Heavy N4 problems, any suggestions? - Galaxy Note 4 Q&A, Help & Troubleshooting

So, my phone have been having a lot of heavy problems. This has been going on for a while and i'm not sure what to do. The problems include:
- Extreme laggyness
- Heavy battery drain (2-3 SOT)
- Random reboots
- Random freezes
- Not rebooting
- Only rebooting in recovery
- Dying at 30-40% batt, and bootlooping until I put a new battery (a fully charged one) or charge it
I have tried full wipes, custom ROM's and stock ROM's but nothing seems to work. Atm I'm running stock android 6.0.1.
Is there anyone having the same problems (or have had the same problems) and has any ideas on how to fix it? I have to 3.5 more months until i can get a new phone so it's pretty necessary.

same(ish) issues...
I have the same issues... And I'we also tried "everything" .
I am starting to belive that this has to be some kind of hardware failure... it seems like some use in a way eats up all the memory... I have also tried to stop all background processes, but this doesn't seem to have any effect. The problems happen on all ROMs I'we tried, so it cant be software... But I'm no expert...
One thing that seems to help is not using some google apps, like chrome, and hangouts... When I launched this app it just died right away, but after uninstalling them, it "lives" a bit longer...
glad for any help I can get...

Disable app optimising in battery settings.
Use wake lock from app store and set to level 4.
☆Try a new battery☆
I had every issue you have listed... I replaced the battery with a new official samsung battery and it's been perfect since, not even a single reboot.

Had some ideas about the problem being the battery (I use an external charger) but to me it didn't make sense because I don't see how the battery could influence the software. You only had the problems with the battery or also the other ones (bootloops, lagginess, freezes, strange messages like 'sim card was removed')?
Thanks for your response.

Had all the same issues as you guys. The freezing, lagging, apps crashing and restarting at like 90% then boot looping until plugged on to charge. I tried all solutions, different roms, downgrading, completely stock. Bit it was the battery replacement that solved it finally.

No problem man, I honestly didn't think it would work at first. But I was suprised when It did. It's like a new phone

great!
edit: My most notable change was actually to remove the memcard.... As I'we read about the memcard issues...
It sounds so strange...
I actually tried some stuff for my self... Let debugging run and when it seems to get worked up, I'd just let it lie, I aslo tried tweaking the kernel, so that not so many background processes run at the same time. I'we had it running for about 18 hours straight! Last night I was browsing, installing apps and changing icons and fooling around with settings on 13% battery. Alarm worked this morning, and I'we been using it for more or less as I would use my s6, but a bit more patiently. At about 48% while running Instagram and play music it suddenly crashed. Now its up and running again.
Its still very clear that something isn't right and I will look into your battery solution...
Thax alot for you contribution! :good:

Here what I have done !
Hi dear !
I were facing this problem a month ago as my
phone gets reboot randomly as well as
shutting down by it self at 60 % !!!
Can you imagine that !
What I have done dear that I changed my
' class 4 ' microSD card to a new ' class 10 ' one as well
as I have changed the battery !
And you know what dear !
I have no longer facing this problem !
It had been resolved !
Now my phone is working fine since the last month !!
Hope it helps ??

Hi folks! I was having the same issues too apart from the battery drain. My phone was lagging, restarting, getting stuck on the 'Note 4' bootup screen. I reflashed and reset. Cleared Cache etc etc. But I also got a mmc_read error. Apparently it was an internal memory error. So I sent it back to be repaired as it's just under warranty. Looking on the repair status I *think* they've ordered a replacement mainboard and will be installing it. I'll also order a new battery when it comes back.

Can anyone recommend place or web site to buy genuine Samsung battery as 99% there is counterfeit ones?
Yes, bad battery makes your phone unstable. Had same issues on Note 1. When bought new battery all gone.
Thanks

Thank You Samsung !!

[Q] Cyanogen mod 7 HD2 ran out of battery....

