As the title would suggest, my poor GS2 gets VERY hot when charging. Not all the time, but often.
If I charge from my PC's USB, it doesn't, but when I use a mains charger, it overheats.
When I finish my night shifts, my battery could be down to 20%, so when I go to bed, I plug in the phone, set it's alarm and pop it under my pillow, like I have done with every phone I've ever owned without issue. I wake up during the night and pull out the phone to check the time and almost leap out of bed because of how hot the device has become.
To make matters worse, it's discharged in battery power. This morning was the final straw, as when I checked the phone and it was red hot, it was also dead. I held down the power button and booted up the phone. It showed 15% battery left. I know people say that when it's charged, remove it from the charger, but it isn't practical. Besides, I've never had to do this on any other phone I've owned. This is unacceptable for me to rely on any more. Is this a common issue?
Or my fault because I have rooted the phone the tried custom roms/kernels/modems on it before?

1) change to a diff kernel and see for the issue.
2) well charging from 10~20% to full 100% will lead to heat up the phone than charging from 50~60% to full 100% , hence also check for the same and see

I should have mentioned. This happens on any Rom and I've tried 4 kernels and still the same issue. Only thing I haven't tried, is going back to Samsung stock rom. Going to try that today, see if that solves it and report back.
Like Samsung told my wife "when it gets hot dial *#*#4636#*#* and note the battery temp".
Is it still under warranty

Well the PC's USB output would be limited to .5 A whereas your wall charger could provide 2 A. This might just be normal IMO, although I can't say that my phone gets ridiculously hot during charging. As others mentioned, I would check the battery temp.
The issue is already in his post and the solution as well.
1) The S2 has the tendacy to get hot. Its all very compact and there are no internal ventilators so the S2 dissipates heat to the rest of its body.
2) There is a Power difference between the charger and a USB cable. The charger gets hotter since it delivers power directly of a higher voltage and slightly higher amps then a usb port.
Your issue comes from one sole thing. Your bed. beds have very poor heat dissipating abilities, in fact, it has none. Considering no fresh air is delivered to your device, because it is stored under your pillow. Not to mention your pillow, the rest of your bed stop heat from leaving and it builds up. Ontop of that your heavy head is resting on it, pressing the pillow tight around the device.
in short, it has no way to relieve the heat. There is a simple solution of a non technical matter. Don't put the darn device under your pillow.
(the same counts to people that use there laptops on there beds pillow or covers without a proper cooling matt, before wondering why the hell there device shut down all of a sudden.)
The problem is you put your phone under your pillow. I made this mistake a few weeks ago and the phone was too hot but no problem when i charge it somewhere not under the pillow
I agree, I should stop doign that. But one question, if that's the case and the getting hot is normal, then why did the battery drop from 100% to 8% while plugged in?
Your cooking the battery, thats why.
i'll admit i charge my phone and leave it ON the bed so air still circulates but it did used to get hot. Not sure if any changes i've made such to things kernel, ROM, modem or undervolting has caused my change in temps but my phone never feels warm anytime day or night weather its on charge or not where as my partners phone (stock sgs2) does get hot using the same charging habits as myself

For the AC charger this problem is known: if the charger is of poor quality it will generate too much 'noise' (ripple) which disturbs the electric field used by the touchscreen. However the original Samsung charger is of good quality and does not have this problem.
Experiencing these kind of problems when charging by a laptop USB port however is abnormal.
Interesting.
I bought an official Samsung charger off ebay, and it produces the same results. Much to my frustration.
Leaving it plugged in all night however was fine, I placed it on a shelf and the phone was actually cold when I woke up. I'm just worried the battery is ruined. It seems to drain quite quick.

I had this happen to me once. For me, I had been using the phone constantly for a while one day. I plugged the cord in to charge it and also kept working on it. I was using apps that pull the battery hard. I could feel the battery getting warm, and I noticed that even with it plugged in, the battery was still going down. I closed everything, unplugged it, let it cool down, then tried to charge it again and it was fine.
Not sure if this will help you; just what happened to me.
edit:
I was using A LOT of resources when this happened. Havent had it happen in a long time.
I unplugged from charger, and plugged back in and now its charging like normal again. Weird. Now, if I could figure out how to get away from the Android OS battery drain...
Typical behavior while charging if being used. Depending on what you're doing, you can expect it to charge slower or actually discharge, as you witnessed.
A couple common issues from other electronic devices.
You are drawing more current then the charger is providing.
The cable is not fully seated so there is either resistance in the
connector, lint in the way, surface corrosion in the connector, etc.
I once plugged mine in, set it down and left it for a few minutes to find it really hot and battery draining while charging. I opened set CPU and it was stuck at 1200. Unplugging it didn't fix it. I had to reboot, but it was fine after that.
Other than that the only time I have seen the battery go down while charging was Netflix over 3G over MHL.

