hi, I am running cm7 with stock kernel. Just recently my phone has been getting really hot. I checked the temp and its almost 110 degrees. I haven't installed anything recently either.
I can leave the phone sitting there not using it and it'll still be high. Should I install another kernel or do I need to change settings on my phone? I am using extended battery too.
Thanks.

Hmm any case on it? When its charging leave it face down too.
I have no case on it. Will searching for a signal cause the battery to get hot? My cell standby is at 54% and it says time without signal 67%

Mine got real hot after loading the latest CM7, while trying to sync all on 4G. It was smoking hot in my pocket, so I pulled it out, and took the Trident Aegis case off to help it cool down. I looked and noticed it was stuck at 3G but still trying to sync all.
I had to do the time consuming routine to get 4G every time I turn on the data, and my GPS was still not working, so the hot battery sealed the deal... back to BAMF 1.8 till the next CM7 release is ready to test.
I ran into this one time and found that turning off Wifi seemed to do the trick. It seemed as though constant searching for an available Wifi network caused my battery to get hot. This makes sense if you read how tethering causes some phones to get hot as well.
Thanks I guess the searching for a single is the culprit bc it doesn't get hot while charging.

I'm experiencing the same thing and the exact cause is a mystery to me. The battery definitely gets hotter than it did with BAMF stripped 2.1, yet I get much better battery life than I ever did with sense. This completely defies logic since the two things that will make a li-poly battery warm are a high C draw or charge, but a high C draw should correlate to poor battery life yet it doesn't. I'm starting to wonder if something other than the battery is causing the heat...

One other thing to add, my battery level went from full to low in less than 2.5 hours when this happened. While I believe it was the battery that got hot, in reality I am not 100% sure. I do know that after turning Wifi off and charging the battery, the problem did not return. I am now very careful to toggle Wifi Off/On as my needs dictate. I do this even though I have set Wifi to turn off after 15 minutes from the advanced Wifi menu option. The Wifi 15 minute timeout was in effect when my phone got hot, so I am fairly certain it did not work as it should have. Hope this helps...
I've been noticing a good amount of heat up by the camera during moderate use. I thought this was a CM7 problem since I had been on it since day 1, but I am now on UnNamed and the problem persists. After some googling it does seem that many other people are having this problem. Not on WIFI, and not in a poor signal area either. Just wanted to see if anyone had any leads as to the cause. What is a good app for monitoring CPU usage by app?
Yes, it may get a little hot but it isn't something to worry about as far as I know. I've gamed for three hours straight and not had any problems except for a low battery life!
yeah mine gets hot near the camera during use but i dont think its a problem
I use a battery monitor.
From what I've read, it will shut off for protection. I've heard that as long as it doesn't ever get too much above 130 F, you should be OK.
Now if it constantly stays high, there may be a problem. Mine stays around 80 F most of the time and the highest I've ever seen is 99 F but i don't game much or use my camera. One thing you don't wanna do is charge it while hd gaming or charge it in a hot car. My infuse reached 146 F one time doing that.

Somehow 'Words with Friends' caused my phone to really warm up a lot. More so than I've seen with any other situation and on numerous occasions. Luckily I suck at that game and uninstalled it...
Mine is cool unless i put a thick case then itll burn up

When I first got CM7 running on this thing, I tore through the market installing the apps I'm used to. When I was finished, I noticed that it was indeed a bit warm in the area you described. It wasn't hot enough to cause discomfort, just warm enough to note.
I notice when my phone gets hot in that area when it is around 30% remaining and I charge it. I also notice that when it is charging, it really isn't charging but battery is draining. When I got home and charged it at 30%, I left it sitting there for about 30 minutes and when I checked the phone again, it was at 25%. GPS and wifi was turned off. I decided to power down the phone and remove the battery for 5 minutes. I started working fine after that. I noticed it getting hot again today when I plugged it in to charge at 40% but this time it actually was charging. I am running stock rom but rooted. Should this be a concern?
Seems as though a lot of people are having a variation of this problem. Hopefully it is addressed soon.
The CPU will always get a bit warm if it's running.
If it's getting very hot when the screen is off, you've probably got some background task wakelocking the phone.
My phone's screen gets pretty hot when I run web videos/flash videos on HSPA.
Runs a tiny bit warm when i'm running pristine 3D Tegra games on it...otherwise no.
The bottom right side of my NT heats up during normal use. Also the battery seems to discharge really fast? Is this normal or am I being paranoid. My previous NT overheated really bad once so I excahnged it.
I have been using it for about 30 minutes now after a full charge and its at 90% charge left.

I can feel it obviously
Is it possible you have a run away app that's eating up CPU cycles? Check your battery history and see if something sticks out.

