Is it true that's it's not good to charge your phone when the battery isn't low?

Question

I heard batteries in phones and cameras etc. don't last as long if you charge them too often... is that right?

Answer 1

if its a nickel cadmium battery there is a thing called battery memory. If you charge the battery before it is completely depleted the battery will only run to that point then say its dead. I think that the first few charges are critical after that not so much.
