Technically it does not make any sense. your device switches to host mode when you plug in an usb stick or sth else. such devices won't deliver any power to your device. but on the contrary such devices need a power source or won't do anything. if your device don't deliver power to a USB stick you won't be able to read/write any data of/to it.
That doesn't make any sense. So no power in USB host? What about the hundreds of devices that do it, like a cheap fire tv? Many devices would be rendered useless without this ability.
Reason phones dont have the feature is due to having a battery afaik.
You know what host mode means? Your phone enters the host mode when plugging in an USB stick or sth else that gets connected by an OTG adapter. Should the USB stick charge my phone??
If you connect two phones then the used cable/the order they get connected will decide which one enters the host mode and powers the other device.
...and if you connect your phone with a PC/laptop/TV/Bluray/Hifi then your phone gets charged because your phone isn't in host mode then.
Do you know what a charging OTG cable is? USB stick and charging... What are you talking about?
Using OTG and charging can work simutaneously, technically... But generally devices don't support that... When you connect OTG, phone goes to host mode and provides power to external device... When a charger is connected, it goes to client mode and can receive power... There are hubs out there that have USB ports, as well as charging port that claim to charge your phone while using devices connected... But they don't work on all devices... I had a tablet long time ago, and it did not support that... It would either charge, or go to OTG mode, but not both....But some folks with different tablets claimed to have that hub working both as OTG as well as charger simultaneously... As far as tablets are concerned, my guess is that this feature could be available more frequently since the need to use keyboard/mouse/other external devices is more for tablets than it is for cellphones... So I think it would not be possible with OnePlus 9's kernel...