I have noticed the battery getting warm, but it's usually when I've been browsing for a while. It doesn't feel super hot (like my laptop does) but it's warm. I haven't noticed terrible battery life. If I let it sit idle, it goes to about 50% in 8 hours time. If this is an issue, I want to know about it. I'll have to restore it to factory settings and whatnot, but I don't want a faulty device.

No its normal and is because deep sleep doesn't work, hopefully once CM9 gets released deep sleep be fixed.

There were a number of posts from people who were seeing high battery temps after skipping the OOBE. Did those of you having problems in this thread skip OOBE, uninstall B&N apps yourself, and/or use compromise the B&N applications/services in any way?
Just got mine. I noticed that it does get warm but not too warm to cause panic. Mobile phones start getting warm too if you've been browsing over wifi for a while. Are most people running frosty nooks? Should it not feel even a little warm?
Or maybe you can rate the amount of heat, say from 1-10 how hot does yours get?
My rooted nook gets hot while playing Exitium for half an hour, but not when it's idling.
Not I
I use my Nook tablet quite extensively and I don't seem to feel an unusual amount of heat coming from it. 30 minutes of use and down to 90% is not unusual either. Otherwise, I would have to agree that there is probably an app running your CPU full tilt. Probably not your battery that is heating up either, if you look at the pictures of these pulled apart, you would see that if the battery was what was getting warm, it would be almost the whole back of your NT.

I was actually thinking the same thing. I think the warmth I'm feeling is actually coming from the wifi adapter inside, which would make sense because I notice it when I'm browsing the web for a long time or downloading a large file.
No issues with heating up here.

Only time mine heats up is if I have been streaming from my pc to the tablet via dlna server to watch videos which would either mean its the wifi chip or the cpu heating up.

Just to clarify, you're saying if it is sitting idle - not being used, and the screen is off - for eight hours, it will drop 50% of the battery? I just picked mine up, and after almost 11 hours sitting idle it only lost 5% of the battery. It sounds like you might have an app causing a wakelock.
No heat in mine and it does retain charge while sitting with screen off. I rarely turn it off and charge every day or two depending on use. I read somewhere it is not good to let the battery go completely dead.
Not sure what OOBE is but I have been turning it off to avoid it from overheating really bad like my first book.
Not really sure how to scale it but I would guess maybe a 5 if a 10 is where it wouldn't turn on and a 1 is its cold to the touch.
I used Indrects method.
How would I check to see if a app is doing something like that? Tgps?
I guess I could just leave it on for a day then check to see how the battary is after like 15 - 20 hours.

I skipped OOBE, I used NARS to root. I don't have this problem.
Never heated up for me, not once.
Overall I'm more than pleased with battery life. Watched 40 mins of youtube 720p video with jetvd yesterday (over wifi) and battery went down only by 10%. My SGS2 would've lost like 60%.
Hello all! I have been a silent user of these forums for a while now. I am finally turning to you all for some help because I am unable to determine if the issues with my phone should be treated as related or unrelated.
My phone: Image attached, no outside URLs. In short, Galaxy S2, ATT, 4.0.3, not rooted.
I have had this phone since about March. Ironically, I had a model of the captivate that was subject to the random shut offs. ATT worked with me and since my upgrade was so close, they moved it up a bit. Badaboom this phone. Enough with the stories.
Applications: Some utilities I have on this phone include juice defender, advanced task killer, onavo data manager, eco battery protector. I do admit to the use of applications like instagram, facebook and browsing through some websites, but the effect on my phone is not necessary what I am looking to fix. Also, I use ADW, but I have been a long term user of ADW and find it to be light on my battery usage. Never even shows up in my battery summary. I just feel you should know.
The issue: My phone is being a pain in the rear. I am trying to determine if my overheating and poor battery life are related. When in idle, my phone can drain within about 5 hours. When I first started noticing this, I would make sure wifi and sync were off 'cause I really didn't need it on at work. Still, maybe saved myself 45min of battery life in idle (some screen usage to check time and w/e). Then when I charge, the phone gets so hot I start to worry. I was used to my captivate getting kind of hot, mostly because of the cheat cover, so I've stopped using it and charging with it. Right now, I mostly use a dock to charge my phone overnight, but still, when I take it off its hot as Hades.
Usage: I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much : I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much and that kind of drainage is normal). Heavy usage might include me using my phone as my GPS when driving. I do this while plugged in otherwise it would be off before I exit my hometown. The overheating gets so so so hot that I might unplug it for a bit and turn the AC on. :crying: Also, I use things like instagram, facebook, gizmodo but I make sure to kill those tasks when I am finished using the various utilities I have. I make sure I'm on wifi when I use those and I have them set to only working over wifi with onavo.
Other Issues: Recently, there have been issues with charging. I have had random moments where my phone does not register it is being plugged in until I pull the battery. At first I thought it was my car charger and maybe the fuse on it was a dud but when I got home and tried my dock, it was still nothing. Then I tried USB to my computer and still nothing. After a battery pull, this was fixed. Happened about 2 times over the past 2 months.
.. I don't know what to do to get a balance back. This has been going on for about 2 months now and I can't keep looking for a power source a mere 4 hours into usage.
I am considering looking towards rooting and seeing what customization I can do to manage my phone better and achieve a balance right for me. I am familiar with the process and proficient enough to work through it. Due to my phone feeling too new, I have been avoiding it. I would hate to shell the money out for a new battery, given this phone is less than a year old.
Please please please gurus .... I need your help. I don't know what to do to get back to having my smartphone work for me efficiently.
Well first get rid of the battery savers. In my experience they crashed my brothers phone and don't save battery in the slightest. Just remember to turn WiFi and data off using a toggle. Also download betterbatterystats from the xda forums and cpuspy from play store and let the phone do its thing for a day

