[Q] loses 450mAh while using GPS - HTC Rezound

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
Rezound

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.
Rezound

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.
Sent from my Galaxy Tab 10.1

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.

Car charging problem with Touch HD

I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.

[Q] Atrix Car dock charging problem?

I believe that there is an issue with charging performance in the Atrix car dock. I'm using the OEM Motorola ECOMOTO Rapid Rate vehicle power adapter (850 mAH) with dual USB ports. You can tell this USB charger is a good product just by the weight of the thing! A test charge in the Atrix car dock began at 7:45 AM and the phone's charge was 20%. At 9 AM 30% and 10:30 AM 40%. This is obviously nothing like the wall charger so it made me believe that the phone was powered by the charger while docked but only receiving a trickle charge. Connecting the phone directly to the USB car charger (without the car dock) using a stock USB to micro USB charging cable, at 8:00 AM the phone was at 20%, 8:20 AM 40%, 9:00 AM 70% and 10:00 AM 100%. What a contrast!! So it appears that there is an issue with charging performance while in the car dock. I've reported this to Motorola and hope that they can reproduce and address. How about the rest of you, what say you all?
Mine charges fine. I have the moto - 2usb port charger and it powers the phone in the dock just fine (mine is Y shaped and ships with the MotoBranded car dock, not AT&T).
Mine charges just like the wall charger - both put out 850mA. If I am running Nav in the car dock, and screen is on, it charges slower - but this is to be expected.

I find when driving around during the day with the screen always on, taking the occasional call and GPS/Navigation running most of the time (not sure, just love seeing my KM/H sitting up there helps keep my heavy right foot off the go pedal) that my battery slowly slinks up in % almost like it's not charging due to the load I have on it.
old thread but..
Hello
I know its old thread and no one is interested anymore but I found out that Atrix is giving power back to the vehicle when connected to the car dock.
I have a Cigar lighter slot hub with an LED indicator. The LED remains glowing when I turn off my car and leave Atrix in the Car Dock. I found out that ACC are having power until Atrix battery is empty.
Even if I unplug the HUB from the car, LED remains glowing, but battery drain seems not that high than connected to the car.
Once I remove the Atrix and put it back, LED is not glowing again, so I think it has something to do with the Car Dock and the Atrix software. (not sure)
I'm trying to make a work around with relay...

[Q] My Photon's battery won't charge from USB in car

Has anyone else had this problem? I plug my Photon into a USB power adapter plugged into my car's cigarette lighter and the phone displays the message that the device is charging but the percent of charge continues to decline. I have changed USB adapters and USB cables but it still happens. If I use an AC adapter and the same USB cable the phone charges correctly.
Is it a software or hardware problem? I was unlocked and rooted using several of the current custom ROMs and the charging process in the car worked then. When I re-locked and went back to stock and re-rooted then this happened.
i am having the same issue as of yesterday. Did you ever find out what the issue was?
im guessing that the car was off and that it was a foreign car...
Numerous issue could actually cause the same symptoms, Apps/games in the background... failing alternator, failing cigarette lighter, failing car adapter...
car not running while its charging could also cause this issue depending on charge level of the battery and the volts of the battery...
What you'll need to do is eliminate the possibilities..
Try with the car on and the phone on...
try with the car on and the phone off...
try with a different adapter for the car...
try with a different usb cord...
try with a magnum 44 aimed at it...
Try with a different Car is also another good option.
Ditto.
I am having the same problem.....worked fine before I unlocked/rooted. Anyone else have a suggestion?
I have the same issue with the incar charger and using a computers usb port to charge my phone..(doesnt charge when under load ..ie-dowloading something)...i think that it is the charger being underpowered..example..
Stock a/c charger puts out 850mA
Most computer usb and standard car usb chargers only put out around 500mA
Sent from my MB855 using xda premium
Mine charges very slowly in the car. The other day, I plugged in at 32%. Drove 30 minutes to get home, and it had only reached 37%. Plugged in at home, and within 10 minutes had well over 50%, even though I was actively using it then.
This is on stock rooted, btw.
The stock drivers must use a very conservative power draw when plugged into a relatively low-output power source. By contrast, the power draw from a high-output AC adapter must be quite aggressive, because it charges more quickly than other phones I've used when plugged into AC.
It did turn out to be caused by the car charger being underpowered. I went to BestBuy and bought a "high capacity" charger and all is good!

Which specific car charger did you get? I'm having the same problem too!
The Photon needs at least 850mA charger to get charge currently. Otherwise it charge slowly or not charge at all.
Can anyone post a link to a specific charger that is working great for you and charging fast while in the car?
has any one who got charger working ? can anyone pls post the link to product

Battery actually drains when using car charger with GPS Google Maps Navigation On

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.
Sent from my SGH-I777 using XDA
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.

Same here. Glad to hear it is not just me. I just got off with NA HTC Tech Support. There official stance is that they do not recommend or support using any device other than the official charging cable and plug in device. They went as far to say that they do not support charging in the car. I just about flipped my lid on the phone.
Here is the link to their site: http://www.htc.com/us/support/howto...783&p_name=droid-dna-by-htc-(verizon-wireless)
"Only the power adapter and USB cable provided in the box must be used to charge the battery"
I was told by Verizon that this was just a scare tactic, while HTC says I am not getting the right charge and they have no answer since they do not support DC charging in the car. Any info people have is appreciated. It works fine with Hard Wired DC -MicroUSB, but not with any USB Plug in.
Any apps that would help me measure the amount of charge it is getting?
Thanks in advance.
What are the specs on your car charger?

