Hi,
Today I was using GPS app - HTC Locations. In about 45 minutes battery went down from 100% to 50% (I noticed that using satellite GPS makes the phone very hot) and I decided to connect a charger that I have bought recently - HTC CC-C200 car charger.
The problem was... the battery was still being discharged!
I turned off the nav app and left only basic system apps and the phone was charging only about 5 percent in 30 minutes. Keeping in mind how fast the phone was discharging using navigation, it is simple that the car charger won't do.
Anybody else has this problem? How can I actually use a navigation??
is it the official car charger from t-mobile.

It is original HTC's car charger - CC-C200
One question - can an USB extension cord (plug in to this original HTC's charger and then original HTC USB cable to this cord) decrease the speed of charging?
Car chargers will always charge slower. 12v vs. 110v.

Are u sure that the 110V network adapter, charge the phone with 110 volts ?
The 110V charger:
HTC New Slim Design AC Adapter TC E250 (with EU Plug Unit + micro USB Cable, 5V/1A
and the car charger:
HTC Generic Car Charger with USB/micUSB Cable CC C200 (1A/5V)
have SAME charge power: 1A at 5Vm that is 5W.
The PC USB ports are rated at 500mA, but if u check the port with digital multimeter (cut the cable and put Ampere-meter) u can see that u can drain ~700-800mA , Asus and SuperMicro Motherboard tested from me
@EniHS if u make the lenght of the cable bigger the electrical resistance grow too . I think that 1 meter more wont be such a problem, but if u really wanna check how this will change the power of charge u need to measure it with Ampere-meter
This is an easy one... I try to never get the charger from the store because it (usually) won't put out enough juice to keep up.
I found that if use the same current for charging my ipad, it works much better and can keep up. With that in mind, you can purchase any charger with a 2 Amp output (10 watts) that has a generic USB connector. Try the search "10 watt usb car charger" on Google or Amazon.
Get the free app "juice plotter," which will plot your battery usage and charge. If you're plugged in and the plot is still going down, then the drain is still greater than the charge, and you'll need a better charger. Good luck!

That would be a solution. I'll buy 2A 5V charger. I assume that I should only replace the plug and the USB cable can be left from original HTC car charger?
Isn't it dangerous for the phone to charge by 2A instead of 1A (original charger)? Or the only difference is the charging speed?
Solved!
I did some tests today and discovered that if I charge the phone normally (no program running, GPS off) with HTC car charger WITH extension USB cable... phone was charging 1% in 25 minutes!!! That would be over 40 hours to charge the device from zero to full! I thought I had charger broken, but... I tried with NO EXTENSION CABLE, just the HTC plug and HTC cable, then the phone was charging normally 1% in 2 minutes!
So... the problem are extension cables, but still don't know why...
I noticed this even with wall chargers. Yesterday when I bought my phone, I plugged it in to my old charger & noticed it was charging slow. Once I switched to the charger that came with my Sensation, it charges normally now. I haven't looked at the chargers to compare if something is different but it is very strange
Isn't strange at all, it's essentially that they are not being supplied a great enough charge and so power from the battery is utilised in addition. ideally you want above 700mAh for standard charging/use.
On the Samsung Galaxy Note 2 (basically all Samsung Galaxy device), their two data pins on the official charger are shorted to be verified as a official charger and enable fast charge. If I connect it to a no-branded usb 12v charger, it takes a very very very long time to finish charging (like 5 or more hours bevause it only want to recieve 350mA rather than the higher rate on the official charger). I remember I dont have any problem charging my HTC Desire HD with the Samsung charger. But if I use HTC charger on Note 2 it also needs hours and hours to charge.
My question is what brand/model uses the 2 data pins to verify (or know how to charge when they are shorted) so that damage will not occur. Anyone knows the answer?
Several things going on here. There is a difference between USB and AC charging mode. I have had to short two wires in my car adapter to get my Nexus 7 to start charging with AC mode. Don't assume that every charger is capable of charging at the same rate. If you have a 350 mA charger, it won't charge your device as fast as a 2A charger.

I didnt mean that every charger can charge at the same rate. I wanna modify a 2A charger but I'm scared that if I unexpectedly connect it to an incompatible phone and something bad will happen. If a no-branded charger (data pins are not shorted) is connected even it's on the wall plug, the device will set it as USB charging and lower the receiving voltage so the device will charge very slow or the battery percentage will be dropping even when charging while using. My HTC charger can charge the phone that it belongs (Desire HD) in 2+ hours but the Note 2 needs 5 hours (this means that the HTC charger has no shorted data pins). And the Desire HD wont get an error when using a charger with shorted data pins (Samsung charger). What I want to know is what phone cannot be used with a charger with shorted data pins in case someone (or myself) use my modified charger to charge a incompatible phone and let damage occur.
Has anyone managed to get a car charger for this phone?
I've just tried to charge the phone with my car charger modded to "AC" mode by shorting the middle pins... and the S4 gets nada...
Have they changed the charging mechanics?
Is that what's going on? I was wondering what the heck was wrong with my charger!
Yup, the car charger still charges my old HTC, even with the Samsung cable... so there's definitely something different inside the charger...
I have a 2A usb car charger with generic cable to charge my devices. It's nothing special, but it works with my S4. Hope that helps.

