Galaxy S5 Quit Taking a Charge - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

I'm trying to troubleshoot what might by wrong with my S5. I woke up the other morning and my phone was completely dead. It was plugged in, but no LED was on and the phone was not responding.
I've tried he various troubleshooting that I've seen around the internetz, such as:
removing the battery / discharging with power for 1 minute...plug back in and try again
use a different charger / cable
clean out the charging port (I used my air compressor to blow out any dust that might be in there)
I feel like I've exhausted all I know how to do. I do have another S5 coming in a couple of days, so I'm hoping to use that to see if it's either:
a problem with the battery
a problem with the charging port
something else?
My guess is that if the new battery comes in and I put it in my old phone, that will help me tell if it's the charging port or not, correct? My assumption is that if everything else is fine, then my old phone should power on.
I am a little nervous that it's something else though; I measured the voltage out of my battery and it was registering nothing the other day. When I plugged it into the phone and allowed it to charge (even though there was no indicator and the phone would not turn on) I measured the voltage again and it was registering ~2.8V.
Anyway, thanks in advance for anyone here that can offer any other guidance as to what I can look into to troubleshoot what the problem might be.

I've verified that another battery allows my phone to boot, so my guess is that it's the charging port.
How hairy are these to swap out? Is it a realistic repair?

ive cracked an S5 apart, and getting to the charge port isnt so bad if you can get the back plastic cover off, but you might have to remove the screen too. The S5 is waaaay harder to get apart than the early notes

You can get a wireless charging receiver or an external battery charger to charge you battery instead. I charge mine wireless as much as possible to help save the charging port for when I actually need it.

Dead Tornado

So.. here goes my problem..
Got my Qtek 8310 three days ago, and the very same day I got it, decided to upgrade from WM5 to WM6. However, the battery charge meter gave me wrong info about the battery charge percentage, and the phone battery died just after I formatted the BINFS and re-setted the device in TeraTerm.
The device still powered on, after each USB cable re-insert, but died, after 5-10 seconds. After a couple of attempts, the phone didn't turn on at all.
Did some info search on the web and found out, that my battery fell to an critical voltage level. Li-Ion batteries require a certain voltage to even be able to accept a charge.
As I got an non-original battery (Sanyo ST26C) I suppose it is poorly designed and doesn't have good under-voltage protection (I have read about other HTC models (e.g. Wizard) having this problem as well), so the battery dropped below these limits and phone now identifies the battery faulty and doesn't let it charge. This is for consumer safety, because attempting to charge damaged Li-Ion cells can be dangerous, as Lithium is known to be able to catch fire/explode.
So the phone doesn't let to charge the battery in any way (1amp wall charger or USB cable).
Anyways, I tried to jump start the battery (charge with bare wires) to give it initial charge and... it worked. However, there goes my main problem: As soon as I insert the battery which has the initial charge, the phone starts immediately and boots to a bootloader (as there is no OS, formatted BINFS) and the the phone does not charge while in bootloader.
Then, I tried to turn off the phone: Hold down power off button for 5 seconds - phone turned off. But as soon, as I release the button, red light flashes once (as it does everytime, when you try to turn on the phone, it's normal) and then orange LED comes for a second, indicating a charge (as the battery is no longer considered faulty - phone lets it to charge), BUT then phone starts again to the bootloader and it somehow prevents further charge.
So: as soon as I release the power off button, after the phone has shutdown, it starts again, everytime, and soon the battery dies again.
My own thoughts of solving this:
* Get a fully charged battery from a friend, install the windows on the phone, and then charge my own battery (I know noone, who may have HTC Tornado, will be hard to get);
* Buy some standalone dock charger, which can charge batteries directly and charge the battery happily (haven't seen any around yet, so will be really pain in the arse, to get one);
* Charge battery with bare wires for an extended period of time, to give it enough juice to install windows (which I strongly doubt, as battery damage could occur);
Any other ideas? Ideas and comments, from people who know, or had similar experience is more than welcome. Looking forward for answers
Its funny. Reading you I've realized what people tell me about "I make a question and I answer it myself" So... You have the answers my friend. For options 1 and 2, use E-Bay. As a matter of fact, there is an aftermarket charger in ebay that charges your phone and a spare battery and it includes the spare battery when you buy the charger. I believe it runs for under $20.00. For option 3 use some wood cloth pins(those used to hang cloth to dry). I would say with at least 2hrs charge you should get a good 50% charge on your battery, enough to flash your phone.
Edit: Here is an Ebay Search. But, keep searching till you find the one that includes the extra battery. Chances are your battery is no good or won't last you very long.
Good Luck!
Get a new battery man, these li ion batteries, are no joke, especially the fact that they are made in China/Taiwan, I myself had used a tornado battery even till the days when the battery has bloated and cracked the back cover, when a single charge could not even last 4 hours.
Those days, were like having a timebomb in your pocket, ended up I got mysel a new tornado at a price cheaper than a replacement battery.

