Why do only official HTC USB cables give full power charging?

I've read that some 3rd party cables/chargers only appear as DC due to not having shorted data wires but that doesn't explain what I'm experiencing.
I have an official HTC mains plug and car socket plug and when I use the included USB cable I get full power charging of upto about 800ma with phone on. However, with both, if I use 3rd party cables it still shows as AC but I barely get 3rd of that, say up to about 300 max.
What would be causing this and any tips on a reliable source of official cables in the UK so I can be sure of getting full power when using other chargers etc?

Are you sure the cables are shorted?

No. But the HTC ones can't be either as they are also data cables yet they still give full power unlike the 3rd party cables, - even though they are plugged into the same plug. It doesn't make any logical sense.

The official charger unit from HTC have an Hardware different. To charge with full power you need an original one!
There are a few other Provider they do the same. For example Samsung:
mobi-test.de/allgemein/aus-samsungs-trickkiste-nur-original-ladegerate-liefern-volle-leistung/

This is an easy answer. They want you to buy their cable. It's the exact same reason that laptop companies might design a proprietary shaped plug. If it breaks, they want you to buy from them to increase their profit margin.
****ty, but a fact of life.

1) there is NO difference in cabling. You can use any cable with MicroUSB, it makes no difference.
2) the official charger has the data pins shorted, but so do other chargers - for example my Nokia charger (rated up to 5V/1200mA) charges the phone exactly the same as the HTC one. I prefer the nokia charger because it has much thinner cable and doesn't heat up nearly as much as the original charger.
It is possible there are chargers with pins shorted but rated for <1A, they will either withstand it, blow some magic smoke or stop working after a while.

are there any cheap charging cables out there? in white would be perfect!

HTC modify the Cable to charge with only 500mA, if there is no original One. It doesent matter how much Power the Charger will have. With unofficial Cable it will only use 500mA.
Maybe this effect will only happen on original Kernel.

StarTech USB Y Cable *Double your charging speed*

I haven't seen anybody mention this yet here on the forum, so I went ahead and bought one and tried it myself.
http://www.amazon.co.uk/dp/B0047AALS0/ref=asc_df_B0047AALS09152658?smid=A1AUCPBF2P18HS&tag=googlecouk06-21&linkCode=asn&creative=22218&creativeASIN=B0047AALS0
This is a USB Y cable. Two USB type A plugs to increase charge capacity from 500mA to 1A.
I use Siyah kernel with STweaks to change USB charge capacity from 500mA to 900mA, I am currently looking for a way to increase this to the full 1A.
Only £3.99 from Amazon. Tested using CurrentWidget. Charging now at 900mA.

It's designed for PC's and Laptops which only output 500mA on their USB ports.

Would work really well with the KiDiGi Cover-mate Dual Desktop Cradle, too bad it is a tad to expensive seeing that it is just a cable

Hey i have this cable which came with my 2.5 HDD external case. In some places i need to connect both cables to power the HDD so you think it will work same with S3? Also will it not damage it?

Exactly what I was looking for

this was exactly what I was looking for.. Thanks a lot.. I also has Siyah kernel, and many USB 2 ports available at work, and like to keep my AC charger at home.

This cable won't give you 1A. I guess the second USB plug has no data connection (how could it? ) and without a registered USB device a USB port gives only a few mA of power.

It does work with 2.5" harddrives that need more power than one USB port can deliver. Why shouldn't it work with the s3?
But why would you need that when you are charging your phone at work? It's not like you're in a hurry. It can sit there all day.
And I wouldn't try to charge it with 1A or more just to save a little time. The charger you get with the s3 an the s3 itself are made for 900mA. That's why the kernel is limited to 900mA aswell. You might damage your phone by charging it with a higher current. Sure, there is a safety margin build in but going to the limit seldom is a good idea.

This was correctly answered back in August (above). What does data have anything to do with current? It simply has 2 plugs so that it can draw more current (mA).

No, you can't damage it that way. Electronic devices DRAW current, which means that they only take as much as they are able to. You can plug your phone into a 5A charger and it wouldn't damage it. Too much voltage WILL fry it though.

