Hi,
So I got a new car and I'm testing out all the ways to connect my phone to it to share music, data, and charging. Been having a lot of issues with various parts but this question will pertain to my understanding of USB-C.
I had read that the USB-A ports in this particular car (Mazda 3) are only pinned in a way to provide "dummy" power. If I understand this properly, there isn't data pins hooked up to the port so the phone can decide how much juice to pull so it just outputs at .5 instead of anything higher. Meanwhile, I'm understanding that USB-C can actually push power in two directions kind of like osmosis. And this is why some power banks require a special ritual to make sure power goes from the bank to the phone at some point or you end up discharging your phone into the bank.
What I seem to have run into sounds a bit like this. Under the same conditions of driving into work (half hour) with BT streaming and screen off for the phone. Plugged into the 12V outlet using a Belkin charger, phone fast charges as expected. Plugged into the car's USB-A (tried two different cords too), I was losing 1-3% battery. I just figured the incoming charge wasn't keeping up with the power consumption of the phone.
This morning, I decided to run a control test. Same drive, BT streaming, started with 100% power. Got into work and expected to see at least 1-3% drop. There wasn't any. I still had 100% and did so for at least another half hour of listening with standard headphones plugged in.
My only guess is that the phone is deciding to push power the other way? Any thoughts?

I read somewhere (but cant find the post now) that its suggested if the XDAII is in the cradle and connected to the PC via the USB cable, that you don't need the A/C power connected from the mains.
Is this correct, will the USB supply plenty power for charging?
Power consumption seems high, got xda today, charged for 3 hours then started to play. Was at 100%, but after 20 mins, it had already dropped to 85%. Maybe thats normal
Cheers
Battery life initially is not very good, but it improves over time. The consumption you describe is high, but not much higher than normal. It will improve slightly, I think, depending on what you're doing in those 20 minutes. :wink: After a day or so of moderate use (some calls, some screen-on, occasionally Bluetooth) my battery usually sits at around 60%.
You're right about the USB question. Mine charges just fine from the USB cradle without the external power cord connected. It's a good idea to keep the cradle plugged into the PC directly and not through a non-powered hub to ensure that there's enough juice for the XDA2.
The XDA2 charges much more quickly if the screen is off when you're charging, and slightly quicker from the power cord than the cradle.
Lovely Jubly, charging without the need for an extra mains wall socket!. Works fine off the USB. Could always take the mains charger into work now and use it there.
My new M3100 is great, apart from one thing. I seem unable to charge it using any of the three in-car adapters I have that worked a treat with my Prophet.
Anyone know if this is an issue, or just specific to my M3100 (which appears to not be charging properly even when on USB or mains adapter)?
Cheers,
Sam
i have tried 2 different USB car chargers and neither have worked. Last one was 1A but still no joy.
Did you drain up the batt? I mean, was it full discharged when you attemped to recharge it? I have the same problem, no way to recharge it, at least the orange light doesn't show up.
If i try it at home, no prob. But what with a usb? no way
There are issues with some car charger USB connections.
I do not suffer this problem because I find it very useful to have an "inverter" permanently in the car. For those that have not seen these, it is a device that converts the battery voltage to mains supply voltage. This allows you to plug in as if you were at home. Handy for your hermes, laptop, phone etc etc without the hassle of special in car setups - just plug in with your normal mains plug. Most of these devices just plug into your cigarette lighter socket, although I have mine permanently wired in - so I also have the socket still available.
here is a UK example but I imagine they are available for all countries:

There is a known issue on car charging where the device will only charge when switched off. If this is your problem see the wiki here or my link below.

