Have it ever eingentlich on the net. I just noticed that.
Yes, if you always use a cable anyway, then you should and should take out the battery. Maybe that's just broken.
Why does my battery only charge up to 72% of the laptop and no more?
This is mostly done by the software of the notebook manufacturer. This should spare the battery.
Remove the power supply and let the notebook run on about 30% in the battery.
Then plug the power supply back in and see if it's 100%.
Have it already driven down to 10% and it was still only 72%.
Well then it may be that the battery already has a defect.
In most cases, the notebook manufacturers have a tool where you can view the battery condition.
But it is also possible, for example, with the tool HWMonitor.
