After updating to IOS 14.7, my battery is draining so fast. In 12 minutes of after fully charged, battery dropped to 89%. My battery health is 99% now.

I'm not ruling out a battery drain problem, but you can't judge battery drain related to a new iOS version within a day of the installation. Every update has some housekeeping to do (varies by update) which takes a lot of cpu time and thus a lot of battery draw, and generates heat. Variables include what needs to be done and how much stuff is on your phone. For example, an update with only some security fixes may only need a few minutes to do its after update chores, while the update a few years ago that changed how each photo was stored and indexed took many hours on a phone with a lot of photos.
For this 14.7 update, on my old iPhone 7 with little on it, it used close to 100% cpu time for several hours and got quite warm. But the next day it was fine. My iPhone 11 went quite a bit faster and also was fine the next day. I didn't try to run from the battery or draw any conclusions about battery draw (or performance, since a lot of cpu usage elsewhere can make the phone feel sluggish) until at least the next day.
When I do updates, I take the case off so heat can dissipate better, insure the battery is fully charged, back up the phone, reboot the phone, then with the phone plugged into a charging block, do the update and then leave it connected to the charger until the phone has cooled down to room temperature for at least a few hours, and then keep it on the charger as much as I can for the next 24 hours.
Question, please -- How long after the 14.7 update finished installing was the two hour period when the battery went down to 74%?
ever since. It’s been 72 hours past now.
Sane boat. Light use and battery now down to 81% after one hour (not continuously either) Used to last much longer with continuous use while I was studying for the Bar!
Should have stayed on 14.3.
Maybe Apple will re-sign iOS 14.3 so we can all downgrade. 🤯
Mine went down twice as fast nothing running! Interesting side note today my battery info said seri used 100% I never used the app
It’s pretty sad the difference. In 14.3 I NEVER got below 50% before bedtime. In 14.7.1, it’s at 50% at 3:30pm with intermittent use.
I don’t have anything installed battery only last 30 min to maybe 2 hrs if lucky!
i have been running the same update for a week! New phone no issues before the update
within 2 hours netflix playback it drops 100 to 35%. its shocking and when you update your device on 14.7.1 , which device are you using now ?
These are all very nice suggestions, but I didn’t drop 1K+ on a new phone so I could go through the same stupid inconveniences I did with my old one. Apple owes us a fix!
i m using 12 pro max i think i m not updating my device on 14.7.1
can we do that? How?
when did you update your device ? and previous you using 12 series model on ios 14.3?
I'm using an iphone 11 (not pro).
THIS IS UNACCEPTABLE. MY IPHONE 12 PRO MAX BATTERY WAS WORKING SO WELL UNTIL THAT UPDATE CAME. NOW MY BATTERY GOES FROM 100 TO 90 IN 30 mins.. ???????!!!!!!!!
did you update your device today on ios 14.7.1? and which ios version your are on before updating?
