Plugged my phone into a 2.0 charger from either b my s4 mini or my n3 before going to bed, woke up and phone wasnt fully charged. Didn't think anything of it, just went on my way. Now my phone just died completely went to use that same charger and didn't charge.
Downloaded a galaxy battery current charging app and it shows negative amperage when plugged into 2a charger. Also with the screen off it only shows one green dot instead of the trail leading to the battery.
Sounds like your 2 amp cable was defective. I've plugged mine into a 2 amp and it just takes a lot longer to charge
I thought so too, so I used the brand new cable that came with the n5, same result.
If the other cable was defective it could of damaged your usb port possibly. I use a 2 amp in my car sometimes then my 5 amp at home no ill effects
I use my note 3 charger every night because ive always heard a slower charge is better for battery longevity. I have had absolutely no problems and wake up with a full charge after a average 5 hour sleep every morning. I only use my note 5 charger for quick fill ups during the day. Im guessing your wall wart is bad. Try the 2amp cable on the note 5 charger then U will know its not the cable

Same, no problems with the 2 amp here.

This question has been asked before but no one can answer it odd.
Nexus 7 charger is two amps. Stock s3 charger is one amp.
Can I charge my s3 without damaging it using the other charger. People say it charges faster. Some people say it doesn't matter because the kernel will limit it.
Whats the real deal?

I am pretty sure it will use only what it needs. Atleast thats what i been taught at radioshack

There are a lot of variables as to what the maximum charge current will be. I've never seen it go over .8 amp. So if you use a 1 amp, or a 20 amp charger, it will be .8 amp. MAX. Usually less.
Use whatever you have handy that is 5 volts.
I actually use an old 5 volt .6 amp charger for overnight charging. A bit slow, but I don't care.
I have a home grown charger on my motorcycle that can go well over 1 amp, but the phone only has ever gone to about .8 amp. For a long time I had that charger set to 5.5 volts, and the current was up a bit closer to 1 amp. But the heat worried me and I bumped it back down to 5 volts.
Have been charging my s3 on the new iPad charger, and 2amp chargers bought from amazon without any issues.

I'm using a RCA dual usb charger one usb plug is 1 amp and the other is 2.1amp both charge fine but I don't notice the 2.1amp charging any faster. I so kinda point less to use in my eyes

You realize you're using a 10v charger on a 5v device right? That can toast your battery over time, a short time too depending on if you leave it plugged into it over night, etc..
Hi All,
Is anyone having issues with their non-nexus 4 chargers charging on and off? When I plug my phone into my car usb charger (5V/1A), the charging icon flashes on and off; I didn't want to ruin the phone so I unplugged it. I googled it and saw this thead; someone mentioned that the N4 required a 2A charger so I wanted to see the experience here.

The charger I'm using: http://www.amazon.com/Belkin-Micro-Auto-Charger-5VOLT/dp/B002F0200Q
Stock charger is 1200 ma.
My HTC car charger gives 1000 ma and works fine for my nexus 4.

I haven't had an issue with the charging going on and off, but I have been having an issue when I'm charging and using the phone with a non-LG charger. If I use the one that came with the phone, all is well... But if I use any other charger like my old one from HTC, the phone heats up real bad and I get horrible thermal throttling. I've tested it a few times, always doing the same thing (looking at XDA) and the LG charger is the only one that plays well with the phone while charging/using.

I just checked with another USB wall charger that I had which puts out only 500mA; that one works fine... so I guess my car charger is broken.
I've been using the charger that came with my nexus one and had no problems. The last couple days I've been charging off my PC because apparently slow charging is better for the battery.
Out of the blue I noticed my S3 was charging very slowly, it even was losing a charge while it was plugged in while I was using it. I figure it had something to do with my custom ROM so I reflash, still same outcome. The battery was still holding a good charge, so I figured it was something else. I then went out and bought a new charger, which came with a micro usb cord to see if that helped. Plugged in the new charger while using my old micro usb cord, still same outcome. Then used the new micro usb cord and old charger, charging went back to normal, problem solved! I would of never thought that the cord would malfunction from day to day use after such a short lifespan. Moral of the story, check your cords if you experience the same problem, it could save you some time and money!
I bought some cheap ones off Amazon. They won't charge the s3 but will my touchpad. But my s3 charger won't charge my touchpad. Stuff is weird at times.
Glad it was an easy fix.

