1. Samsung Galaxy A51

Samsung has historically had a spotty record in the budget phone sector, but its recent overhaul of the A series has led to some of the South Korean giant’s best affordable phones ever made. Case in point: the Samsung Galaxy A51.

The A51 is one of Samsung's best ever mid-range phones.

The Galaxy A51 combines style and features in the way you’d expect from any Samsung phone, with a top-quality 6.5-inch AMOLED display, a quad-camera setup (main, zoom, ultra-wide, macro), and a large 4,000mAh battery. It may not have the most powerful chipset on the market, but the Exynos 9611 is more than capable of handling everyday use and even 3D gaming.

The Galaxy A51 is priced at £329 as standard but regularly falls below that at a variety of retailers both online and on the high street.


Samsung Galaxy A51 specs:

  • Display: 6.54-inch, Full HD+
  • SoC: Exynos 9611
  • RAM: 4GB
  • Storage: 128GB
  • Cameras: 48, 12, 5, and 5MP
  • Front camera: 32MP
  • Battery: 4,000mAh
  • Software: Android 10

2. Redmi Note 9 Pro

Replacing its predecessor on this list, the Redmi Note 9 Pro packs lots of features and specs into its sub-£300 package.

Redmi’s priorities with the Note 9 Pro were design, performance, and battery life. Unsurprisingly then, this device does all three of these things really well. It’s got an eye-catching design that comes in three distinct colors.

Its main 64MP camera takes some solid photos and the huge 5,020mAh battery will last you all day on a charge. The 6.67-inch Full HD+ IPS display is unfortunately only 60Hz, but is surrounded by thin bezels and has a center-positioned punch hole for the 16MP selfie camera. 

Top it all off with a 3.5mm headphone port, a side-mounted fingerprint scanner, 30W fast charging, and microSD expansion and you’re getting a lot of smartphone for your money.


Redmi Note 9 Pro specs:

  • Display: 6.67-inch, Full HD+
  • SoC: Snapdragon 720G
  • RAM: 6GB
  • Storage: 128GB
  • Cameras: 64, 8, 5, and 2MP
  • Front camera: 16MP
  • Battery: 5,020mAh
  • Software: Android 10

3. Realme X50 5G

Realme has been busy in the past 12 months, releasing many smartphones across lots of different price points. One that stands out as being great value for money is the Realme X50 5G. 

It’s the only device on this list to come with a 120Hz display, and this one is in the 6.57-inch Full HD+ IPS flavor that comes surrounded by fairly thin bezels. Accompanying this silky-smooth display is a large 4,200mAh battery, 30W fast charging, and the very capable Snapdragon 765G SoC. 

Finding a 5G-enabled smartphone at this price point is tricky business, but the X50 5G manages to squeeze it in for under £300.

That last part is important because not only does it enable a respectable user experience, but also 5G connectivity. Finding 5G support in a phone under £300 is tricky business, and that’s what makes the Realme X50 5G such a great option.

Realme UI isn’t going to be for everyone, and the device isn’t perfect by any means. However, if you want a solid 5G-capable smartphone on a tight budget, the Realme X50 5G should be on your list.


Realme X50 5G specs:

  • Display: 6.57-inch, Full HD+
  • SoC: Snapdragon 765G
  • RAM: 6GB
  • Storage: 128GB
  • Cameras: 48, 8, 2, and 2MP
  • Front camera: 16MP
  • Battery: 4,200mAh
  • Software: Android 10

4. Oppo Reno 4 Z 5G

Oppo’s Reno 4 Z 5G swaps the OLED display from previous models for a super-smooth 120Hz IPS panel that prioritizes speed over image quality.

The re-imagined design features a punch-hole design as opposed to the predecessor’s implementation of a motorized camera module. This helps the Reno4 Z 5G feel more up-to-date in 2021 where the trend is to have a punch-hole display. The camera module has also been relocated to the top corner of the phone.

Speaking of the cameras, there are plenty of them with the Reno4 Z 5G. Included is a 48MP main camera, an 8MP ultra-wide, and two 2MP supplementary cameras to round out the camera package. There are two selfie cameras — a 16MP main camera and a 2MP depth sensor to help with portrait mode selfies. This device can shoot UHD 4K video at 30fps on the main rear camera and 1080p footage at 30fps on the front camera.

The Oppo Reno4 Z 5G brings a high-refresh-rate display to the masses.

Oppo opted to go with a MediaTek chipset for this device — the Dimensity 800 5G. This chipset is slightly more powerful than the competing Snapdragon 720G, but crucially supports 5G connectivity where the competing Qualcomm part doesn’t. The 4,000mAh battery and 18W fast charging fall in line with other offerings and should deliver both good battery life and relatively brisk charging.

