Just because they're using more proportionally more battery than the screen doesn't necessarily mean they're misbehaving. Since the battery stats reports percent usage, the percentage of one item may go up if the percentage of another app goes down. So in other words, if you happened to be using the screen less often during that battery cycle, the other items using battery will end up using a greater percentage than before--but it doesn't mean they're using absolutely more battery than before.
If you're still concerned, show us the following screenshots after discharging to 20-30% from a full 100% charge, in normal use, with no charging in between:
1. The main Settings>Battery screen.
2. The fullscreen battery graph screen, to see the total Awake time and cell signal strength.
3. The Screen category, to see the total Screen On time.
4. The Cell Standby category, to see the Time Without Signal.
