I have found that when charging my HTC phone (Kaiser now, used to be a Blue Angel) in my car, if I use a cigarette lighter splitter (So that I can charge another device too) that even if nothing else is plugged into the splitter, the phone will not charge properly. It seems to get enough power to maintain charge, but if I am low on batt, then charge the phone and use it for satnav while I drive, when I finish the journey, the phone has not charged.
This does not seem to be the case if I plug the phone charger directly into the cigarette lighter socket instead of via the splitter.
Knowing a little about electricity, I guess the splitter is running the sockets in parallel or something and dividing the power between the sockets?
Any ideas on what I could do? I would imagine a car battery has plenty of power, maybe it just isn't being distributed properly. I guess the splitter is possibly limited such that it can't pass too much power if only one device is connected?
All the devices I want to use can power from USB, so I am guessing that the solution is maybe a USB hub designed for car use. I have 3 items typically that I want to be able to charge, so a 4 port hub would be nice. Anyone know where to get one in the UK?
I've got the same issue with my car charger (HTC Mogul phone), although for me it doesn't matter whether I use a splitter. Where did you get your charger? Maybe it just isn't supplying enough power.
While it's true that having two devices in parallel causes half the current to flow to one and half to the other (assuming they have the same resistance), the power supplies should be more than capable of pushing enough current for each device, especially when the car is running (and you're getting your electricity off the alternator).
well I thought it could be a dodgy cable but I just got an official HTC car charger for my kaiser and am observing the same thing.
It could have been the cigarette lighter->USB converter or the retractible sync cable I used to use, I will do some more tests and see if I can work out which bit is causing the problem - it wasn't until just recently that I had an official end-to-end solution (ie one HTC car lighter to miniusb cable) so I will try connecting it up various ways, but it isn't exactly quick to test if it is good or not as you need your phone low on batt and to be driving around for an hour or two to see if it is charging properly.
Flat Batteries
Seems XDA has software to prevent charging batteries which are too flat. (Perhaps to protect internal circuitry).
I recommend this thread which has a solution:
http://www.htcwizardweb.net/node/2013#comment-3808
I made it work OK but it is a fiddly job. An external charger for these batteries would be great but I can't find one.
Good luck !
I have the same issue. The battery has refused to charge when its below 40% or so. I now carry a spare in the car, especially as I often depend on Sat nav working!
yeah I had that low batt thing happen with my BA once or twice.
Actually, now I have kept an eye on it, it doesn't seem that bad with my kaiser. I no longer use my car lighter usb adapter though - I use the HTC car charger into a 3-in-1 splitter (usb, extusb, 3.5mm audio) and from that into my Kaiser and it seems to charge the kaiser ok (albeit a little slowly) even when I have a cigarette lighter splitter also powering an RF transmitter.
So I think maybe the weak link was the car lighter to usb adapter, maybe it was outputting too little power on the USB rails.
Car Charger died
I'll jump on an old thread...
My HTC branded car charger (that I got from sending in the post card) worked fine for my Cingular 8525 until a few weeks ago. Then it got flakey and now it doesn't want to work at all.
My 8525 will still charge on my laptop connected cradle and the AC charger.
Has anyone seen any failures in these chargers?
Any recommendations on chargers that are reliable?

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..

Hey guys,
I got my brodit active car holder now for a few days and it seems it doesn't supply enough juice to the S2 while in use :-(
While navigating with navigon, it even loses charge, though it's connected .... that's really disapointing, since brodit normally supplies quality products.
Anyone else got the brodit active holder with the same problems?
boba
Not got the Brodit, but I have the same problem when using CoPilot and charging via the USB cable attached to a car charger. It can keep the charge at current level with CoPilot on, but will only charge with CoPilot off.
Also noticed if SII has less than 50% charge, it won't charge at all with CoPilot on.
Taking a punt on one of these to see if it makes a difference:
http://www.buyincoins.com/details/d...-for-ipad-iphone-4g-ipod-2a-product-2748.html
Which holder do you have exactly? Can you make a photo?
Does it toggle car dock in the S2? You can see a steering wheel in notification bar.

