Hi again,

PACman is even worse. First off all, the UI is laggy as h*ll; sometimes, it takes more than two seconds for a button touch to be recognized.

That would be somewhat tolerable if the battery life was better. But in 2.5 hours of leaving the device lying idly on my table (display turned off), more than 50% of the time, the phone was active. BetterBatteryStats are again included as an attachment; perhaps someone can find out what the problem is with them. At least, this kernel doesn't hide the xmm_baseband wakelock, though I have no idea what that means whatsoever.

This is getting ridiculous - is there really no way to get the phone to last more than ten hours (doing nothing with it - when I use it even for occasional browsing/e-mail checks, it's way less than that) anymore? Why is no one else having problems on that scale? :(

Typing this post cost 3% of my battery. And I'm typing it on my computer, not on my phone.

Depressed greetings, Pit.

When i watch your battery stats its your wifi did your try to install then wifi update of demetris? Try then samething with your wifi off i think it would increase slot of your battery
[LG Optimus 4X HD] blavov:
Thanks, for the info, I will investigate that, though I haven't found this "wifi update of demetris" on first Google try yet, just recommendations what to do with your WLAN router and PC settings.

But I my second-to-last try - where I was out shopping - the wlan_rx wakelock wasn't the problem, rather the xmm_baseband wakelock, where I still am clueless as to what that means at all. I fear that getting rid of the wlan wakelocks wouldn't help my general problems, just the problems I had at home last night in my last try.

Furthermore, if I can use the phone only by carefully switching off and on wlan manually whenever I leave the house, the phone will become pretty much useless to me. Yesterday alone, I forgot switching wifi back on twice. That way, either notifications would go through mobile data connection or not happen at all.

I will reflash my device again this morning - as the PACman UI lags are unbearable for me - and see what I can do about the wlan drain. I cannot reconfigure all the wifi networks I connect to, as some of them aren't mine to configure.

Look in the seccond post your will zee a long story but at then and of that story you see 3 zip files flash then then nvida 4.3+ broadcom driver update by cwm dunno if it solves your probleme for me its great

Goodluck

I don have any problems with liquid rom. Also I flash gaps imidiatly after flashing rom without reboot. Try flashing 4.2.2 android it is better for our prone then 4.3 builds.

Sent from my microwave.
[LG Optimus 4X HD] blavov:
I tried that earlier today, and the LiquidSmooth 2.9 (Android 4.2.2) installed fine by your instructions. But it didn't help at all with the battery usage. Phone is running on conservative governor limite to 1 GHz, and I even tried the Broadcom Wifi Update mentioned here earlier (otherwise, I'm on the LS standard kernel).

It all doesn't help, the BetterBatteryStats are still full of wlan wakelocks (even though I switched to static IP as someone mentioned that might help). Result: 10,8% battery drop per hour of leaving the phone with display off on the table.

Before I flash another ROM for the 14th time this weekend, I will collect some results with wifi turned off. Not that that would be a feasible option for me, but I want to get to the bottom of this.

Cheers, Pit.
[LG Optimus 4X HD] blavov:
Hi again,

I disabled wifi, and the loss went down to an acceptable 3% per hour.

Then disabled everyting IPv6 in my house (confirmed it with tcpdump - zero packets), and turned wifi on again. Result: 11% loss per hour, as before. 55% wlan_rx wakelock. :(

Is there really no way to use this phone in halfway normal environments? After rebooting the device more than 50 times in the last 36 hours, and flashing 14 different combinations of ROMs, I'm out of ideas. If I can't use the phone without disabling wifi whenever I'm not connected to a power supply, then this phone is about as useful as a brick to me. ;(

Sad, Pit.
[LG Optimus 4X HD] dimi89:
10% drop per hour is .. O.O you should test your battery helth.Hows your battery life with stock rom and stock kernel ?
[LG Optimus 4X HD] biggoof75:
I also had a huge amount of wlan_rx_wake s .. I found out, that a lot of broadcasts in the net were the reason. ARP for example.

