Hi everyone,
I have just swapped my Galaxy S3 to a HTC One X+ because I couldn't stand Samsung's Touchwiz, and I love Sense 5. The downside is the charging times on this new phone are pretty laughable!
Now I know different cables can give different currents consistently, but I have three cables (one at work, one in car, one at home) that would all deliver 1000mA to my GS3 and I could go from 10% to 100% in about 90 minutes, about 1% per minute, it was great! Battery life on this phone never degraded so I know 1000mA wasn't damaging at all (all GS3s can take a maximum of 1A).
I've now moved over to the HOX+ and it's taking absolutely forever to charge, between 3-4 hours to charge from low. I simply can't wait this long, it's beyond a joke :crying: I've checked Better Battery Stats and my battery usage is about the same as my GS3 when unplugged (about 4-5% per hour) which is fine, so why the difference in charging times?
On my GS3 I had an app which showed me charging current that was specific to GS3s and was very reliable, but I can't seem to find a reliable app for the HOX+, the one I have is Battery Monitor Widget and it reckons I'm charging @ 330mA and I'm currently at 22%, that can't be right can it?
Here is what my phone is says when charging "Charging (USB)".
In the past hour it's done about 20%.

Erm thats the issue. When you charge using the AC (By cable to the electric socket) it says "Charging(AC)" . This usually takes me from 10-100% in about 90 minutes with the HOX+.
Somehow either you are connecting it to a usb hub (laptop or a computer) which is pretty slow compared to the AC, or your phone is mixing up the AC and USB currents. So an advice, use an electric socket and make sure it says "AC" in the power tab. IF so, check the charging time you should find it similar to that of Samsung.
I also think usb 3.0 is faster in charging than 2.0 ? If you are on a new pc with a new motherboard you should find your sockets 3.0, so don't use a usb hub especially if it says usb 2.0 since it will be pretty slow.
Hi Gand0ur, thanks for the advice.
I should have said before; I never charge via a computer/laptop/USB hub. Only directly into the wall. It is an aftermarket charger but it's a good quality one as it charged my GS3 @ 1A and also my old Sensation charged in about 90 mins.
I've just tried a different cable and still the same outcome. I'll try another wall plug when I get home tonight

Sorry.. I am kinda sleepy so I posted without saying any thing. Anyway I wanted to post a pic of the text on ny stock charger. Says the following : output: 5v ~ 1A .
I will post a picture when I wake up in a couple of hours.

No problem! The charger I am currently using is a 5V/2A (for tablets) and has worked fine for every phone previously, giving 1A current.

That isn't necessarily true. This charger has been the fastest thing to ever charge my HTC Sensation and GS3, and come to think of it my Nexus 7 charges faster with this charger too. As I said earlier, I had an app on the GS3 which showed it was outputting 1000mA (maximum the GS3 allows) and it would charge that phone in around 90 mins. According to the HOX+ app I have I'm only getting 330mA. Whilst I agree that poorer after-market chargers often give dubious results I'm confident that this isn't the charger's fault.
I'll try the a HTC charger when I get home, but the other night I had it on charge with the HTC charger and it didn't seem to move very quickly.
I'll just say what I know from experience with my HOX+: it only seems to be charging in a normal (and pretty fast) way with the original, from the box, charger.
I tried charging it with the charger from a Desire Z - slow; charger from Desire S - slow; a Nokia charger - slow.
I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I think you're right! I tried my wife's HTC One S charger last night (because the HOX+ doesn't come with one) and it changed to Charging (AC) for the first time. I have to say this is a massive let down for me, my car charger saved me so many times with my GS3 (for example I drove to Scotland and used GPS all the way, and the phone still charged right up at the same time) I'm not sure I can handle it not being able to cope with other chargers.
I find this extremely frustrating Is there not a hack to get around this with root?
I'm not sure about the Samsung, but the HTC will only go into the fast/AC Charging mode when it see the Data+ and Date- signals shorted on the USB port. This can be designed into the charger, such as the factory HTC wall charger, or you can buy "charging only" cables and then use any USB charger to get your HTC to go into AC charging mode. These charging only cables are tough to find, but amazon does sell them. Keep in mind that the charging only cables will not transfer data at Data+ and Data- are shorted. Once you are in AC charging mode, the phone takes over and determines how fast to charge. At low battery levels (less than 80% or so), the charging rate can be as high as 1000ma/h or the maximum the charger is rated to deliver. If the charger is rated to deliver more than 1000 ma/hr, the most your phone will draw is 1000 ma/hr.
Now there is another variable, the cable itself. Cheap cables sometimes have too much resistance to pass 1000ma/hr and can be the problem as well.
One other issue is the number of knock off chargers and cables out there. Beware of e_ay. You may not be getting what you think you are.
One final note, Apple designs the ipod to look for the Data+ and Data- signals to not be shorted (opposite of HTC and most android manufacturers). So chargers that are designed to charge Apple devices will need the Charging Only cables to charge android devices in the AC charging mode.
So if I didn't confuse myself, hopefully this will answering some charging questions. I've researched this and have tested many chargers and cables.

