Would be interested in hearing your views about some of the tips, especially the CPU Clock app as it is something that I would normally stay well clear off.

But.......maybe interested if I can save a bit more battery life.

Thanks for the tip - using the SetCPU app and I must admit, the results are pretty impressive. Phone at 75% remaining after 8 hours.

Anybody care to share their settings that are being used?

My profiles are:
Charging - 998 max; 245 min
Sleep/Standby - 245 max & min
Power (<20%) - 768 max, 245 min

Set on boot ticked. Max frequency 998400; Min 245000.

Happy bunny at moment

Anyone try getting all of these and trying them out? Sucks that we have to spend money on apps just to make the battery longer. Is it really worth it?

You would think google will roll some of these features into a futue update of android. Compelling reason to root if this does not happen in the coming months.

so i did this and i dont see much of a difference. I may not have the best task killer but it does the job. What about my Lookout Security program? Does that drain the life out of my battery?

tempted to root for this app alone... battery life is pitiful and needs all the help it can get...

anyone have any major issues after having rooted and installed setcpu?

Well, I rooted, am using Cyanogen 5.0.4.1 & have SetCPU installed and working (only on the Profiles bit).....

While I had some initial confusion as to some aspects of the UI and setup, now, all works sweet.

At 14hrs, I have 32% left of battery, after having made 50 minutes phone calls and Wifi switched on and connected most of the day in the office. Plus bluetooth connected for 30 minutes. Plus the usual texting, googletalk, bit of surfing and accessing RSS news feeds thru NewsRob.

Combined, the Cyanogen ROM & SetCPU are a pretty powerful combination IMHO.

Wife's giving me a slap - got to go. PM if you want to ask any more questions>.......

finally rooted... in part for this, in part to finally try out the Desire ROM.... so now that I can run setCPU, we'll see how well it helps in improving battery life... I have no doubts that it will help - the Snapdragon is a battery hog - but hopefully it will be noticeable...

Im not saying everything in that video was fake, 13 hour run time is normal if you dont use it. When he showed what used his battery, I immediatly stopped the video because he is lieing. He didnt have wifi on the whole day because the battery usage would say different if he had it on the whole time. He was not texting/using 3g at all, again if he was, his usage would say different.

Yes I do have a droid insted of a nexus one, but android 2.0.1 and 2.1 arnt THAT much different. And im pretty sure his ROM doesnt block items from his battery usage.

The general info he gives is good, but he didnt use his phone much at all the day he recorded that video.

I didnt even watch the vid... anything that can help throttle the cpu is worth a try to improve battery life... droid has great battery life but not the Nexus so it needs a bit of help ;-)

I also use Timerrific to help with battery life per usage patterns at different times of day.

Try JuiceDefender, or setting profiles. They are what I use. I'm not sure how well they work, but it must do something. Yes, granted the Droid probably has better battery life, but I unplugged 9 hours ago. On the phone for 30 mins, plus time in the market, some on the internet but not much, auto brightness, and trying out a couple of apps, im at 80%.

Battery Use:
Voice Calls: 54%
Phone Idle: 12%
Display: 11%
Cell Standby: 9%
Android System: 4%
Bluetooth: 3%
Android OS: 2%
Beautiful Widgets: 2%

Today, I had mine charged at 100%


I unplugged it.

After 3 hours I was down to 50%

Battery usage showed Beautiful Widgets used 67% because for GPS running for 2.6 hrs.

No wonder I have been getting horrible battery life lately.

I'm curious tho.. I have to root to get setcpu and the apps that REALLY make a difference in battery life. But is just rooting the phone enough? Will the apps have the rights they need to work or do I also need to flash some stuff?
Because I'm new to android and I don't want to be changeing it all this quickly. But I DO want the batterylife of setcpu!

Probably a dumb question, but is it totally necessary that your N1 be rooted to do this? It seems as though all of the apps are in The Market when I check...and my phone isn't rooted.

So if I install these apps, and I'm not rooted, why don't the steps from the video work???

Can someone explain please. Thanks so much!

That's because the "beautiful smaller home" widget uses My Location services to get local weather reports. Click on the weather part of the widget then untick "Geolocation", and make sure you put your correct city in for your default city.

You can configure the My Location services (push the home soft button, then the soft menu button, then Settings, then Location & security), so that it users wireless or GPS to determine your location. Having GPS enabled means more accurate tracking of your location, but at the cost of battery.

The apps which require root will install from the market fine, but they will not run. When you go to run it, it will tell you that must run it on a rooted device.

Honestly, I don''t see much difference after setting up my setcpu profiles. I have it set to use only 384 as the maximum in sleep/standby, though admittedly, I do not have much running in the background which would cause it to ever to use more than that even without setcpu.

Are you set to 'userspace' for the CPU Governor setting? (note: each profile also has its own CPU Governor setting)?

Mine was set by default to 'userspace' - and after seeing the below article, not using it anymore... apparently it doesn't work (it's supposed to let the apps decide the CPU speed...)

Android Rooted: setCPU and CPU Governance

After reading this, changed my main Governor setting to 'ondemand', along with that of the charging profile, and setting 'conservative' for the sleep, power < X% and failsafe profiles...

modded my profiles a bit... figured i'd drop the charging max cpu speed a bit, since when it's charging, it's already getting a bit hot, and throttling down a bit will allow a bit quicker charging I figure... these are all just guesstimates, by no means what I'm telling anyone to use... it's just what I'm trying...

Default/Main: 998 max, 245 min (Governor: ondemand)
Charging: 806 Max, 499 Min (Governor: ondemand)
Sleep/Standby: 384 Max, 245 Min (Governor: conservative)
Power < 15%: 499 Max, 245 Min (Governor: conservative)
Failsafe (batt > 45 C): 245 Max, 245 Min (Governor: conservative)