Are you sure about that?
I've read more than once on tech sites that for example the 2A charger of the iPad will charge other devices that come with weaker chargers faster but that they advice against doing that on a regular basis.
I do use industrial Li-ion batteries (18650) on several other devices and the charger I use for those has a switch with witch I can decide if I want to charge them at 500mA or at 1000mA. Reading in forums that specialize on devices that use those batteries and that have users that seem to know quite a bit about batteries and do extensive testing with sophisticated equipment, the general opinion is, that using lower Amps will prolong the lifetime of your batteries and that too high currents can potentially damage them as of course will overcharging them.
http://batteryuniversity.com/learn/article/ultra_fast_chargers
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
I don't know much about battery technology so I might be wrong. I always had problems to wrap my head around anything that has to do with electricity and electronics in general and have to use analogies to understand and explain how things work in that area. Those analogies don't always apply completely.
The one I have in this case is the following:
I decide how much I can eat. I can eat at a normal pace until I'm full but I can also stuff myself and eat a lot more than I would normally do in a short period of time. I know that the later is a bad idea and won't do me much good but it is possible.
If you are correct with what you said, batteries could draw a higher current than what the original charger is delivering, up to their limit but that could still be too much and harm them.
I don't know. Now I'm confused.

You have a point. I guess it depends on how well the charging circuitry (in the phone) is designed.
The battery itself won't limit the voltage/current (*). It's the charging circuitry that does this. For instance, if you connect the battery directly to a power supply and give it too much juice, it WILL damage the battery. Similarly, if the charging circuitry supplies too much to the battery, then this could also happen. However, it SHOULD be designed with appropriate tolerances and safety margins in mind. Therefore, it depends on how much you trust the hardware.
In that way, I guess charging at 500 mA would be considered safer. That being said, I'm happy plugging my phone into the wall charger every night, whether it's 900 mA or 1A.
(*) I know that Lithium batteries usually have built-in circuitry for safety measures, so they MIGHT have something that limits voltage/current, but I'm not sure.

900mA should be save. After all that's what Samsung gave us.
It's just that some people tweak their kernels to 1.25mA or even more. That's quite a bit higher than the specs and probably close to the safety margin.
It won't even charge your batterie faster that way. At least not when you talk about fully charging it. It will get faster to about 80% charge but after that it will take just so much longer to get to 100% that in the end it takes the same amount of time.
I'll stick to the original Samsung charger or the charger of my old HD2 that I have lying around. Makes me feel safer.

[Q] Power banks and the 2A trick

Hi,
I have several power banks, each with different capacity.
I've noticed that when I connect my nexus to a 1A port, it says "charging (ac)",
but when I connect to the 2A port, it says "charging (usb)".
The usb charging (2A) is slower than the 1A charging.
Though I can understand why usb charging is slower than AC charging,
I don't understand why EVERY 2A charger has to be a usb charger?
Thanks in advance!

On my Anker it is AC. It has a total 3A output, with the N5 using approx 1-2A I think. Check your charging cable quality, it does matter on power banks!
Envoyé de mon Nexus 5 en utilisant Tapatalk

Hi,
tried different cables and different power banks.
Can you confirm that you use A 2A port and it charges as AC?
Or are you using 1A port?

Shortcut The 2pins in The middle of The USB connector it will detect AC. I made a small plug for that

i have xiomi 2A powerbank and it shows AC

That means that your power banks are all designed for Android phones on the 1A port and iDevices on the 2A port. Basically, iDevice chargers put a voltage across the data pins to tell the device what rate the charger supports, while all other devices just short the data pins. You can get a charge only cable to get around this:
http://www.amazon.com/PortaPow-Micr...TYUE/ref=sr_1_1?ie=UTF8&qid=1413824051&sr=8-1
Newer chargers and power banks are starting to ship with what they call "smart charging" or "IQ charging," which allows you to get the full charge rate out of any port without a charge only cable.

Thank you very much, this is exactly the answer I was looking for!
Last question -
I wonder how was I supposed to know that from the specs?
This is the one I have:

Well, it's not a hard and fast rule. Some Android tablets will only charge off the 2A port even though that's the Apple standard. The manual for the battery itself says "refer to your device's manual to determine the proper port" which is a bunch of BS. When that battery pack first came out most Android phones still came with a 0.8A-1.0A charger, and the iPad and other tablets were the only devices that needed higher powered chargers. The newer models of it (http://www.ianker.com/product/A1208011) use the "smart ports" that will charge any device on either port at their maximum rate.

what is your favorite fast charger for the le max 2?

Hello guys,
as the title already says I'd like to know what is your favorite charger for the Le Max 2?
Do you guys all think that the OEM charger from LeEco is the best considering the charging speed or did you find even faster solutions?
Curious for your answers!

ANY qc 3.0 charger, i suppose

Dear collegue. I am yet waiting for my X822. Maybe you could give me some information how long does it take you to fully charge your X820 from 0% and are you satisfied?
regards Olek

If the phone is off, I need about 1h30min. to full charge it when it is not in quick charge. First time I used QC and the phone heated up so that's why I know use the normall method.

