Reset Battery Preferences

Wrong Energy Saver or Battery Preferences may cause your Mac to consume extra power and energy, thus leading to the MacBook Pro battery drain problem.

Click the battery icon at the top right Apple menu bar and select Battery Preferences. Or, go to Apple icon > System Preferences > Battery.
Click on the Battery tab from the left column. Then, move the slider to the left side to reduce the length of time it lasts before your display turns off.
Click on the Power Adapter tab, then tap on Energy Mode to open up its drop-down menu. Check if High Power is on. If it does, click on Automatic or Low Power.

Note that High Power Mode is currently available on a 16-inch MacBook Pro with an M1 Max chip. So if your MacBook Pro does not support it, simply ignore it and move on.

Turn off Bluetooth

If you don't use Bluetooth all the time, close it now. Keeping the Bluetooth on will expend your energy too. Click the Bluetooth icon at the top Apple menu bar or open it in System Preferences. Then, turn your Bluetooth off.

Or, if you fail to determine and find which apps are eating up your Mac's energy and power, you can use Activity Monitor to find them out:

Press the Command + Space keys to open Spotlight Search. Then, type Activity Monitor to open it.
Under the Energy tab, find the app that conserves too much energy.
Select it and click the close button at the top to quit it.

Fix 3: Reduce screen brightness

The display of your MacBook is also one of the items that take away your battery energy.

You can reduce your screen brightness by pressing the F1 key on an older MacBook or clicking the sun icon on the Touch Bar for a modern MacBook Pro.

Fix 4: Unplug unnecessary connected external devices

Sometimes, you connect your AirPods, iPhone, or other external devices that consume battery power to your MacBook Air or MacBook Pro. That leads to your laptop battery draining so fast.

Once you disconnect these devices, your MacBook battery will last longer.

Fix 5: Update your applications

If this MacBook Pro better drain fast issue occurs after you update your Mac, and you can't troubleshoot it with the above ways, you can try to update your applications on your device.
