[Battery] External battery power via USB - Galaxy Y GT-S5360 Accessories

the reVolt model DX-P112Ro batt pack with 4 AA cells unfortunately cannot charge the SGY. maybe it can be fixed with CYANOGEN mod though.

can you give a link or description of the product you are talking about?
I use my own portable charger which works :/

revolt pack
http://www.amazon.de/revolt-USB-Bat...r_1_17?s=ce-de&ie=UTF8&qid=1327238515&sr=1-17
ext batt pack - not too compatible with many devices

Ahh.. weird.. :/
check the voltages..

already did.
I guess , the SGY checks some resistor or sth. before charging.
same crap with i-phone. f*cken Steve Jobs wants you to buy his charger only.

some devices do that but not SGY.. I told u.. my self made portable charger works..

voltages cant be that bad. it charges a garmin nuvi without problem via USB. gotta recheck though.

how to get it?

I guess that's hardware error.

It must be the voltage. It should be a standard USB voltage which is 5v.
Some other device has a wide range of input voltage thats why your garmin works with it.

most likely friggin voltage. a different external batt, which works on SGY here delivers 5.2 Volts.

Well, when I use my excalibur while charging and specifically using wifi...that thing it's a portable heater . It really gets hots on the battery .
Regarding the charging volt, It's 12V to charge.

There may be a little misunderstanding here. I think OP is referring to the maximum voltage which should be applied to the phone.
A car charger requires 12VDC in order to operate.
A wall charger usually requires 110 - 220 VAC in order to operate.
In both cases though, the outpuit to the phone is in the region of 5VDC with a maximum current draw of ~ 1.0 Amps.
Most cell phones require about 5VDC in order to charge.

most cell use 3.7V to 5V tht is when it is converted to 3.79 to 5V from 110~220V with transformer.. so how much "output to the phone" is needed for charging HTC Excalibur...as i hav told before i hav been charging using 5V (converted by transformer) n i m not sure whether it is the required volt or not.. n i think my previous battery died because i used it while it was in charge...

The output to the phone is usually about 5 VDC. For example, the charger that came with my S621 has a rated output of 5VDC with a maximum current draw of 1.0 Amp. The majority of cell/smartphones seem to use chargers which have a rated output of ~5 VDC. The actual amperage, or level of current flow, depends upon the individual phone's design/circuitry. Another point: A USB port operates at 5VDC. It as you know, will recharge the Excalibur, as well as many other phones.
I'm not well versed in circuit design, but I do know that the maximum voltage of a fully charged cell phone battery is ~4.2 VDC. I presume that the individual phone's circuitry modifies the input votage from the charger, to a level which will safely charge the battery. (And cut off the current to prevent overcharging).
I presume, when you mention "transformer", that you are referring to the typical cell phone wall/car charger. A simple transformer would probably be a very efficient means of frying your phone.
As for using a phone while it is charging, I cannot really comment. I use my phone while it is charging only occasionally and even then, for only a short period.
Mr. Clown refers to the fact that his phone gets quite hot when used while charging. That may shorten battery life. That, in turn, may depend upon what the phone is being used for at the time. Obviously, more functions in use = greater current draw = greater heating effect.

USB Fast Charge mod

Hello I was wondering if there is a mod to have usb fast charge when plugged into the comp. I just came from a Inc and there was a mod flashable through cwm. it was very nice. it charged the phone just as fast as an outlet, if not faster. is there a mod?
thanks
Interesting... I'd be interested in this as well.

. he made the incredikernels and the incredicontrol app. tried to use incredicontrol app just for fast charging but didnt work since the kernel doesnt support HAVS or SVS. Im on Francos btw
Imoseyon said once any speed charges were done by taking code out that slows it. Nexus doesn't have it in kernel now according to him so not likely.

Would there be a way to selectively trigger AC mode as opposed to USB mode?
just asked this in the IRC chan and few devs said doing this could mess up your computer system. point of the hack would be to trick the cheap car chargers into giving u the full charge, not the computer.

Not many motherboards have USB ports capable of supplying current in excess of the spec 500mA.
Research modding your (car?) Charger to be detected as AC charger instead of USB.
Sent from my Nexus Prime.
What about a mod that allows the 3 pogo pins to receive more than 500mA(recognized as USB)? That seems ridiculously low and is far more relevant/needed. If you want to charge through the pogo pins you are just SOL.

