How we test smartphones
We thoroughly test every phone that comes into our labs, with a number of benchmarking methods. We typically start with CPU and GPU processing, using the Geekbench 5 and GFXBench applications found in the Google Play Store and Apple App Store; these provide us with a set of standardised scores which we use to compare rival handsets.
Each phone’s screen is then tested using DisplayCAL software and a display colorimeter. This gives us a precise reading of the screen’s maximum brightness and contrast, and how good it is at reproducing colours; again, we use this to objectively identify which phones have the best displays.
Next up is battery life. Here we use our in-house video rundown test, which displays a looped video with flight mode enabled and the screen set to a standard brightness of 170cd/m2 – and times how long it takes the battery to go from full to shutdown.
Finally, each phone’s cameras are put to the test in a variety of shooting scenarios, including scenic shots, low-light and indoor photography, plus rapid video panning in a range of modes.
We’ve been reviewing tech for over two decades now, and in that time, we’ve put more than 600 phones and tablets through our stringent testing process, delivering in-depth expert assessments based on facts and data.
Independence is at the heart of our approach and recommendations cannot be bought. If a popular brand delivers an unexpected dud, we’re going to tell you about it. As such, you can be sure that every product on this page has passed our high standards and has earned its recommendation based on merit.
The best smartphones you can buy in 2025
1. Samsung Galaxy S25 Ultra: Best smartphone overall
Price when reviewed: £999 | Check price at John Lewis
- Great for… incredible performance and far-reaching telephoto cameras
- Not so great for… very expensive and rivals have brighter displays
From the luxurious titanium build to the pair of telephoto cameras to the class-leading performance, the Samsung Galaxy S25 Ultra is the top-tier of smartphones. Its Snapdragon 8 Elite for Galaxy chipset delivered the fastest CPU performance scores we’ve ever recorded, it can handle 3D gaming at a steady 120fps and it proved to be one of the longest-lasting phones around in our battery life tests.
The four (!) rear cameras offer a staggering level of versatility, with the two telephoto cameras in particular offering the best zoom photography of any flagship phone we’ve tried, with greater detail retention and less over-sharpening at the maximum 100x zoom. Software is excellent, too, with seven years of updates promised and Samsung’s increasingly useful suite of Galaxy AI features.
The display, while crisp and fluid, isn’t the brightest we’ve tested, and the price tag is a rather tough pill to swallow, but if you want the best that smartphones have to offer, the Samsung Galaxy S25 Ultra is the absolute pinnacle.

Key specs – Processor: 4.47GHz Qualcomm Snapdragon 8 Elite for Galaxy; RAM: 12GB, 16GB; Display: 6.9in, 3,120 x 1,440; Storage: 256GB, 512GB, 1TB; Cameras: 200MP, 50MP (5x telephoto), 10MP (3x telephoto), 50MP (wide); Operating system: Android 15; Weight: 218g
2. Motorola Moto G55 5G: Best budget smartphone
Price when reviewed: £147 | Check price at Amazon
- Great for… performance and battery life
- Not so great for… software support and mobile gaming
The Motorola Moto G55 5G steps in to take its predecessor’s place as our favourite budget phone overall. The processor has been upgraded and yielded improved CPU performance during testing, while battery life and charging speed also get a boost, with a full charge now taking just over an hour.
The display isn’t quite as colour-accurate as before but the peak brightness is much better. The main camera remains unchanged but is still a great shooter, delivering plenty of detail in good lighting, and it’s joined by a more useful ultrawide lens this time around.
The CPU improvements aren’t matched on the GPU side of things, so you still won’t want to play anything more complex than Candy Crush, and software support is once again limited to a single year. Even still, the value for money offered by the Motorola Moto G55 5G more than makes up for its minor shortcomings.

Key specs – Processor: 2.5GHz MediaTek Dimensity 7025; RAM: 8GB; Display: 6.49in, 2,400 x 1,080; Storage: 256GB; Cameras: 50MP, 8MP (wide); Operating system: Android 14; Weight: 179g
3. Apple iPhone 17 Pro: Best iPhone
Price when reviewed: £1,099 | Check price at John Lewis
- Great for… pocket powerhouse and excellent cameras
- Not so great for… ugly new design and only a 4x telephoto zoom
The iPhone 17 Pro is the sweet spot of Apple handsets, getting you all the power and camera quality of the Pro Max in a more affordable and pocketable package.
The A19 Pro chipset delivered some of the best CPU speeds we’ve ever seen in our testing and battery life impressed, too: the iPhone 17 Pro lasted for over 31 hours in our standard video rundown, which again ranks among the longest lasting phones we’ve ever tested.
All three rear cameras are now 48-megapixel sensors and deliver crisp, impeccably lit shots with beautiful dynamic range and punchy colours. The telephoto lens only offers 4x optical zooms – whereas most rivals offer 5x – and the new design feels like a downgrade. Even still, this is easily the best iPhone yet, and the ideal pick for Apple fans.

