not sure if this is good for the battery to leave it plugged into the charger when it's at 100%..
i been told before that these new devices it's ok to leave it plugged in...but i don't have a good feeling about this lol
it'd be great if someone can please chime in on this.
thanks all!
Yes it is OK. The charging circuitry will switch to a trickle charger when battery is almost fully charged.

the charging system is getting more and more intelligent...no reason to worry about that anymore
Just keep your batteries with more than 20-30% charge as much as possible.

I leave my phone charged to 100% almost all the time:
- when I am at work I leave it plugged to the USB port
- when I am working at home, the phone is connected to the USB port
- when I am driving the phone is connected to the vehicular charger
- when I go to bed, if the phone is below 70%, I leave it plugged on the wall charger overnight.
Yet, when I am on long bike rides and the 3G+ data + GPS + synch are enabled, I still get excellent battery times.
Over charging any battery isn't very good for it, it's the same with laptops and well pretty much anything, so long as power is coming in the battery will take it, even if it is at a slower rate.
Ideally you would want it to charge to 100% and then a little bit more, maybe 20 mins, to make sure.
However i know we don't live in an ideal world and charging it overnight is the only thing that can be done by most users.
In my work we have a lot of phones plugged in all the time (all brands) and they have some strange effects happening, eg: Unresponsive touchscreen (removing the charger solves this), Poor battery life, glitchy screen etc.
Saying that, all of our phones are plugged in all of the time so it is an extreme situation.
If your worried about it then get a timed plug so it only charges for a few hours and then cuts off.
But you should be fine otherwise.
Just feel the charger when the phone's at 100% and it's giving off a f**k load of heat because the phone isn't actually taking anymore charge and the charger turns the reduced MAH it draws into heat in the charger, so just don't worry about it because the phone does all the work for you and can't go over a full charge.
My phone stops charging at 100%.

Instead of creating a new thread, I'd like to steer the ci bvr station towards what charger is it OK to use.
For the ones who know their stuff, can I use any USB charger or must I use only the Samsung charger that cane with the S3?
I remember reading the circuity that allows a proper charge is specific to Samsung chargers.

Yeah you can use any Micro USB cable or charger as long as it outputs no more than 1000mah.
I thought a higher output was "good" in that it reduces the charging time.
Could you please explain why one must take into account a limit?
Conversely, is a low output harmful: how about charging from a laptop USB port?
Also, I have a HTC One X. Can I use the Samsung charger with it: how do I find out the output limit for the One X?

A higher current can damage the battery and possibly the phone and some people say the phone at any current above 1500mah but still haven't seen any proof yet, and you can probably get away with 1300mah but the more you the the hotter the battery gets then slowly expands and might pop, and yes you can use the HTC charger no problem but check any charger you use for output current wrote on charger, and also yes you can charge from a laptop or any really slow charger you like.

Correct me if I am wrong, but I thought the Samsung phones block excessive current and can accept up to 1amp. Also when using any charger that doesn't have the middle cables short-circuited would produce 500milliamps regardless of charger's output(this can be turned off with custom kernel). That's why there is a list of car chargers on gsII or Note forums that have the pins shorted. That said, people had reported that using HP touchpad cuts down in charging time while increasing heat.
I am looking into this a little more and some useful info I found.
My GT-I9300 charger outputs 1000mA @ 5V. The phone charges up quickly. No problem there.
When using a USB port on my Macbook Air (2012 model), under About This Mac > More Info... > System Report... > Hardware > USB > bottom USB High-Speed Bus Hub listed: I see that 500mA are avail from the USB 2.0 port (conforming with USB 2.0 standard specs), but the GT-I9300 is only requesting/ drawing 96mA, whether I am using the original Samsung USB cable which came with the phone or my favorite short Jawbone ERA USB to microUSB shorter cable.