Task killers do nothing. Juice defender used to help back in GB days. No longer needed. Just use the phone normally. Also did u say yer on the stock ICS kernel? I was gonna suggest a factory reset to clear data and cache but if yer on stock ICS kernel don't do that.
Sent from my SGH-I777 using Tapatalk 2
The first thing I would suggest is to get rid of the stock ICS root then custom rom ICS after that get a little app called battery calibration, fully charge the phone and calibrate the battery i have used this app and swear by it as far as juice defender i have used it and never really cared for it it really never did what is said it would.
So my battery has been running pretty decently throughout the day. Never have to charge it. Then I went to bed last night and decided not to put the charger in to treat it overnight. Starting at 23% but when I woke up seven hours later it was at 7%. I ran the code for wakelocks and it seemed to work, so I'm not sure what's up.

Im still having issues but not that bad. Im still around 40-45%.
It's pretty annoying..
Well I let my phone further discharge then plugged it in and went back to bed haha.
Woke up to a fully charged phone about half an hour ago and unplugged it. Still at 100% with heavy texting and XDA app..
Doesn't make sense, but we'll see.
I just charged to 100% and wiped battery stats cleared caches and rebooted. Gonna leave my phone alone for an hour then use it for an hour and see how shes doing.
Haha, she. That's cute.
Let me know how it works, I might do that if good results.
Has to be a she, i dont think i could love a man this deeply.
Oh you could! You gotta feel it deep down.
I give up.. its basically exactly the same. No matter what i do. Alarm manager seems to cause the most partial wake locks for me i think.. unless i have touch sounds on then its AudioOut_1 causing the most... im just gonna sit back and wait for aosp a magical fix everything button to show up on my screen.
Edit: I dont know what im doing anyway. Ill just save it for the pro's.
All of a sudden my phone has been deep sleeping.
I haven't really touched it since I unplugged it which was nearly an hour ago and it's still at 100%.
Most I did was take 2 pictures and send a couple text messages and turn my phone to silent.
But the OS is still marked as 55%. F.uck logic?
Edit: Scratch that, phone suddenly reading 97%. What do?
I dunno. I just no im not happy with my brand new phone not lasting a day off the charger. I only had it stock for an hour or two so im probably going to flash stock over the weekend and see how it runs for a couple days.
How heavy is your use? I'm almost convinced your drain is worse than mine.

The LG interface has a glitch with reading battery life. It bounces around quite a bit above 90%. It only gets exact at levels below 90%.
That's fine, but the problem remains.
It's not -horrid- drain, but my phone has been running on battery for the past 3 hours with little interaction and it's at 80%.
I don't know what could still be dropping it. I'm not expecting a perfect battery especially when I've had it for a few days, just doesn't make sense.
Freeze some apps that run in the background or simply delete them.

I haven't bought TB yet. Makes it a little hard to freeze.
Besides, it's the Android OS that's draining it. It sticks to 51-55% no matter what.
Keep Awake is the only thing that's constantly running.
I thought 40-50% is normal for Android OS?

"And remember, it is a percentage. The fewer other tasks you perform with the phone, the higher percentage of usage the Android O/S will be.
Basically, if your usage was 25% Display, 15% GPS, 10% Sync, 50% Android OS, and then you stopped using the display, turned off GPS, and killed the sync, your usage would be 100% android OS because you removed everything else using the battery."

To see what is keeping your phone from going into deep sleep, look for wake locks. I use better battery stats to monitor my phone.

I guess this makes sense considering everything else is really low. My brightness was at 0% during work so I wouldn't get caught texting haha.
The Keep Awake has shown improvement, on for 1h 44m after being unplugged for 5 hours. But near 30% drain seems to be a lot when barely touched.
I'm not concerned with the percentage number as much as I am the keep awake time. I believe if that gets under control, my battery live will be better. I'm not unhappy with going a whole day without charging, but I would like to see it get the best possible battery life.
