Mobile Data turning off during standby automatically problem

I've been unable to get around this problem for the last few weeks now.
No matter what ROM my Milestone is on (It's the latest CM7 right now), it's been having problems keeping the mobile (2G/3G) data connection on, it seems lose connection every time the phone goes into standby.
At first I thought I was just losing connection to gtalk but I've caught the phone a few times coming out of standby with the data icon missing and then showing up a second later.
Other basic details;
I always flash the Singapore baseband from OR (which AFAIK is the same for Malaysia)
No battery saving apps
No Toggle2G use
WIFI has no data connectivity issues
I'm hoping someone can help me figure out this problem as it's a real killer to not get txts (gmail/whatsapp/etc), emails etc on-time

Going to try to leave wifi off for a day instead of a few hours for a better battery status screenshot but you can see what's happening in this one

In the period without wifi, and the period with actually, you can see I keep losing 3G/sync. This happens whether I'm moving or in the same location. Hell, it happens even at home.
Anyone think that flashing all the way back to stock froyo etc might help?
Are there any log files I should be looking at or posting for someone to help me with to figure out wtf?
I should also mention that this screenshot is from a FRESH flash of the latest CM7 from kabaldan, so I've ruled out (many many many times) that it's just a bad flash, or a bad rom (it does this on HO!NO!, FroyoMOD, milaq's cm6 and kabaldan's cm7 and probably others as well but those are the ones I've tried)
At this rate I'll get a new phone just for my sanity

I have the exact same problem with froyomod! help please!

update
I've flashed back to stock then to GOT 2.2.1 then to CM7 and it seems to have improved things by a lot on the first day. You can still see it happening however.

Looks like going to Stock -> GOT 2.2.1 -> CM7 has fixed my issue. More time needed but looks good already, I'm going to put down momentary loss of connection/3G as normal network issue rather than made by the phone now.
As you can tell, the last 2 screenshots have improved tremendously since re-flashing from stock
gosunta,
get on it, just follow the sticky'd posts.

I may have spoke too soon, it's still no good. New screenie in 6 or so hours to see if it continues.

Yep it's still doing it. It's worse when on the move and it obviously only notices its not connected/in-sync whenever I wake it up. I actually dropped the phone today and apart of me kinda hoped it would break so I could justify a new phone hahah .
Going to try going back a few versions of CM7 and see if that fixes it. Sick of this.

I had an idea a few hours ago of replacing the modded Talk (as included in Kabaldan's cm7 gapps or Ho!no! etc) for the stock one, so I went ahead and flashed gapps-gb-20110828-signed from the CM7 page.
Seems good so far over the last 2-3 hours, will report back in a day or two with screenshots. I hope this works. Also, if it does work I'm just going to go ahead and kill myself after all the flashing over and over of millions of roms (or so it feels hehehe)

There is no modding done to Google apps itself in the package I upload. Modding gapps is a bad idea, you would destroy the signatures by it, they need to match.
Only the updater script and app choice is modified.
Try to add this:
Code:
service dhcpcd_rmnet0 /system/bin/dhcpcd -ABKL
class post-zygote_services
disabled
oneshot
service iprenew_rmnet0 /system/bin/dhcpcd -n
class post-zygote_services
disabled
oneshot
to /system/etc/rootfs/init.mapphone_umts.rc like it can be seen here:
https://github.com/nadlabak/android...rebuilt/etc/rootfs/init.mapphone_umts.rc#L539
Let me know if it helped.
Btw., do you get connection to google servers at all when you switch to 2g only?

Hahah yeah I've just realised that your gapps isn't the issue, my bad kabs . It's still having the same problem now, lemme try your suggestion right now.
And yes, I do have connection to google servers while on 2g only.
edit in a few minutes.

Excuse the late reply as I've been busy but I figured it'd give me more screenshots of testing kabaldan's suggestion but...
Also note how the brown bars tend to correlate to when the phone is awake and even happening while the phone is awake.
It's still happening but I've noticed that the phone is at least capable of getting out of 2G and into 3G with some network activity which it has always done after sometime of use, get stuck in 2G and then I'd have to manually toggle it back despite WCDMA preference and no Toggle2G or Battery Saver usage.
I've noticed that I'm less likely to be disconnected from gtalk now though, it still happens obviously. My last chrome2phone sent link I waited 2 minutes with no response until I brought it out of standby and proceeded to use dropbox (thereby, I guess, it prompting to check connection to things...).
Kind of hankering to upgrade phones at this point but with the majority of phones being retail here and the fact that even a pre-order special of the Galaxy Nexus from my telco with a 24 month contract only results in saving less than 50EUR over retail, it would seem kind of stupid to get most phones still since everything is on the cusp of changing over the ICS :-/. Also STILL no droid3 here and I guess quite a few of us Milestone users love QWERTY like me

