[Q] Q - charging problem - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hello, I'm having a quark with charging my wifi tab 10.1. Perhaps it is my frustration in looking for a reason or just not wanting to accept what I think it is. But I can't seem to find the answer. (I think the problem lies in voltage output)
The problem is this, If I use anything other than the wall plug + usb cable that came with the tab, I get a red mark in the battery, indicating what I am only assuming means that it is not charging.
Have had several HTC and now samsung devices I have plenty of the wall chargers(receptacle for the usb cable). Tab wont charge when plugged into pc either, give the same red indicator.
Thanks to any help

I have the exact same and there doesn't seem to be an option to change it, for as far as I've seen. (And I've browsed through all options at least a dozen times, so either I'm very blind, or it's simply not there.)

I can't charge it using the cable it came with either by USB or by Mains... exact same issue you guys mention

I am not sure if I can provide the exact answer to your question but this is what I have learned. The Tab needs a two amp power source to charge while it is operating. Most USB chargers and ports on computers only put out about .5 amps.
If you power off the Tab and plug it in to a computer USB port, the device shows that it is charging but if it really is, the pace is very slow. I tried to charge mine from the USB port on my laptop after powering off. After two hours of charging, I did not see much if any evidence that the battery level had gone up.
I have not yet found a 2 amp USB car charger that will accept the Samsung power cable but it seems reasonable to me that if you have one of those, you should be able to charge the device in the car. Of course, you could buy the Samsung car charger which I am sure works.

[SOLVED] Atrix will not power on, green light flashes, plugged in and.... nothing!

Went to sleep last night with my Atrix plugged in as I normally have had all my phones, was playing with it right before I went to sleep and everything worked just fine, woke up this morning and the phone will not power on!
First tried to power it on unplugged and the green light flashed for 2 seconds, and nothing happened. Okay, weird, but I'll go with it. Plugged it in, and the green light stays on now until I press the power button! Once pressed, it flashes off, flashes on for 2 seconds and stays off. Nice. I thought the green light meant it was fully charged - when I woke up this morning, it had no green light on, but it was plugged in just fine all night - grabbed my Jawbone ERA and plugged it in to the charger I had the Atrix connected to and it started charging right away, so I know it works....
Pulled the battery, tried plugging it in and power it on without the battery. Nothing. Tried putting in the battery and plugging it in again to "jump start it" as I had done yesterday when I first got it - apparently you can't just charge the thing when connected to a laptop if the phone is off, it will power on even if you power it off again! Nothing.
What the hell happened in it's sleep? I KNOW rooting it didn't cause sleep death.... This thing doesn't have a custom ROM or any undervoltage adjustments, so why the hell is it acting up??? Damnit, right when I got EVERYTHING set up the way I wanted it too.... can't bring it in to the store and give it up with all my personal stuff on there now, I need this thing to power on to wipe it first!!! I'm leaving it connected to the laptop with the green light on for a while and will see what happens in an hour or so....
EDIT - just searched for and tried to hard reset the phone from this thread, the phone still won't even power on to get to the recovery screen!!!
UPDATE - see below and use the SUPPLIED Moto AC charger or at least one with over 5.0V - NOT a PC and NOT a USB hub!
use the charger that came with the phone. My old HTC ones won't charge the phone for some reason. I bet your battery is just dead.
Did you use the provided charger? I tried plugging my Atrix in to the charger I used for my N1, and found that it did not provide enough current. With the old charger, after the phone died, I had similar symptoms where the green light would flash but phone would not come on. Plugged it in with the Moto provided charger, and 5 minutes later all was good...
I had the same problem. Thought I was gonna have to take it back to the store. I don't know what the problem was but I took the battery out for 5 minutes. Then I plugged it into the wall charger(wouldn't work with PC). I didn't turn it on for 30 min, just left it on the charger. Then I hit the volume rocker and it showed the battery charging symbol which it didn't do before. And then I was able to power it on
Same thing here. I purposely drained my battery on the first use. Plugged the usb cable into the PC and nothing. Same blinking green light with no response. I also thought I'd have to return the phone. Then for S & Gs I plugged it into the wall charger and it came to life. Once I got the battery charged a little bit I plugged it into the PC and it started to charge again. Don't know why, but it worked.
Have been running around the house trying to find valid outlets, and that does indeed appear to be the problem. I found it out the hard way though, should have kept an eye on the thread - used a power outlet instead of a PC USB connection and the screen fired right up! Yes, the phone showed the battery with 0% in it, but at least the screen finally came on!
How I have my phone set up normally is connected to my charging valet on my dresser, connected with a 15 foot USB cable that plugs directly into my desktop. Since the extension is good for just one USB connection, I have that connected to a USB hub and then a MicroUSB cable connects my phone from there. The Captivate, and all the other phones I've ever used, not to mention my Zune and Jawbone ERA, all eat that up and have no issues since the USB hub is powered not by the computer (seven USB cables is just too many for a single PC connection) but by the power outlet in the charging valet. I wonder if the hub is distributing the power requirement for each device and the Atrix needs more than others.
I also figured out that the Moto charger has a 5.1V output on it, as does my Jawbone AC charger. Now I need to start making sure that my each one of my chargers in the cars I own has that same type amount of juice too! You go up 29% in battery capacity and so do the requirements to charge it, huh?
Thanks for all the help, marking this SOLVED....
I used the charger in my bedroom that I've used for the Captivate and others before it and it didn't provide enough juice to charge the Atrix. It quickly switched between charging and not charging. I still had 40% battery showing when I woke up though which was nice. It had been off of charge since 10am yesterday.
Plugged it into an HTC charger and it's fine. The one that didn't work is not a modular charger so the power cord is hard wired to the plug.
Alright, a quick update.... Got the phone charged to 100% while it was off and plugged into the AC outlet with the Moto charger. Put my SIM card back in it - couldn't be without a phone all day! - and fired up the Atrix. Went to Battery Info to see what the status is and while plugged into my USB hub, it says
Battery Status: Discharging
Power plug: USB
....
Battery Voltage: 4124 mV (or 4.124V)

