May 2021. iPhone 7+. Power drain
iPhone 7+ was 90% powered up. Drained to “red” overnight while powered Off completely. Plugged it in & in one hour it is now @ 26% power. Never happened before. What advice does anyone have?

Hello,
Start with 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:
Good luck.
