Slight battery drain after installing Nova

[bking1901]

Last night I installed nova launcher, and some other applications to get the pixel 2 look. I charged up to 100% then unplugged and went to sleep, and woke up ~7 hours later to find it at 90%. This isn't a major drain, but it usually would only go down to around 96%. I then have been using it a little bit this morning for about an hour, and it's now down to 82%.

This is clearly faster than usual for me, and my question is if nova or another app I installed can be causing this. These are the apps I installed:
nova launcher
just another widget
pixel 2 icon pack

Here's the breakdown from the battery page in settings:
cell standby 6%
phone idle 3%
screen 3%
android os 2%
android system 1%
2 apps 1% each

Thanks all

You can go into the app settings and you will get a what battery the launcher used since last charge...

I have Nova Prime(stable version) installed on my Moto G5 Plus with Pixel Icon pack (Saurabh Gupta) and Dives icon pack. I use Chronus clock and Weather widget. if I charge my phone to 100% before going to bed it is usually 96 - 98 % when I wake up.
Like Tim1954 said,you can check in Settings > Apps for battery usage of each of these apps you installed .

Also, tap on the battery graph and see the signal bar, just in case you are getting a weak cellular signal.
