New iPhone12 drains battery during long hours of idle time

New iPhone12 drains battery during long hours of idle time(during night) - about 30%-40% everyday.

WiFi is off during this time

Mobile data is off

Dark mode on

Face ID off

Location services off

Battery graph shows zero activity during the mentioned time but the battery drain continues.

This seems to be a serious and generic problem across all 12 models (mini, 12 and Pro).

Any solution for this yet?

Note that apart from this problem, the phone works perfect and battery is top notch during the usage. The drain is specifically only during long hours of idle times.

Thx,

KK

iPhone 12, iOS 14

Hi,

I have a quick update on the above.

After upgrade to iOS14.4, I see that this issue seems to have been fixed. Monitored the over night drain for 3 days post the update and the issue seems fixed, wherein the battery drain is < 3% over a period of 7-8 hours.
