Best phone 2021: which smartphone is for you?

The Samsung Galaxy S21 Ultra from the front and back with its screen on

1. Samsung Galaxy S21 Ultra

A top tier smartphone, and it takes our best crown

Release date: January 2021 | Weight: 227g | Dimensions: 165.1 x 75.6 x 8.9 mm | OS: Android 11 | Screen size: 6.8-inch | Resolution: 1440 x 3200 | CPU: Snapdragon 888 / Exynos 2100 | RAM: 12GB / 16GB | Storage: 128GB/256GB/512GB | Battery: 5,000mAh | Rear camera: 108MP + 10MP + 10MP + 12MP | Front camera: 40MP

The best camera zoom
Mesmerizing design
Expensive at any level
No microSD card slot

The Samsung Galaxy S21 Ultra is our best smartphone in the world right now, and we think it’s a fantastic choice for you with one of the best cameras, phenomenal power, great battery life, a solid design and a whole host of other great features.

The Galaxy S21 Ultra isn’t a cheap handset, the price is high for this one, but if you’re looking for the ultimate smartphone experience in 2021 you will be hard-pressed to do better than this latest from Samsung.

It features a top 6.8-inch screen with a 120Hz adaptive refresh rate and a Quad HD resolution. This is one of the best smartphone displays on the market.

The battery life is also solid, and we found it’d often see us through a whole day from a full charge. Note the Galaxy S21 Ultra doesn’t come with a charger in the box though, so you’ll have to use your existing one or buy one separately.

Samsung’s 108MP camera on the Galaxy S21 Ultra is going to be the highlight for many, and the camera doesn’t disappoint on this phone. Like its predecessor, you can take 100x zoom photography, but it’s far improved here over the Galaxy S20 Ultra with two cameras working to do the heavy lifting.

The Samsung Galaxy S21 Ultra won’t be for everyone with its high price, but it’s the ultimate smartphone you can buy right now taking our crown for the best smartphone money can buy. Be sure to read our full review before making your final decision, but if you’re after one of the best overall smartphone experiences we believe you’ll find it here with Samsung’s latest.

2. iPhone 13 Pro / iPhone 13 Pro Max

The best iPhones

Release date: September 2021 | Weight: 204g / 240g | Dimensions: 146.7mm x 71.5mm x 7.7mm / 160.8mm x 78.1mm x 7.7mm | OS: iOS 15 | Screen size: 6.1-inch / 6.7-inch | Resolution: 1170 x 2532 / 1284 x 2778 | CPU: A15 Bionic | RAM: 6GB | Storage: 128GB/256GB/512GB/1TB | Battery: 3,095mAh / 4,352mAh | Rear camera: 12MP + 12MP + 12MP | Front camera: 12MP

Great performance
Strong battery life
Limited design changes
Notch still too large

The iPhone 13 Pro and iPhone 13 Pro Max are the best iPhones available at the time of writing, offering more power than ever before, improved cameras, 120Hz refresh rates and surprisingly good battery life.

Whether you choose the 6.1-inch iPhone 13 Pro or 6.7-inch iPhone 13 Pro Max you’re getting a sharp OLED screen with a 120Hz variable refresh rate. The continued presence of the notch is annoying, but it’s slightly smaller this time and easy to ignore, especially once you see the overall quality of the display.

Apple has outdone itself with the battery life on the iPhone 13 Pro Max, which is genuinely great, rather than just being great for an iPhone. The iPhone 13 Pro’s isn’t quite as good, but it’s still decent and an upgrade on the iPhone 12 Pro’s life.

The iPhone 13 Pro range includes the same lens types as last year, but with larger pixels and new modes, including an impressive macro mode, and a slightly less significant Cinematic mode. Between all this and their improved low light performance, these cameras are ace.

While the iPhone 13 Pro and Pro Max are the best iPhones, they’re slightly topped by the Samsung Galaxy S21 Ultra, which has a better design and a more versatile camera, but these phones come very close and are the obvious choice for iPhone fans. With a higher refresh rate than the iPhone 12 range, a new macro mode, and a smaller notch, they aren’t the biggest upgrades but they’re undeniably great.

3. OnePlus 9 Pro

A giant leap for OnePlus photography

Release date: March 2021 | Weight: 197g | Dimensions: 163.2 x 73.6 x 8.7mm | OS: Android 11 | Screen size: 6.7-inch | Resolution: 1440 x 3216 | CPU: Snapdragon 888 | RAM: 8/12GB | Storage: 128/256GB | Battery: 4,500mAh | Rear camera: 48MP + 50MP + 8MP + 2MP | Front camera: 16MP

The best OnePlus camera phone
Very powerful phone
Expensive for OnePlus
No microSD support

The OnePlus 9 Pro is a top-tier flagship phone and one that improves on the main weakness of previous OnePlus handsets – their cameras. This is a phone that can compete with the other best phones, and some may even prefer its camera to the other phones on this list.

