Compare A3 2016 with A5 2016 Battery Usage: Enhanced features and Android Core Apps

Hi, I have A3 2016 (SM-A310F) with detail software info:

1. 5.1.1 Android version
2. A310FXXU2APC5 Baseband version

I have compared with A5 2016 (SM-A510FD) battery usage, but I found something weird with my A3 (screen shot available below).

There is something different if I compare with A5 battery usage which doesn't contain Enhanced features and Android Core Apps that use huge battery percentage. Samsung A5 can live longer than my A3 because of this.

My Question is, what this item used for and how to disable it?
