I use Android USB debugging to debug my own app. The app has high power requirements since it stresses the camera bus a lot. The power consumtion is so high that the phone's battery discharges during USB debugging and the phone turns off at some point. When I run the app without USB debugging and use the regular wall charger (2 Ampere) the battery does not discharge and stays at 100%. This leads to the conculsion that my mainboard can not deliver enough power to the phone. Is there any way to increase it?
What I've tryed so far:
- Using a cheap USB hub with an external power supply, it hat no effect at all
- Checked all BIOS settings related to USB power delivery, they had no effect either
- Tried different USB ports
Is there maybe a special Cable that uses Power delivery from Source A and the datalines from Source B?
Please Note:
- The App has to use that much power! Reducing the power consumtion isn't possible without loosing performance. (Display is already at minimum brightness and Wifi etc. are turned off)
- The phone needs to be connected via USB to the Computer to transfer data. So debugging over Wi-Fi etc. are no options either
- The phone uses USB 2.0 with a micro USB connector
