my iphone' 14 pro battery health reaches 93% whitin 8 months is that normal!!!

Battery Health is an inexact figure that varies with usage. The typical Apple Battery lasts for about 2 years, so I would say that yours is very normal. When the figure reaches 80%, it will be time to make an appointment at the nearest Apple Store for Battery Replacement...

Sounds a bit quick IMO.

I don’t believe there is a normal battery usage/health.

My iPhone Pro 12 is at 93% after 2 years of use.

When you have 20 minutes here’s a link to study: iPhone Battery and Performance - Apple Support

Sorry to break it to you but a drop of 1% a month is normal.

Yes
