You won't be able to charge the phone if you're using the IOIO in device mode, since it is always the host that supplies power to the device and not the other way around. When you say "OTG" I'm assuming you mean that the phone is the host and the IOIO is the device. Otherwise, I don't see a reason why the phone wouldn't talk to the IOIO according to its specs. Some people have found issues with the IOIO as host in OpenAccessory mode which may be relevant to you: https://github.com/ytai/ioio/issues/119
