Turn your screen resolution down. Also check some of your social media apps or apps. Sign out of some of them. Go to settings - look for apps. Check in app data usage. Look for: Restrict back ground data. Turn slider to the right to turn the option off. Look at your list of apps that are using the most resources. Some apps like Facebook, Messenger and even Google Play store and Google Services eat up a lot of your phone resources. Clear the cache in settings for them. I would sign out of social media when you are not using them. If your phone is low end - you will have low ram, memory and data issues. Having lots of pictures, memes, music on the phone causes battery drainage. You won't believe it but they do. I would purchase a medium to high end phone. Just saying...and good luck!
