Strange battery situation

[chaver4u]

After I installed Catalina 10.15.5 on my MacBookPro 13" early 2015 and I noticed the 'battery health' feature in the Energy Saver preferences. That lasted for a day or 3-4. Then it disappeared.
Also in System Informationower:Battery Information the line 'Health' disappeared.


Worst of all: while my battery is fully charged showing 100% in the menu bar, as soon as I unplug the charger, my Mac shuts down. Just like that.
When I restart after having plugged in my charger, everything works fine.
On top of that, my computer shuts down after 2-3 hours when on the charger. No, there are schedules in Energy Saver preferences.


Strange, very strange....and bloody annoying
What now?

Interesting that you saw Battery Health in the Energy Saver, as a 2015 13" MacBook Pro does not get that feature.

Try doing a SMC reset and see if it helps with your battery.

Thanks, but I can't do this SMC reset because today the battery is completely dead. It's charging at 1% for an hour already. I think I need to have it replaced.
