Battery is very essential for electronic devices like your mobile phone and laptop. You can configure your computer to enable the remaining battery time so that you can know clearly how much longer you can use it in real time. However, the battery life will be decreased as time goes by. To know the current status of your battery, you should check battery health.
Do You Need Battery Health Check
Battery is an important way to power electrical devices, such as laptops and mobile phones; it is indispensable. The battery capacity determines how long you can use your device after a full charge. However, your battery won’t last forever: the battery could drain in a few hours (if you’re keeping using the device), and the battery charging capabilities will be decreased by time. A battery health check is necessary for you to determine whether you need to charge your battery or replace it with a new one.
How do you check battery health on Windows or Mac laptop? The detailed steps will be mentioned later in this article.
Battery Life vs. Battery Health
Though people tend to confuse battery life & battery health and think of them as the same, there are actually different.
- Battery life: battery life is also known as battery remaining time. It refers to the amount of time that your device could run before it needs to be recharged. It determines how long your battery lasts on a single charge.
- Battery health: battery health is also called battery lifespan, meaning the status of your current battery. It refers to the amount of time your battery can last until it needs to be replaced. It determines how much the battery life decreases over time.
