Is anyone else having issues with power while using navigation in the car dock? Twice this week I've dropped my phone into the dock while fully charged, and taken a 4 hour trip using just navigation and pandora. By the time I reached my destination I had under 15% battery both times. The dock is plugged into an adapter that puts out 2.1A, and the battery on the phone indicates that it is taking a charge the entire time.
me too
I have noticed, that if I have BT, Pandora, and nav running at the same time, the draw is more than the charge, i.e. the battery runs down.
BUT
I have the att car charger, with the curly micro usb and an extra port, and a light to show plugged in. I plug the dock cable into the extra slot, and charge my plantronics using the curly cord. i tend to only pull the charger half way out when getting out of the car. I have put my phone in the dock, without plugging in the charger, and the light illuminates, pulling power from the phone. I drive on thinking the phone is charging, while using bt, pandora and nav, pulling on battery the whole time, and then wonder why my batery is so low when I get to the office.

Hi, everyone:
I just got the HTC EVO car dock a few weeks ago, and I'm mostly pleased with it. One strange thing, though - it appears that the phone's battery will not charge as quickly as it used to, if it charges at all.
This evening, I tried an experiment. I had my 1A charger connected to the EVO dock, then I docked my EVO. When I go into Settings/About Phone/Status, Battery status shows Charging (USB). However, when I remove my phone from the dock and plug it into the charger directly, Battery status shows Charging (AC)!
I haven't been able to find an answer to this problem. One thread here stated it is a problem with Froyo and the dock application, that it only allows charging via USB, but I can't corroborate that. I found another thread that said it's a safety feature, that it won't charge a hot battery, but in my testing above, the battery is fairly cool and I still get different results.
Has anyone else come across this problem? Perhaps it's just a defective dock? Otherwise it's a fantastic car dock, but I'd hate to find out it has a design flaw that borks charging. Thanks!
The car dock does charge as usb mainly bc the dock has a slightly different pin set putting the phone into navigation mode ..but also decreasing contact with the port ...

I have the same car charging problem, although I don't use a dock, or the docking application. I just cannot charge in the car. The EVO reports that it is charging (AC), yet no electrons flow toward the phone from the car, as reported by both Current Widget and SnapTurbo's widget.
I've been looking for a solution to this issue for a while. The car's power port works fine. I can plug the home charger into an inverter and plug the inverter into the power port and that works perfectly. I have tried three different brands of car charger and none work. My next solution will be to find a DC12 to USB adapter and use my regular USB cable and see.
Hopefully we can get some answers.
OK, a little more info:
I installed CurrentWidget, and I logged my half-hour commute. For one log, I had the phone plugged in the Dock. For the other, I had my phone plugged in directly from the charger. For both sessions, I had 3G and GPS on, Car Home was running and I had the navigation program open. Here's what I found:
Phone in Dock average draw: -77.419Ma
Phone out of Dock average draw: +136.0588Ma
So, my unscientific conclusion is that the dock is somehow losing over 200Ma. With Nav, 3G and GPS running, that's enough to change the phone from a charging state to a dis-charging state.
I guess I'm going to return this dock. It's a shame, really, because otherwise it's a well-build, easy-to-use dock. But if it's not going to charge my phone while driving, it doesn't make sense to use.
It's not the dock, its froyo...when the dock is placed into dock mode by grounding pin 4 ANY dock that truly places the phone into dock mode will do it...I built a dock cable when the phone launched, it worked fine..now after froyo it and the HTC dock cause the usb only charging rate as well as the 3.5 jack volume fix..(won't go any louder)
It is the suck. I'm the OP on the HTC dock now available thread, I've had the thing a long time and had it apart, its power and ground with a jumper to ground pin 4..that's it..no data wires..that's also why it wont let u mount the usb...also the suck...hope that helps your problem..

The light comes on most of the time but it still doesnt really seem to be charging it. Any idea what's up?
Swap the USB cable and use the one that came with your phone. Lots of times the USB cables are the culprit.
Don't have the one that came with my phone but I've tried a few different cables

Is the phone active during the charging time and does the phone charge normally without the dock? I've noticed that with my stock sprint EVO car dock plugged in, when used to navigate (GPS), screen on and perhaps playing music through the aux connection, the phone only holds its own. Won't fully charge, but won't discharge either and if I turn off the screen or spotify, the phone will charge, just slowly.
As the USB cable plugs into the dock, not the phone when it's mounted, removing the phone and plugging in directly has the phone charge normally.
patass, can I get a link for the dock? Sounds interesting, I might try it myself as I have the cable that came w/ my phone.
hey All,
Noticed something quite odd lately and I think my battery is on the outs - but want to confirm that what I'm seeing is not normal.
ATT Note 2, CleanRom with Nova.launcher.
Whenever I get into the car, I turn on (via NFC tag) Waze, Spotify, bluetooth and auto screen brightness.
On a 300 mile roadtrip, we noticed that my battery percentage would continue to drop even while plugged in. I started the trip at ~50% and continued to drop, albeit slowly, but not charge.
I'm using the USB port that came with the car (Audi A5) to charge the phone so I'm not sure if it's 5W or 10W or something in between. I pulled over at a shopping center and purchased a 12v 10W usb charger and the same thing seemed to happen.
So anyways, is this normal? Me thinks not, but who knows?

