Does setpcu really work? With making battery better. I have it set with profiles just not sure if its really helping or making it worse.

I dont think it is really needed with the CPU settings in CM7 now. Does the same thing for the most part im guessing?
you can do baisic clock scaling from within cm7 settings. as for profiles, if you have a custom kernel and run smartass (on tiamat) or savagedzen (on savaged-zen) governers, you shouldn't need it. those governers do basically the same thing, just smarter.
I was wondering the same thing. On sense roms with setcpu I could easily go a whole day and still have 50% battery left. With cm7 I can only go about 14 hours before its completely dead. The odd thing, I have a profile in setcpu to lower the speed to 245 (the min) below 50%. On sense, I can totally notice it slow down, and can totally notice the battery draining much slower below 50. With cm7, I don't notice any slow down and the battery will actually drop quicker below 50, much quicker than if the battery is above 50. I am using whatever kernal cm7 came with

Try using Tiamat or SavagedZen. I get great battery life on both. You would definitely benefit more from an SBC kernel, but you will still get better battery life with the non-sbc builds of those kernels as well. Which you choose is up to you. Despite a bad name, most users have no problem with SBC kernels. However, the risk is still there. I'll take my battery possibly pooping out early for the extra hours I get out of SBC.
Once you've flashed whatever kernel you want to use, set the governor to smartass (or SavagedZen, if that's what you're using).
I searched for this and found a couple results but I'd like a fresh thread with only helpful information. Exactly as the title says: What are you guys doing that has given the best battery life without sacrificing much speed? Post your method, your ROM, your Kernel, and your battery life in hours between taking it off the charger and to almost dead. Thanks. This will help everyone I hope.
I'm running synergy rls1 underclocked to 652 and down to 225 when screen is off......I've gotten 3.5 days battery with 50 to 75 texts/day and a few minutes of calls with light internet browsing and still had 22 percent remaining. The only thing that i notice lagwise is home screen redraws take a lil longer than normal. I've read the v6 supercharger script fixes this issue but haven't gotten around to trying it yet. Before that i was running cm7 with tiamat 3.3.7. Battery life was awesome with that setup, could go four days but it was really annoying that i could never get my GPS to work no matter how many fixes i tried. By the way my mobile network was turned off the whole time except when doing my light internet browsing. All the animations turned off as well, with the screen set to the lowest setting i can tolerate.

I've been running Myns Warm 2.2 Rls5 with netarchys sbc build and going on 2.5 days of battery life with heavy use before I have to plug it in (extended battery btw). More or less 110-150 sms per day, listening to music at work, reading on xda, and two or three 5 min phone calls. No settings have been changed except for screen time out from 1 min to 30 sec. With light use I get about 4 days.

vipermod
Try vipermod, it's a script you can use on Terminal Emulator to undervolt your kernel. I undervolt mine -50V and the battery life is great!
Isn't vipermod only for AOSP kernels?

Hi everyone,
This is my first post.
I have thoroughly searched forums, trying to find this information but I'm having a really hard time finding any coherent answers, and even harder time finding any actual statistics.
Initially when I got my evo4g recently, used, it's cellular standby was taking up 45% of the battery. I got juice defender ultimate, and downgraded to 1.77 from 2.15 for the PRL and NV, which dropped that 45% down to 4-10%.
I've tried both cyanogen, and synergy roms. The interface for either is both good, so it's a wash to me. I underclocked both to 128mhz idle and 768mhz regular. I also disabled
On Cyanogen I tried savaged zen kernel, and stock kernel. I have not tried tiamat. On Synergy I tried golden monkey, and aggressive freedom .9. I use smartass governor.
On synergy, I used setCPU to create a profile to on screen off, to set clock speed 128 to 384, with ondemand as the governor, while using smartass as my regular governor, with 128-768 as my stock speeds.
When I tried the savaged zen kernel, the vipermod was only able to undervolt .25mv. Any greater and it locked up. .50mv would work for a while, but then just randomly crash. I don't know the undervolt rating of golden monkey, but it is not flexible. Aggressive freedom is pretty heavily undervolted.
I'm making the assumption that my device doesn't like HAVS, given that, or savaged zen is pretty aggressive in the first place. I'm unsure.
I disabled rotation, screen brightness is set to minimum, and am still not getting acceptable battery. I'm a fairly heavy user. Currently, it says 64% of my power is my display, even though it's at minimum.
I'm still tethered to keeping a charger with me, which really sucks given that the 12v adapter in my car is dead, and I drive a lot.
Often when I'm using my device, I can drop from 45% charge to 15% charge in an hour. It's a fairly new replacement battery. I read 4200mv in rom on it. I've tried resetting my battery stats.
I don't really know what to do. As of currently, the only thing that drains more
than 10% is the display. When the display is off, and I don't touch the phone, it drains incredibly slowly. I've dropped from 100% to 58% in the last 4 hours with intermittent use, haven't made a single call, and have sent a total of 3 text messages. I've lost a full 15% of my battery watching 5 3 minute youtube videos before.
Would cyanogen, or synergy be recommended for max battery life, and given cyanogen or synergy, which kernel would be optimal for battery life, and is there anything I can do to make my minimum brightness display use less power, short of not being able to see at all?
People get best batt with aosp so they say.

