If your battery is flat out, plugging in the usb and pressing the power button once will show you the battery charging indicator. Pressing the power button again while the charging indicator is showing, should start the phone.
[LG Optimus 2x] Skyfall007:
yes! But what happens ? why it has a completely drain?
[LG Optimus 2x] stevvie:
On the first Spica says

+Reboot in to recovery

+Do a Nandroid BackUP

+Install HP Performance Pack

+Install HP RC10/9 or any of HP kernels only

+Reboot

So you should install the PP and THEN the kernel.
[LG Optimus 2x] Ferrum Master:
Something is really messed up with this latest release. The phone doesn't sleep.

I've measured the current as many of did and indeed... it manages to get 3-5mA(Which is a lot) after a while then it starts to do something again wakes up and boosts up to 200-300mA... :eek: and thats it...
[LG Optimus 2x] Striatum_bdr:
Try to just plug your phone with wall adapter without turning it on. If there is a problem here (I mean if phone doesn't charge), that can't be kernel related, so hardware issue.
[LG Optimus 2x] Skyfall007:
man u didn't understand me. I can charge the phone but when it is off it has completely battery drain. That's my problem, not charging.
[LG Optimus 2x] Ferrum Master:
Yes it can be btw... X10(just remembering it, we had this certain issue) and others needed to file chargemon from bin folder to do offline charging as it should...

If the phone is dead, just nvflash it...
[LG Optimus 2x] Striatum_bdr:
There seems to be a problem with battery drain: phone idle and 450mA drain....

With system tuner what I can see is that CPU is very often acitve, from 4% to 60% most of the time, not rarely 100%.

In active processes I have 18 logcat daemons (!) without system modification from me. They are almost inactive but...

I'm in a poor GSM zone, with probably frequent signal search, but it's a place I use to be, and I've never seen this behavior with battery...

Will probably downgrade the kernel lol
[LG Optimus 2x] coldfear00:
when i changed vm swapiness to 80 after a reboot swap disappeared any idea why this happens and how can i get swap back with swapiness with 80.
[LG Optimus 2x] Ferrum Master:
Permissions are correct?
[LG Optimus 2x] coldfear00:
sry im a little noob. im using thanatos 5.1 it has HP RC11r built in with 372mb swap. i heard sumwhere that changing vm swapiness to higher number gives swap more priority than ram and when i changed it to 80 bam no more swap for me :(

can sum1 plz guide me how to get swap back with 80 swapiness.

P.S i dont need perfomance im a hardcore multi tasker i jus dont want my apps to restart when my ram is full.
[LG Optimus 2x] Ximo F. Verde:
no problems w swap here, and after an initial apparent high drain, i rebooted, calibrated and bat life looks great. I do however notice some strong stutter/lag that i never had w previous releases, noticeable on opera while scrolling when page is still loading (used to be super smooth always), on xda when scrolling fast and a couple of more cases. Its really frustrating cause the last rc11 beta didnt have this, neither did the earlier versions (sr2, rc8r). 1st time im havin this on a hp release. Something to do w the 2nd core scaling maybe?

ps. gr5, no pp/oc/uv
[LG Optimus 2x] coldfear00:
even i didnt have any problems with swap before changing the value of vm swapiness to 80 in systweaks in int.d folder. its jus that swap wasnt being used much so changed it to 80 and now have no swap at all. :(
[LG Optimus 2x] Striatum_bdr:
Reverted to r11 one hour ago, and since then battery drain decreases slowly to 45 now, probably lower later this evening.

So it seems really coming from latest version, considering that I changed my ROM last night it can be also an incompatibility with 20I?
[LG Optimus 2x] spica1234:
Nope system resources
[LG Optimus 2x] yukkio:
Ok, I'll try.

Thanks M8.

[LG Optimus 2x] Bir92:
ok thank you im just flashing 32 v and i hope to feel any different compared with topoblaze in 1.9

thank you for your work!
[LG Optimus 2x] spica1234:
Original is 16BPP.
[LG Optimus 2x] spica1234:
Welcome
[LG Optimus 2x] invinciblervd:
What is BPP ? And what's the difference between 24BPP and 32 BPP ? And which is advisable ?

thanks in advance.

[LG Optimus 2x] yukkio:
Well usb debug mode problems gone :D Tomorrow I'll wipe battery stats :) Impressive

Thanks again.

