldn't like android, I just don't see why you made the switch.


September 16, 2013, 9:24 am

Bitching is a user prerogative. A bigger screen? how do you differentiate what screen size makes a phone not a phone? The iPhone 5s has the same screen as last years model, it's a good size but adding another 0.5 inch would have made the 5s closer to its competition. I have a samsung S4 and and an iPhone and I find myself using the S4 when browsing or using apps for photos or video because it has a bigger screen. Any screen bigger than the S4 is too difficult to carry and in my opinion hence not a phone.


September 16, 2013, 6:26 pm

Not everyone likes the gigantic screens on android phones, personally I strongly dislike those large phones, I am sure that I am not alone. There are phones and tablets. Those 5 inch phones are far too big for a phone, and too small to be proper tablets. Also, why do one need those 1080p screens on phones. I have never looked at my 55inch samsung series 9 tv and went I need more pixels! All a 1080p screen would do would be draining battery life quicker. Personally, I would have like apple to put a 720p screen on the iphone just so that it would be a standard resolution rather than the weird one they have now.

Also the build quality of those android phones are just so poor, they just feel so plasticy and cheap, it certainly does not match its price tag (exceptions to the asus padfone infinity and the HTC one). I try to jumped to the android by buying a galaxy s3 to replace my iPhone 4. I expected the samsung to be lightening fast with its quad core processor, but it simply does't feel that. Battery does not match at all with the ads, I still need to charge it everyday after heavy use just like my old iphone.

I am happy with how the iPhone is progressing. Not sure why people has so much expectation with apple, they are being deigned by human beings, not miracle maker. Same goes with samsung. The eye control with their phones are fantastic applications of the technology, but it is not new technology. My 20+ year old canon eos 5 uses a cam to track my eye so that the camera would focus on the subject I looked at. That was back in 1992!

I do like the iphone5 and there is a good chance that it would be getting one, it would replace my iphone 4 which I still use today. In the end, if you feel that apple hasn't done enough, just wait a year and something new would come out!


September 17, 2013, 5:23 am

Bigger is not always better while the s4's screen isn't too big yet it is getting there and I prefer the smaller 5s screen and really I don't notice much if any difference in screen quality between the two in real life and with the processor I don't care how many cores or ram space there is ios has always been snappier and smoother than android on any device I've tried.

i have large fingers and i have survived previously without large screens. i think apple keyboard is better than the rest but with apps like swiftkey which improves the typing experience on my s3 helps. I find it hard to read and type on browsers often because half the keyboard steals half the screen. If a girl mate with small hands and is tech stupid i would say go for the iphone but otherwise i think its stupid to spend so much when htc has caught up on build quality.


September 17, 2013, 12:39 pm

Boring old Apple . I use to love the apple phones but I opened my eyes and brought a.Note 2 and 12 months on Its been a true friend . I love the big screen expandable memory the long battery life have bought 2 more batteries and so cheap, plus not being tired to Apple itunes and so much more. Going to upgrade to the Note 3.
Apple shows little innovation considering the money they make . Open your eyes silly fan boys.


September 17, 2013, 4:10 pm

As a developer, I'm excited about the upgraded processor. This progress in combination with improved JavaScript rendering and better mobile web frameworks will eventually lead to the downfall of native apps so we can finally build and maintain one responsive mobile web app instead of 3 to 5 native apps. Another couple years of these improvements and we're there. And when that day comes, apps will be released at an astounding pace.

The problem for me, Barry, is that I'm so used to the way Apple's software works that while I changed over to Samsung Gallery S4 four months ago, I'm still not used to it. The extra software tricks were fun but I don't use them on a daily basis. If I ever change back, what I would miss is the amazing, huge, beautiful screen! I read all my kindle books on the S4 and almost never on the iPad. Samsung is a great company, especially for televisions.


September 17, 2013, 9:28 pm

For once a Comment thread that actually has some balanced and decent views from Apple and Android Fans. Refreshing to see this and not just a massive slagging match. Personally I'm an Apple fan but have had an Android phone and loved it. For me there is something special about using an Apple product. My wife on the other hand loves her Samsung GS3 and doesn't want an Apple phone. Isn't it nice to just have a choice?