It just takes much longer to charge.
My One X (S720E) draws the full 500mA avail from the port:
It should be noted that some Apple peripherals/ devices (iPhone, iPad etc.) can request and get an additional 500mA from the port on computers/ monitors that supports this.
Here is the Apple Support Article that covers this.
Pretty much everything uses Lithium-Ion these days, and it's perfectly safe to leave overnight, heck I even upped the AC charge voltage to a straight-up 1200 on AC power.
Charging at lower powers is equally harmless, but if you use the phone you may drain faster than it can charge.
All in all, thse rumors about decreasing battery life are getting sillier and sillier these days. Earlier batteries were a bit finicky, but they have improved A LOT, and honestly, a new samsung battery costs 25 dollars? If I'm still using this device in 3-4 years when the battery finally gives out I'll be very surprised.

Hey guys I'm looking for a car charger that will charge the phone while running google navigation. The current one I have cannot keep up. Basically the phone is using more battery than the charger is supplying so eventually even though it's charging it will die. Please help with some suggestions.
The higher the output amps the better, most online don't say.
This one has a 1A (1000 mA) which is the highest I've seen until now.
http://www.cellphoneshop.net/2usbcar.html
This says 2.1A.
http://www.amazon.com/dp/B004U4RF7I...e=asn&creative=395093&creativeASIN=B004U4RF7I
Here's one that has 1 of each (1A & 2.1A):
http://www.scosche.com/consumer-tech/product/1921
You need to be careful about using one too high for the phone as well.
The output of the wall charger that comes with the phone is 1A. Find an USB car charger that outputs 1A and you should be fine.
This will run Pandora&Navigation at the same time and still charge,but not by much. But a least it doesn't discharge.
*LINK*
The phones are only meant to charge up so fast. once you attempt to go over that limit, you risk causing damage to your phone. don't look for something with so much power it charges it in 20 minutes. it will kill the phone and battery.
Is 2.1A safe from charging phones?
Sent from my EVO 3D
I doubt the phone will charge any faster even if you get a 2A charger, but there are many chargers that only charge the phone half as fast as you possibly could. Some chargers only provide 0.5A (500mA, conforming to the PC USB spec) and some 1A chargers will only provide 0.5A because of the pin out on the connector plug... You can tell this is happening if under battery stats in settings it says it's charging from USB instead of AC. You could short some pins on said chargers to fix that but it's usually easier to find a proper one for $3 or whatever.
Even if you have a 1A charger you could manage to discharge faster than it charges if you're streaming music while using navigation for a while and/or you happen to be in a low signal area (which eats battery like crazy since the radio goes wild trying to find a better signal/tower).
I have the one in the link below. It is OEM HTC for the Thunderbolt, and has
2x 1A Ports. It keeps up with
Pandora and GMaps. My old charger would not (it was 500mA.) The cool thing is that both ports are 1A in a small form factor, and it has a white LED that illuminates them. It comes with a coiled cord which is well built.

You have no idea what you are talking about. The rating indicates the maximum current the charger is capable of. The phone will decide how much to draw.
Actually, the high rating is not enough. The charger should have a certain circuitry ( a resistor between data pins) to "tell" phone that it can supply higher current. 2.1A iPad charger doesn't have it because it was designed to communicate with iGadgets. It will act like a regular 500mA charger when connected to an Android phone.
A lot of the 1amp chargers that you see will still only charge your phone at 500ma. Unless USB pins 2 and 3 are shorted together (or have less then 200 ohms between pins 2 and 3), the phone will think it's connecting to a computer and only draw 500ma. I modified a few 1amp chargers to actually charge at 1amp instead of 500ma. See this thread:

Are you SURE you're getting the right result with the Current Widget? There's been quite a few threads on this topic and it doesn't seem that the Current Widget correctly supports our phone. Per that widget, I'm getting 400ma current draw normally - without running any active apps. When I use various chargers, that number goes up or down seemingly at random, LOL.
My most powerful charger, which provides 2A on one port and 2.1 A on the other - makes the widget report only 35 mA.
In short - I wish there was an app that correctly measures current draw on our phone, but I haven't found one based on multiple threads on the topic.
I use Battery Monitor Widget. I definitely see the difference between 500mA and 1A chargers. Some current form the charger is consumed by the phone itself, so it is not possible measure the actual draw from the power supply without an external meter.

