▪ Tips

► If you have an odex ROM, after the debloating you can see trash odex files in system/app.You can delete they

► For hibernating an app (Hibernating means app is disabled until you access it.So you can access disabled app when you want and you can re-hibernate it for battery.) I can suggest Greenify

► Do not use task killers.
