I am not sure if it is a coincidence, but after I updated the tablet to 9.4.2.21, it will not charge. I can plug it into my laptop, and it is recognized as a ADB device, and ADB pops up on the tablet, but it says not charging. If I plug it in to a USB Power jack, it does absolutely nothing. Does anybody have any ideas? I think I may try a system restore, since I never did when I installed ICS.
I have none of the issues that you mentioned. Try a soft reboot, that should help.
I tried that at first, and I just factory reset the tablet, and to no avail. I may have to go back to best buy. Ill try resetting with reset button, an hope for good luck.
[edit]
Dumb thing, the Asus power block outputs a higher DC voltage than a normal USB charger, and the tablet will only charge from the Asus block. Odd because I have used other power blocks previously.

Are you trying to charge from the laptop USB port or from the Asus wall charger?
If you are trying to charge from a PC USB port, you should know that the Prime won't really charge from anything less than 15v which is 3x the voltage supplied by your PCs USB port. Also when charging from a 5v USB source the Prime won't charge at all if it is not turned off.
If you are trying to charge from the Asus wall adapter you might check out this thread:

FWIW I got the .21 update this morning and I have no problem charging my Prime.
i recently had this issue - i have not updated to .21. neither my dock or my tablet would charge for over a day. it ended up fixing itself somehow, the dock battery died but there was a little left on the tablet. just suddenly started charging. my computer also recognized my TP without issue.
try unplugging it for a while, let it sit plugged into your computer for a couple hours then back into the wall...thats what i did at least.

This is probably a charger issue over a prime issue. The charger will shut itself off if it determines it has gotten too hot, sometimes permanently... Try popping the thing in the freezer for a bit if the problem doesn't resolve itself in a few hours.
Same issue here. Just updated and now no charge.

ive not had this issue, mine was at like 20% when i did the update and it charged fine after

It's not supposed to charge on anything less than 12v, which is what the official wall charger outputs. My Prime's never charged over PC USB (5v), even before the .21 update.
The Volts and the Amps are important...

The prime will charge from a 5V USB socket; albeit slower than from the supplied 12V unit (and it helps a lot if the Prime is off at the time.)
The other factor is the Amps that the USB socket is able to supply. A "good" mains powered 5V USB socket will usually be able to deliver 500mA - 1000mA which will charge a modern phone at a fast rate.
A PC USB socket will probably only be able to deliver fewer amps; which is why phones charge slower from a PC USB and may not be enough to charge the Prime at all.
I have a 5V USB wall socket that's able to deliver up to 2000mA and it is able to charge my Prime.
- And just to add, my Prime has been charging fine since the .21 update, and generally running better all round...
Mine charged fine overnight.

Ah, true, it is written in the tiniest writing on the adapter. I just checked the manual and it states the TPF requires 15v at 1.2A for charging. Not sure where I got the 12v from.
One more thing: I've realised that if charging from 5V USB with the TPF still on, the TPF doesn't show that it's charging, even though it is, slowly. This could explain why some people are reporting that it won't charge from USB.
Fixed it by plugging into PC then back into charger. Weird that it quit charging first time plugging iafter update.n

My prime stopped charging for the 1st time. Don't know if it's related to the .21 update...tried reboot etc didn't work.
In the end it started charging again after I followed others' experience that unplug the charger, connect the tablet to pc via the usb to verify the cable connection, wait 10-15 min (the theory is that the charger would reset itself this way which may have turned itself off after being perhaps too hot from previous charge, I didn't put the charger in the freeze as others suggested because it's cold already), plug it back in and it started charging again!
Never had this issue before the .21 update, could be coincidence. Was really worried earlier as my battery was at 2%...

