Below, you’ll find some helpful posts about Apple’s iPhone. These are some of the most-read posts on KnowYourMobile. If you’re new to iPhones, or smartphones in general, have a read of these guides – they’ll help you make a more informed decision about which iPhone is right for you.

• What is The Best iPhone? – In this post we detail all of Apple’s latest iPhone releases. We have split the post up into years, so you have options for the best iPhone for 2020, the best iPhone models for 2021, and the best iPhone for 2019. We included older models because Apple’s support is exceptional, so you can buy an older model – like the iPhone XR – and still get great support and performance in 2021.
• Which iPhones Have OLED Displays – All of Apple’s new iPhone 12 range come with OLED displays. But this is a first for Apple’s iPhone. Prior to the iPhone 12, only a select few iPhones came with OLED displays. If you want to find out which, non-iPhone 12 models, have OLED displays read this post.

iPhone Size Guide – Biggest To Smallest

Below is a quick breakdown of all the iPhone models you can currently buy (we also have one for Samsung too); the newest (and best) are, of course, the iPhone 12 and iPhone 12 Mini, as well as the “flagship” iPhone 12 Pro and iPhone 12 Pro Max Models.

But don’t go thinking you need to rock an iPhone flagship to get killer performance. I tend to buy older iPhone flagships because they’re cheaper (and I’ve been doing this for years). And if you’re interested in how Apple’s iPhone has developed over the years, check out our MEGA LIST that compares the specs of every iPhone ever released.

Below is a quick breakdown of each iPhone model, from biggest to smallest:

• iPhone 12 Pro Max: The new iPhone 12 Pro Max is the biggest iPhone Apple has ever released. It has a 6.7in OLED display and the following dimensions: 160.8 x 78.1 x 7.4 mm. This makes it not only the biggest iPhone in the iPhone 12 lineup, but also in terms of Apple’s entire iPhone release history.
• iPhone 12 & iPhone 12 Pro – Apple’s iPhone 12 (the phone that replaces the iPhone 11) keeps the same display size as before: 6.1in, though this time it uses an OLED panel. The iPhone 12 Pro is slightly larger than the iPhone 11 Pro with its 6.1in OLED panel (the iPhone 11 Pro had a 5.8in OLED panel).
• iPhone XS Max/iPhone 11 Pro Max – The iPhone XS Max is the biggest and most expensive iPhone you can currently buy. It has a 6.5in OLED display with a resolution of 2688 s 1242 pixels. This is the highest resolution panel Apple has ever used on an iPhone. And because it’s OLED, the display quality is outstanding. Blacks look amazing and whites are brilliant. OLED also uses less power than LCD, so it’s also more power-efficient.
• iPhone XR/iPhone 11 – The iPhone XR is Apple’s best-selling phone. And the reason for this is simple: it offers the most value for money. It features a large 6.1in LCD 1792 x 828 pixels that look great in all conditions. It’s not as good as the iPhone XS Max’s OLED panel. But it is still a solid performer where it counts. The key USP of the iPhone XR is its price; you get iPhone XS specs for $300 less with the only real concession being that it lacks an OLED panel.
• iPhone XS/iPhone X/iPhone 11 Pro – The iPhone X was Apple’s first OLED iPhone. The iPhone XS followed it 12 months later, keeping much the same design and the same display technology. The iPhone X/iPhone XS has a 5.8in OLED display with a resolution of 1125 x 2436 pixels. The quality of this panel is exceptional. Like the iPhone XS Max’s display, the iPhone X/iPhone XS display is a brilliant performer in all conditions. If you want the best iPhone display just on a smaller phone, the iPhone X/iPhone XS is the one to go for.
• iPhone 12 Mini – The iPhone 12 Mini is the smallest iPhone Apple has released in many generations. The iPhone 12 Mini has a 5.4in OLED display, making it smaller than the iPhone X, the iPhone XR, the iPhone XS, and the iPhone 11 Pro. The exact dimensions for the iPhone 12 Mini are as follows: 131.5 x 64.2 x 7.4 mm.
• iPhone 7 Plus/iPhone 8 Plus – The iPhone 7 Plus and iPhone 8 Plus look the same. The only difference between them is to do with the camera and the internal specs. In the hand and with respect to performance, there’s not much to separate these two phones. Both have a 5.5in 1080p LCD display and while this isn’t as good as OLED, it is still a very good display. And the really cool thing about Apple’s older flagship models is that you can now buy them for hardly any money at all.
• iPhone SE (2020) – The iPhone SE (2020) launched in April 2020 and is based on the iPhone 8’s design. It has a 4.7-inch True Tone display and its dimensions are 67.3 x 138.4 x 7.3mm, 148 grams. The iPhone SE (2020) runs on the same chipset as Apple’s iPhone 11, the A13 Bionic. It also features the same camera from the iPhone XR.
• iPhone 7/iPhone 8 – The iPhone 7 and iPhone 8 use a 4.7in LCD display with a 720p resolution. Apple stuck with this size for a few generations of its iPhone – the iPhone 6, iPhone 6s, iPhone 7, and iPhone 8. Most people that have iPhones, have one of those phones. Therefore, Apple’s 4.7in LCD 720p display is probably the most used iPhone display on the planet right now.
• iPhone 5/iPhone SE – The iPhone 5 and iPhone SE use a 4in LCD 720p display. The iPhone 5 was the last iPhone to use a 4in display. Apple released the iPhone 6 and moved to larger panels. Not everybody was happy about this, so Apple released the iPhone SE for the millions of iPhone users that wanted an iPhone with a 4in display. The 4in iPhone form factor is now officially dead. The smallest iPhone display on the market now is 4.7in on the iPhone 8. If you want a 4in iPhone, you’ll have to go to Amazon and pick yourself up an iPhone SE.
• iPhone 4/iPhone 4s – Apple’s iPhone 4 and iPhone 4s, like the original iPhones, use a 3.5in LCD 720p display. By today’s standards, the iPhone 4/4s’ display looks positively ridiculous; it’s just so small. I dug an old iPhone 4s out of one of my drawers the other day and I couldn’t believe just how small it was! Even when compared to the iPhone 5, it looks kind of silly. And the iPhone 5 is only 0.5in bigger than the iPhone 4/iPhone 4s.

