problems charging the note 2 in the car - any ideas? - Sprint Samsung Galaxy Note II

here is my setup in the car and i can't get the note to charge - well, it does say its charging but at best it will maintain my charge level it never actually charges
dedicated charger into my fuse box
note hooked up with mhl to my pioneer appradio 2
gps running, mhl running, bluetooth running. i use a screen off app to totally black out the screen.
now, this setup with my gs3 worked perfectly it would charge the gs3 like crazy as fast as a wall charger it seemed. with the note it will never increase in charge but at best maintain or slowly use charge. the power it is getting cannot keep up with all the tasks its doing.
now, i know this phone is a beast...but can anyone think of anything for me to try or buy to get this charging no matter what? i figure it may take custom kernals or something like that to finally get it done.
that being said - if you are using an android phone you absolutely must check out the pioneer appradio 2 with the appradio liberator app. you hook the phone up via mhl and with the app have full touchscreen control and mirroring of your phone on the 7inch touchscrreen radio display its pretty awesome.

I know the wall charger is a 2A rated charger....which is built for tablets. Perhaps attempt to locate a travel charger rated as such. I'm no scientist, or electritian so I cannot attest this will work, but just thought I would throw it out there

my chargers i the car claim to be 2a but doesn't seem to make a difference. hell, the one charger would chage an ipad in the past

most samsung tablets need an adapter to "trick" fast charging mode on non-samsumg chargers. otherwise it'll just trickle charge. i've not tried any yet but seems i may have to since the gnote2 is gonna need the same juice as my gn101. kinda what i expected since they're pretty much the same specs.
here's a thread to make your own adapter:
http://forum.xda-developers.com/showthread.php?t=845844
page 9 has a few links buy your own. just put .com in place of .co.uk on the ebay links.
here one for $3. ships from china so it may take a few weeks.

the stock AC charger supplied with the note 2 is 2A. I also have a 2A car charger. I cannot get the note to charge at any rate higher than 1A. Yes, i do know the trick to get the phone to go into fast charge mode. I have a feeling that 1A is the most we are going to get. Yes, if you have a ton of stuff running all at once you are going to use more than 1A and end up with a dead battery after a while. It does suck. My previous phone (Epic) would not charge beyond .5A. It died while on my car charger ALL the time. Hopefully this one wont die quite as often.

I've just ordered 3 of the $3 ones from deal extreme. it'll be a while before I can test it on a gn2. I'll try them on my gn10.1 as soon as they come in.

Yes, the trick i use is to short the two data lines going to the phone NOT towards the charging source. If you do not do this the phone will be in USB mode which will only allow a charging rate of .38A. This seems to be an android/usb standard across almost all vendors. once i short the data lines that is when the phone will go into full charging mode. The highest i can get the phone to go is 1A and this is even with the supplied Samsung 2A charger. I have also tried an iPad charger and it still only produced 1A to the Note II.
The Note II also seems to vary the input current based on how much battery is left. If the Note is very low (i.e. 50%) it will go into 1A. If the battery is high (i.e.95%), the current will bounce around. I have seen it start at .5A, jump to .8A, then to 1A, then right back down to .5A and it will continue there until it reaches 100%.
Bottom line i have not seen anything above 1A
JD

at least one of the adapters on the other thread claims 2A, but i don't think i've seen anyone with those results.

this is a pretty ridiculous problem for samsung to do nothing about is it not? the notion that you can't even charge your note in the car is a bit ridiculous. i wonder if someone makes a kernal with fast charging enabled if we'll be able to get around this

you can charge, just ridiculous slow. i occasionally charge my galaxy note 10.1 on my computer's usb when i'm too lazy to whoop out the charger. i do it a work where i know i won't use it for 8 hours.

You can't charge if you are intensively using the phone though. it loses charge.

Is there a specific car charger yet for the Note 2? I imagine this issue will be resolved with that charger.
People with the HTC Flyer/Evo View had similar issues. Unless we use HTC proprietary car charger, you lose power while plugged in. Standard usb chargers, charge it very slowly.

