Zenfone 5z stop charging at around 82~86%

[jeremy_c_sun]

Model Name: Zenfone 5z
Firmware Version: latest system updates. Android 10.
Rooted or not: No
Frequency of Occurrence: Starting from yesterday until now
There was no recent system update in the past month, afaik.
Yesterday when I was charging my phone, the charging suddenly stopped. Then, it went back on and off a few times in the span of a few seconds, for a couple of times, until it fully stopped, at around 86% battery. It never happened before.
I thought something was broken so I switched to another charging cable, then a different charger, then a different charger in another room, and last a portable battery charger. It worked sometimes and most of the time it just ignored the charging cable.
After a full day of testing, I have the following results:
If a charging stop, it won't come back soon.
The lower the charge on the battery, the better the chance that it would start charging.
If the phone starts charging, it will charge all the way to 8x% and then stops.
Question.
Is this a battery care thing? The battery care setting on my phone has nothing but a time setting. And, battery care wasn't even turned on.
Is this a charger issue? should I just take it back to the repair shop, the sixth time in 3 years? Last 5 times I was there, they were mostly about a No Network Connection problem.
Or the battery is just dying?
My warranty has expired. I want to get an idea about the problem before making the decision of sending it to the repair shop or just buy a new one.

Saw this message, no harm to try, and
HOLY COW. It works!!!
Man, you're a lifesaver. You won't know how bad I felt when it went down to 25% this morning and still not charging.
Any guesses what the problem is?


EDIT: and how long this would last? a few days, weeks, months?

Hi jeremy.c.sun & adityapruthi2001

Thank you for your asking. Before you visit the service center, kindly try some at-home troubleshooting tips below:

1. Please do check your "Battery care" Setting; please turn on and turn off again.

2. Please try to clean your port with soft tools (e,g. compressed air can) so that the battery port will not have too many debris or moisture.

3. Settings>System>Reset options>Reset app preferences

4. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check any disturbance from installed 3rd party apps.

>>>Is there any zone heating up while using/idling? How long has the battery been used?
No heat up at all. The battery has been used since day one when 5z first came out, which is about 3 years. I am a heavy user. 24 hours a day never turning the phone off. I have an okay charging habit, rarely charging it over 100% (usually 99%).

Just a note for you. My phone charged to 82% full at the beginning before it stopped charging, 77% yesterday and 60% today. It seems that mine won't last until the weekend.
The problem to bring it to the repair centre is that they'd threaten to erase your phone every single time and sometimes they really do. Hopefully, it is nothing but a dying battery.