I was thinking exactly the same thing this lunchtime. I have the cigarete lighter active Brodit mount and - if i makes any difference - a 2004 Vauxhall Astra H. I as wondering if I would have to turn off the nice things [like satellite view, etc] on the phone for it to survive the journey. Not happy.

Is the S2 in USB AC Mode?
Take a look here: Einstellungen - Telefoninfo - Status
Yesterday I modified a Brodit active car holder from the good old htc HD2 to fit the S2. Now I have fast charging (AC) and Car-Mode.
I currently own some chargers. Not the original one, well the UK Version with no use in Austria.
A 1A HTC Charger with USB socket, a 450mA noname charger with USB socket and a no name car charger with micro usb.
The car charger and the HTC charger show charging(AC) whilst the noname 450mA charger shows charging(USB)...
It would be interesting to measure the exact mA taken by the phone...

Hi all,
Okay, I've now tried four different chargers, and I've also had the phone replaced. Today, in a last attempt, I bought an official Samsung charger.
NONE of them work - even though the phone says "charging on AC" for all of them.
The only thing I haven't tried is a different car (which I'm going to do, once my neighbour gets home).
The one sensible suggestion I've read is that Samsung have screwed up somewhere in software and the phone can't draw enough juice.
Electronics is beyond my little brain, so I don't get why the GS2 charges from my netbook (even when it's only on battery) but won't charge in the car.
And I'm not talking when I'm using satnav. It won't charge at all. In fact (weirdly) it actually DISCHARGES much faster than it does if it's just sitting in my pocket.
I've logged this with my provider (Voda UK), because I refuse to get stuck with a useless phone for the next 18 months if this isn't sorted out. It's ludicrous. If I can't charge the phone in the car it's as good as useless to me.
UPDATE:
Okay, I just tried my neighbour's car (Vauxhall Astra) and the GS2 charged perfectly. 3% in four minutes. Pretty much what I get off the mains charger.
I wish I knew about electrics but I don't. Explanations will have to come from the boffins round here.
I tell you what, though. I don't really want to get a new car just to use my phone properly
Do you have any chsrger with a led?
If the led stays dark the cigarette lighgter of your car might need a new fuse.
Which car?

You might be able to change to a higher amp fuse in your car fusebox.

Brodit mount arrived and looks great. Fit and design excellent and seems to charge as I would want.

So what charger do you guys advice? Which charger does charge the phone, even while navigating with Navigon?
I got the Brodit active charger (BR512...), there isn't a problem with charging at all.
I think the issue you got is really car related. My guess:
a) your cigarette lighter port is poorly wired -> Measure voltage at the port with a voltmeter, it should be at least 12V DC (Edit: Even if it does there is still the possibility that your wiring is bad, showing 12V doesn't mean it can handle the current this charger needs)
b) your cigarette lighter port doesn't make a good contact to the brodit plug. Check for corrosion of the contacts, dust, dirt, etc. Some ports go bad after lots of plug in / out cycles.
If you have no idea what I'm talking about here, I'm pretty sure every car mechanic can fix your problem for a small amount of money
Edit: it's very possible this plug works with other chargers and phones and still fails with the S2 charger. The reason for this is the different ways chargers convert the car's 12V DC into 5V DC. Some might work down to 7V input, some already **** up at 11.8V
I have the same problem with my GSII trying to charge it with my 12V Ipod adapter...
I just arrive from a short travel with my Citroën Xsara and i almost got lost cose the phone discharged all the time while using IGO on the phone...
I don't think this is car related because there are so many people with different cars having this problem... so... Samsung wants me to buy a new car to be able to use their phone in travels?
Hi guys, just thought I'd try to clear up a few of things:
1. All phones can use more power than they can draw. Note that the more apps you use, the more juice you draw depending on their features.
2. Not all CLAs are the same. Most modern devices will need 2amps, but the majority of CLAs on the market are 1 - 1.2amp units.
3. Your device will stop charging if it reaches a certain temperature, without giving you any further indication that it is too hot. This is a common scenario if you've got a phone on the dash giving guidance, with the sun rays beating a back. And yes this does mean dedicated satnav devices have a greater operational temperature range than phones, usually a 15-20 degree difference (celcius).
4. If the CLA is being tripped out due to poor isolation (a lot of cars suffer from this) it will also stop charging.
5. In general terms, the lower the battery level of the device, the more juice it pulls. This is why you may find you ha email no problems getting a small charge when you start with a battery at 85%, but your phone dies if the battery is 50% or less.
Hope that helps.

