there have been a few discussions about how hot the prime AC adaptor gets, I just measured a consistent 50c temp on the top of mine. I tried a little experiment with a couple of old Pentium heat sinks that I zip tied on either side. while it still cycles up to around 45c it generally stays around. 40c now.
Honestly, call Asus and have them send you a new one. Mine works just fine and doesn't heat up. Those that are have some form of defect. Even if you can fix it, you shouldn't have to.
Mine heats up about as much as my iPhone charging brick does. Sure it gets hot, but I don't think its an issue.
On my old TF101, the power brick heated up so much that it stopped working. The only way to fix that was put it in the freezer for 45 mins before it would work again.
Mine stays cool all the time. If you're is hitting 50* you could quite justifiably
ask Asus to replace it.

My adapter also gets quite hot when charging..one workaround for me was to switch off the prime and then charge it.. sure its a bit inconvenient, however by doing so, the adapter does not get hot..
Just try this option out and check if it works for you...
cheers
I seems that when the tablet and dock are both depleted the charger cranks up to recharge. If I get it plugged in with only the dock low, but not depleted the charger is cooler.

Is yours 220v? If so, I would expect it to run cooler than 110v. Half the amps for the same wattage.

Just a quick point:
Half the amps yes; but that only accounts for a very small portion of the overall power dissipation in the brick. Primary winding conduction losses will be reduced, with a slightly higher core loss induced in the transformer... maybe this is too small of a point to consider, at least it's some interesting reading material?...

Bottom line is 220v is going to be more efficient than 110 (less heat).

half the amps in but unless the prime itself charges at double the voltage as it does in North America then it will be the same voltage/current leaving the charger.

does it have a transformer? I thought these were switching power supplies/
I leave my charger plugged into the wall pretty much 24/7. I know I should unplug it but rarely remember and it never is what I would consider hot compared to many other chargers, just warm.

Hey guys,
I'm in a very unfortunate but serious situation here.
My X10 outright refuses to charge via the power point ( please see: http://forum.xda-developers.com/showthread.php?t=1054455 ). And, now, I'm using the EWJet ROM with Zdzihu's custom kernel. My battery is at 0% (charging is a pain, really slow - also, I don't think it's calibrated properly), and, since I'm using this kernel, I cannot off-line charge!
So, I'm looking for an alternative how to charge my battery. Would cutting my cable and matching the positive and active wire's to the battery's positive and negative terminal's be sufficient? If so, how long should I keep it there for at least some charge to get my battery up enough to start my device?
Thanks guys,
Regards,
Mayazcherquoi.
I wouldn't rly suggest cutting the wires since the x10 has internal circuitry that protects the battery, the battery itself should have circuitry too if memory serves right. You could do it if you know what your doing but Li-On batteries tend to be explosive if you don't know what you're doing. If you push for this method I'd suggest having a voltmeter close to check the battery and charger voltage before starting.
You could try finding a wireless charge pad compatible for the x10 if repairing the phone isn't possible. Since you mentioned cutting the cable and matching the wire and such I figure you're handy. So why not try replacing the micro usb connector? I mean its already busted anyway.
EDIT: Charge pad like this http://store.androidandme.com/sony-ericsson-xperia-x10-powermat.htm , hopefully you can find something cheaper :S

Thing is, I don't really have the parts :-/ And I kind of need this up and running by tonight I cut the wires from an old Motorola phone charger (unable to determine which is positive and negative) which details at OUTPUT: 5.0V - 550mA, and practising on an old O2 Graphite Lithium Ion battery (to no avail ) which outputs at 3.7V - 1100mAh.
So far, no explosions. Is this okay to practice on?
Thank you.
Use a voltemeter to determine the polarity. The old phone battery circuitry may be refusing to charge since the battery may have dipped below the minimum allowed voltage to prevent any danger. Since you've gone this far I suppose it won't hurt to see if you can get it going, check the polarity first of the charger though.
Explosions only happen at the instant of trying to charge a dead li-ion without circuitry or trickle charge and also in the event of excessive current which would be heat related.

Is there absolutely no visual difference between the wires? Post A picture.
Hmm... I'd guess this question will return a no as an answer but, do you have an LED handy that you could use in series with a resistor as a visual aid?

Unfortunately, I don't have an LED, but I have a motor. Depending on how I connect it, it will spin either clockwise or counter-clockwise (I think). How could I determine the positive and negative from that?
And no, the wires of the Motorola Charger were split, and both coloured black. Inside the black insulation, however, is just the standard copper colour.
This is the best illustration I could find: http://mohitjoshi999.files.wordpress.com/2009/08/080609_0658_dcmotorinte2.png
Clockwise has the positive at the top of the motor, assuming the rotor faces out (The page didnt specify but I would think that would make more sense).
Hope that helps.
EDIT: By rotor I mean the shaft.

I don't know, I'm kind of doubting it changes sides now since it's too fast.
By that diagram, I think I've found which is which. Still quite uncertain though.
If it's a typical dc motor it will change as you alter polarity.
If you have paper clips you can wrap two on the rotor, if they are different colour it would be even better. That way you could decern what direction it's turning.

