Hello,
In one month, my battery health dropped from 100% to 97%. Can anyone suggest some tips? It has only 131 cycles, and the battery is draining like this :(. I always charge between 20-80% and use low power mode when it goes below. Could it be because of the charger? I don’t have an original adapter.

Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical makeup, storage conditions, exposure to heat and cold and about a dozen other factors mean that every battery ages differently. Battery aging is not a linear (straight line) and degrades at different rates as the chemicals in the battery age and other factors mentioned above. Apple expects your battery health to be at 80% after 24 months. If your battery health misses that expectation, contact Apple Support.
Please review the Apple Support articles on battery optimization. It contains the best current practices for battery charging.
