Usb otg and charging at the same time (kinda solved) - Galaxy S 4 Accessories

So as the title says ive kind of found a way for the s4 to be charged at roughly 500-600 mA while using usb otg.
So how did i do it?
!!Tutorial can be available if anyone wants it!!
By using the terminals on the back of the phone for the qi charging reciever i connected a usb lead to these terminals, providing a charging input to the phone, whilst leaving the micro usb port free making otg still work.
Tested on a ks01lte (i9506) device running the last CM12.1 nightly release

While it is a great achievement, it is rather limited in use.
The only reason, for me, to have the phone's USB port while charging is so that I can hook up a game pad through OTG and play games without the battery dying on me.
Unfortunately 600mAh would not provide a sufficient enough current for this to happen, the phone would slowly discharge due to it using more power than it gains.

Can you not charge at more than 600Mah or is that the most the qi terminals will take?

When I last looked into doing this, all the cords I found only power the device that's connected, not the phone. Has anyone gotten the cord in the link and tested it? Will it charge your phone?

Good Car Charger?

Does anyone know of a good car charger? You know, the kind that plugs into your cigarette lighter socket.
I had one at one time but it died after only a week of usage.
I got this one and it works fine with a spare microusb cable. Best part is that I can now have two phones charging at once.
Thanks!
At only $8, that's a steal of a deal! Just bought it with free two-day shipping.
Should have checked Monoprice

There used to be a twin plug one (I have it) but I can't find it now.

In my opinion... I have wasted alot of $ on trying to get away cheap on a car charger. By far the best one is the official verizon one. It charges to 100% from 0 in less than 2hrs and charges while I am navigating, wifi tethering and using bt at the same time. Well worth the extra cash.

I got a similar one, but it has one port meant for an ipad/tablet, which outputs 2A - that is helpful for when I am running car navigation and wifi hotspot at the same time. I also had to get a charging-only usb cable because regular cables would trigger usb storage mode on the phone.

To bad the Charge won't draw more than ~0.8A... Also, it is the charger causing the phone to go to mass storage mode, not the cable. A microUSB cable is a microUSB cable, and if the cable says "charging only" they have the data pins shorted out (I believe that's what is done) and it really isn't fixing the root cause of the issue.

The only way you could speed up charging would be to modify it via the kernel, or try to force load a module that does the same thing. Odds are the fastcharger script just gets the system to recognize USB charging as a wall charger. Either way, I wouldn't recommend using anything that says it'll make your phone charge faster unless there was SIGNIFICANT data to support the claim as well as evidence that it doesn't harm the hardware.
Charging the battery too fast is very dangerous too. I tried "supercharging" one of my batteries and it almost caught fire.

It could be the cable, but the odds are against that. The way to tell if it was the cable would be to try it in another AC charger to see what it does.

I tried a 2.0 amp USB car charger and the factory cable.. .my battery got really hot and didn't charge at all.. .not sure why but the 1.0 amp charger seems to work the best...I have seen a 5.0amp at Walmart in the car department.. .but I don't feel like experimenting with that

Samsung smartphones and Tablets charge in std mode (Charging USB) unless the two data wires are "shorted". (I have seen it done directly in a high speed charge only cable or in the Samsung chargers. Some say they use a resistor.) When the data pins are "shorted", Samsung switches to high speed charging. (Charging AC). I have been harassing a factory overseas for a dual car charger (2100mA) with one std. Port (iPad) and one Samsung port. It should be available soon.

