After a busy August that saw Google, Vivo, Xiaomi, and others launch new devices, this month promises a packed lineup for smartphone buyers. Most of the September launches—Realme 15T, TECNO POVA Slim 5G, and Oppo F31—sit in the mid-range segment, balancing performance, battery life, and AI-powered cameras without hitting flagship prices.
Samsung’s Galaxy S25 FE and some Oppo Pro models borrow premium touches like AMOLED displays and multi-camera setups while keeping prices accessible. At the high end, Apple’s iPhone 17 and the Gaia AI Phone stand apart with cutting-edge chips, advanced cameras, and specialised features.
Across the board, battery life, usability, and software innovation are defining the new devices, making September an interesting month for both practical users and tech enthusiasts.

Oppo hasn’t reinvented the cameras or design here, but the Pro+ is tipped to feature Snapdragon 7 Gen 3 power, while the other two stick with MediaTek chipsets.