Surround electronics can mess with the charging and cause things to heat up. Also, make sure the cord isn't running parallel with charger. Check the manual to see what I mean.
Also the farther electricity has to travel, the hotter it gets. Try lining it up better.
I have zero trouble with my wireless charger, same LG wcp700 as you. And I've got a case on mine as well. You've definitely got something else going on.

Mine doesn't do that either. My suggestion is to pull it off of the charger as soon as you're at 100% and don't put it on until you're below ~10%. Magnetic fields inducing current causes heat to be released in the wires and surfaces -- it's something you can't stop if it's happening. I'm sure HTC took (some of) all the necessary steps to lessen this, but it still happens.

I wouldn't be making a habit of waiting until 10% to charge, you should get better battery life over the long term by charging before 30%
My phone becomes warm to the touch when charging, but not hot. I have left it on the charging pad while fully charged for hours and haven't had any issues with temperature.

I VERY much disagree with you -- all of the phone manuals etc. say to wait until the battery is dead until you charge. The higher the battery is when you charge the more detriment to the battery life. With modern batteries, however, it doesn't very much matter because they've been designed to be better about this and you won't get much more time out of your batteries by discharging completely before charging.

There are varying views on this, but I was told never to let a LiPo get completely depleted. Beyond all of that, I feel heat is far worse for the battery. It looks like I am not the only one with problems with the tech, others are experiencing the heat issue:

mine gets hotter than just plugged into outlet but not too bad. not like fire lol
Today I took my DNA for a spin using google maps. And to power the beast I used a 2000mA momax charger. To my surprise halfway through the trip I noticed my battery level had halved. I remember seeing the charging icon on the battery so thought ok its charging it.
But when we arrived after a 45 mintue drive i lost over 50% battery It seemed it wasn't charging after all. The phone was extremely hot
Did it get too hot possibly while driving and stop the battery from charging as a thermal safe guard from overheating? I'm on the stock kernel. Anyone had this issues like this? And does anyone know the MA rating of the official DNA charger? I'm in New Zealand so i cant just pick up the official charger or anything like that.
If i cant use the GPS without the phone charging it will make it unuseable on long trips
Edit: Problem found, phones gets too hot on the dash and running GPS it will throttle and not allow the battery to charge. Thumbs down to HTC making a phone with GPS that can't be used for more than 20 minutes or your phone overheats.

the rating on the HTC charger is 1000mah.. one thing i have noticed that some higher MAH chargers will actually cause the phone to charge in "USB" mode.. when you plug that charger in check the battery settings screen and at the top it should say charging AC or USB.. if it says USB then that is likely your problem since USB charging mode is much slower than AC charging mode.
Awesome tip. Never knew that, thanks!
Wow thanks very useful info indeed. I think i might be over doing it and making it overheat. I will try a 1000mAh charger in a few days and see if that solves the issues!
So the problem doesn't lie with the actual mA output of the charger, but with the way the charger is physically pinned out. On "fast" chargers, that is, chargers that can deliver more than 500mA of current, the center two data pins, D+ and D- are shorted. This short tells the phone that it's plugged into a dummy charger and allows it to draw more current (I believe the DNA can draw a max of 1 amp when in AC or fast charge mode). In a computer USB port, these two pins obviously aren't shorted as they are the data pins. Without the short being present, the phone assumes it is plugged into a computer where USB 2.0 specifications allow for a maximum of 500mA of current draw, so the phone software limits the charging rate to 500mA. The flaw in many aftermarket chargers, even the super high power ones, is they omit shorting the center two pins, resulting in the phone only allowing 500mA of current draw. This is a problem with both car chargers and some home chargers, especially the multi-port chargers designed for iPads and smartphones. Apple uses a different pinout for their high speed charging that isn't as simple as shorting the two data pins, so many Apple branded or "compatible" chargers don't put Android devices into fast charge mode.
For a car charger, my personal favorite is this Motorola one from Amazon. It provides up to 950mA of current, is genuine Motorola OEM so it's built well, and best of all is only $5 with free shipping if you have Amazon Prime. The only drawback is the LED is kinda bright and annoying, but I keep it in the outlet inside the center console so I never see it. http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA/ref=sr_1_1?s=wireless&ie=UTF8&qid=1356666975&sr=1-1&keywords=spn5400
Yeah I use that charger too. Works well. I recently bought a dual USB output one that claims it puts out 1amp..but my phone shows USB mode. Is it only putting out 500 then?

