Ifyourphone battery is dead and you are somewhere you cannot charge it, or the power is off, then there is nothing you can do. However, when you see this video, you’ll find out that there is an alternative way of charging your phone battery. You will need one lemon. Maybe you won’t believe it, but it is true.The thing is that lemon juice acts like an electrolyte for 2 metal electrodes which are usually made out of nickel and copper. If your charger’s electrodes are made out of magnesium and copper then you will only need a smaller amount of lemon juice as the voltage will be higher.
