[Q] GPS, batteries and car chargers

Hey guys
Have got the GPS working properly on my SGS (props to those who figured that out) but I've noticed something a little concerning.
When I'm running google navigation that battery continues to run down, even when its plugged into my car charger. It'll survive for a good few hours, but it seems a bit bad to arrive at wherever I'm going and need to borrow a mains charger when I get there.
Anyways, I'm normally running bluetooth to my jabra speakerphone/fm transmitter, but nothing else that should agitate the battery too much, and with GPS turned off, it happily charges even with the screen perma-lit.
Im running stock JG5, and my dash charger consists of a cigarette lighter to USB converter and the stock USB cable.
Any thoughts on whats up with this would be greatly appreciated!

The phone is probably consuming more power then the 500 mah charger can provide. You need a dedicated mini usb for charging, the ones that actually are usb cables only provide half power

[Q] USB Charging?

Just got a Tab but I bought it off of someone who couldn't find there charger so I had to find one locally quick and the ONLY store that had it in my area was Verizon but it wasnt a Samsung branded OEM charger, It was a Verizon charger that was suppose to be the same but It doesnt charge via USB and Im wondering if for some reason its not suppose too? It charges USB when the Tab is off but when its on it doesn't? I can only charge it via wall charger when its on? So, is That normal? Or, does the OEM USB charge it while its on and this Verizon one is just messed up? Thanks.

Yeah. I got the Samsung Charger. Charging through USB from a computer is super slow to useless.
Only plugging to a wall provides sufficiently speedy charging.

The Tab is quite greedy for power and using either the USB port on a PC or a low Amp rated Mains USB charger will result in either the phone charging very slowly or not responding whilst under charge.
Charging the Tab using the USB and a PC, well there's nothing you can do about it as the USB standard only distributes 0.5 amps (500 milliamps) of power through each port.
Mains chargers however are rated higher but most common one's only have a Max of 1.0 amp.
What you need is a charger that has the capacity to deliver 2 amps.
Check Google & Ebay, there are a number of chargers available rated at 2 amp.

So usb charging while the tab is on is impossible, right? The charger charges fine plugged into the wall, I just needed to know if it not charging via usb while the tab is on was normal, and from what I get from what your saying is that it is normal, it will not charge usb while the tab is on... thanks.

No, I didn't say it was impossible. I said charging via the USB port on a PC will either be very slow or may not respond whilst under charge, it's certainly not the best method. It's just that with only 500 milliamps of power trickling through the USB port, the second you start to use the Tab in anything that requires a decent amount of power you are not going to get any charge.
The only way I find an ability to charge the Tab under a USB connection when connected to a PC is to let the screen on the Tab turn off and not to touch it. It will still happily communicate with your PC and send/receive data but it will take a much, much longer time to charge that's all.

I gotcha, so...when my tab is on it says not charging in the status but if I let it sleep it actually will just very slow... I understand what your saying and thank u for your time, I just wanted to make sure it wasn't the usb cable I got to know to take it back or not...

I charge mine at night via USB to my computer. Starts around 20% by the time I plug it in. I don't power off the tab. Always has a full charge in the am.

I have a double usb cable that is used to power an external drive. I would need a female to female adapter, but this should provide more power to the GT.

Yes, providing the cable you have charges when using with a mains plug then yes, the cable is good.
If however the cable did not charge even when using it with a mains plug then definately you would have a sync only cable.

Thanks, I'm just gonna let it sit overnight with it on sleep n see what happens

To charge through your PC with official USB cable, you should make your own USB "bridge"as short the data wire while insert an 33K om resister between gcc and data wire, an 10K om resister between gnd and data wire.

Yep... I left it on the usb in sleep and it did charge so the cables fine, It just sucks that it doesnt when the tab screen is on but oh well... If theres any solution to fixing this that it charges well from usb then let me know, I know someone just commented about modding the cable to work but theres gotta be a better solution...

Sounds like u bought a stolen tab. No charger or box?

just used a spare double-headed cable from a portable hdd that fortunately has a full size usb plug on the other end. (Most have mini-usb at the drive end)
I use it with a female-female usb adapter and it works pretty well for the PC, particularly on USB 3.0 ports.
I also saw these on Amazon:
amazon dot com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE
I believe Blackberry do one for the Storm as a standard accessory as well
For the car I got a car charger designed for iPad with a USB socket that delivers up to 2.1A
Belkin has the car charger

(I should say, I don't actually have this one, mine is a generic brand that also has a 1A usb socket)

cheap chargers....

no need for all that, just plug it in computer USB and wait it take sometime but it charge, because pc USB are not powerful enough to feed 2A to the tab.

[Q] usb data cable - charging problem

when the usb cable connect to my laptop is charging my xt860 without any problem.
but in my car it's not (with the iphone it's charging perfectly)
any idea?

Whatever car charger your using is not supplying enough power to charge the phone. A lot lf laptops will have a continuous 5v (just enough to chage the phone). But the car charger prob only puts out 4v and the iphone is alright with that (charge really slow) but the phone is picky (won't charge at all). All I can say is try another car charger.

I grabbed a Motorola brand one off Amazon for $5 and have never had an issue. But any brand name microusb car charger should work as long as it puts out enough current.

[Q] Car charging at half speed?

Does anyone know why the One might behave differently on a car USB charger compared to a Galaxy S3?
I noticed my One was charging slowly or not at all when in the car. Using the power stat screen in the SystemPanelLite free version it shows the One is only connected at USB charge power, not "AC" power. However if I plug this same cable into my old Galaxy S3 it shows in SystemPanelLite that it is charging at full AC speed. I tried both the One and S3 default charging cables, no difference.
I'm using a car charger rated to put out enough amps for full speed charging, and it works great with the S3. With my One I tested it just plugging it into the charger that came with it (AC outlet, not in the car) and only then do I get full AC charging speed.
Anyone have ideas on how to get full AC charging speed on the One in the car? Any suggested car chargers confirmed to charge at full speed?

quick charge is disabled. you also need to make sure the charger is at least 1A @ 5V.

On previous HTC phones, I'm led to believe that the data pins on the USB connection are shorted inside the charger, and that's how it detects AC vs USB. It's not AC arriving at the phone of course, in reality it's 5VDC, with "AC" it draws 1A vs 0.5A for USB.

If the USB cable is not wired appropriately, the HTC One will slow charge so that it doesn't draw more than the USB standard 500 mA. Your charger needs to be wired accordingly so that the HTC One knows that the charger is capable of supplying more current, otherwise the device won't pull the extra current to fast charge. See http://forum.xda-developers.com/showthread.php?t=844284 for details.

Benpope and rumball have correctly answered.

Will this charger work with the HTC One @ 1A? http://shopamerica.htc.com/product/productpop.htm?prId=41645

Well at this point I'm looking for anyone who can confirm they have a car charger/cable combo working with the One that will charge at or near 1 amp.
I don't think my cable is at fault since I've tried multiple ones, including the AC one that came with the One.
Although my current car charger worked great with my GS3, I guess the One is more picky. So can anyone recommend one that will definitely do 1 amp with the One?

the data function on the car kit cable doesnt work as well...plugged into computer and charges but nothing else (to bad to, liked the length of the cord)

This is right, I had same issues with s3, resolved by buying a genuine Samsung charger. Before my Google maps drained more than it could charge. What's odd is that the s3 charges fine on his cable, unless different pins are shorted on an htc?

Have you used it and confirmed it charges the One at "AC" speeds?

[Q] Battery drain while connected to car charger

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.
Sent from my One using xda premium

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.
