[Q] Charge from PC in debug mode?

I have My Tab plugged in to my PC all day while debugging on it as I develop, unfortunately the fact that the tab somehow and for some reason disables charging while debugging is causing a huge problem for my workflow.
Can anybody suggest a possible solution that will allow me to charge and debug at the same time. My boss may consider allowing me to root the device (I know it's easy, I could do it right now, but it's political) if I know it's the only option.

The power outlet of the USB port isn't enough to charge it, which is driving me nuts too.
If you root it you can use ADB wireless (free app on market) to use adb over the wifi, and have the tab plugged into the wall. Otherwise I don't know. Maybe a hub with it's own power supply **might** do it, but I'm not sure.

Thanks, I assumed it was a software check that it's connected in debug and simply disabled.
My boss has agreed to allow me to root it on the basis that I can restore it to factory if required.

Cool beans. Glad I could be of assistance.

I'm still surprised it's that much of a beast that it needs more power than the USB port can supply, I mean, is it all because of the screen?
The wall charger does 2A
But the specs aren't any higher than my HTC Desire except for the screen and that only needs 1A from the charger and can charge by USB too.

I genuinely have no idea. I'm given to understand that the Tab does charge from USB, albeit slowly. As for why it needs 2A, who knows. Maybe Samsung don't like us using other chargers.

Well my Tab doesn't charge from USB unless it's switched off. If it's on, the Battery symbol has a line throgh it, as in "charging disabled".

Yeah, mine does that too. I just use wireless ADB now, so much easier

I think you will find that even in those circumstances it is still actually charging, albeit very slowly.
I had my Tab hooked up to my PC last week and when I connected it up it was showing that it wasn't fully charged, and didn't appear to be charging. However, when I disconnected it some time later it appeared to be fully charged.
Perhaps it would be worthwhile downloading JuicePlotter to see what affect, it any, connecting the Tab to your USB port has.

It's not the specs of the device, it's the size and resistance of the battery. It charges slowly over USB, and it charges a much smaller percentage of the battery's capacity than it would with a smartphone.
Easy math, it's over 3x the capacity of your Desire battery, and as you well know, even your Desire battery charges slowly over USB compared to mains.
The larger backlight should consume about twice the voltage of a 3.7" display (rough estimate), so you're barely pushing any charge at all via USB when the display is on, a trickle of a trickle.

You're right, I probably should have looked into the rating of the Battery in this thing. As an Engineer, the math is trivial.
Still, It appears to me that it's not charging at all, not even trickle, from full charge when I left for work this morning to empty before the end of an 8 hour working day with it plugged in to usb the entire time, slightly disappointing result.

Just as a matter of interest, I installed JuicePlotter and attached my Tab to my laptop and adb'd into the Tab and left it for a while. JuicePlotter definitely shows the battery charge rising, but probably only in the region of 5-10% per hour.

This power thing is annoying. I bought a 1 amp car charger USB adapter when I got my HTC Desire as running my satnav software on it otherwise depleted the battery quickly. The 1 amp charger was enough to charge the phone while running the software.
However, if I use it with my Tab, rhe battery is still running down while using the satnav software, although slowly.
If I got a 2 amp car charger adapter, would that solve the problem? Can one buy 2 amp adapters for the car? I don't reallly want to buy the way overpriced Samsung car charger, which isn't even available yet.
EDIT: OK I've found 2 amp USB car chargers are available. Will 2 amp be enough to charge the Tab while running the satnav software?

I have never seen a 2A car charger but yes, that would do the trick if you found one. I assume Samsung's will be 2A, how much is it to be "overpriced"? A 2A Samsung official car charger is probably worth about £25 I'd say.

[Q] USB charging current???

I think there is a serious problem with my charging circuit on this phone. I have no idea if its hardware or software that is controlling the charging circuit but I can tell you that it literally takes forever to charge my phone via USB and this is unacceptable from a consumer standpoint.
I wanted to see how much current the phone was asking for and I was really surprised to see 96mA!!!
No wonder its charging so slow, something is really wrong here, and It doesnt look like a faulty battery. The phone should be asking for 10x this much current.
Can some people post how much current their phones are drawing from the usb port?
If you dont know how to do this, in "device manager" double click on the appropriate "usb root hub" that your phone is connected to and click on the "power" tab. Post results.

You are trying to charge your device on a pc correct?

500mah is the max just about any phone will charge at from a usb port, at least without any modifications like fast charge drivers.

USB current, for charging purposes, is and always will be low. Otherwise you would burn up your motherboard. Alternatively it would let the magic smoke out of your phone and it would quit working properly.