Hey Guys,
So flashed my phone with the cyanogen mod 7 2.4.1 and has been working great.
Yesterday arvo it ran out of battery and shut down, however it has enough battery that it can boot, but seems to get stuck at the little android man stage.
Ive tried alot of methods mentioned in a wp7 thread, however none have helped.
Is there anyway im going to be able to boot into my old rom or is it a matter of reflashing?
Its weird, cause it doesnt run out and then shut down, it just sits at the little android man...
Any help would be appreciated .
Cheers
Alex
So the battery is all good. It will just stay on the android booting stage, and not run out of battery, or reboot. Well sounds like you data got corrupted so you might need to reflash.
ugghh, corrupted just because it ran out of battery?
sigh
Well, im going to try one last thing- leaving it charge on tri colour screen for a few hours and then try booting. If that doesnt work ill reflash
note to self- set titanium backup up to do routine backups!!
Just reflash it. It only takes a couple of minutes, especially if you've got a nandroid backup. Running the battery down shouldn't corrupt the image. I've run mine down to 0 a few times without this happening.
but i cant reflash without losing all my msgs etc. can i?
thats the only reason im trying to save it.

CyanogenMod battery drain
Hi all,
has someone noticed that CyanogenMod 7 on HD2 drains battery ?!
Someone can tell me how to fix it ?!
Thanks.
actually cyanogen mod 7 drains my battery way more slowly than any deshd build i have tried before CM7. One charge lasts for like two days or so. All deshd builds usually had a battery runtime of less than a day for me.

Using SetCpu, and setting up profiles has helped for me. Also, I noticed that the first couple of days, I had high battery drain, but once everything settled, the battery drains settled. I also use system panel which will tell you what apps are eating up the most power. If I notice that an app is hogging resources, then I'll uninstall, especially is it's something that I rarely use or don't need.
Ok for me. I simply restart my sd gingerbread androïd. And my android consums only 6mA in sleeping mode.
Hope it helps

HD2 HUGE BATTERY DRAIN 1% every 1 minute

Hi my hd2 is on a stock windows mobile rom and has a huge battery drain, every 1 minute or so i lose 1% of my battery and even on standby its the same.
Please can anyone help!!!! I have just flashed a stock rom from sd and have nothing on it and it still does it!
did you flash another radio rom? battery performance has a lot to do with it.
formatting your sd card could also help.
I've tried formatting my sd card and have tried flashing many radio roms right now im on the latest one (2.15...) and still it does it.
well the latest doesn't mean that it's the best for you. it depends on your carrier and area. but this wouldn't result in such a high battery drain.
sorry i can't help you then. i would try to make a freash install with task 29 and everything and if it's still not better try another battery.
Ive tried everything..no one knows anything about it
Thanks anyways
Would appreciate if anyone else has this problem too?
Sounds more like your battery is on the way out. Do you have another you could test?
Yupp, i have 3 standard htc batterys and 2 of them are brand new and still it happens
You did not say how long you have had the HD2, whether this problem has occurred from the beginning, or had just recently started. If it's been that way from the time you got it, it needs to go back to the vendor/seller for replacement. If it has suddenly started, what has changed? Other recent threads here note that a change in GMail was causing problems with high CPU levels and fast battery drain. I believe you said in one response that two of your three batteries have this problem. I assume that one of the batteries does not. If so, it sounds like bad batteries.
Sorry i meant to say that every battery that i try, it still has the problem. And also i brought this phone (used) with no problems and i put android on it, one day it turned extremely hot whilst i put it on charge, then what used to happen was whenever i left my phone on standby (screen off) my phone would switch off. But then i changed my charger cable and that problem was fixed but now i have this problem.
In that case could be the cable not supplying enough charge to the battery, or the phone reading battery stats incorrectly. Other than that I'm at a loss.
Tried everything :/
Thanks anyways I guess its just time for the bin :/

Are you using Gmail? There have been a lot of reports about overheating and battery drain from gmail accounts. Evidently there was some change in the way Google handles their accounts.
Nope, not using gmail
theres nothing on my rom as i just flashed it.
if you flashed it new and the problems started at this point you can try to wipe the battery stats in cwm. don't really now what exactly that does but it's worth a try.

thats providing hes running it and not using a stock winmo 6.5 rom
Yeah, im using a stock windowsmobile rom so no clockworkmod unfortunately..
oh right. there was something with windows on this phone ^^ sorry already forgot that.
Hi, did you try the following?
Switch off the phone completely and then remove the battery for approx. 15 to 20 seconds. Then put it in again and start the phone.
When I used this procedure the battery drain was normal again.
BR rainer
tried that still no luck :/
Take out the sim AND sd card. Maybe one of them is going bad.

