Lithium Polymer Battery???

The full name is "Lithium-ion polymer battery"

The only difference being the medium (a polymer) used to hold the electrolyte.

Most every LiOn battery is now a poly. They're cheaper to make, and can be made into more interesting shapes. And, they're cheaper to make 🙂

Because the iPhone includes this as do all current batteries with Apple devices.

There is no difference.

The battery included with the iPhone 4 has not changed since the iPhone 4 was released.

"But what about Apple's "do this longer, do that longer"?
There has to be a difference. Did you watch that commercial here on the website?"

what are you saying?

people are saying that they use lithium polymer batteries already
not sure what your response is?

The difference is the battery is MUCH larger in the iP4 vs the 3GS. It's mostly battery inside. Ok, that's not true, but consider the battery rating:

3GS - 1219mah
4 - 1420mah

(google for mah iphone 3gs, mah iphone 4, and you'll find sites where people open up the phones and look at the batteries... it's fun, and educational)

Adding 15% more battery is going to give you, well, 15% more time. Coupled with lower power chips (like the CPU) in the iP4, and you get even more time.

One of my experience may be helpful to those who have iPhone or iPod.

For about a week the battery performance of my iphone4 were dramatically decreased.I found it hard, even without using it, or otherwise using it as soon as possible to get to evening.
I tried to use App BatteryDoctor type, but maybe things have gotten worse.

I did a firmware restore, even considering the iPhone as New, that is, installing everything from scratch without using the backup and nothing to do:
The battery drops of 10% per hour without using it simply in standby.

Last attempt
Reset DFU

Here's the amazing result:
17 hours have passed since last charge and.....drum roll...the iphone is 90% after sailing, recorded the sermon, etc..etc..
After 24 hours 84%.

I'd like to know why, and wherefore the software so it affects battery life.But around the Internet I found nothing of science, but only assumptions that often are not in heaven or on earth.
