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.

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

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.

Actually LG Hidden Quadgearbox is where I started to look in LG API. Basically, use the same API to set 2 cores active.
I think freeze/restart is the reason why LG hasn't release it in official firmware and that's why we need this app