OK, I have no idea what the problem is. I have a Brodit active charger (the cig-plug version) for my Galaxy SII. It's not charging my phone AT ALL. There is no sound, nothing displayed on my phone when I connect it. I have the charger led (blue light) on, so I know it's working.
Things I have tried so far:
1. Asked for a replacement from Brodit. Got it, no difference.
2. Tried with a different car (I have a BMW, my wife a brand new Toyota Auris) - doesn't charge it either.
3. Tried a different no-name universal charger - it works perfectly well, the phone is charging as expected. Other things like the GPS device also work fine.
4. Tried a different kernel and ROM on my phone, still no success.
Any suggestions are welcome.

Thats strange, in the first place i thought a faulty micro-usb or charger. But you got it replaced so can't be the problem.
I have a brodit with charger too, but i use it in a different way, meaning i can remove my holder and unplug it without unplugging my charger. ( near my holder i have a small connector that i can unplug).
What i did is cutting the cable from the charger and i did put a male usb port on it ( regular male usb port) and i have a Belkin charger with a usb port, this charger deliver 1A charging current and charge my phone even when i use my navigation. ( with bluetooth and gps on).
Your phones micro-usb seems to be fine too because it charge with other brands of chargers.
Your BMW delivers enough power i guess at your cigarette lighter plug, because it doesn't charge at the Toyota either and both not delivering enough power would be coincidence.
Anyway mine works perfect the way i did it and if i can remember it worked too with my original plug attached too. ( though the original one doesn't provide enough power sometimes to keep it charged while using navigation).
The only thing i can think of is that there is some stress-pressure on your connection between phone and holder connection and that one pin isn't connected properly, with the universal charger you only plug the micro-usb plug in your phone and the micro-usb plug can adjust freely to your phones micro-usb port.
Try to wiggle a bit with your phone when in the holder and see if the power comes on. Or try to connect a little device on your holders micro-usb port ( if you have something small that charge over micro-usb) and see if that works.
Hi there everyone,
I have been trying to get my Nexus 7 2013 installed into my car seamlessly without problems since December 2015. I have Timur's Kernel v4 (6.0.1) running on it, and it was working flawlessly.
However, I decided that the no battery mod needed to be done as I just could not leave that battery inside a hot car - way too risky.
So, I did the Kevdav no battery mod - with success.
However, once the battery connection was receiving 5v via a usb car charger the OTG cable connected to the tablet's mini usb port would not wake/suspend the tablet properly. It would wake it up, but once it was awake the little battery icon at the top would forever show that it was 'charging' and once power was cut to the otg y cable / mini usb, it would not suspend (would still show as charging).
I did research, and bought a Drok DC-DC step down converter. I lowered the voltage to the battery mod connection to 3.7v (and tested up to 4.7v) and this alleviated the problem of suspend/wake. I think since the original battery gave out less voltage then the otg/charging connection, this needed to be replicated in order for the otg to work.
However, I now have a new problem that I cannot seem to fix. This problem only seems to happen in the car and does not occur when testing it in the house using normal wall chargers.
For clarity, this is how everything is wired up in the car.
Nexus 7 battery mod side of things:
Nexus 7 battery terminals > 22awg usb cable > drok dc dc step down power supply (this board has a female usb port for output) set at 3.7v (tested up to 4.7v) > input is connected to car's constant 12v connected directly to battery on a fused wire.
Nexus 7 mini usb port side of things:
Nexus 7 mini usb port > usb otg y cable > mini usb cable > 2.4a usb car cig adapter hardwired to car's switched 12v accessory wire.
The link to the drok dc dc step down is this - https://www.amazon.co.uk/dp/B01FDBY66Y/ref=twister_B01GO268W6?_encoding=UTF8&psc=1
I turn on acc ignition to send power to the otg connection. It'll power up. However, if left in standby overnight the tablet won't power up. If I physically press the tablet's power button it'll wake up, show the wake up animation, and react as normal (including any subsequent power downs). However, if I don't press the power button and I turn off the ign again, an icon on my car's instrument cluster will be faintly illuminated - this is odd behaviour and should be completely out. When this is the case, if I get out and try to lock the car the remote central locking doesn't work.
This light will go out if I physically disconnect the otg y cable from the tablet, and low and behold the remote central locking works.
I'm no expert on electronics and such, but it seems to me that power may be flooding back into the OTG connection from the no battery mod power?
Does this make sense? Sorry for the long question, but I was wondering if anyone had any experience with troubleshooting or any advice? I've this one problem and then I'm set but I just can't seem to figure anything out and need someone's advice who is in the know rather than take wild stabs in the dark using my own logic because if I do the latter, not only will I waste money on needless components but I'll more than likely break something. I've read stuff about diodes or something in order to regulate power flow but I'm not even sure I'm using the correct terminology here so if anyone can tell me I'm onto something here or I'm talking complete nonsense then anything is appreciated!
I did search these forums and google but I really cannot find anything that is similar to my problem.
Thanks for any input guys, whether it be any tips on what I'm missing or what I need to change (software or hardware, electrical, etc) - it's all very much appreciated.
Antony
Edit: so sorry I think I posted this is the wrong n7 2013 sub section. I can't delete the post but if a mod could please kindly move it to the relevant forum I'd appreciate it. Thanks!

