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.
Do you have a specify way you charge your phone to keep battery health that high? Like do you ever let it get lower than 20% and higher than 80% ? I ask because so many people say that’s how you keep the battery healthy over a year.
Im not only having issues with battery drain, my phone has been overheating just by looking at some videos and playing games using LTE. It’s gets so hot it feels like it’s gonna blow up. Stupid apple. I just got my 12 pro max two months ago and now this.

That doesnt make sense and its now gone from that 99% battery health down to 95 in space of two weeks and fone still over heats with usage like videos makes no sense and then the second update for 14.7.1 just made it even worse and still no option to remove the updates i am highly displeased with there products and i am delighted to move back to samsung after this mobile diminishes.
fast battery drain and overheating
iphone 8
when I use just FaceTime call phone overheating (btw it’s not so hard application)
fix it please
50% drain in an hour after the update! This is unacceptable!
Massive Battery drain after updating to 14.7. New phone and I do this for a living avoid this update!!!!! Apple fix this problem!!!!!!!
How long after the update do you have the massive battery drain?
Genuine polite question please -- you do what for a living?
Not helpful. It doesn’t explain the massive decrease in battery power after installing the latest update. This is ridiculous.
Same problem iOS 14.7 is *****ng ****
same 😖😩
Apple does that every year so, they force you to buy a new device.
I bought an iPhone 12 pro and still it has battery drain issue…
Okay.. will try and give an update tomorrow!
which device are you using? and ios 14.7 is better than ios 14.6 in compare to battery life and heating issue ?
so after 2 days from update ios 14.7 battery life is better than ios 14.6 or not ?
