Best flagship phones 2021 - buyer’s guide
Last updated: November 5, 2021 (Changelog)
If you are after the very best on the smartphone market, you've come to the right section of this buyer's guide.
The highest of high-end phones are in this category. The latest Galaxy and iPhone are the default choices at this level, but big names out of China have their own takes too, of course. Both Xiaomi and Oppo can offer you no-compromise handsets with build and features to match or even beat Apple and Samsung. Foldables can be found here too - the Samsung Galaxy Z Fold3 and the Huawei Mate X2 may not be for everyone, but if you've got the money, they're well worth a try.
Apple iPhone 13 Pro Max
- 'Best iPhone ever'
- Robust build - Steel frame, Ceramic Shield, IP68 and then some
- Most potent chipset on the market
- Large 120Hz Dolby Vision OLED, even if notched
- Four flagship 12MP cameras, LiDAR scanner
- Top-notch battery life
- Class-leading speaker quality
- At least 5 years of firmware updates
- No charger, no headphones in the box
- Not the fastest to charge
- Apple iOS is not for everyone
The iPhone 13 Pro Max is currently Apple's best iPhone. It finally brings some long-overdue features like an ProMotion 120Hz display, a smaller notch, and a more prominent camera upgrade with a larger sensor for the main camera, a 3x telephoto, and an improved ultrawide camera with macro mode.
The Apple iPhone 13 Pro Max offers amazing dust and water resistance, plus its Ceramic Shield is incredibly crack proof. Of course, the latest iPhone is unmatched when it comes to performance. If you are an iPhone type of person, the 13 Pro Max is a no-brainer. If you are after the best flagship - that's also this iPhone 13 Pro Max but you should be willing to give Apple iOS a chance. It's not bad, it's just different.
All of these apply to the regular Pro, in fact. It's up to you to decide which size suits you best. No matter the hardware differences, you will still get the same experience. Got to love Apple for that.Read full review
Google Pixel 6 Pro
- Beautiful new design, IP68, GG Victus
- Google's own Tensor chip
- Large 120Hz OLED, HDR10+, bright
- Three flagship cameras with top-notch photo and video quality
- Class-leading speaker quality
- Fast firmware updates
- No charger and not the fastest to charge
- Average battery life
- HDR+ is overly aggressive, color inconsistencies
- Limited availability
The Pixel 6 Pro is finally here and has a lot of new features we liked instantly. The new design is cool, the 120Hz OLED screen is great, and the phone has one of the fastest chips on the market.
The Pixels are known for their cameras and the Pixel 6 Pro delivers handsomely - it has a triple rear camera with long-range 4X zoom. The photo and video quality has been improved significantly and there are even some new tricks thanks to the Tensor chip. Finally, since it's a Pixel, you can expect on-time Android updates
It's not all sunshine and roses for this Pixel, though. Its battery life is uninspiring, the charging isn't that fast, and the HDR+ mode won't be everyone's cup of tea. There are also the color inconsistencies between the primary and the ultrawide cameras. Those aren't deal breakers per se, but they are enough to raise a few concerns before purchasing this Pixel. If it is sold in your country, that is.Read full review
Samsung Galaxy S21 Ultra 5G
- The best OLED screen, 1000+nits, 1440p, 120Hz, HDR10+, S-Pen support
- Outstanding battery life, fast to top-up the 5,000mAh battery.
- Overall great camera performance across the board, long zoom capability
- Somewhat bulky and slippery, rear camera bump can be an eye sore
- Scant retail package
- Regional chipset divide could bother some, lack of microSD slot too
The Galaxy S21 Ultra gathers all the cutting edge tech Samsung can offer to the public so far, short of a foldable screen. It's only natural that it has a superb display with all the bells and whistles, this time including S Pen support. Battery life is excellent, the latest-gen fingerprint reader is great, the stereo speakers are loud and clear.
Then there are the cameras. A quad setup means you have two teles on this Galaxy Ultra going all the way up to 10x natively. On the ultrawide end there are developments too – the addition of autofocus has left us with one less thing to complain about and made it competitive for a change. And the main unit is a new and improved take on the 108MP Nonapixel concept with advancements in HDR, low light and autofocus performance. The selfie camera continues along the same lines, delivering praise-worthy results.
The continued regional divide that leaves the bulk of the world with what some perceive as the inferior Exynos chipset is hardly ideal, though the gap between it and the Snapdragon have gotten so small as to be irrelevant. The barebones retail package is also not our favorite trend, even if it's being marketed as environmentally friendly. The disappearance of the microSD slot for this generations is hardly ideal either. Ultimately though, these are small enough as to be largely immaterial and Galaxy S21 Ultra is one of the best flagships and the best Android smartphone.Read full review
Xiaomi Mi 11 Ultra
- Attractive curved-screen design, ceramic back
- Thoroughly impressive main display
- Rear display has great potential
- Blazing-fast charging, good endurance for the class
- Industry-leading photo and video quality across the board
- Heavy and bulky, camera bump is hardly a looker
- Under-utilized rear display
- A tendency to overheat under stress testing
The Xiaomi Mi 11 Ultra won us over with its camera chops – a good thing since the unsightly camera bump needed to be justified. The Mi doesn't stop there, however, and gets high marks in all arears including display, battery, performance, and build.
Its really the camera system that's the Mi 11 Ultra's key selling point. The biggest sensor on a smartphone is used for the main unit, and there's another couple of large sensors for the ultrawide and the 5x periscope tele, all three of them delivering excellent image and video quality. A unique feature is the rear-facing display – letting you frame rear-camera selfies like no other phone (well, except the Zenfones), though you can't use it for video which is a minor letdown.
