Mobile phone reviews you can trust

We've reviewed hundreds of handsets over the years from all the top brands, including Microsoft, Sony, Samsung, Blackberry and Apple. We always test a mobile phone’s essential features - sound quality on calls, ease of use and battery life. And because mobiles are crammed with more and more features these days our experts assess these too. So we test the cameras in different lighting conditions, record and view footage shot on the phone’s camcorders, rate the built-in music players and even look at the performance of each phone’s web browser.

Which? is independent - we work for you, the consumer, so you can be sure that our product recommendations are influenced only by our test results. We don't take advertising and we buy all the products that we test ourselves, so our advice helps you to make the right choice first time and avoid costly mistakes.
