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

I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.
where to get a charger
i tried 2Amp chargers....didn't help/
my brother says:
"the pins are slightly different/off/longer/shorter/what DID lenovo do here?"
as a safety i bought:
http://www.ebay.com/sch/?_kw=886605022780&_clu=2&_fcid=100&_fvi=1&_localstpos=&_stpos=&gbr=1
just in case...
it costs an arm and a leg for a microUSB charger, but not charging the device for a couple of days would cost me more :S
just another things that makes the TPT slightly less then perfect

Charger
I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.
http://rootzwiki.com/topic/8523-rev...arger/page__st__40__gopid__448194#entry448194
In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
So my charger met with an untimely demise. I am unable to get my hands on a replacement one at the moment.
I am currently using my computer's USB port which as you will know doesn't give quite enough juice. I have seen a microusb charger with 5V and 2A. Will this do a job (and also not get rid of the message that i am drawing more juice than the battery is getting)?
I use the charger that came with my Evo 4g. It needs to sit overnight, but it charges to green.

No.
The reason for the strange shape USB lead HTC have is that it gives 9V and 1.7A - 5V isn't going to cut it, it will charge but ever so slowly and if you try to charge whilst using it you'll probably find it doesn't, it just discharges more slowly.
If I were to take an old wall wart I have here that is 9V and 2A and wire a standard micro USB cable to it, would that work to charge my flyer quickly? In other words is the strange connector necessary or just the 9V and 2A?

NO, because the fast charge requires the special connector on the HTC power cord , a micro-usb will not allow the Flyer to draw the high current.

If you're using the HTC-specific microUSB cable, the adaptor would have to provide the correct amount of power (9V and 1.7A). Most usb power adaptors do not provide the adequate amount. A little while back, I made the mistake of taking just my phone usb adaptor to charge everything on a trip out of the country for nearly two months. It worked great for everything except for my View. Even though I had the HTC-specific usb cable for the View, it was still like charging via a computer usb port. It would get the job done if I left it all day or all night, but it took forever to charge.
I really would try to track down an OEM charger. Even if you find a usb adaptor that puts out the right amount of power, it still might not provide the short amount of charging time that the OEM charger does. It should theoretically, but many users have had charging time woes when using anything but the OEM charger.

Volts and Amps - PowerFlask
From the posts on this subject it seems that the Powerflask 13000 mAh powerbank I bought today and which charges at 5.3 volt with a 1amp and 2.5 amp port won't properly charge my flyer?
Can I safely use the 2.5amp port or should I rather stick to the 1amp port.
Any advice would be much appreciated.
Thanks

Folks on here have mentioned that the device (and other tablet/smartphone devices) will only draw the amount of current (amps) it needs. So using a charger with a higher amp rating is not a concern (in theory).
But I think others have debated this, and even made claims of higher volt/amp rated chargers damaging their devices (however anecdotal).
In any case, from the responses on this thread, it appears that any charger that doesn't have HTC's proprietary connector that they used for the Flyer, will charge the tablet very slowly. I just plugged my Flyer into a microUSB charger the other day (just got back from a trip, and my stock charger was still packed), and it charged extremely slowly. It was slower than I remembered it being. It was plugged in for maybe 4 hours, and only increased the charge by 10 or 15%.
PowerFlask Volts and Amps
Thanks for the feedback, much appreciated.
I ran a quick test and connected the Flyer to the battery pack.
The flyer charged from 76% to 84% in 30 minutes . I realise that such a short charge isn't a proper test but it looks promising.
I used the 1amp port and will as you cautioned avoid the 2.5 amp port.

None of my micro USB cables will charge my E970 without a "slow charging" notification except for the cable that came with the phone. Even the venerable 6' monoprice cable isn't up to the task. HTC cords aren't cutting it, either. Does anybody have any 6'+ (ideally a 10') micro B cables that will charge the phone without slow charging? My monoprice 6' cables (i have a bunch) barely keep the phone from losing charge when serving up LTE hotspot, where as the LG cable charges it whilst doing whatever I can to suck down as much current as possible.
Also, I really don't want to short data cables. Somehow the stock LG cable does full current while maintaining data capability, and that's what I'm looking for.

OEM LG cables can be found almost anywhere used so that shouldn't be a problem. Otherwise, you may be looking at the wrong end of the cable. I have a spare tablet plug charger that puts out up to 2 amps and that seems to be what works best for me no matter what the cable. You might want to look for one of those instead of just buying more cables.
FWIW....I had the opposite result. The cable and adapter which has been near my bedside for the last year (for my HTC EVO 4G) kept giving me the slow charging notification on my me LGOG. If I used the LG adapter and cable all was well, but it was shorter than I wanted. I changed out the adapter and kept the older long cable and still got the slow charging notification. It seems most of my existing cables have this issue...even when using the new LG adapter.
I have not looked into power capacities on the usb cables since I charge each night and don't need to recharge during the day. Didn't expect there to be a throughput difference, but the new LG cable does seem to be different.

What is the part number for the oem charger and USB cable?
I use a Samsung charging cable with my LG plug and it charges regularly. I love the Samsung cable because the mirco-usb plug is asymmetric so I always plug it in correctly the first time, every time. Even in the dark. The cable is pretty long too. I don't use the Samsung plug because it only outputs 0.7A though.

Same problem here, just started about a week ago. It doesn't matter what cable I use it keeps switching between slow charge and regular charge.It charges without problems when the phone is off though. Also when I plug my phone into my pc it keeps disconnecting every few minutes. I'm starting to think its a problem with the phone itself and not the charger or cord as they work fine with all my other devices just not the Optimus G

I use all sorts of cables and so far the only time I see "Slow charging" is when it's plugged into my laptop or one of my USB hub. Those are the only times I could narrow mine down to.
In the car I use cheapo monoprice cable and charger, in the bedroom it's using the charger and cable from my HTC inspire. By my PC I have a Belkin 6 plug 2 usb wall charger installed with the stock cable, and at the office an iPhone 1G wall plug. I don't think I have even plugged in the oem charger that came with it.
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?

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

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.

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.

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.

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.
