Where I work I dont get much of a Sprint signal. And they dont have Wifi so my phone gets a phone signal maybe 50 % of the time and it killing my battery. when I check my battery usage it shows Cell Stanby - Time without a signal is usually 50-60% . Killing my battery . At home where I get a signal and have Wifi I can go all day and have battery to spare BUT at work my battery drops so fast I guess due to always looking for a signal. Is there something I can do or a APP that I can use to help control this. Any help much appreciated.
