Troubleshooting Galaxy S7 that won’t charge after Nougat update

Problem: I badly need your help guys. I have the Galaxy S7 and it’s been with me for over a year now. I’m not planning to upgrade soon but I have a problem with it. There was an update recently and after that the phone no longer charges. When I plug the phone in, it won’t respond and I only have 8% battery left. I can’t afford not to use this phone as all my emails that are related to my work is  sent through it. So, if you could help me fix the problem, I would surely appreciate that.

Troubleshooting: I think it’s just a minor problem since the phone is still powered on and based on your description, the only problem you mentioned is about charging. You never mentioned about any other signs of hardware or more complex firmware issues. That being said, we will have to troubleshoot your phone based on the problem you mentioned:

Step 1: Perform the soft reset procedure

It’s a simple procedure but very effective in addressing minor firmware and hardware glitches. In Galaxy S7, the soft reset is actually equivalent to the battery pull procedure we often do to phones with removable batteries. You don’t have to pull the battery out of your S7 as it would require you to pop open the case. Instead, I want you to just press and hold the Volume Down and the Power keys together for 10 seconds. Your device will reboot after you did this, then try charging your phone again to see if it charges now that its memory is refreshed.

If the phone is still not charging after this, then try the next step.

Step 2: Reboot your phone in Safe mode and charge it

It’s possible that some third-party elements are preventing your phone from charging normally. So, to rule out this possibility, all you have to do is reboot your phone up in Safe mode to temporarily disable all third-party apps and services and then, try charging  your phone.

This is how you reboot your phone up in Safe mode:

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

If the phone charges fine in this mode, then it’s clear enough that there’s a third-party app or a service that’s preventing the phone from charging. Find it and then get rid of it but I know it’s easier said than done so while the phone charges, let it charge its battery until it’s full. At least now we know the hardware is working fine. Once the battery is fully-charged, I suggest you backup your files and data and then reset your phone because finding the culprit might take up so much of your time and the challenging part is knowing which of those apps and/or services is causing the problem. This is how you reset your phone:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Backup and restore.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back key twice to return to the Settings menu, then tap General Management.
  8. Tap Reset.
  9. Tap Factory data reset.
  10. Tap Reset device.
  11. If you have screen lock turned on, enter your PIN or password.
  12. Tap Continue.
  13. Tap Delete all.

However, if the phone is still not charging even in safe mode, then try the next step.

Step 3: Connect your phone to a computer to see if it charges

We’re still trying to find out if your phone is capable of charging so if your have a computer or a laptop (or even a powerbank), then you should try connecting your phone to it using the original data/charging cable. If your phone charges when connected to any of those devices, then it’s clear enough that the problem is with the charger itself and in this case, buying a new charger would surely fix the problem.

However, if the phone is not charging, then you should try using a different cable if possible. You may also check both ends of the cable you’re using to see they’re corroded or if something is blocking the connectors. You may also try checking the charging port of your phone for debris, dirt or corrosion. If you can see something irregular, try cleaning the port using cotton swabs. A blast of compressed air may also help.

After doing all this and the phone is still not charging, then try the next step.

Step 4: Try using a new charger if possible

I’m not saying you buy a new charger. If you have a different charger that gives out, at least, 2 Amps of current, then that would make your phone respond to it as long as the problem is the charger. It is through this procedure that you would know if there’s a problem with your phone or not or if you need to buy a new charger. Assuming the phone charges with other chargers, then it’s time to buy a new one because obviously the phone is still able to charge but not with its original charger.

Step 5: Turn off your phone and see if it charges

Assuming the phone still won’t charge with other chargers, the next thing you should do is turn it off and plug it in to see if it charges. If it does, the problem is with the firmware or some of the apps you have installed prior to the update. In this case, you should allow your phone to charge ‘til the battery is full and then do the next step.

Step 6: Reboot your phone in Recovery mode and wipe cache partition / reset

Considering the fact that the phone stopped charging after the Nougat update, it’s time to try to wipe the cache partition so that all system caches will be deleted and replaced with new ones. Some of the caches may have been corrupted during the update and that might be the reason why your phone won’t charge anymore. Follow these steps to reboot your phone up in recovery mode and wipe the cache partition:

  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 device logo screen displays, release only the Power key.
  4. 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).
  5. Press the Volume down key several times 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.

After this, try to charge your phone and if the problem remained, you have to backup all your files and data and then reset your phone. I am certain that if the problem is not with the hardware, then a reset will fix it but you will lose all your files and data that’s why you need to make a backup of those files that are important to you. After which, disable the Factory Reset Protection so that you won’t be locked out of your device after the reset.

How to disable Factory Reset Protection on Galaxy S7

  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.
