Battery and Charging

The Galaxy A42 5G comes equipped with a powerful 5,000 mAh battery that delivers impressive endurance, often lasting up to two full days with moderate use.

This balance between excellent battery duration and relatively modest charging performance makes the phone reliable for extended daily use, though not the fastest option for those seeking quick top-ups.
