SetCPU

Hi all,
I've set some profiles in SetCPU but haven't noticed too much in battery life savings. I was wondering what others who are using CM 6.1 have been doing/would recommend. Should I get rid of the profiles and just have it set to on demand? Do I really need it at all with CM?
Many thanks!

How high are you overclocking?
What's your usage?
What's are your profiles?

Overclocking to 1401 on demand
I use power amp with scrobbing to last fm for probably an hour or two when not charging, while playing games that aren't to elaborate (boring stuff like sudoko) during my commute to/from work, which is probably my heaviest usage. I also do the same music set up while at work but I'm plugged in most of the time for that and volume is way down. Calls range from 30 min to an hour a day. Some intermittent web and video streaming while at home and on wifi. Typically only on wifi when at home, only when I need heavy data. Data sync is turned off when I'm not charging unless I want to sync.
I have profiles of 368/245 while sleeping, 75 priority; 738/245 when temp is 40.5 C, 60 Priority, 1401/245 when plugged and fully charged, 50; 368/245 when battery less than 10, 60; 806/245 when battery less than 40, 50 priority.
I'm thinking the fully charged one is probably redundant. Should I raise the priority on some of them?

I always set temp as the highest priority however i OC a lot higher then you. What oc kernel are you useing? This makes a huge difference some have a lot more steps which allow better power use. Pershoot is the most efficient imo right now.

I think I'm just using the cyogen mod kernel...but I'm new at this so I am a little clueless on that part. I did set higher priority on the temp and the screen off, got rid of the charging profile. I'm at 13% battery after about 15 hours, which isn't horrible but not the 30 hours some folks have been posting.
Sent from my HTC Vision using XDA App

had to dig back to find a good thread to post this on....
so I'm really leaning toward deciding that setcpu profiles do more harm than good in terms of battery. I had profiles set for temp, screen off, charging, battery below 30, and battery below 10. its pretty clear to me now that it wasn't helping my battery. and the only time I even had it overclocked was while charging.
next I'm going to just enable only a screen off profile, and see if having setcpu monitor for less profiles makes a difference. i'm not going to overclock at all. we'll see what happens.
btw I've had a rooted android phone since the G1 so its not like I don't have experience with setcpu. seems that setcpu affects different phones in different ways. so I'm still figuring out how it is on the G2.
anyone have any thoughts on this?

The screen off profile does not work.
Just use the phone out of the box and charge when its empty

really? I hadn't heard that. is this confirmed?
though, it never seemed to make all that much sense anyway, as I wouldn'y think there would be any reason for the cpu not to remain at a low freq with the screen off

The screen off profile works for me. I just set to "ondemand". Lately I've been using "cpu tuner" instead and have noticed better battery life then with set cpu. Plus with cpu tuner you get more profile options.

To be honest, not sure if its the case for you but profiles was the cause of my battery life drain. I took off all profiles and only kept screen off. Even since I did that I get about 24 hours + of battery.

I had a similar experience. The more profiles I had enabled, the faster my battery would drain.
I am using the same setup now and have great battery life. Even with heavy usage I can make it through the entire day without needing a charge.
Running On Demand 1209/245 and screen off 245/245.

Haha this was an old thread. I'm now on CM7 nightlies and would say that in my experience I've had the best battery life running no profiles whatsoever in setcpu. I only overclock to 1017 and it's been pretty snappy still. My experience in going higher than this on CM7 has lead to issues with wake, temperature and battery drain. I personally Have no need for more than 1017.
Sent from my HTC Vision using XDA App

agreed. this setcpu stuff did not help at my device. nor did it work reliant.
i am managing 1day with heavy use and a full weekend with moderate use without any "tuning".
that is enough for me.

I used setcpu for awhile, but I have been much happier using cpu tuner and "power control".
My battery life is increased by 12 to 24hrs. The key for me is really using power control to manage the screen brightness and under clocking rather than overclocking. The only time I found overclocking usedful was when playing fifa10.
Good luck

Yet another extended battery 2400mah

Anybody using one of these 2400mah batteries on their evo?
http://www.amazon.com/Extended-Cell-Phone-Battery-2400/dp/B0040MNJPC

not bad for the price

I just don't see why people get extended batteries when kernels now days are supporting my battery all day dragging on into the mornings.. i guess every phone reacts differently.

I've tried all the hottest kernels and battery saving tricks and still average only 8hrs under real world use
Running Evo Deck 1.2.1, display at 12%, couple widgets, data off (using wifi at home) , sync off, and all of that. Underclocked, undervolted too.
Browsing, xda app, etc results in 20% battery usage per hour. Battery consumption is zero at idle, but drops like a rock if i use the phone at all.

Maybe my batteries are shot - their health shows "good " though. I have two OEM 1500 batteries that I swap, but I did buy an HTC 2150mAh, just waiting on my battery cover to arrive before I use it.