Is there a difference between a charging cord for the EVO and a standard USB data cable for our phones? I thought I remember reading a thread about the charging cable being different so charging faster.
The reason I ask is I need a 15ft USB charging cable for my EVO.
It's all based on the power drawing from the source. I don't think the cable makes a difference.
As a general rule, USB charges slower than AC.
I can tell that there is a difference!
I used normal USB cable from my other mobilephone (xperia x8, and Nokia 5230) and my HTC Evo 3D didnt recharging, he was showing that he is recharging but no... recharg was so slow that he wasnt able to recharg battery. After couple of hours from 20% it went to 18% of battery

I understand that trying to charge off the computer will be slower. But what I was asking is the cord which you plug in to the USB wall adapter (that comes with the phone) different from your average micro-usb cord. Because at the end of the day, the cord we get from the factory to charge is a micro-usb cord.
But I think I read somewhere that there is a difference in the pins or something that identify as a charging cable instead of a data cable allowing more power to pass through.
Not sure but my knowledge tells me that when u plug USB cable to poweradapter it just becomes regular charger and phone knows this by higher voltage coming to it...while USB plugged in to laptop or computer less voltage tells the phone and as well as the drivers from computer tells phone that's its USB cable link! Essentially cable is same but the.power adapter in front just converts USB to 2-pin regular power source!

I just did an experiment with my charger. I used the stock HTC charger that came with the phone. Plugged in my HTC provided cable, went to battery status, and it said "Charging (AC)".
I then tried another micro-USB cord I had laying around and again it said "Charging (AC)".
So my guess is the cord doesn't matter. What I'd like to see is if there is a difference in power that the cord is allowing to be pulled between the two. Anyone know an app for this?
Next I went and took the Griffin charger I bought for my iPad2. It is rated up to 2.1amps for output so it should be sufficient enough to charge our phones just like the stock charger. When I plugged it in using the stock HTC cable and the standard Micro-USB cable, both read: "Charging (USB)". Again, I wonder if there is a difference in power being drawn because it thinks it is USB.
The cord probably doesn't matter as long as it's a decent cord. I'm sure there's some POS cords that are not going to deliver much at all, but any USB cable I've bought from monoprice has charged just fine, and has done its full output either via a usb port or if I plug that cable into a usb->AC adapter.

Elixer 2! Grab it from the market, select 'status bar' and set it up with battery current, which will then allow you to see your current drain (or charge) rate by pulling down your menu!
(lots of other great things in elixer! I urge everyone to check it out! It's totally replaced extended controls for me! Probably the best utility in android since TB!)

The phone sets the charging rate based on if the data lines of the USB cable are active. If they are active, the charging rate is limited to the standard 500mA USB supply. If open, the phone goes into AC mode which allows up to 2A (2000mA) charging rate depending on the power supply.
I'm not entirely sure if MicroUSB is different than some of the other standards out there. But there are indeed some usb cables that are ''Data'' cables and do not charge. I have an old flip phone for my son and his usb data cable connects to the pc fine, we can transfer music to his microsd card etc. However it does not charge his phone at all.
I've used a couple of different cables and here's what I've noticed...
Some cables won't charge, but can be used for data.
Some will charge, but can't be used for data.
Some can charge, and be used for data.
I know that some that charge, but can't transmit data have the data wires missing for cheaper production. And this could be the same thing for those that can be used for data, but not charge.
Sent from my PG86100 using XDA Premium App
Can also change data cables into AC charging cables only, so that they will charge at 1000mA from a USB port and not 500 mA as normal. Means you can't use the cable as a data cable, but in a car charger that's not a problem, and often you want a quick charge from a USB port.
Basically the two data pins have to be shorted together--google it.
EDIT: See here-- http://pinouts.ru/Slots/USB_pinout.shtml -- basically the white and green wires need to be shorted together. I have done this and my phone now says Charging (AC) when using car charger or USB from PC.
basically you can have three types of usb port/cable as per 2007 Battery Charging Specification - regular data cable ("old" usb standard) that cand provide up to 100mA without negotiating with the hub, 500mA after negotiating; charging downstream ports that can provide up to 900mA plus data without needing to negotiate; dedicated charging ports that can provide up to 1.5a without data (Ive seen 2a chargers so I suppose this is covered too, in the official standard I cant find it)
Ir does matter. The original usb cable must have some extra or different pins, because when I use a generic one I'm not able to adb to the phone from the PC, I'm only able to adb with the original usb cable. Charging is fine.

