battery drops 18% in 10 hours idle, is it abnormal

[bj097]

new iPhone, 12 mini, bluetooth was turned on because I forgot to turn it off, but I have got no bluetooth device, WiFi was OFF, cellular data was ON, not too many apps have been installed so no notification was received. The battery drops from 85% to 68% in a night of sleep, smart battery usage was ON...

does it drop too fast or is it perfectly normal? Was it largely due to that the bluetooth was ON

If it’s a brand new phone it’s normal. It’s indexing/doing background stuff and should improve.

not sure if it's "new" but used lightly for a few days because I am still using my old phone at the same time. I'm not sure if it's a bad battery that is bad on day 1 of born

Well what does the battery settings show for battery app usage? It should tell you what's been using it.

My iPhone 13 PM didn’t start settling down until about 7 days abfter I bought it. I do have 54000 photos and videos and about 200gb of stuff (music, app data, etc).
