Problem #1: New Galaxy S6 drains battery fast

Phone won’t charge as quickly or at all. I already try getting a new cable and still didn’t work and some times when I plug the phone and I know it is charging because  I can see the sign that appears when it’s charging but I left it over night and didn’t charged a bit.

It went from 4 percent to 6 percent and the phone it’s only 4 month old. Please help.

Is there a way I can reset the system and try to make it work? Last time I did a soft booting and started to charge faster. Should I do it again? And I think there are 3 ways to do the reboot please if you can help me I would really appreciate it. Thanks guys. — Isaac

Solution: Hi Isaac. We think your phone may still be charging normally but a lot of background tasks or even malware may be discharging power faster than the charger can put power to the battery. In order to verify if our hunch is correct, try booting your S6 in safe mode while charging, leave it overnight, and observe. To restart your phone in safe mode, follow these steps:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • 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.

Safe mode prevents third party apps from running so if an app is the reason behind, the phone should charge normally. Booting in safe mode won’t identify the problem app so you must do a trial-and-error uninstallation to eliminate.

However, if the problem remains even when in safe mode, the next step you must do is factory reset. This procedure will wipe everything from the phone’s internal storage and restore the firmware to its original version. If the issue is due to an operating system glitch, factory reset will most likely fix it. Here’s how to perform an S6 factory reset:

  • From the Home screen, tap the Apps icon.
  • Find and tap the Settings icon.
  • Under the ‘Personal’ section, find and tap Backup and reset.
  • Tap Factory data reset.
  • Touch Reset device to proceed with the reset.
  • Depending on the security lock you used, enter the PIN or password.
  • Tap Continue.
  • Touch Delete all to confirm your action.

Important additional points:

  • All data deleted after the reset cannot be retrieved.
  • Keep an eye on your apps. Many of them are designed to run in the background most of the time. Shopping, communications, and social networking apps are set to constantly communicate to remote servers to update their data. This behavior, even if normal, can drain your phone’s battery faster. Make sure to check individual app’s sync settings and change them to manual to avoid battery drain issue.
  • Not all apps are created equal. There are many free apps designed to inject malicious software (malware) to a device. Install apps only from trusted developers. For example, if you are fond of installing shopping apps, try to stick to official ones.

Problem #2: Fix for water-damaged Galaxy S6

My phone got wet and i did the rice in a bag trick for 3 days. It worked perfectly after that but the was i forgot to remove the SIM card tray before putting it in the plastic with the rice. I don’t know if it affects my situation right now but the thing is that my phone gets reception and suddenly i loses connection.

Sometimes i get texts sometimes i won’t get it. It’s like a lightbulb that flickers (sorry i don’t know how to explain it) and I’m looking for ways to repair it myself because I’m avoiding to pay money for it being fixed and my carrier said that warranty will be void once the unit encountered water damage. Thanks. Im looking for your response asap. Thanks. — John

Solution: Hi John. Internal water damage can lead to all sorts of problems so it is imperative that you make sure the device is completely dry before turning it on again. Even tiny amount of moisture in hard to get places in the logic board can can problems later on. If you’re looking for instructions on what to do, try using Google to search for other online resources (like iFixit) as our blog does not provide hardware troubleshooting and diagnostic.

Problem #3: Galaxy S6 suddenly stops charging

About 3 weeks ago my Samsung Galaxy S6 shut down when it was fully charged and wouldn’t turn back on. I managed to reboot the phone and it started working as normal again.

Last night I noticed my phone would start charging and then stop. I managed to fully charge it then went to bed. After looking through my phone the next morning i went to charge it again as it was low. However it wouldn’t charge. I thought it might be the charger so I used my other charger and it would not charge with that one either. I rebooted my phone in case that was the issue but it won’t charge . The issue must be with my phone but I don’t know why because I keep it in good condition. Any ideas?

Thanks. — Jessica

Solution: Hi Jessica. Charging problems on an S6 can only be due to either a software glitch, or a hardware malfunction. Software-related causes includes apps and firmware, while hardware involves possible issue on the charging port, defective battery, or other internal component failure.

Your first task is to identify whether the issue is on the software or hardware side. To do that, you must perform the basic software troubleshooting like restarting the phone, booting your S6 in safe mode, doing a factory reset, wiping the cache partition, or even turning on the Low battery dump option via service menu (by dialing *#9900#).

