You may already know this, but batteries wear out over time. As you use them and recharge them, batteries lose their original designed capacity. You may think that keeping your laptop fully charged is a good thing – but you'd be wrong.




While charging and discharging a battery is the fastest way to wear it out, constantly charging a battery at 100% will also cause faster wear. Fortunately, PC manufacturers have developed a feature that lets you limit your laptop's battery charge to 80% (sometimes even less), so if you use your laptop plugged in most of the time, you can extend its lifespan by keeping it under that threshold. Unfortunately, this feature isn't included in Windows 11 itself yet, but most laptops offer a version of it.

Keep in mind that your BIOS may look different, but the general functionality is usually similar. Also, Adaptive Battery Optimizer is usually enabled by default.
