    I have an S3 and within the last month and a half it suddenly started using mass battery quantity.
    It is not always looking for internet as i am at work and have that function turned off.
    I did however screenshot the battery usage and it seem the Android system and O.S. were excessive
    I am open to any and all suggestions?

    Welcome to Android Central! 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).

    Welcome to AC! I definitely agree with the suggestion by B. Diddy. What I might also suggest is you using an app called 'Better Battery Stats'. Unfortunately, it IS a paid app (Think around $3 now?) - but does provide the most comprehensive information about your phone's battery usage. This includes information about what kernel and partial wakelocks are taking place (basically what is 'waking your phone up to do work'), along with a number of other useful features. You can share your results here and I/someone else can review them and comment.
