I don't know if it's a kernel/rom problem, or a hardware controller that's at fault, but ever since I got this phone charging in car chargers, computer usb outlets, and even alternate wall chargers has been painstakingly slow!
It takes forever to charge, and takes a dedicated powerful wall outlet to even do anything.
Anyone else experiencing this?
The default Samsung Provided Wall outlet charger provides .7A of power, while USB provides .5A of power max. Also what percentage do you charge it at, and can you take a screenshot of your battery usage graph?
The 3rd party chargers that designed for iDevices are not recognized as AC chargers and will be charging at USB mode which is much shower.

According to Entropy512, here is the quote:
Improved battery charge algorithm for faster charging - Initial research indicates we have an alternate battery charger chip (MAX8922) that differs from the MAX8997 used in the I9100. We DO have an 8997 also - but on our device for some reason Samsung decided to use an alternate chip instead of using the 8997's built-in charging. This means we have far fewer options (90,400,660 mA) in terms of charge rates compared to the I9100 (from 200 to 950 in 50 mA steps). So we might not be able to implement any fancy charging algorithms.

So if I am understanding correctly we were limited to 660 mA at max and unless some way to change it is found, there is unfortunately no use from more powerful chargers .

Perhaps you have either a faulty battery or a faulty charger.
Here is a link where you can buy a new battery and wall charger for under 8 bucks for both with free shipping!
Check it out here: http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
Put your phone in to power saving mode and see if it charges faster.
Other wise exchange it under warranty.
I've experienced that this devices charges significantly slower then my previous devices.
I found it odd when I saw the stock a/c USB adapter outputs at .7mA so i did a starch and found an article out there with a statement from Samsung stating that their devices are designed to charge slow because it's healthier for the battery.
I don't know if the charging current is restricted by some code in the kernel or a physical chip in the main board.

It is true that slow charges do increase the overall life of the battery. Also not charging it all the way or discharging it all the way will keep the life of the battery. If you discharge the phone all the way down, it will take much longer to charge than charging it back up from 20% or so.

Can you please post the output voltage and amperage for the battery charger on that accessory? Should be either on a sticker on the bottom of the device our written in fine print on the charger.
Also just to double check, it does not charge a docked device, just the spare battery?

Physical chip. However on other GS2s and original GalaxyS phones, the chip was fairly controllable by the kernel.
Ours isn't - it has three settings. 90, 400, 660 mA.

It is 600mA, and it just charges the spare battery.
I strongly advise against buying third party batteries or chargers. The Galaxy S 2 (AT&T version) uses a battery with NFC technology. Using anything other than an OEM Samsung battery, or an NFC compliant battery could cause damage to your device.

Mine isn't third party. All official. Just cheaper thanks to Amazon.
I recently made a homemade USB battery charger by daisy chaining four D batteries and connecting the positive and negative ends of a USB cord to the correct ends of the connected batteries. The battery works fine; I have tested it on cheap USB powered devices, however, I am wondering if I can use this with my phone as a backup just in case I need to get some more juice out of my phone.
Assuming all the batteries give out the rated voltage, this should produce about 6 volts, with an amperage that I am unaware of. Though this is higher than the 5.2V that the phone normally charges with, it is less that what is produced by a 3rd party AC to DC adapter that I got off of eBay but more than what I get off of the Samsung adapter. I don't have a volt meter, so I wasn't able to get absolute measurements of the voltages; however, I was able to get relative measurements.
Does anyone know if this will cause any adverse effects if I decide to use it?
Maybe you should use the thing a bit else where and have the voltage reduced and try it on your phone
Sent from my SPH-D710 using xda premium
I've used it multiple times to charge another backup battery and haven't had any problems with it yet. Do you know what would happen if the amperage of the battery is too high or too low? Currently I have no way of measuring how it compares to the original adapter.
Bring it into a radio shack and have them connect it to a multimeter, you'll know exactly what power output you are looking at.
I however, wouldn't connect a homemade battery based charger to my several hundred $ phone, just saying.

