Tab3 7.0 does not charge with some chargers

Hi,
i have just tried to charge my Tab3 7.0 with the chragers i have available to charge my Samsung Note II and Ipad 2.
Both Note 2 and Ipad can be charged with Apple charger and a chinese charger with 4 USB ports. The Tab 3 cannot
be charged with those, one has to use the charger which came with the tab.
Both the Apple as well the chinese charger supply 2A so it should also be enough for the Tab 3.
Any hints on that ? Is the Tab3 somehow detecting the type of charger ? (i dont think so)...
It is also not the maximum amps as only the required current (which is lesser than maximum) is drawn ...
Regards
Joachim

Mine charges on the charger from my galaxy s3 which is a 1a charger. I have several others I can try I'll post later.

Mine wont charge when i connect it to the pc, but all my normal charger can charge it. Wery strange..

yeah its strange. The Apple charger is also 2A. and doesnt charge my tab 3..

Mine does not charge with my computer when I plug it at first. BUT
if I go to my MB software (ASUS Sabertooth Z77) there is this FAST USB charging option that once enabled recognizes my TAB and the TAB itself starts charging

That obviously just helps for charging from PC via USB, but most of us have AC chargers with us.

And I was talking about the user that said that he could not charge his TAB from PC.

Hi I was wondering if u ever found out why the tab 3 wouldn't charge with other chargers. I have my note 2 charger and didn't work and I bought a cheap charger on ebay and was crap, didn't charge. Do I have to buy the original cable to make it charge?

I will try is maybe the input voltage since the stock charger is 2000mAh. I will try with a 7th charger I've laying around somewhere

1> Few Phones has support for USB charging via a PC. TAB 3 has no support for USB charging.
It does charge very very slowly if u dont use it for a long time while being connected to the USB port.
2> There may be some +- voltage problem with non stock chargers. Its actually not recommended to charge with non stock chargers. Damages the battery.

Hi
I charge My Tab3 with the note2 charger 2 amp. normally.
It take 2.5 hrs tobe fully charged ...
Its stock charger 1 amp take more than 4 hrs.
thx

[Q] Why AC charging becomes USB charging? HELP ME Please!

I always use a HTC usb cable and iPad charger for my note 2 and they work perfectly.
But today when I use them to charge my note 2, I find it charging very slowly.
I check the batter status and find it is USB charging while I use the wall charger.
I plug it out and plug in again , the problem remains.
Resolution: When I restart my Note 2 and use another cable , it turns back to AC cable.
But I don't know which one is faulty? My phone or my cable?
My phone: stand by for 17 days and I didn't charge it cuz I only use this to answer phone calls.
My cable: no physical damage and use perfectly before, though I use it with other devices.
what's more: After I use another USB cable , I try the previous one again and it works well ...
I don't know why.
Is it happening to you guys as well? Is it gonna harm my note 2?

P605 Charging Issues - Voltage?

I've had some trouble charging my new tablet.
When I first received the tablet, I plugged it in to the supplied cable and allowed it to charge to 100%.
I used it for a day to run the battery down.
I then left it plugged in to the computer with a standard cable for 11 hrs.
It appears that it didnt charge at all.
Now I drove all the way back to my office to test it again with the factory supplied cable and it does appear to be charging slowly but it is totally discharged.
I've experienced intermittent issues with charging. Seems like it prefers but doesnt require the samsung charger/cable. Are the voltages and everything the same?

Yeah, seems like it wont charge on a usb port. Only seems to rocognize the supplied samsumg charger...

Do you see that the battery icon has a red X over it when you have it plugged into the computers USB port. The tablet needs the power that the supplied Samsung charger puts out to charge that big battery.
On page 9 of the users manual it says "Note: You cannot charge the battery using the USB cable and
your PC"
.

so is it just a 2A usb charger?

When it's got the red cross over the battery symbol (when it's plugged into a computer USB or car charger etc) it does still charge, but very slowly. Probably only with the screen off.