I created my own network for the 4x which got routed to my main network and voila .. No extreme battery usage anymore..
[LG Optimus 4X HD] blavov:
Well, it was fine two months ago, before I started using Custom ROMs. It was fine the first month of using custom ROMs, too.

I haven't tried any stock ROMs since flashing CM 10.1.2, so I can't tell you how battery life would be now with them. But as the phone is awake most of the time even when the display is switched off, I somehow doubt it is a battery health issue.
[LG Optimus 4X HD] dimi89:
9 hours not touching my phone and I have 7% battery drop i am using latest demetris liquid build wifi is always on data is off (when I am using wifi I turn off data). Sometimes I get a lot of draining but 90% of time it is normal. Before locking device i always use built in task manager and close apps. Will provide screenshots as soon as I get them to work. And I think I can get even better battery life with premium greenefy app since I can hibernate system apps.

[LG Optimus 4X HD] blavov:
I still use the Liquid v2.9 (the last Android 4.2 one) - I'm unable to reflash the phone during the week as I have to work and be able to use my smartphone. However, I have found out two other things:

On my drive to work (when I leave the phone in my pocket unused), the battery drops only about 1% per hour. I had a totally different experience while out shopping last weekend, where the drop was about five times that much, but that was using CarbonROM.

I found two broadcasts in my home network; one was a Samsung printer which inquired about an IP address every three seconds (while already having one), a switch to static IP solved that problem. The other was caused by DropBox's LanSync function on my Desktop PC, which searched every 30 seconds for compatible devices. I turned that off as well.

Unfortunately, the drop at home remains unchanged, even though I have now exactly zero broadcasts whatsoever in the LAN (verified with tcpdump running 125 minutes catching 0 broadcast packets). it's still 9,2% drop per hour, with the phone being awake 77,1% of the time, and 53% of the time, it due to wlan_rx_wake. BBS logfile attached as usual.

I will try and test tomorrow how the phone fares at work (where I usually keep the phone plugged in). The phone uses wifi there, too, but it's completely different hardware. But at home, I exhausted my last testing options. What keeps my phone awake for so d*mn long?

Still no progress, Pit.
[LG Optimus 4X HD] blavov:
Hi all,

a few updates from my daily experiences with battery drain:

Today, I repeated my last home phone tests (leaving phone untouched for an hour or more) at work, where the phone also logs into a WLAN very much like at home. The drop was only 3.6% per hour - still considerable, but way lower than the 10-11% drop I get at home in very much the same conditions. Bear in mind, there are no broadcasts and no ipv6 packets in my home network, as I disabled them all.

While I'm driving to/from work to/from home, I don't get much battery drain anymore. At least in that respect, flashing almost every Custom ROM available for my phone paid off, as I had a 10% drop per hour "in the wild" (no wlan connection) when I was testing CarbonROM last weekend.

But at home, nothing seems to help. dimi89 suggested to me I should deactivate 3G when I'm connected to wifi, remove the SD card and try again. I was skeptical that that could remedy the problem, and to be sure, it hasn't helped one bit. 9.3% drain per hour, almost the same as before. The phone was 74,1% awake and spent 50,4% in wlan_rx_wake wakelocks.

BBS log files are attached.

I there anything else I can try?

Feeling like Sysiphos, Pit.
[LG Optimus 4X HD] spamcakes:
Not sure how tcpdump works but you could try Network log:

https://play.google.com/store/apps/details?id=com.googlecode.networklog&hl=en

Or Shark for root if you're feeling really smart and courageous, I couldn't fgure out how to use it properly but it does seem to provide the most detailed capture of network traffic.

https://play.google.com/store/apps/details?id=lv.n3o.shark&hl=en

I had/have the same problem with my phone, although it's less than it used to be after finding out what was happening in network log.

My family's various laptops and smart tvs were sending ARPs and Netbios things god knows how many times a minute, it got a lot better after using iptables in the router firewall to block traffic on the ports that were sending requests but still about 4-5% per hour drain on wifi.
[LG Optimus 4X HD] biggoof75:
As explained above I experienced the same behavior (ARP, Netbios and other stuff)

ARP is nothing you can disable because it is the way IPV4 works.. A static ARP table might help but decreases flexibility.

