[Q] Epic is overheaing

Okay so my epic recently started overheaing again. This first started happening 3 months ago til I took it to my local sprint shop and they fixed it for free. They said not to overcharge my phone and that they had to boost my battery. To further explan my problem, my epic gets really hot when browsing the internet but regardless of that, I just leave my phone in my pocket and next think I know when I try to unlock it is that it shutdown. When it happens, I have no idea. I can't even turn the phone on unless I remove the battery and put it back in. I'm running cm7 (the latest update from 10/22) andi listen to music in my car and most of the time its plugged into my car charger since the battery life is currently horrible on cm7.
So does anyone have any idea of how I can personally fix this or boost it? Its been more than a year so I'm not sure if sprint wll fix it for free.

Dont know what to say except for maybe you need a new battery! I have an extended battery and even though its a bigger battery with way more juice than the oem version, I still get about the same i did on eh17 [stock] but the random reboot thing has happened to me but I never had to battery pull to get it working. I am currently on cm7 too and I noticed that it only happens when its really low battery that it reboots or shuts down saying 0 when I am at like 5%...? but for the most part I think you might need to to a odin to stock and update ota to get ei22 if you want that modem or do ec05 and just use the modem-update zip found in the dev section, after you reflash cm7. my phone never over heats! oops once! I was watching movies on it all day with the wifi and via speaker from netflix but thats the only time. maybe you also might have a very aggressive app running in the background, and thats whats heating up your pocket! are you using tegrak for oc?

Thanks for your time man but not I'm not running anything to oc. I never oc because I really have no need for it. Neither am I running any aggressive apps. I tried leting my battery cool down overnight by taking it out and leaving it next to the window but no luck. The worst part is, this shutdown happens unless I constantly check my phone and use it. If I don't use it for like more than 30mins, it turns off and I hav to do a battery pull. And most of the time after the battery pull, my charge drops from like 90% to 15%

You said your running CM7? I remember on CM7 I couldn't even use the phone or it would reboot due to heat also. You should switch to maybe a different ROM if you'd like more use of the phone or wait patiently for a fix to this issue. I tried asking about this problem in the CM7 thread a month back and no one else seemed to have this issue but me.

I just flashed the EI22 Legendary Rom thru clockwork and same issue.. left the battery out for the second night in a row.. but it still overheats.. hopefully sprint takes care of this for me

Sounds to me like you might have a bad phone, and or battery. I know mine gets hot when using a lot of data like streaming music, or sitting in car dock in hot summer... with out putting ac on it... ><
But it does get pretty warm but not to hot to hold when in a pouch and streaming music from network via bluetooth to a speaker at work. Never had a reboot or shutdown from heat doing that. Only time I had it shut down due to heat was one time in summer in the car dock.. Streaming heat + 110F don't help.
Sounds like hardware to me. If it does it on stock and different roms.

Hmmm, i'm on legendary rom 4.0 with th IAP kernel and i've noticed that when surfing the net for a few hours or playing a game for a few hours the battery will get hot enough to fry an egg it seems. before installing EI22 i noticed it would shut down due to overheat but now I stop all activity on my own cause it gets way hotter than ever before and i'm nervous it's gonna fry. The phone I don't think is recognizing the battery is overheating anymore! Not sure. Thing is, I noticed before ever rooting that this overheating would happen if playing a game for too long on my phone. But doing same exact thing on a friends EVO didn't get hot at all!

Well if you are getting that hot then there is an issue. I work at a Radio Shack*i need different job badly.* and have seen a few phones where it is hardware or even battery related that they are to hot to hold really.
What games were you playing? maybe i will give it a try and see what my phone does. I do have the angry birds, fieldrunners, peggle, plant vs zombie, zenonia 3.. no issues when playing them for a bit.
The thing that gets my phone the hottest is to stream from like google music or xiia live*shoutcast streams* to a bluetooth speaker like I said above. Though streaming to internal speaker or headphones/speakers doesn't get to warm just slightly.

the game I was playing was drag racing (has happened with cut the rope too). Just played it yesterday and no problems. played for like 3 hours straight to test it. This was also after I had organized all the apps and things on my phone. I had found a ton of programs constantly running in the background and other things going on at the same time. Just a big mess. Cleaned it up and no overheating problems now. I think for me it's just something that's gonna happen once in a while when I got too much going on on my phone.

Overheating. Big Deal?