It charges with any standard charger. I use non-samsung charger and it charges fine, in fact I have not removed the original charger from the box.
As with USB it does charge but really slowly, while it shows not charging.

I believe that a standard USB is 1A and the note 2014 is 2A. Can anyone confirm?

Yes, this is correct, my standard Galaxy S4 is 1A, however a computer may put out even less than this.

No. Standard USB 2 port supplies 0.5A. USB 3 port will supply like 1.5A or less. As for USB 2, you may install (if motherboard supports it) ASUS Ai Charger so that it supplies 1A.
I have gigabyte mb and it has its own driver to over supply usb 2 current. With that I have about %6/hour charging rate if screen is off. Using Samsung own charge, I got about %24/hour.
PS: Look like my desk usb 2 port supplies .5A only (%6x4=%24).

I think you're right. I'm using a 2.1A CostCo Charger and it seems to be charging the 2014 P-605 perfectly.

Not to be rude, but what you wrote here makes no sense to me .

i got the charging issue also, with original charger 2A, original USB cable
checking with galaxy current, value at 900mA

my tablet charges perfectly with original charger and cable but using every standard usb charger (2A and 700mA) it charges but the "connection" is unstable: it's like usb is connecting and disconnecting repeatedly.
I've checked every connection, using the same charger and cable with another phone the connection is stable.
Anyone with the same issue?

[Q] New Note 8 not charging via PC USB

Hi Guys,
I'm just wondering if my unit is defective or it's really the case for Galaxy Note 8's. My tablet charges just fine when using the wall charger, but when I connect it to my PC, it won't charge at all. I've tried different cables that I use for my phone and other gadgets, but none of them will work.
Is there a way for me to make it charge via USB?

Mine also says not charging when its plugged to the PC, its because the USB ports supposedly don't give enought current to charge the tablet, but i once left it connected overnight while transfering my MP3 collection and in the morning the tablet was 100% charged, so i think even if it says is not charging, it charges but ultra slow, even slower than a cell phone.

USB ports on a PC does not put out enough voltage to charge the tab. Like said above, if it does, it will take forever. Look on the back of your wall charger. It should say 10v. USB ports typically put out only 5v. If you look on the back of a phone charger, it should be 5v.

It's not the volts, it's the amps. Your charger provides 2A. A typical USB port provides 0.5A. But in any case, you'll not be able to charge this device from a computer USB port. It's not a fault in the device.

That explains it then. Thanks guys :laugh:

Hmmm... I alway charge my note 8.0 thru my pc usb.
It charges on my pc and lap top.
If you want to be sure just let is sit for an hour and see if the % went up.
Doesnt charge fast but charges in an evening from 60 to 100%

Perhaps it doesn't charge while the screen is on, because the power drain exceeds the charge rate? There would be no way to see it change to "charging" because the screen must be off for that to happen... Just some speculation

I have a HP Envy M6 laptop that I use to charge my Note 8. It only charges on the port closest to the battery. The only USB 2.0 port out of 3 other USB 3.0 ports which is odd because they say USB 3.0 ports give out more power.
I have tried charging it with another HP laptop that has the same USB setup but it doesnt charge in any one of the ports, 2.0 or 3.0.
I guess it just depends on the PC you're charging it with.

Can charge.
hi,
We can charge note 8, if the note is switched off and connected to a PCvia USB

Normally Note 8.0 can not charge with pc usb port or car usb port because AC current of them too low only 0.5A (minimum AC current of charging require should be 1A)
Samsung Tablet stock charger is 2.1A (Note 8.0 device allows 1.8A)

[Q] External Battery with KitKat?

Since most third party chargers don't work anymore with the KitKat update, did anyone try an external battery?

