[Q] Phone won't charge properly - Galaxy S 5 Q&A, Help & Troubleshooting

I'm at a complete loss. The other day my phone was charging fine. I have the original charger for my s5 and I went to visit my family just a town over. When I got there my phone would not charge correctly. It would charge extremely slow. I'm back home now and while charging I'm still losing battery percentage. I downloaded battery monitor and it says plugged in discharging and the mA flow says -758mA right now but it keeps fluctuating. A while ago it was actually in the + but that was a while ago. At my work there is a charger that is also a 2.1Amp charger and it charges my phone fine. I understand it is my charger but I have used a plethora of other combinations of usb chargers and ac adapters but I'm getting the same result. All these ac ports are also 2.1 and I have another usb cable from my s4 so it should work. What can I do about my chargers to fix this issue. I have a voltmeter but am not to apt on how to use it correctly. How can I see if my port is actually outputting the 2.1? If I can find this out I can deduce that it is my cables and not the ports. I will provide any further information requested.

USB power supply

I am using the Cingular 8125, which I think is the same as the Wizard. Since I travel frequently I thought I could buy one of those USB power adapters (with a USB connection) and recharge my 8125 through the included USB cable. This works fine with my PC. A strange thing happened: the battery indicator told me the battery was charging. the 8125 had about 50% left when I hooked it up, and when I checked later after I disconnected it, it said 87%. However, this number went down in fron of my eyes, about 1% a second until it stabilized at around 45%. I think, the chrager did not work at all! Does anybody know what the requirements for a USB charger are to work? The one I have says 5V, 300 mA. I figure that may be too small, since the charger that came with the device says 5V, 1A. Or is there anything that would prevent the device from charging with a non-HTC charger?

Charger provides 1000 mA, yet phone only takes 500.

Hi,
I bought a wall charger for my N1 today. I was searching for one with 1000 mA output so the phone would charge twice as fast, but after having it on for a long time and seeing that it was only 22% charged, I looked at the battery status and it said "USB". I unplugged it, plugged the stock adapter and it said "AC", and started to charge at the usual speed.
Is there a way to have wall chargers that are NOT the ones provided by HTC charge at a normal speed? thanks!
Interesting... it happens the same thing with an iPhone charger, which have the same output characteristics as the stock charger. I never thought looking at the battery status
FWIW, you can easily see if your phone is charging fast or slow by installing the quick system info app (AC=fast, USB=slow).
I'm using the 1000 mA charger with the USB to micro USB cable that came bundled with the phone. Might it be the cable limiting the power?
I've been trying to figure this out too...
I bought a USB car charger to charge my phone in the car whilst driving.
However even with my phone on standby it still loses power.... I don't know whether it's because I'm using the USB cable or the charger is inferior.
It is rated a 1000mA (the charger).
I bought the HTC car charger from expansys.. bit costly at around £20 for a charger but it works perfectly for me. Drove 4 hours with copilot running, and battery remained perfectly charged
As well as the stock charger, I often use a pikie USB charger with a Nokia micro USB cable... phone reports an AC charger in use.

Charging without Samsung AC Adapter?

I went out of town this week and made sure to grab my USB cable, but left the AC adapter at home figuring I'd just charge off my laptop via usb. Apparently not... I also tried plugging the USB cord into my iPhone AC/usb adapter with no luck. The only thing I've found is that when you turn off the Tab and connect to one of these devices, a green battery indicator will pop up showing that it is charging. Well, after about 16 hours, it made it from 15% all the way up to 48%. Does anyone know any way around turning it off to charge or why it is barely charging when it is off?

Well seeing as it has a 7000mAh battery, just about any run-of-the-mill USB charger isn't going to cut it. The amperage would have higher as well. Now i would hazard that an iPad charger (10 watts) would probably work just fine vs an iPod charger.
Your laptop's USB port isn't providing enough juice to charge fully. With the screen off it will only trickle charge and very slowly at that.
You'll need at least 5 Volt 2 Amp chargers.
You can also try this:

Or this:
http://cgi.ebay.com/190522553195?ru...ee-All-Categories&_fvi=1&_rdc=1#ht_3085wt_905
I've ordered both last week but neither have arrived yet. I'll report back.
You need a 5vdc supply that will provide 2A. 10W, not 5w as the previous post said. That adapter on ebay won't help the charge, it just disconnects the data line so it does not change its mode when connected to a computer. There are a lot of power supplies that will work and even more that won't, just made sure it supplies 2a. If you want to charge off your laptop then you will want a Y adapter similar to what is on usb powered hard drives but even then you will need to use 2 usb 2.0 or 3.0 ports and will provably only get 1a out.