Thanks for the info, still not luck for me. I brought a brand name 1 amp charger and used it again. It charges well to begin with. But after about 10 minutes the notification LED in the phone will start to flash .... Then it seems my DNA is not charging at all. Status bar tells me in the beginning it was not on USB charge. After the 10 minutes no charging detected at all. Its as if the droid disables charging.
I will check the cable too again and see if that was the issue. It might be the charger and or cable. But the first charger charged my Note II without any issues and fast. It never lost battery %
And again my DNA was scorching hot. Which seems to me more of an a throttling thermal issue. Its reaches xx temp and charging is disabled. Does the flashing led mean something? It was a sunny day and its summer here in New Zealand so the droid just got too hot maybe? Being black on the car dash in the sun cant help it.
I love this phone, and have my note II up for sale but if i cant fix this issue it seems GPS and Nav is a no go for me. Which is not good. I travel a lot.
Update,
I did some further testing and the news is bad I used my standard HTC DNA charger, and tried to repeat the conditions. Got my phone hot and low and behold. On the charger it will stop charging once the phone gets too hot. It will flash a green light, then orange, and repeat.
in other words if you want to use this phone in summer on your dash as a GPS you might want to think about running the A/C on it at all times
Can other please test this? Maybe i just have a faulty CPU, but i think its a built in thermal safetly feature once the CPU gets too hot it will not allow you to charge it. So in other words if you want to use this phone in summer with sunlight on your dash as a Nav/GPS think again ;(

This sounds right to me. My last 2 devices had the exact same issue when heating up. I do believe that fast charging really heats up the battery, so once it hits a threshold, it stops drawing power in order to cool off. Don't want a battery exploding in your phone.
The GPS radio can sometimes draw a bit of power, though it is much less on newer phones.
I digress, I really do think that in most cases, heat is the issue.
Its a very sad state of affairs, I cant use this phone as satnav / GPS without loosing a lot of battery life. Seems its only good for winter GPS when used on the dash in the sun of summer it will just over heat and not charge. Very poor if you ask me.

Try testing your phone at 'room temperature' (75 F, 30C), if your phone overheats using the GPS in this case, then you should return the phone because it is not normal.
If it is overheating on a hot dash board, ALL of my phones have done that. You can try blasting the wind shield vents to counteract the heat.
The DNA is normally great, but either your expectations are a tad unrealistic or your phone needs to be swapped.
A solution would be to mount it in a way that isn't in direct sunlight, like using one of those vent-mounted adapters. Then if it got hot, you could put the air on and it would cool it down.
Another option would be to either turn the brightness down, or to completely turn off the display, unless of course you have no idea where you are, and need more than just the audible directions.
But really, it sounds to me like your specific phone is just prone to overheating, and needs to go back. I haven't had any temperature-related functional issues at all.
Sure, it's gotten warm. But it's never failed me as a result of being too hot.

Well its summer here and its not taking the suns heat and being black doesn't help. I will see if I can move its position or place it over the A/c vent of the windscreen.
Wait till summer in the U.S and you will see more threads like these i think. I only comment its poor because no other phone of mine has done this in the past. Maybe mine is faulty.
Used mine for over three hours (one-way) using GPS/Maps full blown with no trouble or heat at all. I was also texting, surfing, playing games and talking on the phone at various times and had to plug in after awhile using the usual car charger. I don't like to get below 50% if I don't have to. Anyway, no trouble on the way there and no trouble on the way back.
HTC has always had the best gps radios I've ever used. My wife's GS3 still can't get as good, fast, and pinpoint lock as my DNA (or my Rezound for that matter).
As always, YMMV.
No offense man, but who the hell leaves their phone in the sun and expects it not to overheat? haven't you ever left your phone in the car in the summer and come back to a red triangle or a high temperature sign?
The key to keeping your electronics alive is to keep them cool. Your phone is just like your computer...you try to keep the temperatures as low as possible at all times.
I have a generic cigarette lighter adapter I got off ebay. I used my the google gps on my phone to a store in CT for the wife and then a trip to Boston, well over 3 hours worth of continued GPS use. When I unplugged the phone when we parked in the garage I had a full battery and the phone didn't appear to be any warmer than playing a regular game.