[q](STUCK) MULTIPLE ISSUES

Hey guys.
there are several major problems with my device.
first of all, lets see what we have here.
Exynos powered SM-N900 note 3 device
About 2 months old
rooted with CF- Auto Root
4.4.2 N900XXUDNA6_N900SERDNA6_SER firmware
that was the situation of device when the first problem showed itself.
Whiel i was watching video from an sd card, suddenly ı realised even if the device is on charge, (wall type) the battery percentage was dropping. when ı saw that, ı stopped watching the video, put down the phone and went to sleep. (it was 15 % at that time)
after 8 hours of proper sleep, I took my phone and saw that it was just 60%.
then ı began searching for slow charging issues. tried exactly everything about it, no luck. ( 5 different brands of different cables, 3 different brands of wall chargers, 2 different original note 3 batteries. tried both for AC and USB charging.)
All of them gave me the same result of charging current of 300 mah.
then ı tried all the wipe options, (wipe from recovery, factory reset from the settings menu, flashing another firmware which is CAC-N900XXUDNA8-20140210150816. ) still no luck. and things started to get worse.
a pain in the ass lag showed up, I'cant even use the camera. its like it comes and goes, but most of the time its there.
slow charging still continues, sometimes it does not charge at all,(had to reset couple of times) and when it charges, it's always 300 Mah and shows in the battery section as USB all the time ( even if I'm charging with the wall charger) ( already tried cache wipe for this, didn't make any difference.)
When I plug it to the PC, it does not recognize the device as a usb device, nor Kies, but ODİN does. (thankfully).
got this really weird screen, and some other screens close to it. (the screen actually faded away like in the picture ı uploaded. waited for it to go out for 10-15 seconds when ı pushed the wake button, the screen came itself just like nothing else happened 10 seconds ago!)
those are my problems, and the device is rooted, there is no warranty issue, so that means I'm stuck. it's not my first android device, and i consider myself just above average android user, but my hands are tied for this. any kind of help would be greatly appreciated!!
Really? No one can answer that?

Did u try charging when mobile is off?if not give a try
Thanks for the reply.
Yeah I tried that. It kind of shortens the time of charging, but still, there are also other problems and some way ı think all of them are connected. That can be a solution only for slow charging, but the other issues still there.

may all your problems linked each other possible, try to uninstall third party apps you have installed, may some app is causing all the problems.

I'm afraid that is also not a solution, because i already performed a full wipe and flashed a clean firmware, which cleared all 3rd party apps, still problems go on.

are you suggesting EFS back-up /restore?
By the way, i have fresh brand new issues!!
now device doesn't close, if i close it and connect it to a charger, it reboots itself to recovery mode!!!
ı discovered something about the lag issue. if i run the cpu enough, (like playing games) lag goes out. when ı quit the game, it turns back!!
I opened up cpu monitor from the developer options, everytime lag shows up, i see from the cpu list this thing:
irq/563-sii8240
I think this causes all of my problems.
any ideas???

It looks like a problem with a interrupt of the video driver. I read you already flashed a other firmware, correct?

Have you installed any apps to monitor battery drain? I use GSAM Battery Monitor and every time I start to see weird things with my battery, I have a look to see which app is running wild. Removing the app usually sets my phone back to very good battery life. The other day HD Widgets updated their app and all of a sudden I was dropping battery life about 15% per hour when hardly using the phone. HD was the culprit, removing it put me back to normal again. This happens often when companies update their apps.
One other thing, does you phone run hot? In the notification screen, you can see the current temp of your phone. If your battery is draining fast, it will run hot.
Thank you for the feedback. I downloaded the app, here are my first results. Do you think its normal that my kernel alone 74% ? I recently turned into cvm recovery, any ideas for alternative kernels?

B321a is the firmware that you had problem with? There are many people that have same problem, but most of people experienced better battery life (like me). Hard to say what is going on, the only thing i can say is that my upgrade proces was B200 > B317 > B321 > B321a. I dont know if it does make any difference, but if you have time you can try the same process. No one can help you with this.
Im now on b321a and see how.it goes

I dont knowm but i can tell you, i had the same problem with B200 when i got the phone, it was very frustrating, not even one day the batery could stand, but then i tried first beta of mashmallow and it got like twice of the battery life. Yesterday i was almost all day flashing some stuff (that didnt work) so i restarted the phone into recovery like 10 times, almost every time i had to restore backup and was trying something else, and at the evening i still had about 30-40 percent.