Apple will also release four new iPhone 12 models in 2020 as well – one more than it did in 2019. This is what the iPhone 12 range will look like (with respect to display size):

• iPhone 12 (5.4in)
• iPhone 12 (6.1in)
• iPhone 12 Pro (6.1in)
• iPhone 12 Pro Max (6.7in)

All of Apple’s iPhone 12 models run 5G too; so you’ll be able to connect to the fastest, next-generation mobile data.

What iPhone is The Biggest?

The biggest iPhone you can buy right now is the iPhone 12 Pro Max; it has a 6.7in OLED display, the biggest ever fitted to an iPhone, and it measures in at 160.8 x 78.1 x 7.4 mm, making it the largest iPhone Apple has produced since the launch of the iPhone X.

However, the biggest iPhone overall, by sheer size, is the iPhone 8 Plus. Because it has a home button and large bezels at the top and bottom, it is both wider and taller than the iPhone 12 Pro Max.

Apple’s biggest iPhone is always its Plus model (on earlier models), Max, or Pro Max models on its more modern iPhone releases. For instance, the biggest iPhone in 2019 was the iPhone 11 Pro Max. In 2018, the biggest iPhone was the iPhone XS Max. And in 2020, the biggest iPhone will be the iPhone 12 Pro Max which has a 6.7in OLED display. 

This will remain the general rule of thumb going forwards until Apple changes how it brands its iPhone. Interestingly, we could see a return on the “plus” branding in 2021 with the release of the iPhone SE Plus which will replace the now-discontinued iPhone 8 Plus.

Apple’s entry-level iPhones for the last couple of years have also been fairly large too; the iPhone XR has a 6.1in LCD screen size and so too does the iPhone 11, again, this phone uses LCD instead of OLED which is currently reserved for Apple’s more expensive Pro and Pro Max models.

What’s really cool about the iPhone 12 range is that they all use OLED screens – even the entry-level models and the iPhone 12 Mini.

Why iPhones Are Getting Bigger

Did You Know You Could Save 40% on iPhones With This One Simple Trick? Read The Guide To Find Out… 

Phones have got bigger and bigger during the last several years. The reason? Media. Things like Instagram, YouTube, Netflix, and the web have evolved how people use and interact with their phones. In order to make the most of images and videos, you need a large, high-resolution display. Phones are used more for multimedia consumption than making and sending calls. This is the #1 reason why they’re getting bigger.

Apple was, arguably, late to the party. It didn’t start embracing larger displays until the release of the iPhone 6 in 2014. Since then, it has doubled down on larger, higher-resolution displays. The iPhone 12 Max Pro has the biggest display Apple has ever created.

In 2020, all iPhone models (inside the iPhone 12 range) will feature OLED displays. You also have the most choice with respect to size with the iPhone 12 too – it comes in three distinct screen sizes: 5.4in, 6.1in, and 6.7in.