That's how every phone works. If you are using it in a hot environment and in direct sunlight it will try to cool itself down by stopping charging.

Sorry bud, you cannot expect to leave your phone on the dash in direct sun, while using GPS AND charging and not have less than optimum results. You are KILLING the efficiency of your battery by allowing it to overheat continuously. Keep it cool man!
People will find anything to complain about...
I love my Mega. It is by far the best phone Ive ever had. But, the problems I have with the power usage and management on the device are a total nightmare.
1) The discharging nightmare:
The battery lasts NOTHING. Basically I get about 5 hours of use.. maximum.. no matter what I do.. and I have slimmed down to the ROM to having that NOTHING active.. I literally am left with active 6 services and I monitor CPU usage that is always near zero with NO apps hogging resources. From what I monitor on the device's battery usage, it's clearly always about 90% from the display! And yes, I dim the screen as much as I can of course, but usually not below 1/2way.. I hate screens too dim. However even just on standby with the screen off I still lose about 5% to 8% of battery an hour. Worse, even with the device Powered OFF, I still lose about 20% of battery a day. The ONLY way I have found out to control battery drain completely, is to take the battery out. That's it. Anyone else with similar symptoms and a fix or, is just that the stock battery totally sucks??? Also, any other off brand batteries are any better?.. (not the fat ones rated at much higher amps but that have an extra bulge.. that I don’t want)..
2) The charging nightmare:
This to me is the worse problem. It is bad enough how quickly this device issues battery, bit not nearly as bad as trying to charge efficiently again. I now have tried 3 different chargers/brands (and cables) to try fix the charging problem that is, it takes HOURS and HOURS to charge the battery. I am talking 5 to 6 hours to get it charged and if the screen is on and Im using the device it actually charges NOTHING at all and still keeps discharging (albeit much slower of course)... the fact is that the charging process is so pathetically slow that is less than real-time which means, with the device connected to power supply, the battery STILL drains if I try use it. This is absurd. However, mysteriously enough I have found ONE way that charges the phone super fast.. using a SONY External Power Pack (model CP-F1L) rated at 2200mAh. This is seems crazy because the power output of an external power pack should be much lower than the stock (and other Samsung) USB chargers.. but, it's what works.. the ONLY thing that works. And I have noticed that when connected to a USB Power charger, the Mega's Red LED light turn on faded.. however, when connected to the SONY External Power Pack, is bright red. Clearly more juice going in.. or something like that. Again, anyone else with similar symptoms and a fix the charging time, or, any good recommendation on a extra strong USB power adapter/charger that will make this thing at least charge faster?
Thanks in advance for the input and advice:silly:
Sounds like something is not letting your phone sleep or the battery is defective. Try putting CPU spy on it and let it set for a while. Then check to see if it is getting into deep sleep or if it is even stuck at a certain frequency.
There is an app on the playstore called Galaxy charging. Try it to see what rate it is charging. Though with the rate your phone discharges, the charger may only being supplying an amount just over the drain rate which is why it takes so long to charge.

I would flash the stock rom back into your phone and see how the battery works then as this not normal as mentioned by other members as I am still on the stock rom but rooted only and I have great battery life.
That is were to start by flashing the stock rom and if no change then battery or maybe a hardware problem.
Did you have good battery life before you starting flashing with the phone or did this occur after the stock rom was removed and custom rom with stuff removed to gain performance?

You could try to remove the battery from the phone for about 5 secs and re-install and see it that helps as sometimes if you take the charger off as soon as it is done charging it might not show 100% at times when booting as I leave mine on for a bit longer and it seems to help..even though charge light is green..I leave it longer on.
If your phone is rooted get a app called battery calibrator from the google store as it is free and install it and just before you shut down the phone to charge wipe the battery stats with this app and then shutdown phone and fully charge and then see how the battery works after the battery stats wipe as that can usually help.

Thanks for the tip. Installed the app you recommend, now I understand better. With the stock Samsung USB charger I get 420 readings. With the other 2 chargers I get 500 and 540. However, with the Sony External Power Pack I get 1900!..no wonder it charges super fast with it! My question now is what's up with all the USB chargers I have? I even tried my old Galaxy Tab 7 charger (strongest rated charger I have) and still only feeds 480. This is all so bizarre. So, where to get a super strong charger for the Mega?
(sorry.. by whatever reason my reply got posted 4 times.. so strange. I try delete the first three but cant)..