What the hell? Then I went right after that and plugged it into the Moto AC charger, it says:
Battery Status: Full
Power plug: AC

Battery Voltage: 4207 mV (or 4.207V)

Why are POWERED USB hubs and PCs not strong enough to charge the phone? I tried ALL my outlets in my vehicles just now and they ALL show full battery status and plugged into AC! Who screwed this up????

Did you download the PC Charging Drivers that Motorola requires you to have in order to charge via PC and USB cable? If not, look here.

Wait, you have to have specific drivers on the PC so that the phone will allow a power cable (let's not even worry about it being a USB cable for a second) to charge the phone properly? I have the Motorola Media Link software installed, and that has a ton of drivers on it, that wasn't enough? MORE drivers are required to charge a cell phone? This is madness!
Sorry about the necromancy, but had this problem myself but it is NOT due to a lack of voltage. Thought I'd actually solve this, the problem is CURRENT.
USB2 ports will only ever supply 500ma which simply isn't enough to charge the atrix when it's dead. USB2 powered hubs won't supply any more than this either to meet the USB2 spec. The fact that the AC adapter works is because they tend to have a higher output current in the region of 1-2 amps (you may notice the phone, or any other device for that matter, charges faster with AC adapters for this reason).
On a similar note, cheap car chargers only output 500ma. I know with my desire I can have it plugged in and it charges, but if I use GPS it actually draws more current than it can charge at resulting in the battery draining (albeit, slowly).
So, make sure you have a higher current AC/Car charger, or alternatively, plug it into a USB3 port to charge as USB3 spec allows 900ma (some mobos output up to 1A) which is enough to charge the Atrix.

Not sure about this..... It's been about a year since I got all my USB3.0 gear, and I was super excited about it because I thought that my phone would charge ridiculously fast because of the added output, but I remember reading that 3.0 uses extra pins and those pins account for the added voltage and bandwidth of the cable - we don't have those extra pins when you step down from 3.0 to 2.0, so we lose the ability to charge devices faster as a result. I don't know if I actually proved that theory, but after I read up enough on it, I thought I just didn't have to with that knowledge..... again, correct me if I'm wrong, I've got a lot of 3.0 gear here!!!

