The Apple M1 silicon macbook’s long battery life is one of its USPs; however, some users have found that when they use their macbook with an external monitor, even when the laptop is on sleep mode, overnight, the laptop’s battery drains, which over time will reduce the overall health and longevity of the battery.
This is primarily due to the graphics card in the laptop needing more power to process images and productivity on the second screen, which, in turn, generates a lot of heat and puts additional strain on the battery.
This can be mitigated to some extent by opting for a smaller, lower resolution monitor, ensuring the laptop is plugged into the power supply to make use of smart battery-saving features, and ensuring the laptop is not constantly charging, which can be achieved by using a laptop stand.
