The best mobile phones will take the place of your camera, mean your iPod doesn’t leave your desk drawer and allow a full working day of web browsing and calls without the need for a recharge.

The latest apps will run smoothly, and the screen will mean video and pictures look great and text is clear. See below for the key things to look for when choosing a new mobile phone. 

Take a look at our mobile phone Best Buys to discover the models we recommend.


How much do you need to spend for a good mobile phone? 

You can spend anything from around £15 to more than £800 on a smartphone.

If you want a premium top-of-the-range phone from the likes of Apple or Samsung, expect a dent of at least £550 in your bank account. Models in this range typically come with a large, extremely detailed and vibrant screen. Plus, they’ll have all the latest features – which can include anything from a fingerprint reader and heart-rate monitor to fast charging and waterproofing.

For around £400 mark, you’ll find phones with a good screen, long battery life and a decent camera. That said, they may not have all the bells and whistles – and they’re more likely to have a plastic finish rather than the sleek metal casing found on pricier models.

Spend at least £100 to avoid a complete dud

Looking for a phone that can simply manage everyday tasks? You might be able to get away with spending around £150 - £200. Phones in this price range shouldn’t struggle with web browsing, running Google searches and taking phone calls – but might not be up to the task of running the latest and most demanding games and apps.

If you just want the cheapest option possible, we recommend you spend at least £100 to avoid ending up with a complete dud.

All this said, there’s no hard-and-fast link between price and quality. We’ve found a few Best Buys that cost around £300 and less – and some expensive handsets unfortunately offer disappointing quality.

iOS, Android or Windows: which OS is best?

The operating system (OS) is the software that powers your phone. It shapes what the phone menu looks like and what apps it can run, and plays a large part in how easy it is to use. There are three main contenders to choose from: iOS, Android and Windows.

Apple iOS

All iPhones use iOS and, unlike Android, the experience of using the operating system is broadly similar whichever iPhone you buy. New updates to iOS are released each year, but some older iPhones may be able to run only older versions – for instance, only iPhones from and including the iPhone 5s can run the latest iOS 11.

If your iPhone isn’t compatible, you’ll miss out on some of the latest apps, features and security patches introduced by Apple.

  • Pros It’s easy to use and quick to learn, even if you haven’t used a smartphone before. It provides access to the well-stocked Apple app store – where apps are vetted before being released, so you can rest assured they’re safe to use.
  • Cons Apple iPhones are expensive – the latest iPhone 8 (64GB) will set you back by around £700, while the iPhone 8 Plus (64GB) costs around £800. And the all-new iPhone X (64GB) costs an eye-watering £999. If you're not obsessed with having the latest tech, you can find cheaper deals on older handsets, though. Apple iPhones also do not come with a micro-SD card slot, so you’ll need to choose the memory capacity carefully to avoid running out of space for your app, music and photo collection.


Android is designed by Google and is used by many manufacturers, from bigger brands such as SamsungLG and HTC to more emerging companies like Huawei, OnePlus and Wileyfox. Android looks and behaves slightly differently depending on who manufactures the smartphone handset, but the basics are essentially the same.

  • Pros It’s generally easy to use, extremely customisable and provides access to the wide variety of apps, games and entertainment available from the Google Play store. There's also loads of Android phones to choose from whatever your budget.
  • Cons In the past, Android has been slightly more vulnerable to attack than Apple handsets. That's beginning to change now, though - Google is putting more emphasis on vetting apps in the app store and patching security holes before they're released on the Google Play store. Sometimes the manufacturer and network provider can be slow to release Android updates to users – for instance, some phones still haven’t received the 2015 Marshmallow version, let alone 2016's Nougat or 2017's Oreo.


Windows is not as popular as Android or iOS, but it has a few options at the cheaper end of the market.

  • Pros Microsoft offers a range of decent-yet-affordable Windows phones – you can pick one up for around £120. Windows phones are fully compatible with Windows laptops and computers – good for finishing tasks while on the move.
  • Cons There aren’t as many apps made for Windows phones as there are for iOS and Android. That said, many of the major apps such as Facebook, Google Maps and BBC News are available.

Do I need a 4G phone?

Smartphones use mobile broadband networks to keep you connected. The fastest mobile internet service is called 4G and is available in parts of the UK. To check whether you can get 4G in your area, use our coverage checker map

Most mobile phones come with 4G as standard now, but some cheap smartphones don't. It's worth checking when you're choosing which mobile phone to buy, especially if you want to use your phone a lot for heavy internet use.

What size of phone is right for me?  

Smartphones are getting bigger and bigger, with the latest high-end models measuring 5.5 inches and more - including the Samsung Galaxy Note 8 and iPhone 8 Plus. While bigger phones are great for watching films and browsing the web, they won’t suit everyone. Some people find them too large and awkward to hold, and would prefer a model they can comfortably use with one hand.

The best way to find out which handset size is right for you is to try holding a few in a shop. If you do want something that will slip more easily into your pocket or bag, pick a 4-5-inch phone.

What about waterproof phones?

You might be tempted by a water-resistant smartphone if you have nightmares about the time you dropped your phone into the sink, immediately immersed it into a bag of rice, and spent the next 48 hours desperately hoping all would be fine. More and more phones are claiming to be waterproof, but these are typically the pricier models on the market.

Bear in mind that some phones claim a higher waterproof level than others. For instance, Apple says the iPhone 8 and 8 Plus can survive submersion into 1 metre of water for up to 30 minutes, while Samsung says that the Galaxy S8, S7 and S7 Edge still work after being plunged in 1.5 metres of water for the same amount of time.

Interestingly, we're seeing some more mid-range phones with waterproofing. The Samsung Galaxy A3 (2017) and A5 (2017) both have IP68 ratings, making them as water resistant as the more expensive S-series line-up. This rating also makes them more waterproof than the iPhone 8 and 8 Plus - and some pricier phones, like the OnePlus 5T, aren't water-resistant at all.

Which mobile phone brand should I go for?

While Apple and Samsung are popular brands, they're certainly not the only options to choose from. We've tested models from the biggest brands to those that are starting to really carve their presence in the market, such as Huawei.
