Batteries play a crucial role in electronic devices like smartphones and laptops. You can adjust your computer settings to display the remaining battery time, helping you understand precisely how much longer you can use it in real-time. However, over time, battery life tends to decline. To assess your battery's current state, you should perform a battery health check.

Do You Need a Battery Health Check?

Batteries serve as vital power sources for devices such as laptops and mobile phones, making them essential. The battery capacity determines how long your device can operate after a full charge. Nonetheless, batteries don't last indefinitely; they may deplete within hours of continuous use, and their charging efficiency diminishes over time. Conducting a battery health check is vital to decide whether you need to recharge your battery or replace it with a new one.

How do you check battery health on Windows or Mac laptops? Detailed instructions are provided later in this article.

Tip: Be cautious when performing operations on your laptop, as even minor errors can lead to data loss and system failures. In case this happens, consider using data recovery software. MiniTool offers guidance on laptop repair and recovery.

Battery Life vs. Battery Health

Although people often confuse battery life and battery health, they are distinct concepts.

• Battery life: Also referred to as battery remaining time, it indicates the duration your device can function before needing a recharge. It reflects how long your battery lasts on a single charge.
• Battery health: Often termed battery lifespan, it signifies the present condition of your battery. It pertains to the total time your battery can operate before replacement. It measures the gradual reduction in battery life over time.
