How to buy a tablet: choose a model that suits your daily use

Buying a tablet might seem straightforward, until you have to choose between screen sizes, Android versions, storage capacity and mobile connectivity. A low price doesn't tell you much about whether it's right for your situation. A compact model might be great for travelling, but less convenient for split-screen work. A large screen looks appealing, but takes up more space in your bag and your hands.

When comparing, pay close attention to the specifications behind the marketing jargon. Below, you'll find out which pitfalls often lead to a bad purchase, which features really make a difference, and which models suit different types of users in the UK.

Three common pitfalls when buying a tablet

1. Confusing virtual memory with real RAM

You sometimes see specifications like 16 GB, 20 GB or 48 GB RAM. Part of that can be virtual memory that uses storage space. It helps keep apps open, but it's not the same as physical RAM.

Always look at the breakdown, for example 8 GB + 12 GB virtual. For browsing, streaming and studying, 4 to 8 GB of physical RAM is often a practical starting point. For intensive multitasking or creative work, the processor, physical RAM and storage type together matter more than one high total number.

2. Overestimating a high refresh rate

A 90Hz or 120Hz screen can make scrolling and animations feel smoother. That makes a tablet with 90Hz appealing for social media, gaming and navigating. However, it doesn't automatically tell you anything about brightness, resolution, colour reproduction or processor speed.

So also check the screen resolution and panel type. An 11-inch tablet with 1280 × 800 pixels has a different sharpness to an 11-inch model with 2560 × 1600 pixels. For text, online lessons and spreadsheets, you'll notice that difference more quickly than with simple videos.

3. Not checking storage and mobile connectivity

128 GB of storage can be enough for daily use, but apps, offline videos and photos quickly take up space. Check whether a microSD card is supported and what the maximum capacity is. A tablet with plenty of storage is especially handy when several family members use the same device.

A tablet with 4G LTE also doesn't work automatically without configuration. You'll need a suitable nano-SIM card and a mobile data plan. Also check whether the model actually supports LTE; Wi-Fi only is not the same as mobile internet.

Which specifications are important?

Screen size and resolution

  • 8 to 9 inches: light and compact for travelling, reading and navigating.
  • 11 inches: a practical middle ground for streaming, studying and light productivity.
  • 12.7 inches or larger: more workspace for drawing, documents and split-screen use.
  • Resolution: higher values generally give more detail, especially with text and illustrations.
  • Refresh rate: 90Hz or higher can make motion appear smoother, but affects battery life.

A 12.7-inch tablet is comfortable on a desk, but less easy to hold in one hand. If you mainly use it on the train or on the sofa, it's better to factor in the weight and dimensions.

Processor and physical RAM

For streaming and web apps, a recent Android version, sufficient physical RAM and a suitable processor are important. An octa-core chip can be suitable for daily multitasking, but performance also depends on clock speed, graphics chip and software optimisation.

For studying and working from home, features like split screen, Bluetooth keyboard support and USB-C are practical. For gaming or video editing, a more powerful processor and faster storage are more relevant than just a large RAM number.

Battery, charging and accessories

Battery capacity is expressed in mAh, but actual usage time also depends on screen brightness, Wi-Fi, mobile data and apps. Manufacturer claims about video or music playback time are based on their own test conditions. According to DOOGEE's own figures, the U11 can play video for up to 11 hours; treat this as an indication, not a fixed usage time.

Also check whether a charger is included. According to the product information, the Lenovo Idea Tab no longer comes with a charger as standard. The Lenovo Idea Tab Pro mentions charging up to 45W via USB Power Delivery, but you'll need a suitable adapter for that.

Frequently asked questions about buying a tablet

Is an 11-inch tablet suitable for studying?

For most online lessons, PDFs, video calls and notes, an 11-inch tablet is a practical choice. Check whether the model supports split-screen and whether a keyboard or stylus is compatible. For extensive spreadsheets or lots of windows, a 12.7-inch or 14-inch tablet offers more workspace.

How much storage do I need?

For basic use, 64 GB can be enough, as long as you mainly work online. Choose 128 GB or more if you store lots of apps, photos, downloads and offline streaming content. A microSD slot offers extra flexibility, but not every app or download can be placed on it.

Is a tablet with 4G LTE more expensive to use?

In addition to the purchase price, you'll need a nano-SIM card and a mobile data plan. Usage depends on video quality, video calls and hotspot use. Check which LTE bands are supported before buying, and whether your provider offers a suitable plan.