not sure if this is good for the battery to leave it plugged into the charger when it's at 100%..
i been told before that these new devices it's ok to leave it plugged in...but i don't have a good feeling about this lol
it'd be great if someone can please chime in on this.
thanks all!
Yes it is OK. The charging circuitry will switch to a trickle charger when battery is almost fully charged.

Just keep your batteries with more than 20-30% charge as much as possible.
Sent from my GT-I9300 using xda app-developers app
I leave my phone charged to 100% almost all the time:
- when I am at work I leave it plugged to the USB port
- when I am working at home, the phone is connected to the USB port
- when I am driving the phone is connected to the vehicular charger
- when I go to bed, if the phone is below 70%, I leave it plugged on the wall charger overnight.
Yet, when I am on long bike rides and the 3G+ data + GPS + synch are enabled, I still get excellent battery times.
Over charging any battery isn't very good for it, it's the same with laptops and well pretty much anything, so long as power is coming in the battery will take it, even if it is at a slower rate.
Ideally you would want it to charge to 100% and then a little bit more, maybe 20 mins, to make sure.
However i know we don't live in an ideal world and charging it overnight is the only thing that can be done by most users.
In my work we have a lot of phones plugged in all the time (all brands) and they have some strange effects happening, eg: Unresponsive touchscreen (removing the charger solves this), Poor battery life, glitchy screen etc.
Saying that, all of our phones are plugged in all of the time so it is an extreme situation.
If your worried about it then get a timed plug so it only charges for a few hours and then cuts off.
But you should be fine otherwise.
Just feel the charger when the phone's at 100% and it's giving off a f**k load of heat because the phone isn't actually taking anymore charge and the charger turns the reduced MAH it draws into heat in the charger, so just don't worry about it because the phone does all the work for you and can't go over a full charge.
My phone stops charging at 100%.

Yeah you can use any Micro USB cable or charger as long as it outputs no more than 1000mah.
I thought a higher output was "good" in that it reduces the charging time.
Could you please explain why one must take into account a limit?
Conversely, is a low output harmful: how about charging from a laptop USB port?
Also, I have a HTC One X. Can I use the Samsung charger with it: how do I find out the output limit for the One X?

A higher current can damage the battery and possibly the phone and some people say the phone at any current above 1500mah but still haven't seen any proof yet, and you can probably get away with 1300mah but the more you the the hotter the battery gets then slowly expands and might pop, and yes you can use the HTC charger no problem but check any charger you use for output current wrote on charger, and also yes you can charge from a laptop or any really slow charger you like.

Correct me if I am wrong, but I thought the Samsung phones block excessive current and can accept up to 1amp. Also when using any charger that doesn't have the middle cables short-circuited would produce 500milliamps regardless of charger's output(this can be turned off with custom kernel). That's why there is a list of car chargers on gsII or Note forums that have the pins shorted. That said, people had reported that using HP touchpad cuts down in charging time while increasing heat.
I am looking into this a little more and some useful info I found.
My GT-I9300 charger outputs 1000mA @ 5V. The phone charges up quickly. No problem there.
When using a USB port on my Macbook Air (2012 model), under About This Mac > More Info... > System Report... > Hardware > USB > bottom USB High-Speed Bus Hub listed: I see that 500mA are avail from the USB 2.0 port (conforming with USB 2.0 standard specs), but the GT-I9300 is only requesting/ drawing 96mA, whether I am using the original Samsung USB cable which came with the phone or my favorite short Jawbone ERA USB to microUSB shorter cable.

