iPad 2 Tear down
iFixit done up a very nice summary video on the iPad 2 teardown. The LCD Screen is much thinner, but battery remains very similar.
Based on the video:
iPad 1 LCD Screen – 3.2mm glass
iPad 2 LCD Screen – 2.4 glass
Quite a bit of reduction, but reports are saying that a thinner screen might lead to be more fragile and break easier… Is this what Apple is losing in order for lighter and more comfortable feel? In my point of view, lighter is more important than stronger glass, as we hold the iPad every single day, but we don’t drop it everyday right? Of course who wish to drop their iPad, but maybe it don’t really make a difference if you drop a stronger screen iPad 1 or the weaker iPad 2 screen? Who knows…
iPad 2 Battery
iPad 2 battery only have a increase of 0.2 watt-hour battery, so the battery improvement are all hardware and software optimizing. Results from Engadget shows that iPad 2 battery last almost 1 hour more than original iPad.
iPad 2 RAM
Yes, it is confirmed. iPad 2 have 512MB of RAM which is the same with iPhone 4. This is necessary for smooth multi-tasking.
