hey, you used the phone just as similar as me before the 925, i used galaxy s ace before, now i am using 925. Actually the 925 is suitable for fast good games, i now playing dungeon hunter and asphalt 8 on it, howver the back of the phone near the camera area will getting hotter and hotter each time, but dont worry that is the processor area, after u stop playing it, it will cool down pretty quick. As for hte battery, if continunous playing games, you can laast about up to half day depends on what game, now i am casually using it now, without gaming, i can say it will last up to 2 days, with casual facebook, youtube, or twitter stuff, hope you find this helpful. I recommend this phone, however if possible, i suggest you get the lumia 930, i cant get it because i already bought 925
