The last two years have seen 5G phones become increasingly easier to find and at a more affordable price. You’re now spoiled for choice when it comes to picking the best 5G phone.


A phone with 5G connectivity should give you faster download speeds so that you can watch your favourite Netflix or Disney Plus show quicker and more easily. But, a 5G-ready phone still needs to get the basics such as battery life, camera and display right, too.

Here are the best 5G phones to buy in 2021, along with some advice on where to spend your money and additional features to consider.

How to choose the best 5G phone

So, you’ve decided you want a 5G phone. Now, you need to establish a budget and choose which features are essential for you to have.

  • Price: When the first 5G phones were being released, they tended to be on the pricier end. Now, a 5G phone can cost anywhere between £200 and £1,800. You definitely do not need to spend over £1,000 to get a good 5G phone either. If you know you don’t want to spend a lot, make sure to check out our best budget smartphone guide.
  • Display: The size of smartphone displays now varies considerably from 6.2 inches all the way through to the 7.6 inches of the tablet-esque Samsung Galaxy Z Fold 2. If you watch a lot of videos and streaming services on your phone, you might want to invest in a bigger screen. However, this always has to be balanced with how big you want your phone to be and how easy it’ll be to carry around in your day-to-day life.
  • Battery life: Whether you’re buying a 4G or 5G phone, you want to be certain it will make it to the end of the day without dying on you. Decent battery life will easily last a full day with some extra charge left over. Keep an eye out for battery saver modes, too, if you know you’re guilty of forgetting your charger.
  • Storage: Most 5G phones offer one of two storage sizes; 128GB or 256GB. While 128GB should be enough for the average user, you might want to invest in the bigger 256GB model if you’re an avid downloader. With 256GB, you should have plenty of space for photos, videos and apps without having to rely on Cloud services. A 256GB model may also be a good option if you like to regularly download Netflix episodes to watch offline and don’t want to be constantly deleting to make space.
  • Camera: The camera setup is another area where smartphones can really vary. Most front cameras will be a punch-hole style in the corner of the screen. However, some can have a more sizeable bezel that can affect how big and undisrupted a display feels. The rear set-ups can typically contain two, three or four cameras. More cameras don’t always mean better quality photography. Consider what type of photos you most often shoot and shape your research around that.


Despite the new iPhone 13 only just being revealed, pre-orders are already live. 

Sky Mobile has some brilliant deals on the new models, so we’ve picked out some we think are worth shouting about.

How we tested the best 5G phones

All the smartphones in this guide have been tried, tested and reviewed by our tech experts. Each smartphone was tested against the same criteria before being given a final rating out of five.

The categories we considered included the phone’s design, camera, battery life, and features such as wireless charging and dual SIM support. These are, of course, weighed up against the phone’s price to decide if it is good value for money. This is essential when the cost of 5G phones can vary from £200 to a huge £1600.

To determine the scores (out of 5), we carried out a series of tests. For example, we timed the whole set-up process, from opening the box, through various updates, to being signed into all our favourite apps.

All the smartphones to make it into our best 5G phones guide received an overall rating of 3.5 or higher.
