Battery care doesn't work

At first, i used to schedule in the battery care to fully charge at 7.15 am . Whenever i see the phone in the morning like 6 or 5.30, the phone seems to be fully charged. So this time, i kept the end time as 9.15 and then guess what happened. The phone was fully charged before 6 o'clock. What's the logic in having battery care if it doesn't even work?


  • Scheduled charging will fully charge before your set time but 3h seems to be a bit too much. I've seen that it fully charges 2h before the set time and this is considered normal but I believe this could be a bug. We are aware that it's not perfect and there are plans to redesign this feature but until that happens, we can try and find this bug. I will send you a PM with instructions on how to install a log tool

    My schedule is 23pm-7am. If I look at the phone earlier it will not be fully charged. I have intentionally put it to 7am as my wake up alarm is set to 6.30

  • I don't even know when my phone charges fully. My schedule is from 9:15pm to 9:30am. But when i saw my phone at 2.30am it was fulky charged.

    Not in my case. It works as it is supposed to. Checked yesterday at 5am and it was 86%. Checked half an hour later it was the same. The system was preventing charging. I really don't understand why there is so much inconsistency with user experience. It should work equally for all.

  • Yes. I think many users are facing the same problem. Asus really needs to do something about those bugs.

  • We have received your bug report and I will forward it to our devs so they can see why it bugs with your phone. Thanks!

    Hi, our devs replied after analyzing your log that the cause of this is that your phone was in a different time zone when you set the time. You hadn't connected it to the internet before you set the time so scheduled charging thought it was a different time zone. I replied them to try and find a smarter way of checking the time. You as a user shouldn't have to think about this.

  • What should i do now to make the battery care work?

  • What will be the default timezone used by the Battery Care app in such cases ? Would it be GST ? If so we can set the Start and End time accordingly.

  • This should fix your issue. Go to settings -> apps & notifications -> see all xxx apps -> 3 dot menu in top right corner -> show system -> press power master -> storage & cache -> clear storage

    Now you can set your alarm again and this trick should/could work for anyone who's experiencing that Battery Care doesn't work as intended

  • Thanks. I will try it and will update this thread.

  • Issue is resolved. Thanks Anders_ASUS.
