Using mechanical system alongside charger to charge battery

[sahajmudbhari]

A new idea by me: if mobile phones had a mechanical system to manually charge the battery alongside using a charger it would be helpful to the users in so many ways. If the battery just died or it was low and there was no electricity then we would manually charge the batteries. We could use a wheel or push buttons or anything else to charge the battery.

And how will this scientifically work? You're saying this will work the same way as to how hydroelectricity is generated?
We already have power banks for the purpose you said.

I think the people in research team can workout something if my idea is practical. Yeah same way hydroelectricity is generated or the way cars charge their battery using the motion of tire. We do have power banks but what if we're not carrying one thinking we'll just charge it in the next stop but the phone battery died in between. So we could mechanically charge to 5 or 10 % and use it for emergency situations.
