I have a power plug and sometimes charges and sometimes don't. It also gets hot after about 10mins of charge but it is charging.
I know there has been a few faults but has anyone experienced this charging sometimes and hot to the touch?
The charger getting hot is a good sign; that shows that it is working. The charger will get (very) hot during charging and will cool off when it is done charging.
My recommendation to fix the sometimes charging/sometimes not charging problem is to pull the cord out of the plug unit and plug them back together. The cord is a little finicky and so it might need to be reseated. Make sure the cord is plugged ALL the way into the plug unit (it can be a little hard to get them to be perfectly together).

I have called Asus on this issue and while they agreed to RMA the charger I just can't be without it right now so i wait. Chargers getting warm are normal, but chargers getting as hot as mine does is not normal and not good. I would estimate this charger is getting in the 160-180 degree range. Mine has also failed to charge on one occasion. One post i ran across said to change the polarity of the charger by turning it over so that the word ASUS is upside down when the viewing the outlet with the ground pin below the prongs. Seemed to help but not sure if its actually better or just wishful thinking, ymmv.

Turning the charger over does not effect the heating of the charger, it simply eliminates the possibility of stray AC voltage on the shield of the cable and frame of the TF. The heating of the charger is caused by inefficiencies in the inexpensive charger and fact that it appears to be working close to its design limit. A few tips that have worked for me.
Use an outlet that good air circulation around it.
If used on an extension cord. sit on a heat conductive surface not on a carpet.
If tablet and dock are deeply discharged, charge separately and allow charger to cool between charge sessions.
If the charger gets too hot, it appears to shut off. Allowing it to cool generally gets it going again.
ASUS said i spoilt the power plug
sigh...i bought 2 units of EEE PAD **** TRANSFORMER...2 of the power plugs also loose...after 2 weeks of use...they said i spoilt the plugs and is not under warranty..i need to buy replacement...
how low quality is ASUS product or eee product...????

The charger and plug for the wall are a 2 piece unit. Ensure that that end that contains the wall prongs is seated all the way down. There is a line between the 2 units. The pieces on both sides of the line should be flush.
Regarding temperature, mine gets pretty warm. Warm enough that I would not want to handle it.
My Eee pad came with a UK power adaptor. I have noticed the adaptor gets very warm even after it has been charging for a half hour or so. It's a lot warmer than I would expect. Is this normal behaviour?
Seems to be. Mine gets warm when its charging, when the TF isnt plugged in or the TF shows charged it cools off. Not hot enough to melt anything but definitely warm to the touch, even warmer than my laptop adapter. Although, I should note it gets nowhere near as hot as a kingston laptop adapter I rented from Best Buy a while back.
My adapter gets super hot when I plug in my tablet when docked and both have dead batteries. After seeing pictures of people's adapters melting, I won't let mine charge from dead unattended.
i believe its warm due to the high charging rate. considering the fact that it only takes 4 hours to fully charge a tf from flat.
from personal experience, charging batteries at higher C the charger itself will warm up.
I just got myself a Nokia DT-900 Wireless charger (Got it at a clearance at the Nokia store) for use with my Nexus 5 and my Nexus 7.
I charged the nexus 5 with it now. While it charges perfectly, even with a case on, the back of the phone gets a little warm. Not hot, just warm. I was wondering if this is any cause for concern, or if this is normal. Have not tried with my nexus 7 though.
Does the nexus 5/7 work perfectly with the Nokia wireless charger, or is it Incompatibility that is causing the phone to warm up a little?

As it's an LG, I doubt it's any different from the Nexus one. Both have the same specs. Have emailed Google regarding this, their reply was the standard 'We do not recommend using Non-Nexus chargers for Nexus devices'. I told them all QI chargers were actually supposed to work, and am awaiting their reply. Will follow up on this.

I bought a QI wireless charger when I purchased the phone based on excellent reviews on Amazon. I've since stopped using it just because of random overheating and generally the phone was warmer than when charging via USB. It was a feeling that overtime my phone would suffer.

my thoughts exactly
Wireless charging, by its very nature, generates a small amount of heat. It is perfectly normal for your phone to get a bit warm whenever you're charging via any means, but especially when wireless charging. The key is the phrase "a bit warm." It should never be hot to the touch, just warm. The phone was designed to handle this, and there will be no adverse effects. In fact, the heat generated is much less than is generated by the CPU during heavy use (such as during a graphic intensive game).
I regularly use my phone with the official nexus charger (in my car), the Nokia DT-910 (the stand-up version of the DT-900 -- my main overnight charger), and the Samsung S-Charger Pad (at work). All are perfectly compatible with the N5. In fact, the only name-brand charger I'd steer clear of is the Tylt Vu, because there have been numerous incidents of overheating with that charger (i.e., the phone gets very hot to the touch).

