Charged it fully b4 I went out last night around 7PM. Took several photos and videos, sent numerous texts, made a few voice calls, moderate browser use, FB, YouTube, and spent about 5 minutes every hour zoning out on my "solar winds" live wallpaper! Battery was at 63% by 3AM! I'm totally fine with these numbers! Battery life on the 1st day (thurs) was awful. Dropped 10% on standby in 20 minutes! Huge improvement IMO. Anyone else noticing improvements?
