Samsung Galaxy S7 Edge not charging after Android Nougat update [Troubleshooting Guide]

It seems like may Samsung Galaxy S7 Edge owners have encountered charging related issues after the anticipated Android Nougat update. While it’s obvious the problem started after an update, we really can’t tell for sure if it’s a problem with the firmware because more often than not, issues like this have something with system caches, files and data.

In this post, I will tackle the not charging issue with the Galaxy S7 Edge being the subject of our troubleshooting. The best course of our troubleshooting would be to rule out one possibility after another so that we can reach the point where everything is pointing to one possibility and that might lead to the resolution of the problem. So, if you have an S7 Edge, recently updated it and now experiencing charging issues, continue reading below as this post may be able to help you.

Galaxy S7 Edge no longer charges after Nougat update

Problem: Shortly after the phone rebooted after the update, I noticed it wasn’t charging. The screen says the charger is connected but it stayed in 32% even if I left it plugged in for 15 minutes. If I had known the update would ruin this, I never should have downloaded and installed the new firmware. Can you please help me?

Troubleshooting: There are only a couple of things you need to do for this problem and both of them are general troubleshooting procedures for firmware issues. I am certain that one of them will  fix the problem, so here they are…

Solution 1: Wipe cache partition

It’s possible some of the system caches got corrupted or became obsolete after the new firmware was installed and that might be the reason why the phone no longer charges. Deleting all system caches will force the phone to replace them and that may fix the issue. So, here’s how you do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key, Home key, and Power key at the same time.
  3. When the phone powers on, the Android System Recovery screen appears approx. 30 seconds later.
  4. Release all of the keys.
  5. Press the Volume down key to highlight “wipe cache partition.”
  6. Press the Power key to select.
  7. Press the Volume down key to highlight “yes” and press the Power key to select.
  8. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

Once the phone becomes active, charge and the phone and if it doesn’t charge normally, you have to reset it.

Solution 2: Do the Master reset

With the new firmware installed on your phone, some services or system files may no longer be compatible with it. Bringing your phone back to it factory default settings may fix this problem. However, before you do that, make sure backup your files and data as they will be delete and cannot be restored. After the backup, disable the anti-theft or Factory Reset Protection so you won’t be locked out of your device after the reset, here’s how you do it:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.
  9. Tap REMOVE ACCOUNT.

Now follow these steps to reset your S7 Edge…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset”.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

You can also reset your phone from the Settings menu…

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.

  4. Tap Backup and reset.
  5. If desired, tap Back up my data to move the slider to ON or OFF.

Galaxy S7 Edge not charging, turns off with 40% battery

Problem: My Samsung S7 Edge has been on charge for over 30 mins but won’t get past the initial Charging Screen (with the Flash sign). I had noticed that the phone battery would run down and go off even when the battery is at 40% battery life. At the moment, it’s been on charge but wont come on or go past the charge screen. What do I do?

Solution: As you stated, your Galaxy S7 is shutting off even is at 40% there is a possibility that the battery is faulty. In fact, battery life issue is not exclusive in S7 alone but to other Samsung models as well or to all Android phones for that matter. According to some users, even the battery is at 60% a notification will suddenly prompt on the screen saying that the battery is low and after a few seconds the device will shut down without a warning. But since we are not sure what the issue really is, the best thing that we should do is rule out each possibility until we can tell what the problem is, that way, we can formulate a solution that might fix this problem for good. Here are the steps that you need to do:

Step 1: Boot in Safe mode

If you downloaded an app from Play Store prior the issue occurs, that could be the culprit that conflict the system and caused the problem on your device. By restarting in safe mode the third-party apps will be stopped from running in the system. So, while in this mode try connecting the device to its charger and leave it for several minutes to see if the issue occurs. Here’s how to boot in Safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

But after doing so and the issue still unresolved continue to the next method.

Step 2: Clear the System Cache partition of the phone

What we have to do now is to clear the cache partition of the device to make sure that caches are all new next time you will restart the device. As a matter of fact, resetting the cache directory occasionally may also fix issues like: bootloops, freezing, restarting and other software-related issue. To do so, here are the steps:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Step 3: Reset your Galaxy S7 Edge

If wiping the cache partition did not resolve the problem, then your last resort is to master reset the device. Meaning, you will bring back the phone’s system to its factory default by deleting all stored files and data. Although this method is more complicated to previous procedures you performed but most probably, this will fix the issue if you follow it correctly. But take note, before you can do so make sure to backup everything.

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

So, after the reset observe closely if the device will still shuts down without apparent reason. If it is, then obviously it is the battery has the problem and replacing for a new one will fix the issue.
