[Q] Wireless Charging.... - Galaxy S III Q&A, Help & Troubleshooting

Hi there,
My S3 has a problem with the motherboard where something between the charging port and battery is broken and the phone cannot charge via cord. I have been forced to take the battery out every night and charge it on a battery charger. After recent googles I have seen wireless chargers are available for the S3 but I'm not quite sure how they work. I know the receiver is connected to he battery, but I need to know if this method charges through whatever is broken in the motherboard or if it charges directly to the battery?
If someone with good knowledge or experience of this could answer that'd be awesome!
The charger is a QI branded one on eBay.
Thanks in advance!

[Q] Does a good battery-only charger exist?

And that's the question. Does the Verizon model work well? And by "well," I mean "fast."
I saw a Seido charger in another thread, but there's no way I'm waiting 12 hours for my extended battery to charge.
Thanks in advance for any help!

I use this one http://www.amazon.com/Anker-Multi-Purpose-Universal-Thonderbolt-Revolution/dp/B0058XCV7O
it charges my standard battery in about 2 hours. It even has a usb plug and a micro usb plug so that you can charge your phone while you charge your extra battery. it works with every (android phone) battery i've tried so far. it should work on your extended batteries also. its cheap too!
I've got two of these. Work great!

I also bought the Anker charger but it is a pain to line up the pins each time. I'm terrified I'll short out my expensive batteries!

Thank you. Just bought two for $8.50 total. Hell of a deal!
KORM via the beast known as the Rezound.
Just picked up the Anker charger - beyond happy with it, but I doubt it will last the life of my phone. I was just happy to charge my standard and extended batteries at the same time.
The USB port did not seem to have a full charge pass-through, sort of like charging from a USB adapter in my car. Seems to provide a trickle charge.
Otherwise very happy to have it.
Thanks again guys, for the suggestions.

I have a charger very similar to the one suggested by SamXp. But I got the package deal that comes with a 1500mah battery included, made by HyperCel: (due to the rules I can't post links yet)
The battery was complete garbage IMO, it's not a solid "slab" like the OEM one. The part where the charging pins connect is separate from the cells and pretty much just wrapped in flexible plastic. Definitely not going to trust that in my phone.
I have a question though: I seem to have issues with the touchscreen responsiveness when I'm using USB output charging port. Anyone else seen this? The OEM charger (and my laptop's USB port) don't have this issue. It's annoying because I have to unplug my phone to shut off alarms, answer calls, etc. Does the anker charger have this problem? Could someone who owns one test for me? I've tried with both a generic micro usb cable and the oddly-shaped HTC OEM cable with the same results.

[Q] Red x when charging. Help!

Recently I traded my galaxy nexus for a galaxy tab 10.1. But whenever I plug it into a computer or an outlet there's a red x on the battery... it charges reallllly slow. I left it to charge for nine hours from an outlet while turned off, and it went from 5% to 55%. WOW. That's really slow. So I thought that the problem is the cable so I bought a new cable that came with a car adapter. And it worked like a charm in the car. However when I traded I kept the 3 pronged galaxy nexus charger. So anyways I arrived home happy, but I wanted to test it in the computer... Red x again. I tried the wall outlet, again with the x. I tried the wall outlet with 110v and 220v still red x. Then I looked at both outputs on the wall charger and car charger both had the same output which is 5volts and 1A. Then I looked at the input and the car charger was 12-24VDC and the wall outlet was 100-240v and 50Hz and 0.15A. I need help please.
I have 3.2 honeycomb and P7500.
I think that this is an internal issue software wise.
If you need anymore information don't hesitate to ask.
Thanks in advance

On stock settings u wont be able to charge the device connected to ur computer and u will get the Red X on the battery icon! Therez a small tweak to activate that feature to activate charge on pc connect but u will loose the mtp connection. As far as this issue... Seems to be a battery proble. Still try to flash and get to stock to confirm.

What do you mean by loosing mtp? Also I'm a bit noobish at this because I just switched from ios. So can you dumb Down what you said a little. And what do you mean by "still try to flash and to get stock to confirm."
Also my problem is wall charging.

