I personally, manage my wakelocks, it's not necessary if you have caution in installing apps; even then I use Servicely by Francisco Franco; however this one in specific needs root permissions; though there's solutions that don't require such thing, but, unfortunately don't offer features as efficient.

Also check if you had left your phone with mobile data/WiFi and so on, ON or not, at night. In this case, you can either disable or force stop those running apps in the background. Additionally, you can turn on Adaptive Battery and Battery Saver.
