How I've achieved a AVG of -30mA Discharge on screen off. I've actually never had it go this low before.. So I'm sharing my results.

AmonRA's latest

Ext 3, 0 Swap Size, 2 Gig SD Partition

Synergy-Kingdom RLS1 Sense 3.0

Freedom Universal 8.5

Scripts, Supercharger V6 update 8 and 3Gturbochager

Setcpu Screen off 245 min with Smartass

WiFi On instead of 3G

Battery monitor widget... for monitoring

Here's the Kicker, Stock battery... Whatever chip is in it... It allows a low discharge. I've tried just about every other battery and have never seen it go this low on discharge. None stock battery AVG 50-100mA discharge, go figure...
[EVO 4G General] Braneless:
My hw003 phone idles at -21mA, according to BMW. It's gone as low as -16mA.

Evo Deck 1.3d, tiamat 3.3.7, -50mV undervolt. 128/768mhz, interactive gov.
[EVO 4G General] shawayne21:
Is there a guide on how to undervolt?

If so could you provide me with a link please, thanks.
[EVO 4G General] churro7:
True tests should be on 3g
[EVO 4G General] Braneless:
Why?

I use 3g very rarely, maybe 5min per day. Network is garbage in my area and it's a battery killer, so I leave it off and use wifi exclusively at home.
[EVO 4G General] Braneless:
Search for viperboy's undervolt thread in the development forum.
[EVO 4G General] tropicalbrit:
I think he means because more people are in 3G for most of the day, assuming real-world variables of commuting and no access to Wi-Fi. Because Wi-Fi puts less of a strain on the battery if I remember correctly
[EVO 4G General] godgib:
So is that with 3G on or Off, I haven't really done any testing with everything off, I could see how that would give you a little less, but for me I need somekind of data always on.

I guess you can say that stock battery discharges at lower votages, and if you need data WiFi burns less battery then 3G, which I've alway herd, but after some testing, with results i can say that for sure.
[EVO 4G General] Braneless:
Off, as I posted above.

It's a known fact that wifi pulls much less power than the 3g radio.

I don't use autosync or push email because I'm anal about battery life. I'll turn on 3g to check my mail when I'm away from home, then turn it off when I'm done. I used to run Juice Defender for this, but I no longer need it.
[EVO 4G General] MCL1981:
I routinely get even less than that, even with 3G. The battery is not going to limit minimum rate of discharge. Any battery can do that. I have a 3500.
[EVO 4G General] eggsack:
When my screen is off, I get 21-22mA discharge after about 2 minutes. It spikes when system accesses email or whatever every couple hours.

If you want it to stay that low, uncheck Always On in Mobile Network and change WiFi advanced setting to Never Off While Plugged.

I run Seidio 3500.

Someone posted a while back about modifying the plastic that covers the flash on the DVP as it produces lines when the flash fires. I did a simple test with the cover off and the flash worked better with no inteference lines on the picture. Anyone have any ideas on this? I've been having a look and not sure what would be a suitable replacement if the plastic was removed.

My phone keeps rebooting. I thought there was an issue w/ the OS so I wiped and reinstalled the OS but I'm still having the reboot issue. Not sure what is triggering the reboot. It seems that the phone will stay up for about 2 hours before rebooting.

I ran logcat in adb and pasted the results before the session got disconnected (from another reboot) in pastebin: pastebin.com/Akrv0nxW

Any help would be appreciated. Please let me know if you need more debugging info.

[T-Mobile LG G2x] ttabbal:
First off, big thanks to Faux123. This is based on his repo with a few tweaks of my own. I'll be adding more as we go on. And of course, he's welcome to pull any patches he likes from my github.

Changes:

Added zram compressed swap support. I'll attach a script to turn it on and one to see what its status is. It's not like the older ramzswap that requires a special tool, everything is done through sysfs now. Very nice.

Added zcache compressed cache. This is a bigger win IMO, it compresses any compressible data in the cache. This means you can keep much more data in cache, which means you have to read it in from slow flash much less often.

Tweaked the low memory killer to take swap space into account, but only some of it.... This prevents swap thrashing while the system tries to kill processes and free up ram/swap. I also suggest using something like AutoKiller to set the levels to the best performance for your workload. We all run different apps and such, and that can affect how these things work for each user. There is no setup that is going to be perfect for 100% of users. Speaking of AutoKiller, I have found the advanced tweaks to help a fair bit as well. Don't use the memory management one, it overides your settings for things like swappyness. And the IO Scheduler doesn't do anything as we aren't using cfq. Unless you turn on cfq...

