Problem #1: How to fix a Galaxy Note5 with a battery issue: won’t go beyond 77% when charging

Greetings. Since the latest software update I’ve been having issues with my battery status level displayed. When the phone is on and charging wirelessly or via usb the battery level does not go above 77%. Now if I turn the phone off and charge it via usb the battery level will charge to 100% but when I turn my phone back on it displays a level in the 70s. I tried the cache clear out on one of you trouble shooting links and have done a soft and even a full reboot a few times. Im wondering if the issue is the battery.

Solution: For a case like this, there’s always a chance that the issue might lie on the battery. To troubleshoot your problem, follow the steps below:

Calibrate battery and OS

Sometimes, Android may lose track of the actual battery levels. To recalibrate the operating system so that it gets accurate battery level readings, do the following:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Observe in safe mode

One of the causes that we should look into is the possibility that a bad third party app may be causing the battery to malfunction. What you need to do is to let your phone run on safe mode for a few days to notice if there’s any difference.

To boot your device to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  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.
  8. Observe the phone while it’s on safe mode for at least 48 hours.

If the battery appears to work properly on safe mode but not on normal mode, that means a third party app is causing it. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note5 is still problematic, repeat steps 1-4.

Factory reset

Wiping your phone’s software information and returning all settings to their defaults is an important troubleshooting in this situation. Make sure to back your phone’s data up first before doing the reset.

To factory reset your Note5:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green 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.
  10. Let the phone run for 24 hours without adding any apps.

Replace the battery

Should nothing change even after doing a factory reset, you can assume that your phone must have a battery issue. Make sure that you get an official Samsung battery replacement to fix the problem.

Problem #2: Galaxy Note5 keeps getting a black screen with a white X at the bottom

I need urgent help please! i am having annoying issue with my Note5 at&t, whenever i connect charger to my phone it opens gear VR service showing a complete black screen with a sign “x” at bottom left or right side of the screen, then i have to restart it by pressing volume and power button simultaneously, i’ve tried around 6 to 7 charger but some problem exists, and if i charge my device after shutting down my phone colour bit changes and stop charging after 5 seconds, i am fed up of this now i have not used my phone from quite long time, please help me to solve this issue, i’ve searched it on google but never get any satisfying solution, please get this issue resolved.

Solution: This issue is either due to a broken charging port or bad software. Make sure that you factory reset your Note5 (steps provided above) to see if a software bug or misconfiguration is causing the problem. If the problem returns after wiping the device with a factory reset, then bad hardware must be to blame. We’ve observed this issue occuring on devices with broken charging ports so make sure to let Samsung check the port so they can repair it.

Problem #3: Galaxy Note5 screen bleeding purple after accidental drop

My Samsung Galaxy Note5 (only 6 months since purchase) fell from the counter to the floor when the charge cord was snagged. It fell about 4 feet. No visible damage to the phone and it was working just fine for almost a week, then the screen started bleeding purple and then went black. It was still functioning properly while “dripping” purple for about a day. The phone will still charge, but screen is completely black. What can/should I do?

Solution: This is clearly a hardware issue. The “bleeding” that you see is an indicator that the phone’s LCD or monitor has been damaged. There’s no software solution for that. Bring your device to Samsung so they can replace the screen assembly.