For me it takes 1h20min with phone on and the capacity of the battery is correct measured with small USB tool. Fast charging is sometimes 8V and 2.5 A.

got the X822 aka the grey version in transit, couldnt resist it at 222US, ewen thow im not in the market for new mobile, allready pretty satified with the p8max that i like a lot and that dont got any quickcharge tech at all afaik, other then just plain 1.9amp charge cycle., according to my YZXstudio1270 meter, but the 4300mah takes here around 2.15 hour to fill, but slowing down massive the last 5 to 10% like the norm.
that tempo is fine by me, but have also purchased the Vinsic P3 terminator with QC and type C in & out. intended for the X822. seemed reasonable at 28US and with product-specs that shouldnt be to fare for real-world according to reviews.
JUst wondering if you can trick QC3.0 trigger on other devices, got an relative old usb trigger for QC, but no QC phones or at least chargers to check if 9v and 12v can be optainable and be used for ones 12v coreM tablet, just like that and push of an button..

You are sure that the quick charge is actually off.?
when checking on mine X822 and turning the knob in setting < battery < quick charge' to not active.
it still display the same voltage and above +6v to around 9v dynamic.. (its the same when the phone is off)
its like the "quick charge off function" doesnt do anything at all. (am on stock X822 assume its 16s EUI'build)
if you got an usb-meter, try to measure if the voltage actually stays around usb 5v level when turning the quick charge off. (mine it doesnt on stock QC charger)
// digitalnasarma it was on AliE ref CB.

According to qualcomm, it is. My le max 2 shipped with charger EQ-24BUS.
https://www.qualcomm.com/documents/quick-charge-device-list
I'd like a charger for night-time charging. Does anyone know if there are ill effects by leaving your phone on quick charge for extended periods and doing so daily?
And would one risk damaging this phone by using any other 'regular' charger?

Any charger should be safe, just make sure the cable you use has Pullup resistor of 56kΩ, without that 56k chip all kinds of stuff can go wrong. usb A to usb C is a really bad setup and you'll need that chip for protection..

Thanks castuis. Best thing I learned today This (and this thread w/charger links) is good to have.

So Which charger and cable are the best for the price? Original or something else. And where to buy with shiping to EU?

This is by far the best way to buy cables and chargers. You will learn way more than you ever wanted about USB accessories.
I bought the multi pack of Orzly cables , they are the best, relatively cheap... Sturdy.... And won't burn up your phone/house.

Right, but those links mostly focus on USB C standard, not QuickCharge 3.0, which I believe technically violates USB C standards. I'd still suggest sticking to cables confirmed to have the correct pull-up resistor, and if you want to use USB power delivery rather than QuickCharge technology you can also stick to chargers and power banks from that list. I think QuickCharge 2.0/3.0 will still charge faster than USB power delivery though, in which you probably won't find them on that list.
In any case, I bought an 1 port Aukey QuickCharge 3.0 car charger and it seems to work well to charge up to 4 amps. I also bought an Aukey 10000 mAh QuickCharge 2.0 power bank, and it too seems to charge my phone at up to 4 amps. Both were bought from Amazon Canada. I use them either with the cable that came with my phone or good micro USB cables and Tronsmart Micro USB to USB C adapters (which have the appropriate pull-up resistor.)

Using a non-DASH charger and non-DASH cables?

I am thinking about buying the Oneplus 3 since I haven't changed my phone in a long time. I have a few questions about the charging.
Is the DASH charge just the wall adapter? Do I need to have a DASH charge specific USB-C cable?
Can I get DASH charge with a regular USB-C cable to DASH wall charger? (I am asking this because I use long cables because of the location of my outlets and workstation, ~10-15ft)
If I charge with a basic, QuickCharge, or non-DASH wall adapter will my charge speeds be basic or does it revert to QuickCharge (with quickcharge adapter) because it is using the SD820 chip? Also the same question if I use a non-DASH powerbank (I only need a small powerbank not the big ones they are making)?
I am not sure if this should be place here or in the Accessories forum. Please let me know thanks.
Thanks for the help.

1. For DASH charging you need both the adapter and the cable, both are specific and AFAIK there are no aftermarket alternatives.
2. No, with standard cables you won't get DASH speeds. Wires in normal cables are simply too thin to handle high current of DASH.
3. If you're using non-DASH charger and/or cable, you'll max out at about 1.5A, so a bit less than half the speed of DASH (could be slower, depending on hardware used). QuickCharge is not supported, it'll work at standard speeds.
4. Same logic applies to power banks. And DASH capable power banks don't exist (yet?), so it doesn't really matter what bank you're using.

On a side note do you know about the Oppo VOOC power bank (6000mah) since I read Oneplus is not making a DASH power bank anymore. Have you read about its DASH use or where to buy it?

Sadly I don't think this will ever exist ... OnePlus commented about cable length and they said they can't make it longer due to technical limitations (physics ...). High current = high resistance = lower max length.
