Since updating to iOS 18.6 beta on my iPhone 13 ProMax, my battery usage has well over doubled. Also, my phone has become noticeably sluggish and unresponsive.
For instance, after being charged to 100% my phone has dropped to 26% with only 1 hr 2m screen on time and 49m of screen off time. My phone gets noticeably warm to the touch, even through the case.
Any ideas on the cause or any remedy?
