battery overheating

hi guys..just got SGS2 and I have battery overheating problem, I saw a lot links on google with that problem but could not find solution...is there a soultion for this kinda big problem?

It's not the battery..it's the phone and processor overheating, working nonstop due to constant updates of apps, searching for signal and so on. It's like a car revved up on traffic.
Try to find out what's actually running on the phone, you can start by reading battery related threads.

thank you for your quick tip...for example, all apps are down, i only use browser and after 10 min it is so hot...so there is no any custom rom here that reduces this heat a bit??? seems little bit to much

There has to be something running in the background..could be apps updating, or phone searching for signal(especially if you have wrong modem installed).
I personally check Every apps I installed, and make sure they don't do auto update. Quick check, try to turn off background data, and then auto sync (both in setting). See what happened.

To my experience
Using wifi with low signal can caused significant battery heat.

Are you using the phone while it's charging, that tends to heat it also

Relax, there is nothing wrong with your phone. If you play a game or browse flash powered sites, you can cook eggs on the back of your S2! Talk about multitasking phones, who else can cook you breakfast?
Personally, I reduced drastically the heat/power consumption by rooting the phone and removing over 60mb of crap. Now I run at 160mb of memory for services and my battery life easily doubled. It still heats when I charge it for a while... On my old Palm Pre2, after 2hrs of usage my battery was completely drained with similar heat issues.

Off-Topic:
That is a lot of wakelocks that maps is giving you there man!

Thanks, never thought about it... How do I fix this?

First: HOW HOT is Your hot ? (for an Eskimo 15 °C is already very hot)
Second: Leave it as it is. EVERY ELECTRICAL DEVICE gets hot when used. The more the hotter.
E.g. Laptop core i7 CPUs are designed for max. Heat of 105° C and my Vaio runs at 85°C when CPU is at 100%.

I'm gunna guess........ Latitude? Do you have this enabled? It depends on what you are trying to do, about 25% battery in 5 hours running time isn't too bad or anything, just all of those waking events add up. Also it could be that you are out and about and that your WiFi is constantly searching, that would be my other guess. But maps has already admitted to eating 21% of your charge on your third screenshot

Ya, latitude is on.

galaxy note heating issue

Dont u feel gets overheated while playing games or charging or while hardcore using ur fone..Is der ny solution to this problem? I cant even make calls as the phone heats up my ear too much

It's normal that the phone gets warm when playing games or using it much...
Try find out what the temp of the phone is when it's hot...

51°C as told by elixir.is it normal?

It gets particularly hot when I browse the Internet nonstop for about 10 minutes.

I have been around 51°C, but normally around 47°C when my phone is working hard. So guess it's kinda normal...
/CK

yep, mine gets really hot when I run the WAZE app on it as well as if i'm listening to streaming music on it. Unless i hold it up to the A/C vents in the car, it will get too hot for me to put it up to my ear to make/receive a call.

I also have problems when I use it as a navigation tool on my motorbike. The waterproof sat nav case prevents circulation and after 20 mins I get a message that battery charging stopped because of to much heat. Figuring now out how to add some vent with a fan/vent.

Pleasse guys take care of your note don't let it overheated.. overheating may result in a failure of your motherboard and phone will never boot up

And with current consumer Law Samsung will have an obligation to either repair or replace the device.
use your phone as normal.

Yes and the only solution it is undervolting the gpu and cpu with some app like tegrak, setcpu or cpu master

I swtiched from LR1 modem to LPT today and I swear my phone is running cooler. I've used it the same as I do everyday and I can really tell it is cooler. Although LPT is slower in speed test for me I think I will keep it for awhile.

Post battery temps here.

While charging my galaxy s3 on Verizon can get little warm (103°f while being used) and I just wondered what everyone else was running at. So if you have a battery temp app or widget feel free to post your max temps and averages here.

Hmm 103f is what 39 deg Celsius? Seems quite normal to me for a battery while using, mine also gets warm if i use it for a while webbrowsing and stuff (i have mine on max brightness too). Also if you have a tight fitting/closed case those can raise temps up a bit (obviously)
-my 2 cents.

Yeah I have a case on order right now. When I am just browsing the Web the phone doesn't get too warm, but if I am browsing the Web and charging it can get hot.

120 is considered hot and I'm not not really getting close to that. Thanks.

I think galaxy s3 doesn't read the temperature right. I feel the phone very hot in my hands that is already uncomfortable and it says 99.0°F

I've seen mine at 105F earlier this week. And yes, even when it only reads in the mid to upper 90s, it's uncomfortable to hold down on the lower half of the back of the phone.

111 is the most that I have seen.

Battery life sucks

2 hours on the phone did this to my battery. Screen time was 48 mins. Screen was off on call using BT. Phone was red hot after call

It is something you installed or something on your setting up the phone.
this phone battery is amazing , trust me it is.
I get screen on times , unthinkable to my previous phones with brightness way way higher
so.. just try to figure out what is eating your batt and why.
edit:
then again you didnt start your battery log with 100% batt
and your drain was due to a very phone cal (?) With screen off, but your network signal suck really bad, maybe is from there ? But even with low coverage I find it hard to imagine that drain.
But then again.. never had low coverage ..

Yeah I can assure you it's something in your settings that is giving you poor life. You didn't give much description of what they are so it's tough for me to help you with what to fix, or how much knowledge you already have. I recommend BetterBatteryStats and Battery Mix for starters.

Install BBS (Better Battery Stats) and find the rogue application that is causing battery drain.
Battery life for me is amazing. I get close to 28-30 hours with mid - heavy usage.

Your signal during this two hour call was awful. Keeping a connection while not using the phone is a battery sucker in these conditions. I imagine it is much more so when you are actually on the phone. I'd suspect that as the culprit, as the radio has to be pumped up to the max constantly, instead of every minute or so.

I had a note 2 on same network and never saw this kind of drain. I think this qualcomm chip is ****. In my settings my cpu was at 2.27ghz for 1 hour 43 mins! Why was my cpu maxed out while making a simple call.?

[Q] Sprint LS980 Heat issue - anyone else?

Noticed that my G2 was getting pretty warm this morning while web browsing. After that I ran Antutu and it was really warm. Just to see how warm it was getting it installed System Tuner and left it open while running Antutu again. As soon as it was finished I kicked over into System Tuner to find under CPU the temp was 168.8F. Playing Angry Birds SW it's in the mid 140s, browsing was 120ish. That seems abnormally hot to me. It's at 109.4F right now with only ST open, nothing else and it's been sitting off for 20 minutes. Thinking about returning it for a replacement.
G2 is completely stock, not rooted, very few apps installed. Only syncing is gmail, contacts, chrome & app data. Wifi on and connected, strong tower signal. No case on the phone.
I've read through a few threads in various places discussing the G2 getting hot but I've yet to see anyone post temps like this. I do realize that Antutu is a tool and doesn't reflect everyday real world use, but it's hitting high temperature in games too.
Thoughts, opinions?
Edit: Ran Antutu again and checked battery temp with cpu z, was at 102.7

Updated with a couple pics

way too hot, you probably have a process stuck in the background. did it go away after a reboot?

I've rebooted several times through the day and it hasn't made a difference. Went up to 131F just now running Tapatalk. I haven't found anything stuck in the background either. This thing heats up just browsing.

I've noticed my G2 feeling warm also. After Web browsing for a few minutes, the CPU temp is 120 according to System Tuner. It was warmer earlier today, but didn't have a chance to check the temp.
