Yes me too. I got my zenfone 6 just 2 months ago. Experienced this kind of problem last week.
Whenever I used the included Asus Charger and Cable, the phone started charging for several seconds then stopped. Then automatically started charging again, the stopped. My phone vibrates all the time because of this "connected disconnected" loop problem.
At first I thought it was just cable problem. But I tested myself using this method,
- tried charging using another fast charging port (my Aukey Charger has 2 ports : QC3.0 and not fast charging port) using the Asus Cable -> have the same issue as above
- tried charging using not fast-charging port (the same Aukey Charger) using the same Asus Cable -> my phone is charged, never disconnected.. but so slow, no +/++ icon at all
Hopefully you guys at Asus can solve this problem.
I'm guessing you have a defective device. Try to charge it in the best way you can until the lockdown has ended so you can visit our service center
