How to choose the best smartphone for you
Finding the right smartphone for your budget can be tricky, especially when there are so many expensive contracts to sift through. To make things easier, we’ve rounded up everything you need to know about buying your perfect smartphone, as well as what you need to know about picking out a contract.
Should I buy a smartphone on contract or SIM-free?
Generally speaking, buying a phone unlocked and SIM-free is the best option, as you can use any SIM you like and sell the phone when you want to upgrade, but you do have to have the money upfront. If you can’t stomach the upfront cost, go with a contract, but work out the total cost of it over the period to make sure you aren’t getting ripped off: if you can afford a bit more upfront, you’ll most likely save over the contract’s length.
Which smartphone operating system do I need?
There are two smartphone operating systems to decide from: iOS and Android.
You’ll only find iOS on Apple’s own smartphones. Typically, iOS gets apps first and is a wonderfully slick OS. It isn’t as customisable as Android, but there’s no doubt that it’s incredibly easy to use.
Android has a much wider reach than its Apple counterpart and is found on the majority of smartphones on the market. There are many different versions of Google’s operating system available, though. Generally speaking, you’ll want a phone running Android 11 or higher, as older versions will now be outdated. Manufacturers often customise their own versions of Android, which means that the experience can differ between handsets.

What should I look for in a smartphone display?
As most smartphones are controlled entirely with their touchscreens, the size and quality of a handset’s display are very important. A larger screen will make everything easier to read and is particularly useful for web browsing, but a big display makes for a big phone that you may find harder to carry around.
A screen’s pixel density, measured in pixels per inch (ppi), will give you an idea of how clear and sharp text will appear on a screen – a smaller number of pixels stretched across a huge screen, for example, will lead to jagged edges. Screen technology can also be very important, with AMOLED screens and IPS being the two main technologies, each with their own pros and cons.
What about performance and battery life?
Most smartphones are powered by octa-core processors these days. As a general rule, the clock speed of a processor (measured in GHz) shows how fast the phone is and will give you a rough indication of how fluid the operating system feels, as well as how the phone copes with running apps and games.
READ NEXT: The best phone battery life
Alternatively, lengthy battery life is one of the biggest things you need to look for when picking up a new phone. Our battery tests help you make the right decision about the handset that’s right for you, but generally speaking the bigger the phone’s battery capacity (measured in mAh), the longer it will last on a single charge.
How much smartphone storage do I need?
Generally speaking, a minimum of 64GB of onboard storage is fine if there’s a microSD slot, but you’ll soon find the internal storage filling up quickly. With more of an emphasis on smartphone cameras in recent years, it’s likely that your Instagram snaps will be the main culprit in using up your storage so we recommend at least 64GB to get you started.
How does Expert Reviews test smartphones?
When a handset arrives for review, we test it using a number of benchmarking methods. We typically start with CPU and GPU processing, where we use the Geekbench 5 and GFXBench applications found in the Google Play Store and Apple App Store – these provide us with a set of scores which we use to compare against similarly priced rivals. A phone’s screen is tested using DisplayCAL software and a display colorimeter. This gives us an accurate reading of how good the display is at reproducing colours, as well as maximum brightness and contrast.
Next up is battery life. This is where we use our in-house video rundown test, which displays a looped video with flight mode enabled and the screen set to 170cd/m2 brightness. We simply play the video and record the timestamp when we first boot up the phone after it runs dry. A phone’s cameras are put to the test in a variety of shooting scenarios, including scenic shots, low-light and indoor photography as well as rapid video panning in a range of modes.

The best smartphones you can buy in 2023
1. Samsung Galaxy S23 Ultra: The best smartphone overall
Price when reviewed: From £1,249 l Check price at Amazon
The Samsung Galaxy S23 Ultra is a flagship smartphone of rare distinction. The most complete high-end handset the company has produced to date, it might cost you a bit more than other handsets on this list, but the S23 Ultra is the very best Android smartphone currently on the market.
Samsung’s latest big-screened beauty has received a healthy internal upgrade this year, moving from the previous Exynos 2200 to the far superior Qualcomm Snapdragon 8 Gen 2. Performance is greatly improved as a result, and battery life is significantly longer as well.
Likewise, the S23 Ultra’s cameras continue to impress, with the addition of a new 200MP main sensor (alongside a pair of telephoto lenses and an ultrawide). Samsung’s terrific S Pen stylus also returns for its second year, and while the upgrades here might be lacking compared to the previous version, it’s still a wonderfully versatile dinky doodler.
If you’re after the very best that Android can muster, then make no mistake, it doesn’t get much better than the Galaxy S23 Ultra.

