Within six months, Tecno returned to the market with another affordable 5G phone to the Bangladeshi market - the Tecno Spark 40 5G. The new model is based on the increased popularity of the brand within the entry-level 5G segment, which includes a faster Dimensity 6400 chipset and a more refined 120Hz display to provide a more everyday experience. 

Tecno has also been keen on battery life with a huge 6000mAh battery. Nevertheless, certain trade-offs are still present. The entry-level model is also limited in storage capacity, and the charging rate is lower than competitors. Nevertheless, the Spark 40 5G will be offering tremendous value to the first-time 5G consumers.

An In-Depth Review on Tecno Spark 40 5G

Tecno Spark 40 5G is a sleek affordable smartphone that gives its users the latest generation connectivity without necessarily spending a lot of money. It has a 6.75 inch HD+ screen with a smooth 120Hz display and is powered by the MediaTek Dimensity 6400 processor with 4GB RAM to ensure good day-to-day use. The gadget has a 50MP camera in the back, an 8MP selfie camera and a huge 6000mAh battery that supports 18W charging. This review explores the Tecno Spark 40 5G’s design, display quality, performance, and price in Bangladesh.

Box Content

This is what you get inside the Tecno Spark 40 5G Design box:

• Tecno Spark 40 5G Smartphone
• 18W Charger
• USB Type-C cable
• Protective Case
• SIM ejector tool
• User manual

The Tecno Spark 40 5G comes in a compact box with the essentials neatly arranged. Inside, you’ll find the phone itself, a pre-applied screen protector, a transparent silicone case, a SIM ejector tool, and the usual documentation. Notably, Tecno has skipped including a charger in the box, following the recent industry trend to cut costs and reduce waste. Users will need to purchase a compatible 18W charger separately if they don’t already own one. Overall, the box content feels minimal yet practical for daily use.

Design & Build Quality

The Spark 40 5G makes a very good step forward in terms of design over previous low-end models. It has a body that is approximately 167.7 x 77.9 x 7.99 mm making it have a slim profile at the price. The back and frame are made of plastic, but the front is glass- this is to keep the weight down without losing the shape. 

Among them is its IP64 rating, which implies that it is dust-tight and can withstand splashes of light water, which is unusual in this price range. That is equivalent to increased life in daily use - one reviewer reports a drop resistance of up to approximately 1.5 m.

The finishing and decoration is also enhanced. The back panel has colours such as Sky Blue, Ink Black and Turquoise Green and the camera set up as well as the flat-edges make it seem more upscale. The buttons and ports are normal and in the right place: the side-mounted fingerprint sensor (easy to use) has the power button and the volume rocker above it. USB-C, 3.5 mm audio jack and stereo speaker are located at the bottom edge. 

At that, you will have certain trade-offs in terms of budget. The plastic construction is not as high-end as metal or glass on the more expensive phones, but the styling is fully grown up. Screen bezels are still more visible than the premium models. However, considering its price, the Spark 40 5G offers a balanced construction that is oriented towards a high-end touch without exceeding the budget.

Display

A huge 6.75-inch IPS LCD display with a 120 Hz refresh rate is a huge advantage of the Spark 40 5G, as it is much easier to scroll through and touch the screen is more responsive. The resolution is HD+ (720 x 1600 pixels) and thus the screen size is large, but the sharpness (pixels per inch) is not as high as most Full HD competitors. 

The display is quite reasonable in its size and refresh rate, which is why it can withstand the bright daylight and indoor light in Bangladesh, which makes reading a text or browsing the phone easier than on a lot of more affordable phones. However, since it is HD+ and not Full HD, you might find the detail to be a bit less sharp when viewing high-resolution video or reading fine print. The 120Hz definitely contributes to the experience becoming more flowing than the usual 60Hz screens.

Reproduction of colour is average in the segment, but not best. Due to the low-cost panel type and resolution, you will not achieve the richest contrast and the richest blacks that are provided by the high-end AMOLED displays. In the case of media-intensive users (movies, HDR content) it implies that the display is not excellent but rather good. Conversely, the big 6.75-inch display and the smooth refresh are good options in daily activities such as reading news, social media, or casual gaming.

The Spark 40 5G is a 5G model with one of the bigger and smoother displays available in a budget 5G model in Bangladesh. It is a reasonably balanced choice between everyday use and reading work, but in case you value ultra-sharp detail or the quality of the display, you might have to upgrade.

Camera

The Spark 40 5G has a 50 MP rear main sensor with a dual-LED flash. That would be a solid headline on a paper of a budget 5G phone in Bangladesh, and during the day the results are reasonably up to the task.

