What commenters say

• Charging a MacBook Pro on the right side may improve performance and reduce overheating due to better heat dissipation.
• The design of the laptop's cooling system is flawed, leading to overheating issues when charging on the left side.
• The use of USB-C ports has introduced new problems, such as overheating and compatibility issues, that were not present with older port designs like MagSafe.
• Some users have found that using a laptop stand can help to improve airflow and reduce overheating, but a true heatsink design is needed for optimal performance.
• The placement of internal components, such as the SSD chips, may contribute to the overheating issue when charging on the left side.
• The OS may not properly throttle the CPU when the right side of the laptop overheats, leading to performance issues.
• Using a right-angle USB-C cable or a dock with a built-in cable management system can help to reduce clutter and improve airflow around the ports.