S4 will not charge with AC charger; only USB

Last night I was charging my S4 in my car adapter, but noticed the cattery was still going down. I went home and plugged it into my AC (wall charger) and went to bed. The next morning the S4 was dead and couldn't charge. The only solution was to plug it in my computer and went an hour for it to get some charge back.
I have a root i337m running rootbox 4.1, and I went into TWRP to wiped the phone and installed the ROM again - no luck.
Is this a battery issue, a software issue or a whole device issue? Thanks.

I don't think its a rom issue. I tried charging via USB as well and had phone charging a few hours and it ate crap. So I only charge via AC outlet only. USB charges but at a very slow pace.

I made an error in the OP - I meant to say I left it to charge on the wall and I got nothing.
Right now, the charge light doesn't even come on if I plug it with AC.

Maybe see the results by changing the charger you're using?

I've tried 3-4 different chargers and cables, same issue. Charges slowly through PC,doesn't charge at all with AC. Did a factory reset after reverting to stock FW, no luck.

I doubt it's a ROM issue, but there's no harm in reverting back to stock to see the results (assuming you've backed it up). If it all fails, i think you should unroot and send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so it may be the best option to let Samsung handle it.
I had similar problems with my Note 2 before and now with my S4. What I found was, sometimes the usb cable wasn't tightly plugged into the wall charger. Once I've made sure of this, I've been able to charge (AC) every time.
I found this article that indicates that the S4 is looking for special sauce on the D+D- pins.
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/2
Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.
However I do not believe this to be 100% true. I think not all chargers will work..
I took a charger that is very vanilla (Wall charger but the D+D- pins are NC) and it works with the S3 and NEXUS7 but does not work with the S4.
This charger uses a stock USB cable so I took a wall charger that had gone bad but had a dedicated cable and hacked off the end and wired up my own cable...
That works! So it appears that the S4 will only charge properly with certain chargers that do something to the D+D- pins (either shorting them with a resistor like the article indicates
I then took a look at the cable I used to replace. It is a Motorola cable and it has the ID pin pulled high built into the cable... So I suspect that is required for the phone to work... But to fast charge it will need the special sauce indicated above!
Had the same issue and found the solutions which worked for me. Go into the developer mode and deactivate the usb debug mode.
Had the exact same issue. I took a soldering iron to my charging port on my phone. Problem solved. The ID pin had a bad joint.

I have a strange issue, my s4 is detected by pc, charges normally with usb ( wall or pc charge ) my battery is full but when I take the cable from microUSB port and s4 should work with the battery, turns off and consumes no battery, it's like refusing to use the battery and that it is full! battery checked on a sph l 720
I've tried installing other roms with safestrap but I still have the same problem, refuses to consume battery and while the battery is at 100% ,my s4 shows 0% if I disconnect the usb cable... game over. However, I can be on the safestrap menu for hours only with the battery, no problem, is a problem of rom I think but did not know how to fix it .. : (
I'm having the same issue as the original poster. The USB port is good, charges fine when connected to PC (although much slower because of different mVS). Have tried amidst everything and nothing fixes it. I've turned debugging mode off and back on, restore to backup, complete wipe and reinstall of 2 ROMs with and without apps, fix permissions, different kernels, different USB cables... The adaptor is in good condition. But when plugged in while on my phone doesn't recognize that's it's connected. Previously out would give a false charging reading. If off sometimes I got the grey bar battery but note is just vibrating every few seconds. Idk what to do...

I'd guess it's the charger. Get a new one

I had the same problem. S4 will recognize charger as USB charger, not AC. solution was to clean usb port connector, was some cloth covering wires. then restarted and worked ok
I am having trouble charging the phone the same way. I have reset the phone 3 times and still can't get a charge.

Phone says it is charging but it is not actually charging

Last night I charged my phone with the standard charging cable and the phone said it was charging. This morning I woke up and it had not charged at all. It still says it is charging but no power is going to the device. Any thoughts on how to fix this? Thanks!
Edit: Wireless charging is also not working.
I would try to charge the phone with another micro-usb cable without changing the stock 1.8Amps charger. It's very common for those cables to get damaged after some time of usage and not deliver enough current for the phone to charge.
That did not seem to do anything. The fact that wireless charging also isn't working has me worried.
