Recently, my me connect phone app. indicates that the Starter Battery Partly Charged is displayed very soon after I'm parked inside garage. I have a 2019 C63s coupe.
So as per instruction: drove 40 minutes plus at highway speed where the me connect app then indicated Battery Fully Charged. I have done this 3 times over last few weeks. Then after parking and simply opening and closing the door a check of me connect say 1 hour or so later it indicates Starter Battery Partly Charged.
Not sure why this is happening? Made an appt.tomorrow at MB Dealership .
I had my car at the Dealership a few months ago for a rattle. It was there for 10 days so not sure if the Battery was drained and not fully charged when I picked it up.
I purchased new in April 2019, so not sure if the Battery needs to be replaced would it be covered under warrenty.
a Red dot comes on my me connect app. wondering if a notification of the battery issue?
It's normal and nothing to worry about. Technically everything less than 100% is partially charged. These cars don't fully shut down when you park them. They keep the Internet connection and telematics active, so that you can check the status of the car from the Mercedes Me app and do things like remote start/lock/unlock, so that slowly drains the battery like it does in your mobile phone. If the battery goes critical you'll get an alert in your email and on your phone, and even then the battery is far from actually going flat, but it may soon not have enough charge to turn over the engine. I typically get the critical battery warning after the car has been in service for a week, but outside of that it shows partially charged quite frequently unless I do a really long drive. There's a standby mode you can activate in COMAND, which turns off the connectivity features and preserve the battery. You should activate that if you don't plan on driving the car for a while. As an added bonus it will show you how long you can leave the car parked w/o requiring a trickle charger. I use this when going away for at least 2 weeks.

Update. At MB Dealership today regarding Battery issue as noted above.
SA advised a common issue with phone app showing Battery Partly Charged. Nothing to be concerned about but had tech. do an inspection. He confirmed Battery is fine. 1 1/2 hour later on my way.
Weird, right now about 8 hours after leaving Dealership and car parked the app.shows Battery Fully Charged as it always did until recently. But before my prompting a visit to the Dealership today the app. would show Battery Partly Charged almost immediately after parking. Not sure but glad it's ok.
