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

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
thanks in advance

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....
I use the 2m cable that came with my kindle 3 and it works as well as the original one

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

Double the length, double the resistance of the wire. Assuming the have the same cross-sectional area.
i was shopping for a oem Car dock that would work with our phones but also fit any case i wanted to put in the dock so heres the solution im ordering mine this week
http://www.amazon.com/iBolt-Vehicle-Car-Mount-Dock/dp/B008B0WNA6
Did you get it? How did it work out?

I've seen this one on amazon, Kidigi usually makes good quality stuff and - as it looks - comes with the insert as well so it could be used w and w/o case
http://www.amazon.com/Car-Charger-M...2&keywords=kidigi+charging+car+dock+htc+one+x
...comparison with the price of the iBolt ...looks like the same device to me.
I've had the iBolt car dock for a few days now, and it's working fine. It's a little clunky compared to my old Atrix car dock. I don't have a case on my phone, and the clamp on the top seems to sit on top more than grab it, but the phone is snug in there.

Have you had any charging issues with yours?
When it goes into car mode and navigation is on, it barely charges if at all.
I spoke with iBolt and they are sending me a new one. Hopefully this resolves the issue.
I am still curious if anyone else is having this issue.

The issue isn't the charger but the USB cable not being shorted to put phone into AC charging. Pins 4&5 need to be shorted to allow this to happen. I ordered two of these http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o03_s00_i00
to go along with this http://www.amazon.com/gp/product/B008B2EFA0/ref=oh_details_o05_s00_i00
and has allowed me to use the HOX+ for hours of navigation and still charge the phone.
For car dock I use this: http://www.slipgripcarmounts.com/SlipGrip-Vent-Holder-For-HTC-ONE-X-S720E-Using-Seidio-Surface-Case_p_130568.html
I agree that the ibolt is a little clunky but i love it. Its really sturdy. It stays in the position you locked it down at. It's easy to dock the phone with 1 hand. I havent noticed any charging issues but i'll keep an eye on that now that you mentioned it.
interesting
and to think i was going to try and mod my Atrix toys to see if i could make them work.. .this looks way easier, wonder why they dont include the proper cable in the first place or if there are any other docks similar

Hello,
Well it's been quite some time but I didn't wanna open a new thread for this.
I'm using the iBolt dock for my HOX for quite some time and as told above it charges really really slow.
You might say it is caused by the cable, makes sense, but the charger I use to connect the iBolt is the geniune HTC car charger, which does charge the phone pretty fast.
Also, I exit car mode when I don't need it and turn the screen off in order to charge more, but it randomly and frequently turns the phone on. Sometimes just the Android homescreen but sometimes it re-launches the car app too. I was planning to call iBolt for this but I do not have much hope for getting detailed information about the output (actually the USB pin design) since there is no information about this on the web sites.
Can anyone confirm that it supports fast (normal) charging? It becomes useless beacuse of this issue.
You can easily check for yourself. While the phone is docked in-car, do the following: Settings>Power>verify that phone reports "Charging, (AC). If phone does not say this then you are in-fact charging at 500mA. The i-dock/HTC Charger must be capable of providing enough current to charge at 1A and phone must state it's in AC charging. If this is not the case, your phone will discharge while being used in-car.
I had the same issue of non-charging when I first got my phone in December. My research led me to the solution I previously posted. I do not use car-mode since the only app I use while driving is Waze. I hope this helps.

Late thanks =)
After writing that message it came to me too and checked it, though it was saying that it is AC charging but I can swear to anything, whether car mode or screen is on, or not, it is not charged in 1000mA mode.. When I directly charged it with the genuine charger, it was fine.
So bought a 2amp car charger, and used its cable, and it works fine now.
May be, the genuine HTC charger CABLE and the iBolt are not quite friendly with each other. I remember Nokia's not launching PC Suite when it was not a genuine Nokia cable, may be a trick like that. iBolt does not like genuine cables or genuine cable does not like oem "sockets"
Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?
It seems to do it on any charger or 12volt car to USB adapter capable of outputting 2 to 2.1 amps

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?
Sent from my HTC6435LVW using Xparent Red Tapatalk 2
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.