Well yes, I have some suggestions, but I am also expecting others to have some, too. And by sharing the knowledge, maybe I could prevent myself to spend more money on this issue

The main problem with e-bay is... my country. at least 80% of the items, don't ship to my location.

Thanks for the suggestion. The main reason why I am in serious doubt about this option, is that standard chargers usually have some sort of regulators and monitors the charge, prevents from overcharging, etc. But on the other side, USB charge output is only 100 mA, so it couldn't be that bad if you think about it

Well, the fact, that it is manufactured in China actually says nothing Many companies choose China to manufacture their products because of low costs. And the most of electronics is manufactured in China and other Asian countries.
Anyway, before getting myself an new battery, I would like to try resurrect this one If this won't last long for me - no problem, I will get an new one. But until I'm convinced enough, it's a waste of money, which I don't like doing
And one more thing.. maybe someone knows a way to keep the phone power off?
Because as I said earlier on, it's charging only when it's turned off, and not in the bootloader. And problem is that, as soon as I put the battery, it starts-up the bootloader.
Get a desktop charger perhaps?
Or if you are adventurous enough, mod the USB cable, and charge the battery directly, only if you know what you're doing, and only if it works

Well.. thanks for the answer, but we've already discussed this option and now I am asking whether or not, someone knows a way to turn off the phone and keep it turned off (prevent from self startup) while the phone has no OS (got formatted BINFS).

I've already done that, and yes, it works. But I need someone to confirm, if it is safe enough to charge the battery for an hour or two.
Have anyone tried that?
I don't think that it's very safe. But I was having a similar problem, and I just left the phone connected to the power cable, and even though it seemed like it was not charging, it apparantly was.
Or you could just get a new battery. On expansys I saw a new one for ~$20.

Well..
With a modified USB cable (bare wires), which got power output of 100mA I have charged battery directly for approximately 3 minutes, and the phone turned on, and was operational for 4-5 minutes until the battery died again.
And before that, I've tried leaving it on an mains charger, which got power output of 1A (1000mA, 10 times USB). I left it for a hour or two, although no led was showing up to indicate a charge. The phone didn't event turn on after this 2 hour "charge".
And the reason for this is explained in my first post. Will try to leave it charge over a night, though, expecting for a miracle

But new batteries usually come empty, so it's no use to me. I have also explained why, on my previous posts.
So before buying an cradle charger, I would like to find out if these budget-friendly solutions will work:
1) Find out how to keep the phone powered down (because it's the only moment, when it truly charges);
2) Find out if it is safe enough to charge battery with bare wires for extended period of time (1-2 hours);
Just came up with another idea. Searched the forums and found a very similar problem to mine:
fritzgerald said:
For some odd reason my wizard likes to say the battery is full when its actually dead and that it's dead when it's really full. Well a few days ago I was reflashing to try and take care of the issue and it died during the middle of flashing. It would only goto the bootloader screen and would not charge. Well I decided I'd post a few pictures of my recovery technique utilizing my wife's phone. Cat5 cable striped at the end and twisted to each of the positive and negative battery terminals and the Blackberry's battery put it so I could use it to power the wizard.

