[Q] Galaxy Mega 6.3 EXTREMELY slow charging. - Samsung Galaxy Mega

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?

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...

Galaxy S3 Charging Very Slow

In about two hours of charging I went from 8% to 41%. Is anyone else experienceing this issue? I'm using all the cords and plugs given to me for the wall.
I don't have the SGS3 (yet), but my guess is that the battery is so large it takes longer to charge. Keep in mind that it's a 2100MaH battery. Depending on the power that the charger puts out, it could take longer to charge this battery than another phone.
Mine charges fairly quick with stock items.

Mine went from 2% to Full 100% in a little over 2 hours on the stock Samsung charger.. I'm going to cycle mine 3 or 4 times being that it's new obviously.

So would you agree something is wrong with my phone?
I agree, the first few cycles might not be too accurate. If you want a faster charger get the HP Touchpad charger, it has 2 amps where as the Samsung one is .75 amps of charging. only $5 on hp website. that's what I use.

Monoprice sells a 2.1 amp 4 usb wall charger as well but it is not as cheap nor do they have free shipping *although atleast in CA I can get a flat rate of 25lbs and under for ~$5 shipping.*
I'm surprised no one has posted the correct answer to this yet. The wall charger Samsung has decided to include with the S3 NA is complete and utter crap. I believe it is .15amp draw. You need to immediately throw it in the trash and buy a new one. It is not a problem with your phone.

while I like Monoprice, the HP OEM charger is better in my opinion. its solid built and portable too.
I use the Blackberry Premium charger works well with my S3 and is only like $15 or so on Amazon.
Before I rooted and calibrated the battery. My phone took 3hrs 20min to fully charge on stock 1A charger.

My Samsung Charger that came with the phone is 1Amp...charges the device fine. I don't think the 2Amps will make a difference if the charging chip doesn't support it (not saying it doesn't but the SGSII would only charge at 650maH no matter what charger you put it on)
Mine's charging insanely fast with the stock cable. Not sure if it's a good thing because battery life isn't all that amazing on my phone so far.

doesn't that mean each USB port is 0.5 amps?
Anyways if I'm not wrong the amps has to do with what it can supply. Whether the device tries to draw that much power is up to the device.
The stock charger is 5V 1amp.
Even if you use a 2 amp charger it will likely only draw one amp.
Even if it does draw 2 amps that would mean you are increasing the heat associated with more current. Heat is the worst thing for battery life. Its always better to do slow charge unless you're in a hurry. Your battery will last a lot longer that way. Having said that, I think 1 amp is a good compromise for speed and heat.
p.s. computers output 0.5amps per USB slot by default specifications.

Faster Charging 2amp Touchpad Charger for $4.99

I noticed a lot of people want a fast charger for the Note. This charger is for the Touchpad. I have this and it works really well. It charges faster than the OEM charger that came with the Note.
Not to mention, it is on sale right now for less than $5. Go grab one. From past experience, I used this at 15% battery life and charged for an hour and I was back over to 80%.:victory:

Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.
Thank you, getting one!
This have been discussed hundreds time before....
That 1amp is the output of the charger which forwards the current to kernel of the device... NOTE can only intake 1 amp current... ( remove your battery and read the dam sticker :thumbup
Even though you will supply 2 3 4 5 amp... The maximum in would be 1 amp ONLY...
SECONDLY, micro usb cables have a restriction of carrying current... They cannot pass more than 1 amp current successfully... Therefore galaxy tab series does not come with micro usb slots....
Lastly my recommendation would be NOT to waste money on any other chargers...

It has been discussed, but it DOES charge faster than a conventional 1amp charger. If you don't have the charger and have nothing to compare with, then I don't think you can say it does not work.
Go check FCC about the charge. Also, the cables provided DOES carry a 2amp charge. Our note can handle fast charging but throttles down to a slower charging rate after 80%.
having a micro usb slot or not have a micro usb slot has nothing to do with the current it can handle.
Ipads and Iphones have the same connector but yet one has a 1amp charger and the other a 2amp charger.

You don't have to get your panties in a twist. Rather than just read forums and assume the worst of everything try it for yourself. I've tried both and it is faster. Just trying to help my fellow Note users to get the best out of their phones.

As an HP TouchPad owner, I can confirm that the cable provided with the charger are 'special'. My TP will not charge with any other MicroUSB cable connected to the official charger, the same cables which won't charge the TP will charge the Note. (I also own the HP touchstone dock, which the TP spends most of it's life sitting on.)