Overall, the Oppo Reno4 Z 5G is a solid smartphone for those who want a very smooth 120Hz display as well as plenty of storage and 5G connectivity. 


Oppo Reno 4 Z 5G specs:

  • Display: 6.57-inch, Full HD+
  • SoC: MediaTek Dimensity 800 5G
  • RAM: 8GB
  • Storage: 128GB
  • Cameras: 48, 8, 2, and 2MP
  • Front camera: 16MP
  • Battery: 4,000mAh
  • Software: Android 10

5. Moto G 5G Plus

Motorola has a history of creating quality mid-range smartphones, with its G series being particularly prevalent. The Moto G 5G Plus is no exception to this and is focused squarely on performance.

With a Snapdragon 765G and Android 10, the Moto G 5G Plus is one of the more powerful devices on this list. That said, some will want to skip the 4GB RAM/64GB storage model at £299 and opt for the pricier but more versatile 6GB RAM/128GB storage model, which sits at £349. Both SKUs offer microSD expansion for those with large media libraries.

The device sports a sizable 6.7-inch Full HD+ LTPS display with a 90Hz refresh rate. This means that the phone is handy for watching video content and will feel smoother than a traditional 60Hz display when zipping around the operating system. Oddly, Motorola decided to split its dual selfie cameras into two independent punch holes instead of creating a pill-shaped punch hole. 

The Moto G 5G Plus is a powerful mid-range handset with a huge battery.

Motorola has packed in a massive 5,000mAh battery that should last you all day given the power-efficient mid-range chipset. When you need a top-up, there’s an included 20W TurboPower fast charger. All these things combined make the Moto G 5G Plus one of the best phones under £300 you can get.

To top it all off, there are six total cameras on the Moto G 5G Plus — two on the front, four on the back. Starting with the former, you get an 8MP standard shooter and a 16MP ultra-wide camera for added versatility. On the back, the quad-camera setup is centered around the 48MP main camera with an f/1.7 aperture. The additional cameras comprise of an 8MP ultra-wide camera, a 5MP macro camera, and a 2MP depth camera. Those last two are really only there to fluff out the spec sheet.

Overall, the Moto G 5G Plus looks to be a great option for those looking for a powerful mid-range smartphone with a good screen and a huge battery.


Moto G 5G Plus specs:

  • Display: 6.7-inch, Full HD+
  • SoC: Snapdragon 765G
  • RAM: 4GB
  • Storage: 64GB
  • Cameras: 48, 8, 5, and 2MP
  • Front camera: 16 and 8MP
  • Battery: 5,000mAh
  • Software: Android 10

6. Samsung Galaxy A42 5G

The second Samsung entry on this list trades a 1080p display and a punch-hole display for a larger battery and 5G connectivity.

The feature-packed mid-ranger sports a microSDXC card slot, a 3.5mm headphone port, and five total cameras. The 6.6-inch AMOLED display isn’t the sharpest on the market, but benefits from perfect blacks thanks to the OLED panel. The teardrop cut-out houses a 20MP selfie camera. The display is an area in which Samsung has cut corners to allow for more budget for the internal hardware.

Samsung packed the Galaxy A42 5G with a large 5,000mAh battery with 15W fast charging which, combined with the Snapdragon 750 5G chipset, should allow for all-day battery life and more raw power than even more expensive devices like the Google Pixel 4a. The Snapdragon 750G features both sub-6GHz and mmWave 5G connectivity for fast mobile data in 5G-enabled areas.

The Galaxy A42 5G trades a high-resolution screen for 5G connectivity.

The Galaxy A42 isn’t short on cameras. On the back, there’s a quad-camera setup which included a 48MP main camera and an 8MP ultra-wide with a large 123-degree field of view. There are also two 5MP supplementary cameras, namely a macro camera and a depth sensor. The pixel-heavy 20MP front camera can shoot 1080p video at 30fps to make for a rather complete camera setup, especially at this price point.

The Galaxy A42 5G is for those who want 5G connectivity, all-day battery life, and a big screen on a budget. 


Samsung Galaxy A42 5G specs:

  • Display: 6.6-inch, HD, Super AMOLED
  • SoC: Snapdragon 750 5G
  • RAM: 4GB
  • Storage: 128GB
  • Cameras: 48, 8, 5, and 5MP
  • Front camera: 20MP
  • Battery: 5,000mAh
  • Software: Android 10