Same **** different day. Everyday. Going to now try updating to the newest CM7 and see if it still does it, been very busy (and disheartened by this issue as well) I only just noticed Kab's has 7.1.4 up.
I think I'm just going to start saving for a new phone

Have you tried using Toggle 2G/3G and setting 2G when screen is off? Yes, I know, it is not the solution, but, you would not gain anything using 3G with screen off and it would avoid this crazy 2G/3G/2G loop you get... I believe it is a decent work around.
By the way, in Brazil I got the same issue, only to realize that my phone carrier/operator is the one to blame, they have sold too much lines and their 3G connection is totally unrealiable due to that... When I saw that many of my friends were having the same issue with this carrier, then I've noticed that it was not the phone causing this issue... Perhaps somehow you are having the same issue, or, perhaps, someone build anything new between you and the tower causing this unrealiable connections (or perhaps you really have an issue). Are you sure you have flashed the proper baseband for your region? I believe CM7 comes with European Baseband (900/2100) which I believe is not the best for you....

The toggle2g suggestion might work, I'll look into it and see if it does it. However, I do think that I'm losing sync with g-chat even over 2G occasionally as well but I'll check anyway to be sure.
It seems to me that it specifically loses the data connection whenever the screen is off, as if its got a similar setting that it goes to sleep like "Wifi off when sleep". The actually annoying part is that when it does lose sync, it takes quite sometime before it gets it again (sometimes doesn't) or until I wake it. It looks like a loop but it clearly often matches against the Awake bars as well, ie the phone only noticing its not in sync (or 3g) when the phone is awaken.
Definitely don't have carrier problems, ruled that out as there's 3 others on same carrier at home without issue. Euro baseband seems to be the same thing but I always flash to Singapore anyway just to be sure.
I'll keep testing, I thought 7.1.4 CM7 update might fix this but it seems to be doing the same thing anyway . That reminds me that I need to try an older ROM and see if that helps.

kabaldan,
Any chance that if SU was denying radio permission that it would do this?
I've just noticed that in my SU logs radio keeps getting denied. In fact it has occurred to me that I haven't seen the Radio Allow/Deny SU screen every time I flash for some time now. I guess it gets stuck behind the setup-wizard screen and times out :-/
I'm reflashing to current CM7 right now and then if it happens again will Clear Data on SU and see if the radio permission screen comes up again and then check if its fixed my ****.

"Radio" asking for root permissions is Toggle2G.

Thanks for clearing that up for me kabaldan <3
I think I'm just going to assume my 3G radio is defective for now and put up with it.

Found this
http://code.google.com/p/market-enabler/issues/detail?id=116
Uninstalled it and reflashed.
Testing now. Looks good so far in battery stats.
EDIT:
Nope, not that either. OK I give up . It's definitely only doing it whenever it goes to Standby however. I've been running Sleep as Android lately to track my sleep cycles and it never loses sync when the screen is awake (the screen dims to minimum so that the app can track sleep, thus meaning the phone is always awake)

Any news on that issue? I'm having the same problem.

I'm having trouble with 3g and battery, my phone normally lasts for 16hs aprox with 6 hours of wifi and little / medium use, and I do not have a mobile data plan, so I never use it.
But, whenever I use 3g, my battery drops from 100% to 0% in less than 5 hours of almost "idle" and even with the screen off , it starts to heat like if I were playing Nova2 with a Walkie Talkie .
This is a battery problem or the mobile is not working properlly ?
Thanks

Bugs

Anyone notice any bugs so far with the one xl? If so, report them here. I'm getting some weird bugs.
Wifi issue 1: Sometimes when i leave a wifi zone the phone still shows its connected to wifi. Only way to get rid of it is to turn wifi off and then back on.
Wifi issue 2: It stays connected to wifi, however, i notice it jumps up and down quite often and doesnt remain consistent. Sometimes i loose connection at 0 bars and then it goes back to full.
Loading: Sometimes when i leave an application the screen needs to load and i get a "loading" notification in the middle of the screen.
SMS notifications sometimes don't notify me. I randomly have o check myself.
Facebook private messages don't notify me as well. I have to manuallty check. Even though its set to sync.
Sometimes my sim needs to re-register.
This is my second HTC one XL unit. Also, rogers cannot get lte to work on my device. Yes, i have an lte sim and my account has an lte plan. I just came from a sgs 2 lte.
Let me know if anyone else is experience any bugs?

