I got the extended battery for this phone the other day, as I found that the device is not even usable without it (I was getting around 3-4 hours before my battery would be at 20%). Overall the battery life seems to be quite a bit better, except if I decide to play even the simplest of word games. The phone gets incredibly hot, and I can expect to lose 10% of my charge in about 20 minutes of playing. What really bothers me, though, is that the phone stays hot and will lose another 7-10% of its charge over the next 30 minutes after I'm done playing the game and the phone is just sitting in my pocket. Pretty much any game does this, and this is with the extended battery. I have GPS turned off, battery saver on, screen brightness to about 10%... Is there anything I could be doing wrong, is my phone defective, or is it that much of a battery drain?
