We're all used to plugging in our mobiles for the long, overnight charge

You are falling to asleep, but you jolt back upright and suddenly remember you have failed to do one thing: plug your phone in to charge.

We all put our charging cables into our phones overnight, don't we?

It helps make sure you wake up with a device ready to go and last throughout the day, or until lunch-time at least.

After all, you aren't having to walk around using your apps.
