iOS 15.4.1 BATTERY DRAIN

I have an iPhone 12 that was updated to IOS 15.4.1 and now my battery drains away from minor use. I can look at Twitter or Facebook for a few minutes and the battery will drain by 8%. This used to never happen. Yesterday when I went out at lunch my battery went from green to red. My phone usage hasn’t increased at all, but my battery is now draining at record rates since the IOS 15.4.1 update.

I have an iPhone 12 mini and before the update I had substantial battery life but since updating to IOS 15.4.1 I’m only getting 6 to 7 hours of battery life by 11 am I’m out of juice. What gives?

I too updated to the same iOS. Since 21-APR-2022 my iPhone11 has been getting hot and the battery has been draining very quickly… I updated at the last update, so I have no clue why this is only happening now. Please can Apple advise on how this issue can be resolved and quickly… thank you

Dear all,

it is been informed that after 15.4.1 IOS update. Battery is draining is fast. Can you release a previous pervious version some features in new IOS. So that we might get a relief from battery drain problems

I also have this problem, I leave the phone with 60% charging in the morning 0%
