### Description

The battery plugin shows incorrect battery level value - 1-2%, although my battery level is at 80%.

Rebooting the system resets DMS battery level to correct one, but problem will start to appear again after 5-10 minutes.

Here is `upower` output:

```

This issue started to appear recently (1-2 weeks ago).

### Expected Behavior

DMS reports the same battery as upower.

### Steps to Reproduce

I assume this is either a heisenbug or a hardware-specific problem.

### Error Messages/Logs

Let me know if you need any extra logs.

journalctl --user -u dms

### Screenshots/Recordings

Start by tracing the battery plugin's reported value against the supplied `upower --battery` output, then inspect `journalctl --user -u dms` around the 5–10 minute failure window. Done means DMS consistently reports the same battery percentage as upower without requiring a reboot.