What kind of replacement battery, and where did you buy it?
It is possible to buy a "brand new" battery that's been sitting on the shelf long enough to not be very good. I would guess there are also counterfeit batteries out there (although I do not know this for a fact). A poor quality or old battery might be causing this?
Actual HTC branded battery from sprint. I didn't have to pay for it. I still am trying to figure out why my display says it's taking up two thirds roughly on minimum brightness. I currently am on synergy with juice defender set to aggressive, with min brightness, and freedom v. 9 aggressive.
Would Cyanogen with Savaged Zen or Tiamat use less?
I may have to end up buying a bigger battery? It's often dead 10 hours after I take it off the charger.
I know nv and pri 1.90 have problems. How is 2.15? I currently have 1.77.
Sorry if I talk on circles.
Also, are the v6 supercharger script, and it's associated scripts worth looking into?
I personally think juice defender is just another parasite. You should turn on/off your radios when in/not use manually. The smartass governor is used basically has a built in screen off profile making juice defender or setcpu irrelevant. the 2.15 PRI is nice, I'm using ti with no problems.
I average 2 days on stock battery:
CM7
Tiamat 4.1 > smartassv2 governor
Vipermod: -100mv , 825mv floor
And aosp will always have better battery life than sense.
Right now my display is at 42% for 11 hrs and I'm on the latest radio pri nvm and prl and don't have any crazy batt drain. And iv heard decks Rom is bad ass idk guess it is what you prefer. As far as v6 you will hear and read mixed results I use it on setting 7 just cause it kills apps that won't kill forever or don't exit right
Ps +1 to juice defender never helped me and i now use system turner instead of set CPU cause it can create a script for CPU usage unlike set CPU.

I'll just piggy back off this thread. I'm need some other suggests or help. My battery is draining unusually fast lately.
This was thirty minutes of use. I was listening to Sirius NFL radio through Dolphin HD. The battery was at 90% when I disconnected it from the charger

This is twelve minutes after I stopped listening to Sirius.
I had my brightness settings to lowest possible. I work at night, so I don't need very bright.
I'm running CM7 Nightlies; currently on 11-10-11 (#250) with CM7's kernal. Set Governoer to Performance, CPU set to 245 min, 1113 max. I have the seidico 3500mha battery. I find these work well for all the video media I consume at work--Netlfix, NFL Game Pass mobile, Plex, Hulu, Sprint TV, and so on with HDMwIn. I also do some gaming with SNESoid with Sixaxias Control or Wiimote Controller. When at work, the phone is on a charger all but about thirty minutes.
I was using Tiamat 4.1 and wasn't having nearly as rapid battery drain with the same settings. I went back to the stock CM7 kernal, because Tiamat caused flash player not to work properly in either Browswer or Dolphin HD.
I've tried wiping the battery stats and draining the battery completely after flashing the updated CM7 nightlies. I just having done data wipe at this point. I haven't tried using the original 1500mha battery either. I akso turned off the back up data to google servers. The only things I have are 3g/2g raido, All other radios are off unless needed. No vibration is off except the one on boot. I do have auto sync on. I also use WP clock live wallpaper. I have all animations off.
I don't expect my battery to last to the day or days. I use to get a good eight to twelve hours with normal use--email, IM, web, phone, and light media consumption.
Any ideas?

That sucks your getting such terrible battery life man :/ I'm running synergy with stock kernal and 2.15 pri, and I get about 23-24 hours on my 1500mah battery, and that's with everything turned on no juice defender or anything, but I also charge my batteries with an external charger, Idk if that changes anything or not...
I keep WiFi on almost 100% of the time too...

