I purchased my MacBook Air m3 in January 2025 till now after use on battery and plugged in both ways I just got 2% of battery health degradation in November month it is reached to 93 percent health why ?
is there anything to concern my charge cycle are somewhere around 75
MacBook Air 13″
Ignore the battery health information until the battery is no longer performing to your expectations. Until recently, Apple never showed users the "Maximum Capacity" value of their batteries. I have been monitoring the battery values for many years now & quickly learned the Apple Lithium Batteries have their "Maximum Capacity" fluctuates up & down all the time (even with a brand new battery). A new & healthy battery can have this value deviate by +/- 5% very easily if closely monitored, but macOS doesn't update this value all that often.
People who have used Coconut Battery have learned when reviewing the Coconut Battery app's battery history over time that the "Maximum Capacity" and Full Charge Capacity (FCC) values fluctuate up & down. FCC is just a different way of reporting the battery capacity (it is generally the information the battery provides to the OS & the OS converts it into a value which makes sense to users). Unless that 7% drop was instantaneous in one moment, that drop is not enough for me to even consider a battery to be bad (it is close, but not close enough) much less gradual drop to 7%.
Unless you just want to learn how your battery works & behaves over time, it is best to just ignore the battery information completely until you have an actual problem which affects how you use the laptop. If you want to observe the battery information.....fine, but just watch & learn how it behaves.
Plus I think since late 2024 I think Apple changed what they consider a worn out battery since both macOS & the Apple Diagnostics no longer report a battery problem until the battery's "Maximum Capacity" is below 75% (I'm not even sure of the exact percentage since I haven't had a battery that can consistently remain below that point long enough to confirm).
Take a look at the following two screenshots of Coconut Battery's history for my MBPro M1 2020 model (IIRC, the laptop was purchased around Nov/Dec 2020):

FWIW, it is the nature of rechargeable batteries. I have an M1 MacBook Air that I bought when It came out in late 2020. By mid 2021 its capacity was down to 91%. Today in 2025, it is at 90%.
Some batteries can drop initially a fair amount and stay there a long time, some can hold max capacity for a long time then drop rapidly, some just decline linearly, etc. It is just the nature of the beast.
Just use your Mac and as stated previously, when you no longer get the amount of workable battery time then get concerned.
"is this normal that in just few days Mac battery heath drop 5 percent and in previous 10 months only 2 percent"
-------
Yes. It is normal. My iPhone 13 Pro Max Battery Health is down to 84%. It took 4 years to get to 90%. Then, it dropped to 84% just a week later. It hasn't changed since.

"Why is my MacBook Air's battery health degrading so quickly?: I purchased my MacBook Air m3 in January 2025 till now after use on battery and plugged in both ways I just got 2% of battery health degradation in November month it is reached to 93 percent health why ? is there anything to concern my charge cycle are somewhere around 75"

Thank you for the screenshot.
About Battery Health Degradation:
Unfortunately, there is no way to determine why, nor when, the Battery Health degraded. You are fine, until it gets to 80%. Expect the Battery Health to fall 1-3% just after usage when opened from the original packaging.
About Battery Cycle Count:
You have charged this 75 times, and this 75 has to do with the times it was fully-charged and then discharged. So, this would indicate you have charged this to full, and downgraded it 73 times since.
Why has
