Bengaluru EV owners — which fast chargers near ORR/Whitefield actually work?

New EV owner in Whitefield. The apps show dozens of chargers around ORR but half are either occupied all day or throwing errors. Which DC fast points near Whitefield/Marathahalli/ORR are reliable for a quick top up? And is home charging basically mandatory here or can you survive on public alone if you have a parking issue in an apartment?