It has a 6.7-inch screen, which will likely impress you with its ‘Fluid Display’ that sets the refresh rate to 120Hz. Not only does it make the game look better, but simply scrolling the web looks smoother. You’ll also find nice upscaling and HDR10+ here.

It doesn’t offer the absolute best battery life we’ve seen on a smartphone, but it features a 4,500mAh cell that is set to last you a full day from a single charge. It also has great fast charging and wireless charging features.

Thanks to a new Hasselblad partnership and a ‘freeform’ ultra-wide lens, designed to reduce the distortion at the edge of images, the OnePlus 9 Pro is the best OnePlus camera phone. It isn’t the absolute best camera phone, but it’s a remarkable step up from the company with a great 48MP main camera alongside an 8MP telephoto and 50MP ultrawide.

OnePlus may have focused its attention on the cameras for the OnePlus 9 Pro, but this is an overall incredible smartphone offering top-end power, a great display and most features you’d expect from any other phone you’ll find on this list.

Battery life isn’t the absolute best, and it’s remarkably expensive considering OnePlus’ history in the smartphone market but it has earned its place this high on our best smartphone list because it’s the overall package.


An iPhone 13 against a white background

4. iPhone 13

The best Apple iPhone bang for your buck

Release date: September 2021 | Weight: 174g | Dimensions: 146.7 x 71.5 x 7.7mm | OS: iOS 15 | Screen size: 6.1-inch | Resolution: 1170 x 2532 | CPU: A15 Bionic | RAM: 4GB | Storage: 128GB/256GB/512GB | Battery: Up to 19 hours | Rear camera: 12MP+12MP | Front camera: 12MP

Strong battery life
Powerful internals
Minimal design changes
No 120Hz screen

The iPhone 13 isn’t as big an upgrade as the iPhone 13 Pro, as it lacks a 120Hz refresh rate, but with oodles of power and good battery life, it’s a strong choice if you don’t have the fortune to spend.

With its 6.1-inch 1170 x 2532 OLED display, the iPhone 13 has a bright and clear screen. It doesn’t have a 120Hz refresh rate, but it does at least have a slightly smaller notch than the iPhone 12.

In our tests, the iPhone 13 reliably lasted through a day of use, but not much more. That puts it in the fairly average territory, yet it’s still an improvement on many previous iPhones here.

The iPhone 13 lacks a telephoto camera, but its main and ultra-wide performance well, with the former having larger pixels than the iPhone 12’s. With improved image stabilization too, plus some new shooting modes and features, there’s a lot to play with here, and a lot to like.

The iPhone 13 Pro / Pro Max and the Samsung Galaxy S21 range have the edge over the iPhone 13 when it comes to specs and features, but this standard iPhone model comes close to matching them, especially when it comes to battery life. And actually, it probably has slightly more power than its Android rivals.


5. Samsung Galaxy S21 / S21 Plus

Not the best of the S series, but nevertheless great

Release date: January 2021 | Weight: 169g/200g | Dimensions: 151.7 x 71.2 x 7.9 mm / 161.5 x 75.6 x 7.8 mm | OS: Android 11 | Screen size: 6.2-inch / 6.7-inch | Resolution: 1080 x 2400 | CPU: Snapdragon 888 / Exynos 2100 | RAM: 8GB | Storage: 128GB / 256GB | Battery: 4,000mAh / 4,800mAh | Rear camera: 12MP + 64MP + 12MP | Front camera: 10MP

Fantastic, versatile camera
Cheaper than the Galaxy S20
No microSD support
Screen isn’t the best

The Samsung Galaxy S21 and Samsung Galaxy S21 Plus aren’t the height of spec and prowess as their predecessors used to be – the Samsung Galaxy S20 used to sit at the top of this list – and instead Samsung’s Ultra handset is taking the limelight.

The Samsung Galaxy S21 and its bigger sibling are trying to do something differently, and both are remarkably cheaper than the Galaxy S20 range was at launch. Both still offer a phenomenal smartphone experience, and with a lower price, it’ll be a top choice for many.

Much has been said about Samsung’s switch to Full HD for the Galaxy S21, but in our testing, we didn’t notice the knockdown in resolution much unless we were testing the phone side by side with a QHD display. With a 120Hz refresh rate and great brightness, the Galaxy S21’s screen will satisfy many and if you’re after a larger option you’ll find the Plus is built for you with its 6.7-inch screen.

The battery life on the Samsung Galaxy S21 will last you a full day from a single charge, and it’s 4,000mAh cell means you’ll get a lot of usage out of the handset without having to recharge the phone. We found the S21 Plus offers a longer battery life though with its 4,800mAh cell.

