LG G Flex is the first smartphone with a curved battery
Several weeks ago, LG Chem confirmed that it has successfully developed a curved battery, and now we know which smartphone the cell will be outfitted in for the first time. This is, as expected, the newly-announced LG G Flex – the battery was made specifically for company's first curved screen smartphone, minimizing the dead space inside the handset's body by following its curvature. 

LG Chem has applied its patented Stack & Fold technology, which does a great job at minimizing the stress on the battery's components as the cell is being molded to the desired shape. At the same time, the company has managed to maintain the battery's high stability and performance. Even with its unorthodox shape, the curved battery inside the LG G Flex can hold 3500mAh of charge.

Two more innovative battery designs presented by LG Chem earlier this month include the company's Stepped and Cable battery technologies. The former allows for two batteries to be stacked together, thus forming unusual battery shapes that make the most of the space available inside of a handset, while the latter, designed for low electricity usage and minimum heating, allows batteries to be bent, twist, and even tied in a knot.

Nice. Good job utilizing space..
but it should have been a 5"inch or 5.5"inch
6 is too large.. At least for me.

It has not, that's why it has "only" 2800 mAh instead or the 3200 in the Note 3.
Good work for LG managing to put a 3500mAh battery in a curved phone!

PSH, does it have 64 bit with 1 GB of RAM, because otherwise it is not innovation or invention.

A flexible battery isn't innovation to you? Really?

Fact is, A7 has the best per core performance but rivals the Note 3.

SE W300i - a 2006 phone - has a curved battery.
The difference between Li-Ion and Li-Pol is that the last can be molded into different shapes.
My first Li-pol phone was an Alcatel OT 500 something with black and white display back in 2002-3.

The only thing this curved LG phone is good for, is that it can be my permanent toilet paper "wipe and wash".

I was wondering how a curved phone had such a big battery capacity.