Battery calibration is very important, don't know how I lived without it
Setting the VM heap to 48 allows the dalvik garbage collector to run less, improving battery
Chainfire 3d helps with anything graphical, makes home using lwps smoother, games run better etc, also saves battery by making all animations, graphics processing more efficient
If you use apps2sd bumping the cache makes it faster, and more efficient saving battery
Also updating to the latest radios etc, and making sure your prls and profile is up to date is essential, many aosp users, formerly including my self forget about that stuff
I've spent a huge amount of time expirementing with different setups, I think I've found my phones sweet spot
I have loads of friends with rooted evos, mine has the best battery and is typically fastest (chainfire 3d) makes everything snappier
Maybe with all of this info you can test these apps / settings and find your phones sweet spot. Good luck man

I wonder how the mfg pulled that off? My HTC 2150mAh battery is twice as thick as the 1500. I'd bet that that eBay battery will not yield the stated 2100mAh.

I'll agree with Zac here,
evo 3d with CM7 nightly, SavagedZen 2.2.1 CFS. removed all the crap i dont use or think they suck the battery down. live wallpaper etc.
InteractiveX governor, 245-1113mhz
No setCPU.
no juice defender
no taskkiller.
no 4g - no gps - no wifi
blutooth ON
3g always ON.
battery calibrated is a must
display set to manual around 33% brightness. but i change it on the fly (swipe the notif bar).
Now the results are pretty interesting here:
With the stock battery and all the above; if the reception is good, i can go for 2 days with moderate usage. yes i know i night i sleep, so it idles nicely.
If the signal is not so good, it will destroy the battery, and can't really get anything more than 13hours.
My typical use:
unplug at 10am.
use the phone normally.
plug it back in at midnight that night, and i would have between 35% or up to 67% battery left in the phone, depending on the factors mentioned.
Which to me, going all day is all i wanted before i started tweaking. Mission accomplished.
The quality of the reception is a killer, i'll tell you.

I bought a 3500mah battery from the same company, and it is trash.

are there any extended batteries that fit in an otterbox commuter case?

[TIP]Increase battery life by at least 50%

Here is a tip on how to increase battery life by at least 50%. For me, it has increased by 83%, given that my S II is relatively new (3 months old). It is an app in the market which you can get for free: JuiceDefender
MUST:
Remove any task killing apps (Advanced Task Killer) otherwise this app is useless as it needs to be on at all times.
I have my settings set to Aggressive, as I don't use my phone much during the day.
My normal on the Bombaridier v3.5 ROM by TricH was 100% at 7:00 AM and 88% at 10:23 AM with only 40 minutes of music and standby with no data connection or Wi-Fi. With JuiceDefender, I get 100% at 7:00 AM and 98% at 10:23 AM with the same circumstances of use. It is worth downloading and will extend battery life. I have 83% more battery life according to my math (which is (10/12)=(x/100)) and it is amazing.

I agree that JuiceDefender is an excellent product for extending battery life.
I have the "Ultimate" version.
JuiceDefender alongside "Battery Monitor Widget Pro" is the killer combination...
I did notice one slight bug with JuiceDefender (JD) - there's a known issue with wifi management. Phone turns itself off occasionally. The fix is to simply set JD "disabled" for WiFi management - problem then goes away.
I also listen to music (Pandora) over a Bluetooth headset (about 3 hours per day).
I regularly get about 18hrs+ (combination, on average: 3 hours on voice, lots of email). Stock, rooted ROM... bloat removed.

I agree Juice defender is purely amazing, according to JD stats, I get 1.83% more battery life, that's with aggressive settings.
Ps: Thanks for the Wifi tip

It'll be hard pressed for any app to extend my 3+ days of usage on a single charge. Just sayin..

I just bought the ultimate. I will let everyone know how it goes after a week of using it.

The first thing that came to mind is; haters gotta hate.
I use it just fine with my purposes.
Check/write emails, make calls. Nifty info widgets for updates. I just don't use it for everything because that's just silly. That's the reason why I get such a long run-time. I already have a dedicated media device, no need to watch videos, etc etc on the phone.
Just because most people don't get more than a day usage, don't mean it doesn't happen.

whoa 18+ with 3hours voice is killer.
i barely get about 16 with 2.5 voice and roughly 2.5 display on time
just fyi to those who don't know. voice weighs heaviest on battery usage, even more so than display.

I can get 2 days with moderate use but I dont realy tLk on the phone and I use wifi most of the time

Best thing you can do to to increase battery life is to disable all those Google services. I don't know why but I make it pretty clear in the settings that I do not want any auto-update or syncing of any sort but it happens anyway, so I have to manually freeze all the **** that Google insists on running 24/7.

Thanks for the tip! Extra battery life is always welcome.

