Over the last 10 days, my MacBook Air M2 has had heating issues during normal day-to-day work. No extra work or heavy usage, and when he heats the battery, it drains(5 hours) much faster than usual.
The MacBook Air (M2, 2022) was first introduced in 2022 making the battery 4 years old
Apple Batteries are rated for 1000 Full Battery Cycles or 80% of the Amperage Capacity before it needs servicing or replacement
The biggest enemy of batteries are prolonged periods of excessive Heat or Cold ( refer to "environmental conditions " ) later in this reply
The Apple MacBook Air (M2, 2022) uses passive cooling, meaning it has no internal fan ( making it a fan-less computer).
It dissipates heat through a combination of the chip’s efficiency, a heat spreader, the aluminum chassis, and thermal throttling when needed.
The Apple Inc. M2 chip is built on an efficient ARM-based architecture with high performance-per-watt. Compared with traditional x86 laptop CPUs, it generates less heat for the same workload.
That efficiency is the main reason passive cooling is practical.
Inside the laptop, the M2 SoC (system on a chip) is connected to a metal heat spreader, a graphite pads/sheets,and thermal interface materials.
These components spread heat away from the tiny chip across a larger surface area so heat does not concentrate in one hotspot.
The MacBook Air’s aluminum chassis absorbs and radiates heat into the surrounding air.
Without a fan, the laptop relies on normal airflow around the device:
This is much quieter than active cooling because there are no moving parts.
The computer is rated to perform under the follow environmental conditions
Running the computer or storing the computer for prolonged periods of time outside the above created norms.
Can or will have a negative effect on the battery run-time. Quote " it drains(5 hours) much faster than usual. "
