iPhone shutting down
my iPhone 7 has started shutting down on 30% since I did the latest update. My battery is showing peak performance and the phone is just over a year old.
I’ve done a reset but it’s still happening

Hello,
These are the standard steps for short battery life:
1) Have you tried a restart? If not, do it now.
2) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.
3) Check “Battery Health” in the link:
iPhone Battery and Performance
4) If all else fails, consider a battery replacement:
