Hi i have a At&t Samsung galaxy note i717 in white on stock rom flashed with tmobile 4g and using tmobile sim card. i have Clockworkmod latest one and superuser. My notes charging time is extremely slow. I leave it on the charger for 2 hours and it is only at 12% and for it to be 100% i have to leave it over night. like 12 hours. no water damage. never dropped. is there a way to fix it by software or something? please help. i am running 2.3.6 Kernal 2.6.35.11 build gingerbread.ucla1
Use the stock charger and cable. The ones that came with the phone.

I have the same problem but nobody can help me! (except mine is only when I'm using a usb extension cable)
The Note is near tablet in power draw and needs a "fast charge" charger which basically means that the data pins on the cable are shorted to tell the phone it's a wall charger. The stock charger has this and some aftermarket chargers. As far as the extension not working I would bet that the added length adds too much resistance and the phone doesn't see it as shorted anymore, you may be able to make it work with a higher quality cable.

I've tried 3 different USB extension cables... I just ordered a single 6 foot charging cable for the i717 from eBay so we shall see!

Hello all,
Recently purchased a Galaxy S II coming from the first one, liking it alot.
Just wondering, does anyone know if Samsung modified the charger as they did with the original?
I'm not sure on the specifics of what they did, something along the lines of shorting out the data lines on the USB which would let the phone know it's a official charger and let it charge at full speed.
TL;DR can I use any USB charger to charge at full speed?
Thanks,
Spectre
My other android phone chargers (the one I have from my HTC Hero) charge as fast as the original actually!

You could use ANY Micro USB charger connector. However if you use a USB cable, it won't do at full speed charging.
The stock charger only outputs 700mA so with a stock kernel that lets the phone draw more (Its capped to like 650mA), upto 1A and a 1A charger it will charge a lot faster.
Gets a bit hotter while doing it though, nothing to be to worried about.
YMMV/not my fault if it explodes/etc
I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.
Hello,
Can someone please help me out. When I charge my phone using the wall connector (the one which came in the box), it charges REALLY slowly. Like 5-10 percent an hour. Regardless of that, the AC power shows up as connected to USB as you can see in the attachment. Something as simple as texting during charging will drain its battery. Does anyone know what's wrong? It was fine before I flashed a new rom. Supernexus build 5. Even during it, it was fine. I punched in *#*#4636#*#* code and checked the battery health. Completely fine. When I used my brothers Samsung charger, it charges much faster(he has one of those touch screen/keyboard android Samsung phones). Someone please help?

Get rid of the rubbish Samsung supplied charger and use an old S1/2 charger, BlackBerry one's work as well, it's a fault with the Samsung supplied unit.
My phone doesnt seem to charge.
Ive replaced the battery and the chargers (on my third charger this week) and nothing seems to work. Two of the chargers dont seem to be recognised so dont charge the phone at all, the other one does but wouldnt charge the phone even though i was getting a steady charge of 1000mA through it.
Im using Boefla kernel and have 'ignore unstable current' and 'ignore safety margin' both ticked but have tried on my ROMs standard kernel (using Omni) and still getting no increase in battery percentage.
This would all point to the phones USB port not working but i used my girlfriends Lumia charger and surprisingly it charged normally
I have read in one of the other battery threads that a fatter USB cable allows the phone to charge, can this be confirmed? One of the new chargers (one that isnt recognised) ive bought is a 2A charger so i wouldnt have thought that size of the cable would cause a problem?
Any suggestions would be great.
A cheap charger or cable may cause problems, a worn usb port also. More likely to be issues with the plug or socket than the cable core size.

I thought it may have been the cheap charger thing. 2 of them are cheap nasty things but the other one is fine, ive used the same make previously and it worked fine. I thought the USB port myself till it charged using the Lumia charger.
Looks like im gonna have to buy a Samsung charger and see what happens.
My wife has a 3 month old Galaxy Mega 6.3 and it will not charge correctly. It will not change when it's on enough to keep it on. Last night I had her charge it while it was off and after 12 hours it was only at 48%. We have tried new chargers, new cords, taking the battery out for a while, nothing is working. Any ideas? It's completely stock, no root.
Hi .. make sure that your chargers output power is 2.0A don't use chargers with 1.0A or 0.7A output or it will charge slowly .. and try to use a short cable ..shorter is faster .. If this didn't help maybe the problem is with the battery it self buy a new one

Yeah, we used an oem charger and cable and a charger that puts out 5v and all the same charge rate
I think 5v is too much & dangerous for the phone maybe it'll ruin your battery

Hi..the original charger for the mega 6.3 is 5v with a 2.0A charging rate, can you test another battery from a friend to see if it is the battery.
I literally have never seen anyone with a mega besides her lol. My next plan was a new battery, but I didn't think a 3 month old phone should need one yet.

Maybe go to your carrier were you got the phone and explain what has happened and maybe they can give you a new battery or if it is a hardware problem..they can maybe give you a new phone.

She bought it outright unlocked, so I guess we would have to go right to Samsung?

Forsure then try samsung then as the battery should not be hosed yet unless it was a half dud to begin with. .

Hello SumCanadianGuy
To be sure to get fast charge with most Samsung smartphones, you need an original Samsung charger AND a fully connected (4 wire) USB cable.
Charger outputs 5.3 to 5.7V and pin 2 and pin 3 (data pins) are shortened together inside the charger to indicate the phone that he can draw fast charge current.
All my original Samsung wall chargers are rated only 1A. It doesn't mean that they can't output more current for a short time. I get fast charge every time.
If either your charger isn't an original with pins 2 & 3 shortened, or your cable has no data connections, you won't ever get fast charge. By example, if you try to use a powerful 2A or more iPad charger with your Mega, you won't get fast charge, just because the other world doesn't conform to USB
If you can, try an original Samsung wall charger with an original Samsung usb to micro usb cable.
Hope this helps
I have same problem with my Samsubg Galaxy Mega 6.3
I tried everything (change battery, cable, charger) but nothing help.
Charging is slow but during all night it could charge to almoat 100%
It only could be hardware failure...
If you want to see power of charging install app Galaxy Charging Current Lite.
Power of charging should be 1900 mA and I could get only 300 mA...
