[Q] KF2 battery problem after CM10 install

Hi, new here but I've been lurking for a while.
I followed Powerpoint's guide to instal CM10 on my KF2
http://forum.xda-developers.com/showthread.php?t=2105077
Everything was running great and has been since I first loaded version 3 a few weeks ago, and last week i went to version 4 of powerpoint's rom with no problems. Then a couple days ago after i had been browsing the internet on it for maybe 30 minutes, I set it down and when i came back the screen was off and wouldn't turn back on. so i figured the battery was just dead, so i plugged it in to the wall charger. At first the charge/power light wouldn't come on at all. Then after several plugs and unplugs the orange light started to come on but would only stay illuminated for 30 seconds-ish. So I tried it on my phone charger and the orange light came on and stayed on, so i decided to let it charge overnight. The next morning the light was still glowing orange so I unplugged it and tried turning it on, but still nothing happens. But when I plugged it back in afterwards the light came on green. now it has been plugged in for almost a day with the green light on but it still wont turn on.
Anyone else have this problem? Any ideas what i can try? for obvious reasons i can't exactly ship it back to amazon lol
p.s. I have a final on friday and the text book for that class is on the kindle. So urgent responses will be greatly appreciated.

Nevermind guys, I figured it out. Power button for 20 and it booted right up

I've had this a couple of times on both 10.1 ROMs. As you stated the only way I got it working was to hold the power button for 20 secs, then power on normally.

It just happened to me again, seems to be a recurring problem. Anyone have a clue what's causing this?
on a side note, perhaps this problem could be dealt with simply by installing a battery management app like juicedeffender. any thoughts?

Wow, for once I can completely and knowledgeably help with almost no guess work!
The issue is Sleep of Death.
The cause is unknown, and due to the nature of how to reset it, it's been difficult to get logs. It happened to FMK not too long ago and last I heard he was going to get the logs (to find what causes this) and get those to Hashcode to look at potential fixes.
It's not battery related....well in the sense that, if it happened, you reset the device, and looked at the battery, it should be at a similar level to what it was before.
TO FIX
You guys were right on fixing it mostly.
If you ever press power a few times and it won't turn it, don't bother fretting about it. Just do the hard reset, which is holding the button down for 10 seconds. After you do that the device will reset to the point where if you just press the power button once, it will boot up like normal.
I would hold it down for about 15 seconds just in case, or if you have headphones it, you can here when it does the reset and can get used to the timing.
I would say....in a few weeks with the device, I've had the issue around 5-6 times.
I've also NEVER had it happen while I'm doing things, so it hasn't caused issues besides making me a wait a bit before using the device, which is good. If it happened during doing things I would want this fixed ASAP, but so far, no major issues.

agreed, if it was happening while i was trying to do stuff it would be problem. As it is though, I just consider it a minor inconvenience. Glad to know I'm not the only one experiencing this though.

I wouldn't call it a fix. I would call that a workaround. We need a fix, and I think if anyone could get an effing log to hashcode of it happening, we could fix the problem. I think it is a kernel problem, what with the recent merges and such. I think something is incorrectly copying from kf1 to kf2... if anyone understands what I'm trying to say, it makes sense..

I wonder if pulling the log cat via adb would work, I.e. wait till it goes wrong' then connect it to a PC to pull the log. The issue is its very random and being at a PC to do it when it goes wrong could be tricky.

LG G3 D855 shutsdown on its own

Hello,
So I bought a G3 the day before yesterday and yesterday was my first day with it, and for that first day my phone had shutdown twice on its own. The first time was when my phone was lying on the bed and doing nothing, it had around 50% battery and was not hot or anything.
The second time was this night i don't know when, i have put my G3 on the charger and went to sleep i woke up and it had shutdown.
I didn't made factory reset when i got i from the box which i will when i come home from work and hopefully this will fix it, but does anyone have a problem like that? If is something serious i will be disappointed to return the phone.
p.s. My previous phone was galaxy s2 and had this king of problem only with custom roms and kernels, but i have not put anything on the G3 yet, except activating the developers options and had switched it to ART and the first time the phone had shutdown i thought that the art was the issue and switched it back to dalvik, the second time though was on dalvik.

I have the exact same problem. The past few days when I go to bed and wake up in the morning, the phone has shut itself off. I haven't rooted or installed any custom roms.

I would advise you both to take a factory reset, only install apps you need for a few days and see if the problem persists, if it doesn't install your apps back one by one as it may well be a particular app causing the reboots.
If you still get reboots after the reset and with no apps installed then you may have to take the phone back to swap it.

Yes as I said in the first post the factory format and hard reset will be the first thing that will be done as soon I am at home. About the apps i have pretty much basic apps (facebook, messenger, soundcloud, etc) all from the market except smashhit of which i have the apk and installed from the internal memory.
Except those apps I have 2 mp3s and some wallpapers and nothing else, becouse when i got my phone it was late on the evening and i had no time to do anything else. So the phone is pretty much out off the box and I was verry frustrated when the secound shutdown happened, becouse i tought the first was from the ART runtime.
Anyway today I will have more time to spend on the phone and we will see what will happend.
p.s. The phone does not reboots, just shuts off.

Is it definitely off or is the phone just stuck on a black screen? It is quite common on some devices when something is not quite right for the kernel to be unable to wake the phone up, the phone is still technically on but stuck in deep sleep.
does holding the power button for 2 seconds turn it on? or do you have to hold it for say 7-8 seconds?

