Yes and no. You are correct that things may take *minimally* longer initially, because there is a bit more logic involved in class loading, and patching.(*) This should be in the order of milliseconds though, and is only relevant when loading a class for the first time.
I could very well imagine that it's a psychological effect of having the patches activated for the first time: You are looking closer at how your device behaves. And you notice that everything is a bit sluggish in the beginning. This is normal, and a non-patched Kindle behaves exactly the same. Because classes are loaded on demand, the very first access to some functionality requires a bit more time. Try it: uninstall jbpatch, and reboot. Your subjective experience will pretty much be the same as with jbpatch installed.
To your second question: none of the patches published so far have any effect on battery life(*). I am 100% sure of this, because I know the system in and out.
(*) Ok, let's split hairs
: jbpatch may consume a few million CPU instructions more, over the average device uptime. So assuming an average uptime of 20 days, you might lose a minute or two of battery time
- but not more. In fact, some patches (TTS, no-ads) might even (minimally) *extend* battery life, because they replace complex calculations by a simple "always true"/"always false" result.
