Samsung Galaxy C7 2017 Battery Draining Overnight Issue


This is not a common issue but sometimes the Samsung Galaxy C7 2017 does experience some battery draining difficulties/issues, but as said before, it is not a very common issue so you may or may not be experiencing this issue. But, as a safety measure, i would recommend following the steps below to maybe prevent facing this issue in the future.

Well, you may experience this issue if you have noticed any of the following happen on your device:

  • Your battery has a big drain when you wake up the next morning
  • Your battery drains super fast

If you have experienced any of this follow through with these steps

1. Check All Installed Third Party Apps:  Make sure to check all installed third party apps as some of these apps may be secretly running in the background, draining you of your precious battery life. Also try turning off the Vibrate Setting for notifications when you are sure it is not needed. Vibration is a big battery draining culprit.

Try running your device in Safe Mode to see if there are improvements in the battery life. Running your device in Safe Mode will disable all third-party apps which will help you figure out if third-party apps are the cause of your battery drains.

To enter Safe Mode, follow these steps:

  • Turn the device off.
  • Press and hold the Power key past the screen with the device name.
  • When ‘SAMSUNG’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see ‘Safe Mode’

To exit Safe Mode, follow these steps:

  • Simply Restart your device and you should be out of Safe Mode

Also, it has been reported that some Galaxy C7 2017 models, may or may not require you to press and hold the Volume Down Key during start up of your phone in the same manner as enabling it to exit Safe Mode.

2. Use S Power Savings: Power Saver reduces your device’s performance and limits vibration, location services and most background data to help improve battery life.

    2. Tap any of the following to to turn “On” or “Off”:
      • Speed limiter
      • Background network usage

3. Check Wallpaper: If you are using a “Live Wallpaper”, i would recommend you remove it immediately as using a “Live Wallpaper” is a massive battery drainer ultimately preventing you from using your phone for as long as a full day.

4.Check SW Update: Regularly checking for software updates, making sure your phone is up to date can also help as battery drain can be fixed simply by having the latest system software update installed on your phone. Follow these simple steps to check for SW Updtates
