Stock kernal

---

Well I downloaded cpu master (free) to just mess around with my photon, and come to find out, the governor for the cpu is set to performance, but gave me the option to change it to powersave, so I switch it and I'll report back to you guys and see if I've found the holy Grail to even better battery life

That's awesome

Wait until I or another dev gets onDemand governor enabled...

I have SetCPU, and honestly, I haven't noticed a huge difference in battery life with powersave unless I seriously scale the CPU back to like 300 mhz. Then it'll last a while, if I don't do ANYTHING with it. For example, when I'm sleeping, otherwise, it just makes the phone laggy and doesn't seem to help enough to make it worth while. Just my opinion from screwing with it.

The general consensus regarding over/underclocking when I had my HTC Hero was that overclocking would save battery because you could get what you wanted done faster. If you scale the CPU back massively while it is set to sleep, however, you will save a lot of battery.

well, i don't know about your phone or what else you have setup, but my phone didn't lag and it seemed to help, i currently have my evo 3d active so my photon just sits there, so i can give a good feedback of idle time, but i can tell you after switching the governor, it went down 1% in 2 hours, now i say that's an improvement, so when i get back home i'll really give you guys some feedback

P.S. with any phone i had that had a fully custom kernal, i always used conservative governor

Well, perhaps it's just the apps I have running then. As I said, when it's set to sleep, it works pretty well with the powersave mode, otherwise, doesn't seem to make any real difference. Guess it's different for everyone cause of the **** they're running on their phone.

You know, I've never bought into this argument. To me, it is like saying that if I drive 100 mph I will get there faster, so I use less gas....which we all know is not how it works.

Maybe the physics are different for processors then they are for engines, but I think there is probably a happy medium somewhere. And I have a feeling that the manufactures really take this into consideration when they develop the kernels and ROMs. However, I might be wrong.

This is by no means an effort to discourage your awesome work. Everyone gets different results, but stock always seems to have the best battery life for me once all the bloat is gone. However, custom kernels do perform better. That is the trade off, in my opinion.

Lol honestly I never bought into it either. I was just posting was the other devs at the time said. Even using an OC kernel, I never overclocked my phone.

Interesting...I hadn't thought about using an OC kernel and underclocking it back to stock. I wonder what that does, if anything, to performance.

The other concern that I have is that overclocking typically means more heat, which means more battery use... Just figured I would throw that out there too.
