I ordered a Samsung Galaxy J3 about a month ago and my Republic Wireless experience is MUCH improved from my old Moto G phone. I was so impressed with the battery life of this phone until 2 days ago. It seems that overnight that battery performance has declined significantly. Even without apps open, suddenly, my phone battery decreases 1% around every 5 minutes even when not in use. I’ve not changed anything. This seems odd to me. Any ideas?
Go to Settings, Battery and tap on Battery Usage. Scroll down to a list of the features that are consuming the battery. You might find the answer there:
Mine is weird because it has had a USB connection to SideSync all day.