Those are some serious bugs that would be a deal breaker for me. Hopefully it's just a defective unit and you could get it replaced?

Like i mentioned in my previous post this is my second unit!

I can safely say I have not encountered any of those issues yet.
LTE is working great (on Telus). No issues with WiFi. All SMS notifications are working. Haven't received any Facebook PMs yet, so not sure about that.
One issue I have noticed, though I'm not sure if it's with the device or with specific apps, is that some apps that have a dedicated menu key will still show the soft menu key at the bottom of the screen.
e.g...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Note the app has it's own menu key, yet the soft menu key is still visible.

I previously stated my wifi was fine, but I am starting to notice some issues with it lately. It seems to drop connection from time to time. Sometimes my SMS also will not notify me, or if they do, I won't have a flashing green notification led.
I was having a problem earlier saying something like 'Network access changed. Calling is restricted' and forced me to have no signal. Switching airplane mode on/off fixed this problem, and playing around with the network mode (gsm/hspda/lte) seems to have fixed this problem for now.

I get the same issue with the calling is restricted issue. Then it registers the sim again. Seems like we have some of the same issues. These issues were both persistent on both of the HTC one xl phones i had.

I wasn't sure if it was from a screw up of mine or not, but I've noticed Wifi drops as well. I think I've had some network drops too but never any dropped calls and it's difficult to diagnose as a certainty.
The wifi definitely drops though. Hope a custom kernel with better wifi drivers comes out.

Haven't seen those on AT&T's version.

I've been using my One X nonstop since I got it yesterday, I haven't noticed my WiFi drop even once. Though I'm connected to a 5Ghz network; I've switched to my 2.4Ghz network now and I'll report back with my results later.

Does the AT&T version have a different radio baseband or anything? Otherwise, the AT&T and Rogers are the same model (X325e).

i believe our model is PJ83100... i could be wrong on that though.

I have noticed the wifi issue. It's fine when I'm near the hotspot (say, in my living room), but if I go out onto my deck, a place that other phones have no issue with, it goes completely squirrelly.
Rogers LTE is definitely weaker on this phone than on the Samsungs. At work, I get one bar with this phone (sometimes two) when I'm on LTE. With my Note, I got 3 or 4. It doesn't seem to affect the speed at all though.

Bars mean nothing... check the signal strength in dB to do a fair comparison...

LTE has been fine on mine but again I am in Calgary and the Rogers coverage here isn't the best for LTE, so I don't get in the coverage area often but even without LTE coverage my device is pulling 12-13/Mbs which I am more than content with.
I have experienced some minor signal issues with Wifi but nothing worse than what I have experienced in the past with my Galaxy SII (I9100M). The only real bug I have experienced is in the official twitter app.
Each time I go to compose a tweet the screen sometimes glitches out for a second before the popup to compose the tweet appears. That is all I have found so far.

I don't think that's the correct number.
I've been looking into this over the last few days. After all the videos I watched and reviews I read, etc. I can only find two models of the One X. The HSPA/WCDMA "International" variant, the S720e; and the HSPA/WCDMA/LTE variant, the X325a.
Everyone in this forum should have the X325a.

The pj83100 is the number listed on the pre order
HTC
America
Inc.
PJ83100
WHT
PHONE
Maybe just the number used for pre order or something
Sent from wherever I am!

Ah, I just got the "no SMS notification" bug.
It happens when you leave the SMS app open when the screen is shut off. Even off, it assumes you're in the app and doesn't generate a notification.

That is how ICS (Android 4.0x) displays the menu button on legacy apps that have not been upgraded to the new ICS standards yet when being displayed on a phone with hard buttons like the One X. When a phone has the on screen buttons native in ICS (like on the Galaxy Nexus or some tablets) those dots show up as a fourth button on the bottom menu bar. Over time, as developers come into compliance with the new guidelines, I am sure the dots will go away or move to the top where they are supposed to be. I see that that app has a menu button up top but I would try something like Google Voice that is done "the right way" to see if you get the same result. For now though it is a monster waste of space.

