    I just bought a 128gb iPP 9.7 LTE form a guy on swappa.

    I have the identical model, color, etc from best buy.

    The one from best buy weighs 445 grams. The one from swappa weighs 449 grams.

    Small variation, but I can tell the difference.

    iTunes accepted it and I was able to upgrade to 10.01 just fine, but I'm still curious about what would make them have different weights.

    Any ideas?

    I doubt you tell the difference if repeated 20X.

    Do a double-blind test 20X and report back.

    Get your wife or friend to help you.

    I too find it hard to believe that you can notice 4 extra grams in a over 400 gram device.

    I am still puzzled why they do not weight the same. I have weighed both of my 9.7 iPad pros, same model and they were within a gram of each other.

    Difference in variations for the weight of the aluminum or adhesive perhaps.

    Is there a screen protector or things like that?

    Extra adhesive to mount the battery could be it. We are looking at 4 grams or about the weight of 4 paperclips.

    At first, I thought at @Alexrat1996 created this thread. Interesting with the different weights though.

    its probably dirt and grease. Run it through the dish washer and then weigh it again. That'll sort it out.

    I first noticed the weight because there was a really thick glass screen protector on the swappa iPad when I got it. That, of course, made it heavier and made the feel much different in hand. I took the screen protector off and they got within 4 grams of each other and for a while I noticed the went but as the evening wore on, I couldn't tell the difference.

    Still curious about that small difference in weight, but it's a working iPad for a great price so I'm happy.

    You can recognize a 0.9% difference in weight between two objects that each weigh less than 500g? You should be less concerned about this unexpected discrepancy and more concerned about the fact that you may be an android.

    LOL! This is the kind of thing I could say to my tech-illiterate parents, and they would totally believe it!

    Different part suppliers. For example the iPhone 6S has CPU from either Samsung or TSMC. The TSMC chip is much larger and theoretically would weigh a tiny bit more. There have also been different LCD screens for same model iPad (Samsung or Sharp).

    So in your iPads there are probably different parts suppliers for something or other. Perhaps the battery.

    A sheet of paper weighs more than 4 grams. There is absolutely no way I'd ever be able to tell the difference in weight between two iPads if only one had a sheet of paper on top.

    They might have components from different manufacturers