I have the one from Sprint with the AC adapter in it that pops out and it works well. Granted it was a bit pricey, but, it does the job and the battery does in fact charge while using telenav navigation and listening to music through the stereo as well. Slowly, but, at least it doesn't discharge while being charged....LOL...

This is one of the few chargers that would power the Palm Touchstone reliably. There was an extensive thread at Pre Central on car chargers. Just make sure it's the SPN5400A like in the link above. Some other Motorola chargers have a lower output.
On the E3D it shows charging on AC.

You can get a 2amp charger but the kernel must support fast charging.
Even then i dont think full charge within an hour is possible.
Thanks for the respond.... But not to use with the phone only for the battery. I have a seperate charger for the extra battery but it feels like it takes forever. I do rate it over the phone charger though because if I fully charge the battery with my phone and I take it out and place it on the external charger it shows that It still have around 10 to 15min left to complete charging... I beleive it's correct because it seems to last longet than charging with the phone!!!!

Not trying to revive this post, but noticed people are looking for a fast charger. I have a Touchpad and use the charger to charge my Note. It charges much faster than the OEM.
It is a 2+amp charger. It says 2amp on the label. I tried to charge my Touchpad on a Ipad charger (also 2amps) and the Touchpad said gave a warning saying it will take longer to charge. So I assume the Touchpad charger is 2.5amp. (max allowed for FCC)
Long story short, its on sale for only $4.99. Go get it!

Both the AC wall wart that comes with the Note (I assume that's what you mean by "the OEM") and the HP TouchPad AC charger will charge the Note at 1 A. One is not faster than the other.

No, this is because the iPad charger is wired up to supply 2 A only via the proprietary iPad connector. If you connect it to a micro USB device (like the Touchpad or the Note), you will not get 2 A. You will probably only get 0.5 A, which is the USB standard. That causes the TP to display the warning you saw.
Thanks guys but I still didn't get the answer I was looking for. I'm looking for a universal wall charger that could charge batteries by itself but at a faster pace!!

No. The Note (and most current Samsung hardware) is limited at just over 1A. I'm using a 3A charger with a change-only cable and my Note can only charge at ~1.1A according to CurrentWidget. Without charge-only cable it's half an amp at best.

Well Charging seemed very quick but the CurrentWidget showed charging from 1A to 8A. Listed on their Google play page they say that Samsung probably isn't supported.
The electric current reading doesn't work on all devices. The reason is that the manufactures (mostly Motorola and Samsung) don't support this in the battery driver or in the hardware.

I've never got off-the-wall amperage #'s like that on my OG Note. I know it's accurate because the Samsung OEM wall charger is 1amp and my phone shows 1100~mA when plugged in. It shows the same #'s when plugged in to my 3amp car charger with charge-only cable.

Is there a fix or work around to the slow charging issue? If I use the stock charger and cable that came with the DNA I am fine, but my OEM Thunderbolt charger (which looks the same) and my car charger I got from Amazon (which I understand may be a knock off but had worked before on the DNA) or any other charger give me a slow charging notification.
This is a pretty big deal for me since I use my phone a lot for work. If I am in the car my phone is not charging fast enough to keep up with drain from the navigation.
I am rooted, s-off, twrp, and running Viper ROM 1.2.0. I understand HTC implemented this "feature" with the latest update. I couldn't find any info about a fix so are people just dealing with it?

