Battery life is another area where these models differ slightly. In rigorous testing, the MacBook Pro M4 retained 74% of its battery after a full day of use, compared to the Air’s 68%. Despite its higher performance capabilities, the Pro benefits from a larger battery and an efficient cooling system, which contribute to its longer runtime.