I am using the PowerGen Dual USB 3.1A 15w High Output Car Charger since it claims to be a 3.1A charger. What I thought was a fast charge was in reality not. Using the Current Widget app (which shows you the mAh) it registers 9882 mA for one of the usb slots and 10005 mAh for the other using the Galaxy Note 1.

so does that charger actually charge your phone then ?

Yes, just like a regular 1mA wall charger, but not like the 2mA one that comes with the Note 2.

there is no "right" output
most usb ports will charge up to 500mA
the stock usb wall charger is, i think 750mA, i havent looked at it in awhile since its behind my desk, but i know its not 1A
the oem nexus one wall charger (non usb) will charge up to 1A
I would only recommend a 1A charger because there's no point to use a lower amperage, it just takes that much longer to charge your phone.
Couple of good threads on this topic, both on the vibrant and the i9000 acessories thread. Lots of good info. The deal extreme chargers look promising. Waiting to hear from a person who bought a 2amp charger if the extra 1a is used by the phone especially when using gps.

well, my phone will still charge (slowly) while watching avatar, which i would assume is a pretty high load on the cpu, using the 1amp charger i got from dealextreme.
fwiw, the one i have is a 1A "HTC" wall charger thats square and lights up HTC when charging, it ****s up my screen sensitivity so i wouldnt recommend it, but it was only like four dollars so i'll live with it.

AC charger or car charger?
The charger does not dictate the amount of current given to the phone. The phone will only draw what it wants to. The charger can limit the maximum current but if the phone only asks for 700mA, a 2A charger will only provide the 700mA demanded by the phone.
I don't know what the max current our phones will use but having a larger charger will only help if the phone requests the larger current.

I'm not sure how stressful watching Avatar is from a current draw perspective. The torture test is to turn on 3G, Bluetooth, synch, GPS and run the Navigation app while driving. Some post indicate that only a true 2A charger will be able to do this w/o discharging the battery. 1A ones can only limit the discharge. Cheap ones empty quickly.
Could you check what your charge current file value is for your 1A DE charger? Make sure to use the original Samsung cable and cross check with the original Samsung charger and a USB port.
1) Use an application like ES File Manager or Astro Filemanager
2) /sys/class/power_supply/battery/batt_chg_current
Here are the 2 threads that I've found have a lot of charger info.

i checked the file when using the HTC cable plugged into my work dell and it said 850-860 after checking a a dozen times
plugged into the wall charger now and its around 700-750
is that supposed to be reporting in mA?

Yes, but I haven't heard that anyone has measured it. The numbers you are getting are consistent with what others have see. 800-900 for USB. The original Samsung 700mA charger is getting 900-1100.
If you have another Android phone try that one as well to see the differences (e.g. G1 ~300-400).

Faster charging times

Just posted this in another forum. Heres the link:

So you charged the note with it in one hour?
Isn't there a limitation on the current the charger outputs while charging?
I didn't charge the Note. I originally posted this in another section for another phone model if you follow the link. I posted the thread here cause Note owners would get benefits from this charger in quicker times. I do like this one better than Apples 2A charger. Hp's is sleeker, compact and comes with a 5ft cable.

Thanks for the info. Just found it on Amazon for $9.88.
Every phone charges slowly from PC USB port, right?
Do you think this would be safe? It's a cable that is designed for portable hard drives, to give them enough power. Maybe it would give the phone too much amperage (?)
My quick research finds that a typical PC USB port (and for sure Mac) has 500 mA power, so if you used this cable with two inputs, you'd be giving the Note 1000 mA which is basically like the wall charger, so it should be safe. What do you think?
I've used it for 4 full charges and the battery stays cool but charges fast. No problems to date. It's been a great find.
Well, i have been using the charger that came with my Galaxy tab wich is 2 amp, since atday one.
No problem at all. It charges in little more than an hour.
I also have been doing this for more than a year with mi exiphone and the charger from the Ipad.
Maybe in the long run the battery life suffers, but i haven't seen anything like that. And honestly, waiting two and a half hours to get the phone charged via regular charger and ready to go me is not an option.
Going to order one right now and give it a try.
Does anyone know of any car chargers that can charge at about the same speed?

