    Ok, here's what I've done and my results.

    1) Ran battery all the way dead until my 1520 shut itself down. I then let it cool off. N.O.V.A. 3 is a great game, which I love, but it is sure a battery hog!! Still took me almost 3 hours to get it to die.

    2) Put it on the Nokia supplied 1.5A charger. I did not turn any background task off or change any setting on the phone. It took about 1 minute on the charger before the phone booted back up.

    3) I let it go for about an hour before checking anything. For the first time since I've had my 1520 the charger actually got very warm. Not hot or overly warm but what I would expect when it's working at capacity. The nice thing was that the phone was completely cool to the touch.

    4) When I opened my Battery app, the one by Enless Soft LTD, and set the date to one day I saw that it was charging at 40%/hour. This continued until about 85% charged.

    5) Above 85% it dropped down to about 12%/hour. It did get to the 85% in about 2 hours but full charge took 3 hours and 10 minutes. That is not to shabby at all! Again this was from a completely dead battery to full charge with very little usage while charging.

    So, I think my issue had always been that my battery was somewhere around the 80% charged point when I was noticing the lower, 10%-11%, charging rate.

    One more thing that has happened since I did the complete discharge and re-charge is that now when tethered and charging it stays completely charged or charges up to 100%. Before it would continually discharge.

    Just my experience but I hope this helps.

    I'm not sure what to tell you, but I doubt he's the most qualified person to talk to. When I tested, I conducted the tests using 1) A clock and, and 2) The battery percentage meter in Battery saver, not a 3rd party app. Since I can add and I can tell time, I can tell you that it most certainly did charge that slowly.

    That being said, it seemed to be the charger. Subsequent charges with both the stock charger and another 2 amp charger give me a much faster rate, 40%/hr or more.

    So the battery charging faster until about 80% and the issue being with the 3rd party charger....both items I posted proven in the last 2 posts.

    Thanks for confirming guys. (No I don't mean that in a sarcastic or a 'told you so' kind of way)

    So what's the conclusions ? Nokia Lumia 1520 charges slowly as it has a bigger batter?

    no, the conclusion is that it charges just as fast as any other 3000+mah battery out there

    it fast charges up until about 80%, then charges at a slightly slower rate until the battery is full

    there is nothing wrong with the device in general, however there may or may not be something wrong with individual devices

    I experienced a slower rate than that when plugged into my PC. However, the charge was rapid when using the included AC adapter. The battery charge graphs showed a remarkable difference.

    I think there may be more to it than the total amps a charger can support. That doesn't mean the phone will try to draw all that power.

    The more to it is 1) cheapo goods that hardly ever meet their claims, and 2) crappy and/or longer cables with higher voltage drop.

    You can only get so much of a charge out of a usb cable, this has a large battery so it will take a while. Now my 2520 has an 8000 mah battery and the same snapdragon 800 but it will charge to 80% in one hour, BUT it does not use the usb to charge, it has a larger capacity charging cord. Now this is why i laugh when i here people complaining about it not using micro usb to charge, they just dont know that is why they are getting such awesome charge rates.
