I am late to this conversation, but I have a question: both my iPad Pro and my iPhone 11 Pro seem to get slightly shorter battery life between charges. Has anyone else noticed this? Perhaps it is because Javascript runs slower?

Have you enabled Lockdown mode on both devices? Then that's almost certainly the cause. Without the JIT you're going to be burning a lot more CPU cycles running JavaScript.
