I guess electricity doesn't weigh much
May 1, 2017 6:32am CST
I never seem to notice an appreciable difference in weight of my phone whether the battery is full or empty. And is electricity lighter than air or heavier? I think it must be lighter because lightning travels up, not down. But that means my phone should weigh less when the battery is full. Heck of a thing to get stuck in my head on a Monday morning.

Phone will be heavier when battery is full.The charged battery has higher energy which converts into mass to increase its weight, as per the formula.E(energy)=m(mass)*C2(speed of light.squared).If you run at the speed approx to that of light(which i am quite sure you can),then weight of mobile in your possession will be lighter.
