What is powerhal? I'm trying out slimrom for the first time and would like to know what is different from the kernel you implemented on to slim than the one that is the stand alone kernel.


PowerHAL is a ROM-side hw power control library. Faux added communication in there to let intelliplug know when we go into low power mode (intelliplug will then go dual-core) or on the orther hand it will power up cores when video recording or HDR pics are taking.

Default kernel in SlimLP (my builds as well !!) for Nexus 6 is leankernel, so just check out imoseyon's thread on xda, and compare to my changelog.

In short, both kernels are pretty different :

- imoseyon prefers to keep CPU management stock but upstreams Linux version and merges CAF updates etc.
- I prefer to keep the kernel stock but rather add features (like my CPU hardlimit, intellithermal, intelliplug etc.)

But we also share stuff like the color calibration etc.

Not saying anyone of them is better or worse, it's a different approach. And imoseyon's kernels are most definately excellent ! ;)

PS: 5.1 will come when Slimp 5.1 will be ready, the kernel is ready, but I need the ramfs to go with it for the boot.img.

Ohh i see. I thought this was a type of added features that can be messed around in settings.
I will try slim rom for a couple of days and see what kind of battery life i get.

Keep me posted here, would be interesting to have a feedback on that regard as I don't ofter get to use a battery cycle normally, always falshing kernel or ROM so the battery life is more or less ruined by that ;)

When I get through a full day without messing, I usually get a 5h SOT over 18h with all on (bt, wifi, mobile data, sync).

Will do yank. I dont use bt at all but wifi,sync and mobile data i do. I will give you a better battery stats screen shot of what my battery life looks like.

Also, you built the slim rom for shamu? I see that your a developer. I did not know this.

I've started ROM side stuff this year, 3rd od January, must have been bored that day :D

Best move I've made after starting kernel dev'ing, it's pretty fun to code ROM side stuff. I do contribute to Slim, as that's the ROM I've been running for the longest and on most of the devices I've owned.

That is awesome! I will be testing your builds then :).

@yank555 i decided to test your rom and kernel for battery life in two modes.
1st mode medium brightness, wifi,data,sync, all on with my normal heavy usage.

2nd mode everything the same as in the 1st mode but with screen turned to grey scale.

I decided to try grey scale because ik that the s5 had this option when it was down to battery saving mode.

Tonight i should give you results. I am a very heavy user lol.

Here is my 1st mode battery life.

So far from my last charge. On grey scale.
:) seeing better results for battery life in this mode.
Would be awesome to implement this in the rom as a battery saving option after a certain percentage.

What certainly has a positive effect on battery on a device like the Nexus 6 is a dark theme, since the darker the screen, the less the amoled will draw juice from the battery.

Have you given one of the dark overlay themes a try ?

Of course it's also a question of liking dark os vs. bright LP material style.

But I suppose it would be possible to enable grayscale mode on battery saving mode, although grey = all three base colors on, which might actually use more juice than the same brightness in let's say in just red (= 1 led vs. 3 leds per pixel on = 66% less battery draw).