You are using a lower mAh charger and hense the faster discharge than the actual charge.
I do not have the specs but I think SGN2 came with 2mAh chargers... Your car's USB probably has an output of 0.5mAh.
You can get some aftermarket car chargers that have 2mAh output and that should get you charging while allowing you to use the phone at the same time.
Hmm, so I came up with another brilliant experiment.
I'm plugged in here at work using the Samsung charger running the same stuff as I do in my car and it's dropped 2% since I posted the above thread.
Try flashing a new rom
and kernel

I would have a hard time believing you are using more energy than even the lowest rated car charger could handle. I think the lowest rated charger you will find will be about 500 milliamps or 0.5 amps. The highest is going to be right around 2 amps or 2000 milliamps. The stock white Samsung charger is a 2.1 amp or 2100 milliamp charger I believe. Of course there are others that are in between.
I would either get another battery to test your problem or do as was suggested and flash again.
Running cleanrom 4.0.5...kernel it came with, and I will use Car home ultra(ends up in background), split screen with music player on and google maps running navigation, gps on, auto brightness, and Ulyses speedometer app in background giving me ground speed overlay on Google Maps. Battery still charges on my maximum 2 amp charger in my car.
A few years ago, I installed a Verizon Samsung Tab 2 in the dash of my Cadillac. I have this tied into the sound system and use it mostly for streaming music and google maps. I had it set up so that the power (cigarette adapter) would shut off whenever the car turned off. Then I used the Tasker app to detect when the tablet was not getting power and put the tablet into Airplane mode, turn the screen off, and pause any music. This would cause it to conserve enough power that it could last a long time until I started the car again. (I cannot reach the tablet's power button once it's installed in the dash). This worked fine for years. However, this tablet was so slow due to no OS updates ever that I couldn't stand it any longer.
I recently decided to upgrade to the Verizon Asus Zenpad Z8. The issue I am now having is that no matter what I do, the tablet dies when the car is sitting. I cannot keep up with its power demands. Tasker does not have the options available to put it into airplane mode. But I have gone into the developer mode menu and set it so that the screen goes off whenever the tablet is not receiving power and it goes into super saving mode during the night. It still dies. It cannot get enough power from the cigarette adaptor to charge it fast enough to recharge what it has lost when it was parked. I have upgraded to the fastest cigarette charger I could find (3A). The battery life barely moves while the car is on, it charges soooo slowly. But the battery drains very quickly when off. This means that every time I get in the car, the tablet is off and I have to pop the panels off the dash to turn it back on.
I recently tried to use a small power inverter (powered from the cigarette adapter). This caused a massive feedback loop that was unbearable (and not fixed by an inline noise filter). I then tried a true sin wave inverter, same result. Although this did solve the power problem, it charged fast enough that there would be enough battery life that the car could sit overnight and not completely die.
I had to go back to the cig adapter. This tablet is thus far, un-rootable. That limits my options with shuttings things down and limits the features available in Tasker.
If I switch the cig adapter to power the tablet all the time, then I don't have a way to tell the tablet when to shut the screen down (so that people walking by don't see a tablet in my car and break in). I'd like some way for the tablet to know when the car is off so that it can shut things down. The easiest way to do that was by making the cig lighter turn off when the car turns off.
If anyone has any other ideas, I'm open to about anything at this point. This is getting really frustrating. Thanks.
I bought this tablet because my whole family has USB-C devices. No more stupid micro USB what an abortion that connector was. At any rate at first we used USB-A to USB-C adapter cables with USB-A charging devices. I noticed right away that most of my chargers would overheat quickly or simply charge quite slowly...the charger could not keep up with the demand if you were trying to stream video to the phone or whatever. Then I bought Google Pixel phones for me and my wife and noticed that the supplied charger has a USB-C port on it and the supplied charging cable is USB-C to USB-C. These Google supplied chargers would completely charge a dead pixel phone in 20 minutes. After reviewing the USB-C standard on Wikipedia I noticed a much higher ampacity available using USB-C to USB-C devices. So for my car I bought an LM317T integrated circuit and with a resistor and a heat sink I cobbled a little 3.5 amp 5v charging port in my dash. You could also use an LM7805 if you wanted and insert a small value resistor on the ground reference if you really want the extra .5 volts. Make sure and attach the ic to a small heat sink with heatsink compound. You will need to solder your female port to a female USB-C and use a USB-C to USB-C cable as the USB-A connector on the Asus supplied cable cannot pass enough current.

Here's something you can try:
Use a different signal to trigger sleep mode, like WiFI. You could use a cheap 3G router and have the tablet connect to it via WiFi. When you exit the car take the router with you = no WiFi = tablet goes to sleep.
My phone's battery died through the day, so I plugged it to my car charger on the way home. I noticed the bottom was hot and it only charged to 2%. I plugged it up at home, and it would not charge. I plugged it to my PC and gave me "hub" issues. I went back to my car and plugged it on the car charger, it started to briefly charge but noticed the bottom where it was plugged up was getting warm, so I unplugged it. The metal from the phone charger was very hot.
I ended up plugging my charge cord into a bluetooth device and it would not charge, but it started to get hot real quick. I unplugged it from the phone and within a few seconds the metal part of that cord was extremely hot as well.
Any thoughts as to what's wrong with my phone and how to get it back to charging?
If you plugged the charger into a Bluetooth device and the bluetooth device also didn't charge and got hot, then its probably your charger.
Agreed. Were you using the same cord with each attempt?
