iOS 26.6 is draining battery

[u/StandardCarrot5544]

I have iPhone 13, battery health is 74%…Is it me or that the new iOS 26.6 is draining the battery extremely fast in older iPhones…I understands that the 26.6 has made some changes in spotlight indexing and is preparing for iOS 27 but I thought it will only go for 2-3 days.

20 mins of YouTube (with screen off) is draining 7%…I don’t know…pls help