I've had that problem too. Strangely enough, restarting my 8525 gets the car charger to start working
try powering off your unit, it will get the orange light. Turn it back on after 5 mins and the charging will hold. not sure why.
I was having the same problem as mentioned above with a usb car charger that came with my GPS, however I just received my car charger from HTC FINALLY! With the HTC car charger and home charger, I have no issues charging the Hermes where I sometimes run into problems with say a generic motorola or igo power adapter - these sometimes require me to restart my device before charging begins.
By the way, I am going on a trip where I'll be away from power for 4 days ... can anyone recommed a portable cell phone charger that runs either off of AA batteries or solar power?
I think there is another thread about this somewhere, but I don't have time to look it up. I've had this same problem with several chargers that worked fine on my Cingular 8125 (HTC Wizard). History is that there is a firmware issue on the TyTN that checks for a data pin in the USB interface coming from the charger, and if it doesn't have the right voltage on it, the phone doesn't charge. When you totally power down the device (holding down power button for a while and then hitting yes to the power down question), then the charger works. It's when the device is in standby that it doesn't work right, because the firmware checks for the pin to be correct, doesn't find it, and disables the charging circuitry.
Hey Guys,
I have a query regarding charging my Hermes / 8525.
If I plug the phone into a wall unit, the orange charge light immediately comes on.
If I use the phone, or receive a call the phone continues to charge.
Once the phone has been used the phone/screen stays on.
When I plug the phone into my car adapter, the phone doesn't begin to charge until the phone goes into sleep mode. But then when I go to use the phone it stops charging. So if the battery is on it's last minutes, plugging the phone into my car adapter does NOT let me continue to use the phone. I have tried 3 different car chargers.
This week I bought an XTLINK Bluetooth Cell to Landline Converter. This is a great little box, and I love that once I walk into my house my cell phone rings through my phone system. Call Clarity is great.
But with the Bluetooth link active constantly the battery drains like crazy.
So I purchased a desktop charger unit. It arrived today. You can use it to charge the phone or with USB to synch the phone. So I plugged in the wall adapter to the cradle, and the phone only charges when not in use.
But when I hook up the cradle via mini-usb to my laptop the phone goes into constant charge mode - but it's doesn't stay on after being in use.
Can someone explain to me why the phone has these different charging modes ? Is there something I can do to change a setting to make the charging more consistent ?
Thank you,
Dave

no one else knows about this ?
I have the same problem with USB charging in the car when I was running vp3G's Rom. Now I switch to Crc's Rom and the problem is gone.
But my phone would stop charging if I use my GPS software thru bluetooth and bluetooth headset. In that case I just reset my phone and it would charge normal again.
I have seen this too. I don't know the exact details, but the phone checks the charging current when it is on, to see if it's within a certain value. If it's not, it stops the charging circuit to protect the battery. That's why it works when it is asleep. You'll need to buy a car charger specifically designed for the Hermes.
Yep, there is a long thread on car charging on the forum. Like the other uses says, either buy a HTC official charger or have a look at the other thread about soldering pins 4 & 5 together on the USB connector.
I have a generic car charger from a local electronics store that does not have a problem charging whilst talking over a bluetooth hands free and navigating using a
bluetooth gps receiver, however, I am using one of CRC's roms so that might be why.
The only thing I have found is that if I leave the charger plugged into the hermes when I start the car the hermes stops charging and will not charge again until I reboot it... disconnecting the plug before cranking the engine and then whacking it in straight after works around the problem though.
There is probably so much of a voltage drop when cranking the engine that the little DC-DC convertor can not keep the charge current up.
There's something very odd about smartphones these days. If you supply them with +5v and ground through the USB port, they won't charge because they want a 'signal' from the thing doing the charging. The point of this is to make sure it does not draw more amperage than the charging device may be able to provide. However, most EVERY way of charging can supply well over an amp. The only thing that CAN'T are AA battery-powered chargers. However, those aren't even in circulation for the HD2 AFAIK.
Does anyone know of any fixes/files to mess with/basic solutions so that and HD2 will charge from +5v? My phone won't even charge from my computer. It's really obnoxious, and I just bought this solar powered charger....
EDIT: !!!IGNORE THIS POST!!! It turns out I had some setting checked "When connected to a PC, do not charge while the phone is on."
Who in the world needs such a setting?!?
I tried googling this but could not find anything. Does anyone know the power needed to keep the Turbo 2 from having the battery drained when running with the screen on full time?
With my Turbo 1 I was using an older Blackberry wall plug in my Jeep's power outlet and that was good enough to keep the phone at the same battery level while running Waze(as in, no battery drain, but also not charging).
With the Turbo 2 it is slowly draining using the same wall power supply.
I was wondering if anyone knew the minimum power I would need to keep the screen up 100% of the time, like when running Waze? It can be any form of power supply since I have a plug in outlet in the Jeep, as well as cigarette outlets and USB.
I could easily use the charger that came with it, but it pulls 25w which is a little much and can cause car battery issues over the long run, which I am trying to prevent.
I use charger for cigarette outlet with 1 A output. If screen is off, charges phone. If is on, keeps on the same level or charges slowly. Real amperage depends of the usage, screen brightness, etc. Of course, you can always use ammeter and measure exact current in the specific condition.
You can Buy the motorola turbo charger for car. I bought the moto X Force here in Best Buy México, and it came for free. Maybe it can solve your problem.