Although jd isn't exactly new, but there seems to be a lot of people who just heard of it now. Not bashing but this just shows that there seems to be a lot of new android users or well xda members since the release of our awesome device. I bet most are all former ifags (don't take me seriously).

Lmao. I think this made my day. xD I was using juice defender way back when the droid eris was new and I still do! It works wonders. When I had a dell streak I went from 6-8 hrs of batt life with no usage to over 2 days.

Sorry if I sound like a tool for asking this but if you turn off the Google gmail and calender sync then how do you get your emails?
U have to manually check for mail all the time?
sorry, having issues with my battery also. I use Juice Defender but the free version - everyone that is having success with it are you using the purchase one, Juice Defender Ultimate?

Ive had my phone since october, and the battery has gotten better and better. And im not doing anything special, stock rom, no juice defender, no task killer, nothing of that sort.
I use wifi tether almost all day at work(about 6 to 8 hours) and I still have 20 to 30 percent left when i head home.

Guys please help!

Okay, I am having a very frustrating problem that I did not originally have. My phone can last me half the day!! It is very frustrating to have my phone turn off on me everyday at 5 pm ..I love this phone but this is unbearable, especially considering that this is with very, very, very minimal use. If I actually use it the phone intensely, it will drain completely in 1.5 hours. ..It was not this bad a couple of months ago.
I have bullet kernel, and stock GB rom (2.3.5)
I had it always used it on "lag free" setting OC to 1.6 but I changed it to conservative mode to try and see if that would help and it didn't. I even used the core sleeper script from the developer's section and that didn't help either. I had changed radios a number of times when I was tinkering with custom ICS roms. I got my gf this phone a few weeks ago and put the same setup on the phone and she is getting the same battery life. I bought it used.
Does anyone have any suggestions!?? ...I would really appreciate it

You can extend battery life anumber of ways.. Tell me what Is on bt by wifi sync the screen ways ths most energy so turn that down as low a you can... Sounds like you are on an old ROM ...prolly eagles blood?
I suggest digital warfare 2.7 if you are on TMobile. Great battery life. Also flash your radio before your ROM and make sure you are flashing over a clean slate.

I am running on the Stock ROM with android 2.3.5
I am running off a nandroid backup I had restored after having an ICS rom on the phone for a few days. I used darkside superwipe, then flashed radio, then restored the ROM backup.
I always keep GPS, wifi and bluetooth off when I am not using them. I keep wifi on if I know I will be home for the day so I can use that instead of 4G ...I keep my brightness on the lowest setting.
Even with the sleeper core script, turning off 1 core, its still drains out at over 7% per hour without ever even touching the phone. Something is definitely wrong because I read people on the Sleeper Core thread saying they lost 3% in about 6 hours of standby with the script running.
the battery really should be in good condition because the phone is less than 8 months old and I frequently switch between a backup battery (cheap eBay battery), so that should preserve the original a little and even w/o the 2nd battery, the battery shouldn't need replacement this soon.

Have you tried using an app like Badass Battery Monitor to check what's app or process is eating up your battery?
Also, does your spare battery die quickly as well?

No, I haven't used a 3rd party battery monitor app, I just look at the system menu section that tells me what things are using battery and it is says my screen is using 50% ...my spare battery dies very very quickly. But it always has died this quick since the day I bought it because it is a crappy Chinese battery from eBay that I bought for $4 ...the first few times I used it, it would last about half as long as my original samsung battery

You should try to forget about the extra battery... and charge your phone while off then after ten or more mins of it being fully charged unplug then wait and plug back in to charger... It will likely charge again for a minute... Do that little cycle to get a full charge. After i do that i enter CWM and reset batty stats. There is more on this if you google it.

Battery Life Discussion

Ok so here are the tools I use
An automatic radio activation tool that will turn radios/wifi /gps OFF when screen is off - Juice Defender Ultimate is my choice
A CPU management tool - I use AnTuTu CPU Master but i hear that SetCPU is also very nice
Better Battery Stats
I Have setup Juice Defender (JD) to turn off my radios/wifi/bluetooth when the screen is off, to manage auto-synch, manage screen brightness but i DO NOT use it to manage CPU. I have also not setup any special App settings in JD, it just manages power consuming hardware (other than cpu)
My CPU tool (whichever you use) is used to setup profiles based on situations. Screen off, screen on, in call, etc.
There is never any reason for your CPU to be over 700mhz unless you are interacting with your phone. When you are on the phone 920 is all you will ever need. You can set the max above 1200 if you want or need the extra power but just remember that the cpu is always going to be a battery drain.
The #1 thing to remember is that if your not using your phone actively, it should be doing as close to nothing as possible.
Now I would love to hear from others on experiences and strategies or even critiques of my method. I know many will say that JD is not needed, bit i like not having to think about it.