I haven't seen a device that can't do 1A over USB in like a decade.
Hell, even non-PCs have no problems with it. I've done it off a Wii before just for fun.
A lot of newer motherboards can even do 2A over USB (to charge iPads). Most ASUS boards in the past 2-3 years have this as an advertised feature (asus ai charger).
Very interested in this actually. Not so much for USB/AC charging on a computer, but for MHL AC charging.
With the current MHL adapters (even when plugged into an AC outlet), the Gnex reports USB charging. To make maters worse, the screen does not shut off on the Gnex. After an hour or two your battery will die. 500ma is just not enough.
The MHL spec says that 500ma is the charging spec. However, I tweeted with Tim Wong:
http://twitter.com/WongTim
He is the president of the MHL association and he said 500MA is the minimum, not the maximum. My quess is that the Gnex won't try to draw more than 500MA since the data pins can't be shorted on the MHL connector.
I think the MHL adapter will provide for more current, just like most laptops and desktops.
With this mod, it would be nice to tell the Gnex to AC charge. Tim suggest that the phone should not draw more than safely required so long as the voltage doesn't drop on the MHL adapter/MHL tv.
I think the Gnex, by design looks for the shorted data pins and doesn't try to push the envelope as far as monitoring the voltage drop on a USB detected power source.
I recall reading about some smoking/dead phones from fast charging mods. Thanks but no thanks.

I came at this problem from a different angle and accidentally found a solution for you. I have an iPad and it wouldnt charge from my PC so did some research and came up with this:
http://event.asus.com/mb/2010/ai_charger/
Its a free driver from asus that increases the max amp on USB bus. Supports most mobos and works awesome on my PC and dell laptop, I can now charge the iPad on there.
It also has the benefit of fast charging of my Nexus. Double win.

[KERNEL PATCH] Force AC (fast) Charging

This was a pretty big hit with the gnex and nexus s guys so I figure that I would extend it to the aries series phones:
This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This patch allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
Some roms (AOKP) have also implemented toggles.
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
You may also use IncrediControl (free) to toggle, however it does not fully support the aries series phones so features like voltage control do not work at this time.
https://play.google.com/store/apps/details?id=com.incredicontrol
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Here you go. Good luck have fun:

When it is enabled, the phone detects all chargers as AC and your current draw is dependent on the source you're charging from. For example, if you're charging from a 1A usb source (such as a powered hub, car charger) you should get currents close to that from a wall charger. With it disabled it reverts to the factory detection of charge sources and anything detected as USB is limited to 500mA.
I use the original Vehicle Dock from Samsung (ECS V968) for holding my Phone on the Windshield in Car!
Plugging in my phone normally switches over to Sound redirection (by xcaliburinhand) and charges via 12v Car plug!
The charging isn´t working anymore !!!
Phone directly on 12v car plug: CHARGING !
Phone on USB port: CHARGING !
Phone on Vehicle Dock which is connected to either 12v Car plug or USB port : NOT CHARGING !
Ive tested with other phones (stock firmware) and it works ...so the car dock is not the problem!
Im using WeUI 0.9.8 with Semaphore Kernel 1.0.0
I dont know whether fast charge may be the source of that problem.
any idea ???

Not bad at all. The phone will not charge any faster than it would on AC charging, therefore its no worse for your battery than charging from an AC charger. I do not believe in increasing the charge current to the phone beyond what the factory specs are.

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.

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.

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.

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.
shamez23 said:

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.

Hey guys,
So yea, i cant charge my phone up. It had smth to do with the microUSB slot on my phone. When my phone had juice, it detects the charger and then doesn't detect it again back and forth all the time.

Samsung charger outputs 0.5A power compared to Xiaomi and Apple charger head (which I've been using) that uses 1A output.
I heard the more current the faster it charges batteries. Ive been using those 1A charger the whole of my life.
Currently, i have to use Samsung USB cable and Apple's charger head to charge this phone up. Others won't work apparently. All i get is charging, then discharging, vice versa
I dismantled the phone also to see what might be the problem. Below the microusb slot on the pcb mainboard, theres abt 4-6 lines. It looks like small metal wire that doesnt move. But for some reason 1 of the lines were somewhat bronze or dark brown in colour. Any ideas?

Be sure this chip made for 0.5A not 1A which will cause that browny wire (more heated)
You should fix it or replace the chip

Sadly, i tried using many things including a 4 hub USB Port and a 0.5A USB travel adapter (too desperate can't find anything else )
and the ony thing that works is the pic below. Yes, thumb required for chargin'

Hah, ofcos im not doing that. I had to move the cable abt and leave it like that. Any movement will interrupt the charge.
I dont think repairing and paying money close to a secondhand Galaxy W is worth rly.
