Hey everyone,
Has anyone found a wireless car charger that will charge the phone while it's in use, say streaming audio or using the GPS? I have a 15 watt wireless charger in both of my cars and my Pixel 6 Pro will not charge when it's being used. The phone actually discharges, albeit at a slower rate than normal.......it's annoying but I'm wondering if it's because it needs a 23 watt charger like the Google Stand 2. Hoping to see if anyone's found anything like that out there.
Thank you
Phones aren't designed to charge with the screen on. The phone's power controller ramps the charge current down automatically to protect the battery. The current draw when in use is too unpredictable and it's also generating a lot more heat when both are in use.
Charging in direct sunlight can damage it.
It may charge normally if the display off and you're listening to music ie with PowerAmp on bt.

On a drive to NYC a few weeks ago, I was able to charge using an original pixel USB a to c cable plugged into cars USB port. It was 2021 Kia K5 (optima). It charged while I was streaming music via Bluetooth or Android Auto. Mostly streamed via Bluetooth. Connected via Android Auto caused massive heat issues that I did not experience when music streamed via Bluetooth. (Different issue).
The short is, it charged, but not quickly.

Yeah, wired it will charge without a problem regardless of what the phone is doing......it's only wireless that's the problem.

Hello,
I went through two car chargers and found out that they are not really charging, or if they are its very super slow. I also found the same thing happens when active sync is on. I know on kaiser there is an option that enables/disables charging, but no option exists on AP3.0. So, is there a trick to this or what ?
Thanks.
I have found that you need a specific charger for the Advantage to get anything above trickle charge. On an Advantage, trickle charge is not enough to charge the device whilst it is in use i.e. it will still discharge even if a little more slowly. I initially used an HP charger from another device with the Advantage in my car and this is exactly what happened. I got a proper one for the Advantage and the device charges without difficulty even with all the radios, GPS, etc. on. This proper charger was not HTC badged but was designed for the Advantage. I am sure it is something to do with clever circuitry in the device or the charger that switches charging to trickle if it doesn't recognise the device it is connected to.
Hope this helps.

I believe you need to make sure the charger puts out 1.5 Amps. Somebody know if this is correct? My Dell Axim needed that much to charge and run GPS.

Hi there,
I bought the charger in the following link:
http://www.easydevices.co.uk/pp/HTC_Accessories/HTC_Advantage/HTC_ADVANTAGE_CAR_CHARGER.html
Cheap, and worked perfectly. I also bought the car mount from here.
no wonder, why my phone seems never to charger
I just use an inverter and the normal adapter with mine Cost me £20 a couple of years ago, but means I can charge my ameo, laptop, phone, or any other device I choose using standard charger. Saved me loads in the long run
the designed charger for the Ameo is 1 amp, a usb car, charger will only be about 0.5 amp, this is probably why its slower. I can charge my niki no problem, but my ipaq and ameo take all day in the car. I think inverters are on special at maplin at the moment. probably a cheaper way for me to charge everything in the car.
I had this problem and bought the following charger, it works a treat !
http://cgi.ebay.co.uk/2-AMP-IN-CAR-...photoQQcmdZViewItemQQ_trksidZp1742.m153.l1262
sometimes if your charger is aftermarket it dosen't work. happens with me with mp3 playerz too
guys the charger has to be 2 amp and better for u to maintain a charge while running everything (gps, bluetooth, wifi) especially if u get hsdpa signal. Oh this is my first post ever from the Advantage.

I actually disagree, I can do all that while being plugged into a regular electric outlet and the output rating for that charger is 5V 1Amp. So a 1A Car charger will do just fine.

