Tecno S1 budget Android smartphone with 1GB RAM & 4-inch display introduced


Almost every smartphone OEM in Nigeria has its own budget series of smartphones, but not many go below the 1GB RAM & 2000mAh battery level, resulting in super-25k smartphones. Some, like the iTel with its A series, still go beyond that level, and Tecno Mobile has joined the gang with a new smartphone called the Tecno S1.

The Tecno S1, which marks the debut of the new Tecno S series, was recently introduced in the Nigerian market, and though it’s not yet available for purchase, its specifications are already known, and oh boy… what could be low-end than this!

Tecno S1 Key Specifications

  • 4-inch display.
  • 512MB / 1GB RAM.
  • 8GB ROM.
  • 2MP rear camera.
  • VGA front camera
  • 1500mAh battery.
  • 3G & 2G network connectivity.
  • Android 6.0 Marshmallow.

Software & Connectivity

Like most devices that are as low-end as this, the Tecno S1 runs on Android 6.0 Marshmallow out of the box.

The smartphone would be available in single and dual micro-SIM variants, both supporting major 2G (GSM & EDGE) network bands and the HSDPA 2100 3G network band in Nigeria. If you were expecting 4G, then you need to re-read the introductory portion of this post.

Design & Display

If you need a sure indication that the S1 is only suitable for those that haven’t used a smartphone before or purchase it to serve the role of a spare tyre, just take a glance at it; it comes with a compact 4-inch IPS LCD display which has a 800 by 480 pixel resolution.

Just imagine watching movies or playing games on such a small screen estate. At least it’s a touchscreen device; if it weren’t I wouldn’t be writing about it at all.

The smartphone has the basic budget smartphone design; plastic body with polycarbonate removable back panel, and large bezels (especially at the top and bottom) with capacitive navigation buttons.

Memory & Performance

The Tecno S1 is powered by a quad-core MediaTek MT6580M processor that is clocked at 1.3GHz. That’s pretty generous on a budget, as is its 1GB of RAM for multi-tasking. There’s a variant with 512MB of RAM, though.

The smartphone comes with 8GB of internal storage space for storing files and app data, and you can slot in a microSD card with a capacity of up to 32GB if things get stuffy on the inside.

Camera & Battery

The Tecno S1 offers some photography relief with a 2MP camera and dual-LED flash system at the rear, and a 0.3MP camera at the front for selfies (if the images produced could be called that).

The smartphone packs a 1500mAh battery which should last up to eight hours on average use.