Long time lurker here. I have a One X I got on launch and it has been very good so far, no issues at all and great build quality. However, I noticed that today I had issues with getting a signal (had to restart my phone 3 times to get a signal) and then after charging my phone it got very hot and went from 100% to 64% battery in 8 mins. However, since then I have charged it and it seems fine again, battery back to normal. Is this just a one off or is it a sign than the phone is going on the blink? I don't really wanna return/replace it, so would I be sensible to just put it down to an anomaly or is this a sign that the phone is buggered?

Well it depends if you have a custom rom/mods/root/buggy apps. Sometimes it's just a blip in the Android system. It takes quite a bit of testing to point out the problem.

Unfortunately this wasn't a one off. Tried charging the phone today and after being on charge for 7 hours, the phone got very very hot and the battery actually went down 20%. Going to return it. Shame, fit and finish was perfect on it

If you don't see any games/strange apps running in Task Manager, then yea, sounds like something wrong.
Might try Factory reset, just to be sure and don't rush anything when its setting up, don't do any reboots unless it asks, so that you don't interrupt any setup process. When I got mine, I didn't reboot for first few days (because I didn't even have a need to do that).

I just felt that my phone got overheat. When I download file using 3g. Was this normal?
Sent from my HTC One X using Tapatalk 2

The charge time on my phone was scandalous so hopefully that was restricted to the one phone also, took 12 hours one time to get from 40-80%.
To make things even better, I can't get my sim to work on my old phone now! Hopefully Amazon send me a new one pretty quickly

I got my new phone today but the fit and finish isn't so good. The volume button rattles which is annoying. The 3 soft keys also don't vibrate when I touch them which is strange. Anyone else had this problem?

Get betterbatterystats & see what's eating your battery,
Which app does the android battery stats show as your main battery consumptions?
As for overheating, get a temp app & see what its running at - although hot to touch, it might be in safe regions - HTC have said its completely normal to run at ie. 55c

[Q] Galaxy Nexus shutting down

My GSM Galaxy Nexus has been experiencing random shut-downs, especially when it is in my pocket. I haven't noticed any problem with overheating and I tried rooting it and installing the latest version of ICS 4.0.4 directly from Google's source.
I also have Lightflow installed, but I doubt that it causes shut-downs, since I've only heard of reboot problems.
I suspect it could be a problem with the battery because, whenever this happens, the charge level goes down by at least 5% or more.
So, does anybody know how to remedy this? Or will I have to exchange the phone?

This has happened to me a couple times. I never know how long it's been off. I'll take it out of my pocket, and it's just totally off. I hold the power button and it starts up. Very frustrating bug though... as rare as it may be.
I'm still stock, unrooted 4.0.2 using the extended battery on VZW. Holding out for the first update, then we'll see...

Just so you know next time that happens grab a log and post it. Also, if you battery is down, try wiping stats, that usually brings it back.

Sorry for being such an ignorant and a noob but by log you mean a crash log right? Which is the best way to obtain them?

This happens to me about once a day. I'll come back to the phone and it will just be off. I aslo have root and lightflow installed. What's the best log to get?

It was the battery for me...
This was happening to me too, almost every time I took my phone out of my pocket, it was turned off.
After a couple weeks of troubleshooting and googling, I figured out what it was. It was the phone getting "twisted" in my pocket from sitting and standing. If you twist your phone like your're trying to wring water out of it (not too hard), the battery loosens just enough to cause the phone to lose power. I fixed this by taping a thin piece of foam to the inside of the battery cover to keep the battery in place. Makes the back of phone feel firmer too.

Hello !
I'm experiencing the same kind of power off.
Very often it's in my pocket, but sometimes not.
I've leave the debug mode on for the day, so last time it happens to me i've save a "abd bugreport" to a file.
Is there any clue that can be found in this file to know why the phone shutdown ?
Regards,
Antoine
EDIT : I have YAKJU 4.1 stock ROM, no root, no unlock.

I noticed a while ago before seeing the videos that if I banged my GN against the table a certain way against its bottom left corner that it would shut down. I solved that like the poster above by putting an extra something in between the battery and the cover (paper). That solved lots of the problems I had with my phone shutting down when I put it down on hard surfaces. There is though, I believe, a second software caused issue for some of the shutdowns. I still pick it up once every couple days to find that it's off. I've banged it, tapped it, twisted it, and I can't get it to shut down physically like that anymore.
I'd like to know more about how to pull the logs and find out what's going on.