I get the sms notification bug as well. And I think it happens not only when you have the app open and the screen off, but also sometimes when you're using the phone (and maybe the app is running in the background).
Also experiencing the black screen and re-loading when app switching.
One that hasn't been mentioned, is while typing, I sometimes get a "strobe" like flash of the screen. It flashes really brightly for a mili-second, and then back to normal. I don't think this should be confused with the "flickering" that so many people who have the international version are talking about. I'm using swiftkey, so I suppose it could be related to that, but I don't think so.
Hopefully all of these bugs are software related and will be taken care of with an update.

They seem all software related. Im of course experiencing similar issues! the phone still rocks! just some bugs need to be resolved. But nothing to hinder your daily use.

My WiFi/SMS notifs are fine, however as for Facebook, I've never had a single device that properly notified me when receiving a message, and therefore deem that a Facebook issue, not a One X issue. I've not had any problems with mine whatsoever.

[Q] Save my sanity! Wifi and data disables on screen off!

OK, let me first state that I have no battery saving apps installed, power saving is off and my wifi policy is set to always keep wifi awake.
Still, whenever my screen has been off for a few seconds (I'm guessing what happens is that the phone goes into deep sleep), both my wifi and my data connection goes into some kind of sleep state as well, making connections to and from the phone impossible. This means that push messages and mail aren't delivered and oftentimes when I turn on my phone again the messages start chiming in. Note that wifi and/or data don't need to reestablish after I turn the screen back on. They're still connected, just not active.
Using FTPServer on my One S and connecting from a pc confirms that all data sending (on both wifi and data) ceases after I turn off the screen.
When the phone is plugged in, all is dandy and all connections are kept alive!
I'm currently running running ViperS ROM, but this issue has plagued me across different ROMs (both sense and aosp) and across different radios as well.
I've literally (almost) googled my ass off on this issue, but I'm at my wits end. This shouldn't be related to HTC's SmartSync, since (1) I've disabled it in VenomTweaks and (2) It supposedly doesn't kick in until after 15 minutes. All my accounts have auto-sync activated and I've also disabled stuff like "restrict background data".
I've tried with and without the sleep mode settings under power settings below activated (w/ reboot after change).

For it to work the you need to use power saver so if you don't want it doing the other things then turn them off first then turn on power saver.

Now I'm on 2.15.0000 with radio 1.11.50.05.28.
I flashed the ICS RUU to do the official JB OTA in order to upgrade from my old hboot 1.14.0002 and radio 1.06es because I believed the old hboot and radio were the culprits in this. Sadly, they weren't.
To add insult to injury, I tried setting up a completely new google account as well as setting up a special hotmail account in the stock JB in case either of those were causing trouble with push message delays. Same crap though. Most nothing coming through until the screen was turned on.

Have you tried AOSP based ROMs as well? Made no difference for me, but YMMV...
But I agree that it's frustrating! It's 2013, everyone and their grandma are online 24/7 and I'm lucky if I get a mail notification within an hour of it actually arriving!

Yes AOSP ROMS as well. Resetting my router seemed to fix it as far as Wifi is concerned. Can't test data at the moment.

G930W8 Rebooting several times a day

I have a G930W8 that was supposedly brand new, running stock 7.0 with TWRP and SuperSU. It reboots 1-3 times a day at random times while I'm not using the phone.
I've factory reset it and only loaded a few apps on it, cleared davlik and cache, reloaded the stock rom from odin - it is still happening. Does anyone have any tips on how to diagnose? I've tried looking through the last_kmsg files but I can't make much sense out o them - should they be able to identify the cause for the crashing? I'm trying to determine if it's a hardware issue or something else.
I did have over 40k sms / mms messages on there that I'm clearing out now, would that cause spontaneous reboots?
Thanks for any help.

40k SMS could cause problems, but you said you factory reset, that would have cleared them

Thanks. I reloaded them after the reset with a backup and restore app. I changed the setting to only keep 1k messages on there now and will monitor.
Hopefully that was the issue, but really wondering if I will be able to make sense of the last_kmsg logs at all.
If the smaller quantity of messages on there doesn't resolve the issue, I'll try runnning it without an sdcard for a day. I initially suspected a problem with the sdcard, formatted it since - formatting did not resolve the issue.

Am I looking in the right spot? Since clearing out my sms messages, it still crashes on me every few hours. I pulled the last two kmsg files from the last two reboots. Is there anyone that can let me know if I'm looking at the right files to diagnose?
Is this area of the file telling me anything useful?