I found the broadcasts using wireshark on a PC in the same IPV4 adress range as the phone.

As already mentioned I created a wifi network segment only for my phone in my openwrt router..

All Google data transmissions have been disabled (google now, tracking, ....) in my 4X.

With CM10.1.3 and Optimus Prime 2.7 I can get a drain as low as 1 - 1,5% p.h. with light usage of course.
[LG Optimus 4X HD] Flying_Bear:
did you check how wifi acts on stock rom? if it works properly, it seems to be much more efficient to go back to stock or stock-based rom & debloat it yourself.
[LG Optimus 4X HD] Kwiatek87:
As far as I remember when I get rid of official LG rom and install CM + flash Optimus kernel I got terrible wakelocks (about 95% awake, % deepsleep). Reflashing another roms and kernels did not help. But "luckly" due to my customisations I get bootlops which leeds me to necessity of flashing my phone with standard (original) rom using CWM (there was no other way I can't even get to my bootmanager). After that and flashing again CM, problem with battery drain disapered. Of course I don't mess again with custom kernels.

So if You know how and You are not scared of loosing data try to reflash standard rom by CWM. It helped me and I'll helps You.
[LG Optimus 4X HD] spamcakes:
Tbh I don't see anything in that log that would result in excessive drain.

All the usual suspects are very quiet.

How's the cell reception in your area? Try switching to 2g networks unless you really need 3g speed and are in a good area.

Disable auto-sync, background data, Tone down the auto-brightness scaling.
[LG Optimus 4X HD] blavov:
I had battery drain issues with the original v20b (which is why I went back to V10D for a few months), can't say whether they had anything to do with wifi. My phone wasn't rooted back then, and I didn't yet collect battery stats.

Cheers, Pit.
[LG Optimus 4X HD] blavov:
Cell reception dances around -90 at home, higher than at work (-100 to -120), where the drain is much lower. The brightness already very low (unreadable in overcast daylight), plus my stat are from period where I leave the phone untouched with display off. I assume the brightness is irrelevant as long as I don't turn on the display, right?

dimi89 already suggested I should turn off 3G, I had no effect on battery drain.

Today, I thought for a while it finally got better, as I had only 3.5% drop per hour for roughly two hours after I had tried out Network Log as suggested by spamcakes. I had found two or three things (mainly netbios traffic, plus a router feature causing infrequent broadcasts) which kept the phone awake and disabled them. For about an hour, everything worked fine, but then the battery drop went back up to abround 7%/hr. Plus; I went shopping this afternoon carrying my phone with me. During that time, the drop was back up to 9-10%, repeating the drop from last week. So it wasn't Carbon ROM causing the drain, LS seems to have the same problems.

Cheers, Pit.
[LG Optimus 4X HD] dimi89:
Banging my had agains wall for couple a days and honestly dont have any idea why so much drain.Try flashing zaiben rc6 and report please.What apps do you install?

Послато са LG-P880
[LG Optimus 4X HD] blavov:
I won't be able to flash a new rom (and reinstall everything else thereafter) before next weekend, as I need my phone usable during work days.

As to the apps I have installed: I use Facebook, Google+, the app of the German News magazine "SPIEGEL online", Android Weather, CalDAV sync and Simple Calendar Widget. I have used K-9 mail for IMAP access, but have switched to Aqua Mail just to test whether K-9 might be resonsible. There are quite a few more (I count a total of 98 apps in my launcher), but the others shouldn't run in the background (apart from system stuff like Play Store).

So far, I haven't seen a significant change after switching to Aqua Mail; last night, the phone dropped from 100% to 57% in less than seven hours just lying around with display off.

I have installed the app "Netzwerk Log" to protocol what network traffic might keep the CPU awake; so far, I haven't found anything suspicious apart from network access by the Mail client every 1-2 minutes without any new mails, even though the the app (both the K-9 earlier and Aqua now) is configured to use IMAP IDLE / Push Mail.