BR.
[LG Optimus 2x] Bir92:
thank you the kernel is very good

benchmark @1.2 Ghz with topoblaze 3700 and with your new kernel 3950 !

so next step wait till battery is down 0% (should the phone shut down automaticly) and than just use Battery Calibration and unplug the phnoe and enjoy battery life right?

thank you
[LG Optimus 2x] Deathmo:
You mean load until 100% and use calibration.

Then dry until 0% and load it again and good it is. :)

Recommendation:

-Battery calibration. After calibration let it disachrge full for the first time then full charge. Then you're ready to go! Full discharge needs to be done ONLY ONCE after calibration.

Procedure:

-charge phone full when its off, start phone. Charge till it shows full status. Charge more for 15mins untill you see battery voltage at 4182mv. Then calibrate battery with Battery Calibration App.
[LG Optimus 2x] Bir92:
yes thank you

edit: Benchmark @1.2ghz 4050 GREAT!

thank you spica for your hard work and this new kernel!
[LG Optimus 2x] gideonrs:
CMIIW.. isn't our LCD only support 24bit colors?

is force to 32bit will bring any differences?

sorry for noob question :D .. anyway, I use this kernel from beta version, now ready to flash to RC1! .. :D Thanks Spica!
[LG Optimus 2x] spica1234:
OS system supports 24BPP ,LCD pannel 18BPP and frame buffer tegra driver upto 32BPP

E.g. if your music player support 98khz output and soundcard 44.1khz.

Downsampling from 98khz to 44.1 . slight noticable in videos and images:)
[LG Optimus 2x] gideonrs:
ic ic.. so is there will be any effect w/ 32bpp kernel, spica?

anyway, i've flashed 24bpp RC1.. :D .. thanks!
[LG Optimus 2x] Ximo F. Verde:
Hello Spica

Thanx for all yout hard work and dedication :) Just a couple of quick n easy questions i have right b4 flashing ur kernel:

1) If i got it right, one can flash this kernel on a stock ROM as well as customs right? After flashing, would it b possible to revert to stock kernel later, and if yes, is the stock kernel (flashable) available anywhere in this thread or others (if you know)

2) Im not interested in overclocking, nor changing any other setting as far as CPU is concerned (lookin for stock speed/voltage/governor). Are these settings as-in-stock in your default configuration?

Thanx again for ur time

Peace
[LG Optimus 2x] spica1234:
Which rom youre using. If topogigi then you will find stock on main page. If others than a rule of thumb always

Backup through recovery if incase you wanna go in back. You should restore through recovery

It does support OC. If you wanna change then only otherwise default as of stock kernel 1ghz
[LG Optimus 2x] spica1234:
Default is of 16BPP

Slight in videos and images You will notice.

24 is recommended and good to go with:)
[LG Optimus 2x] Striatum_bdr:
Yes I tested both, less free memory with 32bpp (about 30MB less with phone awake but idle), even if no slow down is clearly felt. So 24bpp seems better.
[LG Optimus 2x] Shadowchaz:
Strange my r11-r has a drain of approximately 40ma now its settled down a touch... I'm using it with pp10 if that makes any difference
[LG Optimus 2x] ehmjay:
i had a reboot when i disable wifi :(
[LG Optimus 2x] Shadowchaz:
Mine did exactly the same but it only seems to happen once after that its been rock solid.
[LG Optimus 2x] tablighs:
I had my first freeze on rc11-r , and then again while watching flash video. Hmmm...

