The first developer preview version of the Android 11 system has been released. Some new features of the system have been discovered. Android 11 can now detect that the mobile phone is not properly placed on the wireless charging pad and give tips.
According to 9to5Google, when your Android phone (Pixel 4 tested by netizens) is not aligned on the wireless charger, the Android 11 system will display a warning on the lock screen to tell the user to readjust the device.
How does the system know that the phone is not aligned with the charging pad?
The specific principle is not clear at present. Most likely, the system will detect the charging speed of the device. When the power is small, it will guess that the phone is not aligned properly.
With the Qi standard, the device can charge even if the phone is not fully aligned on the charging pad.
