Top Highlights
- The Tecno Spark Slim has been listed on the company’s official website showcasing a 5.93mm thin body, a 6.78-inch 1.5K 3D AMOLED display, the MediaTek Helio G200, and a 5,160mAh battery with 45W charging.
- Tecno promotes it as the world’s slimmest 3D-curved smartphone.
Overview
Tecno previewed the Spark Slim during IFA 2025 and later published its product page, giving a clearer picture of the company’s design direction for its mid-range lineup. The focus here is not raw horsepower but thickness reduction, display quality, and practical everyday performance.
While pricing and rollout markets were not publicly confirmed at launch, the company is positioning the Spark Slim as a thin, lightweight alternative in the crowded mid-range segment.
Design and Build
A 5.93mm ultra-thin frame
The Spark Slim measures 164.2 x 75.9 x 5.93mm, putting it well below the thickness of most mainstream phones. Tecno uses this figure to support its “slimmest 3D-curved” claim for the 4G variant.
A very thin frame often comes with engineering trade-offs. To maintain battery capacity and thermal efficiency, manufacturers usually adjust internal layout and component stacking. Tecno states that it managed to keep structural stability and durability intact.
Finish and materials
The phone is listed in Slim White and Cool Black, with a clean rear panel and slightly curved edges. Tecno also mentions a “mood light design” element intended to give the device a more stylish identity.
Display
6.78-inch 1.5K 3D AMOLED
The Spark Slim carries a 6.78-inch 1224×2720 1.5K AMOLED panel with a 144Hz refresh rate.
This combination targets smoother animations, vivid colors, and higher clarity than standard Full HD displays.
Curved edges and brightness
The 3D-curved profile gives the display more immersion and can help with gesture navigation. Tecno highlights daytime brightness and color accuracy, though real-world testing will determine how well the screen handles outdoor use.
Performance
MediaTek Helio G200
The Helio G200 is built for routine smartphone tasks rather than heavy AAA gaming. Users can expect steady navigation, quick app loading, and consistent performance in social media, communication apps, and moderate gaming.
Daily usage expectations
The chipset’s efficiency should pair well with Tecno’s refresh-rate management, which lowers the 144Hz rate automatically to save battery during static use.
Memory and Storage
Tecno lists models up to 12GB RAM + 256GB storage.
RAM expansion can raise total effective memory to 16GB by converting part of the internal storage into virtual RAM.
This system is not as fast as physical RAM but helps the phone keep more apps active without stutters.
Cameras
50MP rear camera
The Spark Slim includes a 50MP main camera with dual rear flash.
Tecno’s software suite adds AI functions such as AI Eraser for removing unwanted objects in photos.
13MP selfie camera
A 13MP front camera handles video calls and everyday selfies.
It isn’t aimed at pro-level portrait shooters but should be reliable for routine use with Tecno’s image processing.
Battery and Charging
5,160mAh battery + 45W
Despite the 5.93mm thickness, the phone houses a 5,160mAh battery. Tecno claims a 0–100% charge in about 57 minutes using 45W fast charging.
The device also supports 10W reverse wired charging, useful for topping up earbuds or accessories.
Real-world speeds will differ based on temperature, cable quality, and device condition.
Software and AI
The phone runs Android 15 with Tecno’s AI stack, including:
- Ella assistant
- AI Eraser 2.0
- AI writing and AI search tools
These additions are meant to offer simple on-device tools for editing, productivity, and quick interactions.
Connectivity and Audio
Key features include:
- NFC
- Bluetooth
- GPS
- 4G LTE
- USB-C
- FM radio
- IR blaster
- OTG support
Audio is handled by dual speakers with Dolby Atmos, which should provide clearer and louder sound than single-speaker mid-range phones.
Durability
The Spark Slim carries an IP64 rating, meaning it is resistant to dust and light water splashes.
Tecno also mentions military-grade shock resistance, though details of the testing standard were not specified in the early product information.
Very slim phones sometimes experience thermal buildup during extended recording or gaming, so users may want to wait for independent testing to understand heat control under load.
Who It’s For
- The Spark Slim is best suited for:
- people who prefer very thin, lightweight phones
- users who watch a lot of video content
- social media users who appreciate a curved AMOLED panel
- everyday users who need dependable performance and long battery life
It is less suitable for:
- heavy gamers
- creators who rely on advanced camera hardware
- users who prefer metal or thicker frames for durability
Price and Availability
Tecno showcased the Spark Slim at IFA 2025 and published its product listing, but no confirmed global price or rollout regions were shared during early announcements.
Regional availability will depend on Tecno’s distribution plan, which often targets Africa, South Asia, and select European markets first.
