Hey everyone, We just switched to T-Mobile from AT&T, because of their unlimited international plan for $15 per month (to the countries I call). We traded in our iPhone 5s's with AT&T to get the 64gb and 16gb 5s with that Jump plan. I noticed poor battery life at first, but gave it some time as I thought it would work itself out eventually. Fast forward to today..... My 5s dies so quickly. After 1 hour and 33 mins of moderate texting and light web browsing, I am now down to 75% battery life on 7.0.4. I updated to 7.1.1 to see if it would get better or worse, and I'm losing 1% every 1-2 minutes of usage, even worse. I have read that signal strength may have something to do with battery drain. I have 1 bar of LTE at home, but I use mostly wifi and have been able to place calls with no drops. Could this have something to do with this horrible drain? Also, if we were to go back to AT&T, how would we go about doing this with the least cost? Would we have to purchase new devices and sign a new contract? And with TMO, will we have to pay the full purchase price of our phones to get out of this? At the time we moved, the 2 lines we moved were out of contract and upgrade eligible. Will we retain that, or probably not? We have 2 lines on our existing AT&T family plan that we have not moved over yet, could we go back to join them? Sorry for the long post. Any help is appreciated. Thanks.