So, following the same logic - the iPad charger should fit too. I am testing it now - so far so good.

I installed the Battery Monitor Widget. It says Techno: Li-ion 1500/1500mAh. This is obviously incorrect for the Note. So can anything it says about the Note's battery be of any use?

Do the Apple 2A chargers for the iPad work for "fast charging" the Note? I know when I bought one in the hopes of fast charging my Galaxy S it didn't work. The Galaxy S just recognizes it as a regular USB charger. No matter which USB cable I use (even the OEM Samsung that came with the GalaxyS)
The charger I bought was this one from Macally, the CARUSB10 and it does not work for fast charging:

However, if I use my Samsung AC wall charger or my Wife's car charger for her Blackberry it is recognized as a "AC" charger and I get the good charging speed.

OEM charger output vs. high output car charger

IIRC the stock wall charger is rated at 1.8Ah. But, what is the phone's actual draw? Does it ever get up there near 1.8mAh?
I'm just trying to figure out if a car charger with "only 1000mA" will be sufficient. I'm guessing that the OEM wall charger is rated well above whatever the phone might ask for, but as to how much, I don't know.
I'm actually looking at these two right now as they both seem to give a pretty high output for both Android and Apple devices.

My experience with other phones is that the phone draws exactly what the stock charger gives it. I'd imagine it's the same with this one. 3140mah is a lot of battery to charge.

I'd agree. I charged it the first couple days using the OGP wall charger and USB cable from my Nexus 4. It took all night. Switched the cable with the one in the box, and it charges in like an hour!
I have a 2.1a car charger, and the OGPro charges in exactly the same amount of time as the stock wall charger.
Oddly, it charges slower from my 2a Note II charger.

Im looking at all of the chargers from Anker on Amazon. It seems they have the best positive reviews of anything I've seen. Although the 3.6 watt (white unit with either 2 usb ports or one port and a micro usb cable) unit is newer than the 3.1 (black heavy duty), the black unit can give the full 3.1 watts to either port or split it amongst the two ports. And according to Anker, either port will work for Apple or android. They suggested i get the newer (white) unit, but i want to have the full 3.1 watts available to a single port for future h higher powered devices.
I'll have to check those out. I've been looking at this one, which has good reviews on it.

My concern with that one is that it gives a total of 2.1A. So if you charge your OGP using one usb port, there's only 0.3A left for the other port. The disclaimer at the end of the description says that if you are charging an iPad to not use the second port. I'm guessing that warning would also apply too us with the high draw OGP. It also states that the blue light gets even brighter in the dark. You might need to cover the led if it's too bright,but that's a personal taste thing,and it might not actually be that intrusive. Lastly, do you have enough room in your vehicle to rest both your phone, and the head of the charging device? I have a dual outlet 12v supplier in my car, but i bought one that has no cord. The two outlets are rigidly mounted right at the end of the cigarette lighter plug.
I bought a Griffin Powerjolt single USB at Walmart. It only charges at full speed using the OGPro's stock cable. Any other cable is slower, and the cable from my old S2 gives me a "Slow Charging" notification.
Anyway, this charger is just a stop-gap. I'm going to be hard wiring two USB plugs into my truck's 12v system (with some 5v regulators and an Add-a-Circuit).
I was looking at the 3.6A charger, here's the link on amazon.
As I expected, one port is for Apple and one for Android. This is very irritating because I need to charge my OGP while my fiance charges her OG at the same time on trips.
Can our OGP charge at full speed on the Apple port?
Edit: I just read that the kernal in Android 4.2 fixes this issue so we can charge in any USB charger, including apple chargers. I'm guessing LG devices still on 4.1 won't benefit from this update.
Shouldn't going to Settings > PC Connection > USB Connection Type and then setting it to "Charge only" force the device to see any cable as a charge only cable thus making it charge faster?