I get that if I try use galaxy nexus charger, however if I charge my galaxy nexus with the tab 10.1 charger I have no problems, make sure your using the correct charger, and for the slow charging I have a USB extension cable if I use that it can take up to 12 hours for a full charge
By charger do you mean cable or outlet?
Sent from my GT-P7500 using xda app-developers app
simplest answer is that the red X means that you're not supplying enough voltage to your tablet. You need 2A (A = Amps), computer USB ports generally do 500mA (1/4 of what you need). Phones usually need less. So the reason your tablet won't charge off the phone charger is because it doesn't supply enough voltage; the phone does fine on the tablet charger because it's just oversupplied (don't worry, your phone won't be damaged by this!)
So what you need is:
1) an original charger for this particular tablet (the cable probably isn't the issue, but I've seen cables that can't transmit the full voltage. The nook color is a good example of this)
2) a 2A charger - can't promise any particular ones work though...
3) (and this is the one you should do): You're on XDA. This is a place for folks who root and install custom ROMs on their devices. Most of the ROMs have USB charging built-in (in the Kernel; don't worry about what that means). Install a custom ROM (I'd suggest AOKP). Problem solved, plus you've increased both performance and functionality of your device exponentially. If you're not willing to do this, XDA probably isn't the place for you anyways.

The outlet , the one for my tab is twice as big as my Gnex one, I guessing they both give out different power, get the official charger!! like I said I can replicate that any time I want by using the tab cable with my Gnex outlet,

I found a solution to a problem that was really vexxxxing me. One of my chargers was working and the other (longer lead) all of a sudden started showing the red cross. Ahhh. The solution (http://www.androidtablets.net/forum...galaxy-tab-10-1-not-charging-brand-new-3.html) was to blow very hard on the 30 pins of the charger and hey presto - started charging again without the red cross.
There are solutions to this problem with quite a few custom ROMs. Task's ICS for example has this patched. I am quite certain there are others.

Phone charging still battery decreasing

Phone was plugged into mobile USB debugging enabled and was developing through ADT.
is this okay or there is some problem with my mobile?

Check what the current_max is when it is charging using this app: http://forum.xda-developers.com/showthread.php?p=36124435
It happened to me too once. When I checked, the phone was charging at 100 when it should charge at 1000. Unplug abs re-plug the USB from the phone when the charger is connected to the mains. That should solve the issue. :thumbup:

i had this problem too, which i suspect that the charging port on my phone is damaged. anyways microusb ports usually tend to wear out over time and separate from the mainboard slightly giving a intermittent connection.
now i am using a wireless charger and it is charging much faster then my phone on mains.
That is 500ma on wireless vs 1A on wall.

Wireless charger? Whaaaat? Which country you're in? I thought that, it hasn't launched yet.. Atleast in India it has not.
Anyway.. Now I was charging through the normal charger via plug.. It works just fine..maybe in USB debugging my phone was constantly awake.. That may be the problem?

You can perhaps try running a battery calibration app and reset the battery stats to fix?

[Q] Galaxy Mega 6.3 EXTREMELY slow charging.

My wife has a 3 month old Galaxy Mega 6.3 and it will not charge correctly. It will not change when it's on enough to keep it on. Last night I had her charge it while it was off and after 12 hours it was only at 48%. We have tried new chargers, new cords, taking the battery out for a while, nothing is working. Any ideas? It's completely stock, no root.
Hi .. make sure that your chargers output power is 2.0A don't use chargers with 1.0A or 0.7A output or it will charge slowly .. and try to use a short cable ..shorter is faster .. If this didn't help maybe the problem is with the battery it self buy a new one

Yeah, we used an oem charger and cable and a charger that puts out 5v and all the same charge rate
I think 5v is too much & dangerous for the phone maybe it'll ruin your battery

Hi..the original charger for the mega 6.3 is 5v with a 2.0A charging rate, can you test another battery from a friend to see if it is the battery.
I literally have never seen anyone with a mega besides her lol. My next plan was a new battery, but I didn't think a 3 month old phone should need one yet.

Maybe go to your carrier were you got the phone and explain what has happened and maybe they can give you a new battery or if it is a hardware problem..they can maybe give you a new phone.

Hello SumCanadianGuy
To be sure to get fast charge with most Samsung smartphones, you need an original Samsung charger AND a fully connected (4 wire) USB cable.
Charger outputs 5.3 to 5.7V and pin 2 and pin 3 (data pins) are shortened together inside the charger to indicate the phone that he can draw fast charge current.
All my original Samsung wall chargers are rated only 1A. It doesn't mean that they can't output more current for a short time. I get fast charge every time.
If either your charger isn't an original with pins 2 & 3 shortened, or your cable has no data connections, you won't ever get fast charge. By example, if you try to use a powerful 2A or more iPad charger with your Mega, you won't get fast charge, just because the other world doesn't conform to USB
If you can, try an original Samsung wall charger with an original Samsung usb to micro usb cable.
Hope this helps
I have same problem with my Samsubg Galaxy Mega 6.3
I tried everything (change battery, cable, charger) but nothing help.
Charging is slow but during all night it could charge to almoat 100%
It only could be hardware failure...
If you want to see power of charging install app Galaxy Charging Current Lite.
Power of charging should be 1900 mA and I could get only 300 mA...

