In my old phone (vx8100) it used a Li-ion battery. In my new phone (env2, vx9100) it uses a Li-polymer.....?

Question

is lithium polymer better than lithium ion? if so whats so much better, advantage/disadvantages

Answer 1

The Li-Polymers are a "safer" battery with most of the same advantages of Li-ion.  Li-ion has had some problems when mishandled, overcharged, or shorted the newer polymers reduce those issues.  Here is a great article.
