Yes this is the "heat" issue, at least for me: screen off, phone in pocket doing nothing (but Wi-Fi on, so some syncs in the background). Phone get lukewarm (not hot), loose 50% battery in 2h, cpu clock too much in the 1Ghz region and too little deep sleep, battery used mostly by kernel and cyanogenmod system.

Doesn't happen all the time, but just after a reboot cpu stay at 1Ghz much too long. It's normal it scales up for some init/service launch but then why not all the way up till 1.8Ghz? After it settle most of the time, but the heat issues looks like the phone is back to the just after boot strange behavior...no exposed here, the latest banks gapps, dirty flash...

Seems like we go for other kernel.I don't know.I am in a dead end
[Galaxy S 4 i9505 Original Android Development] gkai:
It's strange cause it did not happen 2+ releases ago...and I think the kernel was the same, no?

Btw, I'm using extreme battery profile now, and after the initial crazy after-boot behavior, it seems much better...I will stay on default extreme battery and see what happen in the next day...

İm waiting for your experience. but i think cpu load issues are not stweaks or kernel problem. i think its RILJ and cyanogenmods system or android system problem. so its not kernel my desicion.
[Galaxy S 4 i9505 Original Android Development] gkai:
You may be right, or a kernel/cyanogen system interaction: those are the 2 heavy battery users that are reported when heat issue is present, and afaik issue started 2 releases ago with an unchanged kernel...maybe some recent change in cyanogenmod system do not play nice with alucard kernel?

Atleast i am not the only one.

Even with jdc aosp i experienced this.

I was watching youtube and a minute later or so the cpu temp started to crank up andy s4 started to lag. Thats why i decided to come back to my current rom now. All google account sync is off even yahoo mail sync is off. ( i dont sync my email ) i do it manually.

A small request. For those who are having cpu load problems. ( when idle )

Install this app

A just use your s4 for atleast 10-20mins and post a screenshot like this. ( use it normally )

Why every time I reboot the phone icon LiveDisplay / Ambient Display appears on the notification bar ? I remove it manually , but when I reboot , it appears again ... Any idea?
[Galaxy S 4 i9505 Original Android Development] sjamie:
My phone rarely overheats but when it does, a reboot seems to fix it for a very long time. Therefore, it doesn't bother me too much compared to all of the goodness I get from this ROM.
[Galaxy S 4 i9505 Original Android Development] Creeper36:
I just picked up my phone from being idle for the last 20 mins and this is what it shows.

*Note that running the app to display the temp also added to the temp :)
[Galaxy S 4 i9505 Original Android Development] sjamie:
Under consistent use, my battery normally drains at approximately 20% per hour which usually nets me close to 4 hours SOT. Of course, standby time on this thing is a BEAST!

If you can, after the Kernel Fix, can you add lock screen shortcuts?

Like this:
[Galaxy S 4 i9505 Original Android Development] Creeper36:
I know if I play that game that my phone will become really hot, really really HOT! Thats like playing CALL OF DUTY for the PC on Max Framerate and Resolution.. IT WILL BE HOT!

I am trying to determine if you're on IDLE, as in not doing anything, what the temp is.

IDLE TEMP!

Are you running any App Killers or Hibernators? Is your governor on Max Performance?

=========================================================================

MY TIPS:

* After your initial setup you need to tweak a few things:

= Settings > Location > Change to 'Device Only'.

= Settings > Location > 3-Dots > Scanning > DISABLE (untick) Wifi Scanning and Bluetooth Scanning.

= Pull-Down Notification Panel > GPS (Device Only) changed to disabled.

= App Drawer > Google > 3-Lines > Settings > Now Cards > Turn OFF

= App Drawer > Google > 3-Lines > Settings > Voice > OK GOOGLE Detection > Turn OFF

Then I install "Clean Master" and "Greenify" and Titanium Backup Pro

Clean Master is used to block startup apps and kill active apps before I turn my screen off.

Greenify is used to hibernate apps that I cannot block and kill (Facebook and Messenger).

Titanium Backup Pro will Freeze a lot of system apps from even starting up to begin with. I freeze about 12 system apps with this.

