How Does Battery Capacity Impact Performance?
Battery capacity significantly impacts the performance of devices by influencing how long they can operate before needing a recharge.

High-quality plastics or rubberized materials can enhance grip and impact resistance, ensuring that the case not only protects the device but also feels good in hand.
