What is the thinking on which of these is the best way to increase battery life? I'm rooted, stock ROM and kernel, to the extent it matters.

For those of you using Tasker to manage battery life, how do you have it set up? Looks like this is the best resource I've seen re SetCPU settings, but I'd welcome any other input people may have...

Thanks!
 
First of all no single thing controls it as its collection of policies which dictates the overall power consumption taking in you have decent efficient radio also. But SetCPU is a must if your rom does not have mCPU performance frequency handling. As you want to setup advance mCPU policies defining the clock frequency when screen is off to the lowest and when its on and if nothing requires resource its then its underclocked. Not taking in your kernel supports OC and has types of pre defined governors as voltage swing can even make it unstable even stall and freeze the device.

The biggest thing to kill battery is the screen so what you might want to have the blacklight intensity low. Far as the connection goes to push out data you can use JD and based on given interval sync data and have connection(wifi+data) disabled when not used which will save more power. Far as memory/resource goes you can also disable services that you never use and set up policies to keep it disabled on boot and could manually be started by user.

Keep in mind I am using standard stock battery as Mugen Power 1650mAh is out of stock :p but my battery is calibrated. As you can see its collection of things which controls it and not single app or setting.

That actually dovetails with a related question I had -- I'm running SetCPU, using the profile I linked in the original message. Having done that, is there any benefit to using another service as well, like JuiceDefender or Tasker, or would that result in apps running but basically just duplicating effort (or worse)?

Well I myself don't use JD but that up to you as you can only tell based on your setup which will require access to data sync. I mean if you have alot of data intensive widgets and apps running then you can install JD and setup duration for sync interval.

Current profile:
mCPU scale: Max:1017mhz/Min:368mhz (ondemand)
Charging: Max:1113mhz/Min:768mhz (smartass)
Screen Off: Max:245mhz/Min:245mhz (powersaver)
Battery < 5%: Max:368mhz/Min:245mhz (conservative)
Battery < 30%: Max:768mhz/Min:368mhz (ondemand)

WHat in the world? 2 days and your phone isn't even at halfway battery? What Rom + kernel and other combination are you using? The most I have ever gone without charging is 15 hours.

Don't be fooled as I downloaded NB#7 to flash over NB#6 connecting via USB it was reset or as you can guess it would be higher. Now my signature explains what I am using but you won't see it with forum app. So far with stock battery I did good wait till you see when I get extra juice with Mugen Power 1650mAh :p and I am not even talking extended pack just the stock size.

^you must never use your phone. How much talk time per day do you use? I talk on my phone probably 3 hours every day. No way your even using your phone with that kind of battery life.

You are simply under clocking your phone to 245mhz and never using it, of course you get tremendous batter life.

I'd like my phone to last until 6 at night and not lose 10% battery life within 5 minutes of unplugging it. :/

You realize this applies for everything right? Or are you saying because you drive your car you couldn't drive my car? Its clear you haven't even read the thread as OP was asking for opinion regarding how to maximize the resource efficiently same time keeping power consumption minimal. Only OP will know and find it useful if he decide to apply it as that goes for everyone else, I been doing this for "long" time.

Okay so, your Prius gas mileage should apply to my truck? Oh wait. Thats right, it is different.

Appreciate all the screenshots you threw up everywhere, but because you do not have a EVO the battery life comparisions are completely meaningless, because everyone else in this thread has an EVO, so seeing that you get a 2 days on a charge has absolutely no reference point or meaning to anybody else.

It confuses people, like SMALBA who couldn't understand how your battery lasted so long with your usage compared to his EVO...

Tips on software optimization is fine, battery life screenshots that has nothing to to with an EVO are pointless and confuse readers who think (rightly so) that they are talking to other EVO owner.

I been doing this for "long" time.
Run "along" now.

Well if you want to roll that way sure lets rip apart your pathetic attempt after humiliation with limited knowledge.

^you must never use your phone.

Guess someone can't read basic graph? Those swings didn't happen via magic as those does shows usage. Now if you think it was done via idle well then it says more about your knowledge you learned in grade school than actual fact which everyone can see for themselves but you.

How much talk time per day do you use? I talk on my phone probably 3 hours every day.
Really?

Once again that says more about you than actual info posted. Because if you think so with your limited knowledge it does not change the facts. Which is clear as you have no idea how SoC much less kernel or voltage swing/sag works much less actual uft.