Key specs – Processor: 4.26GHz Apple A19 Pro; RAM: 12GB; Display: 6.3in, 2,622 x 1,206; Storage: 256GB, 512GB, 1TB; Cameras: 48MP, 48MP (4x telephoto), 48MP (wide); Operating system: iOS 26; Weight: 206g
4. OnePlus Nord 5: Best smartphone battery life
Price when reviewed: £349 | Check price at Amazon
- Great for… class-leading battery life and gorgeous 144Hz display
- Not so great for… only four OS updates and mediocre ultrawide camera
The OnePlus Nord 5 delivered the best battery life that we’ve ever recorded, lasting for a phenomenal 36 hours in our standard looping video test. Even more impressive is that it surpasses phones that cost two or three times as much.
Beyond that, the Nord 5 also impressed in our performance testing, delivering some of the fastest speeds in its class and managing to hit over 80fps in the gaming benchmarks. The display is gorgeous, too, with a fluid 144Hz refresh rate and excellent colour accuracy.
The 8-megapixel ultrawide camera is fairly weak on the detail front and the four years of OS updates is less than you can get from other phones around this price. Even still, the OnePlus Nord 5 is a stamina champion and the ideal choice for those who are seeking the absolute best battery life from their next smartphone.

Key specs – Processor: 3.0GHz Qualcomm Snapdragon 8s Gen 3; RAM: 8GB, 12GB; Display: 6.83in, 2,800 x 1,272; Storage: 256GB, 512GB; Cameras: 50MP, 8MP (wide); Operating system: Android 15; Weight: 211g
5. Google Pixel 10 Pro: Best smartphone cameras
Price when reviewed: £999 | Check price at John Lewis
- Great for… outstanding cameras and magnetic wireless charging
- Not so great for… middling battery life and not the fastest CPU
Google phones regularly top our camera rankings and this year, the Pixel 10 Pro is the best of the bunch. The three rear cameras are quite simply some of the strongest around, producing crisp, punchy shots in all light conditions, impeccable ultrawide images, gorgeously lit 5x telephoto shots and adding the option to zoom up to 100x. The selfie camera, meanwhile, is a fantastic portrait lens, with perfect skin tones and strong focus.
Beyond the lenses, Google also has the deepest bench of editing features, a flawless display with incredible peak brightness and colour accuracy, seven years of software support and the new PixelSnap magnetic wireless charging feature.
The processor isn’t quite as fast as other flagships and battery life is on the weaker side but even still, these are the best phone cameras around right now.

Key specs – Processor: 3.78GHz Google Tensor G5; RAM: 16GB; Display: 6.3in, 2,856 x 1,280; Storage: 128GB, 256GB, 512GB, 1TB; Cameras: 50MP, 48MP (5x telephoto), 48MP (wide); Operating system: Android 16; Weight: 207g
6. OnePlus 13: Best-value flagship smartphone
Price when reviewed: £759 | Check price at Amazon
- Great for… blistering performance and high-quality display
- Not so great for… only four OS updates and not the best zoom photography
The OnePlus 13 offers a ridiculous amount of quality for its price. The Snapdragon 8 Elite processor delivers some of the fastest speeds on any phone, with gaming performance in particular displaying some of the most raw power of any phone we’ve tested. Battery life is on the better end of things, too, lasting for over 27 hours in our standard test.
Another element that decries the cheaper price is the display. This 6.82in QHD+ OLED screen is impeccably sharp, with a dynamic refresh rate up to 120Hz and fantastic colour accuracy – in our testing, we recorded an average Delta E colour variance score of just 1.09, which is right around our target of 1 or under.
Software support isn’t as extensive as the competition, only getting four major OS updates, and you’ll get better zoom photography from rivals but, if you want flagship-level power for a more palatable price, the OnePlus 13 is the ideal choice.

Key specs – Processor: 4.32GHz Qualcomm Snapdragon 8 Elite; RAM: 12GB, 16GB; Display: 6.82in, 3,168 x 1,440; Storage: 256GB, 512GB; Cameras: 50MP, 48MP (5x telephoto), 48MP (wide); Operating system: Android 15; Weight: 210g
7. Google Pixel 9a: Best mid-range smartphone
Price when reviewed: £449 | Check price at John Lewis
- Great for… incredible battery life and unrivalled software
- Not so great for… boring design and no telephoto camera
Quality phones don’t need to cost the moon and the Google Pixel 9a is the strongest argument there is for shopping in the mid-range. For starters, you get flagship-level software support, with seven years of updates, and Gemini AI features like Circle to Search and the Add Me camera editing tool.
Battery life is also exceptional, lasting for over 34 hours in our standard testing, which is one of the best results we’ve ever seen. The display is gorgeous, too – we measured brilliant peak brightness with HDR video playback and the average Delta E colour variance score of 0.67 speaks to excellent colour accuracy.
The two cameras you get are both fantastic, producing sharp, beautifully coloured shots, but some rivals offer telephoto cameras, so it’s a shame that Google doesn’t. The new design is also very generic but otherwise, this is a ridiculously well-rounded phone and the best option for those who don’t want to pay flagship prices.