Yep, I read online that the Tylt Vu has some issues.
I spoke to Google about the Nokia charger, and they said the temp of the phone is normal. They did warn me that the Nokia does not cut charging automatically when it gets to 100%, and that I should Take it off manually
Using a case increases the distance between the phone and coil which can cause the phone to heat up even more. Even wired charging heats the battery so some extra warmth from the 25% lost energy seems normal.

Lots of people who use wireless chargers say this but I am still skeptical. I would like to see battery capacity tests from two of the same devices. One that was only charged with wireless charging and the other only charged via USB.
My money says the wireless charged device will have significantly less battery capacity than the usb charged device after 1-2 years of use.

Yes, But seeing as most of us use the phone for only 1-2 years, I personally don't see a difference. Maybe the battery will lose capacity over time, but that's going to happen anyway. This will maybe speed up the process by about 20%.

That may be true, but that argument lies on shaky ground, since there are a lot of other ways you can (theoretically) reduce battery life as well. In theory, not allowing the battery to drain completely during each charge cycle, or not removing the phone from the charger the instant it's fully charged can reduce battery life, yet nobody charges their phone that way. There's also the counter-argument that plugging the charging cable in every single day can prematurely wear out, or break, the (very fragile) USB connector on the phone, which would result in the inability to charge at all. (I went through SOOO many Galaxy Nexuses... Nexes? Nexii? Whatever... because of that issue.)
The point is that sometimes, convenience takes priority over the possibility of slightly reduced battery life, and it's hard to argue against the convenience of wireless charging.
Plus, as Srivas95 stated, most of us will move on to the next device long before any such battery degradation becomes an issue.

What you say is right, my Nexus 5 has been with me for just 4 months and I can already see that the jack is kind of loose. That is one of the reasons I got a wireless charger in the first place.
I'm coming from years of android phones and have always purchased wireless Qi adapters for them. After experimenting with several different brands of receivers over the years, I became a believer in the Nillkin brand. They cost a little bit more but they are way better built. I have always bought this receiver and have never had a single issue with mine or my wife's galaxy notes. I recently picked up a note 4 and after using it for a few days, I realized why I stay with the note brand. Absolutely amazing phone. Naturally I waited till Nillkin made an adapter for my phone and picked one up.
I placed it on charge the first night and when I picked it up in the morning, I nearly dropped it due it being so hot to the touch. That has never happened in any of my phones. Obviously something is not right with this thing.
Here's the weird thing....
I'm running "SmoothKat" rom but have a stock rooted back up. Oddly enough, when I restored to stock rooted and placed it on charge, It would still get quite warm but nothing like it was on the custom rom. I also tried turning off Fast charge option but no dice. Anyone have any advice? Is anyone else having an issue with the wireless charging making the phone hot?
BTW I'm using the TYLT Vu charger.
Thanks in advance...
Same charger here, using the OEM charging back. No heat issue.

Weird... It has to be this Nillkin receiver. I just searched around and noticed the Nillkin receiver has a significantly larger output of 850Ma. Most other receivers are 600-750 max. Could that be the issue?
I have a couple of receiver cards too, no heat issue with them but could not get tap to pay to work.
Hmmm that's never happened to me, and I have the same Nilkin charger. Maybe something with your phone?
Was the charger equally as hot?
Very strange. It seems the issue has worked itself out. I woke up yesterday and the note was slightly warm to the touch. This morning, completely normal temperature.... Weirdest thing... its like it learned what was going on in the past few days and fixed itself.... Mind blown.
Thanks for the help!
I had the same thing happen. I was using the OEM back with my TYLT, Airdock and Qi infinity chargers and it was running cool. The phone was too thick for my case so I switched to a Enpower transmitter with the original back. It was much slimmer but got WAY too hot. (I only tried it on my TYLT and decided not to F with it anymore.)

