Galaxy S6 slow charging issue - Galaxy S6 Q&A, Help & Troubleshooting

Hi,
couple of weeks ago, my phone starts charging slowly. Whenever I use any other charger, than original, its charges only with arround 400-700mAh - thats only 1/3 of the charging speed. The non original chargers have 2A output: Samsung car charger, ASUS tablet charger, ADATA powerbank. I tried different cables, restared the phone, charging while phone was off, cleaning the phone conector with contact spray.
The battery consumption is normal, arround 50mAh. The fast charging with original charger works OK. All the chargers, I mentoined, worked perfectly just month ago. Unfortunately, I do not have the options test the chargers on other phones, because all other are just slow chargers (1A)...
Any idea, why this is happening?

partialy solved
I perform some tasks, and it seems, that it helps:
I did: wipe system cache. This increases the charging speed from 1/4 to 3/4 (400mAh -> 1300mAh) from the powerbank. The charging speed from car charger didnt changes
Then I did factory reset of the phone and it seems, that this helps.
The charging speed is very depending on the proper usb cable used. One cable works fino on one charger, but performs bad on another...

all USB Cables have different amperes, some have 2A some have 2.1A, furthermore, it also depends on the power source, the car's charger couldn't be as strong as the wall socket i think.
Anyways, on a side note, i suggest you try Aukey quick charge 2.0 powerbank. fast charges your S6.

I am wondering if this may be related to an update? Both me and the wife started experiencing this same problem, at the same time (different chargers). A few nights ago our chargers were working fine then the next night after 12 hours of charging battery is only around 80%
I did a factory reset on mine on Sunday for other reasons but this has made no difference to the charging issue

I tried this app as you suggest and to be honest my battery is worse rather than better. From fully charged, my battery has dropped by 20% in less than 2 hours pretty much being on standby. See screenshots below.

It's weird, anyway download the latest stock firmware for your device model and flash it using Odin. Wipe everything from Recovery Mode before and after flashing.

What difference would flashing stock firmware make? My phone is up to date and I did a factory reset on Sunday

I have the same situation, my s6is chargind just at 400mA speed, and my pc is showing USB not recognized (windows 10), thought it could be a usb charging board just pluged in new one, nothing changed... the same problem. there is somthing more, likely usb chip on motherboard or maybe battery... or some kind of problems

my culprit was the provided samsung cable. if you're in the UK the "betron" reinforced cables from Amazon sorted my problem... cheap and comes with warranty. Mine is still going strong and no problems here

For my case, it happened after my phone is updated. I brought my phone to a service center unfortunately it's already out of warranty. They are asking around $90 to have my phone fixed. According to them, they need to replace the battery and the sub board.
Im really dumbfounded how this happened.

I have the same problem with my s6 I have replaced the charger port and still won't connect to the pc or fast charge

[Q] My TF101 wont charge but it connects to the computer

Well I let it drain all the way one day by accident. Then when I tried to charge it with the stock cable and a non-stock brick it would take hours for it to charge fully. Also it did not charge while it was on and being used. It would have to be turned off for it to charge. So I quit on it and left it in the dust for 3 months. I then bought a new cable thinking that the cable was the problem (it was a 3.0 USB cable). it was also a fail. It charges slower than before. I dont know what the problem is. While it was on 3% battery I did a factory reset thinking that would fix it. It completed and still nothing. is it broken? Or am I doing something wrong?
help me please!

Turn it off. Connect to your PC's USB port for 6-8 hours. Put the ASUS charger in the fridge for 30 mins while pc charging. Then allow charger to warm up to room temp and plug into TF101 and it should charge.

Thats not the problem. I have multiple back up chargers. I have two Samsung GS3 chager bricks. They charge perfectly. The cable is brand new. The tablet just wont charge quick after 3 months of battery being drained. IDK what to do... :crying:
I was told there is a switch on or near the battery for this problem, don't quote me on it, I am just repeating what I was told and have not tried it myself but if you have nothing left to try, it might be worth checking

I had the exact same problem, was hard to solve but it ended up not being tbr charger cable but the charger brick. Using a different brick for the tf doesn't work,. I bought this http://www.amazon.co.uk/gp/aw/d/B0081PVGZE/ref=mp_s_a_1?qid=1352114943&sr=8-1&pi=SL75
and never looked back, charges very quick as well.
Hope this helped.

It seems A LOT of people have this problem with their charger on the Asus tablets. The problem is the power brick not supplying the required 15V to charge the tablet. It still supplies the usual 5V which makes it charge very slowly and ONLY when the screen is off or the whole device is turned off.
Anyway... either buy yourself another charger (those cheap ones on Ebay for $11 will do the trick) or make your own from a spare 12V power supply you got laying around the house and female USB cable end (like I did!).

[ KatKiss-KitKat #019 ]Battery not charging?

