herry.soewitodon't know when did you buy the phone but its a year old issue started happening soon after Pie update last year and this issue happens only during summer time when environment temperature is high. During charging, when device temperature goes beyond 43°C, the charging starts malfunctioning and the notification light starts toggling as green and red, green and red. This issue happens at different charging % like 63%, 68%, 69%, 71%, 77%.

When I was charging my Zenfone Max Pro M2 (ZB631KL), I get the led blinks at 68%. It blink green and orange. When I checked the battery indicator, it was unstable connected. I thought my charger adaptor was broken. I use other charger, but it's same. So I think, there is problem in update program. It can be happened after I install the update package. Are you have the same problem?