Must have been charging in USB mode.

I believe it, using my old galaxy nexus cord for my s3 charges extremely slow (like 200 mAh) for some reason. I switched to a different cord and now it's all good, I have no clue why but that's how it is.

That's weird mine started doing the same thing just in the past few days. I have to unplug and plug it back in multiple times before it goes into AC mode

I really think that those cheap cables don't charge nearly as fast. Especially the Stock Sammy ones. I use the thicker LG cables and they seem to charge so much fast and transfer files faster..
I just went through the same thing. The phone was charging for twelve hours and only gained 50 percent. Took forever to figure out it was the cord.

USB Cable
I think charging AC is not fast charge.
You should to charge USB cable.
Thanks.

That's what my phone was doing, I'd unplug then plug it back in and would go from USB to AC, but it still charged slow. That cable, no matter what it said, would still charge slow as balls.

I had heard of "Buy Cheap, Buy Twice", but now we've got "Buy Cheap, Charge Twice"
A lot of times it's the DC power brick that makes the difference. Not all of them have the same power output. Rarely, if ever, is it the actual cord itself. USB cables use pretty thin gauge wire already and the only way you're going to get a difference from one cable to another would be if it was REALLY cheap and using an ultra-thin wire or if it was a REALLY long cable (increases in cable length equate to increased resistance to electrical transmission...)
All USB cables are 5 volts. However, there can be significant differences in the milliamp output for each DC adapter. Aside from being a computer geek and gamer who builds custom PC's, I happen to be a hotel General Manager. I just checked our catch-all box of phone chargers and found that while every charger has an output of 5v, the amperage put out varied from 350 mA to 1000 mA from one charger to the next.
This variance in output is why some chargers take so long as compared to others. I don't know what the actual Samsung charger output is, since my charger is at home, but my guess is it's between 800 and 1000 mA.
I use the stock BB charger to charge both my 9900 and GS3, the BB charges pretty normal but lately I've been having a problem with the charging time on my S3, I have to charge it everyday now, my usage isn't that heavy, it lasts me a day and a half normally. Going to start using the stock charger to see if there is a difference.
I'm using the Samsung stock charger after not having used it for a month and noticing that my battery levels have deteriorated after using my BB stock charger. The battery seems to be discharging while on the charger! I'm in for a world of pain, going to monitor it for a while. I could be stressing over nothing.
Hey Guys,
So I was recently on a trip this weekend and was using Navigation on my Nexus 5 for a 4 hour drive. I had noticed though after a short while that while I had my Nexus 5 plugged into a charger it was still continuing to drain battery.
With my Galaxy Nexus in the past I was able to run Navigation / Music / Etc.. all whilst still charging so it came as a disappointment when I saw this.
I made sure that I was charging on (AC) mode and it still continued to fall, albeit a little slower than (USB) mode though. When I went to the battery usage navigation had taken up about 59% of the battery drain, I was surprised because I though it would have been the screen but that was only like 14% of the battery drain.
Anyone else run into this issue?
Check the Amp output on the charger. Anything less than 1A will not charge the phone while in use.
I had the exact opposite issue with my G-Nex, the "rapid" charger I was using only output 550mAh as opposed to the 1A that is required to charge while in use. I don't believe it is an issue with the phone, it's probably just the charger. $10 to $20 will get you a nice, reliable one with the proper output, and possibly an additional USB port.
Hopefully this helps
Don't buy cheap car chargers, just not enough power. I use a Verizon car charger that has an extra USB port for charging another device and it charges while the device is in use.
Thanks for the input guys, unfortunately the charger was 1 amp that I was using. I do have another car charger that I use and none of them are the cheap USB ones. I guess I'll have to do some more testing with the other car charger that I have.
I was just mainly concerned, not if there was something wrong with the phone, but with the fact that even when charging in AC it wouldn't keep up with navigation's wear on the battery usage.
Thought I would update to confirm that my Galaxy Nexus car dock charger charged it extremely well after testing while navigating.
Definitely was the other one I was using.
When you switched chargers did you happen to also use a different cable? I couldn't get any of three different chargers that I tried to keep up with the GPS battery drain. Then I realized I was using the same cable with all 3 chargers. The problem was that the cable kept the phone in DC charging mode at nothing more than 0.5 amps. I bought this fast charging cable on Amazon and now I actually gain battery percentage even while using my GPS full time.

