I have not noticed this before i sent my Transformer in for an RMA, but whenever it is charging from a low battery percentage the back of the Transformer becomes warm to touch. It is not warm enough to be uncomfortable but it is noticeable, and i was wondering if this is normal?
When charging from complete 0 or very low for a long time mine gets warm too, it's normal. Especially since the charger is a 15V, that throws out alot of resistances. The charger itself also gets very warm, but has a built in switch that flips if it gets super hot, so I wouldn't worry about it too much.
Happens with mine too. I always assumed it was normal.

Hi,
My TF101 seems to get warm when charging. I didn't notice this with the other ones I used, but perhaps I just missed it. Can anyone else confirm or deny this happens with theirs please?
Thanks.
Yup it happens, nothing to worry about, it also gets a little warm when running a CPU intensive app.
Yeah, mine heats up a little bit when it's charging as well. I can still hold it though, so I'm not afraid of it being too hot.
I decided to do a quick test to see what the temperatures really were... The unplugged temp was after I had left the screen on for 30 seconds and haven't run any games/applications recently.
Plugged in temperature was measured after being plugged in for 5 minutes and screen on for 30 seconds.
Battery temp unplugged: 24~25C
Battery temp plugged in: 26~26.5C
So not too much difference but I'm sure if you were using it while it was charging, it would heat up a lot more.
It's a common effect for many portable device. My EVO 4G gets fairly warm, my old iPhone 2G got super warm, my laptop gets piping hot, my Sprint Overdrive gets a bit warm. The only portable device that doesn't get warm while charging is my BB 9700.
Yep, mine gets warm to when its being used, in the right-hand quarter in back. But when I say "gets warm," I mean literally just a tad warmer than the rest of the unit. It never approaches "really warm," and certainly not "hot." I can't say if the Xoom ever gets warmer when in use because I've always used it in its case.
it should fine..
the charger itself is not warm..it's actually very very hot...

I heard about ASUS update FW this week.
However, you maybe go to RC (repair center) for updating the newest FW.

Never really felt it before you mentioned this but... you are right, it is really hot.
Also, when I touch the dock lightly while charging, I can feel it vibrating.
Mine is always at about 101 degrees just surfing etc? is this normal? or is it too hott? games get to about 110 or whatever. Charging about 104 degrees.
Also, I noticed a bubble under the battery on the phone. Its just like the sticker didnt stick and made a bubble. I basically flattened it down, but it dont look perfect, but should I be worried about that?
Reason Im asking is phone feels warm and battery is draining. Damn we really need to get rid of this BLOOOAT.
I found a primary culprit to be screen brightness. I'm not saying WiFi and processor intensive apps won't do it, or GPS, but I have had to settle for about 40% screen brightness or I get heat and a battery that drains really fast.
Barely gets warm, might be my own heat from my hands. Using wifi with screen brightness low. Does get a little warmer charging, nowhere near hot
My Phone too gets warm during use espcially using GPS while driving and charging. 45degC ~ 113degF was the max so far.
Screen brightness seems to have an effect on warmth of case, for sure, as well as battery life, obviously.
I think mine gets the hottest when I am surfing on an adapter, using WiFi, and GPS. That's only logical.
I'm thinking T-Mobile pushed something to my phone over the last couple of weeks though since it does not get as hot or blow through the battery as fast, and they also solved a corrupted video issue as well.
When I keep my phone on & just charge it up while its idle, when its at 100%, the phone is hot to the touch. Once I take it off, it cools off in 5-10 minutes. It also starts to overheat when I play games on it for at least 5 minutes. What could be the problem?
Do you have a custom rom or kernel on the phone. Mine gets mildy warm every now and again but nothing serious.
Id suggest reverting back to stock rom using your ruu and use it for a bit to see if it happens again.
i had a similar problem. my phone would overheat and not charge or charge fast enough. also after a short use the battery level would plummet. i fix the problem by changing to a new charging plug.
It shouldn't get that warm at all.
Infact, I noticed that it actually cooled down once I plugged it into the charger. I was playing a 3D game and I noticed it was getting warm, but also the battery was getting low, so I plugged it in and kept going for a bit longer, the phone actually started cooling down. I thought it was the game making the hardware heat up, but in fact, it was the battery heating up due to the power drain
Perhaps a custom rom could cause it, but I am already running mikes 6.5.2 with the 1.5Ghz firmware. But im sure others will vary.
Perhaps, if nothing else, and you're ok with taking the back off the phone, check the contacts, both on the battery and the phone, make sure they are clean. Resistance can cause heat.
Hi Guys,
I remember reading a post about this before but can't bloody well find it
With my tablet docked, they keyboard battery is draining much faster than my tablet resulting in a useless dock fairly quickly i.e. 0% in dock vs 80% in tablet. This seems quite a gap - I'm running stock, not rooted. Is there anything I can do to improve this? I don't remember the charge gap being so vast in my first TF700.
Any advice/suggestions are most welcome.
Thanks.

