Battery usage

Did you know you use 34% of my battery. Could use some changes. Not like it’s Maps. Others then that love it.plus why does face does Facebook use is up to 440.6MB and going up on iOS why so space usage? It’s redundant and your the only app that does it.your app size only says 300.08 MB well as you can see you have passed it. It needs to ?.
