Automatic powering on and not staying powered off
#3
I think this is the way Allwinner intended it to work, what happens on Android phones or tablets is that they boot into a 'charger image' instead of the real OS, this just displays the battery icon/charge status, and they do that by checking the power-on reason register (REG 02H: Power up/down reason register in the AXP803).
So what really is needed is imho to extend u-boot in a way to handle that case and configure the ANX7688 as well...
