I have a client who is on their 4th S4 mini as he is unable to make it through the work day without having to swap batteries. He makes 1 to 2 hours of calls and its done. The carrier keeps replacing the phones and batteries and I have updated them to the latest firmware and updates and then shown him how to turn off wifi, bluetooth etc even mobile data but to no avail. Does anyone have any suggestions the than getting an iPhone (He had a bad experience with iPhone 3GS and he won't go back).
