5s battery drain due to low signal
My battery was 100% charged when I went to bed and dead this morning as in 0 zero! 60% of battery usage was low signal. I have a connection issue with this phone to ATT network. My other 4 iPhones work fine so it is not the location. I use wifi mainly My phone drains at work also. I have been told that I can turn the phone in for a replacement but I only have 10 days left on warranty. Is that the only solution? Is there any other way to fix this problem?
iPhone 5s, iOS 9.1
