Hi. I'm facing the same problem. Wi-Fi drains the battery, but stays off when I disable it. Also, when is on, I don't receive notifications from apps (whatsapp, outlook, etc). No problems on mobile data..

I first install GearCM coming from stock LL firmaware, never rooted before. I have this issues so I make a clean install, like describe in post #3, but problem continues.

I tried to set WiFi Scan Interval to 300 and power saving management to 2 in synapse, but didn't work.

Apparently wlan_rx_wake is the one that keeps the phone awake (GSam battery monitor)

I will try to provide logcat, but first need to find out how to do it XD
[Galaxy S 4 i9500 Original Android Development] juan_rugge:
I just send you email with logcat..
[Galaxy S 4 i9500 Original Android Development] litvcom:
Did you fix it? Same problem here. I try modem I9500XXUHOD4, I9500XXUHOG2 and I9500XXUHPB1 but didn't help.
[Galaxy S 4 i9500 Original Android Development] juan_rugge:
Also, I think mediaserver keeps awake? I just test sound in loudspeaker and headphone for about 10 minutes (stock app) and after that when I check GSam, battery was going down, and "audio on" (in second screenshot is "audio encendido") keeps going up. it stop when force close music app. I took this screenshots, what do you think? I will see if I can replicate and logcat, now that I know how :)
[Galaxy S 4 i9500 Original Android Development] id0620:
No I cannot I still have the problem :rolleyes:

Random reboot streak

I got at least 3 or 4 random reboots everyday. Please look at my last_kmsg. Phone info attached in screenshot. thanks
[Galaxy S 4 i9500 Original Android Development] Anni SP:
To avoid random reboot the best you can do is reflash the whole rom by wiping everything and deny synapse root access dont use synapse its useless. ;)
[Galaxy S 4 i9500 Original Android Development] juan_rugge:
I try to replicate several times while connected to pc in debugging mode whit now luck.. but today i play some music on loudspeaker and some time after realize battery was going down, check mediaserver and “audio on” was going up, again try to make a logcat, but while it was running it, check mediaserver and saw it stopped.

I keep doing me stuff, and all happen again, but this time I only connect de USB and mediaserver stop the audio on time count..

The drain is there, and mediaserver go to the top of the list in GSam.. please tell me if there is something that i can do to show you this in a better way..

I will try to disable the stock music player and use google player.
[Galaxy S 4 i9500 Original Android Development] Forwuwenkai:
I just flashed this rom yesterday and i found something can't work well.

I was wanted to played the video(1080i+h.264+ac3),and it can't play on hw.Another ts file can't play on hw either.

The sound is lower than stock firmware

And charging is slow when I used the mobile on charger

Please fix this problems alberto96
[Galaxy S 4 i9500 Original Android Development] kaankkaraman:

[Galaxy S 4 i9500 Original Android Development] Alberto96:
If Charging is slow your Charger or USB Cable needs to be replaced.
[Galaxy S 4 i9500 Original Android Development] juan_rugge:
So about the wifi drain, after I make a cache and dalvik cache wipe, it’s been working “fine” for most of the time, but not consistently. I said “fine” because mobile data still consume less battery (and it should be the other way around, right?). About not been consistently, some time work “fine” and others not, I can clearly see that is draining. A reboot some times fixit. Synapse wifi power saving and scan interval is set to 2 and 300. Network notification, scanning always available and avoid poor connections are off. Keep wifi on during sleep: always. What about the Wiu2011Fi option? What is for?

About call quality, with XXUHOG2 modem it was veeery bad, I tried Indian modem from Gear 13 post and now it's so good like in Stock firmware. Radio signal also got better and more consistent (i live in Argentina).

I have a doubt regarding screen brightness and quick panel settings Behavior. When I unlock the phone, I can see how the brightness ramp up (more noticeable when is set to maximum) It happen the same if you quickly change from max to min and vice versa, brightness ramp up and down with a delay.

I have set 11 toggles in the quick panel settings. In the lock screen, one of them is missed (gps), but once the phone is unlocked, all 11 are there..

Are these things normal?

So far 2 reboots have happen, can’t remember what i was doing in the 1st one, i think setting something in sys ui (03/21), the 2nd (03/30) was when i try to open a video (wmv) in MX Vid Player, no problem after reboot.

Let me know if you need more info. The screenshot is from the best battery charge that i have so far :)
[Galaxy S 4 i9500 Original Android Development] Sm007hCriminal:

[Galaxy S 4 i9500 Original Android Development] NishenR:
After suffering from very slow charging, I had done tests with different chargers and cables (using the current monitor in synapse). The cables i normally used were 100% the issue. Input value for old cables were 400-600mA as opposed to 1700mA for a good quality, new cable.
[Galaxy S 4 i9500 Original Android Development] MoreTissues:
Yup...absolutely right....so for those complaining slow charging...this mate here have a good point...=)
[Galaxy S 4 i9500 Original Android Development] Toxxsin:
I've got the same charging issue.

