Phone Charging Faster?

[FranBlagru]

So I have a Nokia Lumia 920 with developer preview installed and I noticed that it charges way faster. I started charging my phone and even when I was using it, it got charged really fast.

So... Is this happening to you too?

I'll take this as a good thing, but I'm not sure.
Thanks for reading

Had that impression too, don't know if it's charging faster or is something wrong with the battery calibration

I actually like that it charges faster as I don't have much patience.
