Root has nothing to do with the battery, memory or developer options, it's basically a single program, su, that an app calls when it needs root access. Some programs that are supposed to root a phone, if used on a slightly different model of the same phone, can cause the problems you're describing. Maybe you should look into flashing the stock ROM back (after backing everything up.)

BTW, Android runs with as much memory (not storage - there's a huge difference) as possible filled up. Unused memory is wasted memory in Android. This is Android, not Windows.
