Odp: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Newest kernel isn't good for battery.

After 3hours gaming Football Manager 2013 Handheld phone went off. Previous kernel gave me 5 hours of play.

I'm returning to old :).

Very bad 3g drain that is the real problem now:(
[LG Optimus 2x] Rayman96:
Pengus, by taking your kernel source, we can add OC by wkpark manually, or you made some changes to break it?

The thing is, that Shadowgun: deadzone is working smooth on 1.2 Ghz OC frequency.
[LG Optimus 2x] my_dnl:
Please, your config?

It also seems to me that the battery life has decreased... But could be ROM related.

I'm with PA 2.5b02 and kowalski 010 oldbl but battery drain could be related to the ril: tonyp switched from 28g to 30a.

Did you change rom? Kernel has nothing to do with telephony... Ril/bb do...
[LG Optimus 2x] antec123:
yes, i always wipe cache and dalvick before flashing. and i'm pretty sure i flashed the new bl because i'm on cm10 new bl from your thread

Do you have any idea what offering an overclocking kernel will do to troubleshooting? There are already enough posts that report problems that are in fact user errors. Imagine what would happen by adding crashes and instabilities caused by overclocking into the mix. When Pengus has finished changing and tweaking important parts of the kernel, and the kernel has become as stable as its possible, you may get overclocking variants of kowalski by other developers. Till then you have to be patient and show some understanding to Pengus, his work is hard enough as it is.

if you want to objectively compare battery life during gameplay, you should kill every application running in the background and set the radio to offline mode before playing. Bad signal reception, especially on 3g, can suck your battery dry very fast.

Check your signal reception strength. Did you by any chance upgraded from PA v1 to v2? The newer version contains a different RIL and that could explain the higher drain. I really doubt that the newer kernel has anything to do with you problems.

No..im using 06 rom..also i made the 96readahead file as descriebed in page 56...for boot with 1024 read ahead..and i have su big problems...after a reboot the phone takes a lot of time to get su permissions again?!

Just to add a couple things to this perfect reply by skies, when all the bugs are squashed and all the posts in this thread will be only about how stable the p990 is, i might even introduce a 1.2 oc by myself considering how many od you ask for it. But it will be done "the right way" and without any hurry. If you desperately need a gaming kernel, for now, this ain't it. Move along ;)
[LG Optimus 2x] silverkin:

Config.

I'm on pengus ROM new BL, v10 RIL. I had good signal strength.

I know, battery drain depends on signal strength and many other things, but in almost identically conditions I got 2h uptime on gaming more.

BTW. I still have slow charge bug, maybe my 2 USB cables are bad if no one are reporting this bug too.

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Wifi on or off? Gps? Background apps? Kernel can't really drain battery blindly by itself...
[LG Optimus 2x] FatherJony:
Bad reception can also be caused by your provider's network. The read ahead value doesn't have anything to do with super user privileges, but you can delete the file and reboot to make sure it doesn't cause any problems. Did you by any chance installed a new app the last few days? Could you be a little more specific with your su problems? What takes time to get root permissions?

Btw, you should probably post your issues to the CM10 by pengus thread, they seem rom and not kernel related. Please post your follow up there.
[LG Optimus 2x] antec123:
my advice, don't change the value of read ahead stick to 256

and set zram to 10%. it will boost your performance. I/O scheduler change to BFQ isn't recommend, it so slow compared to ROW

I forget about screenshot, but last day amazing thing happened. I woke up and turned on wifi, checked news etc. Then i took off the wall charger and forget about wifi. I have played some games on pc etc etc. And after 5 HOURS i checked my phone. I was afraid it would cost about 10-20% of battery. I was shocked. Battery indicator: 99%.

1% of battery after 5 hours Wifi on. I have to mention that all wake-upers (fb, skype, gtalk etc.) were turned off but still, sync on and... I will try to do this next weekend and i will send a screenshot ;)

Thanks masters Pengus and TonyP! Without you it would be a dead phone. But now, miracles! :)
[LG Optimus 2x] tomsi91:
Its possible, the first percents lasts very long time, than it is discharging faster.
[LG Optimus 2x] proyatzu:
Its still a very good result considering 5h of wifi on
[LG Optimus 2x] BS86:
For the last time: WiFi consumes less then mobile data, and mobile data is turned off when WiFi is connected.

5 hours and only 1% gone is no miracle.
[LG Optimus 2x] kekks:
Its a miracle as it clearly mentions just 1% drop in 5hrs with syn on so obviously the phone was transmitting data and no one has reported only 1% battery drop in 5hrs.
[LG Optimus 2x] BS86:
That the step from 100 to 99% takes the longest is a fact, for the rest see this, I never disabled sync so far
[LG Optimus 2x] Custom40:
Oh yeah? See how stock LG kernel performs compared to that then. It will probably drain 2% per hour at the very least. And after few hrs, you will probably have your wifi chip and modem fried because of LG stupidity.