Been discussed before. Dock still operates at 0%, no need to keep a charge in there. It acts as the sacrificial battery, making the tablet use that power first, so if you so choose, you can continue using the tablet w/o dock or with dock and get the maximum battery life both ways.
Thanks Nick, I thought I noticed my keyboard wasn't working before when at 0% but will give it another whirl tonight. If it does work then bravo on Asus
i recently bought the dock and i also find the battery drain rather strange. i always turn off wifi over night and the battery of the tablet usually stays exactly the same, e.g. if i fully load the tablet before going to bed, i have like 99% in the morning without any drain.
yesterday i went to bed with dock 80% and tablet 85% and wifi off. today i find the dock left with only 40% and the tablet with 82%? is this normal? i guess i have to take them apart all the time over night otherwise it just drains too much
Definitely is not normal - I leave mine docked overnight with wifi *on* and I only get a percentage or two drain...
To start with, 'd look (with CPU Spy) to make sure you tablet is deep-sleeping properly.

That's odd. Maybe some process kept running overnight.
Check that the following are set:
- GPS to OFF
- IPS+ OFF (set it to IPS mode. + drains 10% or some overnight, even when off.)
- Mode to Power Saving!
- Shut down all active processes (taskmanager has this convenient one click clean.)
- Check that media players have shut down properly in the Settings/Apps/Running apps menu. Also make sure they're not still cached (VLC tends to do that...)
I think that this is normal behavior. I notice that after using the device for a while, when I shut it off the dock battery actually charges the tablet battery. The charge light on the tablet even indicates that this is the case. I believe that is by design.

The charge light is indicating the tablet is (primarily) running off the dock battery. EDIT: although this is in essence a correct statement, I have paid more attention to it and noticed the dock does indeed charge the tablet (when not in use) -- it's a few percents, but nonetheless, it charges. Mea culpa..
The capacity of the tablet and dock batteries is different, so discharging under load will differ as well. I guess the behavior you are seeing is by design, and, to some extent preferable to the situation I have had since the beginning: my tablet depletes faster than the dock, at least initially, and that was what most of the early adopters were seeing, as well. This of course led to some discussion.
The behavior we noticed seemed somewhat counterintuitive, since it meant we would have less battery capacity on the tablet if we would choose to undock it -- as opposed to your situation, where you have as much battery capacity left on the tablet as possible when you choose to 'travel light'. I'd prefer it that way. ; )
So, the dock depleting significantly faster is nothing unusual nor anything to worry about. I do have to concede, though, that my battery drain is far less than some in here report -- it has been going for three and a half days with moderate use now. (That's OK, I guess, given the fact that I currently am in nightshifts and do not have to time to tinker as much. Even when I *am* tinkering, though, the batteries routinely carry me over two days, easily.)
My dock and tablet have weird battery usage.
So my problem is really weird I think, but maybe you guys can confirm or offer any fixes. I have tried charging the tablet and dock assembled through the dock port and gotten both batteries to 100%, but then while docked, the tablet's battery drains faster and the dock;s remains at 100%. As the tablet's battery gets to around 70%, the dock's will start to deplete but very slowly. The dock will only go to 70%, and the tablet will drain completely to 1% and then shut off even though the dock still has 70%. I then undocked the tablet and just charged the tablet back to 100% without doing any charging to the dock. After docking the tablet, it shows the tablet at 100% and then the dock at 70%. This time the tablet drains to 1% and then shuts off with the dock still at 50%. What's going on here or is it normal or is there a setting that I'm missing? I thought the dock was supposed to extend the tablet's battery life time??
My Samsung S8+ gets how while wirelesscharging. Is anyone experiencing the same issues?
Mine gets warm but not exactly hot. There will be extra heat due to the tech involved but it's okay unless it's uncomfortably hot.

Did some measuring: The device is at 50°C on the back.
if thats warm but not hot I wouldn't worry. So does mine.
Using the genuine S7 style fast charger I leave mine on the charger when at my desk well beyond full charge at most it's gets slightly warm

Mine gets warm but not too hot with the new convertible wireless charger.

Mine gets a lil warm, only time it does actually.
It's because some of the electricity that's transferred wirelessly turns to heat, it's a problem on every wireless charging device. Heat is poison to the battery, the best way to charge the battery taking in mind durability in the future is cable charging with fast charging disabled, no matter what fast charging technologies are invented, slower charge speeds are always better for the battery's health
