Hi guys,
I used GPS for first time with my new SGS2. I was surprised how phone was hot. I had SGS but I never had any problem. GPS program is Sygic, I used same car charger, which I used for SGS. I drove home maybe 10min and phone was realy very hot, the screen also,back of the phone. Do you have same problem or do you think my phone is faulty?
Mine after 30 min surfing the internet is very hot (next to the camera and screen on top). Also i am worried about that...

Yes this I have same, but it is still OK compare to GPS and charging.
GPS + charge is always a hit or miss. My SGS was a little better, but my HTC Touch Pro 2 got blazing hot. All depends on the device, I'm more worried about the long term effects of such temperatures to the camera, which is in very close proximity.
I noticed when using sygic with gps that the battery continues to drain even when using the car charger.

There's a good answer to that. I had a cheap generic USB car charger and noticed it drained quicker than it charged. The reason is down to a pin on the USB connector. Your phone will only charge at rate it would if plugged to a PC. Buy a genuine Samsung car charger (about a tenner) and it uses fast/full charge. I think they remove/link pins which tell it how to charge. I also found it doesn't get as hot with a genuine charger

Maby I can confirm this ...
Was on a 1 hour trip using navigation.
My screen brightness was about 20%
Did not get warm and charged +6%
I use a standard Samsung charger.

True is, I have non original car charger, but I bought some cheap one. Never charge my SGS, just kept at the same level. So I am going to buy original from Samsung.
When ur using anything Radio and/or charging for a long time its gonna get hot, by hot i mean burning hot. On my sgs, nexus one, cliq when i am on long phone calls (>30min) and charging they all get hot, and get hot when using gps even when not charging. GPS on SGS is a hit or a miss though, barely use that phone for gps
Don't listen to peopel telling you it's the charge that is causing the phone to heat up.
thats just nonsense.
Its the 1.2ghz cpu.. and the close tight body of the phone.
I had the Atrix, and after 10-15 of heavy usage or just gps, the bottom portion near the sim area would be hot to the touch.
Think about it this way.
Why do laptops even in such tight close spaces have some fan going? because things get hot.
Stop the fan on a laptop and let the heatsink just do the work and it will burn u.
Its just the thep hone despensing the heat.
I personally dont' think phones with 1.2ghz processors should be made so small, and not have some time of active cooling.
Seriously even if my NAS Server with a marvell 1.2ghz CPU has some type of cooling fan!
this is just ridiculous
Mine also tends to heat up. I then always take off the case and try to get it cooled down somehow. But i've experienced it myself: half an hour gps+navigation=processor hot as hell and battery drained down from 85% to 15%...hope the latest firmware update fixes this...and btw: heat is not very good for any kind of battery. It makes them drain faster afaik!

Well I have a 1mA charger which I used with my HTC Desire to charge it during driving and navigating. It worked well with my HTC Desire (the HTC Desire also needs a pin connection, otherwise it won't charge fast enough during navigating) but the same charger did not work very well with the SGS2. Yesterday during navigation the battery level dropped slowly... Even though I used the same charger as I used with my HTC Desire.

Yeah,u are right~
The competion of thickness between samsung and apple,or other android os manufucture like S.E has crushed samsung's mind.To elicit applause,the Korean giant just sacrificed the stability to make a both thin and powerful phone.
It's hard to say the choice is wise or not.But we can already find this company is becoming upset due to the pressure from the opponents.
Did Lincoln to London (135miles), phone in cradle with brightness 100%, CamerAlert and Google Navigation running, powered via USB converter in the car.
Battery went up about 1% every 20 minutes.
Phone out of cradle at the end wasn't hot to touch unlike every other phone I've had.

IT seems that samsung has a quality variation. Did you use a brand charger or an aftermarket one?
Ok guys i am quite worried now. I played game about 10min and the top half of the phone is quite hot again. Do you have same problem or should I take mine back to a shop? I do not think this is normal right?

I use my car dock constantly with my X. I have my car charger connected to it so I don't kill my battery from Pandora. So today I used my gps in conjunction with Pandora. After about 20 minutes I noticed my battery indicator had dropped. I looked close and it wasn't charging anymore. I unplugged and plugged in each connection (cigarette lighter, back of dock, phone in dock). No dice. The phone did recognize I was unplugging it, though, as it reminded me to unplug my charger to conserve energy. I also tried to charge the phone with just the car charger alone instead of running though the dock. Still no dice. I got to my destination and took my phone inside with me. It was SUPER hot, but still running. I rebooted the phone and it was able to charge in my car again. I listened to Pandora without gps to get lunch. It indicated the phone was charging, but the battery % dropped a bit. The phone was no longer hot. It is now charging my phone without running Pandora or the gps. I took a trip using gps and pandora in conjunction without losing power, but also didn't gain a charge while in the dock. Could the heat have caused Android to force the charge to stop, or is the charger a piece?
I noticed the same the battery is overheating if possible put an ac vent on it. I've had this happen with my tp2 as well as my X. Sucks get to your destination with a dead phone.

