Fix Samsung Galaxy S4 that charges slowly when turned on & other charging related issues

When it comes to charging issues, there are several factors to consider; damaged charging unit, defective cable and busted battery. There's also one thing that most of us overlook–firmware problem. I want to tackle these things in this post as well as address the problems from our readers that I included.

Galaxy S4 charges slowly when turned on, stopped charging
Problem: Recently my phone had been having charging issues, it would take much longer than usual to charge, but I discovered that if the phone was turned off and charging it would charge a lot quicker. So this morning I went to turn off my phone to charge it and it wouldn't charge and it wouldn't turn on again. When I went to charge my phone it was on 60% already so my battery wasn't drained. I however tried to charge my phone anyway but the phone just got really hot, I was thinking this could be a problem with the battery in my phone as I was previously experiencing problems with it charging normally but I wanted to get a specialist's advice. Thanks.

Troubleshooting: The current issue is that the phone won't charge and won't turn on, although it still has about 60% battery left. Frankly, it's difficult to explain why this is happening or what caused this problem simply because we cannot get to inspect the phone physically. The best thing to do is troubleshoot it and based on the description of our reader, these are the things I would do...

Step 1: Soft reset the phone. This procedure is just like a reboot but with a twist; it will drain electricity stored in some components thus, refreshing the phone's memory. All you need to do is remove the battery and then press and hold the Power key for a minute. Place the battery back in and attempt to turn the phone. It is very effective for minor hardware and firmware glitches but it's purpose in this troubleshooting is to bring the phone back to life.

Step 2: Plug the charger in and observe. If the first step failed, proceed to plugging the charger in to see if the phone displays the usual charging signs especially the LED indicator. It is in this step that you will have an idea if the phone still charges. If the indicator doesn't light up and the phone heats up, then unplug the charger immediately and try the next step. However, if the phone charges fine, there's a chance that you can turn it on right there and then.

Step 3: Connect the phone to a computer or a laptop. Try to see if the phone will charge with the computer. This will give you an idea if the charger is the one causing the heat up or not. If the phone charges, then it's time you bought a new charger.

Step 4: Verify the cable is still good. If the phone didn't charge using the original power adapter or even with a computer, then check the cable as it may have a break or something. A physical inspection from end to end is enough. After this step and the phone still won't turn on, let the tech check the device.

Assuming you have successfully brought the phone back to life but still charges very slowly when turned on, try to isolate the problem immediately by booting the phone in safe mode.

Turn the device off completely.
Press and hold the Power button.
Once the Samsung Galaxy S4 logo appears on the screen, release the Power button.
As soon as you release the Power button, press and hold the Volume Down key.
Continue holding the Volume Down key until the phone has completed the reboot process.
If you can read 'Safe Mode' at the bottom left corner of the screen, release the Volume Down key. Otherwise, repeat the process until you can boot the phone to Safe Mode.
If the phone charges at a normal pace in safe mode, it means some of the downloaded apps are causing the problem. You may try to boot to normal mode and check the apps that use more battery and uninstall them. This is one way of addressing the problem, the other way is to perform a master reset to completely get rid of the culprits. The procedure is also necessary if the phone still charges slowly in safe mode.

Switch your phone off.
Hold down the Power, Volume Up and Home buttons at the same time for about 10 seconds. Release them when the Android logo appears on the screen. This will bring up the unlock/reset menu.
To navigate through this menu, use the volume up/down buttons to scroll up and down and the power button to confirm selections.
Scroll down and select Wipe Data/Factory Reset.
Scroll down and select Yes – Delete All User Data.
When prompted, scroll to and select Reboot System Now. The phone will then reboot to its factory settings.
Galaxy S4 randomly stops charging when plugged in
Problem: I am using my S4 from last 6 months, now its start giving problem while charging the device. When I plug in the charger, it continuously connect and disconnect (even I doesn't move my phone). I checked solutions but almost all of them have this issue while charging from computer/ laptop. I am having issue while charging from device charger. I am wondering if it is due to phone port or the charger or some software issue. Please, if you can provide any solution to this. Thank you so much.

Troubleshooting: Proper troubleshooting is key to knowing what the problem really is. You've already tried charging the phone using the original charger and through a computer and got the same results. The next thing to do is use a different cable. If it's still the same, then it's more like the USB port in your phone that has an issue. However, to verify it's not a firmware issue, try booting your in safe mode and plug it in to charge. Or you may turn off your phone and observe if the same thing happens.

We cannot actually provide a solution to hardware related issues because that's the work of a technician that can physically check your phone. All we can do is guide you to troubleshoot your problem so you will know what to do next. So, if the charging process cuts off randomly in safe mode or even if the phone is off, then send it in for repair.

Galaxy S4 can't boot up with a new battery
Problem: My phone turned itself off and now wont charge or turn on. I took it to the T-Mobile shop where they installed a new battery but then it would only show the logo and nothing else would happen.

Troubleshooting: It's probably just a glitch. If I were you, I would do the soft reset first; remove the battery, press and hold the power key for a minute, place it back it and turn the phone on. If it couldn't boot up successfully, then proceed with the wiping of the cache partition via recovery mode.

Turn off the device.
Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key
When the phone vibrates, let go of 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. The phone will automatically restart after the cache is wiped.
Galaxy S4 drains battery fast
Problem: The charge on my Galaxy S4 charges to 100 percent and then down to 71 percent in 2 hours. I purchased a new battery 2 weeks ago. Now it's 63 percent in 3 1/2 hours. I have the phone set with location WiFi rotate screen and power saving mode. What can I do to keep the battery from draining so fast?

Troubleshooting: For battery draining issues that cannot be explained, it is always recommended to perform a master reset immediately to know if it's a hardware issue or just a temporary problem with the firmware. I understand it's very inconvenient to backup everything but I think it's more inconvenient if you will run out of battery while traveling.

Galaxy S4 won't turn on and charge
Problem: I tried a few of the methods to turn on the S4 but still cant turn it on. It appears the welcome notes" Samsung Galaxy GT-xxx" for one second and turn off again. Also, when I charge the battery, it appears the "charging" icon with 0% of battery for one second and turn off again as well. So what can I do to turn it on and keep the data inside?

Troubleshooting: Try to pull the battery out and place it back in. If the phone turns on immediately without press the Power key, then it means the button is stuck. In case there's not enough battery to power the phone up, try to use a different one (with charge, of course) just to find out if it has something to do with the Power key. Also, if the phone vibrates after it turns off, then it confirms our suspicion.

Pressing the Power key repeatedly multiple times will fix the problem. If not, then it might have been damaged and needs to be replaced. You need a technician to do that.
