I've had my thunderbolt for awhile now and ive been noticing how hot it gets when streaming movies I downloaded a battery temp widget and at ruined it gets above 107 wstreaming movies or downloading, I do live in Atlanta and it is on the high 90,s but I didn't seem to b noticing this on my incredible. I'm rooted and have been running diffrent time running gingeritis v1.0 now
If you're that worried, quit overclocking. Also, not all the heat is from the cpu; some is given off by the internals related to the antenna, but shouldn't be a problem unless it's used excessively over a long period of time. I've had it overheat and reset from doing a large download over LTE for a few hours.
Not really concerned more curious to wether everyone else is seeing fast heat up to
It's almost 100 degrees out, you are streaming movies and OC'd, and you are wondering if the phone getting hot in conditions like this is abnormal

You have to remember that most of that heat is generated because of the reactions within the battery to supply power to the phone. So the more draw you put on the battery the hotter it's going to get. Lithium batteries are notorious for running high temps when being charged/discharged. It's part of the price you pay to have more capacity is a smaller space.
I flown RC heli's for years, so I'm very familiar with how lithium batteries react. They pack alot of power in minimum space, but they can be dangerous is certain situations (that's why cars like the Prius still do not use them in production because of the fire risk).
Just a bit of info to think about.
There's a good thread on xda that's has documented on several test that LTE is the cause of the overheating. The test was done on stock ruu with no OC. Of course being Oc'd doesn't help your case, but I've noticed LTE in weak areas can raise battery temperature up to 107 degrees Fahrenheit without streaming video or having any rogue applications running. I've also reduced cpu speed to 744 mhz with no luck. Hopefully new RUU releases will address this problem.
I'll post the thread when I get a chance.

I don't believe that is the cause at all, as I have 4G, and use it, where I live all day, and OC to 1.4, I have never had overheating problems at all. He was outside in almost 100 degree weather, streaming movies, there isn't a fan cooling the phone, that temperature is normal.
I'm outside during the week in 80-85 degree weather, streaming music on a sunny day and my phone gets hotter than normal, because it is working harder than normal.
The OP is downloading or streaming movies in hot weather when it gets hot. 2 data & processor intensive tasks, you can't expect it to stay cool at normal temperature in conditions like that.

That's certainly another factor I didn't consider.
I understand all that I've played with all the processor speeds and observed how of reacts in difrent situations compared to the incredible and even on 3g under all same conditions it heats up at a way faster rate, not saying the reason its overheating isn't my fault nor do I ever let it get past a safe level just wondering
OP, trust me your phone is not "Overheating" at 107. If it gets to 125/130+ then you have a problem but these phones were built to withstand the temps you are seeing.
Basically, don't worry about it.
The biggest thing i have noticed is that when i recharge with the power cord at home, it don't get hot. But when i recharge with a cig adaptor, it runs pretty hot. But on the flipside of that, If i use my wifes cig charger that came with her LG ally, it don't overheat. These phones are drama queens about charging

That may be because of the quality of the chargers you are using. Electrical power is kind of like water. The bigger the pipes the better the flow. If you have a good pipeline, less heat because the battery doesn't have to work so hard pulling the electricity in.
A wall charger (spec'd for your phone) is probably the best choice, you wife's cig charger may just be a bit better quality with thicker gauge wiring.
I know this is a pretty simplified explanation, but hopefully it makes sense.

it's also possible that the Ally requires less power. The Thunderbolt is spec'd for charging at 5V/1A. If the Ally is 5V/800ma, then it would not get as hot when charging the Ally. Out of curiosity, what does the charger spec as voltage/amperage?

Where are you measuring the temp from? Mine gets hot in the car dock too but not overly. I figure google will have tested it. So am not really concerned.
If you want to mitigate the heat while it is charging in the car dock, simply minimise what the phone is doing. ie no nav/gps and screen off. You could for example do this 5 or 10 minutes before your destination and it may be somewhat cooler when you take it out of the dock. Obviously this may not be appropriate as you might need to use it at this point. Just a suggestion though if the heat is a real concern to you.

I am sure is accurate. But I would only get concerned myself, if the phone case itself was alarmingly hot and I feared something was melting or burning. I am not worried about what Temp battery apps or the inbuilt Testing reports. I figure the phone system will shut it self down or reduce load if thresholds are reached.
yeah that's right. But anyway I do not think a temp of 50 celsius is exactly healty for the battery. We do not all live in Alaska and it might get mighty hot in southwest texas or southern Italy... In addiction I think the warmth has something to do with the screen as pretty much EVERY TIME I take the phone off the car dock the screen calibration is all f'd up. I seldom experienced that before but now it is 95% of the times I take it off the car dock. Sometimes even when plugged into the dock.
I love the phone and the dock, and this is maybe the only one glitch I found so far, but is really very annoying when it happens.
If anybody could help I would really appreciate that.
Also, any answer like "put it in front of the AC outlet" to me is pointless. It should not get that hot. period. and owning a Camaro it is not that easy to figure out a good spot to glue the disc on, surely not near an A/C vent...

I don't have the official Nexus One car dock but I have a car dock. Mine is pretty hot after I take it out. GPS on, dimness auto on, screen timeout off, audio to stereo, and charging.
I would say it's not the docks problem but rather its the heavy use of the phone. I've read this is normal on the nexus one since it's got a 1ghz processor. Heavy use = heat.
I've got heat issues in Phoenix but I'm confident it will be fine this summer.
Ironically, i DO live in Alaska, and noted it was a bit warm charging, playing music, and using GPS navigation.

