    just a short reply to Michael Yu1:

    Couple of months ago i bought a S4 charger for my S3.
    at the beginning it was charging my phone in about 2 hours and everything was cool.
    then after a while "as i said i bought it just couple of months ago" the same problem ca,e back again....
    Now i always turn off my phone while charging and it takes about 4-6 hours to fully charge my phone.

    i will post my history with S3 charging problem now, hope anyone still have something that i didn't try it yet or have a new solution for it...

    Good luck and hope your charger won't do the same as mine, by the way i play Clash Of Clans a lot and it's the main reason behind charging my phone a lot during the day.

    For all the Samsung Galaxy S3 users who is having the normal problem which is slow charging....
    here is my history with this problem, hope we all can get a use of it :

    Things that I tried to fix this problem after my original charger start to charger my phone so slow like 12 hrs of charging...
    1- use an IPhone original charger, that doesn't fix the problem.
    2- use a not original charger, that doesn't fix the problem and some of them didn't even charge my phone at all.
    3- i bought a black berry charger, it used to freez my phone and touch screen doesn't work while charging it which was weird and i stopped using it on the same day, so it didn't fix the problem.
    4- i bought a Samsung Galaxy S4 charger "i tested it first at my friend's house using his S4 charger", it was perfect the...
    My new S4 charger was charging my phone in just 2 hours, and if i plugged my charger while playing my game "Clash Of Clans" it keeps charging up, which means i can fully charge my phone while playing but it takes much longer time of course.
    After using the S4 charger for about 2 months, the problem started to come back again (((
    5- some people advised me to hard format my phone, so i did made the hard format from the recover screen, and it didn't fix the problem.... "btw: the hard format code which used from the dial screen, it didn't work on my phone at all"

    NOW I'm really frustrated about how i'm gonna fix this problem.

    PLEASE IF ANYONE HAVE A SOLUTION OR SOMETHING I DIDN'T TRY IT YET, please reply to me and tell me what else i can try......
    Any comment or any idea, will be really highly appreciated.

    Hi to all:
    USB port has charging capacity only 500mAH, and your S3 has a charger which is 2000mAH, so your USB port have 4 times less charging rate. If you are using your mobile during charge how a USB port can charge sufficiently. if wifi is on and usb ported mobile consuming 450mAH/m slightly less than rate of charge from usb how can you charge mobile in an hour...

    Hi everyone,

    I had a very similar problem that is being discussed and followed most of the tips but without success.. (new adapter, battery, charge point etc etc)

    I have now identified the problem and thought I would share..

    1) get a pin
    2) go under a strong light with your phone
    3) clear all debris from the charge socket on the phone
    4) using a pin place it inside the charge point and below what appears to be the connection point ( there is a small chip set looking thing inside the socket)
    5) gently raise it with the pin by applying some pressure so that the connection point raises up slightly
    6) connect and job done it should charge normally.

    I think by using the chargers aggressively it bends the connection point within the socket and this causes the problem

    if you have any questions I am happy to help as it was soooo frustrating and I want to help others before they spend money on fixes that probably wont work
    Thanks for useful advice! I am playing with my phone every evening while on charger and last several months I noticed irregular charge rate. From almost normal up to extremely slow. I tried playing with clearing cashe but this didn't help.

    Then I changed charging cable and I had battery full in 105 min.

    Samsung charger is OK, but if you use the phone while it is on the charger the mechanical stress will finally make your phone or cable micro USB connector bad. Bad contact cause voltage drop and phone cannot get all the current needed for a good charge. So my advice is: start from mechanical and electrical connections as Tom Caddick sad, and if this fails then search other possible cause as battery and charger fault.

    Buy a new charger. Usually it's just charger problem so yeah.

    I'm currently using an S3 but a Note 2 charger and the charger has no problem for already 2 years now. So you should buy a Note 2/3 charger instead. Make sure to check if they fit perfectly to your tab's charging place before buying though.