Key specs – Processor: 3.1GHz Google Tensor G4; RAM: 8GB; Display: 6.3in, 2,424 x 1,080; Storage: 128GB, 256GB; Cameras: 48MP, 13MP (wide); Operating system: Android 15; Weight: 186g
8. Samsung Galaxy Z Fold 7: Best foldable smartphone
Price when reviewed: £1,549 | Check price at John Lewis
- Great for… impressively slim and seriously powerful
- Not so great for… no S Pen support and not fully dust-proof
Foldable phones are finally at a point where they’re barely any more cumbersome than regular handsets, and the Samsung Galaxy Z Fold 7 is the best of the bunch. It’s incredibly slim and lightweight, measuring just 4.2mm thick and weighing 215g, which is lighter than plenty of non-folding phones.
It’s also very powerful, with the Snapdragon 8 Elite for Galaxy chipset delivering the fastest speeds we’ve ever seen from a foldable phone, and the 200-megapixel main camera is a fantastic shooter, capturing crisp and colourful images in a range of lighting conditions.
Both the 8in internal display and 6.5in cover display are sharp, bright and punchy but the foldable screen no longer supports the S Pen stylus, which is a shame. We’d also have liked to see better dust resistance, with the current rating only certifying it as protected against particles over 1mm in diameter.
Even still, if you fancy the foldable format and want to nab yourself the best version possible, the Samsung Galaxy Z Fold 7 is the strongest and most powerful foldable we’ve ever tested.

Key specs – Processor: 3.1GHz Google Tensor G4; RAM: 8GB; Display: 8in, 2,184 x 1,968 (cover: 6.5in, 2,520 x 1,080); Storage: 256GB, 512GB, 1TB; Cameras: 200MP, 10MP (3x telephoto), 12MP (wide); Operating system: Android 16; Weight: 215g
How to choose the best smartphone for you
How much should I spend?
With the expansion of the mid-range market, you can easily get a very competent smartphone for less than £500. The best in this price range will have performance, stamina and cameras that will be more than enough for most people. We’d always recommend checking out the best mid-range phone listed above before forking out on a flagship.
If you want the absolute best phone that money can buy, however, you’re looking at anything from £800 to £1,250, depending on your priorities. The lower end of that range will get you most flagship features, with excellent performance and displays, but you’ll only find the most expansive camera systems at the high-end.
Finally, foldable phones are becoming more popular every year and, depending on how much storage you want, these can cost anywhere from around £1,500 to over £2,000.
What kind of features should I look out for?
If you’re spending four-figures on your next phone, you’ll want to make sure that you get all of the bells and whistles for your trouble. Here are the key considerations to bear in mind when shopping for a new phone.
Display
There are two main types of display that you’ll see from smartphones: LCD panels tend to be found on cheaper phones while OLED screens usually cost a little more. With the latter, you’re paying for extra quality, as they deliver a beautifully deep, inky black level and near perfect contrast, as well as better viewing angles compared to LCD displays.
You’ll also want to check the resolution and refresh rate, to see how sharp everything will look and how smooth things like scrolling and gaming will be. Further, our in-depth testing reveals how bright the display can get and how accurately it reproduces colours.
Cameras
Flagship phones have come such a long way on the photography front that you’re unlikely to be disappointed by any of their cameras. It’s worth checking what you get for your money, however – in particular, the optical zoom offered by telephoto cameras differs from brand to brand, and some include more robust video recording features such as capturing LOG, 8K or Dolby Vision footage.
Battery life
You can get an idea of a phone’s stamina potential from the battery capacity (measured in mAh, or milliamps-per-hour) but our review testing goes one step further, putting each phone through the same standardised test to directly compare them. You can check out the top results on our best phone battery life ranking.
Performance
The clock speed of a phone’s processor (measured in GHz) and the amount of RAM offered give a good general idea of how powerful a phone will be, but once again, our testing puts things in perspective. We directly compare the CPU and GPU performance of each phone we review against rivals around the same price, so if you want to see how it stacks up, you can view our results in the full review.
Storage
The best smartphones will offer a selection of storage capacities – usually some combination of 128GB, 256GB, 512GB and 1TB – but few of them support microSD cards that allow you to expand the storage any further. Higher storage models are naturally more expensive but if you intend to shoot lots of high-resolution videos or download a bunch of apps, it’s worth considering if you’ll benefit from the extra space.
