You have a lot of knowledge, this is obvious but you're unnecessarily harsh (mean).

It's boring but's it's a legitimate question because people still make inaccurate conclusions about CPU and battery life. Those of us with some knowledge can really help those that are trying to understand.

#2 above is correct. But the question remains, does a forced lower clock speed ceiling have an effect on battery life? It could do, of course it could, but without a baseline and a control environment it's impossible to prove either way. I suspect the OP is simply looking for subjective opinions.

And on this basis I offer:

The CPU only has a material effect on battery drain when it's being utilised.

When the Nexus CPU is not required to work it idles using the lowest power possible

The radio (network) interface is the second most demanding element of on your battery over time (next to the display). Although the CPU peak demand is higher than the radio.

SetCPU does not impact radio battery use.

SetCPU can not have a positive effect on battery usage if it's using more power to run it's clock cycles.

SetCPU can force the processor to use less power (wind down speed).

Slowing the processor means some tasks will take longer to perform.

If those tasks require a high-drain elements (display, radio, WiFi or BT for example) then it's counter-productive (battery wise) to slow them down.

However, because CPU power consumption does not have a liner relationship to clock speed, then some tasks that don't use high-drain elements will consume less power to complete.

So, whilst it's unlikely that your battery life will benefit from the use of SetCPU alone there is a chance that it will.

SetCPU is a fantastic app designed for overclocking, the profiles are niche facilities that may offer battery benefit to a narrow range of users.
[Nexus One General] wondercoolguy:
Hey djmcnz thanks for the indept look at this app but more importantly thanks for showing respect to those of us who are just learning. We all have to learn information at some point and there are people that forget that at one point some one had to tell them.
[Nexus One General] THATTON:
Thank you for the clarification on that! Djmcnz-that was exactly what I was looking for in terms of an answer. I really appreciate you taking the time out to explain everything for me and anyone else that may have been curious.
[Nexus One General] faraz1992:
Don't know why you're so pissed off by a thread...

1. Not a very big issue. We have mods here to take care of this.

2. I don't know if SetCPU affects battery life or not but similar thing on a PSP device does increase the battery life. I have tried it on my PSP and setting the clock speed to the lowest acceptable level (depending upon what you're doing) does help maximizing the battery life.

3. You're absolutely right here.

4. Don't know what to say man.. but being a little humble doesn't hurt....
[Nexus One General] charnsingh_online:
I never meant to be rude. I always get pissed off when people post in wrong sections Seriously. If people post in right section it just frees up moderator time. And about CPU nexus CPU has same voltage for many frequencies like 998,960 have same voltage. Going so down doesn't mostly benefit. So setcpu is only good for overclocking IMO. Display uses most of the power along with radio n CPU is one of those in middle of usage maybe 3rd or 4th. So underclocking will give a big battery boost is just a placebo. Atmost 10 minutes more is what underclocking can provide. N its not worth sacrificing the performance. Go for something underpowered if u want to underclock IMO. So setcpu serves more purpose of power than battery

Personaly done many tests and the result was:

Test config: WiFi tethering all the way, screen 100% Playing video all the time 2G only

4:10 @ 245Mhz hard

3:30 @ 998Mhz hard

No use actually - using N1 on 245Mhz is impossible - too sluggish.

SetCpu is ussefull:

1) If u have OC kernel to set OC mode for games like Asphalt

2)For letting android vary frequence ondemand instead of 998 all the time

3)For downclocking while in sleep mode (why use full power when u dont use it?)

4)For using Failsafe profile, to prevent battery and hardware damage.

That's all.

No use trying saving battery setting profiles like 100% - 998, 50% - 576, 20% - 499. This is useless.

On UV kernels the same thing +\-30 minutes battery life. And UV kernels themselfs dont give segnificant battery life increase, only lags and unstability ti system.