Thanks for the tip. Installed the app you recommend, now I understand better. With the stock Samsung USB charger I get 420 readings. With the other 2 chargers I get 500 and 540.

Usually when this happens there is something wrong with the USB cable not necessarily the charger. Is the sony cable a USB type cable or a hard wired one? If it is USB type try using it with the other chargers and see what your results are.

Yes indeed I notice the Sony Power Pack cable is short and thick. The Samsung cable is long and thin. I get much higher charging power using the thick short cable. Maybe I need go shop for a proper longer/thicker cable.

I've certainly found the USB cable makes a big difference to the charging speed. I got a couple of 2m cables off Ebay and they're hopelessly slow, but the stock Samsung cable is fast. I just wish it was a bit longer!
I have the same issue
I have the Sprint Mega. Not refurbished and original factory state but I have horrific charge/discharge issues. Right now, my phone just got to 100% charge which I then unplugged the charge cable. Within 5 mins, I went from 100% to 96% and it is losing battery even quicker.
VeEuzUKY: It's been a while but do you still have this phone? Any updates? I should prob invest in a thicker USB cable like you've describe. It has the most charge rate.
I got my mega 6.3 last week. Since then it has said 100% charged... even when charging or dead. So I got a new battery thinking it was the battery but its obviously not and im not sure what it is that could be the problem. Im not sure if its crucial for my phone, if it can be fixed easily and cheaply, or if I need to return my phone to the place I bought it from.
I just got the phone today, and for the most part the phone has been great.
I got it on 11b, and was able to downgrade it to 10c. I rooted it with Stump, and used Bump! to install TWRP. I used Xposed framework, G3 Tweaksbox, Titanium Backup (a lot of bloatware disabled), and root explorer.
The phone is lag-free after some tweaks and all.
Though, one thing that has been bothering me is the overheating.
At first I did disabled Thermal Daemon Mitigation, then realize this was the reason for most of it.
Next, I reenabled it and it fixed the very hot phone (which caused my phone to constantly turn on and off. Like, it would unlock and turn off.)
I let the phone sit, and it got cold. I placed the battery back in, and used it like normal.
I plugged the charger that came in with the phone. When it was connected via PC, the wire did not heat up. I plugged it into the wall charger, and into the outlet. The adapter became VERY hot, as well as the ends of the cable.
I used my old charger (one I bought on Amazon, it's a pretty new and very good charger) and a different wall adapter. The wire and adapter are fine, yet the phone still runs warm.
I disabled most of the bloatware, and the only app I have that takes up a lot of up power and resources (though it's nothing to the G3) is Facebook.
Due to process of elimination, it cannot be the charger. So it's obviously the phone.
I knew it was prone to overheating (more than over flagship devices (apparently) at least), but is it supposed to run this warm when on WiFi? Seems abnormal.
It could be that I am not used to it.
TL;DR
The original phone charger runs VERY hot at the tips to the cable and the charging block does at well. I changed them.
(Even when not on the charger.)
The phone itself is generally warm, far more than most phones I've used.
Is my device defective, or is this normal for this device?
Some heat worse than others. Mine gets quite warm while playing Ingress, for example. The heatsink on the G3's is reportedly horrible generally.
It might be possible to disassemble the phone and apply heat sink paste or something to help dissipate heat better, but I am not sure.
Also, yours might really be defective.

You may have damaged something. Doing this allows the thermal sensors to reach 120 degrees Celsius and then the phone is supposed to shut down.
Mine gets warm, not hot, when charging. I do notice it charges fast, faster than other phones I've had, when connected to the outlet charger. The outlet charger I have is bigger than most that I've seen. I'm wondering if it's the fast charging that causes this?
Does anyone else think the G3 chargers faster when using a wall outlet than most other phones?

I don't know what happened, but the phone is fine now.
It gets warm, but I am going to ahead that is normal for this phone.
As for the outlet charger, I just use the USB cable to my PC and I haven't had any issues.
The first day I had it, it took forever to charge (didn't use the LG cable), but now it charges pretty fast and only gets warm!

That's good. Mine gets warm just charging, not hot as I stated. However, if plugged in and I start playing a game or something, then it gets warmer, but not scalding hot. Of course, that's if I'm playing the game for a long time.
I still think the wall charger must be charge it quicker than on the PC, but yes, I've also noticed hooked up to the PC it charges PDQ. I like that!

Had SkyDragon's custom kernel since I basically got the phone, so yeah.
It was thermal daemon being changed, reverting it fixed most of the issues.
The phone just gets warm, I guess.
Seems normal.