Remember, you are on XDA. When someone says phrases such as miracle, don't expect something like jumping off a scyscraper and being saved by a big a** pigeon. He is just amazed and happy with the outcome of this kernel. Nothing more, nothing less mate :)
[LG Optimus 2x] BS86:
Yes, but on Kk it is not, and he and some others clearly thought turning off WiFi saves more energy then leaving it on on kk.

every smartphone with good software saves battery on WiFi, just because LG made crap leeds to the believe that WiFi drains energy
[LG Optimus 2x] Patrick Morgan:
Settings > Wifi > Menu > Advanced > Turn on Wifi Optimization. battery = good, with wifi on.

i still get viber messages without a problem from deep sleep. so wifi still runs with this option available. as long as you have wifi sleep policy set to always on (or never sleep)

BS86 is right though. both the 100 to 99 and the final 1% are some of the longest noticed usually. but this is not always the case. and happens more so during calibration cycles.
[LG Optimus 2x] sev3n1985:
Hi Ivan, could you add in next kernel release a new feature like the possiblity to set the vibration intensity? With the Cyanogenmod we have an high intensity (like a drill :D )
[LG Optimus 2x] imayoda81:
that setting doesn't work without new broadcom stack, wasn't it removed in tonyp's 10.2 ?
[LG Optimus 2x] Patrick Morgan:
ah, i didnt know it didnt make a difference =P

its still an option in Tony's TheRom 10.2. either way, i do have better battery life with wifi on, than off, when at home.

[LG Optimus 2x] pengus77:
Aye now that i have some spare time i'll look into it ;)

Still waiting and waiting, but again don't sweat it... i'm working on the 2.6 kernel so i won't have time to get into debugging the 3.1 boot anyway. When it comes, it comes :)

On a side note, i have a 80% working knock knock to wake (to sleep is trivial so i won't even look into it until i'm done with wake), but i'm trying to keep the irq alive when the phone enters LP0/LP1. For now it works perfectly when the usb cable is in (so the phone is stuck in LP2). Stay tuned for more news ;)

Same problem for me, I've solved unflagging a lots of sync from my google account and google settings. Then try with betterbatterystats to find who's the killer of your battery :D
[LG Optimus 2x] Patrick Morgan:
[MENTION=4637606]daas88[/MENTION]

looks like your signal sucks.

if you had a signal below a good amount, the phone would continue to force more power to keep the signal going.

looks like you lost signal once you picked it up. giving a notation of a bad signal area. since there are no visible background running apps. this is the only option i can see from your pictures. .. to test before going to sleep, try enabling airplane mode (you can still use wifi if you toggle wifi after) and see if the battery still drop over night in the exact same place.

And [MENTION=5423821]sev3n1985[/MENTION] you could tag folk like this to save the those on handhelds alot of scrolling. try this above also if you can, to see if its your local signal being a drain on your battery.
[LG Optimus 2x] daas88:
I've already disabled several items that were syncing from the google account, I guess it's not that.

The signal is ok besides my bed (where the phone spent the night), I only lost signal when I posted the screenshots because I posted from to a room surrounded by several brick walls (bathroom :o). I'll still try your airplane mode advice though.

BTW signal. Is anyone of you experienced signal loss, even if you have good signal from bts? It happens to me very often, even 10 times a day. Ie. at home I have ~4bar signal, then suddenly they goes to null. I have tonyp exp-opt with default m1, virtual operator, and v30a bb.
[LG Optimus 2x] proyatzu:
I also think is signal problem, because as you can see in your first screenshot, the signal bar is almost all yellow, this means you didn't have a good signal. That's it. I'm 90% sure that's the problem. You could try placing your phone in a complete different zone, like another room, or at least an other edge of your bedroom, before going to sleep, stay 2 minutes in the zone you left the phone, with the screen on, and check the signal icon, be sure is full, or at least it doesn't get empty in these 2 minutes. If you don't already do it, I highly recommend you to stay with 2g, all the day, except when you use mobile data, only in that case I suggest you to stay with 3g, of course if you're with wifi, same discours, put 2g. It will save you a lot of battery and also, you'll have a better signal as 2g it's more "popular" then 3g. Sorry for the long post but hey :D

i think... no more love for kernel = goodbye o2x.

tonyp and pengus has kept it more than alive. 700+ pages of kernel love really made big difference. if the kernel development goes to a minimum now because of nvidia and lg crap, well then no reason to keep o2x anymore. at least not for me.

i believe in pengus and his magic, but its all way back to july that 126 came out. almost no change since then. cant see what is yet to come that is worth the wait? 3.1? doesnt seem realistic. honestly on this old device with nvidia and lg sh*t..

i read only bad news on development here, no good news, soon its time to look for another device.