Okay, I think I've got it. I've marked the negative (black wire) with some sticky tape.
What now?
Also, thank you so much
Since you have the polarity figured you you could go ahead and try it again on the old battery just to be sure if it can give you any indication of charging. If not try it on the xperia battery. Id suggest monitoring the temperature of the battery while charging by sense of touch, if it feels hot pull it off and let it cool before continuing.
The xperia battery is 5.4 Whr and the power going into the battery is 2.75W, so it should take 1.96 hrs to fully charge, assuming max current. So about 59 minutes will give you 50%.
EDIT: I used the xperia charger power instead of the one you're using
best thing to do is charge it in the car. rev the engine or get it up to 180km/h and that should cause it to start charging and since you have the custom kernel, it will turn on and continue charging. I hope it works, I had the same problem

Mine still gets hot but I haven't noticed any issues due to this.
Everything electrical gets hot due to the inefficiency of the flow of electrons through a conductive material. For chargers this is amplified as a great deal of power is going through them for a long period of time(if going from very low battery it is more likely to increase in temperature). My laptop charger would get so hot it could burn someone. I don't think this is really an issue unless you think it is hot enough to be considered a fire hazard.
Yes, it is normal for the Prime's charger to get hot while in use.
It shouldn't be melting-plastic hot, but it will be very warm to the touch while it is actively charging the Prime. Most chargers for any device (even phones) get noticeably warm while in use.
Mine gets so hot that it could pass as *famously hot actress*. Lol but I could get my eggs frying on it.

Good for you.
at least its not as bad as the iphone trust me haha that thing is bad!
Got up to 119F today, stupid hot day though. Extreme conditions, on my dash car dock. Normal usage is around 92F.
Casing definitely transfers heat well. My old Mt4G had the metal back and even at hotter temps you could barely physically feel it. Being thinner too probably doesn't help.

Mine gets warm, but not hot. My iphone used to get really warm where it would shut off, this has yet to get anywhere near that.
keep in mind that the S3 is a powerhouse phone. the S3 can match the processing power of some low end computers, and think about it.. those low end computers have a large fan. I would get a task manager and as long as your phone isnt constantly above 110 or maybe even 105 you should have nothing to worry about.

The battery?
---------- Post added at 01:32 PM ---------- Previous post was at 01:26 PM ----------
Ok lol I thought 105.3 on the battery was hot, but glad to see its not just me. its funny how with all these advancements in mobile gpu technology I still don't think it out performs my intel hd 3000 integrated graphics. Thanks to the android x86 I was able to run antutu on my intel core i5 2450m @2.5 ghz and scored a 21000. I highly doubt it was accurate as Im sure it isn't optomized and it fails to make use of turbo boost. Given this isn't a low end computer, but I still don't think we are that close. Apparently the new ipad's gpu is 30 percent slower then the on in the wii.
So as many of you know, or will find out, the S3 gets a bit warm, almost hot at times around the bottom third of the phone. I am waiting for the Otterbox Defender and I was wondering if it is advisable not to use it. Granted I know these things can handle high temps, would leaving the phone in a thick case with no heat dissipation and high temps create another blown phone (the phone that caught on fire)?
Let me know guys, really need a case on this, but not sure how the high temps will fare with the Defender. Thanks
I've been looking at the defender myself, my plan is to monitor temps for a while. If it runs hot I'll dremel out the lower section of the case over the CPU for heat dissipation. With the layers it should still be strong enough to protect the phone just fine with a portion missing.

I know you didn't ask me, but it outputs 500mA per the specs from the paper on the box.

That is just too slow. Wireless charging would be ideal in the future when it becomes vastly available within open areas not only limited to the small charging pad, but as of now it just does not have any advantages in comparison to a standard micro USB cable; more faster, portable, direct access to storage while charging, and most abundantly available.
Well, it does have the advantage of being convenient. I would just drop it off the pad overnight.
Otherwise, yeah, it has some room to grow. A lot of the problem is that quite a bit of electricity is wasted currently.

It's not that slow, why do people seem to keep complaining about it? If ur getting less than 5 hrs sleep at night, and ur battery is under 20% when you do shut down for the night, then yeah, you may have some difficulty with this.
Wireless charging has been just slightly faster than usb charging for me. I think that with that rate and the convenience added, it is more than worth it. I was concerned about it before I got the phone, but after testing it, the battery life is double what I'm used to, so I just don't need to charge it as often. I use my phone quite a bit through the day, of the charger at 5:30 this morning, no charging during the day and I'm still at 45%.

Really is there any wireless charger available for any mobile phone..?
If the phone supports inductive charging and/or has an inductive charging back that can be used.
I ordered the LG wireless charger but verizon accidentally sent me the nokia one. I actually like the nokia one BETTER as it is smaller and is black in color. It seems to work well. It def doesn't charge as fast as my wired charger but wireless charging is very fast as well. I took a 10-15 minute shower and it went up 5% which isn't too bad.

What are the negative repercussions from constant or intermittent charging? I understand that it's detrimental to let the battery drain completely before charging, but constantly putting it on the pad only to pull it off again isn't harmful?