Hi
I Disagree, Because i have bought two car charger with 1Amp both did not worked. Then i bought a 2Amp car charger it worked perfectly.
Therefore i think it will need 2Amp car charger to charge and give power to GPS, Bluetooth, etc. 1Amp may charge your Athena but it need to switched off(put into standby)
Thanks
This question has been discussed before in this forum. Look at this thread.
Put special attention to post #5. It seems that HTC uses one pin of the mini-usb connector (it has 5 pins while standar usb connector need only 4) to differentiate between charger and sync.
If the charger does not have this pin configured correctly , the athena thinks that it is a connection form a PC and does not start the fast charging.
Other option is to use a special adaptor like the one from PPC Tech (PPC Techs HTC Advantage Lil Sync DUO Mini-5 USB Adapter avaliable on expansys), that allows you to enable fast charging with any charger (minimun 1A). I have used it successfully with several car chargers.
Reminds me of this discussion http://www.modaco.com/content/HTC-Typhoon-Variants-Typhoon-MoDaCo-com/115090/Car-Charger/
Still doesn't charge enough even w/ HTC charger
Yes. The pin configuration is different for the Athena. Yes, it needs higher amperage to charge. However, even when taking all these things into account, there's still a problem.
I bought the HTC car charger precisely to avoid the problem of undercharging / pin misconfiguration. Yet, I still have problems. Whenever I drive long distances (4 hrs +, vacation, etc.), I generally have the gps running along with bluetooth for my ear piece (in case of phone calls), and I have an mp3 player going for tunes (running off the MD). Since it's generally a bright, sunny day, I also have the screen at full brightness (otherwise you can't see it at all.) Even with the HTC charger which is listed as the one designed for the Athena, my unit will die within 4 hours.
I realize that this is alot of juice, but it still annoys me that the charger can't keep up with the unit it was designed for. I imagine it wouldn't last that long if I had the gprs and/or wifi (not that I'd have wifi going while I drive anyway) running, too.
My question is: Do you think it's the screen or the MD which is sucking up all the juice? I've taken to letting the screen shut off (an option on many mp3 players), if I'm on the freeway and don't need the gps for a while. But to be honest, I haven't taken any really long trips to test this approach.
BTW, it's not a problem with the charger. I've got 2 of them, and the same thing happens with both.

I don't have problem like yours. I always have my backlight adjusted to the brightest. I keep all my applications on MD (which means it's spinning most of the time). With GPS running and music playing, my device will give charged to the fullest and stay that way very very quickly. I use the standard HTC charger. Only thing is I don't use bluetooth, so I'm not sure how much this would influence it.
Don't know what the current is, but my Brodit Active mount charges my Athena quickly even with everything turned on- used mainly for Sat-Nav with screen on full bright/ no sleep during day.
Trickle charge from the PC USB takes forever!

I have the same experience with the Brodit.
I’m using the supplied HTC car charger, for an hour journey,
with only backlight full and GPS it charged but very small increment.
when using my phone in the car, i have the phone stream bluetooth to the cars stereo for audio, and navigation, i used the headunits built in usb to charge the phone wilst doing this, and noticed that at the end of a 4 hour journey, the batter had drained from 98% to 23%. So i bought a samsung in car charger and spent hours installing it with now wires around the front (im very perticular about this) and im still on a negative charge. Im running cognition s2 v1.31, and using poweramp for audio (only one that seems to work with a2dp) and copilot/google maps for navigation. When i run these programs, if i hit task manager it says there only using around 14% cpu each, so why on earth would it be getting a negative charge?
How about if you try and use none or maybe just one function of phone whilst on charge cable and see how battery performs.
Next check I would is to use charger in another car and see if the problem is in the hole in the car where you put the charger.

Is the display on all the time? That's usually what drains the most battery when combined with navigation.
This phone consumes too much power for running and charging in your case. Ordinary USB chargers use to provide no more than 500mA. It's not enough. You need much more. Just to try something more powerful - like iPhone 4 usb car charger. Probably it will solve your problem.
Well, ive gone and bought a charger rated at 1000ma, and it doesnt loose as much yet its still a negative charge, he screen is on consantly. After more heavy testing, using pwer amp only streaming audio was fine, it charged pretty quick, using google maps only, it charged, not as quick but it did, same with copilot, what annoys me is i came from an iphone 4, and was able to use tomtom as well as streaming bluetooth and it used o charge pretty quick, and never get nearly as warm, im so contemplating selling the sgs2 nd going back to iphone
Its already been documented. This phone pulls more power than the charger supplies. This is limited in the kernel so nothing you can do other than not use the phone that hard.
Hi Guys and Girls,
I was using the Copilot Premium on the S2 in the Car yesterday and it was plugged into the car via a car adapter with usb port. The battery completely drained and the plugged in USB was charging the phone but you could not run the phone with the Sat nav on as it kept switching off.
Is there is a way of powering the phone within the car or is to do with me using the samsung USB cable as I noticed that it recognise the charging process as USB instead of AC? My Touch HD worked with Sat Nav and it was charging the phone as well. Is it something to do with my settings as I find this a strange issue.

Yes - it's to do with the charging process status. USB charging doesn't deliver enough power to maintain battry charge - especially when using power-hungry apps like Co-pilot.
I bought 2 car chargers recently - cheapos from dealextreme, one a Moto-branded one - and was lucky that both are seen as AC rather than USB when plugged in. I recently used Co-Pilot for about 4 hours and the phone charge was maintained.
I'd say your options are either to buy the official Samsung product or take pot luck with a cheapo alternative.
Same story: bought first Energizer charger, that was hit-and-miss. Then got an official Samsung one, no problems at all. Get the official one, it costs, but it's quality.