"You are simply under clocking your phone to 245mhz and never using it, of course you get tremendous batter life."
I mean really? This is what happens when you don't read things in first place let alone comprehend it as outlined before you were even born in this thread.

Thank you for not understanding basic there einstein.


Appreciate all the screenshots you threw up everywhere, but because you do not have a EVO
You are correct but I owned Leo1024 in 2009 where you own Evo(Leo512/Leo1024 mockup) in 2011. Which alone by itself another thread as your "same" hardware is what we had 2years ago lol hell with even lower battery power as it was 1230mAh.

the battery life comparisions are completely meaningless
I mean really guy? As you have 100mAh more on Evo than my stock battery. This alone don't need defending. But if you think even if my was higher even then it didn't translate in to nearest hour when you round it up.

because everyone else in this thread has an EVO, so seeing that you get a 2 days on a charge has absolutely no reference point or meaning to anybody else.
Really guy? You think this is Evo section? Really? What gave it away? SMH someone should learn basic and apply it as we been doing this for years, if you can't grasp that idea well that sounds like personal problem.

It confuses people, like SMALBA who couldn't understand how your battery lasted so long with your usage compared to his EVO...
You should worry about yourself and not him as if he asks ill tell him howto which he can then amend to his own device and see results, which you clearly fail to see nor know how to do. As if you did we wouldn't be having this silly convo now.

Tips on software optimization is fine, battery life screenshots that has nothing to to with an EVO are pointless and confuse readers who think (rightly so) that they are talking to other EVO owner.


Run "along" now.
At this point its just random ranting in your end as it has no actual meaning.


BTW thank you for sharing your 1year iphone run away knowledge with us. As the pathetic babble alone speak for itself without any applicable facts. When you have basic comprehension in electronics then speak here much less recommend anyone anything. Only fool would think when it comes to actual numbers it differentiates when device has higher mAh compared to the test device with lower and then if not rounded to nearest hour.

Also anyone who is serious disregard the babble as he has no idea how to achive this superior efficiency so he is mad. lol I mean last time I checked it was me who was posting stuff on XDA and other dev sites. Where were you posting your stuff? Thats right let us dev's do our work as you sit there and watch and try to grasp things beyond and way over your head. I mean this whole thing could have been avoid with just simple reading and basic comprehension.

Wow, I worked really hard on the reply, all of 5 minutes, only to see he got banned, lol. So I deleted the whole reply and replaced it with this:

He was on this forum for only about 30 days, yet had almost 500 posts, perhaps if he checked the thread location before replying, he wouldn't have been banned.

I'm sure the rest of us will be happier without his "input".

I think a combination of setCPU with something like Tasker or JD is probably the best bet. Personally, I only use setCPU because I consider my battery life "good enough."

Back when I first rooted my phone, every second gained was important. These days, I charge nightly out of habit, even if I don't need to.

Here's something not many people know: If you trickle charge your phone (via a USB port, not on the wall a/c), you will get much better battery life, all other things being equal. So if you charge overnight, do it via a USB port on a computer, rather than a wall a/c charger.

Actually unlike you I noticed him around the forum helping people. His post was actually more informative than your ranting as failed to even make your case other than just go on and on about anything not even anyways related to this subject. Has your input actually contributed to anything?
HKM, is that you?

I just though it was a touch silly to compare the battery life of another phone model on a different network to an EVO. A different phone's battery life, and graphs showing time between charges has zero relevance to an EVO owner.

Lets be done with the ranting. The guy got banned, that should say something.

To the OP, I use SetCPU, I cannot make a direct comment as to it being the best, as I have not used every option in your poll.

Can mods check IP's to see if the two users HKM and AltM2 are the same?
Yes they were indeed duplicate accounts - as well as Hypernode. We discovered it earlier in the day and were deciding what to do. All accounts have been banned. Now, lets please continue on with a civil discussion.

I'd really like to hear some input on the best way to have the EVO setup for the best balance of performance and battery life.

I'm using SetCPU, but would change if I saw a better alternative. I set my to 'screen off' on powersave at 128mhz, but that lead to missing phone calls because the phone wasnt fast enough to react, lol.

That's too low. 245mhz is probably as low as you should go.

I use Mobile Guard. It actually works. I have seen an improvement. I use my EVO a lot during the day. Heavy texting, email use, internet, some calls....and usually I have to charge my phone at least twice a day. With the app, I let it charge once overnight and didn't have to charge at all again until around 9pm.

It's difficult to find the app by searching mobile guard, so I just searched battery booster and it came up.
