No-data cable charges really slow

[AC Question]

Hey, I made power-only cable by that I removed the DATA wires in the cable.
But now my cable charges really slow. I've read now that "Technically USB requires the data lines to request more power from a host device, so a cable missing these connections would, in theory, only let devices charge very slowly. In practice most USB hosts will not enforce such a limit. It is also possible that some phones will refuse to charge without data lines in the cable". Is there anything I can do with my phone to make it charge faster even though the cable is missing the data wires?

None. I can't even see any reason to remove them.

What you said needs clarification. With just the power wires connected the phone restricts charge to about 0.5 Amps. The reason for this is that 0.5 amp is all a usb port can safely supply and the usb data pins are high resistance so the charger sees them as diconnected. Ripping out the wires makes them really disconnected and does the same thing. There is a jumper across the data pins, inside the charger. When you plug in the cable, the phone sees the short and and permits a high charge rate because the phone knows it is not charging off a usb port. Thse charge only cables with no data wires use heavier wire for the charge lines but the jumper on the data lines is right inside the micro usb plug. Those data lines need to be jumped together some place,whether it is inside the charger or inside the cable plug. A lot of cables are pure crap and thin wire charge lines or poor plug quality restrict current even with the data lines connecting the charger jumper to the phone It is not necessary to buy a "charge only" cable to get one with heavy enough charge wires. It can have data lines and heavy charger wires too. I have had good results from the cables from Anker. I hope I explained it clearly enough.

Hey, thanks for the answer. My English is not my mother tongue so it was a bit difficult for me to understand.
Do I have to connect the data+ to data -(short the circuit) in the USB, where it's connected to the charger, or in the micro USB where it's connected to the phone? Or both?

Either. A short (jumper) anywhere on the data lines is the same thing. Once is enough.This will put you where you were but if the charge lines are thin or the plug makes poor contact you will still not get best performance. Unless you have good cable, using a very short cable helps even if it is not the best. Your English is fine.I did not realize it was not your first language. Tell me how it works. Get a decent cable. Unfortunstely there are many poor cables out there. Read reviews and avoid any with complaints about low charge rate. Don't go longer than necessary.

I tried to short the DATA wires in the charger, it didn't work but when I shorted the device's DATA wires it did work.
Thanks a lot!!

Yes. Shortening the data pins on the device side will do the trick. It is the device which decides how much current to allow and it is more complex than that. What you did works for most of the Android devices with Micro USB port. In fact this works for some of the new USB Type-C devices as well.
It gets even more interesting if you have a Qualcomm Quick Charge device. Those will not be able to use the full potential of their charger if data wires are missing. In those cases data wires are used by the device and the charger to "negotiate" charging current AND voltage. Yes ... new chargers van raise the voltage up to 20 volts and will support up to 5 amps current. So if using no data cable with the Qualcomm standard you will only get standard 5V/2.4A charging max as the phone will not be able to tell the charger to increase the charging power.
And to get it even more interesting you now have the USB Power Delivery standard which does not use the data wires but the power wires for voltage/current negotiation. So I am testing different devices with my universal charging cable (no data on micro and Type-C):
LinkOn 2m/6,6ft Multi Charging Cable

It works very well so far but most of the new Samsung phones will charge faster but will not show fast charging.
All the other devices will work just great. And due to the solid wires used in the cable it will charge even multiple devices simultaneously with a decent speed.
