setCPU dangers

I get pretty crappy battery life on my poor little N1. Cell standby takes up 49% and phone idle 49% when I go into the battery information. I am considering setCPU but I'm scared that if it's changing the clock speed every time I turn the thing off isn't that bad? I mean having the clock speed adjusted so many times, couldn't that hurt the device's life span?

by default on stock it already scales the CPU to conserve battery

My battery life has increased since I've used this program its awesome

Cell standby and phone idle at 49% each isn't a problem if that's all that's been using it. It doesn't mean each one will take up 49% of your entire battery. If you just unplugged it and let it sit without using the screen or anything, then the only thing using your battery is the standby and idle. So after 2 hours or so of that, you might be down to 90% battery, and both cell standby and phone idle are using 49% of that 10% each. In other words, it used up 4.9% of the total battery each.
As for changing the speed all the time, it will not hurt the CPU, as Android already does that for you all the time. When sleeping it under clocks to the lowest, and when you need to use an app, it clocks it back up to full power.

I've been using it for 4 hours and they're both 49% and the screen is only 2%, is my phone defective?

Have you been using the screen during those 4 hours? Like using it to browse or run apps or anything? Or has it just been sitting there for most of the time?

Sitting there mostly. Here's a screenshot I took yesterday:

Absolutely no use whatsoever and it's lost 12%?

That seems perfectly normal. Don't worry about it. It does have to use power to idle there, it is still a running computer, and it also needs to stay connected to the closest cell tower in case you get a call.
When it is sitting all by itself that is all it has to do. Your screenshot shows that in 10 hours it only took 12%. That is very good.
If you used the screen for 5 of those hours, your battery could be down to much less than half, and the screen would be about 90% on that graph, while the idle and standby would be less than 5% each.

I only get 2-3 hours if I'm using it for internet I'm not sure if I need setCPU or of it does it for me
I really wanted a desire rom but everyone goes on about how bad the battery life is on them. It doesn't make sense because the desire has a 1300 battery when we have a 1400.

Ok, that is a problem. When it is idling your phone seems normal, but I am able to get more than 2-3 hours when browsing the web.
SetCPU won't help you that much, well it can help, but it is best to find out why you are so low in the first place. Fix that first to get it to a normal length first, then you can look at extending the normal time to longer with SetCPU and other things.
As for right now, what brightness do you have the screen on, what are you normally browsing on? I usually use it at a pretty low setting because I am indoors, and browse pretty simple websites.
If you use full brightness and watch youtube videos you probably would drain the battery insanely fast.
What are you normally doing when it drains so fast?

30% brightness and just casual browsing, some forums mostly.

Since your battery isn't draining by itself, I don't think it is a rogue program taking the battery.
If you are using 3G with a really bad signal it could do that, as it has to boost the power to reach the tower.
Otherwise I am at the end of my suggestions, you could try reading through a few of the large battery threads until something sounds like it could be your issues. I doubt you're the first person to have whatever issues you have.

I live in rural Canada. I think it's rather mutual that I get crappy service
I would love an extended battery, but unfortunately I know nobody who's actually used one who could tell me how good they are, or where I could even obtain one where I am in Canada.
It's mostly the desire rom I really want though, but the blasted battery is supposedly so bad for it!

I don't think so because I've been adjusting clock/bus speed on my psp for over two years now and the battery life seems perfect and the processor too...

turn off bluetooth, gps when not using. Use a task Killer to end all tasks that you arent using to stop them polling for updates and what not. If using Facebook, Twitter and rss feeds they need to be set to update at intervals >3/4hours otherwise your battery will be absolutely ****e.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.

Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

I agree, but it want a heavy day. When I finally did have 14% left and used tv flash battery seasoned super fast. I forgot, I'm using juice defender too

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.

Barely used phone. Come on.

Display 4%? Is that possible?

I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.

wifi is on = low battery usage, atleast in my experience.

Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.

so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

nobnut said:
100% is the maximum
therefore if we assume a basic scenario with three things using this 100%, lets say:
Android OS - 50%
Display - 30%
Something else - 20%
Total = 100%
Now, if we do not turn on the device's screen, the next result will be something like:
Android OS - 75%
Something else - 25%
Total = 100%
Does this mean that Android OS is now using more power? NO!
What this means is that Android OS has used a larger percentage of the power used BECAUSE THERE ARE FEWER PROCESSES GOING ON!!
In the above example, the total amount of power used has actually fallen.
But the genius folk who complain about Android OS (AKA idiots) all of a sudden believe that Android OS is now using more power and start moaning like a bunch of little girls. As you can see from some elementary mathematics... this is a load of b*ll*cks.

