Why is iphone email slow?

I send a photo via iPhone and it takes up to three days to get it. I send the exact photo same size via android and it's instantaneous. I need to get these photos to my doctor right away.

Hi there

Please try this

Keep the Mail App Open: Unlike Android, iOS aggressively pauses background data processing to save battery. When sending a large photo, do not close the Mail app or lock your phone screen until you hear the "swoosh" sound confirming it has been sent.
Turn on Background App Refresh: Go to Settings > General > Background App Refresh and ensure it is turned On for the Mail app.
Turn Off Low Power Mode: If the battery icon in the top right corner is yellow, your phone is restricting data transmission. Go to Settings > Battery and toggle off Low Power Mode.
Remove and Re-add the Email Account: Glitches in the outgoing SMTP mail server can cause emails to hang in the Outbox for days. Go to Settings > Apps > Mail > Mail Accounts, select your account, tap Delete Account, and then re-add it.