Anyway, what app are you all using to monitor battery consumption? I never bother to check because a single charge usually suffice when I am away from charger.
[LG Optimus 2x] krumcake:
I was just about to ask the same question :-)
[LG Optimus 2x] Ferrum Master:
App? :D Use the force... that is called a bench power supply... (at least that's what I am using in daily work... of course there are other methods)
[LG Optimus 2x] wapz:
Whole day on rc11, rock solid, stable, no wi-fi issues at all. Let's see if it survives the night not being on charger but completely idle without Wi-Fi issues this time. Battery-life seems pretty decent.
[LG Optimus 2x] -rumburak-:
Battery life ok here. Nothing extraordinary but just ok: 17h average use 3g and wifi. No hangs. All this on first full charge.
[LG Optimus 2x] Ximo F. Verde:
back on the last test built, lags/stutters mentioned earlier are now gone. best for me so far
[LG Optimus 2x] ehmjay:
which one is the latest test build? im having reboot problems after disabling wifi with rc11-r
[LG Optimus 2x] kfallz:
For whatever reason i'm having crashes using guestes latest rom with rc11-r, similar to previous smsing/similar that rc10 had.... had none of this on my last rom with rc11-r :/ Hazard any guesses spica if some of his changes might be affecting it?
[LG Optimus 2x] Hell_97:
Some users of Thanatos (not me) have experienced random reboot activating Wifi, is related to Wifi module? Please fix it in next version.
[LG Optimus 2x] abwyatt:
Battery Monitor Widget (Pro). Get it on the market. You access it through a widget as the name suggests. And you get nice informative graphical displays like the one attached :cool: Take before and after snapshots to compare your ROMs/Kernels :D And look at the slopes of the graphs to tell you if battery management is working well. Sudden drop offs after intensive activity like web browsing on 3G are good (the yellow strips along the bottom tell you when screen is on), but if the graph stays flat or has a shallow slope with high mA drain, especially after screen turns off, that tells you that the battery power is not being managed well. It can also show you if something is draining power when screen is off by looking for spikes in the graph when screen is off. These graphs can tell you a lot and help you setup/choose the right combination of ROM and Kernel if you know how to read them.

Have been on my latest combo of Hell's Hypnos V2 SP1, and Spica's RC11-R and PP10 for 12 hours now (since release of PP10 :D ) and everything is working perfectly - fast and stable, OC (1200), UV (50 mA). Cannot fault it in anyway. But I am using the Andrev OC daemon to get better wake response from the CPU (Hell's Thanatos ROM uses this natively). Pimp My CPU is inconsistent and sometimes slow to respond when waking.
[LG Optimus 2x] Sckank:
Have used RC11-R and seems stable for me to. -9mA battery drain and seems very stable. Am happy with SR1 though, so reverting back for now at the very least. :) Oh, and Spica ...... you're pretty fantastic. ;)
[LG Optimus 2x] wapz:
Rc11 doesn't have these issues, works smooth and stable on Hypnos v1.0. Rc11-R caused me wifi issues and instability. Now up and running for 24 hours on rc11, silky smooth still.
[LG Optimus 2x] pgmunzi:
Using System Tuner Pro i can see that 2° CPU goes "offline", but the battery usage still remain around 20mA-40mA never goes to 2mA. No Reboot o freeze using OC 1.1Ghz and UV -75mV.

I'm using RC11-R with PP9
[LG Optimus 2x] PhunKEE:
Using stock ROM v20m.

Reboot go cwm.

1. Dalvik wipe

2. Cache clear

3. Install pp9

4. Install 11-r

Reboot

On 1st night, I full charge and woke up next morning having a flat out battery. So Will monitor Will it happen again today.

Is there anything else I need to do to have the comcache working and init d thingy. I have been reading and kinda got confused is it already built in or need to do separately. Not really a programmer pro, but with instruction I can work things.

Thanks

My main reason is to optimize this world first dual core phone to be optional with a better battery life and speed. Not moving ROM yet because still need the lg suite for sync of contact and calendar.

Any suggestion.
[LG Optimus 2x] Striatum_bdr:
Hi,

I gave another try with RC11-R, and it seems good, but at the same time I installed TWlauncher and I'm currently using it instead of Go Launcher.

And I'm experiencing a -2mA good stuff!

Could people having battery drain precise their launcher? And others also to see if there could be a link?
[LG Optimus 2x] Dzhedaj:
Modaco GR5 + RC11R + PPv9, stock Gingerbread launcher, only ClockQ and 3G Watchdog non-stock background apps. Data and 3G are always on.

Battery drain is ~10-20mA, which means ~1% per hour.
[LG Optimus 2x] Ferrum Master:
Oh you people are relying on a fishy app, that itself is a power leech and prevents the phone from proper sleeping accesing BME? nah nah naaah....

Did a clean install. Reflashed baseband v20m Baseband 0725 and Thanatos2X v5.1 EXT4. Like in Freud's psychology this ROM is a pure human rage... and I like it... still miss the large contact pics mod thou...

