Reviewing tablets is a more complex process than one would expect. It requires a systematic approach to evaluating each device's features and capabilities. Analyzing each feature involves following a checklist to ensure a comprehensive and objective testing process.

At ZDNET, we evaluate each product, including tablets, from our first impressions during unboxing to its long-term performance and value for the money. This thorough process helps readers make well-informed purchases, ensuring they choose a tablet that best suits their needs.

How we test tablets in 2024

From unboxing to benchmark tests to everyday use, ZDNET reviewers test tablets for a set amount of time while evaluating materials, display, processor performance, battery life, software, and more features. Consumers primarily buy tablets for entertainment and productivity, so ZDNET takes great care to test a tablet's different features and recommends only those that offer great value. 

What makes a tablet ZDNET recommended?

ZDNET recommends tablets that our reviewers confirm have excelled in critical testing areas, including the display and build quality, overall performance, ease of use, battery life, extra features, and value for money. 

A tablet doesn't need to be a legendary piece of tech to earn a ZDNET recommendation -- we want to ensure it meets or exceeds its advertised capabilities and is worth a buyer's hard-earned money.

Unboxing process

June Wan/ZDNET

The unboxing process for a tablet entails evaluating the quality of the device, its packaging, and its included accessories. First impressions matter when opening a new device that costs a fraction of your take-home pay -- and manufacturers know this.

The unboxing process can set the tone for the review as it is the first user's experience with the product. As reviewers, we consider the manufacturer's effort in the unboxing experience, from product packaging meant for protection to how sustainable the packaging is.

This is also when we inventory what is included with each device. We note if it includes a charging cable and brick or just the cable and what else the consumer receives with their new tablet.

Assessing the display

Turning on a new tablet can be a satisfying experience, but it's also when the display can begin showing off. A tablet's touchscreen display is the user's primary interface; it must have great marks in usability, productivity, and enjoyment. 

After measuring the screen size and evaluating the resolution, I like to measure the brightness level in different lighting conditions and assess color accuracy. 

We also compare the display's performance with what the manufacturer promised, test the screen's responsiveness to touch, and assess the performance of any extra features, like a manufacturer's stylus.

Evaluating performance

Jason Hiner/ZDNET

There are different quantifiable ways to measure a device's performance. Some reviewers may run software-based benchmarks, including CPU, GPU, storage, and web browsing. These benchmarks can be done with third-party software like Geekbench, GFXBench, AndroBench, and Octane.

For real-world performance metrics, reviewers may also measure how quickly the tablet reacts to input, assess game performance and frame rates, test how the tablet handles having multiple apps running simultaneously, measure the time it takes to launch apps, and even assess the tablet's temperature during intensive tasks. 

Battery life: Testing the limits

Reviewers also consider battery life from a full charge to depletion when testing tablets. They may test different scenarios, including measuring how long the battery lasts while streaming, web browsing, using productivity apps, and playing games.

A reviewer may also measure performance and device temperature as the tablet's battery depletes.

Audiovisual: Camera and Audio

June Wan/ZDNET

Though audiovisual performance can be highly subjective, there are ways to measure a tablet's audio and camera quality objectively. ZDNET focuses on creating an informative and helpful mix of objective and subjective measurements.

For cameras, the evaluation features include resolution, aperture, low-light performance, autofocus accuracy, dynamic range, color accuracy, image quality, sharpness, and video quality. We also assess the camera app's user interface and settings array.

Tablets are often used as entertainment devices, so many users look for great audio performance. When testing a tablet's audio performance, ZDNET reviewers look at the sound quality and overall listening experience, including audio clarity at different volumes, stereo separation of left and right audio channels, maximum volume level in different environments, and if there is perceived distortion.

A tablet's value for money

Jack Wallen/ZDNET

Tablets are already expensive devices, but the market features various models for all budgets. Someone on a very tight budget will likely have to sacrifice some features from more high-end models, but they're still likely to find an adequate tablet at their preferred price. 

Determining a tablet's value for money is highly subjective. Still, ZDNET reviewers take great care only to recommend tablets that we believe offer value for money and avoid recommending overpriced devices that don't meet the advertised expectations.

When buying a tablet and determining how much you will spend, prioritize features you aren't willing to compromise on, like screen size or resolution, operating system, storage, processor performance, and more. Then, you can create a column for features that would be great but aren't essential and another for features you don't care about. 

After that, you can compare features, performance, and price side-by-side to make an informed decision and ensure you're paying for the most important features. 

Everyday and long-term use

Kerry Wan/ZDNET

As with most tech devices, evaluating how a device performs through everyday and long-term use can yield different results than controlled and quantitative testing. Most tablets will be used daily by consumers, so ZDNET reviewers also evaluate how functional the device is in completing daily tasks for entertainment and work. 

Some issues, like reduced performance or battery life, tend to appear after long-term use, so many of ZDNET's reviews are constantly updated with the writer's latest experience with the device. 

Frequently asked questions

How do you choose a tablet?

There is a tablet for anyone, from kids to productivity-focused workers, and for all budgets, from under $100 to over $2,000. Narrowing down which tablet to buy can seem daunting, so here's what you can consider while shopping:

Purpose: Tablets serve different purposes for different users, so the purpose of your soon-to-be tablet is worth considering when choosing the right one. Kids may use one to play and stream, while adults may use one for reading or graphic design. If you're looking for an entertainment tablet, it's worth considering one with a high-resolution display and good speakers. If you need one for productivity or work, you're better off with a strong processor and the ability to use it with a keyboard or stylus.Performance: A tablet is only as good as its performance, so if a fast processor and good responsiveness are essential to you, look for tablets with a powerful processor. Storage is equally important; larger RAM translates into better multitasking capabilities. Also, internal storage and options for expandable storage should be considered.Operating system and compatibility: iPhone users may prefer an iPad with seamless integration with more Apple products, like AirPods being able to switch between the iPhone and iPad without intervention. The same can be true for Samsung fans. Android tablets feature various brands and models, have more customization power, and are available in wider price ranges. Windows tablets are good for productivity, especially if you need compatibility across desktop apps.Price: The price range will narrow down the list of tablets considerably. These devices are already expensive, but budget and premium options are available. It's worth considering if high-end features justify the cost for your needs.Battery life: Look for long battery life, especially if you plan to use your tablet on the go. You'll need it to last for the duration of your task.Extra features: Some extra features may be exclusive to only some tablets, so consider whether these are important. These features include camera quality, headphone jack, USB-C charging port, weight, compatibility with accessories, and size.

How can you check if a tablet is good?

Though every user has a different idea of a "good tablet," some factors to consider include fast performance, ability to multitask, sufficient storage for apps, media, and files, long battery life, large-resolution display, and audio performance. 

Are tablets often on sale?

Tablets are commonly featured in sales events, promotions, and bundle deals. If you want to save on a tablet, you can wait for the next big sales event, like Prime Day or a holiday, to see if it's discounted.
