[Q] i9505 turns off when stressed

Dear Friends,
I'm having a rare problem with my S4.
All used to be fine but now suddenly the device turns itself off when it's stressed. By stressed I mean during a call while switching to another application or watching a video for more than a few minutes. To me it seems like a battery broken because once I unplug the AC cable and run the benchmark the phone shuts off and usually when it gets to the GPU/Video related tests. When I plug in the AC cable and run the test everything works as usual.
Also when the phone has turned off randomly the phone has problems booting up. It will get to the omega boot animation restart again. The intervals are always different. Sometimes the logo spins for a few seconds and then it reboots again, sometimes it happens right away when the logo appears. Its almost that the phone does not have enough juice to boot up eventhough the battery is charged with 40% or so.
Once I plug in the AC cable the phone boots up normally. I doubt that it's the custom Rom (Omega 9.0 with stock omega kernel) that is causing the problem. It seems hardware related. I'm guessing:
- GPU
- Battery
What do you think is causing those random turn-offs ?
Should I exchange the battery or flash stock rom to check if it still happens?
Why does it make a difference if the AC cable is plugged in? can it be anything that is not battery related?
I'd love to have your opinions!
Best,
Thomas

Your using XXUBMGA right? I had this weird problem where the screen wouldnt turn back on unless i pulled the battery. I switched to the german firmware and all is fine. Its not hardware, trust me, same prob.

First go to stock rom mate, then check

Weird thing is i was using stock, even though exxi is using a modified rom it might not play nice with root/custom kernels. Dont know for sure though; just what i have observed directly.

Friends,
I've installed the Pre-Rooted Stock Rom UBMGA via Odin. Cleaned the phone completely. It booted up and during the first Sign up process (google account, wifi network setup etc.) it went off again with 80% charge. When I plug it to the charger I can continue the setup normally. It seems that whenver it starts any GPU related process (Video animation, Antutu menchmark, Quadrant, Games) it turns off without warning. I ordered a new bat. hopefully it will arrive next week but until then I will not know if the issue is battery or phone related. at this point I doubt that it's ROM related. What's your judgement on this?
Best,
Thomas

Any news? I've had Omega v7 and like two weeks ago it started to turn off suddenly... I thought battery run of or something, later on when this turn off happened and I turned phone on I had "black screen of death" or what to call it.. no launcher but status bar was ok, when I dragged status bar down I could open settings and change "homescreen" to basic and than back to normal and it worked...but... I couldn't use home button, it just showed black window that disappeared immediately. I backed up data and flashed Omega v11, after "tutorial" just after choosing language it showed this black screen again, so I've begun being suspicious it's hardware related. Morning after that it was working okey. Well...not really.. in app list one page of app was showing shadows of icons instead of icons, when i scrolled trough all pages it fixed. Later that day it turned off again. No turning off omega symbol, just.. like if you pull out battery. And those shadow icons were on two app pages. I've flashed nandroid backup of original ROM and when I browse gallery fast it turn off again... I suppose it's hardware related as it's not stuck to specific ROM. Maybe wrong battery? but more like motherboard I think. It also broke my sd card, because of multiple power failures probably. Also after this turn off battery drops down for like 10% or more. First screenshot - shadow icons..second screenshot - battery % drop

i have the same problem with one of the last stock release, in last 2 days my phone's system was totaly burnt because i've played a lot with roms kernels and tweak, and it started to give me also this kind of problem. So i flash by odin one of last stock firmware and it's ok, after a few minutes i've rooted again the rom and charged phone from 19% (at this percentage the phone turn off) to 100%. it seems to be okay, but at 63% it turn off again, so i pull out battery for some minutes, and after it continues to turn of after a few seconds...
(one of the tweak that i made was using "battery calibration" it clean battery stas that can be damaged by skipping between various rom, i used it a lot on galaxy nexus but maby this can be one of/the reason of problem)
Have u resolved by changing the battery???

Dear folks,
It's a battery related problem. When I changed the battery for a mumbi type new battery the phone works with no turning off. Problem resolved

[Q] AT&T S4 Battery Drain when Plugged and Charging extremely slow.

Hope someone can help me solve this issue.
The Setup
I recently went out of the country and before I left I unlocked my GS4 following from wonderhowto[dot]com
Arrived to my Carribean destination, bought a prepaid SIM, popped her in and everything worked great.
Problems started when I flew back into Miami. I removed my prepaid SIM and installed my old one, changed my APN name back
and rebooted the phone. Decided to plug it into my laptop (USB3.0) to get some extra juice before the next flight and I noticed that
the battery was actually going down and quite quickly too, about 1% every 3 minutes. The phone was also doing a lot of connecting and disconnecting from the laptop even though it was not being moved.
I use two batteries which I have an external charger for , so this didn't slow me down too much.
After a few days, I thought maybe by unlocking the phone I had left it in some "roaming" state where it was eating up battery looking for its signal, so I decided that I'd restore it to the nandroid backup ROM Manager created before I did the unlock procedure. OH NUGGETS!
Things got ugly , quick!. In the process of trying to restore got MD5 mismatch error, so I went back to 3 previous backups before all of which said either "MD5 mismatch" or unable to open .zip -None of them worked.
Thankfully I had saved a copy of the backup folder in clockworkmod to my PC and tried to load that, it started and then get to writing /data and said error writing data.
I rebooted. Bootloop.
After a few hours of attempts with KIES, and some well timed cold beer deliveries from my wife, I finally got the phone back to stock version.
Rooted it again, motochopper, And loaded GoldenEye Rom v 8.0 . Still slow to little or no charging.
Loaded PACMAN and noticed something that should be mentioned.
Pacman rom has its own little battery widget that sits in the top tray and shows the %. It glows green from bottom to top to show that it is charging. I noticed on every couple of cycles, the battery meter would flash red for a quick second before turning green and sweeping up.????
Went back to a backup of GoldenEye8.
The current status
The phone is currently plugged in to the stock charger (2A) and stock cable. It has charged up only about 3% in 20 minutes time. I have it in battery saving mode with wifi on , and EVERYTHING else turned off.
Battery info says:
Temp 87.3 F
Voltage 4033mV
Plugged True
Charging
Li-ion
Health:Good
Charge Type : AC
Battery use shows 62% of battery use coming from SCREEN (Yes I have auto-brightness set, and NO live wallpaper)
Anyone have some good input?

