Did Andrew’s phone battery really die?

Rather conveniently, just at Laura’s front door at the end of the date, Andrew, right, exclaims: “Oh b ***** ks, I was going to call a cab but my battery’s died.”

“Oh smooth!” she laughs. But he insists it’s not a line and he is happy to walk. Laura invites him in to call a cab. Was Andrew planning this all along? Police said they analysed his phone – will we find out the answer?
