Old video, but still useful for finding parasitic power draws:

Hey. Have you found out what the problem is yet? I have a 62 plate 1.0 ecoboost petrol. Having the same problem. I've had this problem for about a year but it has got so much worse over the past month or two. Had the AA out a few times and they just say it's a flat battery but when they check the battery it's coming up okay. Today it wont start at all and is showing up 'normal mode' on the dash. I'll have to put jump leads on it to start it. It's currently booked in with ford for Thursday 18th of June to see if they can find out what's wrong.

I've had something similar over several weeks since going back into work after lockdown. What makes my one odd is that is has only happened when my car has been sat at the office for the day and I am ready to leave. At home on the drive over weekends and not being used it is fine but at the office occasionally I have had nothing, had to manually open the door, nothing on screens inside, open the bonnet and connect a jump starter to the battery. As soon as the jump starter is connected I get either the hazards flash or a horn beep and it starts up like nothing was wrong. Leave it overnight on the drive at home and no problems starting in the morning.

I suspect I have a bad connection somewhere either on the battery or an earth point but open to any other suggestions.

I am on holiday for 2 weeks now so will see if it starts up normally when I get home.