On Swap and compression:

While badly configured swap can slow things down, it's far more complex than people think. It also frees up RAM that's not being used frequently for apps that are. So your system can more efficiently use the resources it has. While compression does use some CPU time, our dual core 1Ghz+ CPUs can compress/decompress REALLY fast. Far faster than reading from the flash storage. In theory, this can affect battery life, though I haven't seen any significant issues from it.

Q: But we have 512M, that's a LOT!

A: Well, kind of... Not all of it is accessible to the kernel for running apps. 128M for the GPU, some for the cameras, wifi, etc... In the end, a little less than 400M is available. Then you have to add in system overhead from the kernel itself, Android's OS processes, etc.. That is quite limiting, IMO, so using it more efficiently is important to me.

Q: I don't like compression/swap.

A: Then don't run this kernel. :p

[T-Mobile LG G2x] KingDavid63:
Does this kernel rebuild cache every boot like faux 1.3?

Sent from my MeGaBoT Transformer!
[T-Mobile LG G2x] C-4Nati:
Haptic feedback doesn't work. Faux had the same problem in one of his earlier kernels bbut he fixed it .
[T-Mobile LG G2x] ttabbal:
Yes. I've poked around, but haven't figured out why. It's certainly nothing I'm intentionally doing. I tried using the same initrd from the Weapon stock kernel, no joy. That's about the only thing the kernel should be able to change that would make a difference.
[T-Mobile LG G2x] ttabbal:
I'll test it again, but I know it was working at one point.

EDIT: Argh.. yeah, config got messed up. Compiling now.

OK. 1.1.1 is up, tested on my phone with working vibrate.

Data missing

Hey ttabbal, maybe you can help me a little bit with the issue im having with cyanogenmod based roms,

I've been trying to know a bit more bout RILs and ended up learning that it resides at the kernel. My objetive of learning about it is because no matter I do i cant have data conection on any CM7 based ROM but I DO have data on any Froyo / Gingerbread OTA rom, even tryed to change basebands, change sim card, push the apps related to the telephony from GB OTA to Cyanogen and replace Ril Libs also. Nothing had worked. And this is where you can help me a little: while using your kernel I have the exact same issue! No data whatsoever! No matter what ROM I use, in the other hand using Faux's kernel i got no issue, and bec you based yours in his work im sure you know what exactly changed between them and enlight me or make me understang what can I possibly do to fix my issue.

Thanks!

BTW I live in Guatemala CA, using a data plan from CLARO (America Movil) carrier

Look here at the Wikipedia Link to look at the baseband Im using.
[T-Mobile LG G2x] ttabbal:
I'm happy to share any information I can. Your issue is interesting as I can't think of any changes that should affect the radio. Most of the radio code isn't in the kernel. It's handled by a daemon called rild. We could try reverting some patches. The first thing to try would be to test all the older versions of the kernel. I'll get links posted for you when I get to a computer. If one of those work, we can look at the differences between them to try and narrow it down.
[T-Mobile LG G2x] Whitehawkx:
I'm not so sure the kernel is going to affect your issue much. As ttabbal said it lies in the RILD binary. CM7/Miui has known issues with no data connectivity though it seems to happen pretty random. Have you tried doing a hard reboot? (hold power + vol up approximately 10 seconds) On occasion I have the same issue with no data signal (though cell is just fine). Usually a hard reboot (or two) solves the problem though.
[T-Mobile LG G2x] albertorodast2007:
Yup, its someting else, i even managed to solve the APN dissapearing issue in other way: install market enabler, change SIM code to anything and ther revert back to defualt an it will show u again your APNs just like if you hard rebooted.

I even tried copying rild (/system/bin) from OTA GB rom to a CM7 rom and flash, and nothing, and why using your rom and faux's kernel i got data and if using ttabbal's one i have none? has to do something with the kernel! but thanks for ur posts anyways I know ur busy guys :p
[T-Mobile LG G2x] ttabbal:
Your description sounds like the known cm7 apn bug to me. Installing a kernel usually triggers the bug for me as it involves soft reboots. With dragon, do the data workarounds work? Exactly what ROM are you running?
[T-Mobile LG G2x] albertorodast2007:
I think im not leaving things clear, my above post was what I did to fix apn dissapearing when i flashed cm7... and even if i hard rebooted (or used the market enabler trick) and apns where restored still couldnt get data to work...

