The iPhone repair experts at iFixyouri have determined that most of the weight savings in the iPad 2 – a fifth of a pound, is in the LCD and Glass assembly.

Here’s a breakdown weights of the Wifi iPads:

iPad 1 – 712.60g iPad 2 – 600.60g (iPad 2 – 112g lighter)

If we break that down even further, the iPad 1 LCD/Glass is almost half the weight of the original iPad.

iPad 1 front half(LCD & Glass assembly) – 347.90g iPad 1 back half – 364.70g

However, breaking down the iPad 2, we find a much lighter glass assembly accounts for most of the weight loss.  The glass we found out last night is 27% thinner than the original iPad. Eliminating the frame that the glass sits on, using thinner LCD and thinner glass, Apple saved 84.7g. That makes up for 75% of the weight reduction.

Apple was able to shave almost 30 grams off of the rest of the device, and with a slightly bigger battery, that is significant.  But the lightness you feel is mostly the glass weight savings.

Our report on the iPad 2 glass from over a month ago first detailed Apple’s effort to save weight in the LCD/Glass assembly.