I have four different wall chargers, including two of this HP barrel adapter (one that came with the TouchPad, one that came with the Touchstone). With the supplied cable, it does charge the TouchPad very quickly. From webOS, the net charge rate is about 1.6 A with the screen on, so probably close to 2 A coming out the USB port.
However, when you plug a Note into this charger, the Note will still only draw 1 A. I have other AC chargers that are also able to supply 1 A to the Note, so in that respect this HP charger isn't anything special. However, it is only $5, which is a good deal.

I've found that the microUSB cable that comes with the Note, when paired with the HP TouchPad's AC charger, will supply 2 A. At least, that's what the OS reports: /sys/devices/platform/usb_gadget/current-mA shows "2000". Plugging the TouchPad into the Note's AC charger shows a value of "900". Plugging it into my laptop's USB port drops that value down to "500", as expected.
I bought two a week ago off Amazon for $10 each. $5 each with free shipping is a steal. I picked up three more. Thanks for posting this deal. I get 1A charging with either the stock charger or TP charger. I like to have a few extra chargers to sprinkle around at home or work (for my Note and the other devices I own that charge off USB.... including a TP).

When you charge your phone using this HP microUSB cable, do you have issue with NO DEEP SLEEP when unplugging the Note from the charger?
There has been issues reported in XDA where, depending on the USB cables used to charge the Note (connected to computer OR power charger), if you unplug the Note, it will not go DEEP SLEEP, causing significant power drain.
This does NOT happen when the Note is charged using the cable that came with the Note.
Download Current Widget from the play store. Add widget to home screen and you will realize that your phone is not charging any more than 1 amp as designed.
Try the usb out from your pc and you will see about half an amp.

I charge my Note overnight using my Touchpad's MicroUSB cable plugged into the Samsung charger, and I don't experience any difference in power drain.
Where is that post from the guy who put all these petty arguments to rest with scientific tests of all the various options and results??
Good lord people it's a charger for a phone .. no need to get so heated!
(unlike my stock charger.. which gets very heated!)
great price!!!
ordered 3 of them
the price is way cheaper than just a single micro usb cable shipped from other stores
i have 3 already
1 at work, 2 for home.
definitely faster than OEM. I charge overnight, no issues. had for around 5-6 months now. and i can use the phone while charging.
fact is that it DOES charge faster.
i recommend it
WOW***
Great price I bought 2!

I have the same prob. Charged about 7% in 30 mins (using the supplied charger). Charges fine when I use my N7 charger though. I'm gonna have to check the charger when I get home.
Just for the hell of it, here is my how my charge is going right now:
7% - plugged in at 3:22
21% - 3:31
33% - 3:42
44% - 3:52
57% - 4:04
83% - 4:28
For what its worth I don't have this issue with charging - s4 charges comparable to s3 HOWEVER i am not using stock charging that came with the box, I am using cables i have had from before and sometimes even use the USB to wall plugs from Apple and/or BB or whatever I have had lying around - seems to work well.
With a 5V 2 amp charger it goes like a bat out of he'll, using my thunderbolt's 5V 1 amp charger it's quite slow.
Sent from my SCH-I545 using xda premium
i have noticed that having it plugged into either a car charger or a computer, it does NOT charge very quickly... not to the point where it is annoying but, slow enough to notice a difference...
If i take the cable from the box and plug it into my USB hub (it has it's own power source also) if im using it for much other then file transfers i can still lose power off battery. It just seems to slow the battery drain instead of just charging slower then plugged into the wall with the 5V 2amp plug. Now obviously if I'm not doing much with the phone while on the USB it will charge but much slower then the wall charging

Same here...on stock charger my phone charges v3ry quickly. Are you rooted with special ROM? Are you using non samsung charger?
Sent from my SCH-I545 using Tapatalk 2
Ok, there's something else going on here. Maybe its software related.
My S4 will only charge fast on the supplied charger. The cable doesn't seem to matter; I tested a bunch of them. I have an assortment of other 2A chargers and none do better then barely keeping up with power useage; hardly any charging at all. Again, the usb cord doesn't seem to make any difference.
Now, I've read mention of a "fast charge" feature that the kernel developers are "turning on". I haven't found a good explanation of what exactly that means but it appears to me that Samsung tried to make the device only charge at the full rate using their chargers and at a minimal trickle charge rate for all others even if they are capable of the full 2A output.
Then there is the problem of buying extra Samsung chargers since there appear to be a lot of knock-offs that will not get the phone to charge at full rate.
What a stupid thing to be such a PITA.
Anyone have any solid info on this?
just about every samsumg device either needs a kernel hack or an adapter to get fast charge off of a non-samsung charger. you can grab a few of these:
http://dx.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
and use them with just about any 2amp charger with no problems on my old galaxy tablets or my galaxy note and nexus getting fast charge(nexus even charges faster on the 2amp - hope i don't blow it up!).
Fast charge from my understanding is just turning off the data connection when plugged into a computer. This allows for higher usb charge rates, it also helps certain wireless charging setups. I am coming from a gnex where this was the terminology, I assume it's similar. Fast charge shouldn't do much for you if you are having trouble with 2amp chargers, but maybe in this case Samsung limits through put when it doesn't recognize the charging unit? If fast charge tweaks somehow disable this, then I guess it's possible you would enjoy increase in charge rate though I have no verification on that.

