What size phone should I get?

Phones with smaller screens are likely to sit more comfortably in your hand. Larger phones are more suitable for work and if you use your mobile to watch lots of videos, as you'll get a bigger screen.

Top tip: If you're worried about a phone being too big, some brands have compact versions that pack all the main features into a smaller design.

Phone Specifications Guide

When it comes to smartphones, it's what underneath that matters and it's vital to choose one with the right camera, connectivity and specifications to suit your needs.

Camera features

If your phone is your main way to take photos, a good camera is a must. Most phones have two cameras; a front one for selfies and a rear camera for everything else.

Megapixels – Generally, the more megapixels a camera has, the better picture quality you'll get.
Auto-focus – Gives clearer results by helping the camera concentrate on people or objects.
Image stabilisation – Prevents blurry images by compensating for camera movement.
4K video – Some smartphones can now record videos in 4K – the highest quality of video recording.

How much storage do I need?

Most phones come with built-in storage, but the amount you need depends on how much you plan to keep saved.

Low usage – 8GB to 16GB – Basic file, app and image saving.
Medium usage – 16GB to 32GB – Ample storage for music, some videos, apps and games.
High usage – 64GB – Space for TV shows, films and a large music collection.

Top tip – Most phones come with pre-installed software which can take up a portion of storage. This means a phone with 16GB might only have 12GB free.

What if I need more storage?

If your phone has a MicroSD slot, you can add more storage with a memory card.

Top tip: Some smartphones come with free online cloud storage, helping to free up space and letting you access your files whenever you need them.

What type of processor do I need?

Processors determine how well your phone can multi-task. The more cores a processor has, the more things it can do at once. You can find out what processor a phone has on individual product pages.

Does RAM matter when it comes to smartphones?

Yes! More RAM (random access memory) should mean better performance and smoother
multi-tasking. 2GB RAM will offer a noticeable improvement over phones with 1GB. Some models offer up to 4GB and 6GB if you're after strong gaming and multi-tasking performance.

Key features

Here are some of the key features to look out for when searching for your new mobile.

Fingerprint sensor and retinal scanning – Sensors add an extra layer of security to your mobile, meaning the only person who can get into your phone, is you.
Dual SIM – Manage two different SIM cards on your phone. Great for separating work and personal use.
Battery Life – Mobiles have varying battery life and if you're constantly on-the-go, you may need one that'll last longer. Specifications and performance can impact battery life, so we recommend you check individual product pages for more information about how long a phone will last between charges.
Waterproofing – Many phones are now waterproof, giving you protection against wet weather and accidental drops into water.