Key specs – Processor: Octa-core 3.36GHz Qualcomm Snapdragon 8 Gen 2 for Galaxy; Screen: 6.8in, 3,088 x 1,440; Camera: 200MP, 10MP (10x zoom), 10MP (3x zoom), 12MP (wide); Storage: 256GB, 512GB, 1TB; Operating system: Android 13
Also consider: Samsung Galaxy S23
Not got Ultra-sized sums for one of Samsung’s latest flagships? Not to worry, the regular Galaxy S23 is just as formidable, with much less of an impact on your wallet.
It’s a significantly smaller handset than the S23 Ultra, with its 6.1in display, so it’s also better suited for tinier hands and skinnier trouser pockets. It uses the same Snapdragon 8 Gen 2 chipset as its bigger sibling, too and while its 50MP main camera might not be as headline-grabbing, it still managed to capture some truly excellent images in our tests. The real icing on the cake, of course, is the fact that it costs a huge £400 less. The S23 is truly a flagship for the frugal.
2. Xiaomi Redmi Note 11: The best budget buy
Price when reviewed: £199 | Check price at Amazon
Smartphone flagships are getting better and better, but with these top-notch innovations comes an increased cost. Paying almost four figures for the latest top-end smartphone simply isn’t doable for most consumers, but thankfully Xiaomi’s Redmi Note 11 provides a flagship experience at a vastly reduced cost.
Xiaomi’s cheapo handset has seriously reset the benchmark of what to expect from a smartphone. Equipped with a surprisingly speedy Snapdragon 680 processor, the Redmi Note 11 outperforms phones that cost twice the price, and then some. Its quadruple-camera array is also excellent for the price, as is the large 6.43in FHD+ screen with 90Hz refresh rate.
In fact, the Redmi Note 11 doesn’t really fail in any area, especially when you consider how little it costs. If you’re in the market for a new phone in and don’t have a huge amount to spend, then the Redmi Note 11 is absolutely where your wallet should be headed.

Key specs – Processor: Octa-core 2.4GHz Qualcomm Snapdragon 680; Screen: 6.43in, 2,400 x 1,080; Camera: 50MP, 8MP (wide), 2MP (macro) and 2MP (depth); Storage: 128GB, 2556GB; Operating system: Android 11
3. Google Pixel 7: Pixel perfect
Price when reviewed: £460 | Check price at Amazon
Substantially cheaper than the rest of the flagship-class handsets on this list, Google’s Pixel 7 is yet again a true Android tour de force. Not only does it vastly undercut rivals in terms of price, but it surpasses them when it comes to photographic performance. Yet again the top contender for the camera crown, the Pixel 7’s dual cameras are practically flawless, beating the competition in terms of clarity, detail and colour reproduction.
It’s also the perfect flag bearer for Android 13. There’s no better showcase of Google’s latest version of its mobile operating system, so if you’re a keen photographer, or you’re simply after the very best that Android can get, then the Pixel 7 certainly won’t disappoint.

Key specs – Processor: Octa-core 2.85GHz Google Tensor G2; Screen: 6.3in, 2,400 x 1,080; Camera: 50MP, 12MP ultrawide; Storage: 128GB, 256GB; Operating system: Android 13
Also consider: Google Pixel 7 Pro
If you have the budget and you’re happy to spend more than the regular Pixel 7, then its bigger brother is also a terrific choice. For your extra £250, you get the same camera array as the smaller model, albeit with a third 5MP telephoto unit.
The screen is also bigger (6.7in), higher resolution (3,120 x 1,440) and refreshes at 120Hz. Everything else is the same, however, so if you aren’t fussed about the extra zoom camera and fancier screen, then the regular Pixel 7 is still your best bet.

