Mine goes warm now and then.always has done.pretty randomly. Not blisteringly hot but just a bit warm compared to normal.
As an update to the battery thing.cleared ram this morning and kept data off and Barry wad at 99.about 4 hours later it went down by just 3 percent.that's more like it,BUT used to get about that on GB with data turned on. Plus in the past few minutes it's already gone down by 3 since turning data back on to write this.
