Has anyone noticed that phone does not charge while using GPS. The charging indicator is on but when I look at the stats it says discharging at -450 mAh. Is this the way it is and if so, is there a fix? 1 hr 42 m with 73% display on battery use and 43% charge remaining, but was plugged in the entire time while driving under an hour home. I am using the same Motorola high performance charger that every other phone is charged fully even when using GPS.
are you absolutely sure the charger is giving the full 1A?
What sensor app are you using to see the battery discharging?
Mine charges normally with gps on.

I was curious so I tested this with "Battery Monitor" I have it plugged into my laptop currently which only gives +500mA. and not the +1A that you get from a wall/car/high power usb port.
the app is showing +257mA with GPS on and functioning normally.
So charging good here... Might be something with your motorola charger? It could have a sensor in it to detect 'trickle charging mode' that is improperly engaging when connected to the HTC causing the charger to put out a minimal 'sustain only' level of amperage.
good luck!
you need a charger putting out 1A ... most car chargers put out 500mA so find a good one off monoprice
Here's what I'm doing. I have a Belkin 2.1A(2100mAh) USB car charger dongle. The problem is, once i connect the USB cable to it the phone registers it as "Charging USB" and does notcharge anywhere near as fast(power-wise) as if the phone was registering it "Charging AC". I'm not keen on using a power inverter to get the full AC charge so instead i am going to go pick up a cheap micro USB cable, splice it open, then disconnect the data wires(green & white ones) & then tape it back up. By disconnecting the data wires, the phone will no longer think it's a USB connection and then charge via AC, getting the best charge possible.
that should work ^ if thats the problem
I've found that using the included USB cable with a Belkin dual port USB car charger allows the phone to charge as if it were plugged in to a wall. I'm guessing the included cable has a different layout than standard Micro USB cables.

I'm guessing that I have the same belkin dual port (2.1amp and 1amp ports) and the best I've seen out of it is about 250mah charging. This is using the supplied usb/micro hdmi whatever cord for the phone.
I have seen discharge rates off the charger of 750mah which is the highest I've seen on any phone. I'm guessing if you are using the nav on your phone with the screen on, it will probably still be using battery while plugged in.

Possible, but says AC charging in Battery Monitor widget. I will post a few pics.
Here are a few Pics. you can see a couple of things.
-Charger rated at 950 MA out. and no other phone I have owned lost a charge while driving including TBolt, Charge, Bionic.
-Shows as AC charging
- Spikes of good charging detected
Put on Normal power mode today on the way in. live wallpapers did not wrok, just flickered. 3G on vice 4G. Battery still went down, but above 90% on 40 minute drive in. Screen low but on. Bluetooth speaker.
Maybe it is the iBolt car mount. See review online. will try without dock this afternoon on my way home.

Pros: Options for different backs
Cons: Does not charge the phone while it is in use
Try playing pandora when the phone is 100 charged. After 45 minutes on the car mount (and yes it is plugged into a charger and all indicatros show it is charging) and the charge level is 84. Using the same charger but plugged into the phone, playing Pandora for 45 min starting charge level 68. Ending charge level is 100.
Yeah, something is telling that charger to not give you full juice

ok, drove home off the window mount and just on charger, all same except full brightness on screen.40 minute drive. came up 7% battery vice down from 100 to 43%. nedd a few trials to confirm, but looks like window mount is throttleing juice.

i have seen spurts up to 913 with GPS off and screen just turned on. Using battery monitor widget. Not on window mount, just charger.
I can confirm. The car dock will not charge your phone atleast not with the screen on and nothing else running but battery monitor widget.
I bought one and tested it extensively yesterday. I used a Verizon 1a charger and a generic 1a charger. With the dock and both chargerz the phone DIScharged(as in LOST battery power) at between 100ma and 200ma. Without the dock using the same chargers and changing nothing on the phone the phone charged at between 50a and 300ma.
I did the test several times to eliminate any random things the phone may have been doing in the background.
After doing that controlled test I played with it some more and no matter what I did I could not get a positive charge with the dock attached even in airplane mode with the screen backlight at minimum. Without the dock using the same chargers i ran Pandora and a police scanner both outputting through the phone speaker, gps, wifi, mobile all on, and screen on auto and still had a very small positive charge.
Moral of the story DO NOT BUY THIS DOCK unless you dont mind it just being a piece of plastic that holds your phone in place.
I wonder if there's a quick mod to it to get it working right. Like the soldering of the USB chargers I've seen.

I just went ahead and bought an extra battery so I wouldn't have to charge in the car. Only takes 20 seconds to pop in a new battery.
Can charge both batts while I sleep at night.

