That’s normal. The number is just an estimate, to begin with… That said, a drop of approximately 1% per month is about average. Note that the drop is NOT linear.


All rechargeable batteries lose their ability to hold a charge with time and use. It’s normal. Batteries are consumables. When the battery health drops to 80%, it should be replaced.

Don’t stress over it.
