So I am having an issue with my Nokia Lumia 1520 and its battery. There are some days I unplug it at 100% and within 20-30minutes it has gone down to 80%, typically it is pretty hot during these moments. But most days however, no matter what i do it drains 8%-10% and hour even if I let it sit there. I uninstalled facebook messenger, I don't have whatsapp, and I have limited other background tasks. At one point I even turned off Cortana, and even though the standby time increased, it really didn't make that much of a difference. I am really hoping that this is a hardware defect or it will be fixed with a software update solution. In the mean time did anyone else solve this issue? Hopefully someone can help me. Other than this crazy battery issue, I love this phone. This phone will be a gift from heaven if this battery problem can be solved.