But leaving that aside, now the phone sleeps correctly, reading from my supply with dummy battery. 3-5mA consumption with peaks(sync services) at 50-100mA max for few secs). For example an Nokia N8 consumes 1-3 mA while sleeping with 20-30mA peaks for sync after several minutes... so there is somethin ill still.

Of course we must keep in mind that also deep sleep mode should exist... Am I right?
[LG Optimus 2x] Striatum_bdr:
Yes the main problem of battery is the deep real sleep, that wasn't possible for a while but I don't remember where we are with this problem.

That's why people were furiously engaged in an underclocking during idle process...
[LG Optimus 2x] Skyfall007:
Hi! I'm on Thanatos2X v5.1 EXT4 with rc11-r and pp10 and my battery consume 1%/per minute.Why?? I like this combinations because is very fast but the battery is killing me:|.
[LG Optimus 2x] Ferrum Master:
Tell me exactly what are you doing and the installation process step by step? What BB you have. Did wipe everything? Remove android folder crap from internal storage etc?
[LG Optimus 2x] Skyfall007:
I have reflashed kdz firmware, wipe data/factory reset, wipe cache, wipe dalvik cache, install rom, install pp10 and reboot. :D

Battery stats is very bad. What can I do?
[LG Optimus 2x] isd88:
-508 mA ?!?!?!? i hope you are talking about a max brightness lcd situation! please check woth a task manager if there is any process running with an high cpu consumpion

edit: take a look to the antivirus ( i can see the icon on status bar ) , i hope it is running a deep scan of your system :D
[LG Optimus 2x] Ferrum Master:
where is the kernel? And why after kdz flash you wipe anything? busybox is installed also???
[LG Optimus 2x] Skyfall007:
busybox is installed by ROM and the kernel too. :D

@isd88 antivirus is not scanning and the lcd brightness is at 40% :D ps: no process with high cpu consumption

ps::: now battery is at -2mA but it is still discharging

What kind of KDZ you have there? What the heck? Mediascanner I suppose is still running or sync.

Come on. Use a plain GR5 or Thanatos etc, install zip via recovery as normal people do. Install 20m baseband all 4 files starting from the largest via smartflash etc...

@spica

I just checked init.d folder, there is systweaks and systweaks~. Even though both is almost identical, but one of them has swappiness 50 and the other is swappiness 90. Will this caused some sort of conflict? Which is actually better? 50 or 90?

Please answer;)
[LG Optimus 2x] Stefan Gündhör:
No troubles here (though I deleted the "~" files in the ZIP and deleted a line in systweaks and changed init.d chmod, but that shouldn't make much difference!)

Not big trouble and I love rollercoaster :p
[LG Optimus 2x] Stefan Gündhör:
Using Test-Build: Battery drain at -2mA (in idle) since flashing kernel, still 100% Battery. That's very good so far, hopefully it won't increase again after battery isn't at 100% anymore (was the case in RC11-R).

---------- Post added at 08:03 PM ---------- Previous post was at 07:53 PM ----------

Ahhh here we go... dropped to 99% and suddenly I have a drain of -28mA ... but I will have to test more hours for useable results :) I will report tomorrow after phone slept some hours.
[LG Optimus 2x] spica1234:
If you want to install PP9. Simply install it over already installed PP10:) It'll replace:)
[LG Optimus 2x] spica1234:
Ok let me know results otherwise I've other possibilities too that ill apply to build another test build:)
[LG Optimus 2x] Stefan Gündhör:
Sure I will send u my log tomorrow.

But the question is, why is the idle battery drain at 100% at

great

-2mA and since 99% -28 (now 27) mA? What is the difference in kernel between consumption at 100% and consumption at not 100%?

However this is still

way

better than in RC11-R (there I had about -47mA in idle).

And maybe it still goes down further after longer sleep, I will send u the results tomorrow!
[LG Optimus 2x] spica1234:
There is two gauge in battery driver, one batt_gauge and one true_gauge.

One what system reports and one what actual gauge is. And thus indirectly its related with % of battery shown.

Wrong fuel gauge reading can report incorrect mV consumed and thus mA.

Either is the way to modify battery driver to fool it with reading.

Okay you check in the morning whether its being stabilized or not:)
[LG Optimus 2x] Shadowchaz:
Installed the test release and it wiped all my app data and wiped launcher and also no longer have a lock screen and deletd google account. And home button no longer works... :-)
[LG Optimus 2x] Striatum_bdr:
Nearly same as me.

