Not very long - I went to move it this morning, and it had enough power to unlock but then nothing! MG assist now called

Following an overnight home charge, the app is reporting its at 12.6v which I think is where it should be when not charging. Still no idea why it died! Thanks to everyone for relies.

Thanks. So the battery is working. Just an odd drain on it then! Worth flagging to dealer as it's still in warranty?

Managed to get it charging after a couple of goes. It would lock while charging and cut out. It now says 12v is at 14.4v

Oddly, no low battery warning

There were lots of systems off, but after about 10 mins of driving they all came back. Just got home and plugged into charge at it turned off and won't start again.

Thanks - is it safe to drive? I'll need to jump it again to get home now. And then report to MG as I'd expect it last longer than 9 months?

Hi all. Just drove the mg4 25 reg. A couple of hours later, nothing works. I tried jumping the 12v battery and it started again but as it's less than 12 months old I was surprised thr 12v battery would die so quickly. Does plugging in and charging help to recharge the 12v battery as well?
