Do you have an iPhone 15? If so what kind? Pro? Max? Thanks!!! I’d love to try the Watch OS 11 beta but since these are my daily drivers (yes I know the deal) I want the best odds of avoiding the huge battery drain issues some with both have reported. I’m fine with the typical battery drain you get from betas early in the process but what I was reading seemed to be excessive and I only recently (as of Watch OS 10) started installing betas in my watch because of the process involved in rolling them back. So far staying with the latest iOS 11 beta and watchOS 10.6 beta has served me well in the battery department. It’s no worse than usual and I’ve been beta testing iOS for years now.
I have the 15 Pro Max, and a Series 8 41mm cellular. So far, the drain is definitely more than stable builds, i'd say around 10-20% more depending on what i'm doing. If before i'm ending the day with 50% then it would be 30-40% now. Not that bad considering it's literally the second developer beta that's not even meant for regular users. Bugs are also not that annoying but they're there.
I don't use the watch with cellular tho, my carrier here blocks cellular from beta devices so my watch works like the non-cellular version of the series 8. If you like to give a shot I would say just keep in mind the worst case of 20% more battery consumption (in my experience), and the fact you can't downgrade it. Also always keep a backup, if there's any problem, just do a reset and restore from backup, that'll usually solve the issues with the betas.