You can flash a kernel like crpalmers or zarboz's kernels with fast charging implemented. But what I recommend is buying a USB charger that wont have that issue.
Take your phone somewhere that they have a Nexus 7 or Asus tablet set up on display with the regular charger hooked up.
They sell the chargers lots of places, the Nexus 7 will be best both spec wise and it comes with a pretty nice micros USB cable but I see the transformer prime charger in more places to walk in and purchase retail brick and mortar.They're solid chargers that will deliver the power your phone will allow. You just have to be careful when using it when charging with fast charging enabled it gets warm because it's running that current through their. The OEM charger only runs about 70% of the rated current through there.
Best Buy has a RocketFish 12volt car charger micro USB with an extra USB slot for a second USB cable and device. I almost never use car chargers but I was actually impressed with the quality of this charger. Also HotTips makes a charger that's rated at 5.0 amps and I believe as long as it's not a cheap crumby USB cable it will work fine. A lot of times it's the cable itself not the charger, so I would try taking your USB cable from home to work and plugging it up to that same USB charging plug and see if you get the same slow charging icon.
Thanks for the thorough response. I tried to do some testing combining different cables and charges and the only one that consistently gives me slow charging is the car charger (which worked fine previously). I have a Transformer Prime charger and Droid Razr charger that both worked fine. My Thunderbolt charger worked when I tried this time but has given me the slow charging notification in the past.
I may have to pick up one of the car chargers you mentioned because that is the most important. My phone is running great otherwise with Viper ROM and the kernel that comes with it so I'd rather not change it.

or you could always get a power inverter and then use whatever cable you want.
Get the Verizon car charger. Works fine for me..

I ordered these cables from Amazon, got them today and I'm still getting slow charging from the car charger. These are really high quality and still not working. This is pretty ridiculous, HTC should have at least made this optional.
I posted on this a while back, its the cable that causes the issue. If you open up the cable and short the data wires it works perfect. All you needs is wire strippers, electrical tape and shrink tubing.

Thanks for the suggestion. The cables I bought are very high quality, charging specific cables, and I'm still getting slow charging in the car. If HTC only wants to support official OEM chargers that's fine, but then they need to make an official car charger!!
Also, why does HTC only support using the OEM charger when the DNA supports Qi charging? Doesn't make "Sense"

I tried that with the Rezound awhile back and afterwards it still registered as 'charging USB'(aka slow charging).
P.S. that Motorola charger I mentioned above, I opened one up before and noticed it just had the 2 power cables(black & white) and they were also much thicker then the standard cables w/ all 4 wires.
When I did my cable hacks I cut the cable in half, put a piece of shrink tubing on one end reconnected the power wires, shorted the data wires on both plugs. When you do this you cannot reconnect the data wires. They must be separated. I'll post some pics in a few to show you what I mean.

Basically this is what you want it to look like...connect the positive and negative, you can reconnect the shielding too. Also I highly recommend soldering the wires together. Adds strength.

You can do the cable hack shown in the post above as some non OEM chargers do not have the data wires shorted at the charger itself. You can either hack the cables, or if you need the cable for data, then modify your charger. Please make sure your charger is rated at least 800mA. Any charger rated 800mA or below will charge slow. Computer usb ports are rated 500mA and this is why it charges slow. My car's radio has a usb hook up and it also charges my phone at 500mA which is not enough if I'm calling, navigating, etc. The OEM charger is rated 1A. You can use a 2A charger as well but don't use it everyday. Higher rated chargers do charge the battery quicker, but at the expense of the long term battery life.

In my testing even shorting the chargers data pins on chargers seems to be more of a miss. I've done a few and even after shorting them they still state USB mode. It mainly stems from the data pins being present in the cable itself. Two of the chargers I shorted were for a vehicle and they were rated for 2.0 amps. Also if just charging the phone yes don't use high output chargers. But if charging in the car high output won't hurt if you are using navigation, music etc...it actually needs the higher output to charge hence needing to charge at the AC rate.

Charging
I have this issue as well now, I never had it till the update back in Feb. I used other Android phones on my car charger and they charge just fine and it only happens with my DNA. I think there is a firmware issue that is causing this to happen.
This afternoon I hacked a cable as shown above, to use with my car charger. I'm glad to report it worked like a champ and my phone went from slow car charging to very rapid charging.
Thanks for the tip.

