How to Solve Samsung Galaxy S4 Charging Problem?

Samsung Galaxy S4 charging problem is known to be the most common one, and this is mainly because of the fact that a little bit of physical damage or water damage to the charging connector pin is enough to trouble with your phone’s charging connector. However there could also be other reasons of this problem like faulty charger or phone’s battery.

Problems

  • Not charging.
  • S4 heats up during charging.
  • No response when charger is connected.

Reasons of Problems

  • Charger might be faulty.
  • Charging connector / pin might be faulty or is dirty.
  • Charging dock strip is faulty.
  • Phone might be water damaged, hence damaging the charging dock / charging pin.
  • There are also chances that phone’s battery might be faulty.
  • Uneven voltage at different points on charging dock.
  • Any of the components or capacitors might be damaged or short.
  • Power IC could also be faulty, hence forbidding your Samsung Galaxy S4 to get any charge.
  • Battery pins could be rusty or damaged.

Workaround

  • Check with any other good working charger (Preferably Samsung’s original charger).
  • Check with any other good battery.
  • Clean Charging connector pin and also blow air on it, in order to clear any kind of dust, This could also be the reason of the problem.

Hardware Solution

  • Clean connector with the help of a cleaning solution and check. If that doesn’t work then open S4 and clean all the charging pins from inside and again check.
  • In order to verify there is no water damage, connect charge and check whether S4 heats up or not. If it does, then it means that it is water damage.

  • In order to overcome water damage problem, all you have to do is to:
    • Clean charging dock strip and check.
    • If the problem persists or if the pins are damaged then you need to replace the entire charging dock strip.
  • Now check the voltage of 1st pin (from right) of charging connector with the help of a Multi Meter, if there is a problem then re-solder charging pin.
  • Now check voltage at capacitor, if it is zero then check whether it is short or not, if it is then change the capacitor. If not then:
    • Check the connection between charging pin and Capacitor, if the connection is broken re-solder it or place a jumper.
    • Charge is provided to the Samsung Galaxy S4 board via Capacitor.

  • If nothing works then it must be the problem with Power IC. Gently heat or re-ball Power IC. If it doesn’t work then change the Power IC.

    Its not issue of s4 pins ore hardware. Its totally software. If you notice s4 during charging by any cpu clock checker app. You will see that it mentain on maximum frequency during period which heats up system and also using maximum power which can’t let charge

    • It is really not important that the issue could only be software. There are equal chances of having a software or a hardware problem. Ofcourse Software solution is always recommended, but if that doesn’t solve the problem then you won’t have any other option than to go with hardware of your phone.

  • I was experiencing the common issue where plugging a USB cable was charging intermittently and where the phone could not be used on a computer (device not even recognized as plugged in). There is a consensus that this issue is due to a dirty or faulty contact in the USB port. Some users have reported clearing the problem by cleaning the port or using a vacuum cleaner.

    After attempting to clean the port with no results, I eventually stumble on this page, which seems to the the only one actually suggesting troubleshooting steps for solving USB- and power-related problems (as opposed to whining about Samsung).

    I ended up successfully cleaning the port by removing the charging dock strip and using isopropyl alcohol with a cotton-swab and some kind of very fine interdental brush (?). I cleaned inside the port as best I could (although tricky) and on the dock connector (second picture here).

    It resolved completely the problem and was charging on the first try. It now charges normally (and detected by the phone) and is detected by a computer and transfers data.

    • Good to hear that our guideline is helping others to resolve their Smartphone’s related issues. I hope you and others get more benefits from our Guideline in future as well. Best Regards.
