iPhone 13 mini battery drain overnight

There was a community post about this in October 2021; unfortunately the answers did not provide a solution.

Suffering the same issue now I wonder about any solution. Watching the battery status or caring about energy saving methods is the last useful imho and does not offer any help.

Situation is, that the iPhone loses 15-20% battery life overnight will just idling. Energy saving mode activated(means also no background updating). Battery’s usage shows no apps consuming! Battery health is at 97%.

Any help / idea on that?

Thx

iPhone 13 mini, iOS 15

Thanks again, Lafeef.

Although none of that helps me from the position I ask the question from.

My point is not to demand for anything about how to save battery which I´m of course aware of, but to get a grip on the problem or hints from people experiencing the same issue. Obviously the battery drains for no comprehensible reason..

Well, so I’ll wait a while for further community thoughts before perhaps calling upon apple regarding this matter then.

I can confirm after the first nighttime with iOS 15.4 running, that the drain issue did not appear again.

So perhaps some unknown interferences within iOS causes that drain.

Presumably mentionable: The iOS Update was done via Mac (taking the more comprehensive iOS package).

I appreciate the fast input. Summarizing, you recommend to a) Update the iPhones iOS, b) Report that issue to apple and c) learn something about battery usage.

Well, that honestly doesn’t get me anywhere further than I am…

Thank you for your reply!

See the articles I sent you above ⬆️

and I advise you :

Leave your phone plugged in and charging overnight. Once the battery is charged the phone will switch to using power from the power supply. Once the power supply is removed the phone will switch to using battery power.

Do not make a habit of closing all apps. It takes more system resources to restart an app from scratch than it does for a suspended app to pick up where it left off.

Make sure optimized charging is turned on: Settings > Battery > Battery Health > Optimized Battery Charging

Your battery will chemically age over time, there is nothing you can do to avoid this.
