Help please with battery iPhone

You have not mentioned the age of your phone. These Battery depletions would appear to be quite normal particularly if the phone is an older model. The typical Apple Battery lasts 2 years with normal use. When Battery Health reaches 80%, it will be time to make an appointment at the nearest Apple Store for Battery Replacement.

If you have been using your phone for a year.....12 months.....I would expect the Battery Health to be in the 88-90% range. At 95%, your battery is doing significantly better than average. Lucky you.

Normally, Battery Health will decline at rate of about 1% a month and yours is at .5%.
