Here’s our honest analysis of the NUU B20 5G. We’ll help you decide whether to get this smartphone or look for something newer and more advanced.

Design and Build Quality

NUU B20 Design and Build Quality

Despite being two years old, the NUU B20 features a solid design. From the front, the phone looks modern with its punch-hole design.

While the bezels are not the thinnest, they are still decent, although the bottom bezel is noticeably larger. This is somewhat acceptable, especially since even modern phones like the Google Pixel 8A still have larger bezels.

The smartphone’s back has curved edges, providing a better and more comfortable fit. The back and side frames are made of plastic, which is expected for the price.

Both color options, Daydream Purple and Stardust Blue, remain visually appealing. Despite its larger size, the NUU B20 is comfortable to use and hold. It doesn’t offer a premium feel, but it doesn’t feel cheap either.

Overall, the NUU B20 5G is a decently built phone with an adequately modern design, even today.

Display

NUU B20 Display

The display is the main highlight of the NUU B20 5G, boasting an FHD+ resolution with a 90Hz refresh rate.

This display is colorful, with vivid and lifelike colors. You can also tweak the color settings to your preference.

Because of the FHD resolution, you won’t notice any pixelation, and all text and images look sharp.

The brightness is decent, although you might have difficulty reading the display in direct sunlight.

The 90Hz refresh rate makes everything feel smooth. While it isn’t as smooth as a 120Hz display, it is better than the standard 60Hz.

Overall, the display quality is satisfying, and you won’t face many problems with it, especially considering the price.

Performance

NUU B20 runs on the MediaTek Dimensity 700 MT6833, which is a reliable budget processor.

In terms of performance benchmarks, it boasts an Antutu score exceeding 350,000, which significantly surpasses the Snapdragon 695’s score of around 250,000.

Having used several phones equipped with the Snapdragon 695, we’ve observed that it’s capable of handling everyday tasks smoothly. With the MediaTek Dimensity 700 MT6833 onboard, you can expect even smoother performance.

The stock UI contributes to seamless navigation devoid of lags.

For general usage, the NUU B20 won’t disappoint. Yes, the demanding games won’t run smoothly, but the lighter to medium-heavy games run smoothly at lower settings.

Overall, the NUU B20 remains a solid choice for basic smartphone usage, offering satisfying performance that holds up well even by today’s standards.

Camera

NUU B20 Camera

Camera processing requires considerable time and effort, which is why many budget phones struggle to deliver a robust camera setup.

The NUU B20 follows a similar narrative but with some enhancements.

For example, the 48MP camera captures decent pictures in bright daylight but falters in low-light conditions.

While most smartphones in this price range lack an ultra-wide camera, the NUU B20 includes a 16MP ultra-wide camera. The photo quality is satisfactory in daylight but average in low-light situations.

The 2MP macro camera seems more symbolic than functional, producing photos primarily to demonstrate its capability rather than for practical use.

The 8MP front camera also delivers decent overall performance.

Considering the price point, exceptional picture quality isn’t expected, but the NUU B20 provides serviceable camera performance. However, users shouldn’t anticipate outstanding results.

Overall, the camera quality is average in low-light conditions and somewhat acceptable in well-lit environments.

Software and User Experience

The software is both the best and worst feature of this smartphone.

The good part is its clean and simple interface, which makes it feel like a premium device.

We loved this aspect when the phone first came out.

The CPU is pretty good, and with the clean interface and high refresh rate, everything runs smoothly. Sometimes, there are slight stutters, but overall, it’s a great experience because of the stock UI.

But here’s the disappointing part. The phone doesn’t get any software updates. Sure, there have been a few fixes for bugs and security, but no major updates.

Because of this, we can’t recommend it to anyone who wants a safe and up-to-date experience.

While the interface looks nice, the lack of updates is a big letdown.

Battery Life

The NUU B20 boasts a 5000mAh battery, which is still impressive today. Since it’s a budget phone with a not-so-power-hungry CPU, you’ll get excellent battery performance.

With normal to moderate usage, you can easily achieve 7 hours of screen-on time, which is pretty good.

The phone comes with an 18W charger in the box. While it’s not super-fast anymore, it’s still convenient that you don’t have to buy it separately.

Charging the battery fully takes about 2 hours, which might seem slow nowadays, but it’s acceptable considering the great battery life.

Overall, the battery life on the NUU B20 is excellent. With light to moderate usage, you can expect it to last a day to a day and a half on a single charge.

Additional Features

  • The NUU B20 supports 3.5mm headphones, which is great for users who prefer wired audio.
  • The single bottom speaker delivers decently loud audio, although it lacks stereo effects.
  • There are no connectivity problems during calls.
  • The phone works with most carrier networks, but it’s not compatible with Verizon, Boost Mobile, Tracfone, Pulse Cellular, Union Wireless, and Spectrum.
  • It also includes a 12-month manufacturer warranty.

Price and Value for Money

When the phone first launched, we were impressed by its pricing, as it offered great specifications for the price.

Now, after two years, the price has dropped from $219 to $140. On the official website, it’s listed at $170, but NUU is currently running a Dads & Grads offer: Buy 1 Get 1 Free.

This means you can get one phone for just $85. While most people won’t need two identical phones, you could give the extra one to a family member.

Considering this offer, the NUU B20 becomes an excellent value for money. Even without software updates, it’s still a good buy at $85.

At $140 to $170, it’s not an easy recommendation, but it’s still somewhat worth buying.

We’re not saying it’s an amazing value at $170, but you can consider it if you need a secondary phone.

User Rating and Satisfaction

We carefully analyzed user feedback and found that most people were satisfied with the phone when it was launched.

However, without any updates, the software has become sluggish, and smoothness has suffered. Some users even reported the phone becoming unusable after the last security patch update.

Additionally, it’s frequently returned on Amazon, indicating overall dissatisfaction among buyers.

Taking everything into account, user satisfaction has dropped from good to below average.

Most users are no longer happy with the NUU B20 5G smartphone. While it used to be a great budget option, it’s no longer recommended.

Conclusion: Is NUU B20 Worth it in 2024?

Honestly, we wouldn’t recommend the NUU B20 phone in 2024.

The main reason is that it’s no longer supported for OS updates, and recent security updates have made some units unusable. Additionally, this phone is not compatible with Verizon, Boost Mobile, Tracfone, Pulse Cellular, Union Wireless, and Spectrum.

You might consider it in a buy-one-get-one offer, but at $140 to $170, it doesn’t make much sense.

While there may be limited options at this price, it’s better to go for newer models for a more secure and up-to-date experience.