So, I don't know if this is just my device or maybe already known. I don't see it here(or google) so I am going to post this so others can find this info faster than the 2hrs it took me.
Some Li-Ion batteries have a low max charge rate. Meaning you cant "over-current"(mA "Milli-Amps" or A "Amps") them too much(saves life). Well my Razr just showed me this. This can allow you to charge the battery faster if you have one that is tolerant of the "over-current".
Apparently maximum for the Droid RAZR is somewhere between 850mA and 1000mA
Tried using an HTC @ 1A and no joy.. wont charge.. actually says charging.. but the battery seems to have flipped the switch to not charge; and just continues to discharge normally; even the hidden status(dial *#*#4636#*#*) says charging but obviously not! Tried different HTC models and different cables. I am now only using my Moto supplied cable.
Even after it was dead. It would show the charging screen @ 0% and the light would be red. Stating that you cant turn it on cause there is not enough juice to finish boot. It would never go Green no matter how long I waited(10-15 minutes) usually only takes 5 minutes.
Found my OG Droid charger; remembering that it was lower than 1A. It actually is 5v 850mA. Charging away!
Remember the stock charger is rate @ 5v 750mA - this means you can probably use chargers from 700ish to maybe 900ish mA. I cannot confirm these estimates. Anyone else seen any other rates work?
Hope this helps someone down the road. I know it would have helped me!
MODS - Please, if this is wrong info please DO NOT HESITATE to notify me/remove/edit my post. I just want the right info somewhere, cause it was not well documented anywhere i searched via google.
Also - Thinking more on the subject - this could be the "Authorized Charger" bull that Moto likes to put on its devices i.e. The RAZR flip-phone was notoriuosly bad about this. Even my old nextel "beep beep" had this problem with OEM chargers. Had to spend $15+ on the official one. Again - if this info is wrong in ANY way please fix it or remove it.
use official 850mA charger and be happy. Motorola also confirmed using 1A chargers without any problems but any ways original ones are recommended.
Brilliant, my problem now makes sense!
Couple of questions: What does this mean to charging via USB instead of mains? Is it the plug or the cable that is rated to a certain ampage?
One more question. I found another usb plug rated to 300mA. I presume using this will just mean the phone charges slower? It won't have any negative effect on the battery?

Just adding my experience... Have been using an iphone wall charger w/ the usb jack on it and the supplied motorola cable. Its listed as 1000Mah. Battery Monitor Widget shows it charging around 945Mah. Doesn't get hot, charges like a bat out of hell. Down side is phone is about 60% unresponsive during the charge.
Found a little info on this. Apparently different cables, when plugged in, short different contacts to let the device know what it's plugged in to. Resistors change the current. Audio out can tell if it's plugged into a dock versus USB versus wall charger. The Verizon replacement didn't work for me, but an hard incredible one did. They both charged but only the htc recognized computer connections

My stock Razr wall charger is 750mA. I use a 1000mA car charger and it works fine - doesn't get hot and charges faster.
But sometimes you do have to be careful. I had a friend who's noob mother fried her Bionic with a charger that was too many mA for it to handle.

strange... my stock charger's rated 850mA.. maybe because i use international GSM version of RAZR.. but it charge just fine..
but even i tried charge it with blackberry's 700 mA charger or my ipod touch 1000mA charger it both charge just fine.. and it feels like the 1000mA charge slightly faster..
too bad i broke my old nokia n900 1200 mA charger..
I'm using an HTC 1A charger: the RAZR doesn't become hot while charging and it's charging faster.
The limit is 1A anyway.

dang! so i guess nokia 1200mA charger won't be any good then..
thanks for the info though.. i was thinking of getting myself a nokia charger after read this thread..
Ever since my first motorola I've noticed that the stock charger is 5.1 volts.
Charging with other brands always seem to give worse battery life.
My old Rizr only lasted a day when charged from the USB of my computer, but 6-7 days with the original part.
Some of that is apparent with my car charger too, it says it's taking charge, but sometimes it will run backwards with GPS running..
I experience the charger issue last night.
I had low battery when I went to sleep, put the cable in and it said charging.
Came late to work because the phone drained the battery instead of charging. I used a 5V 1.2A charger and its been working great until last night. And I noticed my original charger is 5.1V 850mA for the Razr.
You learn something new every day!