I was looking for a high current charger for my Android tablet and there was a review that talked about compatibility. Some of the high cap chargers appear to be designed for Apple products and the pin wiring is subtly different. So, on some non-Apple products, the charge is only recognized as a lower power, 500mah charger and the users reported that some devices would normally charge and others would not. Some of the dual port charges also split the power. The 2.1 amp port and the 1 amp port cannot be used at the same time, depending on what is plugged into them. This was also brand specific. I ordered the Amazon Basics 2.1 amp dual charger and will see how that works. I have noticed a difference in charge rates between my Motorola charger left over from the Blackberry and the Verizon OEM one. The VZW one is faster.
I do the same thing I have been doing since my Windows phone days.
I use the AC cord plugged into a 12v to AC adaptor(screen set to 100% bright and no timeout).
I drove 6 hours last week ruuning Google Maps/GPS & my battery was 100% charged when I got to my destination.

Are all USB car chargers like this? Can I prevent this by getting a higher quality charger? When I'm not using maps or navigation (or turn off the screen for a while), then it'll slowly charge back up.

GPS is usually a big energy hog. How many amps is your car charger?
You should be able to get away with a higher amperage charger, but the trade off may be reduced battery life.

How fast does it discharge? I just went on an out of state trip last week and had gps on with the charger plugged in for several hours at a time. I didn't pay attention to the actual charge numbers, but it either discharges very gradually or charges very gradually. I could probably run it all day with the charger and gps without a problem. I don't recall the amp output of my car charger, but it is one of the cheap foreign models.

Reflash your ROM, dude. I had that problem on one of my initial GB ROM's where I had bad drain using GPS while charging in my car. I redownloaded and wiped everything and reflashed the ROM and everything was good.

If you are running a custom ROM, you can use SetCPU (or any other CPU clock control app that allows profiles) to set max of 800MHz when plugged in. This should at least get you to even charge/discharge levels when plugged in and running GPS while driving. Probably will depend on your screen brightness.
I don't run GPS long term very often right now, but I was for a while and FWIW, I was able to stream pandora, run google maps with screen on, not have any lag, and get a slow charge from my car charger by limiting clock speed to 800MHz.
Your other option (and what I usually do) is turn off the screen during longer sections of GPS nav with no turns (like sections of highway). You'll still get audible notifications for the next turn/maneuver/interchange/whatever, and you can turn the display on then if you need visual along with audio nav. The phone shouldn't have any problem charging and running GPS with the screen off...

Not all USB car chargers are alike. You need two things:
1. The car charger outputs higher current than 500ma. You need at least 700ma.
2. The charger is wired correctly to be recognized by phone as AC charger instead of PC USB port so that the phone will actually draw more than 500ma for charging. You can go to phone's status page to read what charge mode it is using.
Most iDevice chargers will not meet #2.
I have a stock Samsung car charger and it charges my phone while using Google Nav.
Thanks for the tips guys.
My phone discharges at around 1% every 20 minutes or so. I've been doing things like turning the screen off during periods of downtime to help with this (actually charges when I do this).
I'm using cheapy car adapter actually that has two usb ports and 2 cigarette ports in it and I use that with a samsung branded usb cable.
Hm yeah I'll try and see if limiting the CPU will help and if it does perhaps I'll just do that from now on.

Do you know of any other options that are wired correctly to draw more than 500ma? I think I did hear from somewhere that charging via usb is considerably slower than when using the wall charger. Do you know of any other options that would fulfill this requirement besides getting the stock Samsung car charger? Also I assume just finding a higher amp charger wouldn't work if the phone detects it as a usb charger instead of an AC charger?

The correctly wired charger will typically short the USB data PINs. iPhone charges and most generic car chargers with UBS ports don't do that. Most HTC chargers and Motorola chargers will work on Samsung phones. You need take a look at your car charger to see how much amps it can supply (listed on the spec label). The PC usb can only output 500ma max per spec. It is not enough to charge the phone while keep the screen on, GPS running and 3G connection active. Your Samsung OEM wall charger is rated 700ma. So, you need a car charger that outputs at least 700ma.
You then need to verify from the phone that the particular charger is recorgnized by the phone as AC charger. Without that, the phone will only draw 500ma max.
Donno if its the regular case of 'bad usb port'. It's happening only when I'm charging with specific car charger (1A, output 5V) sometimes its charging fine, sometimes I notice its stop charge and the icon of battery is blinking/flashing...
I've tried to clean the usb cable and port from dust, maybe the cable got some dust into it?
Also I've notice that the temperature of device goes down to 22°C when its happening...
At any other chargers (include othe car chargers and other wall chargers) there is no problem at all...
What could be the reason of this specific car charger (it used to work without any problem the last few months ago)?
High/Low voltage? Dust?
maybe other problem with my device? (Battery/something else)
BTW - when I plug the charger out when its happening its stop blinking.
could you please give us a screenshot?