If I should look out for something specific in my network log, feel free to tell me.

Cheers, Pit.
[LG Optimus 4X HD] frankie_p:
First of all, thanks for the detailed reports on what you have done. In my case the culprits keeping my mobile awake are PowerManagerService (4hrs!!!) and the famous wlan_rx_wake (1 hr & 20 mins!!!) based on what BBS is showing. The device keeps hovering around the 340 MHz (4 hrs & 22 mins) & 475 MHz (2 hrs & 41 mins) frequencies. The mobile was in deep sleep for 6.5 hrs with an avg battery drop of 4.8%/hr. Current battery level is 14 hrs with about 30% left of juice.

My current set up is SlimBean build 8 with OP 2.7. I use Automagic Automation to control the switching between WiFi and 3G (and other functions, I like it better than Tasker), Greenify (everything hibernated), Clean Master for killing tasks and cleaning storage, Trickster for tweaks and SetCPU. I was about to do exactly what you've done so you saved me some time. The thing that baffles me the most is that from the moment I switched many months ago to SlimBean and the OP kernel, the device would go over the 24 hrs mark quite regularly with normal use. It is only recently that the battery has been drained a lot by these wakelocks.

I tried the Jellyfish ROM (good ROM not in XDA) which is based on stock and the battery seems to behave better, but I had nothing installed nor did I use it for days. I love SlimBean and the work of Demetris, and I don't want to think that I may have to change ROM/Kernels in order to have better battery. I personally don't think the issue is related to ROM or Kernel, but rather some rogue app or leftover or even some update to one of the apps installed. If I stop being lazy I may do a test to see if the apps are causing any issue.

Could I ask if you tried to run the phone for a few days with no full restore of apps from the Play store? Just stock with few (if any) apps installed? I wonder if disabling Facebook, G+ and similar apps may help with the issue.
[LG Optimus 4X HD] dimi89:
[MENTION=5491974]blavov[/MENTION] 98 apps are .. O.O i mean i dont have that many apps in my "all apps" folder on market.Try using phone without any apps (except what you need for work) installed after flashing rom.You could for example switch facebook app and open it from browser (no notificiation but everything else is same).Some of that 98 apps are waking cpu and dont let him go into deep sleep i am 90% shure in that.When you have time test it like that and report here,and from then we can go and "hunt for red october" app ;)
[LG Optimus 4X HD] blavov:
As I mentioned earlier, I need to be able to use my phone on a daily basis, which at the very least means E-Mail, WhatsApp (which is used by colleagues at work, otherwise I woudn't have it), Calendar sync. Without that, I would need to buy a different phone to use while I'm tinkering with this one, which defeats the purpose.

Secondly, Facebook, G+ & Co. were my first suspects, which is why installed apps like "Netzwerk Log", "BetterBatteryStats", "Android Firewall" etc. in the first place. But none of the logs gave any indication whatsoever that this problem might be in any way related to them. Have you read anything to that effect in my logs?
[LG Optimus 4X HD] blavov:
First of all, it's only 82 - I miscounted my apps because I thought one launcher page was 4 by 6, when it's actually only 4 by 5. I narrowed them down to 65 now, uninstalling a few apps I only used once or twice in the last six montg.s

Me neither - it's only 76 there.

[MENTION=5491974]blavov[/MENTION] whats app isnt,facebook isnt the problem since i am using them.When you just uninstall app you left behing some parts of that app on your system partition and that is why we are asking for clean flash.Ofcourse that phone is ment to be used but untill wr figure out why your phone is acting like he have 800 mAh battery we must start from base.Also i noticed that you use trickster mod and cpu thrill or something togheter witch isn't great idea since they can couse some problems because they are doing basicly same thing.Trickster mod is great app and i like it but for whatever reason it wont work good on my dvice and i dont use it at all...So when you have time do fresh install and just get few must have apps for you and write us what is going on. Hope that in the end all this writing will help you.
[LG Optimus 4X HD] blavov:
Hello again,

three things:

I have tickster MOD installed and had no problems so far with it, plus I don't know anything about an app called CPU thrill, so don't know where that should come from.