I had a similar problem, tried two different adapters with 700mA and 2100mA DC output rating. 700mA seemed to work, but 2100mA was much better. I was able to stream tunes over my cellular Data to my car over bluetooth, while on the road using Google Nav, with the occasional calls.
Cheers!!!

Thank you for the response to my query. Much appreciated. Now I have to find a new adapter.
Hello there,
I bought Samsung's MHL to HDMI Adapter (http://www.amazon.com/Samsung-MHL-HDMI-Adapter-Packaging/dp/B005LGUDKK/ref=pd_cp_cps_1) for my at&t SGS2, video and audio worked on my HDTV without hassle, but it did not actually charge phone's battery. when it was hooked up it kept 'rising bar' on battery icon in notification area and I was under impression it's truly charging as well playing the video on my TV, but it showed 30% batter warning that's when I realized it's not charging but faking to show charging!
Is is normal or abnormal, but I read in wiki or somewhere when it's hooked on MHL to HDMI Adapter/dongle SSGS2's designed to charge the battery as well, I need to your help to determine if I have a faulty one or I should turn on/off anything on phone!
Thanks in advance!
It will only charge your phone if the TV is a MHL compliant TV. I don't think any TVs on the market are compliant yet.
There should be a spot on the adapter to plug your charger into. That is the solution for non-compliant TVs. Did you plug your charger into the adapter?
Sent from my Galaxy S II (i777)
Thanks quarlow for quick reply. Yes I indeed plugged the charger into Adapter in order for it to work, that worked flawlessly, but the question is why the battery icon on my phone was showing 'charging bar' while it was not actually charging, that's mysterious.
My TV may be not MHL complaint as it's 2 yrs old already, but MHL complaint TV's don't need the MHL adapter be powered by external chargers, if I am right.
Thanks!
I too have an MHL adapter but it isn't the official "Samsung" one, but it will charge the phone overnight, but I've never left the device plugged into a tv and the adapter for an extended period of time.
I imagine that the adapter needs to draw power to send an image out to the TV, and the phone simply assumes that a charger is plugged in but rather than actually getting a charge the power is being diverted into the MHL adapter, and maybe a little bit is going to the phone but not enough to offset the drain of displaying an image on an HDTV.
I'll give it a test drive tonight and see if I get any different results, but I bet I have the same result.

From what I can tell the stock charger is only 700MA and will charge the phone slowly when not in use, however if it is inuse I am sure it will only be able to keep up with the power used.
I use an HTC charger most of the time it is a 1000MA charger and seems to be a bit faster. I have not tried this with the MHL connector tho.

I believe this is your answer as well. I did not have the opportunity to test drive the MHL adapter last night, but what I would suggest is turning off whatever you aren't using while streaming. Check out the link below, and the last review for a similar problem from another MHL adapter, although MHL allows charging I imagine if you read the spec on it (the tech spec), it probably only supports 500 mAh max. Although it costs $100 to read the draft spec (which is stupid).
I will find out if I experience the same drain as well but I imagine what is happening is the Wifi/Data connection is draining faster than the charge is going into the battery, which is probably why standard use doesn't cause a problem. However streaming coupled with whatever else is going on is probably the culprit. So I'd suggest if you are going to stream anything while connected to disable non essential services (Sync, other data connections, bluetooth) and clear RAM so only what you want is actually running.

So you mean if phone is hooked up with MHL adapter while it's not actually streaming , the battery percentage should go up (meaning charging) like 8% ->to 9% -> 10% ? I can try this.
I know the MHL adapter will charge your phone if you aren't streaming, I had mine plugged in sent text message, watched a video clip I shot, looked through pictures, and left it plugged in. I also used to charge my phone via the MHL adapter (charger into MHL into phone) regularly but the charger kept popping out of my adapter if I checked my phone.
I'll look into it more this weekend and get back with you about it.
Can confirm this is indeed a problem. Would recommend under clocking the processor
Until it's unbearable and try again.
My processor is oc'd on demand but it drained it really fast. Probably a glitch in their version of GB.
Sorry I don't have better news!

Thanks Guys!
I did kinda experiment, MHL adapter is indeed charging the battery while streaming, but battery drains faster than being charged, this is the outcome.
1. I plugged the phone while it's not streaming ..battery percentage increased from 78 ->79->80% and so on.
2. I took the phone off the MHL adapter and played the same video (flash based) it drained 10% of battery in 20 minutes.
3. I hooked the MHL adapter/charger and streamed the same video (flash based) it drained 5% of battery in 20 minutes.
I would like to conclude, MHL adapter charged the battery, but flash based video streaming drained the battery faster than the rate in which the battery was being charged.
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.