So.. I've got a Sony Ericsson w810i, would this technique work? The w810's battery is Li-Polymer, 900mAh 3.6V (although some sources say, that this exact battery is 3.7V..), compared to Li-Ion 1150mAh 3.7V Tornado's battery.
Voltage seems suitable..
Haven't got any answers to my previous posts, so I tried.
The trick worked, Sony ericsson's battery can feed HTC Tornado perfectly. However... got another problem..
Here's how I wired it up. The positive wire takes two contacts and the negative takes another two aswell. The ends of the wires are then connected to the sony ericsson's battery. Phone starts, and boots to a bootloader. Everything's seem to be perfect.
Then I plug in the USB cable into the computer, the other end to the phone. Phone recognizes the cable and puts label "USB" at the bottom of the screen.
However, there's something wrong with the connection.. TeraTerm fails to connect and Update ROM utility fails, too, with an "cannot connect" error..
After that, I have tried using the original battery, with no wires attached, just plugged it in (gave it an initial charge again) and the USB worked without any problems: TeraTerm can connect.
So the problem seems to be in wiring.
I have tried to connect the wires in different random ways (crazy, I know), but only one alternate way did worked. Although, phone did heat-up rapidly at the area, where it says "HTC Innovation" and phone's display showed "USB" even if no USB cable was connected.
So.. looking forward to some thoughts or any knowledge, of why is this happening, wiring schemes, or any other suggestions..
FINALLY! SUCCESS!! I've connected the wires from the sony ericsson's battery to touch only one pin on the phone, instead of two, as shown in the picture. The phone didn't turn on, as I've tried this before.
But then remembered that the same pins charge the original battery, so inserted the battery and VOILA! Phone turned on to the bootloader and the USB circuit wasn't blocked no more! Flashed the phone to WM6.5 now successfully and the original battery is charging, as I write this post )
So, if anyone got HTC smartphone dead, while flashing, let me know, will try to help you out, since I've walked through this hell myself
Thanks goes to karhoe, for an excellent guide for flashing, also dharvey4651 for an excellent guide on installing vista's USB drivers (got new PC, upgraded to vista) and last, but not least - the whole XDA-developers community for helping me out
1A Wall Charger Works!!
I've had the same problem discussed above. I was trying some of my own 6.5 ROMs, which by the way were getting stuck at the initial boot screen itself. Due to some unavoidable reasons and circumstances, the phone freely was left to itself at this exact state, untethered to any power source, for extended periods of time, during which it slept and refused to wake up again, all my pleadings going in vain. And when it did boot, it went into the tricolor screen conveniently and switched off in ten seconds. I turned to the net for help and found that any charger with rating above 1A would help in giving it the required juice. I didn't want to waste any of the 6 USB cables I have.
I got the original charger, which is an 1A charger, after 2-3 hours of searching my room (Hey, Don't be too hard on me! In the end, I got it, right? Actually, I use the PC for charging, and a smaller 550mA one sometimes-- both didn't work this time) and then, when I connected it showed the screen again. But this time, I found that it was capable of running it without the battery being present.
So, all I did was I kept the charger connected to it with the phone switched on in the tricolor mode and with the battery inside. After half an hour, I tethered it to the PC and flashed a proper ROM. And Voila!!! IT WORKED!! It was 2.45 in the morning!!
I guess the power from the 1A charger is enough for the phone to run and charge it too which is not the case in the 550mA one and the USB cable.

Glad to hear that it worked for you Unfortunately, it didn't for me (as I only have an after-market charget, not the OEM one, although it is 1A), so I had to search for alternative methods.

[Q] Charging oddities while phone is off

Hi,
Last year my girlfriend allowed me to root her Sensation to try out different ROMs and all went well. A few months ago however, she started to have problems while charging her phone.
If she plugs it in while the phone is closed, the orange LED flashes on/off at around a 2 second interval, instead of holding it's colour. Furthermore, it never changes to green to indicate that the charge is complete. When the phone is in this state, she can't turn her phone on either - she has to unplug it in order to turn it on. If the phone is already on, and she plugs it in, everything behaves normally.
Either than that, the battery seems to hold the charge normally and the rest of the phone still works very well.
I've tried searching for similar problems but haven't landed on anything similar or which may be helpful. It's really got me stumped to what could be the cause, and more importantly, how to fix it!
Would someone have any ideas?
Thanks!
Does the phone behaves in same manner if it's fully charge n switched off when plugged to the charger.does the orange led fluctuate.
The orange led fluctuate whn the voltage of charger is less and it takes times to charge try switching the charger means if you use wall charger then charge through pc and vice versa
Hit thanks button if you find me helpfully
sent from amazing HTC sensation using xda premium
We tried switching from wall plug to USB on the laptop and it does the same thing. However, we noticed that if the battery isn't completely drained, the led doesn't flash - it charges normally.
Would there be a way around this?
I'd pick on the odds that the LED light hardware controller is slightly faulty, but if its really like you said its nothing to worry about, right?

Hi,
greetings
this used to happen with me when i was on stock rom.
the problem is when the battery is completely drained it needs lots of voltage to get charge
for this problem i took my cell to htc service center and they replaced the adapter and the problem was solved
i think you must buy a new adapter or say a new charger i thing that must solve your problem of led and your phone will get charge as normal even with the battery completely drained OR i think we get wall chargers you can look at the picture in which we have to place the battery and the battery gets charged you justt have to put the battery.. this charger is locally available in indian market for 80 to 100 rs.. you can search on net for the charger this is really a good thing and is a universal charger chagers each and every battery here in india we call it as khekda (marathi word for carb ) charger
let me know if it does solve your battery

[Q] Nexus 5 charging only when it is turned off

Hey there!
My Nexus 5, after updating it to 4.4.3, is having a issue: the device is charging only when it is turned off. When I turn the phone on, while charging, it will remain charging. But if I connect the charger, when the phone is already turned on, it will not charge.
I have tested 2 different cables, same issue.
Is anyone else having the same problem? How to fix it?
Any help would be appreciated. Thanks!
Just for clarification: I'm using Kit Kat 4.4.3, rooted, Xposed.
what are you charging from? ac or pc?
AC!