It just takes much longer to charge.
My One X (S720E) draws the full 500mA avail from the port:
It should be noted that some Apple peripherals/ devices (iPhone, iPad etc.) can request and get an additional 500mA from the port on computers/ monitors that supports this.
Here is the Apple Support Article that covers this.
Pretty much everything uses Lithium-Ion these days, and it's perfectly safe to leave overnight, heck I even upped the AC charge voltage to a straight-up 1200 on AC power.
Charging at lower powers is equally harmless, but if you use the phone you may drain faster than it can charge.
All in all, thse rumors about decreasing battery life are getting sillier and sillier these days. Earlier batteries were a bit finicky, but they have improved A LOT, and honestly, a new samsung battery costs 25 dollars? If I'm still using this device in 3-4 years when the battery finally gives out I'll be very surprised.

Read through al the other charging issues posted and can't find one like mine. So here is my issue.
Prime been working wonderfully then yesterday was on it watching netflix videos and while plugged in it kept loosing charge until it was down to 5% on tablet and 0% on dock. So I shut it down and left it plugged in all day. The battery icon showed the lightning on it stating it was charging but after sitting for about 4 hours nothing. still showed about 6% charge on the tablet and 0% on the dock. So I tried another outlet and eventually left it plugged in all night well this morning still only about 15% charge on the tablet and 0% on the dock.
Going to try again and leave it turned off all day and see if it charges, will report back in 3 hours on my lunch break to see if anything changes. The prime recognizes when the charger is plugged in and when I unplug it I get the message that it is low on battery. Here's a screen shot of it stating it is charging.
Also note: Neither light on the power button or on the dock is on while plugged up but yet it shows charging on the lock screen.
Edit: plugged in directly to tablet to wall and only has gone up to 8% charged. Seems something wrong somewhere. Tested charger on SGS and it works, hopefully just the cable gone bad. Will order new one to see if that works, but until then no prime for me. :crying:

Update: Have had prime plugged into wall completely turned off. Still no light on the dock plug in or on the tablet itself and now after 6 hours it is only 7% charge. This is pissing me off.
If you have a test device try to check the delivered voltage from charger, if it's correct it' s a hardware **** in Prime, or a bad connector in cable.

The Prime charger delivers 5v when another non-Transformer device is connected. Otherwise they could not use an USB standard connector for the charger
Found out issue. It was my power brick. It is not bad it is just doing a trickle charge to the prime for some reason. Here's how I figured it out.
Did some research and found out that the following charger and adapter does work on the Prime to charge it (Using it now) with the OEM USB Cable.
Radioshack:
Enercell 12VDC*1.5A AC to DC Power Adapter Part #273-358
Enercell Adaptaplug USB_A Socket Part # 273-227
Total Cost $24 bucks and the first adataplug is free.
Is there a fix or work around to the slow charging issue? If I use the stock charger and cable that came with the DNA I am fine, but my OEM Thunderbolt charger (which looks the same) and my car charger I got from Amazon (which I understand may be a knock off but had worked before on the DNA) or any other charger give me a slow charging notification.
This is a pretty big deal for me since I use my phone a lot for work. If I am in the car my phone is not charging fast enough to keep up with drain from the navigation.
I am rooted, s-off, twrp, and running Viper ROM 1.2.0. I understand HTC implemented this "feature" with the latest update. I couldn't find any info about a fix so are people just dealing with it?