So u being still on the beta? Should be B317 or something. The B321 is the final one. Listen I am a bit desperate as having this phone charged to make 24hrs of medium use is frustrating

huawei´s smartphones are pretty weird, many people have various problems, some have problems that others dont etc, for example, many ppl says that B200 had better battery life than Marshmallow, for me, its twice as that, so its pretty individual, i was frustrated about this phone when i got it, at first i was happy for new phone, but the smile dissapeared very fast. Now, with MM im pretty happy, just pitty that we dont have CM or some mods (yet). Last thing i can suggest you ist, try to install xposed, then install Amplifiy app, i could help
im also desperate to the point the phones going!
ive had wifi off mobile data off gps off
Phones been on since 7am so basically 12 hours and im at 30% battery with 1h 30 min screen on time and 1h20m talk time!
its so god damn bad ............oh and greenify just says no apps need to hibernate.
ive got a couple of screen blemishes anyway so i might try a rma as its well with in warranty any how.
It seems that major prob for me have been google maps. Sounds like our device doesn't cope well with this app. Removing those off gave me normal SOT and phone can make 1.5 day easily

In Settings > advanced > battery > consumption
What are the top things that are using your battery?
check energy plan
Did you check your energy plan settings? After I first upgraded to 321 I observed battery drain as well. I managed to solve the issue by changing the energy plan in the battery manager. After upgrade it was set to performance. Once I set it to intelligent battery drain was ok. Seems like after upgrading performance is the default setting.
PS: The names might be slightly different, because the langugae on my P8 is not english.

GApps on Rooted LG V20

Does anybody know if we are able to flash any other versions of GApps on the rooted LG V20?
My V20 is from AT&T and since day one it has had terrible battery life. Where I was able to use my Note7 or Droid Turbo all day and still have battery left, the V20 eats the battery charge like Sally Struthers in a See's Candy warehouse. I mean, I have to charge this thing at least 2 times a day when I use it to search the web or any battery intensive purposes. I never had this problem on any other phone. I have been trying to find ways to improve my battery. I used Rom Toolbox Pro to disable all kinds of stuff, and it worked great, until my phone started Grand Mal seizing giving me the Google Play Services has to close notifications, which I then had to factory reset just to get my phone working properly again.
I would like to try flashing a minimal version of GApps that pretty much just has the play store and play store services. Are we able to do this on our V20's without having any issues? If you have any input at all I would really appreciate it.
IMHO it must be an app or two you have installed draining your battery like that. On a full charge I can a whole day and a little in to the next. I am a heavy user too. Are you blasting the brightness at 100% all the time? If so auto brightness will help a little. Go in to setting and see what is using that much drain

I was thinking it might be something I installed, as well. But I can't seem to pinpoint any apps that might be causing the battery drain. I keep the screen on auto brightness like you mentioned so it shouldn't be the screen. GSam almost always shows the Android System and Kernel (Android OS) at the top of the list of battery-draining apps. I love the phone, I just cannot figure out what is going on. I mean, I am not doing anything different than I have on my previous phones, and the V20 seems to be working fine. I thought maybe it is something with Nougat. I will gladly post some pics of app usage or data if it might help figure this problem out.

What rom are you on? Are you on stock white theme? I'm running a dark theme, which can help save a little juice. I'm also running as many team blackout apps as I can (many Google apps) to avoid all the whiteness. Just throwing out some ideas.

Interesting! I have never heard of Team Blackout Apps, they look pretty nice! Yes, I am on the stock ROM just the way it comes. I haven't changed anything at all. I have barely installed any apps just to see if I can find what is causing the battery to drain. Are there any other ROMs that work with the AT&T variant of the LG V20? It seems like they haven't made any yet for the AT&T V20. I am still waiting for Xposed to be released that is compatible with nougat so I can use Amplify.

I don't think there are any roms for AT&T variant atm. I did see an AT&T user flashed the stock deodexed rom by tilde88 in rom section. Not sure of all the details though. I'm assuming you would lose some functionality...would need to flash stock kernel as well.
What is your leading source of battery drain under system usage?

Yeah definitely, I think it is a little bit too early, for me at least, to expetiment with a deodexed ROM. But I know there will be some awesome developments coming out soon. I was so happy to see that a root was figured out for the V20 so quickly after it was released. Until then, I will keep experimenting with the stock ROM.

