Wakelock Detector:An app like Wakelock Detector ( https://forums.androidcentral.com/e...=com.uzumapps.wakelockdetector&token=utkaegUN ) can help you figure out what your device is doing during the night hours, but it can be difficult to interpret the data.
Take a look specifically at your Google Now settings and also the "News & Weather" app (it's there, in your app drawer). I have found that the defaults on this app cause it to download both news and weather data at a very high frequency, thus waking the phone constantly, not to mention using Wi-Fi or cellular radios for data downloads.
Tried again last night. From 100 to 74% in 6hr 40 mins. The following Apps were on: Google, Facebook, Gmail, Outlook, Alarm clock, battery. The little LED light on the phone came on and off sometimes.
Left my phone into airplane mode for the night and the battery dropped 10% in 8 hours.

I read about problems with nlpcollector wakelock. I disabled "remotely locate this device" and "allow remote lock and factory reset" under Android Device Manager. Also re-enabled Location services with battery saving mode. Will try again tonight and report back.That's just bizarre. If true, I wonder what the phone is doing in supposedly "offline" mode.
Facebook is set to "Never"Do you have your Facebook app pulling updates every hour?

I'm going to try BetterBatteryStats beta tomorrow if xda-developers - View Single Post - NlpCollector wakelock. doesn't work.
Auto refresh is turned off in News & Weather. Google Now is turned off. Signed out from Google+. Using Gmail native app for mails. Got Facebook, Facebook Messenger and Whatsapp installed and running tho. But I've turned off all automatic updates in Facebook. Nothing more to turn off in Facebook Messenger and Whatsapp.

Do you have Settings -> Backup & Reset -> Back up my data enabled or disabled?Charged up my N5 to 100% last night and put it into Airplane Mode. Airplane Mode shuts down all Radio including Cell, Wi-Fi and Bluetooth went to bed for 8 hours. Looked at it when I got up today and battery was at 98%. So in previous two nights testing I had 96%battery left after testing the phone on two different nights with Cell and Wi-Fi running. The Wi-Fi and Cell only uses a extra 2% of the battery overnight. BTW, I have a weak Cell tower connection inside the house with only one bar signal but a strong Wi-Fi connection. The ultimate test for people having major battery loss over night is charge up the phone to 100% and power off the phone to see if your battery is holding a charge overnight.
Provide you aren't running some power hungry App, then anyone losing a lot of power much more that 8% which is double what I saw should call Google and see if they can help you or RMA your N5. It could be as simple as a battery that can't hold a charge but it is still a RMA issue.