Some of these procedures and how to do them are already mentioned above. If you haven’t tried wiping the cache partition of your S6 before, here are the steps to do it:

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

If the issue persists after completing all the software troubleshooting, the problem must be hardware in nature. Consider having the phone checked by Samsung, or better still have it replaced by them or by your carrier.

Problem #4: Slow charging issue on Galaxy S6

I put my phone to charge overnight as I always do and when I woke up the phone was turned off apparently charging and it said it was 100 percent full. I turned it on confused and I checked my messages and emails, then I noticed that the battery was 91 percent that confused me. Before I went out I put it back on the charger and the phone turned off. I put it out and then I checked the charger then put on the phone then put the charger back on. It said that it was charging and then switched from fast to cable charging. It did not charge on other cables and the charger worked on another phone. When I put the charger it said it was charging (already charged 86 percent) and it needed 33 minutes to finish. The minutes however changed and the phone was not charging. Then I turned of the phone. — Jovana

I got my Samsung Galaxy S6 just under three months ago. I have not had any problems up to this point. I just underwent problems charging. I was using a friends charger to raise my percentage enough to keep it alive. It was at around 3% and I raised it to about 9%. When I got home, it was at 4-5%, so i went to charge it. My charger didn’t work. I fiddled with the charger, the cord, and blew into the phone’s charger port. No change. I tried my brother’s charger only to get the same result. I did some Googling and powered off my phone. Then I put it on safe mode and took it off. No change, and phones dies. I plug the cord into my desktop and it sort of works. It’s enough to stay awake, but the battery has been at 1% for the 30-45 minutes or so I’ve been waiting. I’m probably going to bring it in to the AT&T store tomorrow, but I would still welcome your input. Thank you for your time. — Tanner

Solution: Hi Jovana and Tanner. Your issue may be similar to Isaac’s above. Following our suggestion for him may work in your case as well. There’s a low number of battery malfunction cases for Galaxy S6, so doing the software troubleshooting in this article may fix the issue effectively.

Problem #5: Motherboard replacement for Galaxy S6 after it got dropped into water

Phone went into water after a couple of days it came on but won’t charge. “triangle with thermometer “comes on. Since it was a second one, meaning replacement it is out of the question by T-Mobile. And water damage I decided to take it to a repair shop but now that they have open it they tell me that another battery won’t work either and that they have to put it on a machine to pull out corrosion and humidity.

But my question is how was it possible that it came on? and now they tell me that the battery is not the problem when it booted up and I was able to use it for a couple of minutes? i am suspicious that they are trying to switch the motherboard so they can charge me for it!!!

Is there a way to find out if they have done such thing…..thanks in advance!! — Javier


Solution: Hi Javier. Water damage is one of the surest way to kill any electronics. That’s because there’s there are thousands of potential failures that can happen once moisture or liquid comes in contact with the internal components or the motherboard area. Any of the components can become shorted creating a negative domino effect to the rest of parts. One of the first aid steps after a phone has gotten wet is to take out the battery and never turn it on. We know that removing the battery on your phone is out of the question so leaving it off should have been done right away. You want to avoid a short circuit scenario on a water-damaged phone. Turning on your phone for a couple of minutes after saving it from water might had been the killing blow.

If the service center had checked the phone and found out that there are multiple components no longer working at this time, replacement of the motherboard is often the most practical way out.

Unfortunately, motherboard replacement cannot even guarantee a total fix. The procedure may not only be partially effective, but can also cost a few hundred dollars. Needless to say, you’re better off getting a brand new S6 rather going through repair.

  1. Hi my galaxy s6 dropped in the toilet and i grabbed it so quick!

  3. hey i droped my phone on the toilet and know the home key does not working anymore , any ideas how i could fix it ?

  4. I dropped my phone in water and the phone started working but its starts to shut down and right when it reaches the Verizon symbol it shuts off and this just continues and tried everything

  5. My S6 got wet from a soda spill, for days it would not recharge, because of overheating. I disassembled the phone, with the circuit board exposed, dabbed it with a wet cloth to clean it, blew into the holes of the steel protective cases housing the cpu,etc. then placed the phone in the freezer. After 5 hours, took it out of freezer, saw it was moist with wet residue from the freeze process, let it dethaw, and recharged phone. Phone works great now.