4. OnePlus 11: The best-value flagship
Price when reviewed: £729 | Check price at Amazon
If flashy features like 100x zoom and 200MP cameras don’t impress you much, OnePlus’ latest flagship may be more your speed. Trimming the fat to focus on the fundamentals, the OnePlus 11 may be lacking in the thrill factor, but it more than makes up for it in sheer value.
Performance is terrific across the board, with the top-of-the-line Snapdragon 8 Gen 2 processor keeping up with phones that cost hundreds more and the battery lasting for over 28 hours in our tests. The standout, though, is the Hasselblad-branded camera suite, with the new portrait module (essentially a 2x telephoto lens) being a particular highlight. Images are crisp and clear, with lifelike skin tones, strong lines around the focal subject and a buttery smooth bokeh effect in the background.
There are a couple of compromises, of course – the portrait camera, while good, is no replacement for a long telephoto, and the autofocus doesn’t always hit the mark – but at this price it’s hard to be too bothered by them. For a flagship smartphone that doesn’t cross the £1,000 threshold, the OnePlus 11 is your best bet.

Key specs – Processor: Octa-core 3.2GHz Snapdragon 8 Plus Gen 2; Screen: 6.7in, 3,216 x 1,440; Camera: 50MP, 48MP (ultrawide), 32MP (portrait); Storage: 128GB, 256GB; Operating system: Android 13
5. Samsung Galaxy Z Flip 5: The best folding phone
Price when reviewed: £1,049 | Check price at Amazon
Folding phones might still be getting off the ground, but the Galaxy Z Flip 5 is a non-conventional flagship worth buying. Offering peace of mind features such as IPX8-rated waterproofing, as well as a hard-wearing “Armor Aluminium” frame and a massive cover display, the Flip 5 not only looks the part, but it’s also a clumsy-proof folding phone as well. Qualcomm’s Snapdragon 8 Gen 2 powers things, providing a huge processing boost over last year’s model, and the main display’s refresh rate is a generous 120Hz, too.
Best of all, however, is that the Flip 5 is still the cheapest folding phone on the market right now. Priced the same as a regular-sized flagship, the Flip 5 is a much more tantalising proposition. Now’s the time to jump aboard the folding bandwagon if you haven’t already.

Key specs – Processor: Octa-core 3.36GHz Qualcomm Snapdragon 8 Gen 2; Screen: 6.7in, 2,640 x 1,080 (cover: 3.4in, 748 x 720); Camera: 12MP, 12MP (wide); Storage: 256GB, 512GB; Operating system: Android 13
6. Nokia C21 Plus: The best smartphone under £100
Price when reviewed: £86 | Check price at Amazon
The Nokia C21 Plus is a perfect example of not judging a phone based solely on how much (or in this case, how little) it costs. For less than £100, the Nokia C21 Plus does everything any other smartphone is capable of doing, and you can buy almost ten of these for the price of just one iPhone 13. Naturally, there are a handful of drawbacks; performance is a bit on the slow side and it only charges via Micro-USB but for the most part, the Nokia C21 Plus is a solid budget pick for those that don’t fancy spending triple figures.
You might be able to find better low-priced handsets if you’re willing to spend just a little bit more, but if your budget is limited, you can’t do much better than the Nokia C21 Plus when it comes down to sheer affordability.

Key specs – Processor: Quad-core 1.6GHz Unisoc SC9863A; Screen: 6.52in, 1,600 x 720; Camera: 13MP, 2MP (depth); Storage: 32GB; Operating system: Android 11 Go
7. Apple iPhone 14 Pro: Excessive excellence
Price when reviewed: £1,039 | Check price at Amazon
What’s so special about Apple’s latest flagship? Well, aside from its wallet-scaring configuration options, the iPhone 14 Pro represents a handful of tweaks on top of last year’s iPhone 13 Pro.
Apple’s latest A16 Bionic chipset is once more the fastest around, even surpassing the mighty performance of Snapdragon 8 Plus Gen 1-equipped Android flagships. The Always-On display with its revamped Dynamic Island notch is an absolute delight, and the huge boost to a 48MP main camera (from 12MP) with a 65% larger sensor is a major advancement in terms of photography and videography as well. It’s not the most groundbreaking of updates, but if you’re an Apple devotee that happens to be nearing the end of a 24-month contract, then it doesn’t get much better than the iPhone 14 Pro.

