Why is my Galaxy S4 only charging with certain chargers?

Re: Galaxy S4 only charging with certain chargers

I have been frustrated with charger problems and here is what I found out! Non Samsung 2.1 Amp chargers will not work with the Samsung White cable! Generic cables will charge the S4 at the normal high speed! USB ports are not powerful enough to provide a high speed charge but they will charge the phone if it is off! You know it is charging with high speed when the lightening bolt is on in the battery Icon at the top of the screen.
High speed charging can draw about 500 to 600 milliamps and a USB port will charge with about 150 to 200 milliamps.
There is a signal from the charger to the phone that tells the phone that it is capable of producing the current necessary for high speed charging. This is done with two resistors of a certain value in the charger using the two extra wires in the charging cable. Different cables work with different chargers, look for the lightening bolt! A USB cable extention can cause charging problems too!
I purchase a small USB amp and volt meter on Ebay for about $6 that tells me for sure the USB port is the right voltage and how much current is charging the battery!

When I had a HTC smart phone, every time I had a charge issue, it was fixed by replacing the charging/data cable. Try another cable. If the cable connectors get bent or if it has a contact issue, then you may need a new charge/data cable. I keep one in my car and one in my house.

I recommend getting an OTC (over the counter) that will work with about anything. USB 3.0 charge/data cable (if your phone has USB 3.0) for fast charging. As far as I know, these USB 3.0 have a USB micro male type B connector while the USB 2.0 has a USB micro male type A connector. eBay has some good prices. A charger with a 2.1 amp output, will work with any android phone, iPhone, Ipad, Android tablet that uses an USB connector as these devices are generally downward compatible.

Some chargers do not work with all cables and all chargers do not work with all phones or tablets. Try different combinations and look for the lightning bolt in the battery icon to be sure it is charging at an acceptable rate!

Re: Galaxy S4 only charging with certain chargers

Hello, Im a newbie to this forum but it has helped me a few times when ive done general searches. Ive registered now and I need to ask a question.

My S4 charges normally with its own charger and USB, it charges from my old HTC charger, no problems. Now I've used my old in car charger (used for the HTC) to charge it fine, I brought a solar panel charger for when im fishing over a weekend and the first time the internal battery had been charged by the sun i plugged it into my S4 and it charged it to 100% in about 2 and a half hours. Ive tried to do it again and nothing?? so i thought that the solar battery might npot be charged so in order to test it I plugged my wifes S3 in and bingo it started charging. Ive brought a new in car cradle kit that comes with a small cigarette lighter plug with a USB socket to attach the kits USB cable into. Again it worked one but since hasnt yet does work on my wifes S3?????? because of this I tried my old HTC one in the car which is the old style giant plug in cigarette charger and bingo it charged my phone????. So now im confused, can anyone help with this as Ive spent the last 2 hours looking online at different conflicting problems and solutiions although please bear in mind i'm not electronically minded.

Many Thanks

Luke
