[Q] Charging issue connected to car stereo USB - One (M7) Q&A, Help & Troubleshooting

Hey all.
I plugged my phone into my friends car stereo usb yesterday to charge it, and it kept connecting/disconnecting rapidly, going from charging to charging about twice in a second repeatedly. The only way I could get it to charge is if I shut the phone off.
Any ideas of why this would be?

Insufficient current output from the stereo's USB socket would be the obvious guess.

Is this going to be an issue with all car stereos made before the HTC One though?
It wasn't JUST the charging that would start and stop rapidly. The USB Connection and Debug Mode would connect and disconnect at the same time, like the connection was actually being turned on and off.

I have this same problem with my girlfriends HTC One. When I plug it to charge from the car's dedicated USB port for charging it just connects/disconnects over and over.
Never had this problem with the Note 2 or my Nexus 4 and 5. They charged no problem.

Diamond does not charge

Hi!
I have a strange problem: sometimes when I connect the charger (mains outlet) to the Diamond it does not charge. Sometimes it it also does not indicate that the power is plugged in, other times it indicates charging but the battery level does not increase.
If I go to battery settings, tick then untick the checkbox "Do not charge when USB is..." it suddenly starts to charge but sooner or later the charging stops again.
Soft reset usually helps. Is there any patch for this?
EDIT: I noticed it mostly happens when I use the Diamond as a Bluetooth modem. If I stop the connection it starts to charge. Maybe bluetooth consumes so much power that it cannot get enough from the power adapter?
Honestly, I found I had this exact issue. I was not using any applications though, it was simply a bad charger.
Have you tried to duplicate this with just using a USB cable to PC?
I found out it is due to overheating. I was using the Diamond in my car, plugged into the car charger. However, the device turned itself off and would not charge. It was a hot morning. I put a hat over the phone to prevent the sun from shihing at the phone and directed the air cooler of the car to the phone. After a few minutes it started to charge.
The brand new charger I got with my Diamond was defective, i tried an older usb charger from my TyTN II and its been fine since.

[Q] Battery discharging when on powered USB

Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

That is apparently a "feature" of WP7-- the phone will automatically turn on when plugged in.

[Q] Phone Powering off When Plugging into Car Charger

I have a strange thing happening with my Moto X. Sometimes (not ALL the time, but more often than not) when I plug my Moto X into my car charger, the phone shuts off (not reboots, but powers down). I have to then power it back up of course, but from that point on it's fine plugged in for the rest of the time in the car. Doesn't happen again until the next time I get in the car and plug it in for power.
Is there any log file somewhere that I can look at to see what's prompting it to power off? Initially I thought it was the car charger/cable itself, so I bought a new one on New Years but even with the new one it is still happening. So it's either the actual car port itself, or a problem with the phone?
I did have a Nexus 5 before this Moto X and it never powered off on me so I'm not convinced it's the phone. I did notice occasionally the Nexus 5 would stop charging though. I'd have to unplug it and plug it back in but the N5 never powered down on me.
And also, when I plug into USB to charge via wall wart charging or PC charging, the phone never powers down. It's strictly in the car.
Thanks for any help!
Did you only replace the cable or the entire charger? If only cable possibly bad car charger?

Tasker In-Car power issue

I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.

Car charger problem

So i am having this problem, wonder if anyone else is also. I reported it to samsung.
The problem is when using a car charge my phone will say charging like normal. BUT then it will says "powering connected usb device".
It will say this the whole time it is charging.
Its a 5v 2amp charger i am using a micro usb cable with the included usb c adapter.
I use the this same charger for my s7 edge without problems.
Now the kicker here. Once i unplug the note 7 from the charger it will keep to saying "powering connected usb device"
The battery icon will flip between the power out icon and normal battery.
The first time it did i had to reboot the phone so it would stop.
The next time it went away after a few minutes.
I havent try using a usb c cable, but will later today.
Just wondering if anyone else is having this problem. Its probably OS related or have something to do with the adapters.
Just wondering if anyone else has this problem
The included micro-usb-to-usbc adapter seems to inhibit the charging speed. I used the adapter with an official Samsung Micro USB cable that came with my Note 5 and plugged it into a Samsung fast charger and the charging takes forever... Maybe you're experiencing a similar symptom?

Its possible. Today i drove for about 20mins and i didnt have this problem. It charged but only went up 3% more. I should of gotten at lest 5-6% with that charger (amount i would of gotten with my s7 edge, same charger in cable)
I will do a test today with the usb c cbale plug right into the usb adapter. I only have the one for the time being
Well the problem is still here.
My wife gotnher phone and the same thing.
She needed to charger her phone.
Plug it up and it says chaning connected usb device. Just stays on the screen for a while then goes away.
Now we got out the car and turn the car off.
Then phone lit up and says powering conntect usb device. Then my rasio started to boot up and ended up in a boot loop as long as the phone was connected.
So thephone was trying to power my car through the usb charger.
This is something samsung should fix asap. There should be an option to turn this off.
Ill have another chat with samsung
