My zenfone 5z fast charging not working since a month. It initially shows fast charging symbol. But after a minutes, it shows slow charging.. pls help


  • This is a software issue I m also facing the same problem they will always say to reset the phone for any problem

  • Hi, we suggest you to please visit the nearest ASUS service center for better assistance. Locate here : https://www.asus.com/in/support/Service-Center/India

  • Try to use another cable, or try cleaning charging port with small brush.

  • This is not about the cable, this is in software. Actually, the phone stops charging even when fast charging after 2 mins. This happens once in 2 days. Also, the fast charging ++ symbol with lightning , changes to no symbol at all exept the lightning describing slow charging, infact, when sometimes charging the charging itself goes on and off several times, and yeah, i dont have 5z as my primary device right now so i pretty much reset it every now and then. Pls resolve this issue.

  • I never saw this problem on my 5z since 2.5 years now so i am sure it is not software problem but it is hardware for sure i think some dust particles may have been occupied inside charging port or cable try to clean both by blowing some air and see if you see any diffrence of not than you have to visit nearedt service centre as early as possible before it gets totally damaged

    Note:- Also check by changing your charging cable/ adaptor if that helps
