Can you write a FAQ for this? So topogigi could include it in the first post.
[LG Optimus 2x] Mediax:
Just install V6 SuperCharger and now no more launcher redraw (Option 12)
[LG Optimus 2x] deep750:
I have measured my battery consumption, as I think it is using to much battery. I disconnected the phone from charger at 100% (4169 mV). I went from office, took the bus, and used it for 45min, surfing web using 3g with Opera mini. I walked for 8 min, meaning it had been disconnected from charger 53 min. The battery is down to 80% 3933 mV, 36,5C.

Is this consumption normal?
[LG Optimus 2x] jay_snake:
You got a link to that?
[LG Optimus 2x] FBlablabla:
That's exactly what I did... still all files in root disappear with those 2 boxes checked, even in your 1.8 version... They ONLY appear if root explorer IS UNCHECKED (weird !)

BTW, while applying 1.8; I found an odd thing as pimp my cpu could let me choose the governor ?? Alas, it didn't stick after reboot...
[LG Optimus 2x] smoki3:
The battery consumption is realy very high in this rom. I go back to modac GR3.
[LG Optimus 2x] jay_snake:
Sure, here is the FAQ:

Working GPS with topogigi v1.8

I managed to find a workaround for the GPS problems on topogigi 1.8. I came to the conclusion that the GPS wasn’t getting a fix at all, or just for 1 second and then it never came back. So I looked for a solution and I think I found one.

1. Get the services.jar from Paul Gr3 release.

2. Use Root Explorer (or something like that) to push services.jar to /system/framework

3. Set permissions to rw-r—r—and set owner to root/root

4. Go to the hidden menu -> GPS TEST -> System settings -> SULP Setting -> SLP Server Setting and make a new one and save it. Name: Nokia, slp: supl.nokia.com, port: 7275, cert. file: NULL, TLS Setting YES!

5. Select the new SUPL Nokia and hit back and go back to SULP Setting: Enable SLP Auto Provision

6. Hit back and check if MOLR Protocol is User Plane and if C-Plane Setting is Loc Estimate

7. Hit back till you are at your homescreen, enable GPS and reboot our phone.

8. Use GPS Status of GPS Test to see if you get a fix. I always get an fix now when (re)booting my O2X with GPS on(see note)

Note:

Reboot a dozen times with GPS OFF: No Fix, at all or loosing it directly and not coming back

Reboot a dozen times with GPS ON: Fix, and keeps it

So GPS should be ON when rebooting your O2x, or else no fix! I think it’s best to keep it always ON, it shouldn’t make a noticeable difference in battery life.

Make BBA compatible with topogigi’s 1.8

1. Make sure you use services.jar from Paul GR3 release (see step 1 - 3 from above)

2. Use root explorer to change a few lines in the build.prop. There are 2 lines ending with: =p990_EUR-xx, change that to =p990, save it and you’re done.

3. Reboot your O2x and download the newest Button Backlight Alert; https://market.android.com/details?...id.buttonbacklightalert&feature=search_result

4. Start BBA and set it up anyway you like.

- Why BBA and not LG 2X/Black/3D Notifications?

Both have the same options, but BBA is MUCH more batter life friendly because it doesn't use a service to monitor the state. It’s build in in the rom.

Colour me happy

No problem when moving from Wifi to 3G etc.

GPS took a very long time to get its very first lock - now I get a lock in my living room in 7 seconds - that's impressive!

Only big changes I make are reverting to stock Android calendar, using GO Launcher and freezing a load of LG crapware.
[LG Optimus 2x] squide:
Without the Patched Service.jar, the GPS ON reboot trick will still work !

no need the nokia server, use google will also work.

out of the box, LG's stock froyo is the same !

GPS ON, reboot, it will work correctly.

Did you use the save as boot?

if so,

check the scripts inside /etc/init.d

check one by one.. and try to understand them

"S_volt_scheduler" is actually created by PimpMyCPU

and this is the script to tell the kernel the range for scaling.

+1 And it seems that the battery drain is not so horrible. After 22h still over 45% (minimal use, a few phone calls, some sms/whats'ups)

About GPS, when I installed 1.7 I could not get any lock. I armed my self with...patience left the phone for ~10-15 min with a clear view to the sky and it locked. From that moment it locks in seconds!

It stands all on the first page dude :D
[LG Optimus 2x] squide:
Q. I still don't understand why I should use an app to lower operating frequencies on sleep time to save battery. There are several tasks running in background in an Android phone, and limiting the CPU clock frequencies during sleep will lower the speed at which background tasks are executed. The lower the speed will be, the longer the task will take to be executed. So, the battery will not be saved, but wasted because idle times between tasks will be shorter.

