I just sent a report to Apple regarding the battery drain. Just thinking about having to deal with this for two weeks makes me want to downgrade to beta 2 or directly restore to 26.1. The downside of restoring is that I'll lose my eSIM, and it's a real headache to recover it with my carrier. I'll also lose some bank transactions that are only in Apple Pay. But if the battery life doesn't improve by Friday, I'll have to decide which option to choose over the weekend.
As of today, I don't see iOS 26.2 as being a good version at all. Apple has a lot of work and it seems like they're always on vacation. Between starting the beta cycle a week late and now taking another week off, it looks like they'll delay the release of iOS 26.2 because the Release Candidate, which should be the next beta version in the first week of December, has to fix a lot of performance and visual issues that I don't know if they'll be able to address. Also check the reported bugs; they all have more than 10 reports, but none have been fixed yet haha