UPDATE:
I left the country for 8 days and was using a Costa Rica SIM card (and various different wifi connections) - the phone did not reboot a single time in 8 days.
On my first day back home, after putting my AT&T SIM card back in (this is a new card that I just got a few weeks ago from AT&T), and being connected to my home wifi - it has started spontaneously rebooting again. I've reset the network connections, it has not helped.
I'm torn between whether I got a bad SIM card that could be causing the reboots, or if it is something wrong with the wifi and my home network, or a combination of both. Many of the reboots seem to occur when I switch from LTE to wifi. It is a very difficult issue to reproduce.
Any suggestions on how to isolate the issue, any settings to check, or if it sounds like a radio or hardware issue?
Thanks.

I'm torn between whether I got a bad SIM card that could be causing the reboots, or if it is something wrong with the wifi and my home network, or a combination of both. Many of the reboots seem to occur when I switch from LTE to wifi. It is a very difficult issue to reproduce.
Any suggestions on how to isolate the issue, any settings to check, or if it sounds like a radio or hardware issue?
Thanks.

Yea, disable WiFi for another week, if it stops, it's the wifi, if it still crashes it's the SIM

Thanks. It just crashed again with wifi turned off, so that rules out that.
So it seems likely either a bad SIM, or the phone is having issues with the LTE network. I notice the network switches from LTE to LTE+ often.
It would be odd if it is a bad SIM as it is only a few weeks old, but I'll swap it out with AT&T.
Knowing that wifi is not an issue, any other suggestions other than a bad SIM? I'm also wondering if maybe the sim tray does not hold the hard well and it's loose.
Thanks for the support.

Just keep with your elimination technique, looks like you're almost down to the cause, be it SIM or LTE/+
Switch SIMs, if it doesn't crash when switching between LTE and + then ask your carrier for a new SIM

Couldn't a log file of some sort be run to trap/identify the app and error?

[Guide] Resolution to battery Drain Issue

Since OOS5.1.8 my OP6 battery was draining too fast...
things I have tried to stop this draining
Rooted and installed Greenify to hibernate some battery consuming apps like Facebook (5.1.8)- Still Draining
Clear cache in bootloader - Still Draining
Factory Reset - Still Draining
Using below tools I downgraded from 5.1.8 to 5.1.5
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892
And then updated to 5.1.6
Rooted and installed Greenify
Charged my battery 100% and manually off Mobile data with wifi ON

With mobile data on and wifi on ...my battery was draining as mobile data was causing Awake every time.
Since Mobile data turned off and WIFI on, I am getting good battery life :good:

What do you mean by untickmobile data? Is there a specific setting or you just manually turn off mobile data while using wifi?

Or what you could do OP is download the "full" 5.1.8 rom and flash that, along with TWRP and Magisk. Don't flash from the OTA update as this seems to cause the drain. Sorts the issue of battery drain for me anyway.

It was posted in the forum, I tried this also but draining didn't stop.

Wait... so how did you fix the drain? Because it seems that you didn't fix anything besides turning off mobile data? What if you turn off mobile data in 5.1.8?

I haven't tried this with 5.1.8....Turning off the mobile data was the thing that worked for me and one of my friend's 8gb version.

But then this isn't really a fix tho.... what if you have the same battery life on 5.1.8 with mobile data turned off? What if this isn't rom related but maybe your 4g connection? I have had this problem also on my galaxy s7 phone and after switching 4g off and turn on 3g is solved the drain but turning off mobile data as a whole isn't really a fix because what if you need to leave the house and have to use the mobile data.

There is no battery drain issues associated specifically with 5.1.8 but likely update files that never deleted properly after the update and this a lot of times causes a corruption. Just do a factory reset, or better yet, just install the full 5.1.8 full zip and you won't have this issue.
I'm getting 2% drain overnight (7 hours) and 10+hours of sot with about 36 hours off charge with 1.9%-3.4% combine drain per hour on 5.1.8 so certainly no issues with the latest update with battery drain. Only thing I do is turn off sync in Google account and just manually sync contacts and calendar when I make new entries and restrict background data on apps that I don't need waking the device all the time. I also turn off location permissions to apps that also don't need it.

Thank you for stating the obvious. But at least, you have the decency to provide some information. I see this kind of complaint a lot on the one plus forum (not xda) and everytime, the post is something like this : "I have a battery drain. Help me." What kind of help do they expect with zero information ?
