S5 Not Charging With Original Charger

Problem: My cousin borrowed my charging box, and charged his phone with another device’s cable and it worked. But when I put the original cable back to the box to charge my phone, it says it’s not the original charger set so it won’t charge. What do I do?

Solution: Sometimes a glitch in the phone software causes this issue. Try to restart your phone first and see if this helps.

You should also check your phone charger port if there are any signs of dirt or lint as this usually interferes with the charging process. Clean it if necessary using compressed air or a cotton bud dipped in alcohol. Do the same for the USB ports of the cord you are using. Make sure that the connection between the USB cord and the wall charger is secured and tight before charging your phone again.

If the issue persists then try to wipe the cache partition of your phone as this issue may be caused by corrupt temporary data.

  • 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.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

S5 Slow Charging

Problem: I am having problems charging my phone. so i took it to a tech he “fixed” right there in front of me but not sure what he did to fix it didn’t take him but five minutes and showed me on different chargers that it was charging well a week later i am having the same problems and just wondering if you could help me out. when the phone is off it will sometimes charge but if it does it is very slow. So sometimes it will charge and sometimes it wont.

Solution: Try to isolate your charger first by replacing it with another one. If your phone charges normally with the new charger then the old one you are using may be faulty. Make sure to also use a different USB cord as this is usually the first thing that damaged.

When choosing a new charges as much as possible get the original Samsung charger meant to be used with the S5. This means you will need the 2 amp charger with its accompanying USB charging cord.

Next, check the phone charger port for any signs of dirt or lint. A presence of both will usually interfere with the charging process. If you spot any then clean it using compressed air or a cotton bud dipped in alcohol.

Did you by any chance as the technician who previously fixed this issue what the problem was? If the issue was resolved in five minutes then the phone may just have been rebooted. Try to reboot your phone and see if the issue gets resolved.

If this issue is caused by a glitch in your phone software then you should consider backing up your phone data then doing a factory reset.

  • 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, 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 several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

S5 Not Charging

Problem: My Galaxy s5 does not charge when it’s connected to the original charger. I’ve trying connecting it to other chargers but it still doesn’t charge. When i connect it to any charger, including the original, it just won’t charge. Please help me. Thank you.

Solution: When you try to use a different charger are you also using a different USB cord? In most cases it is the cord that gets damaged first which is why you should also try to use a different one.

Try to check your phone charging port as well for any signs of dirt or lint. If you spot any then clean it using compressed air or a cotton bud dipped in alcohol.

There are also instances when the battery is already faulty which is why you won’t be able to charge your phone. Try replacing your battery with a new one and see if this helps.

If the above troubleshooting steps fail then you should bring your phone to an authorized service center for further checking as this may already be a hardware related problem.

S5 Not Charging With Other Chargers

Problem: My SGS5 WON’T CHARGE WITH OTHER OEM WHITE SAMSUNG CHARGERS, MY SISTER GAVE ME AN OLD CHARGER THAT WENT TO HER SAMSUNG NOTE 3 PHONE SHE HAD A FEW CHARGERS THAT WERE FAIRLY NEW N SHE GAVE ME ALL OF THEM SEEING HOW SHE DIDN’T NEED THEM ANY LONGER, N NONE BUT ONE WORKED ONE PINK ONE THAT WASN’T AN OEM SAMSUNG CHARGER, IT WAS AN EL CHEAPO CHARGER.

PLEASE LET ME KNOW SOMETHING ABOUT THIS BC ITS DRIVING ME CRAZY

Solution: The latest Samsung models have a built-in protection that detects the amount of power that comes in from a charger. This helps protect the phone from damage. If the power falls within a specific range then the phone will charge however if the power falls below or is above this range then either you will get an error message prompting you to use an original Samsung charger or your phone won’t charge at all.

Since most of your other chargers don’t work then it could be the that their power output is not within the acceptable range. Another factor that contributes to the chargers not working is the USB cord attached to them. Try using a USB cord that is known to work with your phone with the other wall chargers and see if it works.

S5 Not Charging Properly

Problem: Hi, I am using Galaxy S5 from the last 8 months. From the last 2 months I have observed my phone is not charging properly most of the time. that is after one hour, it is charging only 20%. Occasionally it is charging fast. Suggest me the solution to resolve this problem.

Solution: The first thing you need to do is to check your phone charger port for any signs of dirt or lint. Do the same with the wall charger and USB cord ports. Clean if necessary using compressed air or a cotton bud dipped in alcohol.

If the issue persists try using a different wall charger and USB cord. you should also try charging your phone through the USB port of a computer and check if the issue also occurs.

This could be also be an issue with your phone software. Try to start your phone in Safe Mode first to check if a third party app is causing this behaviour.

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If the issue does not occur then it’s most likely caused by an app. Find out what app is causing this and uninstall it.

If however the issue still remains then back up your phone data and do a factory reset.

  • 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, 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 several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
