WeLoveWP.hk have been running some battery charging tests on the Nokia Lumia 800, which post firmware fix should have a battery that is charging at full capacity, unlike earlier, trying to find the best way to optimally charge the device.
Their results were as follows:
|Computer USB 2.0 port||3.85V; ~110mA|
|Nokia DC-11K Mobile Charging Unit||3.9V; 330mA|
|iPhone Charger||3.88V; 300mA|
|Lumia 800 AC-16 Charger||3.95V; 600mA|
From the test it is clear charging from the USB port is slowest, with only 110 mA being delivered, while generic and iPhone charges will deliver 3 times as much. Using the included and official Nokia Lumia charger will however result in charging 6 times as fast, giving a good reason to keep that puck around.