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.

so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

Cool, thanks man, I'm gonna do that.
Why blow data when you can just get a cheap 4$ cable from newegg with 22 awg power leads. I linked it in confirmed usb cable thread. You destroyed a cable and made it special, hence using a special one instead of standard. The base is pre shorted. You increased AWG technically. Get it? You made a charge only cable, when these are special and can be had cheap anywhere. Buy a nice 4$ standard one with the right power lead awg and you can use it for anything.
...or.. Crazy idea here. Get an Android charger?
Cutting up USB cables is a bad idea, especially shorting them out. The data pins are not supposed to be shorted, generally 200Ohms is expected.
They are suppose to be shorted with fast charge... the base normally does this on plug in on AC switch. A USB3 port also does this... all he did was make a charge only cable. With fast charge 2 though, you won't make it much past 1A this way, just like USB3. Why our stock cable has thick power lead AWG and the phone can reach 1.8A.

As I said, 200ohm, not shorted... Anyway.
unless the plugg that u connect the USB cable in i sent chortcircut it won't fast charge whatever cable u use. this is for making a charge cable to use with carcharger ore power packs. of u use a wallcharger it's 99% certain it is already chotend and u don't need this. but if u use the original cable (fastcharge) it won't fast charge in a power pack or car charger.
and I charge att same speed with this cable then original charger cable that came with the phone. measured 1.8a with this cable that's all my Powerpack can output. can probably go higher depending on how mutch the phone can use.
it's li-po so should be able to charge 0-100% in 20min but whill shorten battery life and don't think oer phones can handle it
I fast charge with 3 different cables. Again, it's the AWG. Facts don't lie. My power pack and car charger are pre shorted, so all good. If not pre shorted though, you are correct sir.
my wasn't that's why I made this. so no matter what cable used it won't fast charge. Som people also say u have to by a expensive cable with is bull####
if someone can provide a link with a preshortens cable... well then show it. unable to find any
It is legit. I did this with a car USB cable when I had my One X. It would only charge at USB rate (500ma) even though it was a 1A charger. Using navigation the battery would discharge faster than it charged. Tried various cables, and only got it to work by shorting the data pair. After that it charged AC at full 1A.

Several available on Amazon:

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.
-sent from my LG G2 using XDA Premium 4
We aren't saying you are wrong, you are just doing something different. It's not about expensive, its about thickness for the combo usb cable. Just the awg. What your solution does is increase awg. They are called charge only cables (pre-post short). What people were searching for are COMBO cables. You are using/doing something different. Why titles are called "working USB" cables, not charge only. We already knew this. There is bugs. That was apparent in the voltage testing. Something in the kernel isn't playing right at all times. I have seen this on my car charger. With no change in conditions, I can sometimes charge 200mA's higher with a replug.

The included home charger for the G2 is rated at 1.8A -- use anything smaller, and you'll see the pop up warning on the phone that charging will be slow and that you should use the "official" charger.
My guess -- if you can find a car charger that actually will put out as much as the phone wants to draw (e.g., 1.8A), and THEN use your shorted data lines, you'll see fast charging of the G2 in your car.

The 3SIXT micro USB charger I have is rated to 1A not modded, just bog standard. When charging I checked the battery stats and it says AC charging. Now I don't know if it has the data pins pre-shorted, but it managed to boost my battery by 10% in under 20 minutes. The phone was idle, but that's not bad going for a 1A $10 charger.
seems like the moderators did a god job deleting som posts.
just want to say I'm a sorry for my bad manur/attitude/language.
keep the input comming
here is another thread about the topic on another device

not true have tried 3 other chargers 1.2 1.0 and 0.8 all say fastcharge (ac) with my modes cable. as long as it's over 500ma and with a cable with data pins shortend the slow charge warning is removed an the phone thinks it's charging from ac
charging my phone now with a Powerpack with 1a output and it says fastcharge (ac)
if I use the original cable it goes to slowcharging 500ma iv meshurd befor I put on the shrinking tube for isolation
and a car charger can output in theory 5-20a depending on your fuse in the car
the charging current is controlled by kernels in so phone. my old sensation u culd mod with a fastcharge Kernel so it never limited to 500ma always use max.
Samsung even has the ability to do a full charge in 30min but disabled in Kernel.
lg - g2 uses lipo battery's and culd actually be charged in less then 20min but if we do that u have to replace the battery every 6month at the best.
and lipo are extremely sensitive to over charge and the cells have to be charged with precision balans not to explode or swell.
