The TECNO Spark Slim and TECNO Pova Slim 5G will be launched at IFA Berlin in just a few days. Both are expected to be the world's thinnest entry-level phones. So, what should you know about it?

The Samsung Galaxy S25 Edge, which was recently released this week, could signal the return of ultra-thin smartphones. Featuring a remarkably slim 5.84mm profile, it is one of Samsung's thinnest to date. Alongside other models, it represents a resurging shift in 2025 toward thinner, lighter phones. Are ultra-thin smartphones making a comeback in 2025?

Looking to unveil more interesting concepts, Tecno also recently announced their Spark Slim concept phone which will be demoed at MWC 2025. At a mere 5.75mm, it's gunning for the title of the world's thinnest smartphone with a 5200 mAh battery (perhaps because the vivo X5Max still holds the overall record at 5.1mm).
