I have to plug my 3 year old 4S in once a day and it usually still has 40% or so life left when I charge it at night. Best battery life I've ever had on a phone.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
