Ok thanks! I uninstalled the pedometer to see if it will help. It is strange though, I had the same app on my moto X (2013) and I don't think it caused an issue on that phone (if I didn't use the phone much I could get from 6am one day to midday the next, and I haven't yet been able to do that with this one). The poor signal is typical of where I live, I'm lucky if I ever have 1 bar on 3g. In fact, that is the reason I only buy Moto phones because even with that bad signal I can make/receive phone calls. Anyway, I'll give it another few days and see how it goes. Thanks for the help!