I stick with Trickster Mod app for CPU/kernel settings. It's amazing. Also I never use Juice defender I use Tasker :thumbup:

Good idea starting this thread but I feel that you've opened up a can of worms
I've used JD before on my Dinc2 and I liked the fact that it can manage the radios but for me, I get a lot of emails and I like something on so I stopped using it. I did try some other apps like that but JD was my favorite by far!
Check out TricksterMOD from the app store it blows setcpu out of the water! It let's you do so much more and since I've found that I can't go back to anything else.
I usually don't undervolt, I feel like the kernel developers so a good job with their frequencies so I leave that alone lol but I have been recently checking out the governor settings to try and optimize a few things, that's a tricky topic lol
Sent from my Galaxy Nexus using Tapatalk 2

Um.. wow.. i wasted money on a few other apps apparently, trickstermod looks amazing..

Not sure if this is the forum for this but a good discussion none the less.
What ROM you guys running for best battery life? I seem to get the most from aosp based roms and not cm10 or aokp ones.

Mines close to stock on purpose but I don't mind people tuning it. What did you change that helped battery? There's bit much from a kernel perspective that will really help battery.
And this topic doesn't belong in development.

i guess it belongs in general but the idea was to get all the tidbits that we need together in one app specifically for our phones. like "The CDMA Galaxy nexus Super Battery saver app that does it all without all the stuff you dont need"

Just flash lean kernel and turn off mobile data when you're not using it. No need for these crazy battery saving apps. I get ~7 - 9 hours a day, easily.

I consistently get 14 to 18 hrs. I've been using the battery for about 2 weeks now and its awesome.

Since radios are such a huge drain ...
I think my best move has been using an app called Profile. You can use it to turn off and on WIFI, Bluetooth and change the screen brightness at certain times on certain days. So at my usual time to go to work, WIFI gets shut off. At my usual time to get home, WIFI back on.
Also will change ringers, volumes and vibration on/off (always off uses battery).
24 hours no problem.
Costs a couple of bucks to get the time based control, but works for me.

Two tricks are using auto brightness and using WiFi whenever possible.
However, since I can't stand either of those options, using trickstermod to set max CPU speed while screen off, and setting color profile to morific typically helps my battery life.

CPU max is capped at 350 or 700 already there's no need to change it.

Yah why would you need to lower CPU on sleep when we have deep idle?

I use CM10 nightlies, and the latest dev snapshots of Imo's leankernel. Min frequency 230mhz, max 1350mhz, interactivex governor with his tweaks and sio i/o scheduler.
I get ~24 hours battery with decent screen-on time, from just texting, about 20 minutes on the phone, and websurfing on full wifi service wherever I go (stays connected even when sleeping, and we have cross-campus wifi here). 3g service only, no LTE here yet. Bluetooth off. NO apps--many of the market "powersaving" apps will just wake the phone from sleep and cycle a few times to write to the log file (any app that keeps track of power consumption, and half of them don't even use the system tools). GPS is on, but it's never initialized more than 1-2x a day for random needs.
Getting a lightweight kernel is a good choice for battery life saving, and getting one that actually keeps up with android mainline is pretty key.

I think it's most helpful to post your total 'screen on' time and time since charge. If someone tells me they get 14 hours, that means nothing. I can get a full day 16 hours with roughly 2 hours of screen on time, without limiting my phone via turning off mobile data, syncing, or using a juice defender app that disables a lot of things.
That, to me, is not very good at all. I saw that the Nexus 4 is getting about 4.5 hours of screen on time with a full day of being on with everything syncing, etc being on. 4.5 is actually pretty bad also compared to other devices these days.

No matter what I try I usually only get about 2.5 hours of screen on time. I under clock to a max of 750 screen off at 280 undervolted to in each setting.
I've tried many many kernels with many roms

Screen on time doesnt mean much me to me because i use my phone for personal and business use, which means I get quite a few calls.
I use the stock 4.1.1 image, rooted with SuperSu and debloated a bit. Also use Faux kernel 23m-sr and his control app.
I roughly get about 2.5 hours screen on time with light calls and about 1.5 with heavy calls - my off charger time is pretty good though as it easily gets me thru the day. I bought another OEM standard battery and just keep one fully charged at all times so I can swap. Works well for me.
I also keep 4g on - why not when you can swap batteries.

does leaving gps on all the time if you're not running any location apps bother the battery at all?

No only when you use something requiring device GPS does it turn on. Most background stuff like Google Now uses tower fix so it's OK to leave it on.

Battery life is a pretty unique experience for everyone. Apps, ROM, kernel, signal, Wi-Fi time, brightness, etc. Won't say these type of threads are totally pointless but they are pretty close to it. Always good to share pointers on how to save a few minutes of juice though. Ultimately its a big screen and turning it off now and then is the best way to save but personally I leave all my services on because that's why I bought this thing and I keep a charger everywhere I go.