I've had my Nexus for three days now, and I've had several shutdowns. Two of them were during a phone call, and the other two were during a workout using micoach app. The twisting/pocket option doesn't apply to me, because during the calls I was holding it in my hand, and during the workout it was strapped to my arm. I also have lightflow, and will uninstall to see if there is any difference. Running totally stock unrooted 4.1.1. This is making the phone totally unreliable, and I will return it if I can't get this fixed soon.

Every would have had that problem due to how poorly Samsung constructed the battery slot for the battery to fit it. What I did to fix that problem was take out the battery. Even from time to time rage quit and rip the battery out while the phone was on. And put it in, and push it a bit up toward the camera. That fixed my battery issues. Others have put a foam thing (sorry I don't know the name) where the battery slot golden things were so the battery wouldn't move. You can also try that.
Galaxy Nexus-codenameandroid rom

I uninstalled Lightflow after posting my previous message, and since then have not had any random shutdowns. All calls are performed flawlessly, and I've used micoach several times again (this was when the problem was most obvious) without any problem. I haven't changed anything else, so I'm pointing my finger at Lightflow. I'm installing it again to make sure it was the cause, will report back.
Regarding the battery problem, I've been looking at it and can't see how it can become loose. It is really tight, and there is no spare room to add any kind foam. Maybe thye have tweaked the design on later batches? My GN was built March 2012.

I had the same issue and it was caused by an app. The app "Boid", a twitter client still in beta, was causing the reboots. The reboots occurred once or twice a week, they happened on 100% stock ICS, 100% stock JB, custom roms also.

Like the above poster, I uninstalled LightFlow and am no longer having any issues. I'll try and get in touch with the developer and see if there are any logs I can get to help.

Extremely high phone temp!

Does anyone have issues with your SGSII T989 phones having extremely high temps?
I get it when using the GPS, charging the phone while i'm talking on the phone, and doing a few other activities. It did not do this on my first purchase of the phone and i'm a bit weary of the temps as sometiems it gets quite warm!
Currently I'm on O.E. SGS II Rom w/ root, that's about it! No OC no mods or anything of that sort. (Just CWM and Root).
Any tips would be greatly appreciated, as this heat as caused me from using my phone each day more and more.
P.S. I WAS on Juggernaut Rom and then flashed back to Stock, and it was having this heating issue then, should i try to do a complete 100% wipe like on one of the development threads and start from scratch like I just got the phone from the factory again? I wiped my system using Odin and it seems to of kept my old programs, no information like games and etc. was kept however, does anyone think that might be the problem? Once again thanks!

If you are rooted you might want to try a different kernel and maybe SetCPU. I had some overheating/temp issues a while back and after I lowered my CPU a bit and set it to an Ondemand state with a profile for screen off running CPU very low when not actively in use it seemed to fix the problem.. Btw SetCPU is free for XDA users, there is a thread somewhere in the Android Hacking Apps forum..

Edit: I thought it was free to xda users, I checked and cant find the thread, maybe I was wrong or they changed it..

I'm on the stock kernal, I was on the modified 1.7ghz kernal before i believe, as I could overclock over that, but i just recently stopped that and went back to stock. I was and still am expecting the phone to malfunction on me sometime soon lol. It's been a really reliable phone so far! My G1 and Mytouch 3G slide (gf's phone) took soo many dumps on me while I used it. Each of those phones were probably sent back 5-8 times and they were kept completely stock for a while!
Back on subject though. Any kernals that go well with the factory rom? I don't favor any aftermarket roms right now as they're not stable enough for my usage IMO.

I have heat problems but I've always had the stock kernel...
Sent from my SGH-T989 using XDA

Undervolt at the stock clock if you want to lower temps. However, charging will always increase heat especially if you are using the phone at the same time, and depending on ambient temps.

Dude my moms sgsII literally got fried because it heated up once. She was using her phone normally and all of a sudden it started heating up. She kept using it and the next day the phone won't turn on, charge or get into download mode. It looked like what a hard brick would look like. So I just returned it for a HTC one S.
Btw she was on full stock.
My phone heats up a lot because I'm down south with 90-95 degree temps and I keep phone in the car dock by the windshield but it never failed on me.
Sent from my SGH-T989 using XDA

I thought it was a well fixable issue. Guess not? lol... Either way, everytime my batt temps rise, i notice i get 40-45C and i start to get worried. So if i'm in a car, i'd just put it next to the AC vent while the car's running and temps get down to about 25C and i'm good again. I just don't feel comfortable with the phone anymore like I use to. It never did this before, why now??

