Battery drain
Hello
I have an iPhone 12 mini - 2 years old, which I have noticed since updating to 17.0.3 last week, my battery has depleted within a day.
For example, last night, I went to bed at 12 and woke up to a dead battery. Looking at Settings > Battery, at midnight I had 36% battery, and by 7am my phone was dead and switched off. The battery shows no apps running during this time as I generally kill all apps when I go to bed.
I am not sure if this is a coincidence that is started as I updated to 17, or is there an issue with my battery?
Any advice is welcome, thank you.
iPhone 12 mini, iOS 17