    Hope this would help.

    Yeah agree with androidgirl3107

    Just buy Galaxy Note 2 travel charger adapter. You can use the cable with the old s3 charger, or with the note 2 charger. It came with the same reading at galaxy charging current lite, a steady 1000mA and it charge fast! It's the cable that matters. Cheers!

    Not a problem with your charger!! only the Cable is faulty, i've tested with 6 different cables & 4 different chargers (3 were 1Amp, 1 of 2Amp). Also used 3 different Test apps.
    So After thorough testing, i was sure that the only fault was in Data Cable itself. now I am using same old original Samsung Charger with another chinese brand phone's USB CABLE and it charges fine!! no need to panic guys, just change the cable until you find the right one

    I had a couple S3's at work that I just could figure out, erratic charging, it seemed like something wrong with the charger or cable, Found out they both have the same problem and it has to do with the cable connecting to the phone.

    After fooling around with both phones I finally found cables that work with each of them, but I can't even swap cables, each phone must have it's unique cable. How stupid. I would never have found this out if I wasn't trying to fix these two S3's. I tried the fix above but it hasn't worked so far, maybe I'll have to use a stronger light to try and see the problem. Other than this fix I thing I'll take each phone to the store and try cables until I find ones that seem to work. From the sounds of it here lots of other people have this same problem but don't know it. If your S3 charges poorly I would try cleaning and then try cables

    But what nonsense, my old S2 takes ever cable and it works fine

    Hi Akshay,

    Firstly you shouldn't try difference charging pins at all with Samsung phones. It works till it works. But if it doesn't its a big problem. You are right in identifying since when it stops working good for you. You need to go to the service center. There'll be 2 things - 1st the phone's charging pin needs to be changed, the cost is Rs. 400,- no other charge. If that also doesn't work then the charging IC is dead. Which will need a replacement. I don't know the cost of that but that's about it.

    You will have the IC replaced only if you have bough the instrument in India, if an international model, Samsung service centre will not change it.

    Hope this helps!

    Beware of low quality chargers, they don't offer a good stabilized output voltage. Low quality cables have a very high ohmic resistance, so the voltage drops when it arrives to the phone. Try both genuine cable and charger and let's see first.

    I use nexus 9 cable with Samsung 2.1 ampere charger.
    Also I turned the current to 2100ma using arter kernel..
    Galaxy S3 I9300 - Slow and inefficent charging problem.-uploadfromtaptalk1431881198905.png
    It charges 0 to 100 in just 50minutes now
    (2100Mah battery)
    [Hide]Theoretically a 2100Mah battery is supposed to charge fully in 1 hour when charges with 2100mA current , but here there is also a increase in voltage (4.3V which is more than the stock 3.8V)
    So
    Power=VxI
    (2100mah×3.8v)÷(2100ma×4.3V)=0.88h=52.8 minutes
    Which actually matches the real value [/hide]
    BTW battery can go insanely hot which may damage it so I use a external cooler to keep it down and I can't use it while it is charging.

    I purchased a Samsung Galaxy S 3 in Nov. 2014. Lately the charger that came with it is charging slower and slower, to the point that if using it while charging it still loses ground, so to speak, in that the % charged goes down not up. Have to either put the phone to sleep or turn off for it to make positive progress in charging. From other posts on this forum, decided to try testing the cable from the charger. I also have a couple of portable battery packs that can be charged and taken to charge the phone when in transit. Took a cable from one of the battery packs and used it and the plug from the supplied cable to see if it would charge faster. Yes, it did. Much faster. For my case, that indicates the cable from the original charger is bad, not the pin(s) on the phone base connector. If I get a new charger & cable, I will report back but for now may just use the cables from the portable battery packs. These battery packs are cylindrical, about 3" long and 3/4" in diameter. They have for some time now charged the phone much faster than the original USB wall charger.
