Prevent from Mac battery drain out -Here are some common culprits:
Energy Saver settings: Your Mac’s Energy Saver settings may be configured to sleep, but not to enter hibernation mode when the battery level drops to a certain point. This can cause your Mac to continue using power even when it’s asleep, resulting in faster battery drain. To fix this, go to System Preferences > Energy Saver and make sure the “Put hard disks to sleep when possible” and “Enable Power Nap” options are checked.
Background processes: Some apps may be running in the background and using up battery power. To check which apps are using the most battery, click on the battery icon in the menu bar and select “Battery Usage.” This will show you which apps are using the most power, and you can quit any unnecessary apps to conserve battery.
Wi-Fi and Bluetooth: If Wi-Fi or Bluetooth are left on overnight, they can continue to search for networks and devices, using up battery power. To conserve battery, turn off Wi-Fi and Bluetooth when you’re not using them.
Display settings: If your Mac’s display is set to a high brightness level, it can quickly drain the battery. Try reducing the brightness level, and consider turning on “Auto Brightness” in the Display settings to automatically adjust the brightness based on ambient light.
Battery health: Over time, a Mac’s battery may begin to degrade, resulting in shorter battery life. To check your battery’s health, hold down the Option key and click on the battery icon in the menu bar. This will show you the battery’s condition, and if it’s below 80%, it may be time to replace the battery.
If you’ve tried these solutions and are still experiencing fast battery drain, it may be worth contacting Apple Support for further assistance.
