How to Calibrate your Laptop Battery - Mac and Windows!

Summary

In this video, the presenter walks you through the process of calibrating your laptop battery to ensure accurate charge readings and improve overall battery health. The calibration involves charging your laptop to 100%, keeping it plugged in for two more hours, then draining the battery completely until the laptop shuts off. After waiting five hours, you charge it back to 100% uninterrupted. This simple yet effective process can help prevent issues like unexpected shutdowns and battery drain. The presenter recommends calibrating your battery once every month or 45 days. This advice applies to both Mac and Windows laptops, and a similar process can be applied to smartphones and tablets.

Takeaways

• 😀 Calibrating your laptop battery ensures your operating system has an accurate reading of the battery's charge level.
• 😀 Battery calibration helps prevent issues like unexpected shutdowns and excessive battery drain.
• 😀 You can calibrate both Mac and Windows laptops with the same process.
• 😀 To calibrate, start by charging your laptop to 100% and keeping it plugged in for an additional 2 hours.
• 😀 Once the laptop is fully charged, unplug it and use the laptop normally to drain the battery.
• 😀 Allow the battery to drain completely until the laptop shuts down on its own.
• 😀 After the laptop shuts down, leave it off for 5 hours to ensure the system recognizes the battery is fully drained.
• 😀 After waiting 5 hours, plug the laptop back in and charge it uninterrupted from 0% to 100%.
• 😀 Battery calibration should only be done once every 30 to 45 days, not every time you charge the laptop.
• 😀 This process helps optimize battery performance and improves long-term battery health.
• 😀 Calibration isn't just for laptops—smartphones and tablets also benefit from calibration, though the process differs.
