Battery overheating issue? Read

I'm posting this for informative purposes. This is not to ***** about anything or prove anyone wrong. These are simply my findings and my conclusion. I was a sales person for wireless carriers for 8 years and saw this stuff a lot and I would stress test phones before swapping because I hated giving people refurbished crap for them to come back and complain about the same overheat issue. This experience led me to think before doing a device swap.
my G2x battery got hot from day one. From my monitoring I noticed the following.
1. The phone itself was not really hot. Just general radiation from the immediate battery area and it cooled off quickly after battery removal while battery would stay hot for a good 15-20 minutes.
2. Battery temp would hit 106 degrees.
3. Battery life just plain sucked. Charging it 2 to 3 times a day on light use.
T-mobile replaced my battery and after one full day of on and off abuse running 6 quadrants in a row at Max overclock amongst other things and with a thick non breathable case in the back the temp never got over 99 degrees. Prior to swap just reading and posting on xda would spike temps and that was with no case.
So before you decide to do anything pay close attention to what exactly is getting hot. Is the actual device hot or is it just the battery. Is the device a tad warmer simply due to the battery being too hot? Get a battery monitor installed to see the temp. Check your settings such as overclocking undervoltage etc.
T-Mobile just wanted to swap everything but since my phone was not hot and I had a good screen and never a boot or reboot issue even before root and bloat installed etc so I didn't want to take a chance and get a **** device. They also told me it was OK that k needed to charge it 3 times a day. I said with triple the usage on my G2 I almost never needed to charge it at all mid day. While each device varies, one third the battery life on one third the usage is simply not right no matter how you look at it.
So I say pay attention to detail before returning your device especially if your device is a good one because it would suck to get a **** device in exchange for your good one just because of a battery.
EDIT. I do want to add that my battery has spiked to 103.8 degrees while basically doing CPU intensive stuff While charging the entire time. When not on the charger it did not spike as high. After a short time after charge hit 100% it dropped over 1.5 degrees pretty quickly.

The fact that you wrote "a lot" instead of "alot" showed me your post was worth reading.

The fact that you wrote that leads me to believe you miss a lot of really important information because someone wrote "alot" as opposed to "a lot". Someone who writes "alot" isn't worth your time or energy?

(FIXED) G2x gets flipping hot sometimes......

Woah is me. My g2x gets hot. So does my mt4g my g2 and anyone else's phone I use. I started to wonder why.....its the way I'm holding it. Yes, simply that. Oh lets not forget after a nice full wipe and everything is installing over again that taxes the processor causing it to get hotter than normal. Oh it gets hot sitting in my pocket doing nothing when it's really hot outside.
Anyone here ever pay attention to when it gets hot and actually wonder why it does?
ITS ALL WONKY!!!

Morfic has a good post somewhere about this. If I recall he made mention that the Tegra 2 can bake a cake under certain conditions (I believe primarily when OC). What kernel are you using?

edit: nvm...

What I'm saying is its general body heat. Our bodies are average of 98.6 degrees. So holding it.in your hand alone will warm up the device.
Think of holding a glass of milk firmly in your hand for a while and see how long it stays cold compared to letting it sit on the table.
In some cases I think it is the phone but I would say 90% or more its the user not the device being a defect.

Yea. I dunno every device I had gets hot under the collar with heavy usage. I think people are nitpicking something. Go to a t-mobile store and abusive every device there and hold it in the same spot the same way and run the same sstuff. .. ill bet in most cases you will have the same results.

My phone only gets hot on the charger, but often says please remove power cord cause "yo ****'s too hot"

This post is completely false. Body heat? Come on.....If this logic were true then why have I picked the phone up off my cocktail table hours after not being used only to feel the phone much hotter than the surface it's sitting on in a air conditioned house? These processors run MUCH hotter than a body temp could ever reach and they were designed to withstand these temperatures. This is what CPU's do when you tax them, they get hot. If you still want to believe this bogus logic then I propose you open a HD game, set it on your cocktail table and only touch the phone with on of your fingers. Play it for about 15 minutes, pick your phone up and tell me if it's hot.
Last time I checked, my laptops CPU/GPU isn't touching anything but still gets hot.