There are indeed extra pins in the USB3 standard but these are to transmit data only. The original USB2 data pins are only there for legacy support and USB3 transmissions use the extra lines. There's still only the 1 VBUS pin which supplies the +5V power. There's also no harm in offering higher current on the connection as a device will only ever draw as much current as it needs until it tops out the supplier, not the other way round
EDIT: Another solution could be to use a splitter cable (common with 2.5" drives)so you can draw from 2 ports, but with a micro connector. I've never actually seen one with USB micro but a quick look on ebay says they do exist

atrix 4g not coming on
Is there any real fix to this issue i have search high and low and all i am seeing people talking about the battery id dead ... i have two battery that is fully charger and the phone still not coming up.
Hi all, sorry that im posting after two years ago but i am facing exactly the same problem, but i plugged it in my USB port, wich i think its a usb2, and i got the screen on but the cellphone did not say charging instead of that was connect your charger, and it was lower than 3% then it turned off. What can it be a solution??
None of the avobe solutions worked?
Which rom/kernel are you using?
I too have this same issue. My Atrix won't come on. I have 2 of the same phone. I tried the charger and cable from both phones. Neither work. When I first plug it it, the green light comes on for a few seconds then it goes out. I even opened the phone and removed the battery. Used a voltage tested and found my battery has 3.7 volts. Thats almost 100% charge. So it not a problem of power. I plugged the phone to my computer and same green light for a few seconds then gone. Won't do anything. No battery display or anything. I even did the simulated battery removal procedure. Didn't work. Is there anything else I can try? Can't get to recovery mode without display unless someone has a fix for that?

[Q] Atrix strange charging and USB issues

Hi all
I have strange charging and USB issues with my Atrix.
when the phone is on it will not recognize the USB connection, no USB notification and will not charge ( PC or Wall). its seams that the usb port is completely dead!
when the phone is off, connecting the wall charger or the usb, green light on the phone and the phone will boot. still no charging.
in RSD light mode, the usb port is fine ! even I can flash.
to be more strange, using multimedia dock: the phone will charge as it should no mater the phone off or on !!
now I have stock ROM 2.3.4, I have tried different Chargers and USB cables but nothing changed.
I have searched the forum for similar issue but didn't found one. so if any one have the same issues ....... you are not alone
thanks
i've had weird results with chargers that were weaker than the stock charger that came with the device. i'd say as a good rule of thumb it needs to be able to provide at least 0.85 - 1.0 amps.
I have two motorola stock chargers, one is its original charger and the second is defy's charger. both work fine on the defy but not on the Atrix..
I think you are right. may be the power is the key of the mystery. because the multimedia dock has its own power supply which provides 1.5 Amp. so may be there is a malfunction in the phone hardware (charging ckt.) causing the phone to draw more than rated power from the charger which the stock charger cannot provide!
I have the same issue either! Exactly the same.
It happened like few days ago but I didnt aware that until my battery runs out

Prime won't charge

Hello
My prime was charged a few weeks ago, and i haven't used it in a while so it discharged and turned off.. Now when I try to plug It in, it shows that it is charging, but nothing happens..
It charged for 3 hours, and when I unplug it, it can't turn on.
If I leave it plugged in and turn it on, it shows a screen with low battery icon and turns off immediately.
I can charge the keyboard just fine, the charging led on the keyboard turns green after a while.
It's rooted, but stock rom and have never unlocked it, so no customer recovery..
Hope someone can help me out :/

It sounds like your battery may have died on you.
Are you using the AC charger or the usb charger?
Mine takes a long time on the usb but charges better on ac.
Are you charging them both while docked, if so try undocking and charging them separately.
How old is the battery, Prime now?
The battery is guaranteed for 12 or 24 months also, just check where your serial number is and it will have a 12 or 24 number on the right under your model number.
Also,l check the charging port and make sure no debris or foreign matter has accumulated in it and some of the pins aren't bent.
If none of this works it means you have an internal problem and a different recovery won't help because you still cannot get it charged.
Post back with your results please.

