Poor battery life on Lollipoped SGN3 SM-N900

Hello, I'd like to know the most hassle-free fix for the problem. Thanks.

For a phone that old, the first thing to try would be a new or different battery. If the battery life is still poor, then it would help to see some battery stats. 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).


You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
