so i have the iphone 14 plus, before that it was the iphone 13 pro. i got this 14 in january, and this is currently my battery health. the 13 was at 98% battery health after 2 years of owning it, i only got a new phone bc i shattered the screen beyond repair on the 13. anyway, is this normal? to be at 90% after less than a year ?

edit to add. i do spend A LOT of time on my phone. My screen time averages 15-18 hours per day every week because of my job, ie. (door dash, spark delivery).