Hi Swizzle82, thank you for the reply. It is kind of difficult for me to pinpoint what the leading source of battery drain is because the apps seem to bunch all detected processes and wakelocks together. I know that Call Services & Android System show up on top a lot of the time, but since I factory reset the phone today, the stats are minimal compared to what I previously had. WeChat also uses resources, but I used that app all the time on my Note7 and previous phones, even more than I do now, and it never caused a problem. I attached some screenshots from GSam, BetterBatteryStats, Wakelock Detector, and CPU Spy Reloaded., I don't know if they will help, but just switching between those few apps and taking some screenshots over the span of 6 minutes, my battery percentage dropped from 79% to 76%.

I had android system for a while killing me.. I factory reset and setup every app one by one with no data transfer or anything. Installed every app like it's first install. I charged it til it reached 100 percent, with the phone plugged in, I went to data/system/batterystars.bin and deleted that file and rebooted. It was a long process but it hasn't been an issue since. This was when the phone first came out last month. Never knew which apps data it was but it is gone now.

That sounds like a good idea to try. I will do this today since I already factory reset it yesterday. I would rather do it now before I get further into using it again. I have not heard about this until you mentioned it so maybe there is an issue with app transfers with the V20 causing it. The battery does seem to drain less than before, but it seems like there are still some issues. Thank you for the suggestion!

If you followed did the dirtysanta method, make sure you flash the Konverged kernel for the H918. Or Tilde88's 5.1 kernel for the H918. It worked wonders on improving battery life. Also make sure you disable Lookout - that drains a lot of battery it seemed to me at least. I usually get about a day and a half of battery life when I use my normal amount (which is honestly quite a bit).

Okay, thanks for letting me know! I have not even looked at those kernels thinking they weren't cross compatible with H910. I am going to try it right now with the dirtysanta method. I will disable Lookout, as well. There are a ton of apps that I never use that drain the battery. I will let you know how it goes :good:
Did you own a V10 or other Lg phone prior?

No, I had the Note7 before getting the LG V20. Before that I had a Note 4 and a Droid Turbo. This is my first LG phone and I really do love it. I actually like it more than the Note7, the only problem I have is the battery. I do think that factory resetting and manually installing the apps instead of restoring them will help, and using the Konverged kernel seems promising, from what I am reading.

Yup I always start fresh and install apps manually anytime I reset my phone. I think it's always nice to start fresh - even if it is sometimes a bit inconvenient to go through all the apps you've installed and choosing which ones to install. Hopefully you get it all sorted out!

Okay, I just factory reset the phone, rooted it with DirtySanta, and flashed the Konverged kernel and the phone is NOTICEABLY faster and smoother! This is great! Each time I reset the phone, it had noticeable lag. I just figured it would go away over time, which it did, and that it was because it had to load and download everything since it was fresh. But with the Konverged kernel, it has none of the lag and is silky smooth! Time to manually install the apps I want and disable some stuff I don't need. I will update you guys after I see how the battery is with the new setup Thanks a lot for your help, I really appreciate all the input!:good:
I need your help! I changed the screen cover sensor to off not realizing that I would not be able to turn off the static after rebooting my phone since the sensor is off. Would somebody please post a few screenshots showing how to navigate to the screen sensor settings so I can tap my way there and turn it back on? I am trying but there is no way to tell where to tap with all the static. Thank you!
Nevermind, I fixed it! I finally navigated to the second screen settings and turned it off when the screen is off and that got rid of the static after I turned the screen off then on again. Note to self, never do that again LOL.

Wow I'm fairly impressed you managed to do all that with the static screen haha - glad to hear it worked out for you in the end.
Get me your stock system.img and boot.img, and I'll make you a modded ROM with a custom kernel!

Haha yeah, I never knew something like that could cause such a huge problem. Now I can't seem to find what I did to cause that in the first place. I have been looking through all of the settings and can't seem to find anything that affects the proximity sensor. On top of that, the screen rotation stopped working, it will not rotate when I turn the phone to the side to type. I have toggled all of the motion and second screen settings, calibrated the motion sensor, and nothing is affecting it. When I turn the main screen off, the sensor does not shut off the second screen when I cover it with my finger, and the phone does not recognize when I rotate the screen. I am kind of at a loss on how to fix it.
