Performance in Use
The A16s is built around the MediaTek Helio G35, an eight-core processor running at up to 2.3GHz with 4GB of LPDDR4x memory. It handles the everyday essentials smoothly: calls and messaging, email, maps, social media, streaming and casual games. It runs ColorOS 11.1 based on Android 11 with full Google Play access.
Battery life is the headline. The 5000mAh cell carries most users through a full day and more, and the 18W fast charger tops it up quickly when needed. The 6.52" LCD is large enough for comfortable video and reading, and its HD+ resolution helps stretch battery life further.
The 64GB of storage takes a good library of apps and photos, and a memory card slot lets you expand it for music, video and backups. With two SIM slots it suits anyone keeping work and personal numbers on one phone, and it makes a sensible first smartphone or reliable spare.