The Galaxy S21s camera is much the same as the Galaxy S20, but a few software tweaks have been included from Samsung that make it just that touch better. Overall, this isn’t as phenomenal as the Galaxy S21 Ultra but for most just wanting to shoot the odd snap, this will suit you perfectly.

The Samsung Galaxy S21 will be the perfect smartphone for many with its great mix of solid spec, a great design, and the fact it’s cheaper than the Galaxy S21 Ultra as well as its predecessors.

If you own the Samsung Galaxy S20 we wouldn’t recommend buying this, but for others, this will be the perfect smartphone. If you need a slightly longer-lasting battery and a larger display, also consider the Samsung Galaxy S21 Plus (even though its specs are remarkably similar).


Xiaomi Mi 11

6. Xiaomi Mi 11

Xiaomi’s 2021 flagship

Release date: March 2021 | Weight: 196g | Dimensions: 164.3 x 74.6 x 8.6mm | OS: Android 11 | Screen size: 6.8-inch | Resolution: 1440 x 3200 | CPU: Snapdragon 888 | RAM: 8GB | Storage: 128GB/256GB | Battery: 4,600mAh | Rear camera: 108MP + 13MP + 5MP | Front camera: 20MP

Great photography modes
Fast performance
Temperamental fingerprint scanner
Weak battery life

The Xiaomi Mi 11 is the culmination of years of progress from the company, and it’s the highest we’ve ever seen a smartphone from the manufacturer sit in this list of the top phones.

You’ll get everything from a top-end processor, a phenomenal display, a power rear camera, and much more in the Xiaomi Mi 11.

There’s a 6.81-inch display on the Xiaomi Mi 11, and it has a top resolution of 1440 x 3200. This AMOLED panel is one of our favorites on smartphones right now, and it features a 120Hz refresh rate meaning gaming and more is super smooth.

The camera on the Xiaomi Mi 11 sounds great on paper, and while it may not as powerful as we had expected in real life it’s a versatile shooter with a 108MP f/1.9 main lens and a 13MP f/2.4 ultra-wide backing it up. There’s no telephoto shooter here, though.

The battery life is one of the weaker areas for the Mi 11, but it’s not atrocious and we found the phone’s 4,600mAh cell would last a full day of normal usage. If you’re expecting to use your phone considerably more, you may want to look elsewhere on this list.

The Xiaomi Mi 11 is a great alternative to the normal names you’d expect in this ranking of the very best smartphones. Battery life isn’t the best, and there’s no telephoto camera but if you’re okay with those concessions you may find the Mi 11 is built for you.

7. Google Pixel 6 / Google Pixel 6 Pro

The best phones for pure Android

Release date: October 2021 | Weight: 207g / 210g | Dimensions: 158.6 x 74.8 x 8.9mm / 163.9 x 75.9 x 8.9mm | OS: Android 12 | Screen size: 6.4-inch / 6.71-inch | Resolution: 1080 x 2400 / 1440 x 3120 | CPU: Google Tensor | RAM: 8GB / 12GB | Storage: 128GB/256GB/512GB | Battery: 4,614mAh / 5,003mAh | Rear camera: 50MP + 12MP / 50MP +48MP + 12MP | Front camera: 11.1MP / 8MP

Multitalented camera
Big and beautiful screen
Contentious design
Average battery life

The Google Pixel 6 and Pixel 6 Pro are the most exciting phones Google has launched in a long time, or arguably ever.

They both have a design that’s unlike any other phone, with a large camera visor and a three-tone color scheme, and they’re just as interesting on the inside, with a Google Tensor chipset that’s been designed and built specifically for these handsets.

Both also excel for taking photos, with a 50MP main and 12MP ultra-wide snapper – along with a 48MP telephoto camera offering 4x optical zoom in the Pixel 6 Pro’s case.

And speaking of the Pixel 6 Pro, this is a true flagship, with a 6.7-inch QHD+ 120Hz screen and 12GB of RAM. The standard Pixel 6 has slightly lesser specs, but also comes in at a temptingly affordable price, and both phones run Android 12, with Google’s vision of the software intact.

So they’re a great showcase for Android, but middling battery lives and a chipset that’s not quite a match for rivals in benchmarks stops them from ranking higher on this list.


Oppo Find X3 Pro

8. Oppo Find X3 Pro

A premium device for a premium price

Release date: March 2021 | Weight: 193g | Dimensions: 163.6 x 74 x 8.3mm | OS: Android 11 | Screen size: 6.7-inch | Resolution: 1440 x 3216 | CPU: Snapdragon 888 | RAM: 8/12GB | Storage: 256GB | Battery: 4,500mAh | Rear camera: 50MP + 13MP + 50MP + 3MP | Front camera: 32MP

Fantastic cameras
Good-looking display
Oppo’s most expensive
No periscope camera

The Oppo Find X3 Pro is a follow-up to one of 2020’s best smartphones – that’s unsurprisingly the Oppo Find X2 Pro – and this handset is the most accomplished smartphone from the manufacturer so far.