I have a 500mA car charger and it didn't work. Even though it worked on my Xperia Z. I bought a 2A charger from Maplin and it works just fine.

Hmmm will have to look into getting a decent 2A charger then and NOT modifying it...
So I opened up my car charger and un-modded it back to original and it works like a charm now
I've got a 1A Belkin car charger and it seems to overload after a while when charging my gs4.
The green light on it blinks and my phone makes that sound when you plug in the charger.
Takes a while for it to happen but gets more frequent the longer you have it plugged in.
The charger works fine with my gf's nexus 4.

I'm using the Motorola charger (big blue circle). Got it for my Razr Maxx a year or so ago (I've gone through like 4 phones since then) and it works wonderfully. It's the best micro-USB car charger I've ever seen. Coiled cord, huge blue light (but not too bright since it's an ambient-style light), and charges quickly.
http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA
Seriously, the best car charger I've ever owned. 950mA is also one of the highest car chargers I've used.
I used to have that same motorola charger but I just switched to this one by SPIGEN: http://www.amazon.com/gp/product/B0069EGLFY/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
It charges at the same amperage as the stock wall charger that came with the S4. I use the Galaxy Charging Current app to check.

Do you use it with the original cable or a generic one? I read that there are some differences in charging amount using also different cables. This SPIGEN Car charger looks very interesting. Thanks!

I have tired a few most only charged at 400-500 m-amps (aka running with gps and screen on discharged it faster then it was charging) with some random picks at fry's i found one that was marked 3 amp charger that whould do 780 m-amps so the phone still makes head way chargeing while being used as GPS
FYI the tool i use to measure says the Samsung charger is 1900 M-amps and my apple ipad charging brink is 1400 just for reference.
tool is Galaxy Charging Current Lite i would link it but the forum will not let me

You can also use elixir 2, the battery stats will give amps while discharging and change when charging. I think it uses the current_now as reference.
I have a 2a usb car charger and I just use the usb cable from the phone. I bought the car charger from best buy.

Different USB cables do pass different current even if using the same charging main. From tests I've done so far, a generic 3 ft USB 2.0 cable I randomly purchased online only allowed around 400 mA. An old Blackberry Torch 9810 cable allowed around 1200 mA. Original cable that came with the S4 allows 1900 mA. These numbers are from using the original wall charger main that came with phone.

2A Chargers with the Nexus 5?
My Nexus 5 1.2A wall adapter died overnight. Will not charge anything I plug into it, though the Nexus 5 microUSB cable works with other USB adapters I own.
Google wants me to ship back everything, including my defect-free Nexus 5, to replace the wall adapter. Not going to do that....
My question is: would it be ok to charge my Nexus 5 with a 2A charger? I have some 1A and 2A chargers around the house, but do not have any 1.2A chargers like the Nexus 5 one. If not I'm looking to buy something like this: http://www.amazon.com/PowerGen-2-4-...=1383756651&sr=1-4&keywords=1.2a+wall+adapter

Yes. That is fine. The phone will only pull what it needs. I use chargers from 0.5A all the way to 2.1A on all my devices.
Thanks for replying. Using chargers I already have will save me some money then.

Escalate the ticket with them and ask for a supervisor. There's no reason they need that phone.
I think I will. I didn't have the time or energy to argue with customer service this morning.

I plugged the charger into a surge-strip and plugged my phone in before I went to bed (battery charging indicator appeared). Woke up and the battery was low and no charging indicator present. I tried another charger and the phone charging indicator appeared. Nothing else plugged into the surge protector was running either, and we didn't have any storms or weird weather last night in AZ.
I tried plugging something else into the Nexus 5 charger... nothing. Tried the Nexus 5 microUSB cable on a different wall adapter and it charged.
So yeah, the wall adapter for my N5 failed. Luckily in the hour before work my 2A charger got the N5 up to 70%. Topped it off to 100% on my wireless charger at work.

What brand was your 2A charger?
Beware: The nexus 5 will charge in USB mode for the 2 amps chargers (and a lot of other ones too). To solve this and charge in AC mode, you will need to buy a "charge-only" USB cable from amazon.
i charge my n5 with my 2012 n7 2 amp charger and all is good it also charges at the expected rate not a slow rate, ive used it every day since i have had the n5 which was the release day

This is interesting. Three questions.
What exactly does it imply in what mode the phone is charging?
How do I know in what mode the phone is charging?
Can I check cables for its purposes without destroying it?

1. AC Mode charges at a much faster rate than USB mode.
2. To check which mode the phone is charging in go to your battery settings and it will display on the top left
3. There is nothing to check with the cables, if you don't know if you have a charge only cable then you don't have one

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger
