Which? tests uncover Don’t Buy smartphone

The latest smartphone scores revealed

Man using mobile phone

We’ve put a batch of four new smartphones to the test and can reveal that one is best avoided. We scrutinised each mobile to see how it fared in everything from call and screen quality to speed and battery life. 

This batch included cheap models such as the Vodafone Smart 4 Turbo as well as the likes of the more expensive Samsung Galaxy S5 Mini. Our results reveal some bargains as well as one cheap model that doesn’t offer value for money.

Which models have we put to the test? 

Our latest batch includes the following four models:

  • Samsung Galaxy S5 Mini – a scaled-down and more affordable version of Samsung’s flagship phone, the S5 
  • Samsung Galaxy Young 2 – a phone with a very tempting price tag 
  • Nokia Lumia 530 – a cheap and brightly coloured Windows smartphone 
  • Vodafone Smart 4 Turbo – Vodafone’s bid to capture the Android phone market  

If you’re looking for something with a higher profile, we’ve also tested the new iPhone 6 and the huge iPhone 6 Plus. 

How do we test smartphones? 

Each and every smartphone that passes through our test lab faces the exact same set of tests, so you can compare like-for-like and work out which smartphone best suits your needs and budget. 

We test call quality to the max by making calls in a noisy environment, and assess battery life to find out how long the phone will last when making calls or browsing the internet. 

Now that phones are capable of handling so many daily tasks, from checking emails to playing games and streaming video, it’s important that they have a processor that’s up to the job. We test each mobile for speed to see whether it’s got enough pace or will keep you waiting around. 

As more and more people are using their phone as their main camera, we take a range of shots in different conditions to see whether they have decent snappers. 

We combine the data from all our tests to provide our verdict as to whether the phone is a Best Buy, Don’t Buy or somewhere in between.
