While my battery life on the 4S has not been terrible, one thing I noticed since getting it was as soon as I unplugged the charger, my phone would drop to 98% within the first couple of minutes. Today, my phone has been on standby so far for 1hr and 42min and I have 25min of usage and I am still showing 100% on the battery. This is what the battery life on my 4 was ususally like. Is it possible something could have been pushed to the phones overnight to improve the battery or is it just a fluke? Anybody else noticing anything different. I had not changed any settings in the past few days.