You can flash a kernel like crpalmers or zarboz's kernels with fast charging implemented. But what I recommend is buying a USB charger that wont have that issue.
Take your phone somewhere that they have a Nexus 7 or Asus tablet set up on display with the regular charger hooked up.
They sell the chargers lots of places, the Nexus 7 will be best both spec wise and it comes with a pretty nice micros USB cable but I see the transformer prime charger in more places to walk in and purchase retail brick and mortar.They're solid chargers that will deliver the power your phone will allow. You just have to be careful when using it when charging with fast charging enabled it gets warm because it's running that current through their. The OEM charger only runs about 70% of the rated current through there.
Best Buy has a RocketFish 12volt car charger micro USB with an extra USB slot for a second USB cable and device. I almost never use car chargers but I was actually impressed with the quality of this charger. Also HotTips makes a charger that's rated at 5.0 amps and I believe as long as it's not a cheap crumby USB cable it will work fine. A lot of times it's the cable itself not the charger, so I would try taking your USB cable from home to work and plugging it up to that same USB charging plug and see if you get the same slow charging icon.
Thanks for the thorough response. I tried to do some testing combining different cables and charges and the only one that consistently gives me slow charging is the car charger (which worked fine previously). I have a Transformer Prime charger and Droid Razr charger that both worked fine. My Thunderbolt charger worked when I tried this time but has given me the slow charging notification in the past.
I may have to pick up one of the car chargers you mentioned because that is the most important. My phone is running great otherwise with Viper ROM and the kernel that comes with it so I'd rather not change it.

You can flash a kernel like crpalmers or zarboz's kernels with fast charging implemented. But what I recommend is buying a USB charger that wont have that issue.

I believe that forces fast charge when connected to a computer via usb. Some people have said it may fry your usb port but I don't know how true that is.
Android phones in general charge slower when connected via car charger.
this Motorola one here works fine:

or you could always get a power inverter and then use whatever cable you want.
Get the Verizon car charger. Works fine for me..

I ordered these cables from Amazon, got them today and I'm still getting slow charging from the car charger. These are really high quality and still not working. This is pretty ridiculous, HTC should have at least made this optional.
I posted on this a while back, its the cable that causes the issue. If you open up the cable and short the data wires it works perfect. All you needs is wire strippers, electrical tape and shrink tubing.

Thanks for the suggestion. The cables I bought are very high quality, charging specific cables, and I'm still getting slow charging in the car. If HTC only wants to support official OEM chargers that's fine, but then they need to make an official car charger!!
Also, why does HTC only support using the OEM charger when the DNA supports Qi charging? Doesn't make "Sense"

I tried that with the Rezound awhile back and afterwards it still registered as 'charging USB'(aka slow charging).
P.S. that Motorola charger I mentioned above, I opened one up before and noticed it just had the 2 power cables(black & white) and they were also much thicker then the standard cables w/ all 4 wires.
When I did my cable hacks I cut the cable in half, put a piece of shrink tubing on one end reconnected the power wires, shorted the data wires on both plugs. When you do this you cannot reconnect the data wires. They must be separated. I'll post some pics in a few to show you what I mean.

Basically this is what you want it to look like...connect the positive and negative, you can reconnect the shielding too. Also I highly recommend soldering the wires together. Adds strength.

You can do the cable hack shown in the post above as some non OEM chargers do not have the data wires shorted at the charger itself. You can either hack the cables, or if you need the cable for data, then modify your charger. Please make sure your charger is rated at least 800mA. Any charger rated 800mA or below will charge slow. Computer usb ports are rated 500mA and this is why it charges slow. My car's radio has a usb hook up and it also charges my phone at 500mA which is not enough if I'm calling, navigating, etc. The OEM charger is rated 1A. You can use a 2A charger as well but don't use it everyday. Higher rated chargers do charge the battery quicker, but at the expense of the long term battery life.

In my testing even shorting the chargers data pins on chargers seems to be more of a miss. I've done a few and even after shorting them they still state USB mode. It mainly stems from the data pins being present in the cable itself. Two of the chargers I shorted were for a vehicle and they were rated for 2.0 amps. Also if just charging the phone yes don't use high output chargers. But if charging in the car high output won't hurt if you are using navigation, music etc...it actually needs the higher output to charge hence needing to charge at the AC rate.

I have this issue as well now, I never had it till the update back in Feb. I used other Android phones on my car charger and they charge just fine and it only happens with my DNA. I think there is a firmware issue that is causing this to happen.
This afternoon I hacked a cable as shown above, to use with my car charger. I'm glad to report it worked like a champ and my phone went from slow car charging to very rapid charging.
Thanks for the tip.