Daylight Photo:

In bright light you have high-resolution results, average detail and acceptable dynamic range. The big sensor assists in taking sufficient light in Bangladeshi outdoor environments (bright sun, a bit of haze) and indoor images. It has official specifications that it deals with backlight and night scenes, which are restored more accurately. With that said, given that it is still a budget-phone sensor, you will be able to see a few trade-offs: finer details (especially in texture/complex patterns) will become blurred, and noise will creep in during more difficult conditions.

Low-Light & Night Mode

In this case the Spark 40 5G is doing well in its category. The large sensor and LED support imply that even in low light conditions you can achieve usable shots: the colours are relatively true-to-life, and the light-capturing is sufficient to work in the nightBangladesh environment (street lamps, indoor indoor lighting). Two reservations: first, the detail is considerably less than in daytime. Second, it is a low-end device that does not have the advanced multi-frame stacking or incredibly fast lenses that are found on more expensive models, so it will have poor performance in situations where light is extremely limited.

The dual-LED flash is useful to fill models, but may cause rather harsh lighting effects on faces or bright reflections in darker scenes. Nevertheless, at the price that the low-light camera commands, it is above average in the market.

Selfie Camera

There is a 5 MP shooter on the front as per a number of spec sheets. It implies that selfie performance is highly geared towards good enough to use on social media/casual and not high-quality portrait-level performance. During the day the selfies appear acceptable with a good skin tone and clarity to chat or post. In low light, though, there will be blur, loss of detail and poorer performance than the rear camera.

In most of the listings, the highest recording mode stated in the video is 1080p, 30fps. It is sufficient to use as a social device, but it is not going to give you 60fps or 4K capture, so you may feel constrained in your ability to capture a lot of high-quality motion footage.

Performance & Software

The Tecno Spark 40 5G is also powered by the MediaTek Dimensity 6400 5G+ chipset, which is a significant improvement over the Helio G36 of the Spark 20C. This new processor is also the key to making the 5G connectivity available in the Spark series at a reasonable price in Bangladesh. Although it does not have as many 5G bands as the more expensive devices, it provides impressive real-world speeds, and users will probably feel that their download speeds are fast and their latency is low in high-coverage 5G areas.

The Spark 40 5G base model has 4GB of RAM and 128GB of internal storage, which can be expanded with the help of a microSD. This setup suffices with everyday activities like web surfing, social media, and messaging applications. The phone is usually responsive, although heavy multitasking can sometimes bring some slight lags. The Dimensity 6400 chipset is also more efficient in performing CPU-intensive tasks compared to the previous generations, which can be used in moderate load.

The Spark 40 5G is good in its segment in benchmark testing. It scores well in AnTuTu and other synthetic tests, usually beating its rivals such as Itel P55+ and Realme Narzo N63, and competing with slightly more expensive models.

In the case of gaming, such games as Battlegrounds Mobile India (BGMI) can run well on medium settings, but frame drops might be evident in the case of longer sessions. More relaxed games and less demanding play, on the other hand, are problem free.

On the software front, the phone is based on Android 15 with Tecno HiOS skin, with a user-friendly interface with some added features like an IR blaster to control domestic appliances and NFC to make digital payments. In general, the Spark 40 5G is a decent product offering a combination of performance and software options to users in Bangladesh who want to have a powerful 5G phone at a reasonable price.

AnTuTu Benchmark & GeekBench Score

The Tecno Spark 40 5G provides a good benchmark performance in its category, as it can be seen that it is an affordable 5G smartphone.

The Spark 40 5G scored an average of 4,14,009 in the AnTuTu 10 benchmark, and the results are as follows:

CPU: 84,479, GPU: 35,504, Memory: 67,616, and UX: 67,813. Such scores show that the device is good in daily activities and in moderate multitasking conditions. 

In the case of Geekbench 6, Spark 40 5G scored 501 in single-core and 1,410 in multi-core, indicating that it is not as powerful as more expensive models, but it can be used in everyday tasks and light gaming. 

Battery & Charger

The Tecno Spark 40 5G will have a large 6,000mAh battery, which will be able to last the whole day to support activities such as streaming, gaming, and browsing. 

In terms of charging, the device has 18W fast charging. Nonetheless, this is a relatively low charging rate as compared to some of the competitors in the low-end market. An example is the 45W fast charging in the Realme Narzo N63 and Itel P55+ that can save a lot of time on charging. It is worth mentioning that the Spark 40 5G is not packaged with a charger, which is becoming a trend among smartphone companies. This exclusion implies that you will have to buy a compatible charger on its own in case you do not have one.

To conclude, the battery capacity of the Tecno Spark 40 5G is quite impressive to use, but the speed of the charging process and the lack of a charger could be the aspects to be taken into account by the prospective purchasers.
