I'm Having Charging Issues - Are All Micro USB Cables Created Equally?

I bought an OEM Samsung wall charger that charges at 1 Ampere. I started to charge my Zerolemon battery with it yesterday at about 6pm and here it is today and it is only at about 80% charge rate. Something is not right. I contacted the seller and they told me that the charger is from Samsung and it charges at 1 Ampere. It is either the charger is a knock off or my Micro-usb cable that connects into the wall charger is not the right kind.
Are there different variations of micro-usb cables that will work better? Some that allow more current to flow over them than others? My cable says that it is 28awg/2C. I remember when I had a playstation 3 I had problems with syncing the device with my playstation 3 with the USB cables I had bought. After tons of research it was the USB cables that were the issue. They didn't allow enough current to work properly with the PS3. I'm starting to wonder if I'm having the same issue with the Samsung Wall Charger. Is the 28awg wire gauge too thin?

- charger is rated 1amp but usually puts out less depending on the quality and efficiency of it. You won't get the fastest charge with a 1amp psu. Get yourself a cheap 2amp and have plenty of headroom.
- also, if voltage in your wall outlet is low (rare) that would affect psu output.
- yes super thin usb cables can be part of the cause.
- of course, if the cable is meant for PC charging, it will be wired in such a way, to not exceed 450ma (or so) whereas a usb cable or charger that is meant and wired for fast charge, will provide...for me...1150ma (Search/Research my past posts for more detailed info)
- also, most kernels, slow down the charge rate as the batter gets closer to 100% charge.
- a bad battery or custom kernel with bad code, could both affect charging speed.

[Q] What is the maximum mA can the mini handle when charging?

Hi guys,
I've noticed that my galaxy s4 mini 3g comes with a 1000 mA (1A) charger and it charges at a very good speed compared to when I plug it to an ordinairy USB port (500mA only I believe) on the desktop.
It gets warm after a while while charging using the official samsung wall charger (1A)
I plugged it in my battery bank where the output is said to be 1500 mA and it charged up much faster but gets a little more warmer in the back.
I have an ipad charger here rated for 2.1A but I haven't tried it yet..
I want to find the fastest but also a safe way to charge my phone in order for the battery life to become longer before I need to buy a new one. So I want to ask you guys here in the forum what chargers do you use?
A good read that made more familiar with charging via USB:
http://www.extremetech.com/computing/159727-how-to-charge-your-smartphone-and-other-usb-devices-as-quickly-as-possible

For the battery life to remain long you should stick with lower amperages. The 1A charger should do you fine. USB ports are typically 0.5A, unless its a USB3 port which gives more amperage I think.
I've used a Mega 6.3 charger on the S4 mini before (2A).

[Q] Z1c discharging over micro USB with 3rd party chargers

Hi all,
I'm running into a strange issue with my Z1 Compact. I've just bought an Anker 40w 5-port USB charger, and when I connect it to my Z1c with the magnetic cable, it charges fine and everything is OK. However, if I connect it using a standard micro USB cable, it discharges at a rate of around 800ma instead of charging.
It's not just the Anker charger - I had a similar issue with an Arctic 4-port charger I was using previously. When I connect to the stock charger with micro USB, everything is fine and the phone charges normally. I'm running the latest build of SlimKat (it was happening with previous versions as well as on CyanogenMod) with unlocked bootloader.
Is the stock Sony charger different to regular USB chargers in terms of internal connections? I can't figure out why else this would be happening.

Stock charger has 1,5A and when you charge phone and at the same time you use it wont discharge. But if you have charger with max 1A or even less your phone would discharge while havy using

That's the thing though - the Arctic charger is rated for up to 2A per port, whilst the Anker is rated up to 2.4A per port, so it shouldn't be that.
Also, if I'm just using the phone normally whilst not plugged in, I might get a current drain of around 450mA from the battery. But if I plug it into one of these chargers over micro USB, the drain will be around 800mA to 1100mA. So it's not that the phone is using more current than the charger can provide; the charger is apparently actively discharging the phone.
I'm using Battery Monitor Widget Pro to check on all this. When I connect to the 3rd party chargers the mV and mAh flicker and jump about, but are steady over the magnetic cable or over micro USB on the OEM charger. Not sure what this signifies, if anything...

Any reason we can't use a generic or old charger ?

I have a couple of generic chargers I've been using with my note 2 for a couple of years. I realize these will charge slower than the samsung fast charge charger but is there any reason we can't use them or will they impact battery life (I would think they would increase battery life); i supect the answer is that they are fine but maybe battery technology has changed and there is some 'smarts' between charger and battery that would be damaged by these ?

No issue using your old charger except as you mentioned it won't be fast charging. I do not believe that the fast charging will hurt the battery. The fast charge only works for the first portion of the charge then the rate of charge slows to a trickle charge.

U can use any charger but i recommend to use any charger with 2amp output as it charges quick 40% in 30 mins insteas of 50%in 30 mins with original.
Original charger has two modes 9v and 5v it charges with 9v untill 50% and switches to 5v after that.

I think the unit i use is a sanyo 800ma 5 volt. I don't mind the slwo charge as long as it can't harm the battery. This is only used during travel and office; @ home I use the charger that came with the device.

You can definitely use another charger. Like said before it wont charge as fast. The adapter that comes with the phone will charge your phone at 9v instead of the normal 5v. If you use a different usb cable with the charger it will still charge at 9v. If you change the adapter, it will charge at the normal 5v whether you use the another usb cable or the one that came with the phone. The usb cable is just wires. The wall adapter is what determines how fast it will charge...

Question Really slow car charging since A13!!!

Hi all, I'm hoping that someone much smarter here can help me. **My phone is at 50% battery while conducting these tests. I've tried 4 different usb cables and 4 different vehicles and 4 different usb car plugs (1amp, 3amp 2.5amp 30w) my P6P only charges at 800ma but fluctuates wildly from 40ma to 400ma to 250ma to 800ma. I have turned off adaptive battery and the such. no joy. I don't recall this issue with A12. I'd really prefer to not have to factory reset...but......
PS I have no issues with same cables attached to my wall charge station, which charges 5 devices @1.5amp each. My P6P shows a steady 1500ma.

You aren't fast charging unless you have a PPS or PD charger with a Type-C cable. Doesn't matter which DC port or cable you use. Your car's USB ports are not fast.

I'm not talking about fast charging. I just need to get the 1.5amps I was getting before with the same setup as I was getting on A12 This is the charger I just bought hoping it would fix the sub 1amp charge rate I'm getting, Without getting 1 amp rate, my phone looses power while driving and using maps and such apps. This was not an issue with A12

Amps don't matter when you're still stuck at 5V.
It should work though. No point in buying a charger with only USB-A.

I had this issue Android 13 until Sept update even with USBC PD PPS 65W charger, phone was draining using maps. now no.
Also I do not believe that Pixel phone supports QC for quick charge so you might be lucky to get 1amp charging from USB A