Does anyone else notice that the charging on the phone is slow? The charge even goes down as i'm surfing the web with it plugged in. I'm currently using the sony power brick that came with it. I'm experimenting with different ones at the moment. Right now I'm using the Vita charger. But compared to how my Note 3 charges, this one pales in comparison.
Please provide tips if you have any. I am currently in the mood to purchase a car charger as well.

What cable are you using to charge it? Try using the original cable. Android phones usually charge at a maximun of 1.5a so the one that comes with the phone it's Ok.

I was using some generic cable, not the suplied Sony one, cuz I thought they were all the same.
my phone came with European charger.
So I bought it this Micro USB Quick Charger from the US sony store. It's coming with some over voltage to charge quickly.

With that kind of voltage your ultra doesn't stay thin very long mate, definitely an error on the site.
You can't put more then 4.2V per cell. When it's more it will explode, in our phone there is one cell. My acer a700 have 3 cells, so that unit is charged with 12.6V.
You can charge faster by raising the current. Our cell is 3000mah, normally charged with 1500mah (0,5C). It should be fine to charge with 3000mah (1C). If the cell is decent quality it will take 6000mah (2C), but this reduces the charge cycles significantly. When the cell is inferior it will slowly starts to swell.
Everytime you double the amps the charge time halves (theoreticaly).
I would stick with 1500mah, done in 2 hours. There's always possibilty to charge.
This is what happens when you put more then 4.2V per cell into a lipo accu. In our phone there is a lion battery but this is almost the same. Lipo has a higher energy density.

I've been using different chargers and different cables, all at least able to charge at 1.5 amps. My results have been essentially the same: If I leave it alone, it charges rapidly, I'd say at about 2 hours and some change to full. However, if I start using it (especially on high brightness with lots going on) the charge slows down to a hault. This is the same on most Android devices. From what I've seen, the new snapdragon 800 chipsets are able to at least continue charging even through heavy use. Just not very quickly. I know the galaxy devices don't even charge if you use them heavily enough (with the exception of the Note 3 of course).

I've experienced this with another device, it was caused by a faulty usb cable. One of the wires inside was almost cut, there was only connection with a couple of the twisted core wires. 80% was cut, big increase in resistance.
I did a massive study on lion batteries last year, and found that voltage does have an impact. (pulled apart my battery and used various voltage/hz/amp input...
The major issue with the input is the heat. If you quick charge it for an hour then you are fine. But using quick charge, and then using your device will cause massive heat because you'll be charing it for more than an hour, and using your device uses CPU... (goes without saying).
Expanding and contracting the battery is what causes decay. The material inside the battery that holds the positive ions will crack and cause less 'hold' for these ions. This will result in less ions being able to be stored.
This also may also cause hardware issues flexing the internals.
result:
5v is fine, it comes down to 1.5 - 1.8 amps input... anything over that and you'll really need to check on the heat of the battery. There is also a sensor that detects input and output of amps. This sensor can get fried easily, so be careful not to wreck it!
What ever you do... DON'T put your device in the fridge or freezer if its hot. That will cause massive temp change, and mess with more than just your battery.

It's very normal for a charger to get warm. You should watch the battery, that should not get warm.

I have this http://www.siig.com/3-1a-dual-usb-car-charger.html and it doesnt charge my Note 3 at all. It just keeps it at the same charge, and shows up as USB under battery settings when plugged in
Then I bought this http://www.amazon.com/Kensington-Po...05&sr=8-4&keywords=kensington+4.2+car+charger and for some reason one port shows up as AC charging and the other as USB. Its supposed to be two identical 2.1 amp ports, so why that is happening is beyond me.
Can someone please recommend an app that works well withe the Note 3 to measure current?
Can someone please recommend something that will actually work? I basically want a charger (for car) that can charge my Note3 and my wife's, at the same time, at least at the same speed my OEM charger that came with the phone does.
Does what cable I use make a difference at all?
Thank you for your time
I don't have the GN3, but a GN2. I have and use Ventev 4.2A rapid car charger. You may want to try it. It works well with my GN2. What's nice about it, both ports are 2.1A 5V. I was hoping it would charge my GN2 and ASUS Infinity Pad tablet at the same time, but the tablet needed 15V. Thus, it's end up being trickle charger for the tablet, but does slow down the battery drain.
And it's pretty cheap. Seems solidly build. I also have the wall charger unit and works well too. It may just do the trick.