September 17, 2013, 9:57 pm

I'm planning on getting the 5s because I've had my 4s for 2 years now. I'll admit I'm not terrible excited about the 5s. If they let me have the same hardware and software in the 4s size I would be thrilled. I'm not updating my ipad 4 to IOS7 either. I hate and despise the look. If I have a change of heart with the 5s maybe I will, but now the design looks like cheap Android and Microsoft - - a fisher price design. Jony Ive is an idiot.

I've moved to a Lumia 920 and the difference form the iphone to the Lumia is amazing. My old iphone 4 was incredible better. It simply worked,. The Lumia I can't even hold it...it has buttons everywhere and I'm always pressing one of the without wanting. It drives me completely crazy. After two months of use I really regret having spent money on ii. My old iphone 4 was miles away! Iphone is a phone!


September 21, 2013, 2:45 am

I disagree. Screen size makes a difference in what you can see, both in true resolution and inclusiveness. A larger screen wins hands down. Big screens is NOT what Samsung specializes in, they also provide excellent and 'true' connectivity...ie true USB without the proprietary bs that Apple insists upon. You can connect whatever you like to a Samsung - try that with Apple (especially as they say "No" you cannot).

Obsolescence is a true issue with Apple. Without the 'innovation' others are claiming for them, obsolescence is a real problem. Devices should last years, not discarded after such a short cycle with a stagnant OS design.

And the absurd fanboy drivel about 'plastic' being 'cheap' and inferior is so typical of creating arguments out of nothing. The iPhone 5C is plastic (call it polycarbonate or whatever you like) but the argument that Apple makes for it APPLIES to their competitors' products - always have. Double standards and emotional bias typically rule the commentaries, not objective observation.

I've used iOS devices and currently use the Note 2. I use it for the 'features' it offers - rarely as a 'phone.' Seriously, stop comparing it to a phone and arguing it's 'too big.' Like the Dell Streak 7 this 'Phablet' (whatever) HAS a phone feature - but the real purpose of this device is its multitasking ability and horsepower. Connect the Note 2 (now 3) to an HD monitor, (Apple) bluetooth mouse and keyboard (lol) and run it like a PC. You can! You can even run multiple videos, email, SMS, Skype, and background music ALL AT THE SAME TIME. That is horsepower.

The iPhone 5s boasts an A7 64-bit processor and claims it is twice as fast and allows security and video enhancement. SMH. Because of Apple's locked environment and inaccessible API's you don't see the 'lack of horsepower' under it's shell, despite newer processors. You'll never get an iPhone to run like a computer until Apple gets off it's high horse and considers real innovation and user-freedoms as paramount to designing feature rich and powerful devices worthy of business environments (now somewhat limited)

Clicking photos, playing music, navigating maps and uploading personal data is a typical 'smartphone'. Being able to run multiple applications with freedom to connect to whatever you like AND see it in a respectable window frame (to name a few) is user empowerment - a true 'smart' device.


September 21, 2013, 12:42 pm

I don't disagree with a lot of this, but you can't seriously say any other phone company is more innovated then Apple. A bigger screen is not innovated any in shape or form. A camera with more mp is not innovation now days, maybe 10 years ago.

So many ppl expect the world out of every iphone, but they can't do everything at once, or what are they gonna do next year?

I think the iphone 5c is crap and would never buy it. And Apple is very strick when it comes to what they allow you to do. How ever I jail break as soon as possible, so that doesn't affect me very much.

True Apple fans understand how Apple works and deals with it because of the quality of phones they put out. Apple has done the same phones practice for 5 years, not sure why ppl are still expecting different. I promise a bigger screen will come next year, I think it will be 4.7 at the biggest, I couldn't imagine anything bigger:

I initially thought that about IOS7,I thought im not updating my ipad no way! but i had a go with my iphone 4s-Three days later ive now updated my ipad! Its actually brilliant with so many new features! Actually feels like ive got a new phone.

September 25, 2013, 12:01 pm

Not turning my head in any way. It's just another under-delivering Apple product with just enough features missing so when they make the iPhone 6 they can sell you some more stuff than android and samsung already have...


September 25, 2013, 2:15 pm

I don't want big screens on a mobile. 4 inches is plenty big enough. if I want to watch a film on a trainn than every phone will be a compromise anyway, so don't see why you would want to sacrifice portability for trying to get a phone to deliver a cinema experience for something for which it is not inherently designed, when a tablet will be do the job better and doesn't require always being instantly accessible like a phone.
