Try using smart actions. I turn off background data from midnight to seven AM, reduce screen brightness down to half at night, wifi is auto on when I'm at home and work which cuts down on data use, and a few other things. Smart actions should help you squeak out that last little bit of up time for your battery. I'm happy to see the battery training worked for you. Once you are getting good up time you can leave these phone on to charge. My phone is my home phone as well so it's on 24/7 literally. If I turn my phone off its only long enough to restart it.
