Hi,

I got my phone last November 2021 and today (June) the battery health has dropped to 95%.

within a week 2% dropped.

I just do not know what needs to be done.

I have optimized the battery, turned off background refresh. Still, I don’t see anything helping.

please advise on charging methods too.

There's absolutely nothing wrong with your phone, nothing needs to be done. The average decline in battery health is about 1% a month, so, you're almost exactly where I'd expect you to be. It's important to note that the reported decline in battery health is not linear. Sometimes it will stay the same for months, then drop several points. It will also re-calibrate when you do an iOS update.

Batteries are consumables. Nothing you can do will change that.
