Good afternoon! I bought a new MacBook m1 Pro 14.2, 1.5 months ago, since then I have recharged the laptop only 9 times, but during this time the battery condition has dropped abnormally fast from 100% to 93%, and continues to decline, who has faced a similar problem, is it possible to solve it somehow?

Thanks!

Normal, I see no issue.

You do not have to micro-manage the battery charging/health/or percent, let the software work for you.

Your a Battery is covered under your hardware warranty. Apple will not entertain any request unless it has dropped below the 80% health.

No one said battery health it is a linear progression.

The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you optimize your battery charging and extend the working life of your battery by reducing the cycle count.

BHM notice ~1 yr the Battery health has increased over time see col.2, battery cycle count col.5

example:

Keep in mind Apple only just recently showed the Battery Maximum Capacity in macOS so people have never seen how the Lithium Batteries degrade over time. In fact, the Maximum Capacity can fluctuate up & down. For example....a battery with a Full Charge Capacity of 4,315 mAh (battery for MBPro 13" 2017). A 200mAh fluctuation results in a fluctuation of 5%. A 200 mAh fluctuation is not unusual for an Apple Lithium Battery. I only begin to worry about the battery once the fluctuations get to 400 - 500 mAh.

Design Capacity = 4,315 mAh = 100%

Full Charge Capacity = 4,115 mAh = 95%

Before Apple exposed the Battery Maximum Capacity value, the only people who may even have noticed were the users utilizing a third party app such as Coconut Battery to monitor their batteries health.

Unfortunately even most Apple techs are not aware of these specific details. I only discovered it when I analyzed my organization's Apple laptops when people were complaining of battery related issues, but macOS showed the Battery Condition as Normal and the Apple Diagnostics reported no issues either. Apple only cares about when macOS shows the Battery Condition is "Service Recommended", or when the Battery Cycle Count is over 1,000 cycles, or the Apple Diagnostics report a battery failure.

You can take the laptop to an Apple Store to be examined, but they won't do anything unless one of those conditions I mentioned are met.

My recommendation to everyone is to ignore the battery information until the battery no longer performs to your expectations to see if it merits a replacement. Some people may be happy with the battery performance even when the Battery Maximum Capacity is below 80%....it all depends on a user's workload & expectations.
