I own a Samsung Galaxy Note 3. My battery seems to be acting up on me. Just 15 minutes after it's 100% charged, it will drop down to 80% even when I am not using it. I do not have a spare battery to make a comparison. Is this normal?
Seems like you will need to check through to your task manager to see if you have heavy tasks running in the background. Often, we just forget to quit tasks entirely and properly and these keep running in the background and consume battery life.
If you do not have a task manager, download one from the Play Store. You will find plenty there.
That problem with your battery is normal for old batteries. As you use your phone, the battery becomes weaker and weaker as the cycle count depletes. If your phone’s battery is a bit old then it’s time to replace it if it’s becoming unusable. But if the battery is not that old, maybe you should check the apps running on your phone.
Check the task manager of your device and close apps that you are not using. Also, every time you run an app, always check the task manager after closing the app to make sure the app did close successfully. Because most of the time, when you run an app and you close it later, the app doesn’t actually exits but remains running in the background.
