Hello Mr-sha,

We understand that the battery is draining rapidly on your new MacBook Air. We'd like to provide you with a few steps that can help optimizing your battery life and diagnose the issue:

"Use settings that optimize battery life

Laptop battery life is affected by how your Mac is configured and how you're using it, but you can improve battery life by using settings that help conserve energy.

Check Battery settings

From the Apple menu  in the menu bar, choose System Settings (or System Preferences), then click Battery. To see additional settings when using macOS Ventura or later, click Options.

Battery settings related to power modes or energy modes affect energy use, as do settings that enable your Mac to wake for network access or optimize video streaming while on battery. Availability of these and other settings varies by Mac.

Check Displays settings

Choose Apple menu  > System Settings (or System Preferences), then click Displays. To see additional settings, click Advanced.

Displays settings related to brightness affect energy use, including settings that enable your Mac to automatically adjust brightness, compensate for ambient light, or slightly dim the display while on battery. Availability of these and other settings varies by Mac.

Diagnose battery issues

To help diagnose battery issues, check the health and charging status of your battery.

Check Battery Health

Choose Apple menu  > System Preferences (or System Settings), then click Battery. The Battery information shown here includes Battery Health:

• Normal: The battery is functioning normally. 
• Service Recommended: The battery's ability to hold charge is less than when it was new, or the battery isn't functioning normally. You can safely continue to use your Mac, but if your battery needs service or its lowered charging capacity is affecting your experience, get your battery evaluated at an Apple Store or Apple Authorized Service Provider, or contact Apple.

In some earlier versions of macOS, battery health might be reported as Replace Soon, Replace Now, or Service Battery, and might appear in the battery status menu instead of Battery settings: Press and hold the Option (or Alt) key while clicking the battery status menu  in the menu bar. 

Some third-party apps also report battery health conditions, but the data they report might not be accurate or conclusively indicate diminished system runtime. It's best to rely on the battery-health information reported by macOS.

Resolve battery-charging issues

The battery status menu  in the menu bar shows how much charge your battery has, whether it's currently charging, and whether your display or any apps are using significant energy. When your Mac is connected to power and using optimized battery charging in macOS Big Sur or later, this menu also shows information such as whether charging is paused and when your battery will be fully charged. 

Occasionally your battery might not show a full charge (100%), even after the power adapter has been connected for a long time. This is optimized battery charging, which helps prolong the overall life of the battery. If charging is on hold and you need your battery to be fully charged sooner, choose Charge To Full Now from the battery status menu .

If your battery isn't charging, make sure that you're using the correct power adapter for your Mac. If the power adapter isn't rated for at least the wattage that your Mac requires, it might not charge your Mac reliably. If you're using the correct power adapter, make sure that the power adapter isn't at fault:

• If your USB-C power adapter isn't charging
• If your MagSafe power adapter isn't charging

If your battery still doesn't charge:

• Shut down your Mac, close its lid for 30 seconds, then try to charge again.
• If you're using an Intel-based Mac, it might help to reset the SMC.

Use Apple Diagnostics

The tests performed by Apple Diagnostics include tests for battery issues.