Charging on MBP rom is Ok, and charging on GearCM is notably slower. Do you think the problem is in cables?)
[Galaxy S 4 i9500 Original Android Development] MoreTissues:
charging slow or fast depends on ur USB cable..and also the place where u plug it...
[Galaxy S 4 i9500 Original Android Development] Toxxsin:
Ok.

I've used same cable, same charger and same power socket. Different ROMs. Thought it would be obvious though
[Galaxy S 4 i9500 Original Android Development] marianomd:
Phone restarts after low battery turnoff resulting in bootloop

I have this exact same problem. My phone restarts after shuting down itself because of low battery, That results in a bootloop and data loss.

Nobody else having this issue?
[Galaxy S 4 i9500 Original Android Development] asad007:
Only the first part happens to me

But I'm on a non stock kernel
[Galaxy S 4 i9500 Original Android Development] kaankkaraman:
No slow charging issue, charging finishes about 1hour 50 minutes.
[Galaxy S 4 i9500 Original Android Development] Sm007hCriminal:
Try a different cable.

I had the same issue and i fixed it by using a better cable.

[Galaxy S 4 i9500 Original Android Development] Alberto96:
Yes
[Galaxy S 4 i9500 Original Android Development] Eddie_53:
You are good if it is just these issues... Here sometimes the phone restarts randomly (with 40%, for example) and then when it boots up it is on 5%... I was getting crazy with this. I hate it but I'm back with stock T~T

The low headset mic and the random reboots make it impossible for me to use the ROM. It is awesome but these bugs freaks me out
[Galaxy S 4 i9500 Original Android Development] asad007:
Calibrating your battery may help
[Galaxy S 4 i9500 Original Android Development] Eddie_53:
Here comes the worst... I've done it. I think it might be the battery itself
[Galaxy S 4 i9500 Original Android Development] asad007:
It could be that your battery is swollen

Test whether it's swollen or not :

Put your battery on a flat table and try to spin it , if it spins it is swollen otherwise not :p
[Galaxy S 4 i9500 Original Android Development] SalimPS:
yeah You're not the only one who face this problem.. I also face this random reboot bug then it reboots with 3% or 5% down from 50% or 40% .. but it happens only after I flash the rom for the first time .. when i discharge the battery and recharge it again it goes back to normal. this bug never happen to me in stock rom so I'm sure its rom related.
[Galaxy S 4 i9500 Original Android Development] Alberto96:

I look his kernel commits and he added gpu overclock and thermal driver changes included. I think it will be included in performance profiles.

Having used your rom for some time , I can say its simply great with almost no bugs and working like stock cm .

The only two issues I faced were

1 . Huge battery drain .

2 . Slight crackling of sound .

All else is fine . Looking up to a new release from you to solve the battery drain problem .

P.S. I do a clean rom install and not a dirty upgrade . Thanks .

Sent from my HM NOTE 1LTE
[Galaxy S 4 i9500 Original Android Development] rbaker91:
I finally decided to upgrade from CM12.

Well, im a lot happier with this build.

No google play service FCS, no audio disappearing so far, camera is fine. No random reboots.

The only thing I noticed is that when I'm playing songs thru Bluetooth the phone gets a little laggy specially when unlocking. I was on spotify, haven't tried other apps yet.

NO BATTERY DRAIN, if anything its better than cm 12.
[Galaxy S 4 i9500 Original Android Development] active0:
Only bugs I noticed are

1. Phone switches to emergency calls only randomly

2. Bluetooth a bit laggy

Edit

3. Hardware acceleration errors when playing video from my media server ... on every video ...end result videos won't play

Will these be fixed in next build ?

I think that's all I noticed. .. battery life is great ...
[Galaxy S 4 i9500 Original Android Development] Alberto96:
New build is up!

Important changes have been made.

Wifi killing the battery

there is a problematic bug I face everyday while using this rom..

an Example this morning my phone was 100% at 8:30 I left it on the table sitting not even connected to wifi and it died at 11:00

it's caused by wifi, i tried all the suggestions that people suggest but no luck.. any help please?
[Galaxy S 4 i9500 Original Android Development] mukeshbaidwan:
Turn off wifi scanning in location menu.

If still not fixed try toggling airplane mode on/off.

If still not fixed, re-flash ROM.