I haven't tried another car charger personally, but can vouch for the Verizon one. Always works for me and I just leave it plugged in the lighter outlet in my center console so whenever I need it, it's easy and quick to plug in the phone. Also has the scrunchy style cord to keep things neat. But at the same time, it makes it more difficult to use the phone while it's plugged in as it keeps wanting to pull back lol

[Q] OTG and Charging

I recently got a Nexus 5 to replace my old Nexus S and really like it. I am having one challenge that I was hoping for help on:
I have got OTG working with stickmount fine, but I am trying to use this Y-cable to charge while using it and I can't get the phone to charge from the cable at all (with or without a USB drive connected). I have been able to get other, non-Nexus's to charge from the cable so it isn't the cable that is the problem.
I am rooted but running a stock kernel and rom - any ideas why it might not be working or if there is a custom kernel that has enabled the capability otherwise disabled in the phone?
Probably you need a modified Kernel like Nexus 7

I had OTG charging on my Galaxy Nexus as well as the N7. I just tried it too on my N5 with Elemental X kernel, no go. That's odd no one has come out with this feature yet if that's the case as I'm sure it's very sought after especially with people who have the 16gb model like myself that hook up to external hard drives to save space on the phone but they need external power.
Otg + Charging is also very useful when you are playing games using GamePad

If you are using a USB Connection Game Pad via OTG, graphics heavy games use too much battery and usually you can not play for long. This also increases the importance of such kernel for Nexus 5 as well. Nexus 5 have smaller battery but it can play decent Graphics.
I do not like Game Pads with Bluetooth connectivity as they have control latency or lag and your moves are not as quick as even the touch screen, where as you use Game Pads to improve your control moves and probably make them better than touch screen.

I think that Nexus 5 USB Port is 5 Pin and not 11 pin like Galaxy S4 or Galaxy S3. Can someone please confirm this?
If this is the case will be still be able to Charger Phone and do OTG concurrently or simultaneously ?
Yes but I believe it's something that has to be addressed at the kernel level.
I use a powered USB hub and even though the phone doesn't show any charging animations, going into the battery info screen shows it is charging (though it doesn't say usb or ac, just charging)
from what I have seen it's even less than trickle charge.
USB flash drive mounted.
Screen off
Battery goes up about 1% every 10-15 minutes.
So clearly current is being passed from the hub to the phone. Just not a lot

I am not sure but can we use QI Wireless charging along OTG. I have read somewhere that it charges but there is a bug in Kernel due to which it does not know that battery is being charged there is no animation or text to show that battery is being charged. Another concern is that if OS does not know about charging and battery is being charged is it not dangerous can it not overcharge and below the battery etc.?

I use exactly the same Y-cable from amazon as avalpert. I connect my USB 2.5" harddisk first at the Nexus charger and let it spin up. Then i connect the OTG cable to my Nexus 5 (rooted stock ROM & stock kernel). The battery icon in the status bar has no charging animation but in settings it says its charging. Around 1% in 5-10min. Even if the screen is on.
@ avalpert: U could check the current of your usb drive in the manufacturer's datasheet and subtract this from the current, your charger is able to provide. My Nexus 5 charger can output max. 1.2A at 5V. Maybe you're using another model and there is just little current left to charge as Alex remarked.
But the difference is I was only powering a flash drive which uses next to no power. And still only 1% every 10-15 minutes.
My best guess is that because otg is enabled. The kernel is not able to tell what type of charging type (ac or USB) is connected so it just enables trickle charge as not to cause any problems

I can confirm this, I use a powered 7 port USB 2.0 hub, and with the original PS: no charging.
Now I took another PS that puts out 2.14-1.7A @ 6-7.5 VDC, and hey presto, charging the phone!
No indicator in the status bar (top screen), but when checking the battery status it clearly states "CHARGING" (see picture OPLADEN 95%)!!
And it charges pretty fast too.....
The mouse is working, as wel as the USB stick is recognized and working!!
The ONLY worry is about the charge....... is 6-7.5 V a battery killer? :fingers-crossed:

I know it is up to the device (Nexus 5) that how much load it will put on the adapter to consumer out of 2000ma or 2A. On the other hand I have read somewhere that even most 2000mA USB Chargers just give 500mA in the beginning and due to some data pins activity they start generating 2000mA. If this is the case then Nexus 5 will force only 500mA or so from the charger that it is not compatible with. If we use some adapter that generates constant 5V 2000mA irrelevant of communication on data pins like the ones with 3.5mm pin which does not have any data pins, at least we are guaranteed that, at least full power is coming out of the adapter at all times.

