Which mobile phone brand to buy in 2026
A certified smartphones, tablets and wearables whizz, Adam's been hands-on with tech for more than six years, sharing expert knowledge and buying advice.
To find the most reliable smartphone brands for 2026, we asked 15,755 Which? members and the public to tell us whether they're happy with their smartphone and if they've experienced problems, so you can see which brands are worth investing in.
We analysed the performance and reliability of the biggest smartphone brands: Apple, Google, Honor, Motorola, Nokia, OnePlus, Samsung, Sony and Xiaomi. We checked real customer satisfaction and whether you actually get good value for money. Some big names deliver. Others fail.
Our crucial finding is which phones break the fastest. Trouble usually starts with significant battery life degradation. Or the device becomes sluggish, the screen freezes or the phone crashes unexpectedly.

Choosing a phone from a brand that’s reliable and has high customer satisfaction will help you avoid problems developing over time, such as a struggling processor or shortened battery life. It can also save you money by delaying your next upgrade.
Which mobile phone brands have the fewest faults?
We pour thousands of hours into our annual tech survey, and our exclusive data clearly separates the dependable daily drivers from the digital duds.
While a select few household names secure flawless five-star reliability ratings and incredibly low fault rates, our independent research reveals that others are leaving their customers stranded with rapid battery drain and dismal customer satisfaction scores. Which? is 100% independent and funded by our members – we don't take freebies from tech giants. This means we can reveal exactly which brands are built to last without fear or favour.
Look at the data in our interactive table below. Click the column headers to sort the manufacturers by reliability rating. Or sort by customer score. That metric reveals exactly how happy owners are in the real world – and if they would actually tell a friend to buy one. Dive into the numbers ahead of your next phone purchase.

How we discover the most reliable mobile phone brands
As a tech expert who has spent over six years reviewing everything from budget Androids to ultra-premium folding phones, I know how easy it is for a device to look flawless when it first comes out of the box. But true value isn't about how a phone performs on day one; it's about how it holds up on day 1,000. I believe you deserve tech that goes the distance, which is why we don't just rely on our rigorous lab conditions – we turn directly to you.
Every year, we ask thousands of Which? members and the public to tell us about the tech they own. For this 2026 dataset, 15,644 people provided detailed accounts of their experiences with more than 58,000 individual products. We look specifically at phones bought over the past 68 months, asking owners if they've experienced faults, how severe those faults were, and whether they'd genuinely recommend the brand to a friend.
Because we are 100% independent, we don't accept freebies from tech manufacturers, and we don't bend to marketing hype. This combination of exhaustive, independent lab testing and massive, statistically robust real-world data means we can confidently separate the brands that are truly built to last from the ones that are destined for the landfill.
Our surveys, combined with our extensive lab tests, enable us to recommend the best smartphones to buy. Find out more about how we test smartphones.
Head to our smartphone reviews
We independently test more than 65 smartphones a year at all prices, from £80 to nearly £2,000. Our extensive scientific tests mean each phone is tested under identical conditions, so they're directly comparable. Our scores take into account what’s important to consumers. We remove Best Buy recommendations from phones that will run out of security updates within one year, so you don't end up with one that will soon be out of date.