Did anyone try to use HOX+ in car as navigation? I have quite strong charger in car made for iPad (2.1A rated USB) and it is not able to charge phone when it is running navigation (Sygic, but it doesnt matter). It seems to me, that charging current is too low to charge battery and also power phone, which is actively used. Tried to repeat at home, again big Apple USB charger from iPad rated 2.1A and while I was actively using phone (browsing etc), charger was able to get 1% of battery charged per 15-20 minutes. Which is too long.
Phone is getting warm or even hot while using CPU actively (Chrome is able to run all 4 cores while rendering page) and maybe there is some protection to avoid HOX+ getting too hot while charging? Or maybe internal logic just doesnt take more juice from charger when phone is charging and being actively used (to power CPU/GPU and also charge battery)? Anyway result is that with intensive CPU/GPU apps like navigation, I cant charge phone fast enough and it is actually discharging! No matter how strong or good your charger is, phone takes constant current and sometimes its just not enoug...
Anyone got similar problems?
The problem is that you shouldn't use chargers meant for other electronic devices.
How is it with the charger supplied with the X+?
Bbattery Monitor Widget is good to track charge/discharge value.
I have not noticed anything out of the ordinary, even using the phone while it is charging.

And what is the difference between chargers with USB ports? I could understand that using cheap noname charger from China could be problem, but I'm using branded from Apple, which is known to be really well made. And it is providing 5V and up to 2.1A of current.
Anyway cant use original because I bought phone in UK and they have some ugly shaped power plugs unlike rest of Europe
...but it ain't working, obviously. A power adapter is like a couple of €s, and @amazon original charger are around 7 €

I've used both an OEM US charger and the UK charger with an adapter with the OEM cable and both have done fine. It does take longer to charge while using it, but that's no surprise.
The Apple charger should do better.
Simply put, the device reduces charge rate if the device gets too warm. I don't know if this is happening but it's something to keep in mind.
I had this issue also when i was using the device. Charging was stuck at 99% and did not change anymore.
Sent from my HTC One X+ using xda app-developers app
Well, you probably can't top the battery while charging because the phone is drawing more current than what the charging circuit (internal to the phone) is able to deliver to the battery (while charging).
Been digging in this problem a little bit more and found strange pattern. Since I cant use original charger (UK version doesnt fit my outlet), I have to charge with Apple ones. I have one big for iPad3 (strong marked as 2.1A), one small one with 1A and one small one chinese copy from DX (also 1A). When I try to charge phone with first two, it just charge like USB (settings>power and there you can see type of chargin on the top of screen). When I use chinese copy, it charges like proper AC adapter, quite fast. But after while, touch screen is messed up and it is almost impossible to control my phone. It seems like some static electricity build up or something like this messing with toucscreen mechanism. It gets fine few seconds after removing phone from charger.
Tried different cables, have 3 types at home. Original cca 1m long, only chinese charger woks in AC mode. Then I have extra short for drive, same behavior like original and two long ones (2m), chinese from DX but well made with quite thick cable and with this even chinese sometimes charge like USB, but sometimes it connects like AC.
Always thought that Apple chargers are good and used them to charge other gadgets, never had any similar problems. Seems that One X+ is quite picky with chargers, anyone can verify if it is just my piece?
I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.
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?

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.

There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

I have the charger that came with the phone it it fully charges my DNA in 2 hours from 3%

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.

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.

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

Same here, 2a Nexus 7 brick with a long Logitech USB cable, much faster than stock (and longer)

I'm fortunate my car has a built in inverter that I use for charging my phone.

My next car will too, because I can only imagine that power requirements for these devices is going to increase.
That said, I think I have a winner, and instead of retyping my posts, I'll just link to that thread instead: http://forum.xda-developers.com/showpost.php?p=41797839&postcount=6
Since the snap Dragon 600 has fast charging capabilities, why didn't HTC Include it in the kernel??? I've noticed my 2500 mAh note battery charges faster than my 2300 MAH HTC one
