USB charging yes, but direct charging is fast.

 

That's exactly the same for me too - I was wondering if it was my PC - on Saturday the battery went down to 54 and after 3/4 hour plugged in to my PC it only went up 59, if that.

 

I noticed this as well - it takes several hours now to get this SGS2 charged again (while this was working fine before)

 

I seem to be having the same problem. I switched to ICS yesterday, today the phone has been on charge for nearly 5 hours and has gone from 10% charge to 60%. It's plugged into the wall and not a USB.

 

Wait couple of days, battery should go back to normal, (need couple of full cardges). if that not helps, discardge to minumum, then turn off the phone, cardge to 100%, take out battery and put it back in. If that also not helped, do a hard reset.

 

Yup! same problem here only mine was OK for a few weeks after the ICS update. Now it takes 5 hours on average to charge from the wall mains outlet (not from a usb socket on my PC). Some days it goes back to the usual 2/3 hour charge time. Its getting ridiculous now when the phones been charging for an hour nearly and hasn't even gone up by 1% sometimes.

Phone gets a lot hotter, very hot, more than it used to during charges after only a few minutes of charge time you could fry on egg on the camera lens. I've done a factory reset and its now hardly got any apps on it at all at the moment, and yet its still acting up?
