I had the same problem - at random intervals the battery would discharge while the bike was turned off. In the end, Stromer installed a new display.
Things to look out for: Does the display get warm when turned off?
Do you leave your battery charging for longer period of times? I was told by Stromer that this could also cause this problem (though I do not understand how that could be the cause - after 3 days of charging the bike was at 100%; I arrived at work at about 70% - and 6 hours later (switched off) it was down to about 20%). I must say I was quite surprized that a charger that expensive does not automatically switch to some form of maintenance charging — this is standard for chargers costing a fraction of what Stromer charges.
