After my phone updated to the iOS 18 Beta, my battery no longer last past 2pm. Before the Beta, my phone would still be at 40% by 11pm. It drops down as soon as I unplug it. It gets really hot with everything I do on it. Hopefully this gets fixed and my battery quits having issues. This same thing happened to my phone back with the iPhone 7. Ended having to trade it in due to battery not last past 12pm.