A. That's not true in this world. It can happen in others, maybe, but here on planet Earth energy always behaves in the same way and obeys to the same laws. Think about your car: you have to use it to have a trip from point A to point B. Do you think you will save more fuel going from A to B at 120mph or at 80mph? True, you will be there faster in the first case and your car will rest a little after the race, but fuel consumption will be higher. E=mc2 (how smart I am! )

Sorry, but the Linux Kernel and your CPU are not running like a car.

and if your car run 80mph with 6000rpm, and 120mph with 1000rpm

what do you think? It is not that simple, my friend :)

and the Power for the CPU is ..

P = CV^2f

--

C - Capacitance

V- Voltage

f- Frequency

P - Power (W)

and energy consume = Power(W) x Time(s)

But one thing can be sure is the more background tasks running, the more unlikely your slow paced sleep max CPU can actually come to sleep.

you can run some adb command from your computer and see..

adb shell "while true; do cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq && sleep 1;done"

My lowest is using 389MHz , and I never see frequency higher than 440MHz with the screen is off. on 1.6 SP1

[LG Optimus 2x] ryaneu:
Topogigi, can you investigate something.

Battery life seems to have gone worse in V1.8
[LG Optimus 2x] sorcio91:
Nothing at all, in all the night (8.30 hours) i lost 2%!!!

And i used the phone very very much for all the day, i still have 15%, but i really used it too much, wifi, gps, call, sms, play, several reboots for tests with OC and so on
[LG Optimus 2x] Topogigi:
Examples are made for this. I cannot imagine you think about me as soemone who cannot discern a car from a phone.... :D

This is exacltly what I told in the FAQ section. Some things cannot happen on planet Earth. Or you are simply talking about two different cars or different drivers. Try to explain me how the same car with the same driver could behave like this, because this would be very interesting for automotive industry.

That's what wikipedia could tell about it. It shows clearly that with the same capacitance, you can lower power consumption using:

a) a lower frequency

b) a lower voltage

or any combination of the 2 listed factors. That's exactly the reason why we

a) underclock

b) undervolt

And since we cannot undervolt under a certain limit for merely physics reasons, the remaining part is underclock. (why did you delete your consideration about voltage vs. frequency? It was correct!)

That's the way it should work in any case. CPU governors and the cpufreq daemon are made precisely for this: lowering cpu speed when no cpu demanding tasks are active. But in our case, things are complicated by some Nvidia quirks. Our scaling driver was made some time ago by Nvidia, and it has been modified and updated only for kernels newer than the one actually available for the Optimus 2X. It cannot use governors other than performance and powersave, and it is unable to tune the cpu frequency for every core indipendently. So, if you have a light task in background, two cores are set at the same frequency and you always have a dual core cpu in action even to perform the least demanding task. Provided that the task can be multi-threaded, you can use both cores at a lower speed to perform a task in the same time. So, forcing a lower speed is not always unuseful, because we have a beast of a CPU that is forced to turn on two cores for tasks that could require relatively low cpu power.

On sleep time and overclock influence on them, I tested them simply after some hours with uptime: they were roughly the same with and without OC daemon. But this is a thing you can try easily by yourself.

It's not so easy, my friend.... :D

Bottom line (and here I am with you): I introduced overclock daemon only because in GB leaks battery life is so poor. If only they had been better....;)
[LG Optimus 2x] lucfig:
V6 supercharger is optimized for the milestone and may change some tweaks topogigi made to make the rom so great. I prefer to keep everything as the developer made (after testing the rom and with much more knowledge than me).

I just added the line in build.prop to make my Launcher harder to kill or change the OOM values a little bit.
[LG Optimus 2x] mba780:
SMS messages "en masse" and no connection via USB

I´m new to the 2x and I have to say: GREAT - especially thanks to this incredible ROM!!

But since I installed the OS i notices two issues I cannot explain myself:

1. When I receive an SMS this message will show up a lot of times, although it was sent only one time. I already changed the simcard - without success. Has anyone of you an idea? BB 725 is installed // using the "onboard" SMS-app (by LG?) in threaded view.

2. the other thing is that I quite often cannot connect to any computer via USB. There is no connection recognized either by the phone nor by my PC. I tried different PCs and devices. The only thing is that the phones turnes into "battery loading", which actually happens... Even telling the phone to choose USB-mass storage automatically doesn´t help. From time to time the connection can be established. Could something like a dirty flag be the reason?

Thanks in advance for any advice :-)
[LG Optimus 2x] lucfig:
Before anyone asks.

To change the OOM values, you may use Auto Memory Manager.