I am given to understand that it has nothing to do with the "intelligence" of the charger, but with basic electrical principles.
That would imlpicate that if a device requires 500 mA, the charger will supply 500 mA, if the device would require 3000mA, then it would supply 2000 mA, being it's maximum current (flow).
As far as I know, a powersource ONLY generates a flow (Amps) up to it's maximum limit, if it is connected to a consumer (device). No connected device / consumer leaves no flow to be generated.
Please correct me if I'm wrong.
Added to my little test earlier today: The phone didn't get hot, at most it would be slightly less cool..... for the PS the same.

[Q] USB charging of WiFi model

I tried the cord that came with the tablet, and my other USB cables - same results with all. My Note Pro won't charge via USB at all - when I plug it in battery status says "not charging" and it keeps discharging, while idling with screen off. Only AC adapter works and battery status changes to "charging". Any ideas?
You can't charge the tablet off s usb port. Draws too much current. Some motherboards have an option to turn on a special charging function for a usb port, but if you had that you would probably know.

Stock kernel on the Xperia Tab Z must have USB charging enabled. This is an exception rather than a norm I would think, with OEMs probably choosing to disable this as a safety measure (or so i've read).
Until a custom kernel is developed for the Note Pro we'll probably not see charging over USB.
The problem is still the max output from the USB port, which is 5V 0.5A , you'll notice that the charger for the this tablet is 5.3V 2A.
I'm an electrical engineer not a computer engineer, so I'm not sure how a kernel would change the max output current supplied by the PC. This has actually piqued my interest, I'm going to do some tests and see how much current the port can push. I'm betting the data lines on the plug send some information about what's being charged.
Maybe I'll build an adapter that that let's the tab pull a full 2A from the port.

This review says Note Pro 12.2 can be charged via USB - it's just slow. As I mentioned in the OP - when I plug it in via USB cable the battery status says "not charging" - could it be it's actually charging, but due to low current the device itself doesn't recognize it's being charged?

It kinda works - with tablet completely idle and screen off it charged about 4% in 1.5 hours via USB 3.0....don't think that's helpful to anybody. Hopefully, someone finds a way to push more current through USB 3.0 port. Would be nice to eliminate the need to use AC charger.
I had mine hooked up to my laptop (Asus N76VB), it didn't charge according to the indicators (neither do my TabPro 8.4, Tab 3 and Tab 2, nor my TF700T), but the battery didn't drain either while I was using it. It stayed at 56% for 5 hours whilst browsing, which it really wouldn't do normally. USB 3.0, no additional settings enabled on the laptop, all Sync and GPS turned off on the tablet.
My TF700T literally said in the manual: "Charging from USB can only be done with the device turned off." I'm sure that applies to these tablets as well.
On the upside, my 15600mAh aSolar powerpack charges the device! :victory: (It can't charge my Tab 2 or TF700). I'm really, really pleased about that!

USB charging issue

Hi all,
My friend's OPO does not charge when connected to the USB port of a computer. It is stock, unrooted, KK 4.4.2.
It charges fine when he charges via the wall charger. My OPO charges fine out of the box, with USB on the same laptop and port.
He does not want to factory reset and I am at a loss here. Please advise what I need to check here.
Thanks!

He can buy a universal adapter for the charger. They're pretty cheap.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

The front panel of my pc case has usb ports that has trouble recognizing or charging any phone. When I plug it in, the phone will show it charging but the battery continues to drain or I can't access the sdcard. Not sure what causes this, but when I plug my phone into the usb ports in the back that are connected directly to the motherboard, then there is no problem.

Thanks for the reply but that is not it. My OPO charges fine from the same port and the same cable.
Anybody got any info on this issue?
Uh, I'd say factory reset or don't worry about it.
Not sure what you expect to hear. But that's probably the first plan of action. Especially since yours works fine.
Opo has higher power requirements. You may need a cable with a 24AWG or better rating (lower allows more current).
Does it work with the stock cable?

