Why does Android system use so much battery

I just bought a note 4 from at&t and I was looking at the battery chart and after I drop to 20% the android system has used 27% and the screen has used the second most and its only used 9%. I am coming from a iPhone so I don't know anything about this. Sorry if it's a simple fix I am just clueless.

Re: Why does Android system use so much battery

Welcome to Android Central! The real question is how your overall battery life is. Android System and Android OS will both tend to use a fair percentage of battery, because it's the system, which always has to do something. The screen will also be a top user, since the screen always requires a good amount of energy to function.

Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
