Disable wireless charging during drain, usb charging, and charger stress test - vendor.disable.wlc 1 If a device was put on dreamliner and shut dwon(drain out), it powered up by DC_CHG and then shut down(0%) again - boot (by DC_CHG) continuously. To avoid this symptom, limit wireless current_max as 75000 after devices boot up - persist.vendor.limit.wlc.current=1 How to verify: adb shell setprop vendor.disable.wlc 1 adb shell cat /sys/class/power_supply/wireless/online >>>> 0 adb shell setprop persist.vendor.limit.wlc.current 1 adb shell cat /sys/class/power_supply/dc/current_max >>>> 75000 Bug: 179094447 Test: set the property manually and query the result from file node.