Hello.
Yesterday I upgraded from KatKiss #018 to #019. Up to now #018 had worked perfectly, but today with #019 I noticed that when plugging in my charger (I don't have the dock), I didn't get the little 'flash' sign on the battery notification; going into the settings to look at battery usage, I noticed that i said 'Battery not charging' even though I had left the charger plugged in.
I unplugged the charger, turned off the tablet, and replugged the charger, and the tablet turned on, which it does when plugging in the charger and being off.
Has anybody had this problem? Is it really charging but not notifying it? If not, what can I do besides reflashing?
Thanks!
me too

No problems for me and most people I guess otherwise they would stay away from the rom if it was not charging
Try to power off completely your tablet, then cold boot.
Try to change cable, try to test with another charger.
If that doesn't help do a full wipe and a clean install and test again before reinstalling anything else on your tablet.
if that still doesn't help, follow the procedure to report an issue in my signature, I'm not psychic.
Hello.
I have a problem related to the battery as well. Ever since I flashed to #19, my tablet and dock battery seem to run dry very quickly in sleep mode. I have come home from work to occasionally find the tablet unable to boot (it had a dock charge of no greater than 75% and a tablet charge of 100%) and when I plug the charger into the dock and then boot it, I find both batteries have next to no charge.
This is only on timduru's KK#19. I never saw this problem on #18 and below, or any of the previous 'droid versions (4.3.1_029 or 4.2.2_226).
I am currently letting the tablet's battery run to empty and then I will be charging the dock and tablet separately, but this is the first time I've ever encountered this problem.
okay

Did you try another ROM? I'm on #20 and I think I have (mentionable) more battery life. Not charging issues. Guess the fresh installment / wipe helped or an energy eater didn't survive the reinstall. Also I could observe two things (which I don't know of if they are related): Sometimes when the tab was docked it didn't charge. Second the the tab hat a battery problem. When docked and in sleep -> Dock empty next morning. I controlled this with Juice defender but weren't able to locate the problem in an app. This is now gone.
From my experience: I bought 2 power cable for the TF101 (only cable). One works as USB cable with no loading feature (not on USB 3.0 nor on the wallcharger). The other one works as USB connection cable and as wall charger. I can extend the original cable with USB to USB cable to transfer data and charge. I can't get any of that both two (CHEAP) cables to load extended or trasfer data. The two cables I bought at ebay were diffrent vendors. One for ~2,50€ the other for ~4€. If I remember right the original cable where much much more. What I want to say: There are huge diffrences in USB cables. Dunno. It would be a strange accident that the charger or cable broke when / while you intalled a ROM. Could it be that the "intelligent" battery stats are broken somehow? So they think the battery is full and therefor not charge? Or would the icon / indicator then show 100%? Does the icon get its information from the same source (or directly from) as the android battery management?
(ps: 12 hours for 35%=! ROFL!?? What charger is that?)

if it takes that much time even when it's off, it means that it's only charging at 5V.
Also at 5V it won't charge unless the screen is off if I remember well.
There's a special pin/connection made in the cable for the charger to detect that it's a Transformer plugged that will make it charge at 12+V
There's most likely a pin/ contact broken either in your cable / charger /tab, that prevents it to charge at high voltage.

So you say you go with option #3 then because u already did option 2, right? Quote Tim on option 2: "Try to change cable, try to test with another charger.".
So you have 2 x THIS and 2 x THIS? Because that would mean, what Tim suggested I guess. As far as I know this is the only way ASUS shipps the original TF101.
I'm asking because most people that I know would buy another noname charger or even just a noname cable instead of horribly expensive original pieces. If you really got the 2 x 2 pieces shown above,
then I'd guess wether your tablet is broken or the software on it is broken. But again: Did the charging problem REALLY firstly appeared when intalled the ROM? Or did you install the ROM because of the
fault? Or don't you exactly know.
To point out again: It would be a strange coincidence, that both cables AND adapters would stop working exacly at the same time when u installed #19. If you use 2 different cables at the same adapter: Then it's possible that the adapter is broken and only gives the USB (5V) loading speed. If you use 2 adapters and 2 cables and tryed all combinations: The most likely something with the tab isn't cool. The software or the hardware...

I have loaded #29, and I started seeing this issue immediately. It was fine before that. After loading the ROM, it would only charge when TF is dead. I have the original charger and cable that came with it which was working fine before the upgrade. So, I don't suspect either of them.

I was going with #29 and #30. Havent seen or heard about any loading issues but that was related to loading the tab on an USB port ... What actually is an bad idea even on USB3.0.

[Q] Charging Too Slow Now

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

Stock charger - charges slow and drops battery

Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

Get in touch with the retailer you got it from and ask for them to provide you with a proper charger, as a compensation

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.

USB port damaged?

I have looked around on this topic before posting, but nothing applies to what im experiencing
Up until this morning, I haven't had a single issue with my USB port or charging in general.
I clean flashed Purity KitKat, flashed compatible Uber kernel and installed my apps as one usually do, and let the phone charge for a while. A few hours later, I realized my battery was at 0%. I started panicking, looking for a USB replacement part, which I found for about $12 on Amazon. I decided I would download GSAM battery monitor to see if there was an issue with my charging cable.
What I saw was the mA flow was acting erratic, sometimes shooting from -700ma (yes, that's negative 700) all the way up to 1800mA. Even by just rotating the screen, it would drop instantly. . The phone charges, but a little at a time. I disabled KSM and fast charge which seemed to have a positive effect.
I'm not sure what caused this, or how to fix it, but I've attached a couple pictures to give you an idea of what I'm seeing. If it is in fact the USB port, would using a Qi charger be a good option or should I just go ahead and dismantle the phone and replace the USB port?
Note: windows still recognizes the phone and I can send files from the computer, and the charging bolt is showing.
Have you replaced the cable? Far more common for the cable to crap out then the port. Cheap or broken cables will appear to work, computer will detect phone and even display a charging indicator but it won't actually charge. Had happened to me in the past.

Yeah I've tried numerous chargers including my car charger. They all charge, but it took 12 hrs from 0 to 100

Try flashing the stock rom to rule that variable out. If you want to be sure that is the usb port you could try with a wireless charger as it could also be the battery, you can find a new one at the same price range of the port.
It does seems a lot like what happened when both the stock charger and the cable were damaged. I tried to charge the phone and when disconnected it had less charge.