Im usign whitehawk's rom now, but if i pair it with your kernel, the issue i have is not that apn dissapear (like they did in cm7, bec of the known issue) but that I cant get data to connect.
[T-Mobile LG G2x] ttabbal:
OK, just making sure. Here are the older versions of the kernel. Try them out and see if any resolve the data issue you are seeing.

1.1: http://goo.gl/e913p

1.0.3: http://goo.gl/7QY0a

1.0.2: http://goo.gl/O6PDb

1.0.1: http://goo.gl/OWkG8

1.0: http://goo.gl/gLeFz

I honestly don't expect them to, but if the only change is the kernel, it seems like it could be related. Could you also attach a file with logs when it's trying to connect? Perhaps also with a log when booting from Faux's kernel when it works right?

adb logcat > log.txt

adb logcat -b radio > radio.txt

I might be able to see something in there...

Just to make sure we're on the same page, by Whitehawkx's rom you mean Weapon 2.4? I just noticed your sig says 2.3... I don't see sigs when I'm on my phone, so I missed that before. :) Have you tried updating to 2.4? It might help... it might not... :)
[T-Mobile LG G2x] albertorodast2007:
hahahaha noob mistake... yeah im on 2.4 just updated my sig, thanks for pointing me that, thanks man! gonna use adb to get u some usefull logcats...

BTW i've seen some interesting updates on the nightly changelog for the p999, gonna try flashing latest nightly and see if something has changed....

[T-Mobile LG G2x] bighulk666:
Been running the kernel for about a day, both scripts running with script manager, no freezes or issues yet. Been trying to cause problems like I've had with other kernels, and i'm not getting them.
[T-Mobile LG G2x] Darkseider:
First and foremost. This kernel rocks! The compression and swap is a really nice addition. Did I mention that this kernel is awesome? Thank you! For anyone that has doubts. Rooted OTA + this kernel = heaven. I haven't been happier with my G2X!
[T-Mobile LG G2x] ttabbal:
Honestly, I haven't taken any time to look into it. I haven't come up with anything I should be able to do in the kernel itself to trigger that sort of thing, but using the exact same ramdisk doesn't fix it either.... odd.
[T-Mobile LG G2x] ttabbal:
Script manager is running is with the wrong shell interpreter for some reason. It needs bash to work properly.
[T-Mobile LG G2x] MasterGGM:
I tried this with Weapon G2X 2.5 .. the scripts did not work, and my phone overheated :(

After overheating, the screen "turned on" with the buttons on and a black screen and I couldn't do anything but pull the battery.

Also, the boot time used to be like 15-20 seconds after installing the kernel it took 1 1/2 to 2 minutes each time.

Guess I am just not lucky, no kernels work me.
[T-Mobile LG G2x] derekedw:
Would love to use this but 5 min reboots are bad for me. I switch batteries alot. Would love to see that cache rebuild fixed.
[T-Mobile LG G2x] allofusjw:
Make sure the zram_stats file is on root of your sdcard (/sdcard). Then, instead of trying to use zram_stats with script manager, use the run-zram_stats I made... http://db.tt/kQonXqF.

Again, original zram_stats must be on sdcard, but do not run it with script manager. Instead, use the script in my link by using script manager.

Please remember to "Thank" if you've been helped
[T-Mobile LG G2x] albertorodast2007:
Saludos ttabbal, I know we all got lifes outa XDA but havent u found something unusual at the logs i posted? sorry for my insistence! :D
[T-Mobile LG G2x] ttabbal:
No problem. I read over them, I see the data connection attempting to go through, but not much about why it doesn't finish. It all looks right, other than there not being an interface assigned to the connection in the failed logs. Though why that would be the case, I don't know. Did the other versions help/hurt the connection? Did you try with a fresh wipe of data/cache/system and install just the rom/kernel? Perhaps try removing the wifi calling app if your rom included it? It shouldn't matter, but it does mess with a lot of settings...
[T-Mobile LG G2x] ttabbal:
So would I, but unfortunately, I don't see any reason it happens with custom kernels. The kernel itself shouldn't be able to trigger that sort of thing, the ramdisk could, but I used a stock one pulled from the kernel Weapon ships with. :confused:
[T-Mobile LG G2x] chompipe:
I'm interested in trying out this kernel after reading the OP. I don't UV or OC at all, just looking for something very stable while keeping performance optimized. Since I'm not interested in OC'ing, would this be a good kernel? Thanks.
[T-Mobile LG G2x] FastJoe78:
I thanked you, but it did not work still saying Bash not found. I may have found out what's wrong...will report back in a few

update...still needs to find bash...wtf!

