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.
