The Tecno Spark Slim is just 5.93mm thick—making it the world’s slimmest 3D-curved smartphone. It weighs only 156g, yet feels premium thanks to its fiberglass back and Gorilla Glass 7i front. It’s also IP64-rated and MIL-STD-810H compliant, meaning it can handle splashes and light drops. Compared to the Spark Pro Plus (6.5mm, 160g), the Slim is noticeably lighter and more pocket-friendly. This design is perfect for users who want a stylish phone that doesn’t bulge in their pocket or weigh down their hand during extended use.
The Spark Slim features a 50MP AI primary camera and a 13MP front shooter, both optimized for cty and color accuracy. It includes dual rear LED flashes and a status light ring that doubles as a visual cue for calls, charging, and notifications. AI enhancements improve low-light shots, portraits, and HDR scenes. While the Spark Pro Plus shares the same 50MP sensor, the Slim’s software tuning and LED ring give it a creative edge—especially for content creators and selfie lovers who want standout shots without needing extra gear.
You get a 6.78-inch AMOLED display with 1.5K resolution and a 144Hz refresh rate. It peaks at 4500 nits brightness, making it one of the brightest displays in its class. Whether you’re outdoors or binge-watching indoors, visuals remain sharp and vibrant. The Spark Pro Plus matches this panel spec-for-spec, but the Slim’s thinner bezels and lighter frame make it more immersive and easier to hold for extended viewing sessions. It’s ideal for users who stream, scroll, or game for hours.
Powered by the MediaTek Helio G200, the Spark Slim runs Android 15 with HiOS 15. It comes with 8GB RAM (expandable to 16GB via memory fusion) and 256GB storage. There’s no microSD slot, but the internal storage is ample for most users. Compared to the Spark Pro Plus, which shares the same chipset and RAM, performance is nearly identical. However, the Slim’s lighter OS skin and better thermal design make it feel snappier in daily use—perfect for multitaskers and casual gamers.
The Spark Slim supports 2G, 3G, and 4G LTE bands, with dual SIM slots for flexibility. It includes Wi-Fi, Bluetooth, GPS, FM radio, OTG, and even NFC—a rare find in this price segment. Whether you’re sharing files, tapping to pay, or navigating offline, it’s got you covered. The Spark Pro Plus offers similar connectivity, but the Slim’s faster Wi-Fi handoff and better signal optimization give it a slight edge for users in areas with spotty coverage.
This device features a physical gyroscope, an infrared remote control, a side-mounted fingerprint sensor, and face unlock capabilities. The IR blaster allows you to control TVs and appliances—perfect for students or travelers. The gyroscope enhances AR apps and gaming. Compared to the Spark Pro Plus, which lacks the IR blaster, the Slim offers more utility in everyday scenarios. These thoughtful extras make it more than just a phone—it’s a smart companion for work, play, and home.
The 5160mAh battery supports 45W Super Charge, delivering a full charge in under an hour. It easily lasts a full day of heavy use—streaming, gaming, and multitasking —without issue. The Spark Pro Plus features a slightly larger 5200mAh battery, but charges at a slower rate of 30W. For users who dislike waiting, Slim’s faster charging is a game-changer. Additionally, battery health optimization ensures longevity so that you won’t need a replacement anytime soon.