Well, my hat's off to you, sir. You hold the power and the knowledge to be perfectly satisfied with what others don't understand.
As for the one that suggested to buy the Sensation and quotes the display off analogy, what could I say more? He explained how battery works so I'll buy the Sensation or whatever he wants after he explains how magnets work.

You have no apps installed.

I have, only 96 apps though. We all have different usages.

Alright, if the percentage doesn't say anything, why don't they use another measures? Like mAh or other units.
Also these 15 hours WiFi was turned on most of the time. I used to turn the screen on and check Facebook/Google+/browse for 2-5 minutes, every 30-60 minutes. So let's just say the display was on for about two til three hours over this 15 hour period. Compared to 19% for the display I would say 50% is A LOT for AOS/CPU usage.

On a 2-3hr usage, at the AOS is THAT high its pretty much a LOT! Look at how low my AOS is compared to Andriod system, heck even cellstandby is taking up more power.

Nice uptime, but I guess you don't use packet data OR talk to friends/ppl because after all it is a PHONE you have at your possession.
So it seems imo that you AREN'T a normal user like the most of us, making phone calls and receiving them in avg per day, which is about 1 hour (call and receive) and letting packed data being online.
Correct me if I am wrong about this analysis.

Without seeing your wake bar and wakelock stats its hard to have any idea what your phone is doing.
Try using better battery stats(link in my sig) to see if you have any out of place wakelocks.

1 Day 10 Hrs (34 hrs) Battery Life

First things first: A BIG thank you to all of the devs still working on the Epic. This phone is not that old and I still think (because of the keyboard) it's a great phone that I'll enjoy for all of the 2 years I'll have with it. Fortunately, there are others who think this, too and put in the time and effort to make this already great phone better for FREE. I'm not a developer, but I do know it takes a lot of time/dedication to accomplish what they have. So thank you to all of the developers (present & past) for the Samsung Epic 4g
Hello, I'm a lurker none of you know but would like to share my results dealing with battery life on EH06
This is the best battery life I've ever gotten and I have no doubt that I could've reached 1 Day 12 Hrs (36 Hrs) of battery life. A day and a half, I guess I should've waited and let it run out, but my impatience got the best of me.
What I did was flash crawj's EH06 deodexed .tar
I flashed theduce102's (EH06) Copy & Paste ROM Stock Cyan v1.1
I then flashed deano0714's Sculpted v2
I was using the EH06 Modem
Auto-Sync was left on the entire time. Twitter/Facebook sync every 4 hours, contact sync left on.
Brightness left on "auto"
Wifi is left on always, at least until I was out of range.
Personally, I highly recommend juice defender. It'll turn off your data when the screen is not in use which saves a LOT of battery. Sure you could turn it on and off yourself but it's just much easier to use juice defender and have the data turned on for 30s/1min then left off for 30 minutes. 30 minutes is the max for the free version, but I still find it useful.
Take into consideration that I did NOT use my phone a lot.
My usage consisted of about 5 texts/hr, few downloaded apps/updates, few email checks, couple hours of listening to music, 20 minutes on Dolphin Browser HD.
If there's anything else you want to know about my setup, let me know and I'll update the OP.
The colors in the pics are inverted, most likely because of the screen cap app I used

I also got 35+ hrs on EH06 deodexed with the EH06 plus kernel. It was pretty amazing... Didn't take any screenshots though...

A year ago on Eclair it lasted 2.5 days. Complete stock, no root.

this is all nice but I've kinda never understood the point in having a smartphone if you're going to have data shut off the majority of the time. of course most battery life is demanded by data - I'm willing to bet I could get several days of battery life from any build if I put my phone into airplane mode all day but what's the point?

I feel the same way. I used to be obsessed with keeping my data off as much as possible. Then I realized....what's the point. The whole purpose of having a smartphone is to be connected all the time. I say keep your data on and use your device how its meant to be and enjoy it.

yes. plus where are these people that they can't access a wall socket or power cable for days at a time? I can get 14-16 hours with moderate usage by leaving everything turned on. then when I'm home where all those power sources are, I, you know, plug the damn thing in.

What's ridiculous is that these people never made or received a single phone call in 1 to 2 days. WTF? Why did you buy a phone? Go get yourself a Palm Pilot.

I hear ya. I usually get between 10-12 hrs of moderate to heavy use. If your that worried about it bring an extra battery with you. Shoot I carry or have quick access to an extra battery and a charging cable most places I go. I usually don't have to use it, but its there in case I need it.

Having said all of that, that is still pretty good standby time for a GB leak. I've gotten 1 day plus 3 hrs with everything running before. But that's with srf 1.2 and with hardly any use...plus wifi.

