Battery notification issue

I plugged in my charger at 10% and didn't pay attention to it for an hour or so and when I checked, it still showed 10%. But as soon as I disconnected the charger, it instantly changed to 98%.

Edit: Now it was stuck at 83% and when I plugged the charger it immediately changed to 44% and started charging!

What is the issue?!

I just keep my old slaptop plugged in as much as possible.

My guess is that the xgce4 software has not read your very new machine correctly.

Inxi reports 75% at this time, not unreasonable, as it is discharging.

Also I am useing a very old Dell but my :$ inxi -FBx --no-host System: Kernel: 5.3.8-3-MANJARO x86_64 bits: 64 compiler: gcc v: 9.2.0 Desktop: Xfce 4.14.1 Distro: Manjaro Linux Machine: Type: Laptop System: Dell product: Latitude E6410 v: 0001 serial: <root required> Mobo: Dell model: 0667CC v: A01 serial: <root required> BIOS: Dell v: A05 date: 08/10/2010 Battery: ID-1: BAT0 charge: 47.4 Wh condition: 47.4/62.2 Wh (76%) model: Sanyo DELL RG04909 status: Full
Has quite a bit more info.
How long does the battery last?

If I'm playing games, it last 2-3 hours at most (I set GPU settings to Performance mode while at it), otherwise it lasts around 4-5 hours.

First off:

Where are these readings coming from? I have been assuming :
$ pacman -Ss xfce4-goodies | grep battery
extra/xfce4-battery-plugin 1.1.3-1 (xfce4-goodies) [installed] A battery monitor plugin for the Xfce panel
The battery plugin xfce4 provides the panel.

This link references you can always recalibrate the battery for better accuracy. . This article may help you out.

From the article:

Most people can get about three to five hours of standard usage out of the 4K model, but anything specialized — like gaming or editing — will cut life down even more.

Yup, these readings are from the xfce4 battery notification panel.

I drained my battery just a few hours ago and will inform how it affects. If this issue was always present, I would have known by now whether it got resolved or not. But this issue isn't always there. So I'll check for a few days and will inform you then.

And btw, my system has 1080p display. The 4K display is in the newer 7000 series models.

Hope you find satisfaction. :wink:

I think draining the battery once completely did the job. Thank you.