I've tried both charging it through USB from my computer and through the wall charger (original charger and cable).
I've tried charging it both docked and undocked, separate and together.
The Prime is bought about 7 months ago, and i have checked for dust and such in the various parts.
It says "12" below the serial number btw, but i bought it from England (i live in Denmark) though Amazon, so it would be hard for me to return it..
Though there is 1 thing that is bugging me and i'm not sure if it can be the problem.
There is 1 pin that's not aligned with the others on the charger port on the prime itself
Picture to explain: http://i45.tinypic.com/2r4sw7t.jpg
The 2nd pin from the far left is a bit longer inside the device than the others. I've tried to get it out by using a little metal stick (don't know what its called ) but I've been unsuccessful..
The prime obviously gets some sort of connection when i plug it in (though only if i plug it into the wall charger, doesn't happen with USB, which i kinda predicted) and gets enough power to vibrate, then turn on for about 4 seconds to show a big red battery icon (meaning low power) and then turns off..
I've tried to correct the pins on the wall charger so they're more stable and connect better, i've tried putting the wall charger in the freezer for 20min (google'd it as a possible solution, other said it helped them). I currently don't have any other charger or cable that can connect/charge the prime, but i don't think the problem lies with the charger/cable..
I left the dock+prime docked together charging all night and when i woke up, the dock LED was green but it still wasn't able to boot up at all..
Is there anything i can do to reset the Prime? I've tried the little pin hole under the sd card slot, i've tried various combinations of volume up and volume down and power, but i always end up with the screen with the big red battery icon..

I am 90% sure that 2nd pin from the left is your problem. if you cant find a way to pop it back into place or dont know somebody who can do it for you then you should probably rma.

This happened to me because the battery connector inside the device was loose, I had to open up the device up and re-connect it. This time, I've placed some tape to try and make it not fall out again. Maybe the battery is faulty?

Weird charging problem

I have weird problem when charging. If i charge using my docking station, my phone charges real fast. If I take the same cable and power used on the docking station (original Samsung power and cable) then my phone charges 30% for 7 hours with mobile data and wifi turned off. Could you tell me how to fix that?
If I use my brothers power from his S2 I get fast charges as well.
Did my original cable and power go bad? Why does it work fine through the charging station then?
Ok, anybody can give me a hint? Is there something I should try?

99% the problem is usb cable. Ihave the same problem,tried 6,7 usb cables but nothing solved my problem 100%. The best results is with Nokia Lumia charger and usb(for me at least).
Sometimes i need to plug and unplug 2,3, times to get 999mAh.(plug in and out of phone usb,not the outlet.)
insall this and check the current every time you plug the phone. It's pain in the ass but at least i know what to espect .https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en
I get 466 or 999mAh.

S3 charging too slow

Hello all, I have a galaxy s3 I9300, the problem is the charging takes forever to charge ... I tried AC and from laptop. I changed the battery to my other I9305 , and the charging went really fast so it's not a battery problem.
If it's the charging port , can it be fixed ?
Mabye the problem is the cable; try another USB cable to see if there are some difference.
If not mabye yeah, is the charging port.
Try to hard reset
I had the same problem and after multiple headaches, I finally found the answer.
Check all these things out:
- Some background application or service might be draining your battery and thus not letting it charge properly. Go into battery settings and check if everything is normal or there's something disturbing in there.
- Your micro-usb plug has dirt in it. If you can't see anything from the outside, and you're not going to mess anything up, I'd recommend to dissable the phone and have a closer look.
- The most common and most likely problem to be going around is that your cable or power adaptor isn't working as it should. If you are using the stock SIII charger, it has a well known problem and doesn't provide the 1000mAh it should - I have two and both of them give an output of ~100mAh. To check this out, download an app called "Galaxy charging current" (I think you must have root access on your phone for the app to access the charging data). If it's not getting 1000mAh, try changing the cable or the power adaptor.
I hope this helps!
