Looking to buy the best mobile phone? Apple or Android? Cheap or premium? Find out how to choose right phone and which brands are most reliable.
22A great mobile phone will take the place of your camera, keep you informed and entertained on the move and still leave you with enough battery when you get home. But it’s not easy to find a model that can succeed on all counts. With prices rising and more than ever to choose from, it’s important to spend your money wisely on a phone that will last. Read our in-depth guide for advice on choosing the right operating system, brand and additional features that you’ll really use.
How much do I need to spend for a good mobile phone?
You could spend over £1,000 on a smartphone, but fortunately over recent years we’ve seen excellent models for a fraction of the price.
Expect to spend a little over £200 for a Best Buy. It may not have all the bells and whistles of premium competitors, but any phone good enough to be a Best Buy is guaranteed to tick a lot of boxes. What you’re typically missing out on versus the flagship models are high end cameras and high resolution video, a less sharp or colourful display, and less premium materials in the phone’s construction.
What you can get, regardless of price, are perfectly capable and versatile cameras that take great photos, impressive battery life, and processors that are more than fast enough for most day to day tasks.

We test smartphone cameras in ten different environments to test photo quality in low light, flash uniformity and colour accuracy.
The importance of security in a phone purchase
One important consideration for any phone purchase is how long it’ll received important security updates from the manufacturer. This is where brand can make a difference. Apple traditionally supports smartphones for the longest, at around 5 or 6 years. Android brands vary considerable, from 2 to over 4 years. This isn’t always easy to work out, and you need to remember that support durations start from when the phone is released, not when you buy it. To help inform a purchase, enter a phone into the tool below to see our estimate of the minimum remaining support.
iOS or Android: which OS is best?
The operating system (OS) is the software that powers your phone. It shapes what the phone interface looks like and what apps it can run, and plays a large part in how easy it is to use. There are two main players to choose from: iOS (Apple iPhones) and Android.
Android is designed by Google and is used by a range of manufacturers, from bigger brands such as Samsung and Motorola to growing brands like OnePlus and Oppo. Android looks and behaves slightly differently depending on who manufactures the smartphone handset, but the basics are essentially the same.
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 are also plenty of Android phones to choose from whatever your budget.
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. Sometimes manufacturers and network providers can be slow to release Android updates to users.
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, which means you’ll miss out on some of the latest features and security patches.
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.
Apple iPhones are expensive. 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.
What size of phone should I buy?
Smartphones are getting bigger, with the latest high-end models measuring between 5.5 and 6.5 inches or more. 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. Also pay attention to the physical dimensions of the phone. Screen sizes are available at different aspect ratios, and different phones have different sized bezels. A phone with a 6-inch screen may ultimately be smaller than one with a 5.5-inch screen.
Which mobile phones have the best battery life?
You might be tempted to think that phones with larger batteries have a better battery life. While battery size is a good indicator, that’s not always the case. There are multiple things that can drain a phone’s battery, including screen size, resolution and refresh rate, and the type of processor. We put all phones through a rigorous battery test to find out how long they last under real usage conditions – watching videos, browsing the internet, making calls, using the camera and more, and we factor in idle time as well, to give a realistic usage time, and attribute a star rating. If battery is the most important thing to you, you can browse all our mobile phone reviews to find a model that lasts.
Should I buy a phone on contract or Sim-free?
This is a key buying decision. It can be tempting to opt for a lower monthly fee rather than pay a lot outright for a new phone, but this could cost more in the long term. Use our phone contract calculator to find the best way to buy.
Should I buy a second hand mobile phone?
One way to get a good discount on a phone is to buy second-hand, or a refurbished model – which is usually a phone that has been used but restored to ‘as new’ condition, or graded to a certain level of quality. The second hand phone market is a popular one, but you do need to be careful what you buy. Read more in our guide to buying a second-hand or refurbished mobile phone.
Which mobile phone brand is most reliable?
The biggest fault people have with mobile phones is related to battery, with almost one in five reporting issues with phones refusing to charge, or quickly losing charge. We collect reliability data on all the big brand smartphones so you have all the very best advice before you buy.
