Tecno preparing to bring 'world thinnest' smartphone to India; Check features, expected prices and other details

TECNO is gearing up to launch what it claims will be the world’s slimmest curved 5G smartphone in India. Several media reports suggest that the device may be priced around Rs 80,000, placing it in direct competition with premium offerings from Apple and Samsung.

What are key features?
The Tecno Spark was initially unveiled at the MWC 2025 with the aim to capture the title of “industry’s slimmest smartphone” by delivering a mere 5.75mm profile. For context, that’s over 33% thinner than the Galaxy S25 Ultra, and also nearly 2mm thinner than the iPhone 16, according to the Verge.

Tecno says that the Spark Slim would contain a 5,200 mAh battery, said the report.


The launch at the Mobile World Congress was seen a major competitor to Samsung and Apple who have been planning to bring their thin models as well.

Apple air phone to be out soon
The new Air phone, with probable launch soon, will have a screen that’s around 6.6 inches, slim borders like the iPhone 16 Pro line, ProMotion for smooth scrolling and a standard-sized Dynamic Island interface, according to Bloomberg's Mark Gurman. It also will include enhancements like the Camera Control button. And, despite being far thinner, the model will have a battery life that’s on par with current iPhones.
But the inner workings of the phone, code-named D23, represents a herculean effort by several Apple teams. Skinnier phones require thinner batteries, and that often mean fewer hours of battery life. Apple didn’t want to compromise here, so it sent engineers back to the drawing board to redesign display and silicon components, as well as software, to make the device more efficient.

The company is trimming about 2 millimeters from the phone’s thickness, cutting its depth by nearly 20%. The aluminum back features a single 48-megapixel camera, in contrast to the multiple lenses seen on other models. It will run on a standard A19 chip instead of the higher-end A19 Pro found in the Pro variant and will omit a physical SIM card slot, according the Bloomberg report. An even bigger idea was to make the Air device Apple’s first completely port-free iPhone. That would mean losing the USB-C connector and going all-in on wireless charging and syncing data with the cloud.