So odd that they would do that, especially with the power draw of the phone. However you can charge using the battery packs?
My car adapter is a Macally USB car adapter model carusb10 output 5v/2.1 amp x1 500mA x2.
As for my house adapters the RCA 2 port USB wall adapter. 2.1 Amp x 1 or 1000mA x 2 I believe.

Everyone with a stock DNA unplug your charger and flip it around. As in flip the prongs. It should give you this message even with the HTC supplied one. Or try this. When you use another charger and it gives you that message unplug it and flip it. It should straighten out. I dunno. Something about the way the power is drawn.

I have tried several different USB adaptors, from Razorfish(BestBuy), Belkin single USB input 2.1amp, innocell (RadioShack) dual SUB 3.1amp. Same problem on all.
On the other hand, any direct Wall connection with USB cable attached seems to work fine.
Also, I have the Motorola p4000 battery backup and when I plug that in, it also works fine and views it as AC.
Swapping the pins didn't work for me, same issue. Its a pita for me especially charging in the car because when using phone for navigation it charges so slow that it can't actually charge my phone and my battery decreases. I've went the route in the car I use my nexus 7 charger connected to an inverter.

From my phone conversation with Seth from HTC Support, the slow charging warning is due to the update because the update incorporates the faster charging feature that qualcomm & htc have referenced too recently (can't remember what its actually called). The phone has a new type of charging setup that makes it charge faster than some other phones.
Unfortunately some chargers (wall/car) dont supply enough voltage to activate the charging feature so while the phone does charge fine (it charges at standard phone charge rate) it cannot charge at the faster rate due to the charger.
He states that this will not harm the phone and ther phone will charge fine and it a normal time. You can disregard the warning. For those that like the faster charge rate, you have to use the right charger/cable.
Before the update our phones were mostly charging at the slower rate and that's why most didn't see a warning unless the cable being used was below the standard rate of charge.
Hope this helps

Why are there so many problems about this thing lately even me, I experience this most of the time
When I use the Best Buy 2.1 amp wall charger I still get the message.
I'll need to find my oem wall charger.
So far every one I have gives this message.
I haven't seen this message at all on any of my charges but I haven't charged in the car yet. My battery usually lasts for more than the while day so I just charge at night.

Well with the faster charging enabled it does charge pretty quick especially using my nexus 7 wall adapter, even with my Nokia Qi pad. But man that last percent takes a while.
As of now I'm using supercharged hatka ROM slim 3.0.3 and getting good battery life. Even in the middle of nowhere where 75% percent of the time when I'm in the plant its searching for signal. I'll leave work after 8 hours and still be at 60%
Guess you can say its the only negative I have for the phone. Trust me the battery life is much better in the plant then my old bionic. I use to have to change the standard battery after 4 or 5 hours as it was completely dead.

Last night I received my daughters replacement Rezound from the warranty company. It came with a 1 amp wall charger.
I plugged it into my DNA and did not get the notice of slower charging and it charged quicker than I've ever seen it.
Too bad my 2.1 best buy one won't.
The quick charge capable chargers must output just slightly higher voltage to trigger the rapid charge mode.
I'll experiment some day and see.
This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.

I kinda figured it was something with the pins if I wasn't voltage offset.
I did find that one of my car chargers from best buy runs in quick charge. The cable I fixed, rather than using a usb cable in a slot on the charger.
The best number 2.1 amp wall charger uses a data type cable.
Maybe I'll check into shorting the pins on that sucker to get quick charge mode.

The phone is doing more than checking pins now. I have a 2.1 Amp dual charger with pins shorted and get the warning. It happily charged in AC mode before the update. The charger can also charge a nexus 10 at 2 Amps. I'm guessing the kernel devs will have to locate the source of the warning. I thought the resistance between the data pins might be the trigger, but there is no difference between the HTC charger and my dual charger. It does seem my car charger is unaffected.
I have found that to trick the phone into AC mode you have to short the the actual cable. Hence strip the insulation off the wires and short the data wires together. Has worked for me on all my chargers.

This message does not have to do with the update. I have still not updated my DNA and have been struggling with this for about 6 or 8 months. I am on 2.08. The issue has continually gotten worse since the first time I saw it. At first it would just appear about 1 in 10 times I plugged it in to a car charger. It then got to the point where it would only not show the message with a certain car charger. Now it is showing it on the one car charger that works, but if I mess around with it and unplug and replug it a few times it will finally charge normally. The last few days it has started showing the message on the OEM charger. I have cleaned out the port on the phone and cables quite a few times now, but it doesn't help. I found that doing that only helps if it gets really full of lint and the cable rocks in the port causing it to loose connection if you move it, but it does not change the slow charging message at all. The phone is also definitely not charging at full speed when that message is shown. If I have it plugged in and it shows that message my battery actually drains if the screen is on. With the screen off I only gain about 10% per hour. I am not sure where the issue is, but I think it is different in different circumstances. In my case I think it is the phone itself, but from what I have read about others experiences it seems their problem might be the charger/cord. I hope this gets sorted out soon.

It could be the charging equipment your phone or it could also be the power source not providing enough power to the device for it to charge fast so it charges slow.
