    Question [HELP] My S4 charges very slowly, battery or charger problem?

    Hey everyone, so basically my s4 started to charge very slowly recently and I think there could be two possibilities , either problem with the battery or the charger or both.

    1. I think it's the battery because I always charge my battery while calling my girlfriend. And by always, I mean ALWAYS, 90% of the time.

    2. I think it might be the charger or cable because I'm using an iPad charger and i guess that might damage the cable?

    This problem only came up recently all of a sudden. Can someone please help up? What should I do? What's the problem?

    My opinion I would look at the possibility of a battery going bad. Overcharging before the battery is depleted or living on the cord could lead to early failure of the battery. You could use a few different apps available from Google Play that will give you a better idea if its a bad battery by telling you more in depth details health speaking on you battery.

    As for the iPad charger, nah.. I've used Blackberry, Palm and varying OEM's chargers and cords over the years and yes even my daughter uses her old iPhone charger adapter on her Android phone with no obvious signs of damage. Maybe she's been lucky but I doubt it for the amount of time shes been doing it.

    Any quality cable and charger won't cause damage. The phone will only take whatever power it needs.

    You can install battery monitor widget to set up battery monitoring and see what rate you are charging at to see if there is a problem.

    So do you think it could be the battery problem? I've been charging it for like 3 hours from now and if finally charged to 30%. I didn't even touch it.

    Log with battery monitor widget while charging and post screen shot. It could be a charger or cable problem.

    Yes, I've installed it. What information can I get from it and what would show me my battery has a problem?

    Set up battery logging every minute, then let it run for an hour or so, and check on the chart similar to what I posted. My guess is that the charging rate is very slow, but a log could confirm.

    In the app :
    Settings - battery monitoring - monitoring intervals - every minute (accurate but may consume more data)

    Certainly slow charging rate. I would suggest trying another quality charging cable and charger.

    Do you think this could also be caused by battery problems or are you sure that it's the cable and charger problems? I think it can't be the charger's problem since when I use the cable with my powerbank, it's the same situation. So the cable?

    Something else to test is to let it monitor when not charging and see what battery consumption is.

    Your charging rate seems odd.

    Also I would clean the charging contacts. Use a toothbrush and rubbing alcohol.

    It could be the fact that you aren't using the original charger that came with it. The original charger works with Qualcomm quick charge, and when I charge my phone with any other charger, you can definetly see the difference. Hope this helped.

    Nearly impossible to tell if you have a bad battery or charger unless you are able to have a spare of each and swap them out.

    A way to look at it is if you have a 1500 mAH charger - that means it can supply enough power to charge a 1500 mA battery in 1 hour. You need to check the charging rate of the charger and the amp rating of the battery.

    So basically, I went over to a dealer and tried a brand new charger and cable. The data is shown in the attachment. @dpham00, what do you think?

    The s4 comes with a 2 amp charger stock, assuming genuine Samsung . But regardless, the charging rate is going so over the map. If I had to guess, I would think something is wrong with the charging port.


    Have you tried to clean it yet?

    I've cleaned the battery contacts but not the port yet. How do you clean the port ? @@

    Btw, when it was charged using the charger at the locator. The mode was USB charging ( might be because of not plugging it correctly? )

    I think if the plug was plugged in the amp would be higher. Don't you think so ?