I had exactly the same thing with my old phone and discovered it was the cable not letting more than 380 ma pass through it.
There are apps like this https://play.google.com/store/apps/details?id=ccc71.bmw that let you monitor mah in and out etc so you can test out different leads and chargers

I tried laying a folded piece of paper in between my phone (caseless)and the charger and it worked as intended. I believe the magnetic field due to the phone being too close is too strong to maintain the intended current. Or vice versa. Using my case results in the opposite result. Not 100% sure, it's been 15 years since my electrical theory courses.
It works great for my wife and i and we have them both in different casses....
Mine wouldn't charge for more than a few minutes regardless of battery level. I tried it with a different cord/plug and it works fine. So my cord or plug is bad, but the charger is fine.
IT seems like it is the only problem with the wireless charging. I tried different 2AMP adapters and USB cords. I tried making sure the USB cord wasn't coiled and straight and vice versa. Tried the paper method, seemed ok but silly. I have a case coming soon. I put the Note 5 on 2 different QI chargers. Goes all the way up to 100. Its the charger/note 5 relationship. Not sure what it is. There are a couple other forums on them.
Experiment time....

This is way more picky on placement than my note 3 with the oem wireless back added.
Anyone else notice a relationship between wireless charging and notifications? It seems over night if I don't get any notifications, it charges no problem. However every time I wake up+ with a notification, the wireless charger is blinking, and my charge isn't full.

I got all my notifications last night no issues
I actually have been having problems, despite my optimistic previous post. I can't seem to get a bead on why, though. Problem seems worse with some of my electrical outlets than others. Turning on daydream seems to ensure a full charge, but then it doesn't turn off at 100% and gets warm. So, I dunno.
I took my Samsung circle piece of crap back doesn't seem to charge at a snails pace. Sprint rep ask "are you sure.you had it on there right?" Yea no no im not a damn idiot. Im ordering a qi stand hope it will at least charge overnight.
Right now only seeing good results on the Samsung wireless charging pad I have a duracell and it sounds to connect but no charge

I was at 2% when I placed the phone on the charger(free Samsung charger best buy gave) and it said it would be less then 2 hours for full charge
Having same issue phone starts to charge and when i get a text or email it quits charging have to completely remove from pad and put back on to start charging. Have not tried daydream option.. i unplugged it last night and used cord to charge.
I exchanged my charger and the new one has none of the issues I have been experiencing. Charges fully every time. No fiddling necessary. I should have done or sooner.
I will try different outlet but if it keeps up going to try to exchange it.
Yeah I tried different outlets, different cords. Eventually I talked to a Samsung rep in Best Buy who saps that Thai cam be fiddly, but what I was experiencing was not normal, Amma I should return it. So I did, and have had no problems since.
I ran some tests with Note5 and Nexus 7 and here is the result.
Samsung Wireless Charger: Note5 NG – Quits charging after few minutes, Nexus7 OK
Cheap wireless charger from Amazon: Note5 OK, Nexus7 OK
Anker wireless charger : Note5 OK, Nexus7 OK
Used 2 different brand new Samsung Wireless chargers with same results.
If I turn on daydream, Samsung charger works fine. But I don't want display on at night while I'm charging. I'm using the samsung charger for Nexus 7 and one of my other wireless chargers for Note5.
Update.
Used Samsung Adaptive fast charger wall plug with Samsung wireless charger and Note5 is charging normally without disconnecting. Weird..
