I haven't done anything that I know of to my phone. Sorry, Galaxy S5.

Welcome to Android Central! Does this happen all of the time now, or intermittently? Does the battery charge up normally?

It would help to see more information. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