Its a trial-and-error with figuring out which ones I can freeze and which ones I cannot. It took me several days to tweak everything. I can now get 5 days of battery life at IDLE ONLY. NOT USING MY PHONE. ITS JUST SITTING ON MY DESK. Now everytime I use it I get battery drain.. I get 24 hours of battery life with moderate use. You determine what your moderate use is. If your playing extreme games with lots of CPU calculations then I suspect you get 3 hours of battery life and LOTS OF HEAT.

My average CPU temp is about 75-77 while IDLE.

[Galaxy S 4 i9505 Original Android Development] sjamie:
If you are using the app Gas Buddy, switch to Gas Guru for more stable Bluetooth performance. Since I've made the switch, I've only experienced the BT Share crash once in the last week instead of 10+ times per day! That is the only change I've made.
[Galaxy S 4 i9505 Original Android Development] markiarom:

i didnt say that.i just say that every update of rom is actually waiting new kernel updates.

if alucard does NO changes to kernel i dont release a new update.no reason for this
[Galaxy S 4 i9505 Original Android Development] markiarom:
EDIT:

Rebooted, after first reboot due to BT crash, due to CPU stress, now no CPU unusual usage.. So reboot solve this issue, however i can't say it'a a great solution, but it's the only one for me

[Galaxy S 4 i9505 Original Android Development] Auron91:
I'm still using the 29 march release. look at the screenshot, last night the battery discharged completely, and the phone was in airplane mode..
[Galaxy S 4 i9505 Original Android Development] gkai:
Yes let's hope feedmeeee solution works, or side/alucard find what's causing it. For now, using feedmeee+stweaks extreme battery it's working well, after the initial reboot crazyness...but if this happen even in one every ten discharge cycle it's difficult for me to keep the rom my dd: you can end up with a dead phone at very inconvenient times...

No, this is something I should try next...but others with clean install have reported the same heat problem, so I prefer to wait.

Good to hear. Are you a moderate user? Just Messaging/Whatsapp/Calls?

A lot of the heat issues seem to be with heavier users
[Galaxy S 4 i9505 Original Android Development] gkai:
Not so sure about that, I'm a light user, no games, basic use, i'd like to get as much battery life as possible without ui lags. But the heat issue I suffer is not during heavy use (3D game, GPS navigation, ...)...it's the phone not standbying correctly. Phone getting warm in pocket is a good description of my heat issue...and it's the same for most people having "heat" problem afaik.

I was using 0510 with bank gapps for days without any problems (I use BT only for calls, its working well even with ok google active).

Since today I cannot disable "do not disturb" anymore. It was configured to stay active until next alarm.

The only thing I did differently was disable the alarm before it triggered.

Rebooting, as expected, doesn't solve it.

Where I can find this control in settings?
[Galaxy S 4 i9505 Original Android Development] :
So Side here are the issues i have.

The setting in the charging section of stweaks that says limit screen on charging current is set to enabled but when screen is on the charge current is not limited. like it should be. stock rom does this, charging current drops when screen is on. This setting not working causes phone overheating while charging and using. Gsam shows battery temperature of 110 F and phone gets very hot. i have manually set to 1000 mah.

i have set sd card as internal and moved apps to it. after a reboot. the shortcuts on the launcher of the apps on the sd card dissapear.

i use greenify with aggresive doze and no apps hibernation.

---------- Post added at 06:22 AM ---------- Previous post was at 06:18 AM ----------

And for the for the heat issue that people are experiencing, Why not use the stock throthling temperature? from stock rom.

Is that possible to get the values?
[Galaxy S 4 i9505 Original Android Development] gkai:
Thermal throttling can not solved the "heat" issue, a better description would be "phone warm when idle". It's more warm than really hot, and cause a very low battery life when it happen, like phone empty after 4 hours...

Other people describe another heat issue: phone get extremely hot when playing demanding games...but this is a different problem, there thermal throttling may help but would reduce FPS so not sure...the second issue does not affect me, I'm not a gamer, and it's more app specific anyway...

Just did a clean install with absolutely nothing but banks gapps. So far no heating issues.

The S4 is just for me to muck around with, not my DD so I don't know what the regular usage would be like.

If anyone has a CPU usage or heat logging tool to suggest I can install & leave idle for a day or two.
[Galaxy S 4 i9505 Original Android Development] markiarom:
IMO is really nosense to use a smartphone without apps..
[Galaxy S 4 i9505 Original Android Development] skynetau:
Not the point. Trying to see if it really is just a problem with kernel/ROM causing idle heat or if it is due to specific apps running in the background ramping up CPU clock speed and the phone not truly being idle.

