[Galaxy S II General] CamoGeko:
Configurations comparisons, battery run results.

My recent battery run:

​

This was on:

CheckROM V6 + N.E.A.K. 1.4x + MagicConfig v0.3.2 + V6 Supercharger

As you can see in the screenshot I was on 50% battery at that time, so by the power of addition we can conclude that 6+ hours screen time is very much possible and isn't a myth. :D

Massive thanks to It_ler for conducting the following comparisons (28-02-2012), please read the whole report carefully to avoid unnecessary questions.[/SIZE][/U][/B][/CENTER]

Results for SpeedMod / Phenomenal / N.E.A.K. / Siyah / RedPill / stock kernels

Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.

For all custom kernels, I was running on Frankenstein XWLA4 ROM (Modem: XXKL1).

For stock kernels, I was running on the corresponding stock ROM.

Always using the Samsung's standard / stock 1650mAh battery.

For Siyah, as it has many, many configurable settings, I have changed nothing - just default settings.

For N.E.A.K. I tested VR schedule, Lulzactive governor, only enabled sched_mc and the rest unchanged defaults.

For RedPill kernel, I tested completely default settings (deadline / ondemand) without any change.

For RedPill (MC, noop/conservative), I tested geko95gek's MagicConfig v0.3.1 settings with noop / conservative on 200-1200 MHz (no UC or OC, only recommended/safe UV).

For RedPill (MC, dealine/sleepy), I tested geko95gek's MagicConfig v0.3.1 settings with deadline / sleepy on 200-1200 MHz (no UC or OC, only recommended/safe UV).

For RedPill (sio/conservative) kernel, I tested completely default settings, only changed io sched to sio and governor to conservative.

Just tested RedPill rev1.3 with different io sched / governor combinations (and geko95gek's MagicConfig), and added its results.

Here are my current results:

(*) In order to get a value, which allows to compare test results with different screen on times for mixed usage battery tests, I tried to „normalized“ the battery loss per hour with the following formula:

loss*(1-screen): battery loss in % (per hours) * (100% - screen on time in %)

So, it would be the battery loss in % (per hour) for the screen off time.

That is how a kernel with the same battery loss per hour will get a better/lower value, if it has more screen on time. (And the other way round.)

RedPill rev1.3 has got best battery savings with sio/conservative on my phone, even without any additional UC/UC, etc.

Subjectively, it feels a little bit laggy/not as smooth as in other combinations (e.g. sio/hyper).

So, my first impression of this kernel was proven: Very stable kernel which is highly configurable to fit every demand - for performance and battery life.

Thanks again pongster for that great kernel.

And thanks to geko95gek for his MagicConfig which gave me enough confidence to test out some UV, io sched and governor changes.

Looking forward to test new versions of that kernel ...
