Cell Standby Battery Issue?

[JiR95]

Hi guys, I just got the Note 4 as my first Android device about a month ago and I love it! Previous iPhone user here so I'm very new to this.

Anyway, I haven't had any problems with the phone until now. I had a 100% charge when I went to sleep and only about 6 hours later the battery went down to 50%. I'm not entirely sure what did this since I leave the phone in standby with WI Fi on and all apps closed overnight. Until now it has only lost 2-3% battery.
I took a screenshot of the battery menu in settings and cell standby along with Google play services seem to be at an oddly high percentage, and I don't know what causes that. Any help would be greatly appreciated!

When was the last time you rebooted or turned the phone off/on? Because Google Play Services (Play Store as well) will occasionally get an update behind the scenes which can sometimes cause performance issues until a reboot sets things right again.
