Come on, 2300mAH is pretty impressive

1) S600 is 40% more battery effiecient than S4 Pro
2) This phone only 4.7" vs Note 2 of 5.5".... smaller screen comsume lesser power
3) Why Note 2 can have 3100mAH? Bcos it is a big size phone, so Samseng can slot it a bigger flatter battery into the phone without scarifying its thinness. If Note 2 is only 4.7" and can put in 3100mAH without reaching a thickness of 15mm, I tiok.

Understand?

What is an UltraPixel?

A stupid trademarked buzzword for one particular manufacturer's CMOS photo receptors that are slightly larger than the other CMOS photo receptors by the same manufacturer, because calling them "lower resolution" is still apparently un-cool, and it's better to just not challenge the mold that more megapixels=better unless we can come up with stupid buzzwords for "better pixels" to explain it away.

Larger sensors have been around forever, and are ALWAYS better. Cramming more photo receptors onto smaller dies has ALWAYS degraded pixel quality. This is nothing new. This has been the case for as long as digital photography has existed, and any photographer already knows this, and compares sensors accordingly. This is just a way to market fewer pixels to the uneducated best-buy-shopping masses, and is just as meaningless as the "megapixels" metric the blue shirts are pushing.
