It is not using "20 something percent" of your battery.
Of the actual battery usage in the time frame under consideration, the Android OS used 20%. The Screen used some other percentage; the phone and Wi-Fi and Maps and etc used some other percentage. All of these combined used a total of 100% of the battery usage thus far.
The reason Android OS is at 20% is simply that you are not doing much with the other parts of your phone. If you never use the phone, maps, browser, and so on, you might very well see Android OS rise to 60% or even 80%. OTOH, if you talk extensively on the phone, you will see it rise to the top of the list and other items - like Android OS - sink lower.
I took the phone off charge at 100% and did not touch it for about 5hours and the battery was down to about 70 - 75% with Android OS at the top saying 30% is that normal because i didn't use the phone?
