So no matter where I look, I cannot find good chargers for my GN2. Here I was thinking that I'd be able to use my 10+ white brick crapple charging blocks at 1A and here my awesome GN2 uses a 2A.
Now I understand that Apple swayed away from yet another standard and the pins need to be shorted in almost all car chargers in order for anything other than an apple device to accept an AC charge. Awesome.
I'm very happy that this huge battery needs a 2A charger but I'm back at square one. I need chargers... I need a lot. Please somebody point me in the right direction on what every android peep is doing to charge their phones on fast chargers... I am mostly in need of a car charger. Every forum I look at, the thread ends with no definitive answer...
Much thanks.

This is the charger that I use for my car charging needs. Ive had it for a couple if years and it has worked flawlessly. It also has an extra usb port for charging a 2nd device. I havent had any quality issues with mine like some of the reviewers have claimed. This works brilliantly with my Note 2. It can output up to 4 amps and charges 2 Note 2's with max screen brightness and GPS with no problem.

Hi,
I have a big problem with charging after 4.2.1 OTA update. My phone is unable to charge normally (I tried to replace battery also) by charger, I'm able to charge only by USB and here is charging also strange...phone sometimes shows charging sometimes not.... all this happened after 4.2.1 OTA update... Any solution?

I have just recently encountered this. Been on 4.2.1 for quite a while now and I don't think it's a software issue. Tried bending the charging "tongue" in the charging port "upwards" a bit (as suggested from the link posted above) and it worked. :good:

I had the same issue with my gnex so I tried different chargers that I had laying around the house. Right now I'm using a bb charger and I could feel the difference in how tight the connection was compared to the Verizon charger. Haven't had an issue since.

The Blackberry charger reads an output of 5V and 700mA. Amperage not being a huge deal as long as the voltage is doesn't exceed what the phone can handle.
I just got an Anker Astro 3E that should be able to charge our tablet up to full. The issue is that apparently Samsung devices check for Samsung approved chargers using pin voltages. This battery does not have those specific voltages so instead of charging I get a red X on my battery. Samsung Tab 10.1 users have a flashing solution from what I have read. Is there an application to disable the check or can a dev look into bypassing that?

Here's the link to the mod:

The adapters to enable charging fro many source have been available for a long time and at low cost.
I know the rated current N8000 needs to get from any adapter must be not less than 2000 mA. I don't think your charging adaptor or device offers such a feature: there are very few adaptors passing the Samsung muster. They must be specifically designed for Galaxy Tab; check yours out.
That's why a desktop PC can't charge your N8000, if you plug it to an USB port, the red X pops up right away.

Exactly. Whatever Amperage it provides, unless it is made specifically for Samsung tablet, it will not charge it without the adapter I am talking about. Links to those have been posted multiple times, do a search on eBay.
I use one of these with its own Samsung adaptor plug and it charges the tablet and gives the correct battery icon - http://www.amazon.co.uk/gp/product/B000P13V1E

I found the PWR+ usb filter on eBay but shipping costs to where I live quadruple the price and I'm not desperate enough to pay 15 euro for a usb plug wth two resistors... yet. Someone posted a Pisen adapter in another thread that does the same, looking for this one now.

Can anyone point me in the direction of cables to get that will actually charge up my Note II using 2.0A? The cables I've found will at most only charge at 1.0 A and I was wondering if anyone had any actual cables (like the OEM that came with the Note II) that they could recommend?
I don't want to short out the cables myself.
Also wondering if there's some sort of App that would allow me to force my phone to charge as though it was always on AC power. I'm not rooted.
Any info would be great, thanks.

Yes I charge at 2 amps. It's the actual charger/brick/plug not the cable that pumps the amps. Not only do I charge at 2 amps but I also get good data speeds. Monoprice sells great stuff at great prices. If you can find REAL OEM equipment at a good price I would suggest you get it but if not give them a try.
i use monoprice cables as well. never had any issues.

That's not exactly true. The cable plays a part in how much of the current gets sent to the phone. That's why a lot of the times you have to short the cable so that it reads as a charger and not a data plug.

Well I've been using smartphones for over 10 years and I've never had to short a cable to get it to read as anything other than what it was. Just my guess, if you have to purposely short a cable to get it to work right, you probably have the wrong cable. I use these cables all the time and my phone charges just fine with no shorting. Now I am using the brick that came with my Note II and I use the brick that came with my Galaxy Tab 2 7 when at work, which also charges at 2 amps. The reason why I buy so many of them is because the cord is a lot heavier than the OEM ones and the added weight sometimes makes the connector loose. But Monoprice has a lifetime warranty on all their products and a easy return policy so if a couple do fail over time it costs you nothing to get a replacement.

Yeah, there are several threads about this as most USB cables are designed to read as data cables and therefore do not give you the maximum current for charging. Most people short out two pins to make it read as a charging cable. That's why I posted the thread looking for cables that are already designed as charging cables and not data cables. They're pretty difficult to sort through. Thanks for the links.

