Welcome.

Check your battery stats at the end of the day. If nothing seems to be using abnormal levels of charge, and your signal is good, you may need a new battery.

I second this: I was finding problems with my Note 5. Brought an Anker Battery from Amazon, and all was solved.

Another thing to consider is the Juice Defender app; I know that when I was on the Nexus 4 is was invaluable in keeping my battery alive and also helping me find out what was causing problems app wise.