All chargers works, just depends on cable and not chargers or kitkat. You get faster(slwoer charging depends on charger and quality of the cable.
For u question, I used Trent 11000 mah external battery pack, 5V 1Amp and with 3rd part usb cable, that are only for charging, without "data pins". It charging at 500 mah when screen is on, screen off at 930-980 mah and working as normal.
I dont know where u get that kitkat have anything to do with 3rd part chargers doesnt works.

Well my third party chargers stop charging when the screen turns off. Even if I use the USB cable that came with the Note. However, old chargers of HTC or Motorola phones do work with any USB cable. And I have read this from several other users as well.
I'm on stock 4.4.2 with stock recovery. What recovery/kernel/ROM do you use?

I only use third party chargers and cables and have never had a problem.

The problem is Samsungs OEMs usb cable. I found it kinda weird, probably Samsungs have some kinda "handshake" with data pins and I got few of them from old Note 1/2/2014 and somehow it doesnt charge mine old Note 2 anylonger.
I got 4 of Samsunsg OEMs USB cables that comes along with Note 1/2/2014/EED100 (Desktop chagerstand) and I dont know anylonger which one is for each device. If I use wrong Samsungs usb cable, it charge mine Note 2 very slow, battery also drops while charging and I got to pick right usb cable for it to charge normal.
Now I just use this usb cable to charge mine Note 2014, too lazy to swap cable until find correct one and it works fine with any charger.

I tried using the Note charger with different USB cables and it works. Using third party chargers with Note cable does not work, but using HTC/Motorola chargers with any cable does. So I think the problem is with the charger, not the cable. Are you sure you used the Note charger with diferent cables and it didn't work?
Using a 1.0A charger charges the device obviuosly slower but the third party chargers (also 1.0A) stop when the screen is off or the device is powered down.

Alright, I'm now officially out of ideas why this only affects some devices. Would you mind telling me what model you have?

SM-P600

Might be it's a bug in the 605 ROM/kernel. Or maybe related to the snapdragon 800 chip. Maybe Samsung screwed up some drivers, intentionally or not.

If anyone is having charge issues, change your cables. There's nothing special about a "Samsung" cable, but there's a lot of cheap cables out there that have enough voltage drop on them that they won't allow adequate charging. Also, make sure your charger is doing "AC" charging, not "USB" charging- the Note won't draw more than 500mA from USB charging and you may either experience slow charging or none at all if you're using it.
I'm running a P607T (US T-Mobile) model with the German P605 ROM (which should rule out "locale" differences), and my Note charges from any third-party charger I have and/or my Gorilla Gadgets charger battery just fine, whether screen is on or off.

Like I said before, my third party charger stops charging when the screen turns off, even if I use the cable that came with the Note. In settings under battery it says "charging - AC" but still.
It may very well be that these chargers are too "cheap".

The Samsung cable misses one of the two ground connectors. This method was used for devices with mini (!) usb to put them either in power or data transfer mode, depending on the cable used.
However, the Note don't care, I charge it with a 5pin-cable.
The charger should be fully Android - and Apple compatible, as the Note most likely checks for Ipad-compatible signals on the data lines for 2A support.

The USB Port of the P600 is really weird.....I`m searching a long time for a solution to use USB and charging at the same time, and I`m testing a lot of dockingg Stations for this.....thats really strange.....the Multimedia Dock, made for the Note 2, works with the Note 3, without Problems, alll Ports are working....but P600 doesnt accept it as any docking stations, it do absolutely NOTHING, if you put it in.....with the new desktop dock (without usb) both devices will accept it as an "Docking Station"...other Adapters, like Hama, with SD Card Reader, USB and micro USB, will accept as an USB connector, all works, but not charging......but now, the LAN to USB Adapter from Samsung for the PRO Tab Series, wich have 2 x USB, LAN and Charging Inputs, works fine, except the LAN Port......think, there no drivers there at P600.....The USB Port is not same pinned as the Note 3, and also not same as the Note 10.1 and other older Tabs.......maybe it`s same pinned as the PRO Series.....but not sure......