Key specs – Processor: Hexa-core 3.46GHz Apple A16 Bionic; Screen: 6.1in, 2,556 x 1,179; Camera: 48MP, 12MP (3x zoom), 12MP (wide); Storage: 128GB, 256GB, 512GB, 1TB; Operating system: Apple iOS 16
8. OnePlus Nord 2T 5G: Simply superb value
Price when reviewed: £369 | Check price at Amazon
Sitting at the top of OnePlus’ mid-range smartphone selection, the Nord 2T 5G is an excellent value proposition. The MediaTek Dimensity 1300 processor delivers some of the fastest speeds you can get at this price and the battery life extended beyond 23 hours in our testing. This will easily see you into a second day of moderate use, and when it runs out, the 80W fast charge can get the battery back to full in under 30 minutes.
The display doesn’t get any upgrade from the OnePlus Nord 2, but it’s still a beautiful AMOLED panel, with essentially perfect contrast and a slick 90Hz refresh rate. There are a couple of small issues with the cameras – namely, the portrait mode isn’t particularly effective and the 4K video recording lacks stabilisation – but these problems are relatively small compared to how much value the OnePlus Nord 2T offers.

Key specs – Processor: Octa-core 3GHz MediaTek Dimensity 1300; Screen: 6.43in, 2,400 x 1,080; Camera: 50MP, 8MP (ultrawide) 2MP (depth); Storage: 128GB, 256GB; Operating system: Android 12
9. Xiaomi 13: The best compact flagship
Price when reviewed: £849 | Check price at Mi
Sometimes a flagship smartphone is simply too big to handle, and it’s here where the Xiaomi 13 really comes into its own. A proper pocket-sized powerhouse, the Xiaomi 13 is as high-end as it gets, with a terrific 6.36in AMOLED display and top-notch performance courtesy of the Qualcomm Snapdragon 8 Gen 2 chip. What really sets it apart, however, is its size: at just 153 x 72 x 8mm (HWD) it’s one of the most compact flagships we’ve reviewed in recent years.
A breath of fresh air, especially if plus-sized phones aren’t really your thing, the Xiaomi 13 is undoubtedly the best smartphone the company has produced in quite some time. It addresses a host of pain points we had with the previous model, too, including the addition of IP68 waterproofing and a rather special 3.2x optical zoom camera. It really is the complete package, so if compact phones are more your style, there’s absolutely nothing better.

Key specs – Processor: Octa-core 3.2GHz Qualcomm Snapdragon 8 Gen 2; Screen: 6.36in, 2,400 x 1,080; Camera: 50MP, 10MP (zoom), 12MP (wide) Storage: 256GB Operating system: Android 13
10. iPhone SE 3 (2022): The best-value iPhone
Price when reviewed: £499 | Check price at Amazon
With the iPhone SE 3 (2022), you’re getting a heck of a lot of smartphone for not a lot of much money. It might look like a bit of a relic – it shares the same design as the 2017 iPhone 8 – but the iPhone SE 3 is Apple’s best-value handset yet. Why? Well, it’s all about what’s inside: the iPhone SE 3 (2022) uses the A15 Bionic chipset, which is the same processor shared by the pricier iPhone 13.
That means you get the same levels of performance achieved by those high-priced flagships, at just a fraction of the cost. Likewise, the single 12MP camera might seem unassuming at first but actually manages to go toe-to-toe with the iPhone 13 in terms of sheer detail capture, especially when it comes to low-light photography.
The only fly in the ointment is that the iPhone SE 3’s battery life is quite poor by modern standards. However, if you have this amount to spend and you’d rather not use a big-screened handset, then the iPhone SE 3 (2022) remains a worthy choice. It may be the cheapest iPhone, but it’s still mightily impressive.
Read our full iPhone SE 3 (2022) review for more details
Key specs – Processor: Hexa-core 3.23GHz Apple A13 Bionic; Screen: 4.7in, 1,334 x 750; Camera: 12MP; Storage: 64GB, 128GB, 256GB; Operating system: iOS 15