Is there any way to speed up the charging process? a rapid charger? external charger where i can take the battery out and charge it in a charging pod faster then it charges while in the phone?
You may have a defective battery, mine charges as quickly as expected. Note: charging via a computer's USB port is always slower than charging from a wall outlet (though it does top the charge off slightly higher), though this rarely delays charging by more than 30 mins.

I understand your pain. When I had the SGS2 (coming from an iPhone), it took almost a half a day to charge up (exagerating). 30 min charge would only give you a handful of percentage. I am a bit more happy with the charging time of the Skyrocket though. Not amazingly faster, but quite a bit.

Umm.. We talking about battery life here... It's also not "android battery life" (no such thing), it's the samsung skyrocket phone's battery life we are talking about. You can vibrate the hell out of your phone between your legs and run out of juice. But it'll take a long time for it to recharge until you can continue with your vibrating.
As for can't do a whole lot with an iphone: I drain my phone with tower defense games like Sentinel 3. Available for both platforms. Drains battery just the same.
Nobody an iPhone fanboy here (this is xda, is it not?), but then again, I dont drink anyone's kool-aid...

That's why you don't ****ing charge from the computer. Also it is really fast to charge up to around 85%, the next 15% will take much longer due to the way all lithium batteries are made.
Yes, it takes longer to charge up the Skyrocket than it does an iPhone.
Part of this is because the Skyrocket battery is a larger capacity battery than the iPhone battery.
The larger the battery, the longer it takes to charge up.
The bigger your glass of milk, the longer it takes to fill it up.
The larger your cars gas tank, the longer it takes to fuel it up.
Etc.etc.etc.
But in keeping with the thread, I'd like to second the request for any info on fast chargers. We know that USB/computer charges slower than wall outlet chargers (wall-marts). But are there any wall chargers that charge faster than others?
I doubt it i believe the phones hardware only excepts a certain voltage and amperage. So even if the charger was slightly.highrr voltage and or.amperage the phone will only accept.what the hardware allows. You can have an underpowerd charger but to prevent mishaps there designed not to be able to overpower i may be wrong but i believe thats whus up
I've looked around and either most people are confused as to whether they're talking about battery temps or CPU temps or cannot come up with a definitive answer.
I'm looking for an answer on CPU temps and not one of those "I've seen a phone get up to 1000 degrees once and still work" I mean I'd like to know what a phone can consistently(hours at a time) run at without causing damage.
Reason I ask is when I tether my CPU is at 140 F and the Battery is at 109 F. Now I'm not too overly concerned about the battery I'm fairly confident that 109 isn't damaging it. I am concerned about the CPU though as I have no clue when the "danger zone" is tripped temperature wise. If someone could enlighten me it would be appreciated.
When it's gets that hot, I'll remove my battery and let it sit for 20 minutes. Then I'll swap it out for another new battery off the wall charger.

Usually at this point I remove the back cover and place the phone upside down in front of a fan which cools it but I would like to know if this is even necessary....
Higher temperatres for batteries are not good for them at any time, they will speed up the degredation of the battery itself. That being said, it routintely gets 109 degrees in the summer where I live and I rarely have a battery problem, you will noticed a shorter life span on batteries both while they are being used and over several charge and discharge cycles. The battery will naturally heat up while charging, especially using the rapid-charge methods most phones use right now or when charging from a very low charge.
As far as the CPU goes, 140 degrees is about 60 C, most CPU's can tolerate up to around 70-75 C without causing problems. Also, IIRC most boards have a cutoff if the device gets too hot to operate, I know the iPhone does so I would imagine that Android devices do as well.
That leaves it a matter of your own comfort, if it is too hot for you to actully hold onto and use - that I have seen before, in which case the best method for cooling it off is to actually turn the phone off, remove the battery and let it sit at room temperature until the device cools. Using a fan will work but is far less effective. The use of power-saving mode can also help because a good portion of heat in the battery while discharging is due to the CPU and Power Saving mode sets the CPU to favor lower processing speeds, which of course lowers heat. This does assume you're not doing something with your phone that will tax the CPU.

Another thing to keep in mind about batteries and high temperatures is that the negative effect from the high temperature is at it's worst the higher the charge level. So if it's going to be getting hot--it's best to not keep it plugged in constantly.

First of all, all smartphones gets hot while playing games and charging at the same time.
And charging the phone do generate small amount of heat, so do not put it underneath your pillow while charging. (shouldn't be hot to touch though)
If you are not doing anything mention above and the battery is still getting dangerously hot while charging, contact Google customer service (if its from play store) or your carrier.

Did you ever think about that this phone has a quad core processor that throttles at 70 degrees Celsius. That's 158F. Where's the heat going to go? Surely the heat will go somewhere but it will heat up the plastic somewhat.

That will happen no matter what.. enjoy your phone... get new one after year or two.
This guy just likes to troll, don't pay any attention to him. Look at his post history.
For the record, 44C is on the higher side but my M7 regularly hit 48C and had the same battery life it did out of the box a year later. There are varying degrees of battery quality. You'll kill your battery more leaving it to trickle charge all the time than from 44C temps. You'll also kill it faster the more times you charge it to 100% than the temps will.
