In "Activity Monitor," you can see which apps are consuming the most power and close them.

If your iPhone is connected to your Mac for charging, it will drain your MacBook's battery. For instance, if you're transferring photos or files between your iPhone and Mac, the constant connection can quickly deplete your battery. Once the transfer is complete, unplug the iPhone or use a separate charger to save your MacBook's power. You can use Airdrop or maybe the later iPhone Mirroring function in macOS Sequoia to do it.

What's more? Starting with the 2018 MacBook Air, Apple introduced a single-fan design. With the 2020 release of the M1 chip version, the MacBook Air further evolved to a fanless design. This design reduces power consumption and heat generation, helping to extend battery life. So keep your MacBook cool.
If you really need a longer battery life, carrying a high-capacity portable power bank (like a 30k mAh one) is a great option. This way, you can recharge your MacBook even when you’re away from a power outlet.
Dark Mode not only makes your screen easier on the eyes in low-light environments but also saves a bit of battery life.
