  • Model name: zs600kl

    Firmware version: WW_zs600kl_16.0420.2006.30_3

    Rooted or not: not rooted

    Constantly shows as charging

    Updated Aug 15,2020 to firmware version above

    After latest Asus update phone shows as charging even when not connected to charger. Battery drains rapidly and phone feels warm. When connected to charger phone will not charge. Random restarts also occur.

  • I thought so. I noticed the battery went lower at times. Like I had a sudden drop of battery level. It's not always but happens at times like there's some calibration issue.

    Just attempted to factory reset phone in order to downgrade the firmware with no luck. Thinking may be a short in the charging circuit and just a coincidence with updating the system on the same day. Phone is not recognized when I connect to laptop and phone gives a message that both USB c ports are being used.

    Update: Let the phone sit until the battery drain completely and the phone would not turn on. Waited a few hours and plugged in the charger. After about an hour of having the charger plugged in the led finally turned red and the phone began to charge again. Holding off on any system updates to see if the problem of battery drain and not charging comes back.

  • Hi friends

    I just tested my ROG I, charging and fast charging perform well. Didn't notice any specific battery drain.

    Please clean the debris off the port with compress air can.

    The issue can cause by various reasons, a common reason is the battery port had too many debris, so that the port keep detect debris or moisture. Please try to clean your port with soft tools (e,g. compressed air can) or bring it back to Repair Center for device checking.

    >Battery drain

    1. Update the apps to the latest version to avoid any conflict between the firmware and the apps.

    2. Enter "Safe Mode" and leave a 80%-100% phone in sleep(idle) mode in a night.

    # How to enter and exit "Safe Mode"

    If the battery works well in "Safe Mode", please check on any disturbance from the installed 3rd party Apps.

    3. If the issue remains the same in "Safe Mode", please try "the Factory Reset" 

    Settings>System>Reset options>Factory data reset

    Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.

  • Thanks. Seems to be a coincidence with having the charging issue and the system update at the same time.

    Charged the phone to 100% before going to bed and unplugged it. Woke up this morning and phone was at 94% charged so the issue appears to be gone now. I did clean both USB c ports with air once the battery was completely drained so that could have been it. Haven't updated the system again as of yet though. Will be holding off on the update a couple days to make sure there are no other battery charging/drain issues.

    Just glad I still have my ROG to use. Great phone.

  • Battery drain issue seems very bad with new update. It's not acceptable.

  • Hi CyberPunk2302

    Thank you for your reply. Can you please assist me to test the method 2 (safe mode over night) above? How long has the battery been used? 

    If the battery has been used for years, I suggest you to bring your device to the repair center for battery checking.