Ok hold your phone by finger tips in the corners and tax the processor and then let it cool down and holdbit firmly from behind and do the same thing and see how much faster it gets hot.
This phone sitting on a table does not get hot at all. In my pocket when its 100 degrees outside does get hot......while doing nothing more than standby.
Its not BS. Yea these processors get hot on their own but I'm making a point that if the back of the phone has body heat covering it, it will get hot or at the least warmer than normal just because of that.
ITS ALL WONKY!!!

I live in an area where it is as hot (soon to be much hotter) as body temperature and my phone does not get noticeably hot unless I am really taxing it. But as far as exceeding design limits of CPUs I would have to be significantly overclocking it and taxing it at the same time.

This is your opinion unless you have the data to prove it. I have had phones get hot without touching them so I'm not believing this and quite frankly not a lot of people are. I asked you a question earlier. Why does my laptop and desktop CPU'S get hot when I never come in contact with them?
Sent from my HTC Sensation 4G using XDA App

In my opinion the thing that makes the phone warm up mostly is the cell radio. Download a 30mb file ( not on wifi) , turn off the screen, and watch how warm it gets. Also watch the large battery hit.
And every smart phone I know will get hot on a demanding game..

My phone only gets hot near the camera when I bootloop.
It barely gets warm when playing a 3D game like Galaxy on Fire 2 or RPTide (or whatever).
I download CM roms (98mb) over cellular EVERY day and the phone feels cool to the touch.

you are comparing a computer to a phone.
i understand your point, anything being run hard will get hot.
im just saying tho, my battery temp has reached 100 degrees just being outside and not used. its reached 100 when i hold it in my hand covering the back a lot even doing simple tasks. when i hold it without the back totally covered from my hand, it does not get as hot when taxing it more. when my speck case is on it does not get as hot if im holding it fully in the back.

Fastest way to charge?

I know Samsung limits the charging on the infuse but is there a certain charger that is faster than the default?

I heard if you plug it in and hold it in your left hand, stand on your right leg, and sing the Macarena, it charges much faster

TRUE! move your hips harder to gain faster charge.

Sweet!! Cant wait to try!!

U need to buy a rapid AC USB adapter
I have a rapid car charger and it works faster than my stock AC one. In your local radioshack they have a rapid charger made by enercell that will do the trick, but its designed for the iPhone and includes the apple sync cable.

I used to use 30yr old single malt.but my wife would yell at me when I did.

Lets get fancy and go with some courvoisier...

I put mine near my laptop fan output area. The heat helps charge it fast.

you should put it on a pan on a stove at medium high. will be charged with in about 20 to 30 mins.
salt lightly.

Um microwaves do it the best

Don't forget the pepper and chilli powder, more spice, more bang for your buck

What you want to do is plug it in (using your iphone charger) while holding it in your left hand, then stand on your right leg, then sing the Macarena, while moving your hips around. Then, unplug it, and leave it in a cup of water on your night table (vodka, tequila, 30 year old malt liquor, or courvoisier will work as well). After an hour or so, place it near your laptop fan output area (the heat helps to charge it faster at this point). After about 15 minutes, put it on a pan on your stove at medium high for about 20 to 30 minutes. You can salt lightly (for added charge, add some pepper and chilli powder). At this point, microwave on high for about 2 minutes. Your phone should be fully charged (and then some) by this point!
I actually heard this from my friend's mom's cousin's neice's friend's uncle's cat, who visits this thread quite often!

Overheating?

Does any one else's Charge seem to get abnormally hot while charging? Like hot to the point where it's uncomfortable to put in my pocket after charging. Wondering if I should try and get the phone replaced before it fries itself or if it's just normal. Thanks!

Mine does it a lot, and its actually getting to the point where it wont charge my battery completely. Charged all last night, battery says 100%, but when I take it off the charger, its on 49%. And it died on 12%. Im taking it to VZW tomorrow to see if they can switch out the battery.

Verizon should replace the overheating phones. Mine overheated so badly that an error message popped up and said the phone could not charge because it was too hot.....something like that. I brought it to Verizon and they swapped it out no problem.

I wonder how many times they can swap out. Because mine overheats when it charges, and sometimes when itaint charging at all.
Sent from my SCH-I510 using XDA Premium App

definitely not normal. Mine charges off of a 2amp charger in under an hour from 10 to 100 percent without getting very hot. Make sure you change out the charger too, the phone might not be the only problem. If there is a partial short it could be causing it.