Currently using kikat TW. I am huge fan of Alberto's work but MM build still needs some ironing. I just cannot stand the reboots and the drain. Desperately waiting for a stable release. Hopefully he does his magic soon.
[Galaxy S 4 i9500 Original Android Development] marianomd:
I finally resolved almost all the problems flashing latest stock CM12.1 (cm-12.1-20160424-NIGHLTY-i9500.zip)

1) Battery consumption is much, much better (yesterday it went from 100% to 50% in 17 hours!!!) before it didn't last more that 8 hours to 0%.

2) No more bootloop when low battery

3) Mic volume resolved and no more distortion

4) Camera is working perfect, no more crashes

Only problem is bluetooth phone calls. (robotic/pitched down voice) which I'll have to accept for now.

Only one thing I'm missing is Synapse and it's max charging current tuning.
[Galaxy S 4 i9500 Original Android Development] cheviahmed:
i tried (cm-12.1-20160424-NIGHLTY-i9500.zip) ... this official nightly latest one. flashed it last night and its pretty good. Battery life on this is far better than any aosp rom right now for our device. i suggest you all try this one.
[Galaxy S 4 i9500 Original Android Development] invincible authority:
Bro. Is there any custom kernel available for official CM?
[Galaxy S 4 i9500 Original Android Development] cheviahmed:
[MENTION=4166346]invincible authority[/MENTION]. There is LWK kernel in the i9500 Android Development section , which only works for gear cm. But if you're using this latest cm nightly, going with the stock kernel is the best choice. Good performance and Battery life.

hello,

i have a few questions:

are you still using this version and if you are, are you still pleased with it?

can you share the nightly version you have (24.04)? i could not find it in cyanogenmod website.

did you change the kernel when flashing this version, which kernel do you use?

do you have any call echo complaints from the people you are talking?

about modem and bootloader, which ones are you using?

thanks.

if you somehow still have this version of the rom, can you please upload it to cloud and share the link?

Due to my limited available free-time, i need to abandon this GearCM 12.1. Please switch to GearCM 13 if you want to keep your device updated.

Goodbye Lollipop Users, see you, maybe, on Marshmallow!

So far everything working ok for me on latest build, apart from a random reboot after screen froze in google plus app, last_kmsg attached below.

Was a full wipe clean install, latest delta gapps and my usual apps restored.

Thanks again for your ongoing work for us i9500 owners :good:
[Galaxy S 4 i9500 Original Android Development] zozoz13:
Just try latest build a few hours ago, so far its running smoothly with Nano modular Tk-Gapps. This is my review for the latest build:

- Not yet experience random reboot until now.

- Not have excessive heat until now (Overheating problem seemed to have been completely resolved)

- Audio disapppearing bug still here. I just tried to reboot 3 times, and every reboot audio is gone. I have to make a call to fix it.

- LED light not as bright as TW ROM. But this is better than before.

- Charge current when screen on can't be changed, even i've set it in Synapse. It follows the Charge current when screen is off.

- Camera works flawlessly! I try to stress it alot, still working just as normal. And i've not found "Camera can't connect" Issue yet.

Just above the bug I found. Still looking for new bug. Other than that, the latest build is more stable,smooth and not as hot as the previous build :good:. This is the best GearCM build ever than any previous build :good:

[MENTION=2386505]Alberto96[/MENTION] Can i make a request mate? Can you underclock the CPU at 200mhz (Or 100mhz) for more better battery usage when Idle? If you make it happen, i'll be very grateful :)

Thanks alot for your Hard Work :good:
[Galaxy S 4 i9500 Original Android Development] Alberto96:
New build coming today with CPU Overclock/Underclock (A7/A15), Wolfson Sound Control and Screen Control. (200MHz A7 frequency...1800MHz A15 frequency...Headphone Amplifier...Speaker Equalizer...Gamma Control...Anti-Smearing Workaround...and much more).

Oh and most important, fixed Speaker Volume :) (no more horrible distorted sound).

Was just about to download the rom and I read this :D

I can definitely wait for a few hours

Waiting impatiently

Also please add option to increase charging current

I like 1900 mah even when screen is on

1200 seems too less
[Galaxy S 4 i9500 Original Android Development] Alberto96:
Yes :)

Unfortunately nothing wrong is in the log except sound card crash :/

1) Nice

2) 2x Nice

3) Unfortunately yes...

4) Kernel Feature

5) Uhm...i'll take a look at iy

6) 3x Nice :)

Hahahah. I hope that won't return to TW anymore after the upcoming release :P

Man, 1900Mah while the screen is on means "BURN YOUR PHONE". Synapse has already all the settings to manage it, but do it at your own risk.
[Galaxy S 4 i9500 Original Android Development] rgshah3:
Have been using 1900 mah for almost a year now [emoji14]

Once the battery drain pr oblem is corrected I will switch from Tw to Cm . As gear cm is the best cm rom for i9500 .

Then no going back to Tw .[emoji2]
