I was slightly disturbed to read that Emirates are switching to digital-only boarding passes. What if your phone dies?

Which got me thinking – your phone is becoming more and more necessary for everyday life, and everyone has battery issues. Yet your phone’s functions can be divided into essential (paying for things, being an actual phone, messages) and non-essential (games, Tik-Tok).

Whether actually having two different batteries and perhaps even operating systems, or whether virtually doing so, I think splitting the two types of function could become necessary.

Very simplistically, when your battery gets down to 30%, games and so on cannot be run, and only essentials will. It won’t be told to you like that – you will be told that your gaming battery is empty.

The other option could be two phones, an essential phone, and a game/social/camera device. They could even be joined together, two different sides of the one device, with screens front and back.