I have an app that warns when it goes over 40 and it happens daily. I was downloading torrents one time and it keeps the screen active while downloading and the thing got like 62 celsius before I realized what happened. It almost burnt my hand lol. if your ever in sunlight or palming the phone while using gps on 4g.
overheating is very common with this phone I wouldn't worrie about it to much it is uncomfortable though if in your pocket

Also remember, any app that uses hardware acceleration for graphics or video (games, browser, etc.) or gps will cause the phone to heat up if used for a prolonged period of time.
Playing Osmos was like setting my phone on fire.

Are you sure I shouldn't worry? I mean, I don't want solder points falling off due to too high of a temp. Then again these temps don't even reach 100C yet. I've got the same app too probably, it's a battery monitor that tells u when the phone gets too hot. mine's goes off everytime i'm around 40+

Yep, I use GPS and often. It's just so much easier than guessing your way off a piece of paper. But yeah, like you the phone gets soo hottttttt. I have to always put the phone to my AC vent.

It's normal to a point.
These are serious computers we have.
Think of the old P486's back in the day, those things needed huge heat sinks and some even had fans
our phones which is what, 4x the cpu power and not only no heat sink but everything is squished together inbetween a hot screen and a hot battery
That being said, I use a program called A-see, which is to watch my security cameras while out.
And if I forget to close it out (Actually exit the program) It will keep running and running and eventually probably fry my phone
lets put it this way, I will actually start to feel it in my jeans pocket, it gets that hot.
Also I have a program which will alert me if my phone gets to 130 degrees F
And will automatically shut the phone down if it gets to 140
overheat protection or something

I had this issue where whenever I try to charge my phone it would overheat to the point unbearable to touch I went back to stock flash different roms in the end i exchanged it it was still under warranty

Serious over heating issue

So ive had my Tmobile G4 for about 3 weeks now. Ive been using the G series since it started. I love the G4 but wow ive never had a phone with this type of heating issue.
There is not a time when the phone js not at least warm to touch. Few times a day it gets to the point where its too hot to touch at all. Forget about making a phone call way to hot to lut against face.
Im not doing muxh of anything either. Web browse etc... But its hot at idle screen off just sitting there.
Anyone have issues with heating? Multiple times its given me the over heating message and shuts off phone.
Last night for example it got to 80c.... Thats fricken hot!
Could factory reset help it? I dont know what to do at this point? Am i just having to get a replacement? As i type this from my g4 sensors showing high 60 to low 70C.
The heat is generating from the top half of the phone btw. Like at the camera it feels like.
Any suggestions or help? Thanks

Is the battery draining abnormally fast? Check the usage for play service, could need that fix

If you live in a hot area like me, such as LA, then you probably experienced phone shutting down while using phone as a GPS due to the overheat.
I've never Had that problems with all of my previous phones but I'd give few software updates for optimization.

Yeah battery is draibing very fasy. I use a battery monitor and nothing is sucking it up.
Also, i live in Arizona where it has been 110 degrees daily. Though it hasnt shut down from heat outside or when using gps yet.
It shut down with over heat warning last night in my apartment where its 67 degrees in here while i was on google.com just browsing. So im clueless right now.
I just cleared cache partition and booted to safe mode to see if it runs any better.
I can leave my phone on my table for an hour and pick it up and itll still be scorching hot doing nothing. Its literally never not hot to touch.

Yeah. That's the mytmobile app... Unchecked all the boxes in the settings. Helped me

My 1st Tmobile G4 Online Preorder had some problems mostly screen. I sent it back. I went to the store and bought one. That one was always hot as well. It was always throwing warnings at me. I had Gmaps on in my car with the AC on and only 70F out the time and it shut down on me. I called Tmobile and did some master reset etc and still was the same. I finally just went back to the store and told them to exchange it after they seen how hot it got in store. Tired to tell me I was at 15days when I went back in but I called in a few days before and asked what day was the 14th Monday or Tuesday I guess they count Purchase day as day 1 and that's what I thought but the person I talked to said no but they called Manager and they honored it. This phone finally seems to be good a few little issue's but they should get worked out soon with software we all hope. The 1st 2 phone's I had the Update Pushed to my phone the 3rd one was already on the phone so might be newer batch ? I was not happy spending over $600 on the phone with the issue's I had on those til this 3rd one which is good so far.

