Nintendo has introduced a new feature for the upcoming Nintendo Switch 2 that allows users to cap the battery charge level at around 90%.This feature aims to extend the battery's lifespan by reducing the frequency of the battery reaching full capacity during charging.Regularly charging a battery to full capacity can lead to quicker degradation and loss of charge over time.Similar settings to limit charging are already present in modern smartphones, tablets, and laptops to improve long-term battery health.
