The installed IPS OGS screen is good for home multimedia use or for browsing, having a system without separation between screen and outer glass (OGS) gives us a very good image quality. It also has a correct touch system with 10-point detection.

Cameras, Sensors, Modem and GPS

The cameras of the Teclast T40 Plus tablet are of low quality, have few options in the settings and can only serve us for basic videoconferencing. The 5 MP video conferencing camera is poor, we have very dull colors and the 8 MP rear camera in low light has some pretty dire results. The GPS behaves normally and triangulates the position without problem but it is not very accurate.

  • Cameras: Front 5 MP / Rear 8 MP.
  • Sensors and security: Gyroscope / Accelerometer.
  • Modem and GPS: 4G-LTE SIM + microSD / Basic GPS.

Environment and user experience

We start the Teclast T40 Plus tablet and we see that it comes with the Android 11 system without any additional annoying software. In a basic use for browsing and consuming multimedia content it moves very smoothly and we can use the most common apps without problems thanks to the SoC UNISOC T618 that in browsing heavy webs defends itself well. In the lower area we have the classic Android buttons that we can hide and in the upper area we have the curtain with shortcuts.

  • Launcher: We can change the launcher / Android UI rendered at 2000×1200.
  • Multitasking and access: Multi-task control / Yes it has PiP support.
  • Languages and Google Play: All international Android languajes / Google Play installed.

Network, storage, RAM and ports

We passed the usual performance tests to the memory and internal storage in the Teclast T40 Plus. The internal storage can be expanded using the microSD card reader. The internal storage results are good compared to other tablets in its price range. The Wifi range is quite good thanks to the Wifi ac connectivity and Bluetooth 5.0 connectivity presents no problems.

Power and performance

In terms of power the Teclast T40 Plus has a UNISOC T618 Octa Core chip that has a cluster of two high-performance Cortex-A75 CPUs capable of reaching 2 Ghz and another cluster with six Cortex-A75 that reach a maximum speed of 2 Ghz, in the graphics section we have a Mali-G52 MP3 GPU that is in the medium / low range today. A SoC manufactured in 12 nm that has very controlled consumption. As we can see the good performance and is quite well compared to direct competition especially if we compare the cost of each.

Battery and temperature

The Teclast T40 Plus has a 6600 mAh battery, as we have checked the autonomy is good in a normal mixed use and using the screen brightness at medium level. If we run demanding games the battery drops quickly as normal, but in general we have very normal figures in this range where it is better not to move away from a charger if we are going to use it a lot.

  • Battery: Light use 9 hours, intensive mixed 3 hours / Max Charge 14W.
  • Standby: Connected to Wifi and unused it can last about 7 days or more.
  • Temperature: The back heats up very little.

Streaming services

We ran several tests on streaming services to check how the most popular services work. The Teclast T40 Plus tablet offers us the possibility of watching streaming content in basic quality for Netflix staying in SD+, we are surprised with good quality in other similar services such as Amazon Prime Video or Disney+. Fortunately, the SoC does offer apps on Google Play without complications.

After testing the Teclast T40 Plus tablet we can say that it is an interesting tablet with a good screen and adequate performance for the price. In this tablet we have the SoC UNISOC T618 Octa Core that has a pretty good performance and has a GPU that allows us to run powerful games properly in adjusted quality for very demanding titles. Also good connectivity Wifi aC + Bluetooth 5.0 that behaves well even if the range is not like the top of the range models obviously, the four speakers that mount give us a sound somewhat better than average, we also have audio jack.

The Teclast T40 Plus tablet has a 10.4″ OGS IPS screen that we can use comfortably indoors and has a fairly good color quality and contrast. This tablet for the price has an acceptable battery life, the SoC controls the energy expenditure well, but when we demand performance we can logically omo quickly ocae the percentage.

After testing the Teclast T40 Plus tablet we can say that it offers a pretty good product with a quality screen. A suitable model for those looking for something with content price and valid for games at a good level.