When rooting the Galaxy S4 phone, it has been said on this forum that original USB cable must be used. I read people's posts where they said that Galaxy S3 cable did not work whereas using the S4 original cable that came with the phone worked.
I may have confirmed this the hard way when I also could not root the S4 until I used its original cable. The thing is, in addition to using the original USB cable, I also switched USB ports.
So is the cable itself different, or was it perhaps using a different port that made the difference?
I am not talking about low quality cables vs S4 cable, I am talking about genuine cables like the one that comes with S3, is there a difference between it and the S4 cable? I know the S4 charger is a 2 Amp charger, I know it's different and I am not talking about that, my question is about the cable itself.
No you dont need the original that is bs. I haven't used my original at all. I used the one from my S2 and S3 with no problem.

I have only used an amazon .99$ cable on all my phones. Never had a single problem. I leave the original cable and charger in the box.

You will see that different cables give you different voltages for charging. Ive only seen the highest (1900) with my original cable and that charges pretty quick. My s3 cable only charges at 1000 and my sisters crappy phone charger would only push 300 which is not enough to charge the battery.
Sent from my SGH-M919 using Tapatalk 2
Once again, multiple posts in Galaxy S4 threads mention to be SURE to use the original cable, especially when people have problems, and then they report problems resolved after using the original S4 cable that came with the phone. So several people that I've seen, including myself resolved problems after trying the original Galaxy S4 cable instead of the old ones, with one person specifically saying that even the Galaxy 3 cable did not work.
Judging by the post above, it is the cables themselves and not simply what they are plugged into (for example a new 2 amp power source vs older lower amp power sources or even different USB port).
So then the logical follow up question is HOW do you tell you are getting a cable that can match the original Galaxy S4 cable if nobody really lists the cable specs?
Thanks PostMeridianLyf for posting about that app. I just measured all the cables in the house. Some came in as low as 300, found three that came in at 1900, just like the original S4. I suppose the only way to tell is to test them after getting them. There should be an industry standard.
If you're going to charge the S4 overnight, is it actually preferable to use a 300 USB cord instead of the original 1900 cord because the charging would take (much) longer but would actually be easier on the battery life?

I wouldnt think so. If you keep refreshing it you will see that the phone is able to vary the charge and will slow or stop charging the battery when its full.
Besides, its the stock charger for a reason and batteries are not too expensivd either. Just my opinion though, and i dont even think 300 would be near enough

How cheap batteries are is not the point.
If you use a speed charger on regular batteries they will not last nearly as long as when you use a charger that takes several hours to fill them up.
After you go to bed, if you are looking at a few hours of sleep, then it doesn't matter how long the charge takes, doesn't it stand to reason that given a choice, we should choose the slower charging process and extend battery life?
Just try it. But i know for a fact 300 wont even keep your phone on.

in theory and in a lab? yes it will extend the battery life by some statistically relevant amount.
in the real world? you would see a bigger impact from heat (like gaming, using the phone outdoors, etc) on the battery than a slower charging current.
Heat kills batteries, not a sub 1C charging rate.

I don't know what "all" phones means but this is a Galaxy S4 forum and if you use the app posted earlier to measure an old cable, and it happens to be a low current cable, you will not be able to Odin to root the Galaxy S4.
My Galaxy S4 did connect to my computer but I was not able to successfully root using Odin UNTIL I used the original cable which the app measured at 1900 vs. other cables which ranged from 300 to 600 to 900 to 1100. The same was confirmed by multiple users on this forum. Whenever someone has problems rooting Galaxy 4 through Odin, one of the first questions asked now is 'which cable are you using?'
I measured some old cables to match the original Galaxy S4 cable, but there is no way to tell unless you use the new 2 amp Galaxy S4 charger to send the current through and measure each cable using this app: https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free

The main issue here that people are referring to is the pins on the cables. Certain manufacturers are known to use extra pins in the connectors. These serve a few purposes which I won't get into. You may notice on those cables only reaching 300 mAh that the data transfer is also slower. On the factory one, the data transfer will be quicker.
That's all there is to it. Your phone will root just fine. Now, sometimes a crappy charger will really screw with the phone and battery and the only way to "reset" it so it works fine is to use the factory charger. Like when your phone says it's charging even though it's not plugged in.
As far as "trickle charging" a Li-ion battery (ours is a lithium ion polymer battery I think) its worthless generally. Trickle charging is an old trick use on lead-acid and nickel-cadmium batteries. Li-ion works in a totally different way. No real point exists for using that method on these batteries. You might as well charge fast and use your phone than waste time at 300 mAh. Your battery has a chip in it that takes care of all the dirty work. It maintains the proper charging current and will top off the charge as needed while it's plugged in - which is what a trickle charge would do if done correctly.