Hi, indeed, and your "2.4a usb car cig adapter hardwired to car's switched 12v accessory wire" requires a small mod to prevent the power feedback. It needs an extra 1A+ diode connected directly to 12V input. You could modify the adapter's PCB or simply replace the fuse's internal wire with a diode where its cathode goes to the spring and its anode to 12V input. Or just place the diode somewhere along the adapter's hardwire. $0.16 1N4001 is good enough ([email protected] is OK for [email protected]).
Not sure if thread is still active but I also have the same symptom with tablet turning off completely overnight. I am running constant 12v to 3.7v dc to dc on battery input and car adapter 12v to 5v on microusb cable in. Tablet will work fine with on and off but after car is shutdown for the night it will not turn on in the morning. It shows me battery charge icon only. I dont have diode installed either. Not sure if thats the cause. Anyone know why it would completly shutdown overnight?

Hi there,
Been a while since I posted on this thread but just wanted to update on what I have done so far.
Since my last post, I don't have any issues. I placed a diode as mentioned above on the +12v for the accessory power. This seemed to have fixed any back flow of power.
Concerning the power off over night, I'm pretty sure this was something to do with Timur's kernel. I forever had issues with that thing - eg, suspect and wake issues, accessories connected to my usb hub..
I switched to a stock version of android 6.0.1 - MOB30X if memory serves... and installed Elemental X version 5.16. No issues with this setup what so ever.
Huh.
I run my Nexus 7 on my car with the battery, mounted just above the dashboard, with direct sunlight exposition and no UV film on the windshield. It's been a whole year without issues, thank God.
https://i.imgur.com/cPNhDDc.jpg
I live in the Northeast of Brazil, where's 30C to 40C through the year. Sometimes I come up to the car and the tablet shut off due to the heat.
Battery still lasts wonders and there's no signs of damage.. yet.
Is it really adamant to remove the battery, or is it just a precautionary measure?

You better have more luck.
My nexus was put under the dash and was fine for around 3 years. And it became expanded in just 2 days, separating the screen and the case. So I have urgently remove the battery.
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.
