Another Update!: Charged my new 64gb black phone overnight to 100%. It is still stock--have not restored from my backup of my 32gb 4S. Pulled off charger at 4:30 this morning and as of 7:00 it is still showing 100%!. Have checked weather and sent 1 text. WIFI ON, Cellular data ON, bluetooth ON, location services ON (but no apps installed), vibrate off (except silent mode), brightness 50% with auto dim on. Now THIS is like the battery life I was getting on my 4, where it doesn't feel like simple standby is depleting the battery quickly. I'll probably run this battery down to 1-5% (may take a couple days!) before restoring. But I gotta say, now it doesn't feel like the phone/battery's fault. Perhaps a rogue app from my 4 was depleting my 4S or I had a bad battery. If I restore and it goes to $#!T I'll know. More later, but for now, bueno!!
