Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?
Bump. 10 signs.
Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)
Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)
Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]
Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?
May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.
I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.
Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since

That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.
Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every
That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.
I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!
Do you have any email accounts configured in the mail application?
This happened once or twice - I rebooted the phone and all was peachy.
Sounds like you have a rogue process wearin it out.
Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...

I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.
the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.
I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.
this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?
i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.
This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.
The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.
i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?
I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol
This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.
Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.
The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

I installed this using the Moderate setting, and then selected those options as recommended in preferences.
Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.
I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.
Make sure the GPS is turned Off, too...
All these answers and the easy ones were not mentioned..
Make sure you shut your AUTO SYNC off...
Make sure you lower your brightneess....
Make sure you turn off GPS(was stated above me)
Turn off your wifi if you are not using it.. make sure you are not transmitting your hot spot stuff...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.
When I look at my battery usage I saw that my S2 is constantly awake, even when I turn the screen off and put the phone away for a couple of hours.
I've turned off Wifi/3G and even background sync, but it stays awake all the time causing the battery to drain a lot faster than I want. Is there a way to stop this?
I hear people talking about theirs dropping only a couple percent per hour when not using the phone but mine at least drains 10% per hour.
Could it be the Social Hub?
Btw, my S2 runs on the latest KE2 firmware.
For me, I've noticed a big decrease in idle-battery draining when I rooted and removed Social Hub and I never even used it. It still stays "awake" as much as it did before on the little lines in the battery usage app, but a lot more juice.
Used to lose 10% per hour like you, now more like 5%.
If it stays awake all the time, something is _wrong_. If I don't use my phone the only awake time I can see in the battery status is every 15 mins (approx) when it goes "awake" a couple of seconds to update all the **** I have updating. It never stays awake all the time.
edit:
And just to give some more info. Mine is still stock on KE2 with all the crap Samsung put in the phone still in place.

I think I experienced the same thing this night. I lost about 10% in 7 hours but the graph still showed that my phone was awake all the time.
Again, I turned the Wifi and 3G off. I'm still running the stock KE2 firmware together with all the Samsung apps. I haven't rooted it yet.
Also, Maps and Social Hub seemed to be active a lot when I look at their stay awake times.
bump.
to much awake time here as well.
how can i find out whats causing it?
I'd put money on it being widgets. Remove all the widgets from home screens, restart the phone and see if that fixes it. You can thank me later ;-)

try watchdog, or adb logcat
I have this problem from time to time, killing wifi sharing stopped it for me. Comes back once a day for no reason I can see. 1 Kill a day keeps the phone last a full day for me.

Yeah I also see the occasional WTF moment when the phone suddenly decides in the middle of the day to stay awake 100% of the time. Battery then drains about the same 5-10% an hour you see. Not sure what causes it but a reboot usually fixes it, battery drain goes back to 0.5%-2% an hour that it usually sits at.
Sometimes I also see wifi sharing eating a constant ~50% of CPU, at which point battery drains more like 25% an hour, though not sure if it's related. If only I could disable the damn thing without rooting.
I also have this weird problem. My 2g data connection remains on because I receive a lot of emails so Ive enabled push notifications. However the problem is even when the screen is off, the phone stays awake 100% of the time.
I went to sleep after completely charging the phone at around 11pm and when I woke up at around 9 am, the battery was at 30%. That is 70% battery gone for not doing anything at all. Really need a solution for this guys. Or should I just turn off my data connection?
i had this prob with Widgetsoid installed.
Problem gone when i removed it.
Find on XDA BetterBatteryStats app.. Use phone for a while then run app. Check detected wakelocks. Based on that you can hunt which app or widget keep device always on.
Phone works normally if you compare Screen On and Awake graphs. Both graphs should match. Awake periods can be sometimes be out of screen-on intervals, but no too often.
In my case, I found that maps keep my phone awake.. then I figired that weather widget kep tracking my location (and uses maps for this). Also Lattitude uses maps to track location. When I configure weather widget to not track my location (im usually always in a home town) and turn off latitude, lots of awake periods dissaperar.
And spare parts doesn't work. Any other way to check what's keeping it awake?

try installing aLogCat and see if there's anything fishy on the logs (namely programs trying to background update more than they should... Java exceptions can often be a source of resource leakage if not handled correctly by the program that throws them).
WatchDog is also a good tool to see what's taking a toll on the CPU. I once found out that WeatherBug would keep the CPU topped up if kept in an area without internet connectivity as a result of some mishandled code error or something.

Watchdog
Hi. I am having similar problems. I downloaded Watch Dog lite and have used Battery Usage to see that Android System is using much of my battery even when asleep (overall, it is about ~46% of usage).
I have Wi-Fi turned to "Never On When Sleep" (or whatever the setting is) and I've noticed that when I look at Battery Usage, the blue bar that corresponds with Awake is nearly identical to that of Wi-Fi. I've also noticed that when I hit the sleep button, and create a break in the Screen On blue bar, there is not an immediate corresponding break in the Awake or Wi-Fi blue bars despite my settings. Is this normal?
Any help would be greatly appreciated.
what I can't tell is the difference between awake and up time...with the evo it was blatant but I can't figure out if the phone is actually "awake"
I think "Up Time" is time from last reboot and "Awake" is time since the phone is pulled out of sleep (either by turning the screen on, syncing data, background data collecting information, or etc).
Hopefully I'm correct...

That IS EXACTLY CORRECT. you get a cookie.
My NS4G is having problems sleeping, as well. Seems to be awake around 25% of the time, whereas actual screen-on time is about 10-12%.