i say thanks for everything, i hope good news will make me stay, i really do, but i just dont see anything coming, at least not like they used to back in july and earlier. too many roadblocks because nvidia and lg like pengus say. just sad, end of an era, development stopped since july and it doesnt seem like it will come back alive like it used to. bad news everywhere, why still have hope i dont understand? this is nvidia and lg. the worse combination ever.
[LG Optimus 2x] flopower1996:
i agree with you. But sit back and wait what penugs has to offer... I feel some realy nice things are currently in development. :fingers-crossed:
[LG Optimus 2x] KoRRo89:
I also believe in pengus, I love it's work, but I also agree with the previous post, without constant love this phone is dead, I need a faster and more reliable phone because I have no more time to spend on custom roms and kernels... The p990 will remain my secondary phone (for my secondary Sim card) and a "play phone" to test all the weirdest things I can find on the web in my little spare time.
[LG Optimus 2x] gramaglia:
Don't think so. If developing would've been so easy, new kernel should just be 3.10 and should be here right now. New options for our phone? What we really need? Now we have a reliable device, but don't think that you can transform it in a S4 only by changing kernel...

Wanna change device? Well, go ahead, it's a free world.

Anyway.

A reliable device is just much more than LG and Nvidia gave us. And it still is, compared to other actual products, even top products.

Love for kernel is here. Hard work too, so shut up and wait.

I just put it plain, no offence meant to anyone.

I have a P990. And I'm proud of it.

Now, back to kernel.:D

and s4? hell no, nobody expected anything like that at all, anyone with high expectations need to calm their expectations. its just sad to see so many people (including myself or i was) are waiting and donating, thinking the development can continue like it did almost a year ago. the phone might be alive, but realize that development is dying.

time to stop dreaming, its good to have hope, but truth is, development has been dead since july and probably will R.I.P.

have fun if you wanna keep dreaming
[LG Optimus 2x] pengus77:
Guys, development slowed down since July because i didn't have a phone to work with. Now i do, and i won't let you down after you helped so much with the problem. The current issue is that lg modded a load of stuff in the kernel, driving it away from the standards and adding crap in places where it shouldn't have been. Specifically they changed how the irqs wake up the phone and hardcoded the gpios that can or cannot wake it from lp0/lp1. These changes are freaking hard to track down, and I'm trying to actually clean up their code and roll back to standard linux behavior. Stay tuned, I'm not leaving anytime soon ;)

About knock knock..

Pengus, you might want to take a look at this GitHub. They call knock knock for sweep2wake in their forum. It is especially synaptics_3200.c.rej that could be interesting to look into.

Best of luck.

And about the development here in general. Keep in mind we still have an extremely well functioning (and fast btw) phone. This itself should be enough reason to have more than enough patience. For your own safety, just quit the whole "I want to see everything that is out there on this phone"- attitude. The one and only thing I am waiting for is an alternative to wake the phone as my biceps are getting worn out of me wrestling with the power button ;)

Trust me when I tell you, the power button is the only thing I feel is 2 years old. Everything else works and feels as if it is a brand new phone. So, start writing your thank you notes to the penguins who are, from their own good will, continuously putting an effort at improving what has already been improved.

And finally, remember..
[LG Optimus 2x] KoRRo89:
I totally agree with you, Just to be clear, mine was absolutely not a complaint about pengus work, I'm totally aware that without it's work this phone would be already dead, instead we have a fast and reliable phone. My problem is I have no more time to spend, and this phone needs a lot of love, not from pengus but from myself, to remain fast and I simply can't do it. Without a wipe every month or 2 it gets slow and it needs constant attention on the ram side to avoid slow downs during the day. Also my battery is slowly dying and lasts less every day. This is never been a problem to me since a couple of months, now I feel I need something better on the hardware side, but this shouldn't be interpreted as a complaint or a pengus fault, I still can't believe how great this phone is thank to pengus work, and I will never thank him enough for what he has done.

I hope now it's clear what I was trying to say.
[LG Optimus 2x] Fíghter02:
My hope is that we one day might have a 3.1 kernel with trim support, which definitely would help our phone stay fast for longer.

What do you mean when you say the ram needs constant attention? I trink ram management works very well with TheROM exp-opt + kk126.

I understand that hardware improved a lot the last three years. However, last time I went to an electronics store I compared my p990 to a Samsung galaxy s4 and the p990 didn't actually feel 3 years older. Sure, the S4 has much better hardware, but the general feeling of responsiveness isn't a lot better. I think that is very impressive for our p990 and it really shows how much the developers of this section has improved our device! :)

Not trying to change your mind here, just curious to hear more :)
[LG Optimus 2x] Jackson-five:
I agree to this. Especially the display totally rocks compared to the samsung-screens... A friend bought a cheap sony xperia in the last weeks and it looks and reacts like a stone... I think our P990 works, feels and looks much better than the actual phones in a range between 100-200€.

:good:Thank you Pengus for your great work - with your Kernel and a new battery my speed is just great!!! Take the time you need for developing - you've already done so much for us!:good:
