[Q] Lock ups and battery drain - Samsung Epic 4G Touch

I am hoping there is an easy way to troubleshoot and fix this issue. Every couple of days I can try to turn my screen on and nothing happens. I have to pull the battery to get it to come back up. When it comes up I notice the battery has dropped anywhere from 20-30%. I have tried a couple of different rom's. I am on the EL13 modem. I have tried the El26 and EL29 modem's but I have the same issue. I am not using any oc apps. How can I troubleshoot this and try to correct it?

When in doubt, backup, wipe, and flash the same or a different ROM. It's a bit tedious, but that usually fixes the problem. What ROM are you on right now?

I have done that. Was on caulkin's 2.8 now on the latest blazer. I believe it is related to the LOS bug. I just happened to be on a phone call when it happened again. It dropped the call and the screen went black but the phone didn't restart. I had to pull the battery and when it came up I had lost about 20% of the battery. Trying a different modem now.

There was a similar problem on the OG Epic...maybe this thread will help?
If it's not just a display issue (and something is actually draining the battery), I assume you've tried BetterBatteryStats? It usually works wonders for finding the source of wakelock problems.
EDIT: Actually responded to the question!

I have been trying to monitor this and it seems to be a different issue than what I thought. I thought it was related to the LOS but it isn't. My screen won't come and I have to reboot the phone. I think the battery level is just being shown incorrectly. I don't know why the screen won't come on. It is like it is asleep and won't wake up. I have been searching thru the forums and trying to monitor my phone processes to see what might be causing this. I have not found a solution yet. I have tried 3 different rom's so far and it seems to happen at least once a day regardless of the rom. I have wiped the phone and installed fresh. I have tried different modem versions and that didn't help either. Not sure what to do at this point.

when in doubt take it to sprint and get it swapped out.

im having this issue as well actually and i have to conclude that it's a battery display issue; my phone will be over 50% charged then drop as low as 8% when i reboot. i thought it went away with my last blazer flash but it still happens.

If it helps at all, I was/am running the MIUI rom and the phone would lock up on a nearly full charge at the same location. It was every time I walked out of class in the morning, the phone would just go black screen. I'd hold down the power, reboot, and wouldn't have that problem anywhere else. Hope this helps us find an answer.

[Q] Normal Stability?

Hello all. Ever since I got my EVO, I've been experiencing random restarts, even before I was rooted. Right now, I am running CM7.1 and Tiamat from kernel manager, and I probably have to do about 8 restarts and 5 battery pulls a day, no matter how often I use the phone. For instance, today I woke up and had to do a battery pull because the screen would not turn on. The light was also still orange despite the battery being fully charged. I unplugged it at about 8 in the morning and by 10 with no use, I had to pull the battery again because the screen was frozen off once again. Once I got it back on, the battery was down to 80%. I tried using it and half the apps would force close immediately, so I restarted... You get the picture. Some roms have been better than others, and kernels don't seem to make any difference, and I figured it was about normal. Then, I installed what is supposed to be a really buggy CM7 on my touchpad, and have only had to restart it once in the past 2 days, which makes me question how stable my phone actually should be. Does it seem like I should take it in to sprint, or is my experience about normal?
I also never overclock because of my already poor battery life and have tried underclocking, but don't see any noticible difference
bump. should I post somewhere else?
Run an RUU but stay s-off for the moment and see if the problem persists. If your phone begins working properly, then you can flash a recovery and flash whatever rom you want - but don't restore your backup. I'd start totally fresh if RUUing fixes your problems, don't restore your apps and data, just download them from the Market as you need them.
If the RUU doesn't help and the problem continues, take it in to Sprint. It's up to you if you want to s-on before taking it in - I've never heard of anyone getting problems from Sprint with s-off but without root, but I think it's a general rule to do so.
I hope everything works out for you!

I have heard and seen on here many times that random reboots are caused by battery problems, and bad software installs. Try calibrating the battery, also use battery monitor widget to see what ur batt temps are. Then reinstall all your apps, do not restore them then see if that helps.

I'll try an RUU when I get enough time to do some thorough testing. I have reinstalled everything directly from the market multiple times since I've had the phone, and also have used a total of four batteries with no change in behavior. I Will try the RUU soon though. Thanks for the replies

Need help with LOS on ICS rom....

I need some help and I was wondering if anyone here might have some ideas. I'm currently using Blend ICS FF18 v16.3. (fantastic ROM by the way). I'm currently experiencing a really annoying bug but I'm about 99% sure it's not ROM related because it first popped up on the last ROM I was using. I'm experiencing a bug where if I'm using the internet web surfing for more than a few minutes, I get the loss of signal circle and then the screen will flicker for a moment or two before the phone shuts off entirely. When I reboot the phone will now show 1-2% battery even if previously I was at a full charge. If I shut down again and plug in the charger for a few seconds and then reboot, the battery will be back to where it was before. Again this only happens when I'm using data such as browsing th web. Doesn't appear to occur during any other normal phone functions. Also, if I have the phone on the charger, the LOS bug doesn't seem to occur even if I'm using the internet.
Anyway, I've never had this issue before. It first popped up on the last ICS ROM I was using so I decided to try another ROM. I did a full wipe, and I also used Calks full format as well before flashing this ROM. Anyone come across this before or have any ideas? I know that LOS bug used to be notorious on this phone back in the day (I never suffered from it however) but I've never heard of a LOS and almost instant battery kill. Any suggestions would be greatly appreciated.

[Q] Why am I getting battery problems with GS3?

So here is the problem. My phone drains battery when there is nothing that is supposed to be draining it. In my house I have 4 bars reception (Max Reception) and wifi on or LTE. After using it for a bit and then closing all apps and shutting the screen. My phone starts its "heat mode", starts heating up. about 1 percent every 2 mins. I have tried stock, custom roms, and factory restoring and still nothing. I have had this problem for months now. Should bring it to my carrier company to fix it? Or is there another thing that's affecting it?
For the screenshots it starts off normal over night then it after use it declines.
EDIT: Problem on stock, stock rooted, carbon, hyperdrive, intergalactic
This does not sound like normal behavior. I'd use factory warranty and get a replacement.

Have you checked under settings / battery to see if anything is running high? Also check settings/applications and slide over to processes. Is it possible it is the media scanner? If so it could b a corrupted file possibly left behind from a theme or bad picture. You should be able to back up what you need from internal SD and do a factory reset from the settings. I accidently erased my external SD so use caution and read all it is asking. You shouldn't need to take it back yet.
Get Better Battery Stats and see if you can track down the wake lock that is killing it. It looks like from the last picture that once wifi was turned on, it experienced a hard drain.
Honestly, my phone does the same thing from time to time and I am still trying to figure out what it might be. In the interim, a reboot always fixes the problem.
I would warranty the phone. But just out of curiosity have you tried a different radio? Are you on the most up to date radio for your carrier? Also have you tried rebooting after the plummet starts and if so does it fix it for a while? I know that some postings have noted a problem with the LTE switch when on a phone call. I know that when I have LTE on and make any phone calls, at some random time over a few days it will happen to me until I reboot. If I keep LTE off, it does not happen. I am not saying this is your issue, but I am just trying to narrow the possibility.

Well thanks guys. Im going to send my phone back to my carrier. i think its antenna problems so i might get a replacement

Random Shutdowns - E980

Hello, I have recently re-flashed to stock on my E980, I am running the phone on the AIO network as an unlocked device (although it would run fine if it were ATT locked as well).
I am looking for ideas to why I am having a problem. So it goes like this...
The phone randomly turns off. It seems to happen in my pocket, not on the desk. When I go to turn it back on, it is unresponsive unless I pull the battery or plug it into AC. If I plug it in before pulling the battery, it says not enough power to turn on. If I pull the Battery and turn it on the homescreen loads and I have plenty of battery in the upper corner (75% or so). When the homescreen loads, its fine for awhile, then back to step 1.
I am currently unrooted (just flashed back using LG flash tools) however the problem was first noted on a rooted stock ROM. I installed CM11 thinking that maybe it was something in the ROM that was initally causing this and a new ROM was in store for me... Did it on CM 11 too. Then I reflashed to Stock and I am still having this issue.
I have tried most everything and my thought is that the battery is either toast or not being recognized properly. I do not have immediate access to a different battery, but I think i can get my hands on one... If I replace it, I'm thinking it would take me an hour or so to replicate the problem and I still wouldn't be certain that was the culprit.
Anyone have any ideas, or things I could try out before trying to source a test battery, or does this not sound like a battery issue?
hey
i got the same problem
gonna have new battery soon and see if its from this
the sell man told me its could be the ROM
gonna try the modem of e980H
I've been having a similar problem as you, and actually had the device factory reset while in my pocket. Going to try and find a battery around my area, and hoping it fixes the problem. Have you noticed any heating issues as well before the reboot?
yea its getting so heated and drain the battery so fast
i think cos its trying to find single i had that problem with rezound too
i think there connection when its got heat -> drain the battey > and also kills the battery after few times

Phone will not wake from sleep, needs reboot, massive battery drain

So, a few things: First, I used Sunshine on my phone last Wednesday to put the newest T-Mobile firmware on my phone. Prior to doing these two things, this problem did not exist. I am on ViperOne 3.5, chose T-Mobile as my carrier and was very careful in setting things up.
First two or so times I would notice my phone was not waking up, so I held down the power button to restart and after it turned on there was a very large battery drain (30-50%). After this I decided that maybe the firmware was the issue, so I fastboot flashed a fullwipe version through fastboot (originally I had done a no wipe flash) and restored backup nandroid from TWRP. After that the problem persisted, so I thought maybe it was a rom conflict and did a clean install of Viper 3.5, thought everything would be good but while in the car it did it again. This time I caught it quick (I had used my phone maybe five minutes before and when I restarted the battery drain was less than 5%. But seeing as I've done a clean install of both the firmware and the rom now, I'm sort of at a loss for what to do.
Has anyone heard of this, or would anyone have tips on what to do? Can provide additional info if needed, just want to get this worked out. I've been lucky so far and it's done it while I didn't need power. If it were to do it during work when I can't check the phone for a while, it could lead to the entire battery being depleted.
::EDIT:: I should also add that this happened once when I was asleep, and I found that the phone would not charge when in this state, as the orange light was not on when I woke up and I had to reboot the phone. Again, extremely weird and it only started after Sunshine and firmware change, nothing else.
This "sleep of death" thing has happened to me a few times, though I have not seen the battery drain. I have not figured out what is causing it.

I actually just caught it and tested some more out. Tried plugging it into a wall and it won't charge. Also tried plugging it into a computer and it will not recognize. The only two things I have changed are the firmware version, and running sunshine through it. I'm actually pretty worried since it won't even interface with a computer until rebooted. Also went from 90ish% to 77 in a matter of 15 or so minutes