Hi..I also get battery drain, but no where near as bad as that.. Maybe 2% per hour.. I've had a couple of chargers off ebay and one is better than the other, so it could be that your charger is the problem rather than the phone?

Mines has started charging properly now with sat navigation on...
Only difference is I'm no longer using Google which, as you'll know, uses data which is what eats the battery (and your allowance)
it also depends on which charger you on using. I think the original X10 charger is .5A (500mA) charger. If you get a higher rated charger, you should be able to charge the phone faster even with the drain.
The standard HTC chargers are rated 1A (1000mA), pretty cheap online
I've found that when my x10 gets too hot while using copilot it stops charging. I just turn the screen off for a bit and it cools down again!

Yes that's normal, but you said it gets very hot, and again, read my first reply to your post and tell me what you see, then we can tell you if your heating is normal or not.
make sure you turn off WiFi when you are charging the battery on your SNS
else it heats up really really fast and hot
that was the same on the SGS

It seems common behavior on the Nexus. My NS got up to 105° F last night (to be fair, it was under my pillow). I've simply taken to turning it off when I charge at night, but seeing as my NS is a glorified PMP (and therefore I don't have to worry about texts or other notifications on it), you might feel differently about simply turning it off.
Sent from my Nexus S using XDA App
It's interesting to note that the adapter for the Nexus S actually charges at(and I'm sure I'm getting my terminology wrong, sorry electricity guys!) .7AMP vs the 1AMP that other smart phones charges at such as the Nexus One.
This might account for the seemingly longer charge times we've had reported, and why you might be seeing increased heating from using a third-party more generalized charger. Whether or not there's any truth to the idea that it may cause permanent damage to your device, I don't know. I would greatly appreciate it if someone more knowledgable about this kind of thing would post, as I'm considering buying a second charger/car charger. In any which case, I personally take what Best Buy/T-Mobile/anyone's first level support tell me with a great big grain of salt.
google maps heating phone up
I just had a similar experience with my Nexus S getting really warm while using Google Maps this morning. I usually use Google Maps in Car Mode with traffic overlayed as I drive to and from work (~30-40 min. drive). This morning I noticed the phone got really warm by the end of my commute, which did not happen the previous 3 or 4 times I have used Maps in this same fashion. I will take nxt's advice and check the temperature on the phone next time it heats up again. Does anyone know what is a "safe" upper temperature limit for the phone or battery? I've read that higher temperatures are detrimental to the life of a lithium battery.
Other than this one time, I have not experienced any other high temperature issues with my Nexus S in the ~1 week that I've had it.
Thanks ahead of time for any help/advice. This is my very first smartphone and I am eagerly trying to absorb as much information as I can about it so I can determine what is normal/abnormal behavior. I am loving my Nexus S so far!
I don't think third party chargers are to blame. In fact, I'd go as far as to say the opposite is true. I read that the shorter data pins on the official charger cause the device to enter a faster charging state, as compared to the usb cable or third party chargers.
I've yet to feel my nexus s get warm at all... during charging w/ wifi on. Using samsung wall charger, using LG wall charger, using computers w/usb cable.
My NS gets hotter to the touch than my Vibrant ever did, but when I check the battery temperature it is never as high as my Vibrant used to get.
When charging in the car and running Navigation + streaming music the Vibrant would hit almost 125F whereas my NS tops out at 110F.

it depends on the usage
when i download TONS of stuff via 3G or WiFi it heats up a lot, only if i have it plugged in to the charger, else it does not heat up
However! if you check carefully, or better yet, if you take out the back cover
you will notice it is not the battery that is hot, but the area beneath the SIM card that is hot, which points to be the CPU

I see, thanks. Will keep in mind.
FWIW, I have been charging my Nexus S with the Nexus One charger (1 amp) since day 1 - I can't stand how short the stock charging cable and wall adapter were. I haven't had any unusual temperature spikes when charging at all. I don't even really notice it getting warm under heavy load - unlike the Nexus One with the aluminum casing that conducted heat very well. Edit: I also leave WiFi on with a No Sleep policy when I am at home and I've not encountered any warming issues either.
I would be careful if I ware you.. high heat is dangerous for the battery, it might swallow and even a leak if you will keep using your device constantly at high temperatures.
I Have never had any problems with heat and I have been using it a lot.
btw, I use stock rom..
Strange Issue!!
when my phone is low on battery and i try to charge it (with the original ac charger or the usb); sometimes (almost half the times) the phone instead of charging .... DISCHARGES!!
i have tried all possible fixes. tried the battery calibration apps also. but it gets ok for a day and then back.
i can only charge my phone while its switched off!
Details:
1. on stock TW4
2. 3 pages on home
3. total widgets= 6 ( advanced task killer; digital clock; 2- circle launcher; quick battery; weather)
4. i kill all tasks always before charging!
WHAT AM I DOING WRONG? BTW I HAVE TRIED TO REMOVE ALL WIDGETS AND CHARGE ALSO! NO LUCK!

