Buying a smartphone: a guide for everyday life, work and leisure

If you’re looking to buy a smartphone, you’ll often start by comparing the price, camera resolution or screen size. But these figures alone won’t tell you whether a device is really right for everyday life in the UK. Network support, storage technology, software update period, battery use and what’s included in the box are important too.

Common pitfalls when buying a smartphone

1. A high megapixel count doesn’t automatically mean better photos

A 50- or 108-megapixel camera can capture plenty of detail in daylight. But image stabilisation, sensor size, lens, software and lighting conditions all affect the actual picture quality. Even an affordable smartphone with a high resolution can struggle with night-time shots or moving subjects.

2. Virtual RAM isn’t a substitute for physical RAM

Some manufacturers add several gigabytes of virtual memory to the stated RAM. This uses the phone’s internal storage and doesn’t work in quite the same way as physical RAM. A moderate amount of RAM is enough for many everyday apps. But if you’re planning to use a gaming smartphone or multitask heavily, check the actual RAM figure.

3. Protection ratings and charging accessories are often misunderstood

A rating such as IP54 indicates protection against dust and splashes, not submersion. Even higher ratings don’t guarantee lasting protection against water damage. Some devices also don’t come with a mains charger. Before you buy, check the charging speed, compatible standard and what’s included in the box.

The key specifications to consider when buying a smartphone

Display: size, panel and refresh rate

An AMOLED display typically offers deep blacks and high contrast. A 90 or 120 Hz refresh rate makes scrolling feel smoother, although a higher refresh rate can affect battery life. If you read a lot or watch videos, also check the resolution, brightness and overall dimensions.

Mobile network, SIM and NFC

A 5G smartphone makes sense if your mobile plan and location support 5G. If you need two phone numbers, a dual-SIM smartphone could be a good option. Check whether the second slot can also be used for a microSD card. NFC enables features such as contactless payments, but you’ll also need a compatible app, authorisation from your bank and suitable infrastructure.

Battery, storage and updates

Battery capacity, measured in mAh, is useful for comparisons, but it doesn’t tell you exactly how long a charge will last. Screen brightness, searching for a network, gaming and camera use all affect power consumption. When choosing a smartphone with long battery life, consider charging speed and power management as well as capacity.

When it comes to storage, 128 GB may be enough for calls, streaming and the occasional photo. If you store lots of videos, games or offline maps, choose a smartphone with plenty of storage. A microSD card is a handy way to expand it, if the model supports one. The promised security and system updates also matter if you want to keep your phone for longer.

FAQs about buying a smartphone

How much storage should a smartphone have?

128 GB may be enough for calls, messaging and streaming. If you take lots of photos, shoot 4K videos, play games or save content for offline use, 256 GB or more is a sensible choice. A microSD card offers extra flexibility, but not every model supports one.

How long does a smartphone last in everyday use?

How long a phone remains useful depends on battery wear, care, repair options and software updates. A device with promised security updates, enough storage and a replaceable or well-supported battery could remain practical for longer. Protection ratings can’t prevent every kind of damage from drops or liquids.

What are the ongoing costs?

Alongside the purchase price, you may need to budget for mobile service, optional accessories, screen protection and repairs, depending on how you use your phone. A 5G smartphone requires a compatible plan. Remember to include the cost of a charger if one isn’t supplied.
