5G phones are everywhere now, with the latest networking tech gracing everything from Apple's iPhones even to some of the cheapest Android phones on the market.
That means that as we march through 2021, there is already a great selection of 5G-capable phones worth considering, and very little reason not to buy a 5G phone.
For a while 5G was really limited to high-end and flagship devices. That's no longer the case, with more and more mid-range and even budget handsets now supporting faster networking.
In this article we're focusing on mid-range and flagship phones, but be sure to check out our guide to cheap 5G phones if your budget is a bit lower but you still want to future-proof your next phone.
Best 5G phones 2021
Samsung Galaxy S21 Ultra - Best 5G Android
- Pros: Best camera around | Phenomenal display | Stylus support
- Cons: Bulky | Expensive
After 2020's disappointing Galaxy S20 Ultra, Samsung has finally earned the name with a follow-up that delivers almost everything you could want from a 5G Android flagship - admittedly at a price that only a few can afford, and in a form factor that will simply be too big for some.
The camera is now probably the best in any phone, with a 108Mp main shooter backed up by an ultrawide and two telephoto lenses at different zoom levels.
The expansive 6.8in display delivers both high WQHD+ resolution and adaptive refresh rate up to 120Hz, and with new S-pen stylus support it comfortably fills the productivity niche of the Galaxy Note 20 Ultra too.

Oppo Find X3 Pro - Best display
- Pros: Best screen around | Versatile camera | Unique design
- Cons: No periscope zoom | Expensive
The Oppo Find X3 Pro is a phenomenal phone by any measure. The 6.7in 10-bit 120Hz QHD+ panel is one of the best displays in any phone right now and Oppo backs it up with 65W wired and 30W wireless charging, a 4500mAh battery, and a top-tier camera that boasts 50Mp sensors on both the main and ultrawide lenses.
You’ll have to live without a periscopic zoom lens - the telephoto here is a measly 2x zoom - but Oppo instead includes a novel microlens camera capable of microscopic super-closeups. That's not the only oddity, as the design itself is utterly unique thanks to a seamlessly sloped camera module built right into the glass of the phone's body.
For pure performance the Find X3 Pro is also hard to beat, with all of the above plus a Snapdragon 888 chip, 512GB storage and 12GB RAM. You just have to be willing to pay the price, as it doesn't come cheap.

Samsung Galaxy Z Flip 3 - Best foldable
- Pros: Stunning design | Compact | Waterproof | Affordable (for a foldable)
- Cons: Average camera | Low battery life | Slow charging
If you still think that foldables are a fad, the Galaxy Z Flip 3 might be the phone to change your mind.
Thanks in part to an aggressive price cut that makes this a real rival to other flagships, the Z Flip 3 feels like a phone with few compromises.
Top specs are paired with flagship features like waterproofing and wireless charging, and the new design is second-to-none.
The camera is average - not bad, but certainly nothing special - and battery life is a letdown, but these are the only reasons not to opt for this over a traditional slab phone.

iPhone 13 Pro - Best 5G iPhone
- Pros: 120Hz display | Great camera | Long-term software support | Excellent battery
- Cons: Slow charging | Notch | Worse value than most Androids
Apple is now on its second generation of 5G iPhones, and this time around it's the Pro model that's our top pick.
It's the first iPhone to support a 120Hz display - lone overdue - in the 6.1in form factor that suits most people best, though the larger 13 Pro Max is available too if you prefer a bigger phone.
The triple camera has had an overhaul from last year, and while it still lags behind some Android rivals - especially when it comes to HDR - this is certainly among the best cameras in any phone today, especially when it comes to video.
Battery life has also had an upgrade, and it finally doesn't feel like a drawback - this is as long-lasting as any flagship out there, though the charging is still slow.

Xiaomi Mi 11 - Best value flagship
- Pros: Fast wired & wireless charging | Strong specs | Great value
- Cons: No zoom camera | Big
The Xiaomi Mi 11 is a rock-solid performer thanks to the Qualcomm Snapdragon 888 chipset with integrated 5G at its heart, which comes paired with 8GB RAM and plenty of storage.
Throw in a WQHD+ 120Hz AMOLED display (quad-curved, no less), 108Mp rear camera, and 55W fast-charging paired with 50W wireless charging, and you can see that the Mi 11 won't be beaten for specs at its price.
There are minor downsides: you won't get an IP rating, there's no telephoto camera, and Xiaomi's MIUI software still has room for improvement. But if pure performance is what you're looking for, then look no further.
There's also the more expensive Mi 11 Ultra, which upgrades to faster charging and a more powerful camera, but is much bigger - or the Mi 11 Lite 5G, which is about half the price and at the time of writing is the thinnest 5G phone you can buy.

Samsung Galaxy S21 - Best Android all-rounder
- Pros: Strong camera | Beautiful design | Compact size
- Cons: Plastic body | Worse value than rivals | Slow charging
Samsung takes the same balancing act that it struck with last year's Galaxy S20 and updates the hardware.
As a result, you get strong performance, a fresh new design, better battery life, the latest Android 11 (dressed in Samsung's own One UI 3.1, at launch) and integrated 5G.
Best of all, all this comes in a more affordable package than its predecessor - though if you're happy to spend a little more, there's always the larger S21 Plus.