I still don't know which apps to not install immediately after reflash. As I have absolutely no clue whatsoever which apps might be causing the problem, the only option from my perspective would be to start without any apps (which means I'd need a second phone).

Actually, I have not installed any apps after my last reflashes - Google Play Store did so automatically, without even asking me which ones to install - it even installed apps I tried out once weeks before and then deleted again. Is there a way to configure your Google account so that only the apps I actually want to install get installed again?

I'll try to reflash the phone as soon as possible.

Cheers, Pit.
[LG Optimus 4X HD] dimi89:
Must be mistaken about no frills cpu i thought you mentioned it. When you flash rom again install only "musti have apps" for me they are : whats app,facebook, greenify,adaway,instagram,wakelockdetector,youtube,tapatalk.All others i install just for fun not really usong them.To fix problem with google playstore installing all that apps just uncheck "backup and restore apps" and you will be fine i dont use it at all since i lije to do install what i need manually.You will find that option in setting under Personal just below "language and keyboard" .
[LG Optimus 4X HD] blavov:
Hi,

without a decent mail app, I don't need a smartphone, so I can't work with your minimal setup. Furthermore, my contact and program settings are backuped to Google, without "backup and restore apps" I don't get them either. I've seen that that Zaiben ROM proposed here doesn't even include that Google restore option, so that is out of the question. .

I have not nearly enough time to redo everything app-by-app by hand (these tests have already eaten up all my free time in the last weeks), so unless there is another option, I can't do what you proposed until I have two weeks of vacation back-to-back (which I haven't had in 22 years).

It looks as if I'm stuck with a battery-sucking phone until I buy something else, then. :(

Frustrated as hell, Pit.
[LG Optimus 4X HD] Conquerora:
I have similar figures and the same problems as in OP. The problem is with wi-fi but I need wi-fi on almost all of the time so turning it off is not a solution. I am on CM 10.1.3 + idoak v08 kernel (but I tried many kernels). The issue was the same with CM 10.1.2 as well. I am very frustrated and that battery life ruins the experience of otherwise a great phone. I am thinking of going back to stock 4.1.2 (which had location battery drain for me, but when location is off it was fine) or even to stock ICS when I get the time, but I will try Slim Bean first. Also, I have set a static IP for my phone on my home network and even at night when there is no other active device on the network than my phone I still get the wakelock.

BTW, is the updated wi-fi drivers by demetris in the Optimus Play thread compatible with CM. 10.1.3 or are they only for Android 4.3? Anyway, I hope we find a solution soon :)
[LG Optimus 4X HD] blavov:
This d*mn phone kept going on my nerves - and just to try out everything, I sacrificed another evening/night last night and reflashed my phone to that Zaiben ROM I kept gettings recommendations for. To keep things simple, I installed just two apps beyond the things that were on it to start with (plus the four or five Google apps that are installed/updated as soon as I enter my Google credentials, even if I don't use automatic backup/restore).

These two apps were BetterBatteryStats and Aqua mail (as that behaved maginally better than K-9 in my last tests), the latter one set to "never update automatically, just use push mail, refresh the connection every two hours (maximum value) and don't send any keepalives ever.

The fruit of my labors: 6% drain per hour, doing absolutely nothing with the phone whatsoever, and having installed only one background app. Combined with the fact that the Zaiben looks ugly as hell and has none of the features I've come to like - starting with a readible battery display in the status bar - I will not waste any more time on that ROM and will throw it off my phone as soon as possible.

So back to square zero. :(

Tired (both physically and mentally), Pit.
[LG Optimus 4X HD] Conquerora:
I am starting to think it might be a faulty batch of devices. I am reading posts of so many people talking about great or at least decent battery life and yet this is not the case with me even with the same rom + kernel combo. I think my problem is not that the phone does not go to deep sleep so much, but when its awake it spends a lot of time in 475 MHz instead of say 51 MHz. That could mean the difference between 7-8%/h to 1%/h. If only I knew what to do about it.
