Laptop batteries degrade over time, but MacBook users can mitigate this by adjusting charging settings to stop at 80 percent. This tweak slows battery deterioration, according to a WIRED guide. The advice highlights the chemical nature of batteries and their inevitable wear.
Batteries in devices like MacBooks are chemical components that naturally degrade with use, leading to reduced performance over time. Owners of MacBooks often notice diminishing battery life as the device ages. However, it is possible to slow this degradation process by modifying the Mac's charging options to limit full charges.
The WIRED article explains that forcing the MacBook to charge only up to 80 percent helps preserve the battery's longevity. This adjustment addresses the common issue where batteries 'lag in performance as they age.' By implementing this setting, users can extend the effective life of their laptop's power source.
The guide, published on March 8, 2026, provides practical tips under keywords including how-to, Apple, Mac, tips, batteries, and apps. It emphasizes that such human-made components wear down inevitably, but proactive steps like this charging limit offer a way to manage it.