You’ll find a top display, processor, camera, and much more on the Oppo Find X3 Pro that justifies its high price tag.

The 6.7-inch display on this phone is one of the very best on the market right now. The resolution is fantastic, it’s punchy and you’ll enjoy using the screen on this device if you’re after a large phone.

The Oppo Find X3 Pro is one of the better battery life smartphones out there, and we found in our testing that it’d often last a full day of medium to high use. If you do need to recharge often, it features some top-end fast charging to make up for it.

There is some fantastic spec here making it one of the very best camera phones you can buy right now. This is where the Oppo Find X3 Pro shines through, and we found the camera was able to take colorful images with plenty of detail.

This isn’t the cheap handset you may expect from Oppo. It’s a top-end phone that’s capable of fighting against the big guns of Apple, Samsung, and OnePlus that surround it. If you’re after something different, be sure to read our review below.


The Samsung Galaxy Note 20 Ultra on a white background with its S Pen stylus sitting next to it

9. Samsung Galaxy Note 20 Ultra

This productivity powerhouse is the best phone to get stuff done on

Release date: August 2020 | Weight: 208g | Dimensions: 164.8 x 77.2 x 8.1mm | OS: Android 10 | Screen size: 6.9-inch | Resolution: 1440 x 3088 | CPU: Snapdragon 865 Plus / Exynos 990 | RAM: 12GB | Storage: 128/256/512GB | Battery: 4,500mAh | Rear camera: 108MP, 12MP, 12MP | Front camera: 10MP

Useful S Pen features
Great-looking screen
Slow charging
Huge size

Samsung’s latest Note entry is the Samsung Galaxy Note 20 Ultra, with advanced features, a great-looking screen, and special features for the S Pen stylus which comes included in the phone, that give you added versatile ways to use your device.

Sure it’s expensive, and pretty huge, and doesn’t actually have all the bells and whistles of the Galaxy S20 Ultra or Galaxy S21 Ultra. But those weaknesses are made up for with plenty of advantages.

The Galaxy Note 20 Ultra has one of the best display’s on any smartphone, with a 120Hz refresh rate (at FullHD+ resolution) and the option of QHD+ resolution (at a 60Hz refresh rate) – plus at 6.9 inches there’s plenty of space for movies, games and productivity apps.

The Samsung Galaxy Note 20 Ultra camera is… impressive. With 0.5x ultrawide, 1x regular,  5x optical, and 50x digital zoom levels, you can get closer to subjects and still get stunning shots.

If the Note 20 Ultra has a slight weak point, it’s the battery. In most of the world (basically outside North America) the handset comes with Samsung’s Exynos 990 chipset which isn’t quite as power-efficient – if you push the handset, you’ll need to recharge before the day is out.

This is a real top-end phone with top specs in every sector, so if your budget (and hand) can stretch for it, the Samsung Galaxy Note 20 Ultra is the power and productivity user’s phone of choice.


Realme GT

10. Realme GT

The first Realme phone on this list

Release date: March 2021 | Weight: 186g | Dimensions: 158.5 x 73.3 x 9.1mm | OS: Android 11 | Screen size: 6.43-inch | Resolution: 1080 x 2400 | CPU: Snapdragon 888 | RAM: 8GB | Storage: 128GB | Battery: 4,500mAh | Rear camera: 64MP + 8MP + 2MP | Front camera: 16MP

Distinctive design
One of cheapest great phones
Cameras are only okay
Software issues

Realme hasn’t ever featured on our ranking of the best smartphones, until now. This new handset from the company is its best yet, and it features top-end specs that can compete with the very best phones but at an affordable price.

The Realme GT can be difficult to find in the UK, but if you’ve got the determination you’ll likely enjoy what this can offer for an affordable price.

The 6.43-inch Super AMOLED display impressed us on the Realme GT, and while it won’t match the absolute top-tier of smartphone screen technology it’s a great choice for watching video and more.

Expect a solid day of battery life from the Realme GT, and its recharging technology is particularly impressive. If your phone is empty, you can recharge it to full in just over 30 minutes.

The camera is one of the weaker elements of the Realme GT, but bear in mind that this is a cheaper phone and we think you’ll be okay with what this handset is capable of. It features a 64MP main camera, 8MP ultra-wide, and a 2MP macro camera.

This is one of the cheapest entries in our ranking of the very best smartphones, and if you’re after something a little different to the rest of the phone market it’s worth considering. Its bold design and affordable price are two key differentiators that make the Realme GT shine.