So I will get the regular charger for gs3 that comes with the phone (tomorrow when i get the phone). but i also have the HP Touchpad charger which gives output of 2.0A. I was wondering if I charge my phone with the HP charger will it actually charge is faster then the regular gs3 charger? the reason i ask is cause in other threads ppl have mentioned that it only charges faster with non - stock roms like aokp or aosp roms. please lemme know if this will work. thanks
It should I got one of those and it does charge faster I got the bb one tho

I've used my BlackBerry PlayBook charger on mine and it doesn't charge any faster. That charger is 1.8amp.
It will not charge faster. The phone only draws as much amps as its allowed to. Whether you use a 1 amp charger or a 2 amp charger, it'll only charge at the phones own rate
Sent from my SPH-L710 using xda app-developers app
then theres basically no advantage to using some other charger?
I don't believe so. The phone only draws what it needs.
Sent from my SPH-L710 using xda app-developers app
A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

I have a dual car/wall charger and I noticed when plugged in the car it charges faster.
Sent from my vivow using Tapatalk 2
The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

the only way I have found to charge phone's faster is to power it off and then charge...takes about half the time to fully charge
none of the 2 amp chargers make it any quicker

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
I bought an Xtreme 2.1 amp car charger but I noticed once charged my note 3 gets hot (110 F when I unplugged it).
Would using the oem cable be likely to help? The Motorola USB to micro plug cable I used did not cause overheating on an ac plug.
Can you suggest a car charger that works well without causing the phone to get hot?

It uses cheap but efficient STMicroelectronic chips,
So it is not a crap at the moment. But it can vary batch to batch on DX as always.
You seem to know a lot about electronics. Does the cable I use matter or is the charger primarily responsible for overheating?

1- if charger has low efficiency the loosed energy will turn to heat on charger. Generally efficiency is near 80% and it translate to near 2~3watt energy loose on full power. It will heat this little chargers very fast.
2- if the cable is too thin or connectors oxided, power loose on cable will heat cable, charger also phone. If the problem is cable charge time will decrease when cable heated. So if your charge time is ok, problem is dc-dc convertion efficiency.
You mention low efficiency getting charger hot. It wasn't., nor was the cable. Only the phone was hot.

chargers output voltage and ripple must be measured.
Voltage higher than 5.5V or voltage ripple can cause this. Charger voltage can ripple from 4V to 6V and you can only measure 5V avarage voltage with standart multimeters. Be carefull and do not use that charger.
Im using this one from Verizon. It works very well and has a handy led light

I got my phone today, and one of the first things that I did was test all of the Chargers.
My first thought is that the one plus cable that I bought is very high quality. Every charger that I tested, it charge faster than the cheapo ones that I bought on Amazon.
However, what I've been consistently surprised with is that using the same cable this phone charges faster on a Qualcomm quick charge 2 charger than it does on a standard USB charger. I've tested this with all sorts of Chargers around my house and I'm consistently seeing around 1500 when connected to a quick charger, and only a thousand when connected to a standard charger.
The USB C charger that came with the phone is significantly faster. However I wanted to share this so that for those others who bought all sorts of Qualcomm quick charge 2.0 Chargers, don't throw them out. They're still better than a regular charger.
Yeah on a good USB 3.1 cable (nice and thick) with my standard quickcharge charging block (7 ports, 60W total IIRC) I get 'charging rapidly' and it charges better than 1% a minute - about the same rate my N5 did on a much smaller battery. I've still not taken the google charger out of its box yet.. Need to get around to testing it even if I can't see myself using it.

I am curious as to what "standard" chargers you are using. I have a wall charger rated at 5v 2.1a (non-QC) per port and a car charger rated at 5v 2.4a (non-QC) per port, and both of those charge at 1500ma. Is it possible that your "standard" chargers are only rated for 5v 1a output?

Bought that one though still waiting on my phone. Like that it has micro USB too for other devices. Charges my HAM2 very fast.
Your results have nothing to do with them being QuickCharge bricks, I have a inline amp meter and I can get 1.5 on any brick with an amp rating high enough, not just my QC bricks that I was using with my Moto X. At least people will know if they have a QC brick they'll get at least that though.
I didn't know this thread existed. I'm getting what I think is pretty poor performance from the stock 6p charger. Please see this post:
