AnonD-320774, 03 Nov 2014Wht is the different between Li-Po and Li-ion battery ?
Lithium ion is:
Higher in energy density.
Cheaper to manufacture.
But:
Heavier.
More rigid in shapes and styles.
More internal resistance, for slower discharging, and lower amperages.
Has greater aging, even if not used for 1 year.
More explosive, so requires an IC circuit.

Lithium polymer is:
Lighter.
Moulderble, and flatter shapes.
Less internal resistance for faster discharging and higher amperages, at up to 65C continuously, or 135C in bursts!!!
By comparison, a typical RCR chemistry 18650 can only discharge at up to 5.8 amps.
While an IMR chemistry 18650 at 2000 mAH will discharge at up to 10 amps, though an IMR chemistry 18650 at a puny 1600 mAH can discharge at up to 15C, but for the diminished capacity.
Has less self aging, even if not used.
Less explosive, so no IC circuit required.
But:
Less energy density.
Expensive to manufacture.

        I have been using this for 6 months. Yes there is some bug in music player and camera (while using indoor its noisy). Otherwise it's a good mobile at this price.

          One of the worst Smart phone handset experience I had, I would suggest go for iphone rather than suffering with this mobile. n no. of issue I have dealt with. I don't understand how they manufacture with out proper quality check.

                                  to everyone saying it has a great camera,

                                  please check this link out..

                                  horrible horrible camera really.. so if camera is your concern, dont buy it. I REALLY wonder how gsmarena tests out units and gives good camera reviews to phones that clearly in the camera dept. Hmm.. Don't think i can trust their camera reviews..
