If battery saver is on, you're gonna see it in the bar. No way around it. Even custom status bar icon themes are going to do that. You're being anal. Maybe stop staring at the single icon that doesnt match a theme and the screen off time will save you, seriously.
As i basically have full control it is definitely possible. I just wanted to know if there already was a way. If not im just gonna learn how and do it myself.