not much from what I can tell. Both have 2.1A ports, totaling 4.2A. What I was able to find (specs), the only difference is the case and price.
I didn't look at your second link. I thought you were looking for suggestions on a charger that could charge two GN3 quickly. I'm still a bit annoyed with many andriod 10" tablets needing 15V to charge. I have car cigarette power inverter with a AC plug outlet and two USB ports (2.1 and 1.0) that I can use that will charge my tablet quickly.

Well you are correct in that I am looking for suggestions, but since the charger you posted about is identical to what I bought, I'm wondering why the one I bought isn't working as intended. Hopefully somebody can chime in. Could it be that the Kensington isn't actually 5 volts ?

There's also a Pro version for $0.99 as well. I use the free version and it works just fine, but there are ads, but that's expected from a "Lite" version of an app.
Thank you for the app recommendation. It has been helping. So here are some results.:
Using Kensington adapter, I get 350mah on both USB ports using a regular micro USB 2.0 cheapo cable I picked up at Frys for 2 bucks. Using another cheapo cable but this time 3.0, I get 1200 mah in one port and 450 in another.
Any ideas?

Try using OEM cables or at least high quality 3rd party cables. I ran into an issue with note 2 where my third party cables only charged at 250mah. When I got a replacement it jumped up drastically. Also car will be different than house wall outlet. Compare both.

Then looking at others forums and checking out my own phone I realized that the phone only charges at 1200mah while the screen is on no matter what chargers or cables you use. When the screen is off then is charges at 1800mah like normal. Samsung built this into the phone and I have no idea why..

When I had my issues I ended up averaging 1800 mAH on an oem. I used the Galaxy Charging Lite app as well. (Edit: just realizedthat's what you used too)
Just in case, you may wanna try another app. Usually the apps just measure the input based on what software tells them so there is a bit of inaccuracy but not enough to be way wrong. Truest test is an amperage meter or something like that. But 1800 on Wall adapter sounds right bad on a micro usb (2.0), I haven't tested usb 3.0 but it should be higher I would think.

This is my limited understanding that comes from researching this myself....
USB has 4 pins that our phones care about. The 5v+, 5V-, Data + and Data -. The 5V pins charge the phone. The Data pins tell the phone what rate to charge at. I believe it is specifically the voltage the phone senses on the data pins. There are some DIY mods out there to use resisters to change this and force a higher or lower charge rate. Those mods were a bit out of my comfort zone so I just skimmed them.
Also, Apple and Android do this differently in some way and most high voltage chargers have iphone and android specific ports because of this (whether they are labeled or not). The Anker car charger I got does this. I don't know of a reliable high amp car charger that has two "android" specific ports. I have tested the Android specific port and it seems to charge at the same rate as the wall charger that came with the phone. I will try and make time to test the "iphone" specific port on my Anker charger to see what mah I get and if there really is an appreciable difference.

If it is not too much trouble, can you download the galaxy current lite app and tell me how many mah you are getting in your house charger and how many mah you are getting in your Anker Android port? Also, I'm assuming you got a Note 3?

The app will tell you 1200 if your screen is on - after is been plugged in, make sure your screen is turned off, then quickly pull up the app after you turn your screen on and it will show 1800

Here's what I've been using. Great so far. http://www.amazon.com/dp/B00GANTT94/ref=cm_sw_r_udp_awd_HsY3sb034XV0R
I bought a dual outlet 4.2amp charger at big lots (got 4 of them actually on sale $10 a pop) that is 2.1 amps per outlet. I use samsung cables with it and my note 3 charges are full speed no problem.
I would just bypass all this and get an inverter for the car and run the OEM charger... takes out all the guesswork and charges exactly the way you are expecting.
Example... turns your cars 12vDC into 120vAC
