Welcome to Android Central! I moved this from the Nougat forum to the S7 edge forum, since battery life questions are better served in the subforum for the device, not for the OS version.
To better evaluate your battery life, it would help to see more 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).
Install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
