There is plenty of choice when it comes to smartphones, almost too much in fact. Chances are if you are reading this feature however, you have at least narrowed your options down to the iPhone.

So as you have discarded Android, Windows Phone and BlackBerry, as well as the other lesser-known options in favour of Apple, we are here to help you decide which iPhone is best for you.

Apple offers the iPhone SE, the iPhone 6, the iPhone 6S, the iPhone 6 Plus and the iPhone 6S Plus, so which one is the one for you? Let us explain the differences to help you figure out which you should spend your cash on.

AppleiPhoneSE-4ColorFan-PR_US-EN-PRINT

The Apple iPhone SE is the cheapest way to get your hands on an iPhone, despite being the newest in the line-up. It succeeds the iPhone 5S and like its predecessor, it will be the perfect device for some because its smaller size has the potential to make it a more practical option.

The iPhone SE has a 4-inch Retina display with a 1136 x 640 pixel resolution making it quite a bit smaller than its siblings. It measures 123.8 x 58.6 x 7.6mm and it weighs just 113g so it's the smallest and lightest iPhone available.

Storage wise, you get the same as the iPhone 6 and 6 Plus with the SE available in 16GB and 64GB models. This is something to consider if you take a lot of snaps or download a lot of apps. Colour options are silver, space grey, gold and rose gold, while the battery life is claimed to offer up to 14 hours talk time.

You'll find an 12-megapixel rear camera with all same features as the flagship iPhone 6S including 4K video recording, a True Tone flash and Live Photos. The front-facing camera has a lower resolution than the flagship at 1.2-megapixels but it does offer the Retina flash like the iPhone 6S. Touch ID and NFC are also both on board the iPhone SE meaning Apple Pay support, something which the replaced iPhone 5S didn't offer.

The iPhone SE might be small but it is powerful with the A9 chip under the hood along with the M9 co-processor which is the element that allows your phone to act as a step tracker, among other things. In a nutshell, the iPhone SE is a smaller and more compact version of the iPhone 6S with a slightly different design and a few missing features.

WHY BUY?

The iPhone SE is the perfect iPhone for those that want a smaller, cheaper iPhone and for those that aren't interested in the larger models.

You get many of latest features and some powerful specs, but in a smaller and more compact format. It's the iPhone to buy if you want to stay small but still want a great camera and good hardware.

PRICE: From £359

AmazoniPhone 6

The Apple iPhone 6 makes a jump in display size to 4.7 inches and offers a slight bump in resolution to 1334 x 750 pixels, meaning the same pixel density as the iPhone SE. Apple offers a couple of other features in this area too though, like display zoom, which isn't available on the new iPhone SE.

Under the hood is the A8 processor, supported by the M8 co-processor and although the iPhone 6 introduced a new and improved camera over the iPhone 5S, it is just 8-megapixels compared to the smaller iPhone SE. In terms of physical size and weight, you're looking at 138.1 x 67 x 6.9mm and 129g so it's lovely and slim, as well as light, despite its larger footprint.

The storage capacities for the iPhone 6 comprise 16GB and 64GB, meaning the same as the iPhone SE and the iPhone 6 is the device Apple first introduced NFC functionality to, meaning like its siblings, it can be used to pay for items under £20 in a number of retail stores using Apple Pay.

Battery life took a leap from the iPhone 5S's 10 hours to up to 14 hours talk time on the iPhone 6, but as the iPhone 6 is now the oldest iPhone offered through Apple, it only comes in silver and space grey colour options.

The design of the iPhone 6 is more elegant, rounded and streamlined than the iPhone SE however, so for those that don't mind a slightly larger smartphone and those happy to pay a little more, you'll find yourself with a beautiful device opting for the iPhone 6.

WHY BUY?

The iPhone 6 is the perfect iPhone for those who want a stunning device that looks like the latest iPhone but doesn't have all the latest features. Its size won't suit everyone, as while Samsung and LG have had large phones for years, Apple only caught up here last year and some fans will take a little longer to adjust, or decide they don't want to adjust at all.

If you want a premium, powerful and slightly larger smartphone running iOS, but you don't want to pay the price of the newest, the iPhone 6 is your one.

PRICE: From £459

AppleiPhone 6S

The Apple iPhone 6S is the successor to the iPhone 6 with an almost identical design but it brings in more powerful specs and a few additional features, making it the flagship iPhone. You'll still find a 4.7-inch display with a 1334 x 750 pixel resolution so you'll get much of the same experience as the iPhone 6, but the iPhone 6S introduces a technology called 3D Touch.

In terms of build, the iPhone 6S is ever so slightly larger and heavier than the iPhone 6 measuring 138.3 x 67.1 x 7.1mm and hitting the scales at 143g, but you get the latest A9 processor and M9 motion coprocessor, along with storage options of 16GB, 64GB or 128GB. 