It is definetly shut down around 2 seconds(the normal time to hold the power button to turn on) it turns on and work perfectly and does not show anything suspicious in its behavior, it's super fast, not laggy and etc, may be a little high on ram consumptions but with this havy skin i think it is normal or could not be normal idk, the ram consumptions go from about 1,2GB the lowest i have seen to up to 2,3 the highes i have seen.
Anyway about the shut off think yes defenetly 100% sure it is off, it happend again a while ago and i thoght the same thing may be it si deep asleep even i had chacked the weather 10 min ago and call myself from a friends phone and the operator said that the phone is off or i am somewhere without network covarage.

i got same problem. it turn off it selft and black screen even battery still 70%. rmust remove the battery to restart again, ealy bad. huft

If you have to remove the battery to get it to restart then its not actually shut off, its just stuck in deep sleep! which is usually caused by a bad app.

Yes if you have to remove the battery the problem is different, i just have to push the power button and it boots right away after it have shuted off by its self........

i didnt have this issue with my 855. but i did a factory reset after i got the phone just for the hell of it

So it's reset time i finally have some time to the some staff on the phone so hopefully everything will be fine. I will post if this fix or not the problem to inform the other people in this thread.

did you have any luck with the problem? I have the same issue, performed a factory reset and restored, hopefully it will fix too..

Hi all!
I have and have had the same problem and think I've pinpointed the problem to Google Search but can't 100% confirm it yet. I didn't do a factory reset when I got the phone and it shutdown during the night. I did a factory reset, made sure it got enough time to update everything properly. Problem was gone and worked fine. HOWEVER, the phone kept asking me which home screen I prefer at random times when I hit the home button. With random I mean like 4+ times per day. I searched the net and found a threat saying that a guy with a G2 solved the problem by removing Google Search updates. So I decided to do just that and get the factory version back and the questions disappeared but guess what, the phone shut down the following night.
Any takers or might this just be random? Note that it was working fine for three days with the updated Google Search and shutdown the first night after the downgrade.

So I did hard reset and so far so good the phone had not shutted down itself, and I updated everything which need to be updated (mentioning this for the guy with the upper post). So far so good I will keep you in touch if something goes bad...

The problem will be resolved?

I suggest take it to your dealer and get it replaced asap. I've seen lots of returned phones(my job at XXXXXXX company ) with the same issue, and as long as the defect is reproducible the dealer will give you a new phone. If it's outa replacement period then they'll probably repair it.

aaaaaaaaaaaaaaaaaaaaand shut down again but this time it took quite a bit time longer to shut off by its self so i tought the problem was fixed, but it's not, so i am going to the store which i buy it from to replace the device.....

Does this also happen with the korean models?

Desperate for help with random reboots and shutdowns (all non stock Roms)

Guys,
I hate to do this but I really need some help. I am trying to troubleshoot my d851 which has random reboots and shutdowns with any rom other than stock. I have tried pretty much any ROM you can think of including PAC, Mahdi, Liquid etc.. This happens completely at rabdkm and can happen while the phone is just on the table or when I am surfing the web.
I downloaded catlog in an attempt to catch what is causing the crash but so far I have nothing ( not even sure I am using it right, I have no experience with debugging or things like that).
I used Catlog to record and actually had the phone reboot while it was recording so I might have something in that log but I have no idea what to look for
Any chance one of you fine folks is willing to help me? Any help would be greatly appreciated.

i also have same problem, my phone shuts down and restarts sometime on stock rom as well.
after it shuts down, it does not power on normally so i have to plug power cable and then switch it on.
i dont know why it does like that, how to fix it??

Ummm, would you be willing to try something? If yes, before replacing battery, open the hidden menu, i-e
Code:
3845#*851#
On the dialer app, navigate to ‘Thermal Daemon Mitigation OFF’ and turn it on.
After that please restart, check if it shuts down at 50 percent again, if it does, please repaeat the proceedure but this time activate ‘High Temperature Property OFF' option.
Restart, then see if it shuts down at 50% battery power. If it still does, please disable both options and restart again.
Check one last time in the third scenario, if it still shuts off, please go on with replacing battery.
I am suggesting this because after installing Liveboot by @Chainfire, I have noticed the thermal daemon giving some errors at bootup, I disabled the daemon and now it doesn't shutdown on its own. I hope this is the case. Anyway, no harm in trying.

For me it was the battery ?

Same issue
Replaced battery once a mobile repairer is saying that this is the issue with battery should i try a new battery and anyone tell me if this is solved by changing the battery or not

G3 randomly turns off for a few hours

Hi XDA,
My friend her G3 randomly shuts down sometimes, and it's impossible to boot it again for a while. After several hours it'll boot again on its own, and it seems like it went into some sort of hibernation since she doesn't have to enter her pin or anything.
Things she tried include removing the battery, holding down the power button for a long duration and charging the phone. Last time this happened the phone was at roughly 30% battery.
Does anyone here maybe have an idea what it could be or what a possible solution would be? It sounds like a very strange and improbably issue to me.
Thanks for reading!

This is due to kernal panic.
Flash stock firmware may be this will fix your problem

Thank you straight flashing back stock may be a quick fix most of the time but we dont figure out the cause so we end up in the same boat cause we try to tweak the same tweaks. I dont claim to have the answers and yours could be correct. And i also accept critisism if im wrong

This could be a battery error. Is your battery old or new?. Otherwise it could be a kernel issue which can be caused by under volting or other tweaks within the kernel. If you are on stock ROM with stock kernel the only option is bad battery or hardware issue. Try factory resetting your phone if this doesn't work it is likely to be a hardware issue

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.
