I woke up to a notification on my screen saying iOS had updated to 14.4.2. My iPhone 7 had changed the setting to allow automatic downloads. I always have it set to manual.
My battery dropped from 100% to 79% in 30 minutes. I checked all my settings and all of the usual battery drain culprits were off: background app refresh, location, etc. I restarted and that didn’t help. Now it’s taking so long to charge back to 100%

Hello,
Hmm, there is always additional processing with a new version of iOS. You can check the standard steps for short battery life:
1) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.
2) Check “Battery Health” in the link:
iPhone Battery and Performance
3) If all else fails, consider a battery replacement:
Good luck.
Your device needs a replacement battery. That's why you had the "draining" issue.
The update only contained security fixes and did nothing to your old battery.
What is its health percentage?
It was 79% capacity. I had no issues yesterday and today it just drained so fast.