Well, I have to discount my own theory. I have some off-brand adapter and cable to charge in my car that works great.
I sure would like to know what's going on with the chargers in my house.

There's a problem with semantics going on. Fast charge is exactly what you're used to it being on the GN. What's being referenced here is quick charge, a feature of later Snapdragon SoC's.
Sent from my Nexus 7 using Tapatalk HD
fast charging is rapid charge where near full power is transferred. in the gn2, gnote 10.1, gnex, and gtab10.1 the max i got was ~1600mA with all my 2.1A chargers including the samsung charger. the rapid charge continues to 90% and then switches to trickle - anywhere from 400-900mA til 100%. without the adapter you're stuck at trickle, even at under 90%. some chargers seem to have it built in to rapid charge,but most don't.
i've never gotten a full 2100mA from any charger yet.
you can find schematics on how to build your own adapter in one of these samsung boards. i think there was a very detailed one in the gnote10.1 forum.

Hi,
I did not understood your question. is your question is "is 3-4 hours is normal charge time for your phone?
I have the 9205 MEGA 6.3 and it looks like this is about the right charging time with the original power supply (Charger).
I check on the samsung USB charger and this is a 5v / 250Ma chargeur. I replaced the charger by a old USB Blackerry charger 5v / 500Ma and it is charging now in less than 3 hours.
Did somone try a 1A charger to see if it is faster??
Thank you.
use a samsung charger
When u use a samsung charger with it. Charging is faster. I for one use the plug alone with by blackberry usb (cos its longer) but if I use any other charger. .. thats some pretty slow charging id be experiencing so I go everywhere with the charger in my backpack

Even though you can try to use that battery with wireless charging it won't fix your slow charging rate. Wireless charging goes max to 0.6 A (600 ma) when it comes to charging. So it's 1/3 the speed of your regular wall socket charger.

When I say slow charging I mean it comes up on my screen saying charge it with the cards given. It charges about 30% in about 9-10 hours.

Something is wrong with your charger or cable then. My ZL charged from ~78%-100% in about an hour last night. The plug adapter that came with the phone and a USB cable I've used for a while, from a Nook I think. Wireless will be VERY slow. It's fine for topping off, but if you drain it down you will want to use a wired charger. You can use a wireless charger with the ZL, there's some info in one of the threads talking about what you need to order. You can't use the contacts on the back of the phone for it, you need to use one of the low profile USB plug type.
If you want fast charging you need to use the adapter that came with your phone, or another known good adapter, and a good quality USB cable. It doesn't have to be USB3, a USB2 cable will work fine, but it needs to be good quality. Monoprice is a good place for inexpensive, but good quality cables.
If you are connecting to a computer USB port, you will charge slow unless it's a USB3 with a USB3 cable.

I've bought a couple chargers on eBay and they said it was OEM, but neither have worked. One was a Motorola and the other was one specifically made for the Note 3, or so it said.

Didn't you get one in the box your phone came in? Try that one. Like batteries, chargers are often fake and don't meet the specs they list.

Try a usb 2.0 cable to charge it.
The little extra part for the 3.0 seems to have gone bad in my phone after only 4 months.
If I charge it with the cable that came with it, I have the results you are saying.
If I charge it with a 3 year old usb 2.0 style charger, it charges fine.
Good luck!
Get a usb voltage/current tester. They are like $10. You can test all your chargers and cords and find the under performers.
My phone with zerolemon charges fast with the original samsung charger, and my Asus t100 charger. Fast being relative, from 20% to full it can take 4 hours or so. I've never timed it 100%

Does your battery seem to die quicker right after you unplug it?

Yes, it drops to 97% straight away. This is because it drains in the background a little as the charger doesn't trickle charge. See this for an explanation http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