I am not using it, but I used to run an script at startup with Tasker and locale Execute plugin. This comnamd:

@! echo "2560,4096,6144,12288,30720,38400" > /sys/module/lowmemorykiller/parameters/minfree

It is pretty aggressive with background apps. The values may are multiplied by 256 in the command.
[LG Optimus 2x] lucfig:
1) Have you got the default sms app and another one installed? (go sms, chomp sms, etc)

2) Don't know. Did you come from 1.6 or flashed 1.8 directly?
[LG Optimus 2x] Kickasskev:

[LG Optimus 2x] Kickasskev:
no mate no themes, going on to third wipe now to try again never seen this before :confused:
[LG Optimus 2x] lucfig:
But it seems to be a similar issue. I solved my problem ONLY by full wipe, flashing 1.6 again, run trough the first start wizard, and then flashed 1.8. I installed a new baseband before 1.6,but I don't think it is necessary.
[LG Optimus 2x] Kickasskev:
No still no good will try 1.7 now.

I even tried converting to ext4 my self then flashing but still no joy
[LG Optimus 2x] salisbury_steak:
If you're coming from a different ROM, you need to full wipe then flash 1.6 first, set up your wifi and google account, then flash 1.8.

Were you able to flash 1.6 first?
[LG Optimus 2x] felipemadox:
Bootloop after install 1.8 coming from modaco gr3.

Even with fullwipe i always got bootloop.
[LG Optimus 2x] Kickasskev:
Installing 1.6 now, lets see if it works

Rebooting...........

I'm in thanks now i'll put 1,8 on :-)
[LG Optimus 2x] salisbury_steak:
I'm with you man. I really appreciate Topogigi's work on this ROM. So much so that I'd rather wait for his go signal before I "supercharge" my device. Or I'll wait until he integrates it into the rom. As long as we inform him, I'm sure Zeppelinrox wouldn't mind. :D

My previous phone was a Milestone, so I was actually able to witness how the supercharger grew from just a bunch of AKMO (AutoKiller Memory Optimizer) settings, all the way to a full blown flashable zip. Still, I'd wait for the ROM dev to check it out and make sure it blends well with his tweaks.

And about AKMO and Gingerbread, I remember Kabaldan (original developer of CM6 and CM7 for the Milestone) saying something that GB uses a different set of OOM parameters (GB uses 8 groups as opposed to Froyo's 6). This means that AKMO's 6 groups cannot make changes to all groupings of GB, and worse, may conflict with some of the ROM dev's optimization tweaks.

[LG Optimus 2x] sorcio91:
The procedure is:

Wipe everything-> install 1.6 -> do the first config -> install 1.8 -> done

Do you did all of this?
[LG Optimus 2x] Kickasskev:
HAHA New market on v1.6 andthe old market on v1.8
[LG Optimus 2x] Topogigi:
Not a case ;)
[LG Optimus 2x] salisbury_steak:
If I'm correct, Topogigi did that on purpose. A lot of people were getting "you're device is incompatible with the app" error messages with the new market. With the old market, everything worked fine.
[LG Optimus 2x] lucfig:
I came from milestone too! Everything you said is applicable for me too! :p

I remember Zeppelinrox arguing with Kabaldan about this!

Anyway, you see I am not alone in thinking that the best is to not tweak the rom too much. Topogigi knows what he is doing.
[LG Optimus 2x] lucfig:
And the new market is automatically installed after the first reboot.
[LG Optimus 2x] felipemadox:
1) Full Wipe

2) Install 1.7

3) Do first configs (login with google account)

4) Reboot to recovery

5) Install 1.8 without wipe anything

I don't know the reason but that could be more simple...

You might need to read a few pages back man. It was raised multiple times, and Topogigi explained that 1.6 has certain optimizations that are more stable and are better suited to be the base of 1.8 for new users. :)

positive news: after trying the steps of your gps-faq the 3rd time i was willing to give up. but this time i waited longer. for 5 minutes with at least 4 satellites and no fix "gps status" found 7 satellites and locked it! but no constant lock, connection is lost and found again, still o.k. after all a great step forward:)

what i did is:

- use fixed services.jar from modaco gr3

- set gps on and reboot (?)

- follow your faq (thanks for that!!!)

settings that worked for me in gps test (hidden menu):

- "get position" settings: session type "tracking", oper mode "ms-assisted"

-> important! waited a least 5 minutes for the first lock ("Dont't worry, carry on....";))

- after that gps locks faster

but: i tried different settings after that in "gps test" and still got gps locks. perhaps changes only happen after reboot.

how much fuel needed depends on the engine RPM not the speed of car.

how much energy needed depends on if it could run in its optimimum state.
