Arduino USB port to connect with a android phone and also charge the android phone

Using Arduino Project Guidance
1

I have a MKR WIFI 1010 Arduino, i use USB serial to communicate with the android phone. I pass some data from the Arduino to the android device and vice versa. The Arduino is power up with an external power source.

I have BLE and WIFI in MKR but the requirement is to use USB serial for communication, i cannot use BLE and WIFI.

Now the problem is, the battery on the android device is draining very fast.

Cannot we use the Arduino to charge the android phone instead of draining its battery. I saw that
MKR Arduino can output 5V.

What type of battery are you using ?

Is it a 9V PP3 style battery by any chance ?

How is this problem related to the IDE 1.x? Topic moved to a more suitable location on the forum.

I think OP means the battery of the phone :wink:

Quite possibly

I await the answer with bated breath

EDIT - reading the initial post again I see that you are correct