As per Anker, the Apple port will charge Android at full speed. I have not verified this myself as I have not gotten mine yet, but that's what I'm told, and expect. I'm waiting for their wall charger to come back in stock as the shipping will be free if l order both.
I ordered the black 3.6v version. I'll get it Monday or Tuesday since I have Prime.
Are there any apps that detect how much juice the battery is getting?

I just made the charge cable linked in the post above. It works like a charm
I also purchased This wall charger which works perfectly fine with our phone on both the "A" and "NA" port.
I'm willing to bet this car charger made by the same company as the one linked above will work also.

Faster Wall Charger (Updated with results)

Hello Everyone,
I wanted a faster and better charger for my Nexus 5. After doing some research I came up with the following possibilities:
From Amazon:
http://www.amazon.com/Tech-Armor-Charger-Watts-Black/dp/B00CD0HGDE
http://www.amazon.com/iXCC-Charger-Charging-Samsung-Package/dp/B00FCISG6K
http://www.amazon.com/EZOPower-Charger-Adapter-Smartphone-Cellphone/dp/B00EDU5X6Y
All these chargers have 2 USB ports, which they are great if you need to charge two devices at once. They will charge 2.1A from one port and 1A from the other. My problem with all these is that they are bulky and two of them have ports that come out of the back. It can be difficult to use if you want to plug your charger lets say behind your bed or similar tight places. That is one of the reasons why I don't like the stock Nexus 5 charger as the USB cable comes out of the back and its only 1.2A
From eBay:
http://www.ebay.com/itm/OEM-BlackBe...o-USB-Compatible-Phones-Tablets-/200976069483
This charger is exactly what I'm looking for because its small, the cable comes out of the side, and the output is 1.8A which is greater than the stock Nexus 5 charger. Plus at $3.99 & free shipping for a new charger is not a bad deal. Since this is an OEM Blackberry product the quality is excellent. Cable is around 7ft long.
Bought me two of them, one for the office and one for home.
Will post my results as soon as I receive the charger. Will test how much current the Nexus 5 can pull.

Won't phones and batteries only pull the number of amps they are designed to pull? I didn't think it mattered how many amps a charger could proveide as long as it has enough?

I had tablets chargers that I would use on my Nexus 4 and the phone would charge a lot faster than the stock charger that came with it. I'll do some testing and will report my conclusion once I receive it.
The Galaxy S4 charger works great and really fast.
Meh, the stock charger is 1.2A so that's what I figure the fastest it will charge.
I had an SGS3 and using my dad's Note 2's 2A charger, I was still only drawing out 1A, which is what the SGS3's charger came with.
The Nexus 5 comes with a 1.2 amp charger. I HIGHLY doubt it's actually capable of charging any faster than that (it'd be a lot of heat for such a small device).
Charging amperage is specified by the device not the charger. Value on a charger is the maximum amperage it is able to produce. This means that Nexus 4 or 5 will not get more than 1.2A even from a 2A charger.
If the phone is designed to charge at 1.2A, it will charge at 1.2A max. HOWEVER, not all chargers are 100% efficient. That means your phone may not charge at a constant 1.2A through the stock charger if it is not 100% efficient. That is why you notice faster charging speeds using a 2A charger.
If you don't believe me, get an app like battery monitor widget and look at the power input when you are charging.
This is what I use: http://www.amazon.com/Anker®-Dual-Port-Charger-Samsung-Motorola/dp/B00B8L36A6
Anker is a very good brand

My Nexus 5 charges quickly with the charger that it came with. It is 1.2A. I purchased a new car charger that is also 1.2A now. It seems to work well.

