iOS 14.7.1 battery drain

Question

iOS 14.7.1 battery drain

I am experiencing a excessive battery drain on my iPhone 12 Mini after upgrading to iOS 14.7.1.

After charging my phone to 100%, the battery drops to 18% in less than 12 hours without any usage at all. Now I have to turn off GPS, wifi, bluetooth, apps running in the background manually in the settings to make my phone last the minimum of ~6-8 hours. Its no longer a reliable phone for me.

Prior to the update I could easily leave my iPhone 12 Mini untouched and unplugged for 2-3 days without any issues.

When the support here in Sweden did a hardware scan they found no issues. All apps are updated.

Please fix this issue.

iPhone 12 mini, iOS 14

SOLVED: The FaceID sensor was causing the phone to have massive battery drain.

Turned FaceID off and my phone battery was back to normal.

Apple changed my phone to a new one and now it seems to be working as normal with no more than 5% battery drain during standby (8+ hours).

I did reset my phone, updated it and read back my backup. Still no signs of better performance, sadly.

Look at this image from my iPhone 12 Mini. Absolutely no usage and it dropped 50% in 6 hours.

My Samsung S9, to this day, only needs a charge to 100% every 2-3 days on normal usage.

I think I will return my iPhone. Sadly this is also my first apple device since the iPod touch with the exact same problem back in like 2009.

This article helps me in absolutely no way. I see you are a top contrubitor, simply by spamming KB's in threads. The battery health is 97%. Also - you do realize the phone is literarily brand new?

My Note8 outperforms my iPhone and it was literarily released late 2017.

Here is a long thread about this issue. Some users found that reloading the iOS version helped. https://discussions.apple.com/thread/252997312?page=1