My OPO works with any cable, though time to charge is the best on stock cable. But my friend's OPO doesn't charge at all. Even on stock cable.
Unable to make sense of it at all. I may sound like a simpleton, but maybe there is some checkbox I ticked somewhere which is preventing this? UGH!

The phone will work with any cable. Worst-case the cable's resistance and diameter will reduce the maximum charging current significantly but it always will charge the phone.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

No USB port has that much current except maybe for highly specialized ones. USB2 is rated on 0.5Amp, USB3 on 0.9
Of course the phone will take significantly longer to charge or may even discharge when used while plugged in.
I can say "me too". My one also didn't charge from powered off PC while Nexus 5 plugged in the same PC with same cable charges fine.
When PC is powered on, One charges intermittently. I.e. I plug it in, it charges for some time and then stops. "OS monitor" shows "discharging [USB power]" state.
Any thoughts?

Cannot charge OnePlusOne via USB
I have the same problem.
The problem seems to have started AFTER upgrading O/S to Cyanogen 12.0.
Cannot charge via USB either from my note PC or Mobile BatteryPak (1.7a).
Above comment that 2a power is required is surprising, as I thought 1a is standard. Maybe there is some Cyanogen bug here?
I found in some Forum to make of SETTINGS - STORAGE - USB COMPUTER CONNECTION, but I do have this setting, and still cannot charge the computer.

In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A)

It will charge very slowly but will charge faster if the device is off. If you're using it while it's charging it's like filling a bucket up with water that's got a hole in the bottom. It fills up. But slower than it would if there was no hole.
As for the battery pack I have a 2.0a EE Battery pack and it works fine so it might be related to the analogy above.
Sorry to bring up an old topic, But its still hanging and non has really come up with solution. So i thought let's bring some light to it.
My dad has encountered the same issue the other day, I'm basically not much PRO into fixing things like this but by turning on/off USB debugging while connected to PC and also turning on/off Developer options does makes it charging through PC again.
Previously it was charging by PC, but dad has messed up something internally and asked me for help, so this lil so called tricked work for me. I hope this will help others to.

OTG Cable + Charging for G900T

Hello,
Has anyone been able to find a cable or dock that provides OTG support AND can charge the phone at the same time? This would be for a G900T
Thanks!
For whatever it's worth, I tried a Valarm cable on a G900V S5, no luck charging and using as a dock. The cable seems to work on the S4 though.
I searched for a long time before I found the answer to this. It is unfortunately not possible to charge and use OTG at the same time.
A USB wire has 4 wires inside it. Normally two wires are used for data and two for power (positive + ground). When it's used in OTG mode it uses all four wires for data meaning there are no available wires for charging.
The salutation I came up with was to buy a wireless charger. The S5 doesn't have build in wirelesss charging abilities so you have to buy both the charger and the reciver (I paid about $25 for both pieces on amazon). This is the only way I've found to charge the phone and use OTG at the same time.
There are also guides to attach power directly to the back of the S5 where the Wireless Charger would attach, but then you'd need to have wires running out of the back of your phone. I also didn't have much luck with this approach but I also only gave it a few minutes of trying with my volt meter.
Another approach is to get an OTG wire that you can switch between charge mode and OTG mode, but again you can't do both at once.

P.S. feel free to correct me if I'm wrong. I spent a few days on google before I came to this conclusion.

id love to argue with your post (not really, just thought it was funny to say that), but youve done your research man!!! I ordered an OTG cable for rooting my chromecast, so ill test it out. I bet youre right as your logic seems to be very sound. Thanks for the info sir!!
Hi,
I'm also interested in getting my S5 charging and using OTG at the same time.
I have this usb hub which can achieve this with my Galaxy Tab S, but not with the S5.
Isn't there any kernel or ROM that can fix this ? ( I currently have stock 6.0.1 ROM on G900F )
I can't believe that no one on this planet actually achieved this on S5. I red about some Motorola owner who fixed this with a kernel mod btw.
thank you in advance for any help on this !

I have studied this also and until devices basically come with a dual charging circuit so voltage and data can go in and out But you are also correct, No arguments on that.