It sound like you might have a faulty charger, have you tried charging from your notebook, it`s a bit slower at 400mah compared to 650mah for the mains charger.

Yes, as a matter of fact, right now i am trying to charge through USB with the same drainage.
Switch the phone off for a while!... let the sucker charge.
And the problem is not always!
this is normal, already been posted. the charger is limited to 650 mA on wall power, and 450 mA on USB power. so it is easily possible to pull more power than is going into the device, say if you are gaming or pushing the device hard with navigation or similar.
next time this happens, turn off the screen for 10 minutes as a test, then come back, and see if the charge increased at all. it likely will increase.

Edit: i also have read in many places that using task killer actually cause more harm than good bcoz it disturbs the proper sequece of how android shuts down an app or process..and cleans up the memory..this will result some of the apps or process to stay awake or come awake again when it sould be sleeping...

I once had this problem..after charging for 6 hours battery was only at 60% and phone was hot..found out that although the screen was off..the phone was wide awake all the time. For me the issue was the wifi manager was somehow awake and consuming power..hence phone was hot and battery drain while charging. Check your battery usage graph and see if your phone is awake when it should not be..and pin down the rouge app or process..
Hope this helps..

That's right,but if the charger was 1000mA like HTC's it would continue to draw those 700mA it needs even while in use.You wouldn't notice any difference at all with it charging while not being used,but when screen is on there is a difference.
They limited charge current to 650 mA in the driver code, so that's why they use a 0.7 A charger. Using a higher output won't help unless someone compiles a new kernel.
I charge the phone until 100%. When unplug, it immediately drops to 85%-90%. On one occassions, it dropped to 40%! What's wrong with it?

I suggest you do a simple trouble shooting...charge your phone to 100% while it is off.
Than unplug, switch on your phone and just leave it for half hour or an hour without doing anything.
Than swith your display on...and go to settings
Select about phone..
Go to battery use and tap on the graph.
It will show you a few horizontal lines.
Make sure your screen on and awake time bars coincide nicely.
While your screen is off your awake bar should be very very minumum... most of the high battery drain casses will have a very short screen on bar but a solid long line of awake time.
This is normally due to some rougue app or process...and you have to narrow it down.
If your graph looks normal..than you could be having a defective battery or in worst case a defective hardware.

I received my Nexus 4 in the mail yesterday and I have been charging it while in the car sometimes. Has anyone experienced the back of their Nexus 4 becoming hot while charging the phone inside a car? I'm using a Griffin Car charger and an HTC USB cord from one of my old phones (I've used the charger and cord for other phones, MyTouch 4G and HTC Sensation 4G, without a problem. When I charge the phone with the LG charger or any other wall charger (inside my house) the back of the phone doesn't seem to get warm. Could it be the USB Cord is the issue? Didn't think that would be a problem but I'll try a different one tomorrow. Just wondering if anyone has had a similar experience.
did you use your phone while charging? i'am thingking about navigation?!
mine gets a bit warm while charging, but not noteable if it is uncovert, and it gets warm while google maps runs, both together makes it quite warm, plus, putting it in a carholder where its back is covert...
but nothing you should worry about, other phones do the same...
You don't need to worry until the battery gets above 60°C. Li-po batteries can be damaged above that. Monitor the temp while charging in the car
My back of phone is hot whenever I'm charging! Lol :thumbup:

No, I wasn't using navigation but I was playing music via the music player.

What app do you use to monitor battery temperature? I've never really paid attention to the battery temperature before, this is also the first device I've had without a removalable battery.

After further review, I have realized it just isn't warm when I'm charging it in my car. It also happens when I'm using it (sending texts, phone calls and browsing) and when its charging in the house. The temperature will get to around 51C (used the system tuner app). Has anyone else experienced the back of their Nexus 4 getting warm during normal use and charging? Just trying to figure out if this is a defect or it's normal for the device.

It's normal if you're using stock voltage. I undervolted my Nexus 4 and it rarely gets above 35°C off of the charger.

How do you "undervolt" it? I just picked the phone up off the charger (after not using it for ten minutes) and the battery temperature was 36C. This was using the charger that came with the phone.

You have to unlock the bootloader, root, install a kernel that supports undervolting and lower the voltage that the CPU uses. You see, each chip is different. When creating the stock kernel they figure out what voltage range all phones will work on, then add some to be safe. The higher voltage = more heat. You experiment a little to see how low you can go and have a stable device and leave the settings. It's easier than it sounds.

I was having the same issue and I never thought of lowering the voltage. The thing runs like butter anyway, so it won't hurt for it to slow down just a tad so it doesn't get to 50C.
Thanks.