Edit:

So far no battery drain or any heat on standby. Is taking a very long time to wake up from sleep though.
[Galaxy S 4 i9505 Original Android Development] Der-Knuffi:
I think, your test is wrong. When the JDC AOSP did heat up my phone, it was right after using some apps (different apps, not always, just sometimes when using them, no pattern visible) and putting it back into my pocket. Or even when it was already in the pocket for quite a time.

So please take it with you, move it and use it.

After almost 2 days on extreme battery profile and feedmeeee blacklist of battery optimisation I must say that phone behaves correctly, not heat in pocket for now, and not much heating when using the phone either.

Very odd. BT is now working on the S4 flawlessly. I've only used it on my UE BOOM speakers - played music, made a call and no crashes or hiccups. It transitioned from call to music and vice versa normally.

Battery life is also A+.

I was getting BT FCs before on this exact same build. IMO side and JDCTeam are incredibly close to having a stable MM ROM.

Nice work fellas.
[Galaxy S 4 i9505 Original Android Development] protoplasm:
First of all thanks for another great rom from you guys!

I had a problem with the fast unlock lockscreen feature. After enabling the feature and locking my phone via the power button i was unable to unlock it with the right password. Interestingly a reboot would work until the second time the password was entered. Even though the startup decryption was successful the phone would not unlock. Since after a dirty reflash the problem persisted i played around with the screenlock. Turns out the 'sloution' for my problem was, entering the correct unock password, holding the done button until the screen started to turn off due to inactivity and releasing it in the right moment.

I disabled the fast unlock function and had no more problems with the screenlock ever since.

I experienced heat issues which were not traceable from my perspective. The phone started to get warm in my pocket and the battery went dead after about 5 hours idle. The battery screen showed no apps using power however awake was active the whole time.

I suspect the problem to be related to the gps app 'Osmand' downloaded via fdroid and its wakeup feature but cannt proof it. A restart solved the problem every time so no complain from my side. My phone does get a bit warm during normal usage though but the battery life is amazing in comparison to any other rom ive used before.

Maybe this helps someone

thanks for all the great roms again! :good:

Just a quick update: phone got really hot when plugged during an episode of network instability: switched between multiple Wi-Fi networks and LTE continuously...so it may be linked to radio/rild indeed...

Mine has OptCM from day 1... his is still stock and updated with Official TW... well... our phones are working phones... my colleague has many calls that are without audio on both sides... my phone has this problem only few times in a week... Anything to think about?

For me it happens only since MM roms, I've never noticed that before. Not a big pb regarding my use (there's a workaround, even if not very usefull), I don't want to go back to CM12.1 or TW (thanks for the feeback about the same pb in samsung roms) so I stay in MM that offers a new life to my phone.

I didn't know it also happens on official TW. WoW!
[Galaxy S 4 i9505 Original Android Development] smeroni68:
I hope it's clear from my post, that my colleague has Lollipop TW 5.0.1 stock, and the problem appear more frequently to him than on mine... what to learn about this?

1) It happens also on Original TW (LP)

2) It happens on OptCM13 (MM) but seems less frequently

3) Our two phones are "twins brothers", born at the same time... and they have 2 years age

Normal warranty from Sammy will cover 2 years for the HW... that's the expected life time from the producer that would like (for sure) to sell new phones.

Probably your feeling about "it happens only since MM" it's falsed by the point 3 I wrote: our phones are becoming older, and as for ourself the age brings some "bad news" day by day... I'll be not surprised if you come back to original TW or any rom you evaluate as stable and after some time and randomly in a call you will miss audio... before or late, our hardware will die (due to age) or by an accident (like a fall down). That's life!
[Galaxy S 4 i9505 Original Android Development] walttheboss:
Its a nasty problem. I now have App Ops installed and removed microphone permission from google app. Have not had the issue in weeks. I am still on DU lollipop (see below)and patiently waiting till mm is more stable.

There is a permissions issue/battle between WhatsApp, Skype, and the phone. Was for me. One or all would break. Skype got one call and then nothing after till a hard reboot.

Could also be a hardware issue. Samsung has this nasty habit of making ten models of the same phone. In the factory who know how those parts get scrambled!

Hope you get it worked out. No good having a phone you can't call on!
