why does my battery health draining so fast?

Hi rcfrancine,

To help solve your issue, let's maximize you battery life by completing the steps listed here: Get help with your Mac notebook battery - Apple Support that are also listed below.

Optimize your battery life

Your notebook battery life depends on your computer's configuration and how you're using the computer. Here are some settings and steps that you can take to get the most from your computer’s battery.

Check Battery preferences

The Battery pane in System Preferences has settings to help improve the battery life on your Mac notebook. To view Battery settings, choose Apple menu  > System Preferences, click Battery or Energy Saver, then select Battery in the sidebar. 

The example above is from macOS Monterey. Some features such as Automatic graphics switching and Power Nap aren't available on all Mac notebooks or versions of macOS.

For maximum battery life, use the following settings:

• Turn on “Slightly dim the display while on battery power.” This setting lets your Mac adjust the display brightness to 75% when you unplug the computer from power.

• Turn off “Enable Power Nap while on battery power.” This setting prevents your Mac from checking for mail or other iCloud updates during sleep which improves standby time.

• Turn on “Automatic graphics switching.” This setting lets MacBook Pro models with multiple graphics processors automatically switch between them to maximize battery life.

• Turn on "Low power mode." This setting reduces energy usage to increase battery life.

Adjust display brightness

By default, your display automatically adjusts the brightness to conserve power. If you turn off automatic brightness, you should turn it back on later to preserve battery life. To set the brightness automatically, choose Apple menu  > System Preferences, click Displays, then turn on ”Automatically adjust brightness”. Learn how to adjust your brightness manually.

Best regards.