Then I'd say that even when it's doing nothing, it's still actually doing something, maybe just something it shouldn't be doing.
My Verizon G4 ran warm, and I was disappointed with the battery life. Different monitoring tools were unable to point me to what app (?) was causing the problem. Sometimes it would stay cooler after a reboot. Mine was never just constantly hot, however. Mine would be cool sometimes when sitting around, and then sometimes warm. Like taking it off the charger in the mornings, some days it would be cool, others it would be warm (~95F or so), when it had been just sitting there with the screen off.

Just now for example. After i replied here i out my phone on my table. I just now picked it up and it was 74 C. Scorching. Like its just gonna melt ibro a pile of G4 goo lol.
I guess ill call my store on Monday. Safe mode and clearing cache partition didnt help at all.

Are you using a case with it? I recently had overheating issues and figured out that the leather wallet case I was using was causing my G4 leather to overheat. It went as high as 112°5F But as soon as removed it it went back to normal.

Nah I have the black version normal backing not the leather version. I have the thin Tech21 case but i took it off a week ago to see if this helps.
As im typing this my phone is at 75C which is 167 degrees F! So hot!
Possible a Facorty reset could help? I really dont have many apps installed right now either. Since its relatively new ive been slowly installing apps. I started blank, didnt install anything from backups etc. The apps i do have installed are pretty basic. Nothing syncing or running. Ive been clear the recents aswell just to try. Frustrating

Have you tried turning off WiFi? I've noticed occasionally that my phone will constantly drop WiFi on my home router and reconnect a few seconds later, repeating this until I restart the router. All of that constant disconnecting and reconnecting makes it pretty hot...

Yeah its happening regardless. I turn data off when im on wifi and my wifi never loses connection, it stays constant. Though i did try a few days ago using no data or wifi and same dral, just hot.

Have you tried a factory reset? I leave my wifi on and stream music and everything. The only time it gets warm is when I Fast Charge. But I mostly wirelessly charge so its still cool.
Maybe you should exchange it.

I'm second on that doing factory reset. Seems like you have a corrupted profile or rogue app, or both.

What sensors are you referring to? With wich app? That's fundamental

I were having over heating problems on my G4. It were so hot at one point that my 6 year old daughter picked it up to play a game on it. The phone was that hot my daughter actually started crying cause the phone burnt her hand. This is not good. I have an awful lot of applications on my handset, over 300 so before I contacted LG I did a LG backup and reset. I restored probably half the apps what I had and a week after I haven't had a problem and the phone seems to be running as it should. The phone isn't even warm.
My theory is the G4 has 64bit processors. The snapdragon 810 processors were known for over heating and the G4 uses the snapdragon 808 processors for this reason. The 64bit processors deal with twice the data at the same time to the old 32bit processors and this contributes to them getting too hot. I feel that a few tweaks by developers and updates from LG is what's needed to combat the over heating. Time is our friend here and a bit of common sense. When you install a new app and overheating occurs then just remove the problem app. I always see how the app affects the handset now for over heating problems.
The 64bit processors in the G4 are new and need to have some updates to combat the overheating I feel. I recommend a system restore, debloating and only using the apps what you need.
I remember when pc's went from 32bit to 64bit processors. There were processors burning out, melting, water cooling became popular and bigger fans to combat the over heating. In time it sorted itself out so I feel this is the case for the G4 and other new handsets running 64bit processors.
Hope this helps.

Did anyone try unchecking the boxes in the my T-Mobile app? My phone went from 50% to %5 in less than 30 mins running crazy hot. You could also try uninstalling the app updates, or using the debloater tool on xda to disable it.
Sent from my LG-H811 using Tapatalk

Same here, although not so hot that it "burns". iPhone 6 got warm but never so hot - software improvements should help combat this over time. +1 on the debloat tool.
One may argue the dead air via removable back cover can act as an insulator vs a compact design. Maybe just get an Otterbox/Thick case so you can't notice the heat as much? Could possibly lower battery lifespan though.

I've had my AT&T G4 for a little over a week. The first couple days the battery life was horrendous so I did a factory reset. The battery life improved greatly however that's when I noticed the top half of my screen getting unbearably hot. Another factory reset didn't solve the issue. So I talked with an AT&T Rep and am taking mine in for a replacement now. Hopefully will resolve this issue. Will update.
