[Q] RILJ wakelock - are you affected? - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Hi all 7.7 users - Im a long time 7.7 owner and XDA lurker - having recently moved to Paranoid Android's CM10 based build for our tabs, ive noticed that the dreaded RILJ mobile network wakelock is back in full effect.
i have gone through the regular troubleshooting steps of enable Airplane mode, turn off, turn on, disable Airplane mode - this has no effect. other forums recommend using GETRIL to set up RIL properly, but that app does not support the 7.7 tab yet.
i am running a HK based p6800, which i had flashed the Austrian LQ2 stock rom on, before upgrading to PA 2.16. i do NOT have a sim card fitted at the moment, so i only use it on wifi - which confuses me more when i see the RILJ wakelock, because how is it locking on to a carrier signal without guidance from a sim card???
previous to this, Honeycomb stock was slow, but battery lasted for ever on standby, which was awesome. on ICS, performance decreased, but RILJ was not a problem. now on JB 4.1.1, RILJ never lets the tab sleep, and it remains on 200mhz until its battery dies a few hours later.
what are your experiences and suggestions? i have heard that some builds of CM10 fixed the RILJ issue, and i know PA has reached version 2.18 on other devices, but still waiting for it to be updated for our tab - however does anyone know if newer CM10 builds (supposedly android 4.1.2???) fix the RILJ wakelock?
thanks all

[Q] WiFi turning on by itself?

Hi All,
Having a strange issue with my Sensation wheras the WiFi is switching itself on at night.
Normally I will switch it off using the 'power bar' when I go to bed and then switch it back on when I wake up but since the Twitter update (on Orange which seems to have updated my market as well) it comes on by itself. If I turn it off again it stays off.
I know that both nights the phone has been about 7% battery and is in power save mode but this doesn't switch the WiFi off, just the sync. I then press the WiFi off and plug it into the mains.
Any ideas on why this is happeneing and if it is a known bug? Also if there is a way to fix it?
Thanks
Darren
Details??
Is your phone S-OFF?? rooted? If so, which ROM are you using? Please post all the details.
I had this bug twice with ICS, ma battery starts screaming at 21% while it was 80% just 2 hours before,it was wifi that was ON by itself

Sorry, standard Orange ROM, not rooted or anything

Seems to only have done it since the twitter update on saturday which also updated my marketplace.

Hi,
I have the same problem. In my case, I am using ICS4.0.3 on my Telstra HTC Velocity (rooted but stock ROM ).
I think it might be Juice Defender , but I'll confirm that in couple of days time.
I have used it once, and uninstalled it, but I think it might have left behind the settings (network scheduled to be turned on at night to sync).
I installed it again, and by default that option was turned on. I have now turned it off and uninstalled it again.
I shall let you know the outcome soon
i have this issue on my previous ARHD 6.6.0
i tried to flash with different kernel,it wont fix
all i do is flashed to New leedroid 7.3.0 the issue gone.
So i assume is ROM problem.not quite sure about this.
I think it was a problem with a specific base that was used (either in the stock or making the rom),
I had it on IC5.2 I think, but then updated my rom and it went away, it presented itself on all the roms that used that base (I believe) it should be gone now with the updated base that was released. Not sure of the specifics and version numbers, maybe a dev can provide if needed, but the updates shouldn't have that issue anymore

HTC ChaCha battery drain on CyanogenMod7.2

Hello,
the forum rules do not allow to post in "Development" section, so I am posting here.
I've installed CM 7.2 ROM for ChaCha from this Thread. (Build date: 20120824).
After reboot everything looked normal, there were minor lags, but since this was my first custom ROM, I assumed that it could be related to my performance settings (Governor: conservative CPU: 245 - 800Mhz). I've switched off all data connections (gps, mobile network, wifi) and disabled all animations to see how much battery it will consume in first 24 hours. To my surprise, the phone was off and battery was completely empty in the next morning.
I've installed CPU+Temp system widget to monitor CPU load. The widget showed that on idle system CPU usage was 98%-100% on maximum allowed frequency. After reboot the idle system CPU was normal - 1-10% on 245Mhz. Then I switched on Wifi and noticed that CPUusage started to increase. I've disabled wifi but CPU usage was up to maximum and didn't drop until reboot. I found that the same problem occurs with mobile network connection.
I opened Terminal and typed "top -m 6" to see which process is using the CPU. I found that system_server.so was taking up to 90% of CPU when the problem occured. "top -m 6 -t" showed that GPSLocationProvider thread of system_server.so was using all the CPU, in despite that GPS was always off.
I've started to search the solution of this problem and found this thread, which described that the problem is that librpc.so is not compatible with HTC gps drivers.
Then I've tried SuperOSR ROM and CM9 ROM. Both did not have this problem, which was interesting since SuperOSR is very similar to CM7.2. I've returned to CM7.2 and tried to solve the problem.
I updated the HTC drivers to the latest level (gps.chacha.so and others from the latest stock rom), but it did not affected the problem.
Then I did the binary compare of /lib/*.so between CM7.2 and SuperOSR and found that just a few libs was different. One of them was above mentioned librpc.so. I've installed librpc.so from SuperOSR to CM7.2 and the problem was gone.
The CPU usage now is 0%-4% when system is idle.
I hope that it will help others which is affected by this problem and I also wish that this bug could be solved in CM7.2.
can we use this metode for CM9?
HTC Chacha with CM9
This problem is not reproduceable on CM9 on my device. I believe you have different problem with similar symptoms. If you are experiencing 100% CPU load on idle device, open terminal and run "top -m 6" to find which process is using CPU and "top -m 6 -t" to find specific thread.
More likely you are running some widget which causes hang.
Thanks for the info! CPU usage was fixed to %100 before I did what you said! Thanks again :cyclops:

[Q] Wi-fi is not turning on in JB PA 2.52 by Bytecode

Well I have been using this ROM for sometime now, It is smooth.
The only probelm I am facing is the Wi-Fi is not tuning on, It is very irritating. It keeps on searching on the battery drains and keeps the phone awake.
Anyone else having the same prob??
Help me out, I tried searching the Official thread but no one seem to have that problem.

[Q] Random calls dropping.

Well, that's the problem.
I use wifi at home (5 bars) but when I'm off wifi, it's 4G. (5 bars)
At completely random intervals, using bluetooth, my phone will hang up.
I am running a rom (below) but no one else seems to be having the problem.
Is there a setting or something I need to look at?

If no one else is reporting similar problems it may be one of those instances where seemingly random problems occur after flashing a ROM. I would recommend booting into recovery and re-installing your ROM and seeing if that fixes your problem.

Hello all,

The problem cames when I use google maps GPS navigation, after I turn the apk off , turn the gps off etc, it consumes in stand by/deepsleep, 30-40mA ... if reboot the phone returns to normaly 1-5mA ,,, how can I fix this thing because I don't whant to restart my phone after every time I use navigation.
KK 4.4.2
Nobody has this problem? nobody has the solution?
This seems to be a bug for some 4.3 and early 4.4.2 users. Please refer to my other postings on this forum where I explain that the recently released 4.4.2 (175.44.1.en-DE) system version fixes the problem. (posting is called: "Just got OTA 4.4.2 (was 4.3): seems to have fixed it")
Let us know if you get this update and it fixes it for you!
