A fun fact is, the user pointed out that he has been using the same power adapter that came in the box. Further, he said that he has not used any other charger in the time being, but still facing the strange problem.

Battery and Charging issue is not a new challenge for OnePlus smartphone owners. However, this is something that seems to be irritating yet more humorous. Ironically, a user said that it’s funny how they say alien objects. NASA can’t detect aliens but the OnePlus smartphone did.


For your information, the notification reads that the Alien object or liquid detected. Unplug the charger, make sure the charger and the USB Port are dry and clean, restart the device, and plug it in again.

Probably, the only problem that is visible with the statement is the charging port is dirty and requires some cleaning. This could avoid such prompts from appearing again and again.
