Hey guys. In this post I will tackle some of the power issues Samsung Galaxy S6 Edge Plus owners encountered after the Marshmallow update. It includes issues like the device just turned off and won’t respond if the Power, or any buttons for that matter, is pressed and other charging problems.

Read on to learn more about these problems and how to troubleshoot and fix them. Thorough troubleshooting is necessary to know what the culprit is and how to fix it. There are, however, issues that require you to seek assistance from a technician especially hardware problems so we cannot offer a solution to those.

Q: “I heard a text notification while working and when I finished up the task (5min later) I pulled out my phone and the screen was black. I hit the home button, no response, I hit the power button expecting to see if the battery was dead but nothing came up. I plugged it into the factory fast charger in my office and there is nothing coming on the screen to show that the phone is in fact charging. It’s been on the charger for 10min now and still, nothing brings a response.

A: This problem often leaves the phone active, i.e. you can dial the number and you can hear that it’s actually ringing but the phone still won’t respond. It’s one of those cases wherein the firmware crashed for some reason and the only thing that could bring it back is forced reboot. Just press and hold the Volume Down and Power keys (it’s better to press and hold the Vol Down, then the Power key) together for 10 to 15 seconds. The phone should reboot after that and you can continue using it. However, there’s no telling it when the problem would occur again.

If it happens more often, then you need to reset the phone as some data might have gotten corrupted for some reason. Back up your data, files, etc. and then remove your Google account and disable the screen lock and follow these steps:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Q: “Keeps shutting off, I’ve tried the volume down and power key combination as well as the volume up, lock, and home button one and the phone did not respond to either. Also it is not dead.

A: Try to see if it responds if you put it on charge. If it doesn’t, then repeat the Volume Down and Power keys combination; you don’t just have to press these buttons together but you need to hold them for 10 to 15 seconds. If the problem persists, you better have the phone checked as it may have suffered from liquid damage.

Q: “Phone had had coffee spilt on it but this was months ago and has functioned without any issues for the last 3-4 months. The phone went to 1% battery yesterday it was put on charge with a gen. Lead and charger i have 4 of these and all proven good.

The phone appeared to report a 26% charge on a non fast charger with in 3-4 minutes which I thought odd, subsequently it went flat and now nothing.

No indicator lights no charging indicator will not switch on any button combination tried charging pad and charger and USB and still nothing. Had been using the phone without issue prior to fault it has just died completely.

A: We must assume first that the phone has drained all its battery that’s why it wouldn’t turn on. So, you need to charge it first but as you said it doesn’t. Try pressing and holding both the Volume Down and Power keys together for 10 to 15 seconds. It may not turn the phone on but if it was just a system crash, then it should get the phone out of it. At this point, the device should be able to successfully charge. If it doesn’t still, then you need to have it checked. It must be a hardware issue.

Q: “I have had my Samsung Galaxy S6 edge+ for a couple of months now, and have been experiencing difficulty when trying to charge my phone via USB charge.  When plugged in, sitting still my phone constantly believes the charger is being disconnected and reconnected. I haven’t touched the phone. No matter which angle I sit the charger, it still “disconnects and reconnects” with that blue animation at the bottom of the screen. My Samsung fast charger that came with the phone was the first with the problem, I believed it was broken and went and bought a new third party charger. Same problem. Have bought more and the same problem is occurring. Please help me.

A: I think the problem here is the USB or the utility port of the phone. We just can’t say for sure what the problem is but based on your description, it might be just loose. The worst case scenario here is when the “daughter board” that holds the USB port needs replacement. That said, you need a technician to further assess your device.

Q: “I’m having an issue with my Samsung S6 Edge+ (model:G928F) where it won’t charge, wired, wirelessly or wont be recognised by my computer or odin.

Surely this must be a software issue right? The problem is I cannot get my phone to turn on as it stays at 0% and I cannot get any files onto it to flash anything through my custom recovery (which wouldn’t have been a problem if Samsung had just included a darn microsd slot, but that’s another argument). What do you think could be causing this? Thanks for your time. — Rhys

A: The only thing we can assume at this point since we don’t know exactly what happened to the phone is that its system crashed that’s why it’s not responding no matter what you do. Try to force reboot it might just fix the problem, so try pressing and holding the Volume Down and Power keys together for 10 to 15 seconds. There may not be enough battery to power the phone up but it might get the phone out of it. After that, try connecting the phone to charge again. If it still won’t do it, then you have no choice but to have it checked up.

Q: “The mobile phone had the power 45%. I put it on the table and several minutes later when I wanted to check my Facebook, it was off. I tried many times to press the power just wanting to turn it on but did not working even until now. I am so frustrated. I just bought it very recently which is 7 months ago. I have charged it for about an hour but there is no sign of charging as usual. I have no I idea how to solve the problem. I plan to the buy the new one but my concern is I might had the same problem to the Galaxy S7. So, would you please help me to sort it out. My mobile phone is Samsung Galaxy S6 edge plus with 64 GB. I appreciate your assistance.

A: If you’re sure that the phone has about 45% battery left, then it’s obvious the system crashed, although there’s no way for us to know what caused it. To fix it though, all you need to do is press and hold the Volume Down button first that press and hold the Power key and keep both keys held for 10 to 15 seconds. The phone should reboot.

If the problem keeps on repeating and if it started after the Marshmallow update, some caches may have been corrupted. Since we won’t know which caches are corrupt and which are not, the safest procedure to address it is by clearing all the caches in the system. Follow these steps and don’t worry, it’s safe; none of your files or data will be deleted.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Q: “My phone won’t totally turns on. After the white Samsung logo is displayed, it just stays there and doesn’t totally turns on. It reboots again and again but it just up to the white Samsung, then it reboots again. I tried to troubleshoot it using your guide, but it didn’t fix it. Please help me! My phone is just barely six months old. Thank you!

A: You should have included in your description which guide you followed so we would know what are the troubleshooting procedures you already did.  To try to troubleshoot this problem though, try these:

  • Boot your phone in safe mode to see if the phone boots up successfully with all third-party apps disabled.
  • Try wiping the cache partition as it is possible some caches got corrupted especially if your phone has undergone firmware update recently.
  • If you can’t enter the recovery mode, then it’s time you sent the phone in for repair.

How to boot Galaxy S6 Edge Plus in safe mode

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Q: “When I plug the cable in to charge, the phone keeps beeping and switching back and forth between saying “charging” and “The dock is connected”.  This started a few days ago and would turn the phone off after a few minutes of doing this.  Now it just beeps and switches back and forth.  It also is charging slowly and the battery is draining fast.  Went from 92% to 45% in an hour and all I did was look at Facebook for a collective 10 minutes.  Please help.

A: Try turning the phone off and see if it charges fine with all its components not powered up. If the problem still occurs, then you should try to reset your phone; boot in recovery and wipe all data. Should the problem occur after that, you need to send it for repair. It might have been liquid-damaged.
