I have the latest Kit Kat version on my Nexus 5. Ever since I've owned this phone, I haven't been able to figure this out, but it's never really bothered me enough to dig into this any further. I figured now is about as good of a time as any to ask you all if you're experiencing this as well. I have the battery % number displaying on the top-left in the status bar on my phone. I have not done any mods to the stock ROM nor did I make any changes to have that at the top left. In fact, I would love to get rid of it so I could get a battery app that has more options on it. But whenever I get the app, it just adds another icon on the status bar instead of replacing this one. Anyhow, does anyone know where the setting is in the OS for this particular battery % number that is displayed for me on the top-left of the status bar by default?
