LG GearBox for Optimus 4X HD [V1.2.1 with Power saver]

---

This application allows you to control cpu speed and number of active cores.


Features
- Help extend your battery life.

- Manually control CPU speed and active cores

- Integrated with Power saver option in system settings.
Whenever your turn on Power saver, cpu and active cores will automatically adjusted.

It uses undocumented LG API, tested on stock firmware version 10C.

No root required



Remarks
1. Try it at your own risk.
2. System instability reported with 2 active cores. (Original LG QuadGearBox)
3. The 3 cores active option does not work. I don't know why. I leave that option to test by yourself.
4. This app has been tested on rooted phone. It should work on non-root phone, need some test please.

Bugs
Sometimes it just doesn't work. Reboot phone will fix it.

Note
V1.1
initial release

V1.2
Activate by Power Saver

V1.2.1
Fix incorrect popup message.

Usage
Open LG GearBox
Choose CPU Max Speed and Active Cores then click Apply button

Testing it with my unrooted phone.
Setting clock to 1100, use 2 cores.
Quadrant benchmark then drops to 28xx (before is 47xx)
So I guess this app worked.
Let's see next if this setting have effect in battery usage.

Thanks for testing.
I will edit the post for no root requirement.

app works as it should, but i don't think that it will have a big effect in Battery usage, the Management for the cores is quite good and
quad is used not much, also the core's itself are not the big drainer's.

If we have full access and custom Rom's/Kernel's - than we can expect power savings ....

Underclock does improve my battery life and also less heat.

V1.2 will be more useful by Power saver trigger.

yeah, i misspelled that, underclock surely will improve, but i think reducing the cores will also give us more juice, but not so much i think,
but i test the new version now

Be careful not to set clock too low.
When entering power saver mode, the phone suddenly lag heavily

change to 4/1500 from 2/860, device turn off itself.

I have another request.
Please make a preset list for combination clock and cores, so we can make a quick switch setup.
better if the list can be customized.

Will there be any problem if i uses quadgearbox in conjunction with this? or does this serves the same / better as quadgearbox?

Nevermind, i uninstalled QGB and using this instead