Dont believe me try yourself - Create yourself some actions fo testing and repeat them 2 time (Min cpu and Max cpu) on any kernel. Results will be very close.
[Nexus One General] djmcnz:
The CPU steps down to it's minimum speed by itself. It never uses more juice than it needs to.
[Nexus One General] SeriousX:
As far as i know, it is always at maximum, but maybe im wrong and you are right - then theres even less sence in this app.
[Nexus One General] rori~:
Agree completely: SetCPU is only useful with overclocked kernels!

I tested couple of days with & without SetCPU on default kernel and had no benefits to better batt.life.. had only negative effects on WiFi & Launcher.

I will use SetCPU, when I boot an overclocked kernel again.
[Nexus One General] jlevy73:
Cheers DJ, excellent explanation.
[Nexus One General] schahr01:
Like it was mentioned, this topic has been discussed on several kernel threads. I decided to uninstall setcpu after reading some comments on intersectRaven's thread. It's a non-OC kernel, I honestly don't see a difference in batt life without it, been a week since uninstalling.
[Nexus One General] Gslick:
If you set the right profiles, I save very noticible amounts of battery. And yes I go a full day of moderate use with setcpu + profiles enabled, I have over 5 enabled. While charging (which seems to charge my phone so much quicker), one for battery under 25%, one for when phone is asleep, 1 for if phone gets hotter than 50C, etc.
[Nexus One General] techlogik:
I decided to spend the buck or two for the app.

I am glad I did.

This app really helped with battery life. Running a Desire Rom on the N1 and my Exchange full syncing all day along with some other stuff was just killing the battery.

Now, I can set the Profiles and down throttle the processor while running task at several percentage levels of battery life.

This helps greatly, and it still much faster than my iPhone 3G even at 500-768Mhz speed set.

Also, while sleeping, it throttles way down, even when asleep, I suspect when Push mail is working, the slower processor is in effect which also helps, have that set 1 click above the bottom.

I could go 2 days on my iPhone with normal usage. I am at 35% left of the battery with the cpu settings at just about 11hrs now. I think it has helped to get me through the day without sweating it, maybe 20% longer?

Guess I would have to test a normal day now without the setcpu to confirm.
[Nexus One General] D200P13:
can someone give me information on how to setup my phone so when it goes to sleep the cpu is about half and when its wake to go back to 1ghz? i just want to try and cut it to half when its idle. thanks!
[Nexus One General] djmcnz:
It runs at its lowest when it's idle so there's no need to force it down... well you can't force it down. You can only cap the ceiling.
[Nexus One General] D200P13:
oh ok then theres no need for me to get it since i dont wanna max it out or nothing. would of used it for that reason only. thanks!
[Nexus One General] Marine6680:
Seems the only time set cpu actually helps battery life is when you have apps that run in the background even when the phone is in standby/sleep mode. (like location tracking apps, music players, etc) These apps may cause the cpu to run at its highest speeds, when they may not really need all that power. Setcpu can be set to not allow the cpu to throttle all the way to max when the phone is in standby, and therefore saving some battery. So if your not running apps that do a lot of work in the background, it may help.

Also, with the upcoming 2.2 update having JIT, and having a pretty large performance increase because of it; you may be able to underclock the max cpu speeds while still getting good performance and maybe better battery life. But it could be unnecessary if cpu load decreases overall and the 2.2 update takes this performance increase in mind with its default throttle curves. One would think with increased OS efficiency, overall cpu load would drop. I could be wrong though.

I had Cyberon's Voice Speed Dial working well on the Tilt and Diamond, but I can't get it to work on the Snap. It keeps saying "no trained voice tag" and kicks me out. I don't even have the chance to set it up. Does anyone else have similar experience and possible solutions?
[HD Mini General] HampshireIan:
Hi folks,

I'm leaning towards getting myself a HD Mini now. I've read enough about my other two choices of Legend & Desire to know that the battery life I can get from the Mini will be much more to my taste.

So, firstly is there an extended life battery for the Mini that anyone can recommend. to try to get even more power (I know it seems weird as i've made my choice but no harm in checking) - obviously one that's the same size and doesnt need an extended cover?

