In today’s tech-driven world, smartphones are no longer a luxury – they’ve become an everyday tool essential for work, study, and even leisure. Not every user needs flagship specs or a high price tag; for many, the priority is a device that is affordable, simple, and reliable.

In the budget smartphone segment, true “workhorses” are emerging – devices that cover basic needs like calls, messaging, social media, and simple apps. These models play a key role, making the digital world accessible to everyone, regardless of budget. The Cubot A40 fits squarely into this category, aiming to combine minimalism, affordability, and practicality. It doesn’t promise to break performance records, but it aspires to be a quiet, reliable companion for everyday use. Let’s see whether this simple smartphone can meet those expectations.

Positioning and price
The Cubot A40 is an ultra-budget smartphone priced at around $100. It is available in gray, black, and lilac color options.

By adding $12 to $14, you can get a budget-friendly bundle from Cubot’s official AliExpress store that includes the smartphone along with one of their smartwatches – either the U1 or the C28.
Package contents
Inside the Cubot A40 box, you’ll find all the essentials to get started: a charging adapter with a USB-A to USB-C cable, a user manual, and a SIM tray ejector tool. As a nice bonus, the package also includes a clear plastic case that covers the back and top and bottom edges, as well as a protective screen film, allowing you to safeguard the display from day one.

Design
The Cubot A40 has a simple yet tidy design. Its styling is clearly derivative, largely borrowing from the Apple iPhone, which arguably makes it a suitable look for an affordable Android smartphone.

The back of my test unit features a matte light-lilac finish, which helps the phone stay secure in hand and reduces fingerprints. At the top, there’s a slightly raised transparent plastic section housing the three main camera lenses and the LED flash.

The side edges are also light lilac and made of plastic with a metallic finish, giving the phone a slightly more premium look than its price suggests.
On the right side, you’ll find the volume and power buttons, which are easy to locate by touch. The left side houses a hybrid tray for either a microSD card and one SIM or two SIM cards without a memory card.

The bottom edge houses the microphone, a USB-C port, and a speaker, while the top edge includes a second speaker.
The front-facing camera is a small, centrally placed “teardrop” above the display, giving the screen an almost uninterrupted, modern look.

In summary, the smartphone’s design is simple and straightforward – unfussy, yet both pleasant and practical.

Display
The Cubot A40 features a 6.88-inch IPS LCD display with a resolution of 720×1640 pixels. The image isn’t particularly sharp, with a pixel density of 260 ppi, but it’s adequate for everyday use. A notable bonus is the 90 Hz refresh rate, which makes scrolling and animations appear smoother than on most budget devices.

The display supports multitouch and responds quickly to input. It offers wide viewing angles, decent color reproduction, and adequate contrast. Even outdoors, the screen remains bright and readable, making the phone easy to use in a variety of conditions.

Hardware and performance
The Cubot A40 is powered by a UNISOC T606 processor, paired with 4 GB of RAM and an ARM Mali-G57 MP1 GPU – a fairly standard setup for budget smartphones. It’s worth noting that the processor is somewhat dated. Occasionally, I experienced brief stutters lasting one to three seconds, which weren’t resolved even by expanding RAM by up to 8 GB using internal storage. Outside of these occasional hiccups, the Cubot A40 performed reasonably smoothly and responsively for everyday tasks.
The smartphone isn’t designed for gaming, as indicated by its entry-level GPU. In practice, only the simplest games run smoothly, though this is still enough for casual time-killers during a bus ride or while waiting in line. Well-optimized titles from Gameloft also perform fairly well, even on this modest hardware.

The Cubot A40 lacks a fingerprint scanner but does support FaceID. In my experience, however, facial recognition was inconsistent and only worked reliably from certain angles, meaning I often had to enter a PIN or password.

Cameras
The Cubot A40 features a triple rear camera setup and a dedicated front-facing camera for selfies. The main 48 MP sensor delivers decent photos with good detail in well-lit conditions, especially at close to medium distances. Landscape shots, however, tend to be less impressive.

The 2 MP ultra-wide sensor helps capture panoramas and landscape shots, while the additional 0.03 MP sensor is likely intended for depth effects in portrait mode, though I didn’t notice any significant impact. The 16 MP front camera produces reasonably sharp and detailed images, making it suitable for selfies and video calls.
In everyday use, the camera performs adequately at a basic level. However, low-light performance is noticeably poor due to the lack of stabilization and the budget-level sensor and optics. Don’t expect high-quality photos from the A40 – capturing a decent shot or video requires ideal lighting and very steady hands.

The main camera can record video at 1080p, though the quality is modest, with average detail and smoothness. There is also a slow-motion recording mode available.
Overall, the cameras are sufficient for basic tasks, like photographing objects or documents, but for truly high-quality results, a phone with a better camera would be more suitable.
Sound
The phone doesn’t include a 3.5 mm headphone jack, so you’ll need to use the USB-C port, wireless headphones, or rely on the built-in speakers. There are two speakers – one on the top edge and one on the bottom – which provide stereo sound when watching videos or movies. Overall, the audio is adequate without major distortions, though at higher volumes some rattling can occasionally be heard.

Software
The Cubot A40 runs a clean version of Android 15, providing access to standard Google services and the Google Play Store with its wide selection of apps. The interface is simple and easy to navigate, with settings that allow you to adjust the display, apply themes, and manage notifications and app behavior.
Users can also adjust volume and brightness, enable or disable dark mode, and configure security and privacy settings. Additional options include power-saving modes and control over background app activity.
The Cubot A40 supports NFC, allowing contactless payments or other functions without needing a card or cash.
Battery life
The Cubot A40 is equipped with a 5100 mAh battery, which, combined with its modest processor, provides enough power for 8–10 hours of active use. In my experience, using the phone for about four hours a day – messaging, watching videos, and listening to music – allows me to charge it only once every two days. However, there’s no fast charging, so a full charge from 5% to 100% takes roughly an hour and a half, making overnight charging the most practical option.

Conclusions
The Cubot A40 is an affordable smartphone with a large 6.88-inch display featuring a 90 Hz refresh rate and a straightforward, clean Android interface. It’s well-suited for everyday tasks like watching videos, browsing social media, and using basic apps.

Of course, the model has its limitations – it lacks a headphone jack and a fingerprint scanner. Still, for its price, the Cubot A40 is a solid option, particularly as a first phone for a child or as a simple, easy-to-use device for an older adult.
