I realize that. However, I would like to avoid having to turn off my phone for 2 hours to charge it, especially if its in the middle of the day which happens to be when I use my phone the most. (Note: I have done no more than check and reply to about 2 SMS during the charging -- so everything but my mobile network is turned off -- all unnecessary apps, WiFi, GPS, and I keep my brightness at 25% --> phone finally charged after 3.5 hours).
For now turning off the phone to get a faster charge may be the best approach, but what I'm trying to find out is if this is something other owners have experienced, or if it is unusual for this phone to take so long to charge.