+1 to the two posts above me. I suggest getting a wall adapter for your usb and charging it there, you will get vastly superior charging times

USB current, for charging purposes, should be and always be 500mA. 96mA is not enough to charge one of these phones. You cannot burn up your mother board if the device calls for more than 500mA, as that is all that is available for each usb port.
Ive connected three of my old phones and an EVO and a mytouch Slide, they all ask for the maximum allowed current as they should. I do have a wall charger and it charges fine, Im trying to see if everyone else has the same USB charging problem as me, or if I have a broken phone, or if I just have some bad software on my phone.
Please if anyone can post results it will be helpful.

thanks but can you please post results for the an EPIC 4G phone?

Connected to a PC USB port, the Epic 4G will only draw 380ma. Via a wall charger is will only draw 600ma. Hence why charging on a PC is slower. Simple as that.

I also show exactly 96 mA, regardless of which USB port I am plugged into. Practically new motherboard, so I know the USB current isn't an issue. New Blackberry USB cable (far superior to stock Samsung cables).

IIRC, 500ma is the max draw per hub, not USB port. This is why people get powered add on hubs so they can have components that take more draw than a computer USB port will give.

500Ma is NOT the per 'hub' power supplied, 500Ma is the PER PORT current max. EACH port on the motherboard will supply up to 500Ma, trying to draw more will not work. It won't burn it out, it just won't supply any more than that. If you have 8 ports on your MOBO, you will get a total of 4A of current in total, not exceeding 500Ma per port. If you hookup an UNPOWERED hub to your mobo, the total draw still cannot exceed the 500Ma. If the hub is powered, it will provide 500Ma to each port on it, and draw virtually none from the MOBO.
This is why you see some external devices with dual USB cords, or a single with a Y. This is because it will combine the 500Ma from each port to power the device for up to 1A of current.
96Ma will not charge the phone, it's not even enough to power the phone while making a call.
How are you measuring your current draw? Try other USB devices. Wall charging takes between 2 and 3hrs to charge depending if the phone is on and its current draw for what it's doing.

Pretty much every USB host device I've used can easily deliver 1A. Most new machines can deliver 2A (such as ASUS boards and Macs) over USB. The Epic still charges way too slowly even off a wall charger. It'd be nice if it drew 1A instead of ~600mA. Most other devices use much higher charge currents when plugged into AC.
As for the Epic's charge current, I think the USB driver on it just reports charge current incorrectly.

thanks to the two people, that haven't been derailing this thread into a "how usb ports work discussion".
if anyone wants to help instead of arguing over how usb ports work, it would be really helpful to know what rom and kernel you are using when you tested your epic 4g device.
Im especially interested to know this information about orbiting who is getting 380mA. Im also interested in how you measured measured the 600mA from the wall charger.
Its posted at the end of the OP how to see how much current your phone is asking for.

I think the charge controler on the Epic will alter the current draw depending on how close it is to fully charged . Once it gets above about 90% charge the current should taper off. this is to prolong the battery life.
The Normal charging times starting at about 30% is under 3 hours on a wall charger for me. I can go from about 70% to 100% om my laptop in about an hour.

I appologize for wasting your time, but let me elaborate.
Right now my phone is at 89% charge, and right now the "Power Required" field in the USB root properties is showing 96 ma. I doubt that is an actual measured current, more likely it's what the port controller on the Epic reports as a minimum current required. What I can tell you is that even with that info, my phone charges fine. Seems unlikely that it's only supplying 96ma because I'd expect the phone must draw 40 ma or so just to idle.
What would be more useful would be an app on the phone that polled the charge controller to give us actual voltage and current data. I had one on my old TP2 that was great, but I don't know about one for Android.
Edit: in the time it took to type this reply the State of Charge went from 89 to 92%, yet the properties still shows 96 ma. I think the controller is getting way more than 96ma, so that number is likely bogus.
I guess that wasn't what you asked for either, but maybe it is stilll useful

no need to apologize, I could explain to you why what you think is "more likely" is actually less likely. but it would only further derail this thread. feel free to pm me if you are interested.
all im interested in is three things:
current asked for by phone from pc usb, rom version, and kernel version.
someone already reported 380mA. but i have no idea what software he is on.

I'm running completely stock EB13. On my newer laptop with Windows 7 it shows 96mA in the device manager. On my ancient Dell PC at work running XP, it shows 96mA as well. In both cases I'm plugging the phone directly into a USB port, no external hubs.

Nexus 4 - Xbox 360 charging problem

Hi guys,
currently having a problem with my xbox 360 charging my Nexus 4...
basically i put my nexus on charge (usb cable from xbox 360) over night and it clearly said its charging, so i woke up the next morning and the battery % was as i left it, but it still clearly says charging? this has happen to me twice this week... has anyone else had a problem like this?

forgot to mention, i have always charged my mobile devices using the xbox 360 and never had any problems before...

