Battery Indicator occasionally doesn't show charging status

[kmandarin-orange]

Prerequisites

• I have searched open and closed issues for duplicates.

Describe the bug

Intermittently, the battery icon will not change to show charging status when the laptop is plugged in. The computer is charging however, as the "online" output in the screenshot below shows that charging is active and working.

To Reproduce

As of now I haven't found the pattern to reproduce this, but usually this occurs after about +16 hours of uptime. It might be related to suspend since I use that frequently.

Expected behavior

When the power cable is plugged in I expect the indicator to show the charging icon until it hits 100%.

Screenshots or screen recordings

Logs

Unfortunately I couldn't find any of the applicable logs for wingpanel, if anyone does know where to go for that I'll add logs (I'm fairly new to this, so thanks for your patience).

Platform Information

• I'm using the latest released stable version

Additional context

I've also discovered that if I log out and log in again the problem does disappear for a while. Like I mentioned earlier this bug might be related to the suspend feature, since my computer suspends at least once or twice a day, but I haven't taken note of that myself so I can't be sure.

Quick update to show that after 6 months of updates the issue persists on my hardware as well, small kernel and Ubuntu updates haven't changed things. I have mostly noticed it after suspending my laptop overnight, but I've noticed this a little less overall.

Here's terminal output and system info:

I think the problem is with upower not with io.elementary.wingpanel.power

Example:

First step: percentage 95% (not charge icon)

Second step: plug the charger -> percentage 95% (not charge icon)

Thirth step: percentage increase 95% -> 96% -> icon is updated.

I have the same issue.

I have my BIOS setup so that it stops charging when it gets to 80%. In this case I forgot to unplug it so it charged to 100% and then after a few minutes unplugged dropped to 98%. The thing is, my battery is not charging because of the BIOS setting but it is plugged. Apparently elementary does not recognize this state as plugged.
