Smart Charging in Windows 11 limits your battery to 80% to reduce long-term wear — ideal if you keep your laptop plugged in most of the time.
Lower brightness, enable Battery Saver, close unused apps, turn off Bluetooth and Wi-Fi when idle, and switch to dark mode — five small changes for noticeably longer battery life.
Wi-Fi and Bluetooth constantly scan for signals in the background — toggling them off via Win+A Action Centre saves meaningful battery during offline focus sessions.
Background apps silently drain your battery — disable them via Settings → Apps → Installed apps → Advanced options → Background app permissions → Never.