The display, meanwhile, is the best panel you can find outside of a Galaxy Ultra and this one is as good as them. Battery life is above average for the segment, only second to the S21 Ultra's, but the charging speed on the Mi is up there with the best. The MIUI and SD888 make for a fluid and polished user experience and all of that is wrapped in a fancier-than-most glass-ceramic body.
That body is quite heavy though, and the Mi 11 Ultra's dimensions may not be everyone's cup of tea. We'd struggle to find a person to call the camera bump appealing either. But those pictures, though.Read full review
Oppo Find X3 Pro
- Exquisite design with mirror-like back and sweeping lines around the camera
- Some of the fastest wired and wireless charging
- Outstanding photo and video quality, day and night
- Intriguing one of a kind microscope camera
- Lowest battery life in the class
- The telephoto camera needs OIS, also more reach (it's just 2x)
- Limited market availability
Another year, another great Find – the Find X3 Pro continues a lineage of compelling flagship Oppos in the high-end segment. This one's unique bit is a microscope camera with a ring light on the back – alongside excellent hardware and performance in most areas, of course.
There are two main points that might make you think twice about this one. The more important one is battery life – it's not bad for a top-tier handset, but virtually all competitors have it beat. The other is the telephoto – at just 2x zoom it's lacking in reach in a world of 5x and even 10x periscopes.
If you prefer taking pictures of tiny things over distant things, the Find's microscope is unrivaled, however. Plus, the other two cameras will hardly leave you wanting, no matter the circumstances. And for all it's lacking in endurance, the Oppo makes up for in charging speed. And in contrast to our favorite cameraphone for the time being, the Mi 11 Ultra, the Find X3 Pro's camera bump is much easier on the eyes.Read full review
vivo X70 Pro+
- 256GB 8GB RAM $ 902.86
- High-quality build, premium looks, IP68, rich retail bundle
- Large 120Hz QHD LTPO AMOLED
- Class-leading performance
- Great photo quality across the board
- Excellent video stabilization
- Loud stereo speakers
- India exclusive
- Funtouch OS launcher is not everyone's favorite
It may look like a relatively unlikely entrant on this list, but the vivo X70 Pro+ addition here is well deserved. The few notable X60 Pro+ omissions are now fixed and the new X70 Pro+ features IP68-rated protection, a QHD 120Hz display, and stereo speakers.
The X70 Pro+ stands out from the crowd in a few good ways. It packs the latest SD888+ chip, then there is the video stabilization that's a notch better than the rest – that's on top of an overall great and versatile camera experience, of course.
Just like the X60 Pro+, the X70 Pro+ seems to be India-exclusive, too, and that's the most notable con we could think of.SPECS
Samsung Galaxy Z Fold3 5G
- Truly innovative form factor, smaller hinge gap, S-Pen support
- Hardware offers unique usability potential, the software is there to unlock it
- Great 120Hz AMOLED screens
- Outstanding speakers
- Under-display camera
- Solid all-round camera system, complete with unique selfie capabilities
- Gap is still present and even the new tougher display protector is still soft and susceptible to damage.
- The Snapdragon 888 chipset is a bit thermally-constrained and underperforms slightly
- Disappointing battery life, ships without a charger
- Not quite flagship-grade camera quality
The new waterproofed Galaxy Z Fold3 is a handset you can get if a regular bar doesn't cut it anymore. It has improved hinge and offers ingress protection, plus it introduces an under-display selfe camera. Truly innovative, some may say.
Samsung's third generation of phone-turns-into-tablet foldable comes with an improved build, chipset, cameras. On the software side, OneUI is there to help if you're wondering what to do with the form factor, but multi-tasking and selfie-taking are two areas elevated to a whole different level.
The camera system isn't half bad, but it's not quite a match for Samsung's non-folding top-end models - a periscope is missing, the others aren't state of the art either. The Z Fold3 battery life is quite uninspiring, though, and there is no charger inside the box. The stereo speakers are still as wonderful. Overall, Samsung's way past the proof of concept stage with this one, so it's worth a look if you're shopping with an unlimited budget.Read full review
Huawei Mate X2
- Ingenious wedge design and teardrop hinge mean no air gapwhen folded
- Impressively flat internal display in unfolded state, 90Hz refresh on both panels
- Amazing stereo speaker setup
- Versatile flagship-grade camera setup
- Availability limited to its home market
- No official HDR certification on either display
- Hinge does not provide linear motion and cannot be fixed at an arbitrary angle
- No wireless charging support
- EMUI 11 is based on Android 10, lacks Google Services and its future is uncertain
Not a mainstream option we can recommend to everyone, but the Huawei Mate X2 still deserves a spot on this list. Huawei's latest foldable solves a few issues of earlier designs and adds more polish, nudging us closer to wider adoption of the form factor. Eventually. Maybe.
Its teardrop hinge and web design help eliminate the air gap between the two halves in the folded state – a main gripe with the Galaxy Z Fold2's design. The Mate's internal crease is also minimal and two halves lay remarkably flat. On the flipside, Huawei's solution doesn't allow you to leave the phone folded at an arbitrary angle, limiting usability for some edge cases. While on the display topic, the Mate's both panels can go as high as 90Hz – the Galaxy maxes out at 120Hz on the big one (win), but can only go as high as 60Hz on the cover.
The Mate X2 features a high-end camera system too, one worthy of a flagship in the bar form factor, something Samsung couldn't fit on the Z Fold2.
Of course, there are several concessions you need to make if you opt for the Mate X2. The most important one is the lack of Google backing that's leaving you at Android 10, and the unclear future of the Huawei in-house OS doesn't help. Next to that, the missing wireless charging, no HDR support on the displays and the proprietary storage expansion solution sound like minor niggles.Read full review
