Hi,

i noticed just today that my phone charges slow even though it has that + sign on the battery when charging.

I restarted my phone and left it charging for 20-30 minutes but it has increased its percentage. I charged it roughly around 22% this afternoon but 30 minutes later, it's just at 30%. Is this because of the AI charging? or something else..

  • Hi delvoux01,

    Good day.
    Have you turned on the AI Charging or Scheduled Charging?
    Do you use Asus original adapter and cable? Do you charge it on standby?
    I would suggest you change another cable for a check.
    Please turn on "Air Plan" mode to charge the device on idle.

    Thank you.
  • Hi,


    I'm still using the same original charger that comes with it. And I charge it on standby.


    I figured it was the AI charging that's making it slow at times. 


    Thanks

    Hi delvoux01,

    I apologize for not replying to you earlier.
    (1.) Scheduled Charging: In order to help to extend the battery lifespan, it stops charging when the battery reaches to 80%. It will then resume charging 2 hours before scheduled time ends.

    (2.) AI charging is based on your previous charging behavior.

    Please kindly refer this FAQ -> https://www.asus.com/support/FAQ/1035846/

    There's a new firmware will be published recently, I would suggest you can wait for the next update.
    I also suggest you can use another cable to confirming.

    Thank you.
  • Hi there,

    I am also experiencing the same problem of slow charging. It all happened when I updated my phone. Usually, it takes an hour and a half to reach full battery since it is fast charging but now, I am charging my phone for almost 4 hours and the battery is roughly by 70%.

    I am using the same charger and cable that comes with the device. Thank you in advance.

    Cheers!
  • Hi All,

    Good day.
    May I know whether your firmware is currently on the latest WW- v16.0615.1903.92?
    If yes. Do you use the Asus original adapter? Could you help me use another cable for a check?

    Thank you.