Maybe its a bad cord? Or bad USB port/connection on the phone it self...

62% screen usage is normal, I sometimes see over 70% with my brightness all the way up.
Make sure apps aren't keeping it from going idle and staying active.
Battery temp. seems a bit high. General causes of that are a faulty cable.
Download greenify and hibernate any apps that may be running unnoticeably in the background.
If your kernel allows fast charging (disables access to phone storage while fast charging is on) enable it while charging if you're not using the phone.
Play with CPU and GPU governors in your kernel to save battery life. I.E: I put my CPU governor on "powersave" while idle and not using the phone for anything extensive.

Tried two other cords,but they just made it worse. They actually caused it to look like its charging but the battery level was going down.
Your second suggestion is probably right, but i'd like to exhaust my options first before having to restore and send to creator. I do find that with the stock cable and no external case on it stays plugged in well and doesn't make any "interrupted connection" noises.
With stock charger and cable and minimal functions running its charging about 1% every 4 minutes. ( Approx 6.5 hrs to full charge )
I feel like the hardware must be working in order to do that, and that the software is putting some kind of excessive strain on it. Possibly?
The battery use still shows, screen as the major contributor at 61% , so I switched from a really high resolution static background to a low res one. ( results to follow)
Downloading WanamLite now and going to try that out, also going to try performing the unlock procedure I did in reverse order and see what that does. Keep you posted. Open to suggestions.

Thanks for the advise, I'm running greenify and its really only showing facebook and my sms app, I hibernated facebook anyways just to test it, but I know out of the box , on a car adapter this thing was charging 1%/min , maybe I have a bad ROM/Kernel mix?

Doubt it, but maybe you can try going from touchwiz to aosp. Very much more lightweight, though you'll lose some s4 features. If it is faulty hardware/battery I'd just save yourself the trouble and swap it for a new one; or try another battery. I guess you can try doing a compete wipe and flashing a fresh ROM with a kernel you know will definitely run smooth with it.

Already tried the second battery, no luck. Any suggestion on the rom/kernel combo?

I use task650 with kt's kernel and it's excellent. Though it's all opinion, there is many great combinations. Some ROMs come packaged with their own kernel or a custom one.

IMO: those temps are pretty normal.
Why you don't try a bone stock rom and see how it respond for a few hours, if the stock rom behaves the same, probably you will need to send it for warranty.

Battery malfunction

I tried to look on the internet regarding this issue but it doesn't seem to be a common one. So I was using my S4 normally, browsing the internet, I could swear the battery was at 70s%, and suddenly it restarts and battery is now at 0% then it restarts again shows 0% and keeps restarting until it stays off after several restarts (I pulled out the battery twice because it restarted many times). It may sound like an error in reading the battery percentage but after I pull out the battery and plug it into the charger it still shows 0% and charges normally. This happened three times which forced me to ask about it here.
P.S. battery is about the same age as the phone, got it back in june. I am using the original battery that came with the phone.
P.S.S. not rooted

Try clearing your dalvik-cache and cache (that'll clear the battery stats).

[Q] My Nexus did something strange... is it of any concern

I have been using TWRP and Beanstalk ROM for some time, and the current version installed has been there about two weeks with Hellscore kernel, never had any issues or problems, its been pretty flawless and I have been very happy with it. I also run a tool called AutoReboot, which automatically reboots the phone daily at 3:00am for a few months now. I never really had trouble with my phone previously, it just seemed like a way to keep things cleaned out on a regular basis.
So about 1am I threw my Nexus on the charger with about 30% battery and went to sleep, this morning I get up and grab my phone and am treated to the screen stuck on, the battery at 6%, and the nice Google logo with a open padlock at the bottom of the screen... Holding the power button for 10 seconds or so powered the device off, and then I was able to power up and boot normally and within a few hours the battery was full. Tried a manual reboot and everything went fine.
First question... I am wondering is if this is just a fluke and it can be ignored, or is it likely the beginning signs that it's time to start looking for a new device? The phone is about 15 months old and never given me any problems at all.
Second question... Is rebooting daily really needed, would doing it automatically weekly or so be better, or am I better off just to manually reboot when something acts up or feels "off"?

Personally, I'd just randomly reboot it when you need to and not use some app to do it. Of course I mess with my phone a lot so reboot frequently, lol

Note 4 N910F dying when using when using flash on the camera despite 50% battery

Hi
I was wondering if anyone knows what is going on here? I was using the legendary CM12.1 and noticed that when I used the flash on the camera (affecting not just the pre installed camera but 3rd party ones) it would insta kill my phone. It wouldn't even turn back on without removing the battery. At the time, I put it down the rom itself however I returned to stock, full wiped and cleaned the cache, dalvik and complete factory reset and the problem persists....
When I check the battery graph, I notice it shows a dip from say 50% to 0 instanly and then back up, so I assumed this is a problem with the battery however the real mystery here is that I have now replaced the battery and its still happening. What do you guys think? Shall I send it back to the shop. Another bug is sometimes the phone drops from say 15% to turning off. Many thanks for any input

Here's a picture of what happens when I use the flash to kill the phone a few times