From reading your post, it only happens with that one charger....any other charger works as expected?
That being the case.....it ain't your phone or the USB port/board in the phone.....
Chargers DO fail, and from my experience, dc to dc step down transformers and circuitry (the type in your car charger) have a higher failure rate than their ac to dc (mains) equivalents. ....
Time to buy a new car charger methinks

@wishmas7er - which screenshot mate? when its happens all I see is blinking/flashing battery icon, without any other message or something else about it.
@keithross39 - correctly mate, all other charger (any kind of them) works just fine.
Yeah seems like its the car charger problem, just first time i've notice it...
Thanks!
BTW - the reason of 'bad touch' while charging with some generic chargers is because higher amperage then should be to this device's battery? or other reason?
As long as the amperage is not ludicrously high or low, the only noticeable difference would be the charge time.....other than that there should be no noticable effect....

Battery Icon Flashing with Samsung Galaxy S4 Car Charger
I had the same problem charging my Galaxy S4 in the car. AC charging works fine but when plugged into the DC car charger the battery indicator icon flashed rather than showing the lightning bolt.
I purchased a higher voltage DC charger adapter, same symptom.
Finally I swapped out the USB-to-micro cable and now it works fine. I suspect that in the car the phone gets jarred over time and it wears down the micro-USB connector.
It's not just you fella........
The micro USB socket idea is (imo) a pathetically fragile arrangement for what the manufacturers intend it to do. I've repaired two phones with worn out sockets, and judging by what I am reading on XDA, it is an issue that is getting more and more common.........

So I'm experiencing the same blinking problem with my note 4. Each time the lightning icon blinks the phone vibrates in sync with it. And ithe galena with all charges. I have to keep unplugging and replugging ...and OCCASIONALLY it charges. I don't know what's the problem

I have same problem with my nexus 4.
After some googling I came across an app called Ampere.
This app tells you how much rate of current your battery is charging at.
So what i found is that when phone gets old the battery doesnt hold up charge as before. So the charge rate becomes slow. The nexus charger is rated at 1Amp and at the time of charging is able to provide low current than the rate at which the battery is draining. So the Android gets confused between charging and discharging.
For eg: if phone is charging at 300mA and draining at 350mA.
Also the battery draining rate is constantly changing. So when its greater than charging rate phone shows discharging and if less : charging...
Fix: There are three fixes which i can think ...
1) Get a higher Amp rated charger...
2) while charging close most of apps , dont play games , switch to a lower gen network like 2g , close wifi , close data which will reduce the discharge rate of the battery.
3) Get a new battery.
So I'm experiencing the almost the same blinking problem with my note 4. Each time the lightning icon blinks the phone vibrates in sync with it. It won't come on it won't reboot I've tried everything BUT replace the battery because if I plug it up it'll vibrate and blink but nothing else works. It's completely black when it's unplugged.
Anyone else had issues with their device not charging sometimes when it's plugged in?
I noticed my phone was rejecting basically every USB Type A cable and charger I had, but it also didn't charge using my Type-C PD charger a couple times as well.
I ended up turning off Adaptive Charging, and with it off I haven't had any charger be rejected, unlike before.
Adaptive Charging turns off charging during bedtime. It will turn charging back on about 1 or 2 hours before you wake up so that you have a full battery without it charging all night. I turned it off to because I just plug in, get a good charge and then unplug when I go to sleep.
What charger is best to use? I'm currently using a generic 30w QC3.0 . Guess i need a PD? Will any do or is a google one better?
Pixel expects a PPS charger with specific voltage profiles but PD will work fine if not slower.
I doubt it was "rejecting" the charger, but as noted Adaptive Charging will greatly slow the charging speed down so that a charge that normally takes 1.5 hours might take 8 hours. All of this is dependant on what time you plug the phone it to charge and what time you have alarms set (or not set) for in the morning. The idea behind adaptive charging is that the phone will slowly charge the entire time you are asleep and it will only hit 100% right before you wake up.
Personally I don't like this feature as I would rather not charge the phone over 80% whenever possible. So I will charge the phone normally to 80% and then remove it from a charger while I sleep.
Hi All,
Not sure what the deal is with the charging status on this device.
Plug in, says super fast charging, then a second later switches to 'charging'.
Tried different cables & chargers and similar behaviour, 'fast charging' (using a different brick) then immediatley just 'charging'.
Do I need some power/cable accessory, or is it actually charging at a fast speed, it tells you briefly then just generically displays charging?
Bit confused, lol, cheers!!
It just show this way but it is using fast charging anyway. If you will use bad charger and cable you will get notification Cable charging. So we have Cable charging, fast charging, super fast charging 2.0 and then they fall to just charging.
Thanks for clarifying