Maybe try other cables?
I have had similar issues with phones in the past where certain cables worked and some didn't.

accidently gave u a thx I had this problem with all my phones trying to charge them with my PS3 or PC. With my PS it charged 1-2% and with my PC a bit slower than normally. I think its the bad electricity supply over usb

I had similar issues while charging through my laptop, My phone would say charging, meanwhile it would be discharging
I think it has to do with the phone using more power than the port is giving out. Basically some apps you have one your phone is using so much battery that the charger is not charging because the required power to run the phone is greater than the charge is giving. I'm thinking this is becasue the phone has so much RAM that all the background apps are using more and more power. It's like charging a Laptop through your Xbox USB port, the laptop uses WAY too much power for it to be getting charged through a measly USB port.
Nonetheless, I stopped charging my phone through my laptop and just plugged it in the wall. It charges way faster anyway (my charging usually takes 2 hours when it's really low to full battery)

Even if it does charge, it's not likely to charge well; the Nexus 4's charger is 1.2 amps. The Xbox USB ports likely put out less than half that. Unless you have an S model, in which case the rear "Kinect" port is "high-powered," which likely means 1.0 amps.

I'm charging off my AirPort Extreme without issue...albeit it slow. Since I charge at night, it's a non-issue. OP, have you tried swapping USB cable?

Does the Xbox 360 temporarily disable its USB port if you try to pull to much power from them?
The Nexus 4 requires more than what is supplied...

uberSlackr could be right, normal usb ports are 5volts,500mah, so 5 volts standby, you should be able to charge even at a slow rate, windows 7 has an option to turn off usb ports to save power unless you disable it.maybe xbox has a similar power saving function.
samsung s2 max charging rate is at 650mah, my nexus charger is 1.2amps, so 1 amp draws too much.

yes, i've tried changing the cable and its the same... i believe the comments above have explained it much clearly to me and make me understand why its not charging (xbox usb being 500 mah and the phone needs 1.2 amp... so looks like i will have to use my wall charger from now on)
i appreciate the help guys!! :good:

USB fast charge, how to enable?

Im not sure if anyone would be familiar with this, but on my samsung galaxy nexus there was an option that was universal on all kernels called "USB fast charge"
which basically all it did was cancel out the support of file transfer while connected through USB, but in return gave much higher charging speeds through USB. With it enabled my galaxy nexus would charge almost 4x faster.
Is there an option for this on the note 3? I have not rooted yet, but will in the next few days. I understand its up to the kernel dev's and whatnot to implement it in, but is this feature available on the note 3?

Hmmmmm, odd. Does your machine have USB3 ports? I know that's supposed to be good for only speedy file transfers, but I wonder if it also speeds up Charging? I've just never noticed slow trickle charging from my computer. The only time it's slow is when I use a regular USB2 cable in the car....then it's slower than molasses in January.

I do have USB3 available on my computer, but havnt tried it for charging yet. So far my USB charging has been done through my car which is some random usb 2 cable. Which now that i think about it i believe its only a 1 amp charger in my car, if that. It was enough for my galaxy nexus but probably not so for the note 3. The note 3 wall charger is i believe 2.0 amps?
Im wondering if charge rates matter through usb2 / 3.
If i get a 2.0 amp car charger and use it with a usb 2 cable, will i still achieve 2 amp charging speed? Or for the note 3, i have to use a usb 3 cable?

Not sure. My Laptop has a USB port that charges devices even when the Laptop is turned off, but I do know that my Nexus required less juice to charge up, where the N3 doesn't keep up when I charge it in the car, so I think it's the 1 / 2amp question

How long should it take to charge?

It means that charging faster will reduce the overall life of your battery because the battery and phone doesn't support it. The Galaxy S5 supports USB 3.0 and Qualcomm Fast Charge.
Also, the fast charge on your Ace 2 just means that it will draw maximum power from USB ports. It doesn't change charge speed with a wall adapter.

a ok,so the ace 2 gave you the ability to charge it faster than the normal with the disadvantage is that it reduce the battery life..
then my mistake sorry

True? Over not true? Ffs
Sent from my SM-G900F using xda app-developers app

My gfs s5 is charging so slow. About 2 hours charge it goes up by only 20/30%. I am guessing this isn't normal? That is using the wall charger and not sub.

seems a bit slow.. you are using the adapter it comes with? are you doing anything intensive with it while it charges? ex skype or something?

Use the original cable and adapter. If you think that's too slow to charge, like taking up to 5 hours, that's unusual. Let your carrier or the store check it for you.

Yeah, using the cable and adapter it came with. Nothing is getting used when it is charging. It must have taken about 6hrs to charge during the night.

does it take long if it is charging while off as well?

This is just wrong. I think my charge is almost 1% per minute - pretty quick.

Hi. I have a G900F and I have noticed that my new S5 charges much slower than my old S3.
If I check it with "Galaxy Charging Current" or GSam Battery Monitor" it says that only 450mA is used even though I have connected the phone to my Laptop using a USB3.0 cable on a USB3.0 port.....
Any advice please. Thank you!
