Problem #1: Solutions to Galaxy S6 slow charging issue | Battery drain issue on Galaxy S6

My Samsung S6 is about a year old now, so maybe I just need a new battery…but thought I’d check with you first.

I never charge my phone overnight for fear of overcharging the battery, but lately, my phone has been losing lots of battery for what didn’t take up this amount of battery before: 40% of battery for listening to music on the way to work in the morning (20 min commute), 10% for receiving incoming texts, etc. I always use my original charger unless I am at work, and then I will use a power cord and charge my phone with my computer. After I started doing that, sometimes my phone would charge slowly with my original charger, but after unplugging it once or twice, it would fast charge again.

Today, I woke up and my phone was at 20% battery, and then I plugged it in…and it kept losing battery. Finally, I plugged it in and it seemed to be steady at 11%. And I had to leave, so I left – and when I came home it was dead! Even being plugged in for 4 hours!

I took it off of its original charger and plugged it into my computer instead, but it is charging very slowly (it is at 9% after almost an hour). What is wrong with my phone? Will buying an extended battery help at all? — Stephanie

Solution: Hi Stephanie. Battery performance steadily degrades after some time. The rate of loss of performance can vary per user. The more you use the device (and charges it) day in and day out, the faster this rate is. Loss of performance can usually be seen several months after unboxing the device so if you’re Galaxy S6 has been with you for over a year now, the problem must lie on the battery. To find out, you must do some basic software troubleshooting first. If nothing will change after doing these troubleshooting steps, then you can assume hardware is the issue.

Refresh the system cache of your Galaxy S6

The first thing that you want to do is wipe the cache partition. This will ensure that your phone’s system cache is new and not corrupted. Here’s how:

  • 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.

Restart the S6 to safe mode before charging

Another software trick that you can try is to turn off the phone and restart it in safe mode. This will force the phone to run pre-installed apps only, preventing third party apps and their associated services from loading. If charging returns back to normal while in this mode, that’s a clear indicator that one or a few of the third party apps is to blame. To restart your S6 to 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.

Turn off the phone or ensure that only a minimum of apps are running

Signs of battery drain issue can sometimes show in many different forms and slow charging is one of them. It is not necessarily a battery problem but more of a situation wherein the phone is draining power faster than a charger can add to the remaining level. Most of the time, it’s due to the fact that there’s a lot of apps and services running at the same time while charging. This can be remedied by turning off the phone while charging but obviously, that means being unable to use your phone for at least an hour. If you want to use your phone while charging, you must ensure that you lower the number of running apps to the lowest as possible. Apps for social media, email, communication, gaming, and online shopping are some of the common categories that can continuously run in the background or actively while charging. Make sure that you turn them off, leaving only critical system apps.

Follow the steps below on how to do it:

  • Enable Developer Options (if you haven’t yet) by going under Settings>About Phone or About device>Software Info>Build number. Once you find Build number, tap it seven time to unlock a new menu. After the seventh tap, you will then a notification that Developer Options is unlocked.
  • Press the Back button and find Developer options. Tap it.
  • Tap Running services.

Keep in mind that Google hide Running services option for a reason and average Android users don’t typically need to access them as well. But for the sake of troubleshooting and information, we want you to do it so you’ll see what apps and services run in the background. Make sure that you tap on the STOP button for apps that shouldn’t be running while you’re not using them. Remember, some system services may appear unfamiliar to you; make sure you that you only stop an app that you know. Stopping a critical service may cause system instability so be wary when stopping something.

Install available system and app updates

Always keep your system and apps up-to-date by installing whenever there available updates out there. New updates may bring a fix for known issues including battery drain.

Do a master reset

Finally, if all else fails, don’t hesitate to wipe the phone and restore all software settings to default. For reference, follow these steps:

  • Create a back up of your important files and contacts.
  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • 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.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Should nothing change after doing all these steps above, find a way to have the hardware checked or replaced.

Problem #2: Galaxy S6 won’t boot normally

Hello, my name is Jacob and my fiancée is experiencing an issue with her phone and I was told to email you regarding the issue. She didn’t drop it or get it wet and randomly her phone started doing a boot loop. Her screen, when charging has the battery with lightning bolt icon duplicated left and right on her screen as if the screen is damaged. However there is no visible screen damage.  Her phone under a regular boot starts to turn on showing the Samsung logo with the black background, but then it shuts off. When holding the power button and the down arrow, even through the normal boot function it won’t boot, and when using the safe mode option it makes the boot loop worse, repeating the boot option infinitely without anyone pressing the power button. It is really strange. 

