iPhone 4 Review

March 13, 2012

Currently I use an iPhone 3GS on pay as you go, which I am happy with. I often wondered if it was worth upgrading to the iPhone 4 or 4S and was really pleased to be sent an iPhone 4 to review. This gave me the chance to experience what it was like and to decide if it was worth moving to this phone in the future or one of the other alternatives that are currently available on the market.


The first thing that struck me about the phone was its look. The iPhone has changed shape since the 3G variety.

iPhone 4G

You can’t really tell when you look at it head on, but when you hold it in your hand you can definitely feel the difference.  It has exactly the same weight at 137g but the dimensions are 115.2mm x58.6 mm x 9.3mm which is quite a bit smaller and slimmer. The design is also different as well, it is no longer curved with a plastic back but is much squarer in shape. The front and back are made of glass, reinforced glass fortunately and the side is rimmed with steel which is ten time stronger than normal steel.  It makes the handset a lot stronger than the old version, I found the plastic tended to crack.

The volume buttons have changed shape to become round buttons with + and – marked on them and the volume on off switch remains the same but all the buttons have a new metallic look.

The on off button is still on the top of the phone and the headphone jack. The headphone jack feels more flush with the top of the phone than the previous model. The little tiny hole next to it is a microphone which is for noise cancelling.

The bottom of the phone has the usual space for the charger or docking and on either side we have the speakers. The right hand side of the phone appears blank but the sim card is actually inserted here. The iPhone 4 actually uses a micro sim card rather than the normal sized sim card so you will need to change your sim card.

If you look at the front it all looks very similar to the iPhone we are used to seeing. The screen is the same and there is that one big button on the front that is used to move between applications.

Once I got used to the change in size it felt nice to hold and having a slightly slimmer phone was definitely better. In the box you get the usual charger, USB cable , headphones and metal tool for opening the sim card slot.

User Experience


The Apple iPhone 4 has a new high resolution display called the Retina Display. The display is really crisp and clear, and it should be as it has 326 pixels per inch all packed into the 3.5 inch screen.  In normal use you do not really notice the difference but when you are zooming in on a page you do notice how much clearer and crisper the lines are.


The user interface is really intuitive and easy to use. If you want to use an application tap on the icon on the screen.  If you want to leave the application hit the big round button at the bottom. If you want to move the icons about the screen press on one and hold it and the icons all start wobbling about.

iPhone screenJust press on one to move it around the screen. If you want to delete it altogether then press on the x at the top of the icon and it will remove it from the phone. You are not able to delete the pre-loaded applications however which is probably a good thing.  It is all really simple and easy but also looks good while it does it.

iphone ScreenIt also handles multitasking. If you hit the home button twice you  get a little row of the most recently used applications on the screen, the most recently used one is on the left.  You can scroll along to the right to choose one and it goes back to where you were in the application before you left it.  If you scroll left along the icon list  you find useful music control buttons and a button to lock the screen orientation.

The screen will rotate as you rotate the phone and this button will stop this from happening.

Making Phone Calls

The iPhone 4 makes it easy to make phone calls and the sound quality was clear and crisp. I was aware of problems reported about loss of signal when using this model but I did not experience this. On the iPhone 4 you can also make video phone calls using Face Time but I honestly never saw the point of doing this so did not try.

Messaging and emails

It is really easy to set up numerous email accounts using the iPhone 4 and it is easy to move them between accounts, folders and delete them as required. Messaging is similarly easy to use and I like the way that messages are threaded so you can read back on all your exchanges with a particular person. It is also really easy to use MMS, if you want to add a picture to a message just click on the camera icon, browse the pictures and tap to add.


The internet has always been really easy to use on the iPhone and the same is true on the iPhone 4G.  You can zoom in and out by pinching the screen. Bookmarks are easy to add as well. My main issue with the iPhone is that it does not have Flash support which is annoying when you hit a Flash based website.  If you want to copy and paste text it is easy to do this by tapping the screen, selecting the text and then choosing copy.


The camera is a vast improvement on the iPhone 3GS. It is a 5 MP camera with LED Flash and the sensors have also been improved to improve the sensitivity. Tapping the screen will focus the picture. The camera is easy to use and the picture quality is a lot better.  Video is in HD and can be recorded and edited from the handset which is great.


Applications and music for the iPhone are available from iTunes and the iTunes store.  The App store has an incredible range of applications, varying in price from free to over £50. The good thing is that whatever you are looking for you will definitely find it and you will never be short of a game to play on your phone.

Battery Life

The battery life will depend on what you do with the phone. If you sit browsing the internet, reading books, playing games then your battery will obviously be used faster than if you just have the phone in your pocket.  I found that the battery lasted much longer than on my iPhone 3GS in normal use.


I liked the iPhone 4, it was sleek and easy to use. I was very impressed with the improvements to the camera, the display is crisp and clear and the battery life is much improved. I would love to see how much the iPhone 4S has improved in comparison. My main dislike is the like of Flash support,which is annoying in a phone like this. I think if I was looking at upgrading I would definitely have a look at the other phones on the market now and compare them before I bought. There is  more competition out there now for the iPhone and a lot of very sleek phones with a smaller price tag.
