I'm only getting between 10% & 11% per hour recharge rate on my 1520 with the supplied Nokia 1.5A charger. The other thing I've noticed, compared to my 920, is that when using Internet Sharing with my 1520 plugged in and charging, again with the supplied Nokia charger, that it drains faster that it charges. On the 920 it would charge even while using Internet Sharing. I'm going to run it all the way down today and then let it charge all the way back up. I know, from past experience, that sometimes it takes a few cycles of discharging and charging before getting the best battery life and recharge speed.
I am using zapi batter it say my Lumia 520 charges at 40% per hour. But MY BATTER WENT from 10% to 100% in one hour.
Totalt bakwas calculation. As a engineering students i can guess that batter recharging is not constant. When batter is low it recharges slower and as it goes higer it recharges faster. It simple chemical(law of mass action???)
Just. Like at bigining blowing a ballon is hard. But it becomes easier as it inflates.

Actually the opposite is generally true. Usually the battery charges faster from a low powered state and slows down as it approaches 100% to help prevent overcharging.
i have seen just the opposite to happen @ always.
Li batter have capacitor to prevent over charge

Then you are seeing something that is the exact opposite of reality. LiPo batteries typically utilize rapid charging for the first 50-80% when rapid charge tech is in use. Then they charge the remaining bit at a slower rate to prevent overcharging or overheating the cells in the battery.
Talk to any engineer and they'll tell you that in the cases of quick charge kits that any proper unit will charge fast initially and then slow down the charge over time. The really smart units can ramp up and down based on what they detect in terms of temperature and individual cell wear. This is usually referred to as pulse charging.
Not that it really applies here since I don't think Nokia has that tech built in on these devices.
Ok i live chated with a nokia guy. They said they cant comment on a 3rd party site(can some one raise this issu in nokia forum???)
But he also said 15% per hour is impossible.

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
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.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.
