Remember that time when your device lost 50% of battery life during the night because a gazillion services from careless apps kept keeping your device awake and you have no way to disable them?
Or when Facebook kept waking up your phone for no reason and you find no way to fix it other than uninstalling it?
Servicely to the rescue!
First of all make sure you're ROOTED (it won't work otherwise). You'll be able to select which apps will be put to sleep when the display goes off. Just like magic!
You can also disable/enable permanently any service on your device. It's useful if you have services that tend to auto-restart and keep your device awake, or if you have games sending you never-ending notifications.
This app is somewhat powerful so act responsibly when using it. I'm more than happy to help if you contact me
The apk in the Play Store is free with ads, but I've disabled the ads for the apk below. You can still purchase the key from inside the app which helps me keep producing stuff for you, but you don't have to do so.
You can choose between two "sleep" modes. The soft mode I assume it's probably similar to what Greenify does. The hard mode completely disables the apps you've choosed during screen off, and re-enabled during screen on. This mode removes any shortcuts or widgets from those disabled apps, but this is the most secure way to guarantee those apps won't wake up or do something crazy. That said, you'll be fine with the soft mode.
