So my situation is that, using the app Galaxy Charging Current, my current seems to be fluctuating. I got several cables and they were okay for a few weeks and after a while their performance started to degrade even though there was no abuse. The cables would be charging at 1800mA one moment, the next it'll be 1400mA. The values would also change if I plug in and out the cable. Oddly though, using the same cable and charger combo on another phone, the charge would be about 1800mA. I'm thinking that the USB port might be broken because when plugged in, I could wiggle the USB quite a bit. Also, I'm using an original Samsung charger too. Anyone else had any problems like this before? Did changing the USB port helped? I don't really mind changing it, but I rather not spend money on something unless I'm pretty sure.

I have a question for the xda community hopefully you guys can help me out: ok so i have been charging my tab in my car using both the cigarete lighter and ac outlet, but i have noticed that it discharges faster than it charges, for example if i am using the gps while charging the tab the tabs battery will drain. On the other hand if i am charging the tab at home on a regular wall outlet it charges fine. In comparison my samsung galaxy s charges fine in the car via the cigarete lighter. I am using the original charger that came with the tab. Any ideas as to why it drains faster than it charges? Thanks.

The Galaxy Tab USB port is wired slightly differently to other USB ports, which results in only getting a trickle-charge from regular USB cables. You need something like this...
http://cgi.ebay.in/USB-car-wall-charger-adapter-plug-Samsung-Galaxy-TAB-/190522553195
I can't vouch for that particular seller, but I have one of those adaptors and it makes all the difference when plugging into anything USB.
Incidentally, when you say you're using the charger that came with the tablet, are you saying that it came with a car charger? I've not heard of that before.
Check the output of the charger. It should put out 2000mA. It should be written somewhere on the charger.

I had read that the port was wired differently. Thanks for the link into ebay for the charger adapter. For the price, it's worth checking out.
I guess I can give it a try

I brought my 7 home Saturday at 33% charge, plopped down on the couch, plugged it in and started playing. The battery level slowly dropped. The charger WILL charge it, but only when it's idle and it seems slow as hell. I figured a 2A charger would have my Razr Maxx full in no time but in an hour it went from 40% to 50%. After completely draining my Nexus 7 I plugged it in and charged it at idle for 12 hours. When I looked this morning it was at 67%.
I'm assuming the charger is bad. I also have a different cable plugged in to it which I suppose I should try replacing first. But if this thing actually charges that slow I'd rather find out now than keep searching for a problem that doesn't exist.
Is it possible that your cable is an older one and can't handle the higher electric current? I read that this happened to people who used older cable to charge the Retina iPad as well. Don't know whether this is the reason.
The cable is one I got on ebay for $1. Entirely possible that's the problem. I'll try the OE cable tonight.
You should always use what the device shipped with. More than likely, that's the problem.

Well, I can't very well "use" a 3' usb cable. I hope you don't think you should buy $100 hdmi cables, too.
Nope, but most devices don't ship with HDMI cables. I've bought cheap cables online, but if my phone or tablet came with one I surely use it.
I've heard and seen people messing up their devices or having weird problems (like yours) from using a different cable and/or charger plug. So I always use what it came with. So many little nuances .

I definitely need a longer cable. Guess I'll just have to pony up for quality cables instead of these ones that ship from China.

Non-sense. Go to monoprice.com and you can get plenty of dirt-cheap cables that get the job done just fine. It sounds like you're currently using a 2-pin micro-USB instead of a 4-pin. The extra 2 pins are for data, as well as high-power charging for devices that pull more than USB's standard 500mA.

Doh.. I'll start by pulling out the multimeter when I get home. Or maybe just looking before I even bother with that.
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

I think you need a bigger charging maybe the charger is not able to provide the needed ampere.

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.
OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
Hi,
Can anyone recommend a decent USB cable for my sons N7?
Need to get a replacement, but the ones i currently have are not beefy enough to charge properly.

Same problem, can only find pathetic skinny fragile things.
I have used this cable without any probs
AKASA part no AK-CBUB05-10BK
bought from CPC order code CS20881
Try a flat ribbon cable, Amazon Uk have them http://www.amazon.co.uk/s/ref=nb_sb...onics&rh=i:electronics,k:flat micro usb cable Various lengths and colours. I use a standard 1.2mtr blue one that I bought last year.
I'm using Logitech cable for charging (got it with the mouse) and Nokia cable for PC (they are always connected, that's why separate cables), so get one of those.
I've only had problems with 3 years old Samsung cable because it kept falling out (it stays in on my SE phone)
I really doubt beefyness of the cable affects charging though. I charged my tabled on just about any cable I've found laying around in the house with no problems
The reason as to why your charge cannot keep up is most likely due to using a charger with lower amperage (i.e 1amp/1A).
As long as you purchase a 2amp charger and compatible usb cable, then you shouldn't have any more issues with draining the battery faster than it can be charged thanks to the 2amp charge rate.

Thanks for the reply guys, this is using the Asus charger that came with the device, just that the original cable split, so I need a replacement.
Have looked at the cables, might get one of the flat ones as they look good.
Cheers,
Paul.
Just to let you know I bought the flat ones and they fit and work really well.
Thanks for the replys all.

Trick is to get a short a cable as you can. The impedance really effects charging. The difference between my stock and a 6' cable is like a 60% drop.

I'm using the stock 3.0 use cable that came with it, but within the past week or so, my charging times has doubled. Has anyone else had this issue with their phone (Note 3, AT&T, rooted but stock rom)?

You say you're using the stock cable, are you using the stock charger also? It's 2 amps which is higher then most other chargers.
Yes, the charger and cable are both the original ones that came with the phone.

I don't know why it's taking longer, but you could buy one of those USB current meters on ebay for about $4 shipped from China, and actually measure the charge rate of your USB cable. You'll be surprised how some cables are inferior than the other even though they work fine for data.
Also, I don't think the included USB 3.0 cable provides faster charge time. I just use USB 2.0 cable and wireless Qi charging at home. If I use a good USB 2.0 cable, I get up to 1.5A charge rate. When I use a Samsung genuine but thin USB 2.0 cable, charge rate goes up to 1A. Since our battery is 3000mAh, it'll take little more than 3 hours with the thin cable. I usually charge whenever and as often so I don't know how long it really takes.
I think it may be a hardware issue, as I noticed last night that after 3 hours, my phone was actually losing juice while plugged in to the charger. I also noticed that while lying in the table, the screen was going on & off on its own. When I played around with the cable where it plugs into the phone, it would vibrate intermittently. So I'm now guessing it's a problem with the port on the phone.

Try a different cable first. It is cheaper. My son's note 2 was doing exactly the same thing. Cable looked fine but swapping to a new cable solved the problem.

Hey, I had the same problem. I installed wake lock detector and found that carrieriq was slowly eating up my battery. I also installed cpuspy and found that all my cores were running at full speed. After all the trouble shooting I did, I eventually wiped my phone then installed my apps one by one... I figured out that setcpu or any program like that would get stuck on preformance, even if you set it to on demand, it won't stick. Thus leaving your CPU running at full speed...

Battery drain isn't the problem though, it's the phone not charging. A good example is 2 nights ago. The phone was at 76% when I plugged it in and went to bed. It vibrated, the charging icon came on, and the led was red¦ everything showing the phone was charging. But when I got up the next morning, the battery had actually lost 8% juice.
What I found I have to do is put a rubber band around the phone and charging cable so that it's pulling the cable up harder into the charging port. So that means that it's either a cable issue, or the port.