Slow charging with phone turned On

Hello dear fellows- i am facing a very strange issue on my lg g5 (850).
I have a third party charger (Aukey QC 2.0) with a usb A to Usb Type C cable. This charger never failed me once on any of my Samsung phones. Quick charging always worked as it should but with lg g5 its charging speed is very slow. According to Ampere app its just 310 mA. After connecting this charger it even shows fast charging notification but fast charging is not there.
Today i've decided to charge it after turning it off completely and guess what... It was charging really fast as it should while turned On.
Now i am confused whether it's LG's software which is preventing 3rd party cables/chargers to charge fast while turned On or is it something else.
Any input guys or similar experience?

It's always possible an app is using a lot of battery while you're charging. So the phone charges slower. Question though, why don't you just use the provided charger from LG?

Unfortunately, the LG charger was lost last week during my travel so by chance I had this Aukey charger lying around which is Quick Charge 2.0 supported so i am trying to accomplish the original results with it until i'll get my hands on a QC 3.0 compatible charger.
Hm, my Aukey Quickcharge car charger even works fine with my phone.
Make sure you aren't using the phone while charging it, it will always charge much slower.
I have some doubts on my data cable. Will try to swap it with another one and will test again.

I can confirm that the LG software does not prevent fast charge with 3rd party chargers and cables.
I'm using a 3rd party QC 3 charger with a 3rd party cable, and fast charging is working just fine when phone is powered on.
And in Battery Monitor Widget I can see that it actually is fast charging and is using QC 3 to throttle charging amperage.
However I've experienced a couple of times, when changing cable in the charger, that it wouldn't fast charge. It was solved by removing the cable from the charger and connect it again, and then it works just fine afterwards.

Seems like slow charging has something to do with the heat/temperature of the battery or overall phone. If i try to charge it when the battery temps are around 30 then it charges really fast but if the temp is above 30 then software somehow restricts the fast charging to avoid any damages.
I am not sure if the above analysis is valid but my observation has lead me to this point only so far.

I learned 2 things from my testing using ampere and a drok USB current meter:
First, ampere isn't really that accurate when it comes to this phone and charging currents. It was consistently about 200mah off.
Secondly if the phone is even somewhat warm, it will limit the charge current to ~300 mah with the screen on. However if you turn the screen off, it returns to full charging speed (1.8 amps in the case of my charger) I think it is some sort of thermal throttle to keep the battery from getting too hot.

That really is frustrating. I always see fast charging when plugged in, although it definitely is not fast at all if you are using it or have the screen on .
Are you plugged into a wall outlet directly? Not an extension cord? Sounds like a warranty replacement may be in order, it's possible there's something faulty with your USB C connector.
Have I not voided warranty with unlock? thanks
Tried with xiaomi charger and it works, no joy with original.
Must be faulty lg charger using same cable
I have LG G4 and I was facing the exact same problem. The phone would charge very slow while screen was on. Once I let the screen go off the phone charged at the expected rate. It seems LG is incorporating some serious throttling in their phones.

I think you can not fast charge while the phone is turned off. Maybe someone can start another thread where we can compare battery logs because this will help to see the amount of time used for charging. Is there any way of seeing if the device is using QC 2 or 3?
LG G5 on 7.0
I just got a Warranty phone because of GPS pins lost contact with case. Now I'm getting the slow charge message. I just found if I flipped the USB C over it fast charges. Just thought I would share though doubt y'all wouldn't have learned this by now with all of the testing you've done already.

I experienced that too. Isn't it strange?
Also, I experience with some chargers, the phone will just start charging for some seconds and then act as if the cable was unplugged and then start charging again. I don't know why. Anyone experiencing this too? In this case, it didn't help to flip the cable...
So disappointed with my G5 now.
Was great to start with now it's slow charge. Got new batteries but the same. Will charge off till about 5/6% then switch on. Lovely phone now just useless. Even got the phone and amp modules. Lol

This is a problem with the make of the charger. I have some Choetech QC chargers, and the programming in the QC is faulty. Some safety mech kicks in, turns off the charger, then turns back on again, over and over. I have some Tronsmart chargers and there is no issue. Of course, the OEM LG one works fine too.
