Same here after upgrade iOS 14.3.

it seems something wrong in the low power module... check the screen shot below. Nothing is running when I am sleeping and the background refresh is disabled. Battery health is 90%. It is really URGENT PROBLEM! Please advice! I do not want to get late from work because the iPhone is out of battery in the morning and the alarm is not working..

This does not help at all. I upgraded to 14.3 last night and charged my battery to 89%. Then unplugged the charger, put my phone on flight mode, went to bed. I woke up to a completely drained battery. My battery maximumum capacity is 80%, which does not explain the complete drain on flight mode. Something is wrong with the update. Please fix this issue.

I am having the same issue. I updated to iOS 14.3 two days ago and have noticed constant power drain. I am plugged in right now charging while using, and lost 4% while reading this forum and posting this response.

Same issue with mine, updated to ios 14.3 and now my battery is draining like crazy, got the new iPhone 12 and still with 100% battery health, one night it got drained like 20% wifi on, lowbattery mode on, dark mode on, do not disturb on

Battery draining while talking on the phone even while plugged in. This happened in an earlier update, sorry don’t remember which one . Battery is not being drained by my app unless there is something running in the background. Hope someone can sort this out. Battery was fine before this update