That's really weird. It may be something with our phones? I don't like the bulkiness of the oem cover so I was determined to figure out what the heck was going on. Shame I wasn't able to get to the bottom of this. Ill keep this thread updated as the days go by. I'm sure we aren't the only ones that had this issue.
Maybe they use the extra thicknesses for heat dissemination. It has a metal plate near the bottom on the inside, maybe that acts like a heat sink. I am sure their engineers did not take the decision to increase the thickness lightly, there must be a good reason...
And yes they should have baked it in by default. A flagship phone needs this built in, they were just greedy for accessory sales I guess.
Well, I'm glad the problem solved itself for you, OP. I don't know why that would have ever been an issue, but hey, if it ain't broke, don't fix it.
Same problem here with *Nillkin receiver, my note4 get really hot on charge.
My nexus 7 gets hot when charged using Nokia wireless charger. It stays hot even after charging is done. As if it won't stop charging so the energy needs to be dissipated somehow how so lt just generates heat.
I would NEVER use wireless charger on my note 4 because heat kills battery life.
I use a cheap ebay charger and wireless receiver that fits into the normal backcover...
It warms up while charging but nothing too hot. Just like charging normally by cable... Ofcourse, the cheap wireless receiver only gets 600ma max from the wireless charger.

thats just silly. the note 4 stops charging and cuts off the qi charger when charging is done. you can see the wireless symbol disconnect.

Then the fault is with the Nexus 7 ? Sometimes i pick it up from the Nokia charger hours after it is done charging at it is still very warm, even almost hot.
Tbh I wouldn't be surprised. The nexus 7 I have has lots of issues like random reboots, touch screen issues. Many people have these problems. ASUS really screwed up the 2013 nexus 7.
Wireless charging is awful on this device. No matter what case (or even no case), my phone must often does not charge wirelessly. I've tried multiple chargers. I get the "connected; not charging" message. Sometimes it works, but seems to need to be in the exact spot. Even then, it often stops charging after a while or drains faster than it charges.
Any insight or solution to this?
This is a stock pixel 7 pro, bootloader still locked. Bought from Google store and activated on T-mobile.
What wireless charging pad are you using?
I was having all the same thoughts as you. Had a couple Samsung "fast" wireless chargers. However, bought a new one Costco that's not Samsung and it works as expected. Never have to realign or wake up to a dead phone anymore.
my rooted p7p with tq1a.230205.002
is charging well with wireless pads and wireless powerbanks.
always heating up p7p tho
I don't know why people like using Samsung but I prefer other brands

A variety that all worked great with my Samsung s20. Ankers, Samsung, and a few generics that worked better. None work well with the pixel 7 pro

In my case, I figured out my wireless charging is unstable if my phone is in any condition where it might get at all warm. The Pixel 7s are just lousy at staying cool, and once the temperature rises to high 30/low 40C (which doesn't take much at all), wireless charging is severely throttled if not completely stopped. So if it's sunny out, I understand my phone won't charge in my car mount. The sun just makes it too hot, and it won't bother (no matter how cool I keep it in my car, direct sunlight on the phone is too much). If it's sitting on my wireless charger and I decide to try and use my phone while it charges, I understand odds are VERY high it will get too hot and stop charging. And if it stops charging because it has overheated, I know now to give up rather than keep readjusting it on the wireless charger, because even if it's not charging, if it's trying, it's still making the phone hotter, which is making it take even longer to cool down and resume charging. So I just take it off and don't bother putting it back on until it's gotten a chance to settle first.
It's finicky and irritating that their flagship has such lousy thermal control, but knowing that my wireless charging issues are linked to my phone's temperature has helped me understand how to keep my phone charged. Those who only charge wirelessly without ever trying to use the phone and only in particularly cool environments may never observe any wireless charging issues at all.

I noticed this too
I find Power saver with less brightness helps, but if it gets hot it's not charging at all
No problems with 2 different wireless chargers with a transparent case.
I measured the power usage with an external device and its mostly the charger uses 14 watts power between 0 and 80%. (don't forget the energy loss with this technology!)
No real overheating. But placing the device correctly affects the power draw a lot.
I agree. It's terrible, no matter what charging pad i use, it always glitchy.
Not to mention, the reverse charging won't work properly either. Plenty of time i need to recharge my buds while travelling to no avail.
I struggled with wireless chargers for P7P too, I tried at least 4 with varying degrees of success but ultimately I just ended up using some of the store credit I got for buying to the phone to get a Pixel Stand 2 and it works great.
I can happily say : MARCH RELEASE FIXED MY WIRELESS CHARGING ISSUE.