Since the phone won’t turn on, I don’t know what version of the Android OS it has or the exact model number, however it is the most recent OS to my knowledge and is a 32gb Samsung Galaxy S6 Edge Plus. We are trying anything and everything to not do a factory reset because we have a lot of pictures we didn’t get a chance to backup.

Even if there is no way to get the phone to work again is there any way to get the pictures and other data off of the phone?  If there is anything you can recommend doing that I haven’t already tried that doesn’t involve losing any data it would be much appreciated, and feel free to email back if you need pictures or a video of what the phone is doing.

Thank you very much. — Jacob

Solution: Hi Jacob. In order to access files stored in the device’s internal memory, the phone must boot normally or in safe mode (and sometimes in recovery mode if you use a custom recovery software) first. If the phone refuses to complete the boot sequence and keeps getting stuck in a bootloop, there’s really nothing much that you can do.

Try to boot the phone in recovery mode and do a cache wipe. Should the issue remain, do a factory reset (if you want to see if the device can boot normally). Factory reset will obviously delete everything.

Problem #3: Galaxy S6 stops charging and won’t turn on

My phone recently started not charging when it died completely. It would show the charge symbol then disappear. I kept it plugged in all day and nothing. Then 2 days later boom it starts charging. When I plug the USB into charger it says on pull down screen that it’s connected but not charging again. Then it starts working here and there and the screen goes all green and other colors until late I unplug it then it looks normal.. never had water damage always in case. Is it a firmware problem? It is doing really odd things hope I explained well enough..tried many cables and wall plugs to rule that out. — Mike

Solution: Hi Mike. To know if this is a software problem, try the suggestions we provide for Stephanie above. If not one software troubleshooting will work, send the phone to Samsung or any relevant party for repair or replacement.

Problem #4: Galaxy S6 keeps losing cellular signal


I’ve been having problems with my phone, having fights with my dad and mom even, because they cannot call my phone, can’t be reached and called, but I’m very sure that i have network and my signals are very good in my area, so I’m wondering what was wrong. I’ve searched and asked tons but all they answered me was a reset, but i can’t even do that because everytime i try to reset my network my settings stops! What do i do now? Please help me.


Solution: Hi Zaine. We’re glad to know that our site has helped you. We hope that we can continue serving Android community with our articles.

Now, first of all, we want to be frank with you on your case. We always make it a point that any issue that involves services from a user’s carrier must be referred to them first. This is due to the fact that the problem may be caused by some network-related issues. Even if you think that the issue may be on the phone, it’s good if you can talk to your carrier first so you can rule out possible account- or network-related causes.

Secondly, we’re not sure what you mean by “everytime i try to reset my network my settings stops.” We can’t proceed to the process of isolating an issue if, in the first place, we don’t even understand what you’re saying. That said, the safest thing that you can do right now is factory reset. Because this procedure will restore all your software settings back to their known-working state, it’s a good way to start for you. We assume that you didn’t modify the official software on your phone (by rooting, flashing a custom ROM, or installing other third party software) but if you did, try to look for forums or sites that discuss issues with the particular software you’re running. Our site does not provide troubleshooting and solutions for devices running unofficial software.

Problem #5: Causes of Galaxy S6 charging issues

Hi there. So I’ve just been looking at your troubleshooting page for my Samsung Galaxy S6 not charging. I’ve tried three different chargers on three different kinds of charging outlets. The most that will happen is the battery with a lightening bolt will flash up, but the green line won’t be there or the red light won’t register.

So, it seems like I’m going to have to send my phone in and I was just wondering two things please. Firstly, do you know why this has happened? Secondly, how much do you think it will cost to get it fixed please?

Also just want to say thank you for what you do, I’ve used your website for various different android related reasons and really appreciate all the help I’ve gained from it.

Hope to hear from you soon.

Many thanks. — Chloe

Solution: Hi Chloe. You’re welcome. It’s our pleasure to extend help to some members of our Android community.

The answer to your first question can be a bit tricky due to a number of factors that can potentially cause an Android device to stop charging. The general rule in dealing with the issue though is simple — if software solutions won’t work, then hardware issue must be to blame. Software-related causes are uncommon but majority of them can be effectively fixed by factory reset. Hardware malfunction is must difficult to fix and even identify unless a thorough check is done. In majority of cases though, a damaged charging port is responsible. If you want to know the real reason for the issue so you can prevent it from happening again in the future, you should ask the technician who will examine the phone.

Repair price for a Galaxy S6 usually costs $200 in the least. Repair can cover part/s replacement as well so it may even go beyond $200 depending on the complexity of the procedure and the replaced component.