I like this post I had my phone shut off on my yesterday at 4pm and it was full at 8am when i took it off the charger. Didnt do much of anything it somehow jumped from 50 to 25 all by itself. Im on genocide 1.1 and srf 1.2

The "all of the sudden" battery fix on ICS

I have been using my s2 only 1 day on GB so i cant really tell you was the battery life good or bad there, but i i have some news for ICS
stock ROM users.
I was actually really depressed by the ICS battery life (i upgraded from GB same day i bought brand new S2), battery life was terrible,
turning on/off syncing, mobile data, gps etc etc helped a bit, but not that much. i still couldent get full day out of it with moderate use.
Again, im on stock 4.0.3 atm.
And then, a miracle.
Let me say right away, i am aware that these types of batterys (i have stock one btw) dont react on this whole "fully discharge then recharge" thing, but i do think now Android ICS as a system does! Cuz it was exactly what i did-i said what the heck doesent hurt to try and i was playing games like crazy when battery was on 10 or less percent so it wld shut down. then, i connected charger and used as normal on charger until it was fully juiced. repeated 3-4 times and what do you know... i now get 50% OR MORE WITH THE SAME BATTERY!
I am not really sure what happend there. Did battery gauge reset? Did ICS "learned" my battery properly? I dont know. All i know is that i am now able to get trough whole day (i get up 7:00AM, go to sleep round 01:00) with only 1 full charge. I dont even bother turning off wifi sometimes when i go out and dont need it.
I have been also reading around the web that some people got the same result. No calibration trys,pulling battery etc etc...just let it go trough few cycles and let system/phone "calibrate by itself".
Not exactly sure if this is a solution, bug, feature or whatever. I just thought it was worth writing to you guys
cheers, loop

why dont u share some screenshots

np mate, but in evening or tomo morning when i come home

Well, you actually shortened your battery life span by draining your battery to nothing, you should probably google what happens when you drain lithium batteries, and how it affects capacity, and not just
dont react on this whole "fully discharge then recharge" thing

You probably did reset your fuel gauge as your phone had no power to hold the gage memory, but you could of saved yourself a lot of battery capacity, by using search and finding out how to reset the battery gauge on the Samsung galaxy s2. Hint* search extweaks and Siyah kernel.
Anyway at least other people who read this, hopefully learn and do it all the easiest and battery efficient way and not

Hope this helped, and for future reference do not drain lithium batteries, whether it is your phone, laptop, ps3 controller. Try not to get it under 50% for the best efficiency, but the more you drain it to minimum charge the faster it degrades.

Did you uninstall anything? Did you change any settings? Sounds to me like wakelocks that were removed more than ICS "learning" your battery.

Take it like this: i upgraded to ICS over GB and did full wipe. First day i installed lets say 20+ apps that i use. mostly utilities,few games.
In this period of "recovery" i only updated few apps, installed GTAIII and Flipboard.
Let me make this perfeclty clear as i stated in OP and as deniso wrote: i am aware of todays batterys and how do they work. i am not senior android user but i know my way around,so as i stated, i know i dident "FIX" the battery itself. But i still think the main problem here is not the battery itself,its how ICS uses it.
However this:

is just... funny. "try not to" ok i get it, but below 50% is when u need your phone the most, should i carry a portable generator with me? no offense.
Please, do not throw rocks at me. I am aware what i wrote, and i am aware that it doesent makes sense with todays batterys and smartphones.
however,i still do have my better battery life, whatever u say or dont say.
Ill make some screenies when i come home.
Ty all for your feedback.

I said TRY not to, I personally use my phone all day and my battery only gets down to about 75% -85% at the end of the day, so it takes nothing special for our phones, unless you do heavy gaming or movie watching all the time.
And what I said, which wasn't throwing rocks at you, is that you probably just reset your fuel gauge as there was a lack of power to the memory chip, and like I said in my first post, Search EXTWEAKS and Siyah kernel as they have that exact function in them which does not require you to drain your battery below critical values or at all.

hello again, just posting screenies that i promised

(its in croatian,but you can see what is important)
So as i said before. This is roughly really 50% MORE then what i was getting first few days on ICS. now, i dont know still if this is very good or average, but
it gets me trough day for sure. As u can see, i posted "screen on" time, cuz i was not getting even half of that before and i still have 34% left!
The day was filled with 5-6 emails, i watched 4 youtube videos, did cca 29 mins on surfing and cca 30-35mins in plants vs zombies. few sms, few calls.
So, im not playin smart here or anything, i just have more batter with whatever i did, and it makes me happy
Cheers

You getting more battery after 3 days could quite simply be due to the fact that you flashed new firmware and it always takes a few days for the kernel and modem to 'settle in'. You will never get a true indication of battery drain straight after flashing firmware.
And to the guy above who said he can use his phone the whole day and it never falls below 75%, wow!
I would love to know what firmware, kernel/modem combo you're using.