And what do you guys use for screen protection. I know there are loads of plastic protectors to cover the screen but they all seem cheap and tacky. I did originally have an iPhone and the one I bought from the Apple Store was amazing. Very thin and flexible. Any thoughts?

Thanks very much

Ian

Clock

Where did you get such an amazing clock? Do you have a way I can add it to my ROM?
[Hero CDMA Android Development] Konikub:
That clock came from a theme from Gomorrah...and you can find it in the themes thread :) I believe he built it for DarchLengend.

....my guess, is you could flash his theme over your ROM.....or you can pull the clock from either his theme or this ROM :)
[Hero CDMA Android Development] tyrnight:
Im trying out the new rom.. It looks great.. and the only issue I have with it at the moment is it is really sluggish.. not sure why.. but from the start it lagged a lot..
[Hero CDMA Android Development] Konikub:
Hmmmm, really zippy on my end. Have you tried rebooting...and/or setting the autokiller + spareparts transistions. Those both help out greatly in speed of window transistions and whatnot.....I've noticed anyways. Hope this helps :)

Reboots are a computers best friend...lol. However, they do not always solve the problems :p
[Hero CDMA Android Development] tyrnight:
Yup done all that .. as I do on all your roms. :) I have autokiller at aggressive and transitions at fast...

rebooted several times.. and its not syncing... Ill give it a another hour to see if its just doing some BG stuff..
[Hero CDMA Android Development] Konikub:
Sometimes it does take a while...for me once, it took over night to sync. I did not sync my FB up with my contacts as I don't like to. I like the pictures "I choose" for my contacts....not what they like to choose, lol.

.....So if it does not work, I won't be too upset. However it works like a charm (for me) in Aloysius, and that is what I'll be running as my daily....as I am more a fan of Sense UI :)

If it's a crazy hot issue with this ROM, I'll dig deep and try to find why it's not syncing...provided we find it not to work.
[Hero CDMA Android Development] tyrnight:
OH haha.. sorry.. It synced just fine to FB and all my contacts.. I was just saying that it wasnt doing a sync while it was running slow..
[Hero CDMA Android Development] Konikub:
LOL...gotcha!!! Well, we now know that FB syncs with contacts.....now we just need to find why is laggy for you :)
[Hero CDMA Android Development] tyrnight:

Alternative to bookmark widget?

Hey I first off wanted to say that I love the Rom...I came from Damagecontrol which I also love but I wanted to get away from Sense. Now I find myself missing a few things from sense but nothing major...

The one thing I miss the most is the bookmark widget does anyone have an alternative to it. I know you can do a direct link but it just doesnt have the same effect. Also does anyone else have any other cool widgets that are gems out there. I use Mixzing large art as a scene as well as the fb and I used to use the bookmarks...I am now down to 5 and I need an extra widget to fill...I cant do 4 scenes because I just find it awkward LOL.

Thanks in advance to anyone with some input.

Dl "Live Bookmarks" from the market. Its a live bookmark folder that when opened, shows your bookmarks in list or grid view. Its nice because its "live" so if you add bookmarks it will update and keep them in order without having to move things around. Also Dolphin Browser has a bookmarks widget, but its only 3x3 and i'm not a fan of it. I'm surprised that someone out there hasnt made a sense style bookmarks widget for the market.
[Hero CDMA Android Development] anthromatt:
Be patient. If you don't wipe first, it will stay on the HTC screen for 5-10 minutes. If you do wipe, I have found it only stays on the HTC screen for a couple minutes at most.

I think that means it is working. The ROMs are not ODEX'd so they take up more space. Before I started using A2SD I would typically have less than 45MB free after flashing a 2.0 ROM. Now I have about 80MB free.

[Hero CDMA Android Development] DarkPhoenix:
Well the only other thing I can recommend is to boot to recovery, do a factory wipe, wipe the dalvik cache and wipe the ext partition of your sdcard. Flash the rom and then flash apps2sd over that (I've attached the A2SD that I'm using below). Reboot the phone and reinstall your apps. Let me know what happens.