OnePlus Nord 2 - Best mid-range
- Pros: Phenomenal value | Glass body | Fast charging
- Cons: Only 90Hz display | No wireless charging
OnePlus's second proper Nord phone is a worthy follow-up, powered by a custom version of MediaTek's 5G-capable Dimensity 1200 chipset.
The Nord 2 also totes a 90Hz AMOLED display, a great primary 50Mp main camera, and nippy 65W fast charging.
Software-wise, the company's OxygenOS user experience is also a major highlight - bringing responsive interactivity and a clean interface to the table that lends itself to the phone's powerful, premium feel.
OnePlus has also recently launched the Nord CE 5G, which takes most of these great specs but wraps them in a plastic body - with a few other key downgrades elsewhere. Overall we prefer the Nord 2, but the CE 5G is well worth a look if you're on a tighter budget.

Realme GT - Best 5G flagship killer
- Pros: Flagship specs | Mid-range price | Yellow leather design
- Cons: No wireless charging | Basic camera
The Realme GT is the 2021 flagship killer that the OnePlus 9 should have been.
Top specs - a Snapdragon 888 5G, 65W charging, and 120Hz AMOLED display - are encased in a phenomenal yellow vegan leather racing striped design (skip the two boring glass models) that ensures the Realme GT looks as fast as it is.
You won't get wireless charging or a waterproof rating, and the camera is a little basic, but for performance per pound there's none better right now.

Google Pixel 5 - Most compact
- Pros: Pixel camera | Google's best software | Compact & comfortable
- Cons: Under-powered processor | Bland design
Google's first 5G flagship walks a different path to its predecessors, showcasing Android 11 to the best of its abilities but also shedding the more experimental features of previous generations and opting for more conservative hardware at the same time.
Its clean design and user experience are supported by a set of superb - and now more feature-rich - cameras, as well as an incredibly compact design and battery life that's actually usable.

Asus ROG Phone 5 - Best for 5G gaming
- Pros: Incredible specs | 144Hz display | Loads of accessories
- Cons: Big & heavy | Limited camera | Gamer aesthetic
The Asus ROG Phone 5 offers one of the best mobile gaming experiences around, complete with built-in triggers, a gorgeous 144Hz AMOLED display with impressive touch response times, impressive audio chops and incredible power under the hood in the form of the Snapdragon 888 and up to 16GB of RAM.
There are plenty of accessories available, from the Switch-like Kunai 5 controllers to the AeroActive Cooler 5 to keep your phone cool during extended gameplay sessions. The software is top-notch too, offering granular per-game performance tweaks alongside system-wide performance modes.
However, while the large display means it’s great for gaming, some may find it too tall to use effectively one-handed, plus, at 238g, it’s much heavier than most flagships in 2021 – and it’s noticeable when you pick it up too.

The biggest phone we haven't mentioned above (almost literally) is the Galaxy S21 Plus. It's essentially the same as the regular S21 apart from its expanded screen size - and a bigger battery to come with it. Buy it if the S21 appeals, but you don't want to settle for a smaller form factor.
There's also always the Note 20 Ultra - a great phone for productivity that's simply been supplanted by the more recent S21 Ultra. You should still consider the Note version if you find a good price though, or if the included S-Pen appeals enough, as while it's compatible with the S21 Ultra it's sold separately and also doesn't slot directly into the phone.
We also haven't included either the OnePlus 9 or OnePlus 9 Pro, and have instead included the cheaper OnePlus Nord. We were disappointed with both the design and the performance of the 2021 OnePlus flagships, especially the much-hyped Hasselblad camera, and so we don't recommend you buy them - you're better off with rival phones from other brands, or OnePlus's own 8T or 8 Pro from 2020.
Then there's the iPhone variants. Every iPhone 13 model offers 5G support, but we've only mentioned the 13 Pro in our chart. Check out the iPhone 13 if you want a cheaper option, the 13 Mini if you like the 13 but want a smaller display, or the 13 Pro Max if you want a bigger version of the Pro.
Plus, remember that every phone in the iPhone 12 series supports 5G too - and are now available for a little less.
5G phone buying advice
Getting a 5G phone is only one piece of the puzzle. To actually take advantage of this latest generation of cellular connectivity you need to:
- Have a 5G-capable phone
- Subscribe to a network that offers 5G connectivity
- Pay for a plan that includes 5G connectivity
- Be in an area with good 5G coverage
Before you splash out on a 5G phone, it's worth checking to see what the quality of 5G coverage in your area is like, noting that it varies by network. You may have to change network if you want to reap the benefits of 5G in your area, and every network offers a different set of 5G phones - though you can of course buy any of them SIM-free.

Sub-6 vs mmWave
You may have heard about two types of 5G signal: Sub-6GHz and mmWave. The good news is that for the most part you don't need to consider this too much.
Every 5G phone ships with Sub-6 support, and conveniently this is the most common standard worldwide, including the UK and Europe.
mmWave is a shorter wavelength standard that is capable of higher speeds, but with worse range. For the moment it's only widespread in the US, and as a result it tends to only be US phones that include mmWave chips - Apple supports mmWave in its US iPhone models, for example, but not elsewhere.
If you're in North America then it is worth checking if a phone supports mmWave or not, but even there you shouldn't consider it a dealbreaker. Outside the US, there's really no point considering it at all.
Why upgrade to 5G?
5G is around 20 times faster than 4G, with the potential for even better speeds in future. With 5G, you'll be able to stream video in 4K resolution without buffering and make high-resolution video calls if you so wish. There are also benefits for mobile gaming, because of 5G's lower latency. For more details on the technology, check out our 'What is 5G?' guide.
