Hello
Ever since updating to the latest iOS version; I’ve been experiencing significant battery drain on my iPhone. Before the update, I would easily get through a full day of use without needing to recharge. Now, even with minimal usage, my battery is draining much faster than usual. 
I’ve tried basic troubleshooting steps like restarting my phone, closing unnecessary apps, and disabling location services, but nothing seems to help.
I checked my battery usage in Settings, and the screen time is normal, but there are certain background apps using more power than expected, even though I haven’t used them recently.
I’m using an iPhone 12, and the issue seems to have started immediately after updating to iOS 16.6. Is anyone else experiencing this? Could this be a bug with the latest update, or is it a hardware issue? 
I have checked iPhone battery and performance - Apple Support (IN) documentation guide for reference .
Would love to hear if anyone has encountered this and how you managed to fix it!
Thank you !