I actually just got my nexus 5 today so I can't comment on the included charger. I was talking about my old galaxy note and htc desire. There was a site that reviewed the efficiency of chargers but I forgot the name of the site.
I use my Nexus 7 charger (2A) and it charges way faster than the stock. They are only $15 on amazon too.
My HP chrome book has a charger rated at 3 amps. Charges the phone crazy fast. I remember seeing these threads and how people said it doesn't matter what the output is blah blah blah. It works. I just wonder what effect it has on the battery? I think its supposed to last longer if you charge it slowly correct?
I use nexus 7 charger. Takes around 15 min to fully charge at 70 percent

Everyone is saying "its faster" but nobody has bothered to mention what faster is.
From 15%, I saw 100% charge in just 2 hours with Qi so I think these phones charge fast in general since Qi is only 1 am output.
If we could stick to real #s going forward then this thread would have some value.
First establishing some baselines with stock charger is essential. Also remember only some fuel gauges support actual current measuring and many apps attempt to calculate current by looking at voltage over time.

Thanks...since I left my N5 charger in a hotel (!) I was having trouble finding a replacement 1.2a charger. So gave up that hunt and just got the Nexus 7 charger on Amazon.

We don't need no stinkin' science in here!
A lot of people just assume their phone is charging faster because they're using a faster charger. Placebo at work.
Folks, if you want to properly determine whether a charger over 1.2 amps is worthwhile you need to do a proper test and remove all the variables:
1. Put the phone in airplane mode and shut down all apps and services. Best if you do this from a clean factory reset so the tests are on equal footing. Any apps using the phone will draw on the battery and influence the test negatively for that charger.
2. Up to 15 minute charging variances are normal. It's a chemical reaction inside of the battery, it's not going to be that consistent.
3. Make sure to charge from the exact same percentage level.
4. REPEAT THE TEST at least 3 times. If the test shows dramatic outliers, perform extra tests and make sure the test is consistent.
Does that sound like a lot of work? Yeah, but it's the only way you can actually make an assertion that one phone charger is faster than another.

No. This is exactly what I'm talking about. I charge my phone all the time. And the second I used this charger and consistently from then on the phones charges about 1/3 faster. I really don't care what is "supposed" to happen. It just works. I get my charger back on Friday and I will prove it. The battery usage shows a giant spike. Upwards compared to the more gradual spike with the stock charger. My Google edition HTC one used to barely charge while playing games with the stock charger and now it charges as fast as stock when I wasn't even using it.

The HTC One's stock charger was only 1 amp, not 1.2 amps. It was clearly capable of charging faster, this phone not so much.

I was actually using the 1.2a charger from my nexus 4 as the "stock" charger. For the same reason, I know more is better.
lg g2 charger works really well for me

Charging The 10.1

I lost the original charger to my 10.1 2014 Edition and I've had problems ever since. Earlier this week I thought I would order a Limefuel 24W 4.8A dual port rapid charger. I thought to myself: Hey I can untick Power saving and have all my needed apps running. Even using a root mod to run 4 way multitasking. Yet it's still sucking up more juice than the charger is spitting out. Am I doing something wrong or did I get a faulty unit from China? This was NEVER a problem when using the Damn Samsung charger along with the foreign adapter dongle it shipped with. I thought getting one so powerful would charge it even faster.
Maybe I should just ship it back and get an official unit from Samsung? Although I don't see how getting less energy will make the tablet charge any better

4.8 amp should do the trick. Could be a fake unit. Is it heavy? 4.8 amp is pretty much, so it should be as big as a lap top charger.
But remember , a cheap usb cable may also be the problem. Try a short one of good quality.
Edit.Just tried a 1.2 amp Nexus 5 charger on my P605. Charging good on full brightness.
Thanks

The charging circuitry and s/w on the device determine charging speed. Do a search. Someone posted the different charging amperages using the stock charge and Apple and HTC chargers and USB cables. The device detected the latter and charged at about half of the former.

Yes thats obvious and i doesnt even need to " do a search ".
The problem was it wouldnt charge at all.
Thanks

Does the p600 also not charge correctly with a non samsung charger? I remember my p1000 requiring an adapter that had a resistor between two connections to charge correctly at a laptop or different charger.