If it's doing it with the factory charger, yes, it's a problem. If you have an aftermarket charger (or battery), it's most likely that. These phones are a bit touchier than they ought to be about where they accept their power from.

Mine seems to get pretty hot as well. Lets hope that we can pull a fascinate and use the warranty to get the sgs2.

indeed
my charge is overheating as well. there are 2 instances when it overheats. while Charging and downloading a huge file from internet or the app that uses internet/data.
I have tried diff battery did not help. I assume everyones phone is like that. Charge has a overheating problems.
IF you are not agree with me try to torrent on the phone for 20min. Just for testing sake and prove me wrong.(I dont torrent but it is a perfect example)

I had the same thing on my original Charge when it shipped to me. Along with the heat issue, my phone was dying way faster than it should considering my setup.
I went to a VZW corp store and they switched me out with a new battery as part of the manufacturer's warranty program.
The new battery didn't overheat anymore and my battery lasted twice as long.
Either way, you have nothing to lose.

big red is shipping me a replacement today...hopefully its a good one!

As always, if you are having heat problems I recommend underclocking/volting to 800mhz. Last time I did that it solved ALL my heat problems completely! It would only get ever so slightly warm when watching Netflix(the most data and system intensive app I know of). Never hot though.

One S Overheating problem?

I woke up in the middle of the night (4am.) because my phone pretty much burned me and scared the hell out of me while it was charging. The phone was there with a black screen and heated a little over 120 degrees f (measured by a meat thermometer ).
When I pressed the lock button to unlock it, it turned on (I left it charging on) and had less than 50% of battery left. As i pressed the lock button again, the phone rebooted two more times until it let me turn it off.
Anyone know what's wrong and should I contact htc or costco from which I bought it from?

Do you use the charger / usb cable given by HTC ?
Because one time, I tried to charge my phone with another usb cable and my phone was also hot ! (But I don't think like you wow !)

Oh, I'm not the only one then, nice
Mine has gotten hot as well, but that is usually while I use it, not when it's just laying in my bed

My wife always gives me a hard time for sleeping with my phone, lol, it's on our lamp table next to our bed, but since I don't like leaving the phone on a hard surface, it's usually next to me on our bed, LOL.
Mines was overheating a bit when charging with an extended second party charger, but once I started using the HTC charger that came with the phone, it was fine. Also seemed to charge faster with the stock charger, maybe it's a figment of my imagination, who knows.

My phone heated up crazy mad when I watched a movie through the mhl adapter and since the phone is some kind of metal, therefore a perfect conductor, the whole phone was painfully hot to touch. Scared me ****less I've had a lot of android phones and this is the first time . I didn't want to chance it and exchanged it in store still within my 15 day exchange period whew. Anybody know what woulda caused it to overheat like an oven?

mines heats up too. is this every or just some units?
it heats up when playing games or surfing the web.

Mine heats up as well it's all phones.
I had this problem with my Amaze/etc.
Replacement will be the same so don't bother.

Proven to be wrong

The amperage of the adapter doesn't matter, as the phone will only draw as much current as it needs, and no more.
I use the charger for my HP Touchpad with all kinds of phones, and it's rated for 5V 2.0amps.

Mine stays at 105 degrees when I'm doing any gpc or 4g stuff on it when its not charging or anything is that normal ?
Sent from my HTC VLE_U using XDA

I think of it this way... I have a dual core 1.5ghz processor running inside a super thin aluminum case. I expect it to get hot, and even hotter when charging or under load. As long as I'm in warranty and the phone still works fine, I'm not going to worry about it.
Now, if it's causing SOD problems, that's different.

Just some units have a faulty battery or loose cable ever since I exchanged my faulty heating up one no heating at all

I'd be careful where you leave your phone charging. The daughter of family friends left her phone unattended charging on the bed and unfortunately set the bed on fire. This went on to pretty much destroy the house. NOT an urban myth either. Laptops and anything that charges need a little caution.
For those sleeping with their phones - stop it! The phone is big enough to sleep on its own

My overheating is gone I believe. It was there the first 24 hours. I guess because it was the first time it was being used.
After I fully charged it off, it doesnt get as hot anymore.

same here--

That was a one time thing hasn't happen agian.