Another question, are you using the stock wall wart? Some aftermarket chargers don't put out enough amperage. Another possibility is that you've got some rogue processes keeping your phone awake so it's using battery as quickly (or quicker) than it can take in a charge.
I'm using the AC charger that came with my Nexus 5.
Updated to 4.4.4. Problem not solved.
I think it might be a hardware issue. I have the same problem with my pebble. I have tried multiple cables/chargers and it only charges when it's off. When it's on I get the charging notification but it doesn't actually charge
Nothing. The devide is still charging only when it is turned off.
Having the same issue since update 2 weeks ago. Already wiped phone and problem still exist. Start to think it's hardware but tried 2 different charger same issue.
So guys I am almost the same problem since this morning. I went on a 3 day trip to the Netherlands on Friday and charged my phone in the car for the last time on friday. I died on me this morning. While I was on the way back today and my N5 was in it's last percents of battery I noticed it wouldnt charge anymore. I thought fastcharging might have killed my car radio. Now back home I tried to charge it. For some reason the charging while off screen reapeared as soon as it turned off. Whenn I turned it on again it stopped charging. Tried rebooting multiple times. My phone now only charges while being in Fastboot or Recovery mode. Anybody having any ideas what might have caused this an how to fix this? Cleaning the charger didn't help me.

Hi. Also had this problem a few days now. Alot of headscraching is done
N5 won`t charge when on. Tried my N10 charger, but still the same. With my wireless charger it register the phone when off, but cannot charge it at all. I've also done a factory reset, and even changed the battery. Still no solution. Wondering if the charging port is damaged somehow. It doesn't cost much so maybe I`ll order a new and replace it to. I remember draining the battery more than usual right before this issue acurred. I was hiking, and din`t bring my portable charger. Also it could be some kind of water damage. Had the phone in my pocket all the time, it was not raining, but I got pretty sweaty:-9 Never had any issue with my stock Nexus 5 up till now. Don`t think this i a common problem, when this is the only place I've found others with this issue I`ll order the charging port, keep on searching on forums, and take it from there.
Good luck
I'm having the same problem on my Nexus 5 now as well. When on, it won't charge via micro-usb (via original charger or USB-to-PC), nor will it charge wirelessly. When turned completely off, it charges, but at GREATLY GREATLY reduced speed. It seems to be stuck in a loop as it it's just been plugged in. It cycles continuously through the lightning-bolt battery image, followed by the charge percentage graphic. The screen blinks, then it starts again. I suspect that it only charges for a moment or two before each reset. For example, it only charged about 20% over the span of six hours last night.
I've tried four chargers and four USB cables, and of course both wireless and wired charging. It's something with the hardware I suspect.
Anyone have any suggestions? It looks the the factory wipe upthread didn't help...
Charging spare part
I am having same problem too. I'm guessing it's because of water damage. Where did you find the charging part? I'm thinking of ordering one for myself to see if the problem is fixed!

[Q] Tablet doesn't charge, dock does - what to replace?

I've been enjoying my TF300 since the month it was released, but in the past few months the battery stats have become less and less accurate. I was watching YouTube videos on it while it was docked and charging yesterday when it suddenly died, and I haven't been able to get it to boot since. Sometimes it will start to boot, but die half way through the boot animation, which implies that the battery isn't charging.
When I plug the charger directly into the tablet, it flashes orange twice and then does nothing. When I plug the charger into the dock, that shows green - so I assume the dock is fully charged. When I plug the tablet into the dock, it flashes red twice again.
The logical assumption from this is that my TF300 has stopped accepting or holding a charge. My question is, which part do you think I should try and replace first? I understand that the dock connector has separate pins for 5V and 15V charging, so maybe that's been bent or broken somehow...or the battery itself could be worn out...or the motherboard could have developed a fault. Has anyone had a similar experience to this? I don't want to buy a new tablet as there is absolutely nothing wrong with my beloved Transformer other than this!
I'm going to leave it plugged directly into a standard PC USB port for several hours tomorrow while i'm at work, to see if it will trickle charge that way. That would imply the charger is at fault, despite the green light from the dock when it's plugged in.
sort of same here
My thoughts are that the one battery is no longer seen by the tablet and the other is getting too much of a workout as a result.
We have possibly just lasted beyond it's expected lifetime - which is kind of dissappointing. I don't understand exactly, but we might troubleshoot this still.What rom or Firmware are you using? I am on straight CM11 with no other modifications. I am using the tablet docked al th time and th rom "sees" the two batteries but dies at about 50% of the one without touching the other. I'm pretty sure that it really only is using the dock battery and never seems to go to the tablet battery anymore. Wish I could fix it - will try to use it without the dock and see what happens.
It was running KatKiss 5.0.0 - I kept reminding myself to go and download the latest update but never got around to it.
After leaving it plugged into a standard 800mA charger all night and all day, it booted for about 20 seconds and then died again before it reached the lockscreen. It seems that the battery is either charging unusably slowly or not at all. I may have to start hunting for a new convertible!