It would be worth a try. You can always flash another kernel if this one isn't performing the way you prefer. Options are good. :D
[T-Mobile LG G2x] allofusjw:
Maybe try using busybox installer to install version 1.18.2. I think that's what I was using at the time because I was messing around with the v6 supercharger script and they recommend it due to bugs in later versions of busybox. Other than that I'm not sure what to suggest. I'm on the OMFGB rom right now so I can't test it again for the ota rom but I just ran it on this rom and it worked. The settings and results from script manager are in the screenshots.

My data connection does not work after flashing this kernel. This is a fresh wipe and install of Xboarder's Stock Tweaked OTA Gingerbread build v1.2.2, then flashing this kernel before booting. Everything seems fine but data connection.

Is there a fix at all for this?

Tried to "Fix Permissions" and now it will not boot.
[T-Mobile LG G2x] ttabbal:
I can't think of any reason why the data connection wouldn't work. Could you try it on Weapon? I haven't tested on that particular rom..

Fix permissions has always been ok as well..
[T-Mobile LG G2x] empmdk:
Alright I flashed this on Weapon and it works fine other than a long boot time. I am running into an issue with undervolting though. Tried using PMCPU to undervolt a little, saved profile, set as boot. After booting up, the voltages are still the original, nothing is saved.

I tried using Root Explorer to mount as r/w and repeated the PMCPU steps. Rebooted to still have default voltages.

How do I change them?
[T-Mobile LG G2x] ttabbal:
Pimp uses an init.d script, and those don't work. Even the stock cm kernel has them disabled. The only option for at boot uv is setcpu right now. I haven't had time to figure out what the problem is on those.

The long boot is caused by the dalvik cache rebuilding on every boot, which the kernel shouldn't cause, but I am not aware of any custom kernels that don't do that on the ota based roms.
[T-Mobile LG G2x] empmdk:
Ok, I had to get rid of this kernel. I started getting some random freezing issues (not undervolted, left alone). Would happen while playing a game or nothing at all. Once had it sitting on the table doing nothing and I tried to use it and it was as if I turned the phone off, but holding the power button did nothing. Took about an hour of restarting, trying to get it to boot back up and finally worked. Would keep cutting off early on the LG logo and then sit there overheating until I pulled the battery.

Last time it froze, caused the internal memory to be corrupted and I had to reformat everything in recovery. Just sticking with the Weapon rom on its own.

That's the ZRAM, I think.
[T-Mobile LG G2x] dmj2012:
If I have v6 supercharger on my phone with stock kernel do I need to do anything with it before or after flashing this kernel?
[T-Mobile LG G2x] IRASadPanda:
Get off stock LG ROM dude, but anyways, you'll have to run the script again after flashing this kernel.
[T-Mobile LG G2x] dmj2012:
I've tried about about four or five others but never had the time to really delve into 'em for now. Next time I flash something major it'll be after some of the ics stuff gets ironed out and that seems pretty soon.

I have to say I was disappointed to see a lot of the roms come with things like rom manager which is kinda pointless on a g2x and titanium backup and a file system browser which I don't use. I ended up freezing almost as much in the custom roms as i did on stock.

In any case I was just hoping I might get a little better battery life with this kernel and may flash it when I get a chance. Good to know ahead to make time for v6 to be run again.
[T-Mobile LG G2x] dmj2012:
So I've flashed this kernel and I can't seem to get the enable_zram script to work. It says Device or resource busy and when I run the checker it has an error. I saw a fix above but wasn't sure what to do with it. Is that a Terminal Emulator thing?

Also I re-ran the v6 supercharger. Supercharger is working fine but I know on the stock kernel I needed to set a script to run at boot to get it to work. Anyone know if I still need that script to run at boot on this kernel?