It comes in four colours like the iPhone SE, including rose gold and the gold that was originally available on the iPhone 6 before the iPhone 6S was announced and the gold option on the iPhone 6 was dropped. Battery remains the same, as do many of the other features including Touch ID.

It's the camera capabilities that see one of the biggest differences between the iPhone 6 and the iPhone 6S. This flagship iPhone sports the 12-megapixel rear snapper like the iPhone SE, but it ups the front-facing snapper to 5-megapixels. There is also a feature called Live Photos on board and support for 4K video recording too, like the smaller iPhone SE. 

If you want the top-of-the-range iPhone but you aren't looking for a phablet, the 6S is the best option. It has all the latest specs and features Apple has to offer in a slim, premium design.

WHY BUY?

The iPhone 6S is the flagship iPhone at a more manageable size than the Plus models.

It's the model for those that are after the latest and greatest specs, most recent features and more colour choices but with a 4.7-inch display rather than a 5.5-inch.

PRICE: From £539

AmazoniPhone 6 plus

The iPhone 6 Plus is one of the big friendly giants of the iPhone world. If you have even considered the iPhone SE, chances are you won't even be looking at the iPhone 6 Plus, but for those after an Apple phablet - this is one of two options.

The iPhone 6 Plus has a 5.5-inch display with a 1920 x 1080 resolution that delivers a pixel density of 401ppi so slightly crisper and sharper than the smaller iPhones available. Of course, a larger screen means a larger and heavier body so you can expect a 158.1 x 77.8 x 7.1mm footprint, and a weight of 172g for the iPhone 6 Plus. Let's just say it isn't as pocket-friendly as the iPhone SE, iPhone 6 or iPhone 6S.

Aside from physical size and display however, the iPhone 6 Plus is virtually identical in specs to the iPhone 6 meaning the same 8-megapixel rear iSight camera with the addition of optical image stabilisation for the iPhone 6 Plus, NFC capability for Apple Pay and the A8 processor.

The same colour options as the iPhone 6 apply and the same storage options as both the iPhone 6 and iPhone SE so you can choose between 16GB and 64GB but the battery capacity is larger on the iPhone 6 Plus, as you might expect. Apple claims it will offer up to 24 hours of talk time in comparison to the 14 hours of the iPhone SE and iPhone 6.

The more you get, the more it costs however. The iPhone 6 Plus is one of the more expensive iPhone options, starting at the same price as the iPhone 6S. You need to be both happy to splash the cash, as well as happy to have a smartphone that covers the majority of your head when taking calls if the iPhone 6 Plus is going to be the one for you.

WHY BUY?

The iPhone 6 Plus is the perfect iPhone for those who want the great design aesthetics of the iPhone 6 but on a larger scale. It's for those that want iOS on a phablet but aren't too fussed about the latest and greatest specs.

It's one of the two bigger iPhones but it doesn't have every feature Apple offers so if you're down with the size, but you're looking to spend a little less than the price of the iPhone 6S Plus, the iPhone 6 Plus could be the one for you.

PRICE: From £539

AmazoniPhone 6S plus

The Apple iPhone 6S Plus is the biggest, heaviest and most expensive iPhone available. It's the second of the two big friendly giants in the iPhone world but it packs in slightly upgraded specs in comparison to its predecessor.

The iPhone 6S Plus is very similar to the iPhone 6S in terms of specs and it is almost identical to the iPhone 6 Plus in terms of design, like the iPhone 6S is to the iPhone 6. It's a little larger at 158.2 x 77.9 x 7.3mm and a little heavier at 192g but like the iPhone 6S, it packs in new tech here and there.

The display remains at 5.5-inches with a Full HD resolution for a pixel density of 401ppi, but like the iPhone 6S, the iPhone 6S Plus introduces 3D Touch, as well as a new camera.

There is a 12-megapixel snapper on the rear and a 5-megapixel snapper on the front along with all the same features of the iPhone 6S including Live Photos and 4K video recording. You will also find optical image stabilisation on the iPhone 6S Plus, like the iPhone 6 Plus, which isn't available on the iPhone 6 or iPhone 6S.

The battery remains the same as the iPhone 6 Plus, but you will get the option of a 128GB storage model for the iPhone 6S Plus, as well as the addition of rose gold and gold colour options.

WHY BUY?

If you want the biggest iPhone available with the latest and greatest specs, the iPhone 6S Plus is the one for you.

It packs in the more powerful specs like the iPhone 6S, but it does so in a bigger format so if 4.7-inches isn't quite big enough for you and budget isn't an option, the iPhone 6S Plus is the one you'll want. 

PRICE: From £619