Well mine is working fine disconnected from the dock - so it sees the Tablet battery and uses it now; I will use it until it needs charging and then try again - by attaching the dock and charging etc. Will yours work if just plugged in? - like a laptop with an old battery, does it still work but you are tied now to the power supply / charging cable? I have installed the latest "homebrew" Omni now to just get a new start on things and will continue to just use up the battery and see what happens next. My preference is to have vanilla CM but it seems the tablet battery was invisible. I hope by re-setting things and having a new Rom in place will give me a clean slate.
Sadly no, it doesn't run even when permanently tethered to the power supply. I think the battery has to report a minimum state of charge before it's allowed to turn on, and that's where it's failing in my case.
Batteries are back
I wish that I could tell you how - but I can't - the batteries are back to full functionality. I will tell what I have done and this might possibly help. I installed Omnirom with Lollipop and it worked but was very slow. Then I installed CM 11 back (then CM 12, then CM 11 again all with the appropriate GApps & SuperSU etc.) and it seemed to put things back in order. I did also install a battery calibration app which just deleted a file tracking the battery(s). Some where in there the batteries starting working properly - this involved more than a few re-boots and re-installs (dirty and clean). In all this mess lies a possible solution or maybe it was when I slammed it shut in frustration - this could all be due to a loose wire/solder joint too. The battery is following the "normal" process now of first draining the tablet battery to ~ 80-90%, switching out to the dock battery, then switching back to the tablet when the dock is drained fully.
@kjwaugh
I can't recharge my battery and I have CM-11-20150112.
My little led never turn on orange light.
My question for you is: Does your led turn on when you plug in the USB cable ?
I'm afraid I have broken some analog circuit inside the tablet or, I hope, only the cable.
Please let me know.

This was also happening to mine and I cleaned the charging port with a qtip and alcohol. I flattened the qtip first so it would fit up inside, just be careful that the tip does not have loose cotton. Hth
I had similar issues and also my HTC USBC headphones stopped working. I ordered a new charging port and did it myself. It wasn't too bad. hardest part was taking the back off.
HOWEVER. I have a new issue after the phone worked fine for months after doing that. I recently got a message onscreen that the charging is causing a problem and to disconnect the charger immediately. So I do. Mind you this is the same chargers I've been using for 2 years. Now, the phone WILL NOT charge with ANY charger while it has battery. Once the battery dies, it will charge back up to 100%. This has happened 3x in a row over the past 3 days. Has anyone ever experienced this?
I should say, one of the chargers I got new and it went into the USB C port a little funny. If you've ever used different chargers you might know what I mean. However, it supported quick charge and worked months before one of my other main chargers stopped working, and then a few weeks later I got the above message. Anyone have this happen to them?

That's scary, do you think it could be the replacement charging port failing again?
I tried to clean it with alcohol, seems better at first but then back to the same. I read somewhere to use a business card to try to take out any lint/dirt whatever, I did take out some dirt, but then now the charging port can't hold the cable tight, it's kind of loose. I ordered a charging port and a battery (looks like easy swap once the back is open), wish me luck.

Dont forget to ground yourself before disassembly, I learned the hardway. Also it helps to use a hair dryer to soften the glue that holds the back and battery in place!! Hth

OK, so the charging port managed to come Sat morning before I had to take off for an overnight trip. In anticipation of that, I began taking off the back before the charging port arrived. It was really the hardest part of the whole fix, but I still managed to take it off in 15 or 20 mins... not too bad. Then the part came and the swap was pretty straightforward. It's charging properly now, yay!
I also ordered a battery (from a different seller though) and it is only coming today. So I didn't glue the back yet. The original battery was not terrible, but taking the chance to replace it.
OK, swapped out the battery as well, will have to see how good it is. Accubattery reports my original battery as around 1800mah.