Hi!
I noticed my phone takes a long time to charge and some times when using it while charging I will get a message about the phone being discharging as the power supplied was not enough or something along those lines.
I downloaded the battery status widget and noticed that at best, the charger goes to about 850 but for that I have to keep moving it as it seems some where inside the ac adapter and the USA adapter plug connected to it, something is going wrong.
I tried the original Sony usb cable and a different one as well.
Either way, when I move the AC Adapter parts connected to the wall, the charge changes and go crazy on the Batter Status widget , sometimes even shows like not even plugged any more :/
So I thought about trying my Transformer prime charger or I can try ordering another one that you guys may recommend.
Thanks!
Here is a pic of the specs on that adapter.
Or maybe I can use a Samsung one like this?
Samsung Charger 2A
Although the above seems to be a fake...so maybe just go with a sony one?
Sony

Looks like your Asus charger is 1.2A (1200mAh), so it's not the beefiest one out there. I'm not sure what the Sony one is, but i think it's 1.5A. Mine outputs around 800 - 1300mAh on the magnetic charger, and it uses around 2 hours to charge it from 0-100%. I usually charge it when i go to bed, but i'm always using it when it's charging in the dock, like wathcing YouTube videos and TV shows. I have never gotten a notification that says it's being discharged while i charge.
Does it get hot when it charges? (spoiler: it shouldn't do that)
I would buy a new - genuine, Sony charger. The thing is, if you buy or use a different charger and your battery goes to ****s, you can wave goodbye to your warranty. Also, since the battery isn't replacable you should treat it like your own son.
But let me summon @hamdogg for you. He knows a lot more about batteries than i do. I guess he'll show up in a minute or 12 hours. Hard to tell But he's on his way.

hahahahah, you see that Asus charger confuses me because it says but then below it also says Output 5V=2A or 15V=1.2 I dont want to fry my phone!
So you get from 800 to 1300 using the Dk30?
Also, what is the model of your Sony charger. I want to try finding one with USA plug already so maybe that Sony one is the best option for me even though I would like to start going with Magnetic charger myself OR charging an external battery (if I get one) to avoid using the USB port too much.
I got the DK30 bundled with the phone. The charger model is EP880 and it outputs 1500mAh. It only says Sony on the dock itself.

Got ya. Well I decided to get the DK30 even though now I am having second thoughts since some user seems to be having luck just using the magnetic adapters and connecting any usb cable to that adapter instead..but oh well, I guess I will get the DK30 and see how it works out for me.
Still trying to decide on that 4500mAh case/battery too!

Sorry have been away for a few days...
amps are fine no matter what the range. So 1.5 right up to 4.0 amps will not damage your device.
Volts on the other hand can damage your device. Don't go above 6v.
You should be able to get 5.v and 2.0 amps out of a wall charger, if not then its not been made properly, or not efficiently
[I have a 2.1amp unit and it suits me fine]
The difference is that your device will pull what ever I can up to a maximum, It look like the ultra can only pull 2200 (give or take) out of a charging unit, so any wall charger that states its over 2.5 amps will be a waste.
-So don't pay extra for anything above 2.2amps thinking you'll get faster charging. You wont.

I got a free 5000mhz solar charger unit sent to me to review. I'll make a video for my channel shortly about this unit. Think it retails for $15 USD. Look pretty good, just need to test it on my ultra in a few days.
The thing with battery packs, is that it needs to be 200% larger than the internal battery. So if your Ultra battery is flat, then it charges off the 5000mhz battery pack, that would mean to it wont fully charge the ultra. It will get to 2500mha, and the battery pack will get down to 2500mhz, and then it wont be able to transfer charge. (Unless you can give charge to pack)
So my solar pack can charge my device to 75%, and then continue to charge it while the solar panel charges the pack..
Does that make sense??
There we go