Reverted to r11 as battery drain climbed to1400mA...while idle.
[LG Optimus 2x] Stefan Gündhör:
Are you using v20o ROM? Could it be that the new sqlite libs cause this on v20o ROMs? The same libs are integrated in gueste2x v2.2 final (basically v20m) ... and there this problem never occured yet!

But if the libs cause this on v20o, this would be

really

strange, because originally they are taken from the stock v20o!!
[LG Optimus 2x] Striatum_bdr:
JuJu

I use v20o and i can't see how the kernel could have done that. Considering all db present on system ... There must been a reset of all db.

I couldn't even select Swype keyboard (even that was reset) I had force close with Swype installer until I changed kernel (and sqlite with it).
[LG Optimus 2x] Ferrum Master:
Welcome to the club mates... fail is strong with us today, eh? :D

Also lost all accounts, settings etc... factory settings except for apk erase.

KERNEL SHOULD NOT DO THIS! SATAN FORBID DAMMIT!

[LG Optimus 2x] Skyfall007:
hei which is the best combination(kernel+pp) actually?
[LG Optimus 2x] Shadowchaz:
I dont mind it happened, it was a test release so I hope my feedback helps! :-)

If i could just relaunch the setup wizard, I think it would fix the lock screen and home button issues...
[LG Optimus 2x] Skyfall007:

---------- Post added at 11:55 PM ---------- Previous post was at 11:45 PM ----------

guys do u know which are keyboard files in a rom? I wanna replace the keyboard but i don't know which files. Pleasee tell me if u know!
[LG Optimus 2x] Stefan Gündhör:
Currently the new sqlite libs of the Test-Kernel only seem to work flawlessly (without clearing google account etc.) on Gueste2x ROM, Django Manouche 0.4 FPS-Kernel-Version ROM and all other ROMs not having installed one of the latest PerformancePacks of spica. (9/10 -- for 8 I don't know)

The new sqlite libraries have been originally taken from v20o. They have not been changed, they are stock v20o.

Gueste2x is mainly v20M, Django 0.4 FPS is v20o. -- no data wipe for both

On Thanatos p.ex. there will be a wipe of data, Thanatos is v20o.

Gueste2x does not include any of spica's PerformancePacks (though it includes my own ramdisk modifications), Django Manouche FPS version does not include any of spica's PerformancePacks, while Thanatos includes a PP of spica.

Flix1234 uses Stock v20o with spicas PP9 or 10 and also has had the data-wiping-issue after flashing the new sqlite libraries.

If you use unchanged Stock v20o with stock kernel, you also use the new sqlite libs

by default

(and without any problems), as they are integrated in stock v20o.

So, concluding from this in my opinion there is something in the performance-packs not compatible with the stock v20o sqlite libs.

This is a pity, because the stock v20o sqlite libs are way more performant and allow smoother scrolling and higher Antutu results than the old stock sqlite libs from v20l and before (or the one spica used to package with his RC-kernels lately).
[LG Optimus 2x] Skyfall007:
@gueste do u know which are the keyboard files in a ROM?
[LG Optimus 2x] Striatum_bdr:
Yes you are certainly right. I have power packs since long, that must explain the bug.

[LG Optimus 2x] PhunKEE:
Ok. Night 2,the drain is much better. Left the phone at 80% and woke up this morning at 78%. Left the wifi on thru the night. The day use are hard to gauge as I receive calls, check emails, internets. Maybe after a few days I can have an overview of it.

That's all for now.

Ps. Nothing else change from the Rom other than rooting it to do the installation. No modification else than this pp9+11-r and stock Rom
[LG Optimus 2x] carburano:
it seems like only file missing (in test kernel) from gueste pack is in xbin folder (sqlite3)... this is present in pp10 so... maybe wipes depends from it... Just tried to install pp10-->testbuild-->gueste sqlite pack... and no wipe :)
[LG Optimus 2x] Stefan Gündhör:
hummmm ... this is strange because Flix p.ex. was on stockv20o with ppv9 or 10, installed my sqlite pack and had a wipe! What is the difference here between the ROMs where the files work and the others where they don't?

Edit: Ok if u install a PP or newer spica Kernel AFTER these libs it really might cause problems, as spica partly delivers older sqlite libs with his kernels / PPs and then they will be mixed with newer -> crash
