This guide is just something to give you choices, anything you do it's your job, but just get some inspiration;) WARNING!!! I am not responsible for anything you do to your phone, just try not get too fuzzy with it, or you will brick your phone!!! Most the thing here will be for rooted phones, if something not working don't blame me, blame GOOGLE... This only Applies to stock GB and CM 7.1 by mik_os, any other ROMs may not be supported, sorry.
Any extra info and apps are welcome
* - No danger, definitely go for it!!!
** - This may make your phone unstable, but if you find the solution in time, you are fine...
*** - May make your O1 un-start-able...
**** - Can brick the phone, can destroy it forever!!!
Install CyanogenMod, it will save at least 100MB of your internal storage(as all apps are on ROM, LG apps are on internal memory in stock).
Also, may do much more better things to your phone, but be careful.
Try custom kernels by franco for overclock!!!
First of all, lets start with the CPU****
I will tell the frequencies, and what I recommend for, any other advises are good, for any frequency, or atleast the major ones(122-480-600-729-768-806-864)
122MHz** - Lowest, but there are some things:
- Use this if you don't use your phone, only for rare talking and stuff...
- If you have 2% battery drops in 2 mins after you turn the screen on, this is the problem of 122 min...
- If you use your phone more than 1 time/hour (no matter how much), don't use this as min...
245MHz* - Avoid it at all costs, it does nothing good, takes same battery as 480, but it is slower, finish tasks slower, don't use...
320MHz* - This is not good for anything...
480MHz* - My favorite, 90% of my use, will save battery, fast response, maybe it will work as max a bit, some apps work like a charm on 480
- Anyone using the phone for anything else other than calling... this is the best!!!
600MHz* - use it if no need for OverClock, as I noticed, only Angry Birds and Facebook app gets boosted...
729MHz** - Best Overclocking for battery, will not affect any of your phone, battery is as much as 600, no way you shouldn't use it, no heat up also!!!
768MHz** - best performance without affecting hardware, it will heat up a bit...
806MHz**** - Last one that will not burn it in 5 minutes, I would not go any higher...
864MHz**** - If this works on your phone, it is 100% new and 100% perfect!!!
MENTIONS, VERY IMPORTANT: It depends on your phone, manufacture errors, your phone may go stable @864MHz, or it may not go higher than 600... mine goes at 768MHz, any higher gets me KP...
If you don't need profiles, just get No Frills***
minmax - like the name, goes to min or to max, it is horrible!!!
Scary - a modified conservative, a bit weird... try it you may like it, better at battery than conservative, worse at gaming, non-gamers, try this!
SmartassV2 - Good, try, great... a better version of smartass, use this if you have it, great for fast gaming, but not good for long use...
SavagedZen - WTF IS THIS???????
smartass - it changes the frequency very good, it really is smart, see v2↑
conservative - goes up and down in stages, not 122→729, but 122→320→600→652→…, really good for long uses and short uses, not taking battery like others, but it has a lower start when gaming, lag in 1st 2 minutes, but then it is no more lag, tested on "Diversion", a really cool highend game.
ondemand - this is what you had when the phone came!!!
userspace - WTF IS THIS??????
powersave - keeps at minimum frequency...
interactiveX - modified version of interactive, which goes to max in second... it is same as SmartassV2, a bit stabler on my phone.
performance - stays at max...
SmartassV2 and InteractiveX have build-in sleep profiles, it saves battery when standby-ing and best performance at gaming, while scary gets you best battery and a usable phone, and conservative the best performance/battery.
Next, VM heap(RAM allowed for an app):*
This will take more RAM, but will boost the CPU and more things...
On CM7, go to performance settings-VM heap
On stock ROM, install VM heap tool from the market...
Set it to 32MB*, this is already done in CM7, but on stock ROM it is easy and then then BOOSTED...
24MB will slow apps...**
48MB will fill the RAM fast, making system autokill kill too fast...**
OR just change the value in build.prop
Use a simple launcher, that may save battery and use low CPU... Here are my recommends:***
- Looks a bit like LGHome, and takes less battery
- Very smooth, look at the video it has on the market...
- It really is fast response and quick launch, a new experience
- Very simple, smooth and
- Very good, my personal favorite, will save battery and keep options, will need to be updated if ICS comes, tho...
- Smooth, but no horizontal drawer...
- I hate that this is hard control, not very smooth, YOU have to chose it, but if you tried more, you will see it is not the smoothest, not the most customisable, but a pretty good combination...
- You can get used to it, but if you used LGHome for more than a month, you won't need this, you will quit it!
- This one gets updated, and really fixes the bugs it had... it is not an usual one, but minimalistic, like it says
- Most of the big launcher won't get updated anymore, abandoned...
- This one is good, but it is not exactly smooth, but power save
- With the right combination, they say you have it smooth, I didn't
- Did 2 factory resets because of the corrupted data after a few glitches that made me remove the battery...
- DO NOT SET default if you want this, dangerous... only thing that did something bad when I was not rooted, got me bootloops((((((
Watch out the setting you enable, maybe you don't need all kinds of gestures, anything you don't use, DISABLE!!!*
APPS TO USE OR NOT TO USE, YOUR OPINION IS BETTER, THIS IS JUST MY ADVICE:
NO TASK KILLERS(ATK, ATM, TasKiller). Use minfree, set the values you need, the other tweaks you need and enjoy!
Juice Defender will only help you... really when does it help?????
Link2SD - easiest way to manage, freeze, uninstall, move2sd, any app management that requires root, except backup!!!
Just uninstall any app you don't need!
Data on Demand - Really good, try it
Freeze system apps (Link2SD above!!!) with ugly UI and slow, like the Browser and Gallery (YOU MUST), but get a better app before that, with all those missing functions...
Replace Gallery with QuickPic and Browser with Dolphin, which is the only one with cool UI, fast startup and FULL, Opera Mini and Mobile are NOT full, but they are fast
If you want to save your eyes, use Screen Filter*
Yahoo Mail and Gmail are huge hogs!!! If you don't need instant notifications, use stock for that, it refreshes automatically when you start it, takes 2 seconds to refresh, and no battery lost...
Disable profiles in SetCpu if you don't need, that takes battery too!
Use Autostarts, this is your problem, your apps, good luck, but watch out...*** If you want, google autostarts.apk, I got it that way
Disable unused settings, never use high quality in games and apps, that are made for hdpi, O1 is MDPI...*
Don't use wifi when it is not there, just hogs battery, I know some people use it everytime, everywhere, just get it on when you use it, or if you have at home...*
GPS* - This only works OUTDOOR, don't enable it in the house
Get brightness to minimum, will save your eyes and trust me, get it to max in sun and you see it perfect, get it off when at home and see it the same...*
AutoSync* - Disable sync for crappy apps, some things just sync without working at all...
Data* also takes lot of battery(very much, actually), so disable it when not in use, if you want it off when screen off, use Data on Demand
Also, empty your screens, don't use 10 widgets per screen, I use 1 and I am happy, they don't inform you that much, you know...
*Disable setting you don't need( like the high quality images in cm7 menu, what is it good at Optimus one?), eg: I never use gestures, I type Facebook faster than making an "f" in gestures, and that takes some of the CPU, disable everything you don't need or that doesn't help!!!
Angry birds(not seasons and Rio, only the classic) has an option to disable the background, that will make it 2x faster...
Disable history you don't need, flash when you don't need...*
ROOT O1 worked for me without a hard reset
CM7 by mik_os

Kernel for stock FroYo and 6.5.x by mik
New baseband(if you want cyanogenmod and you upgraded to 2.3)