I installed Amon Ra's flasher instead of clockwork, then went into recovery, wiped everything 3 times over, including battery stats and dalvik cache, installed cyanogen mod, installed savaged zen kernel, installed gapps, did first bootup, and have since had better battery life, atleast for the last few hours. I've been on wifi the whole time though.
I can only undervolt 25mv on Savaged Zen, any more and it locks up. However, on the freedom kernel for sense, I used the aggressive setting, with SVS, instead of HAVS. Is tiamat SVS? If so, would I be better with a manually undervolted tiamat, instead of savaged zen?
I've read some things about evo deck having better battery life than cyanogenmod. However, I don't know which version of CM7 they based it off of, CM7, or CM7.1, and I also don't know if these claims are actually true. Can anyone confirm this?
Why is juice defender a parasite? CPU cycles? The "3%" it uses, is much less than the 35% cellular standby that I've been seeing, due to piss poor signal.

+10 to the Arrow Thread ^_^
So the consensus is that evo deck is thebest battery rom ? Then which kernel? Savaged Zen or tiamat? Given that savages Zen freezes at 50mv undervolt and I was able to run freedom aggressive, I'm not sure. Is havs worth it? Or do I go with tiamat. If tiamat, do I go with newest?

they both are the newest and are both HAVS, if you look at the thread in my sig. the only thing is that tiamat is going to have future updates while SVZ will not. and i'm undervolting my SVZ kernel to -75mv. you probably couldn't because every phone is different so you phone probably cant do more than -50mv. none the less check the thread in my sig to learn more about kernels and roms that are aosp. ^_^
I've read that thread already. I found it odd you suggested the godmode kernel even though its not a gingerbread kernel.

the one in the attachments that you can dl is a aosp version he toast made for gingerbread roms... or you can just go to his thread through my thread, the link is under the GoDm0de description...
Magically, my phone stopped rapidly draining out overnight. Maybe it's because I wiped battery stats?
With evo deck and savaged zen at -25mv, I got 24 hours of battery before I hit 80%, but that was with next to zero use. I then used 3g for a half hour, gps for 15 minutes, and made 4 seperate under 10 minute phone calls, which drained the battery down to 15%.
The battery use section says 49% is cellular standby. This is with manually turning on or off radios. Display is such a low %, it's not even showing up.
Do you have bad phone reception where you are at ? Cause isn't that cellular stand by? When the phone is searching for service ?

I always have poor service lately. If it wasn't for a friend working for sprint getting me a crazy discount, I'd have switched carriers a long time ago.
Only wipe battery stats when your battery is fully charged and shows 4200mV in battery monitor widget. Then you need to run the battery dead, then recharge fully to calibrate it.
Next, no ROM or kernel will fully charge ANY extended battery unless it uses SBC. This is fact, I have tested everything available today from asop to sense.
You are fighting a battle you cant win. Turn off automatic sync, set your wifi sleep to never while uplugged, and uncheck the always on mobile data.
Good luck, there is no solution, phone is what it is.

I have the savaged zen kernel with SBC turned on.
I have noticed some instability in the phone ever since I undervolted 25MV. It locks up for moments at a time, which is aggrevating because it makes me miss calls. It unlocks intermittently. It crashes at -50mv, so maybe I simply can not undervolt at all. Atleast I have HAVS, which is better than stock kernel.
I tried the v6 supercharger, 3g turbocharger, and kickass kernelizer scripts (at the same time), and the phone became horrifically unstable, so that is not a route I'd like to try again. For v6, I used 512 balanced, 3g I tried fastest, and kickass doesn't have settings. I'm not sure if those affect battery at all, but I wasn't happy.
I've read this thing about turning off atime to help flash disk IO performance by a rather significant margin, reducing battery strain a smidgeon by finishing tasks faster, and powering down the flash memory faster, which I would like to do (which works great on linux computers, which is another hobby of mine), but I'm not really sure how to go about it on android.
I noticed synergy rom uses the fun optimization of using EXT2 to boost performance. Any way to easily implement that to an already existing rom?
I am using one of those ANKER 1700 MAH batteries.. I am also running LINOFISH 1.6 sotkc voltage and MIKG ROM 3.11. I just switched to INTELLIDEMAND GOVERNOR. I am wondering if anyone uses that and if being at 78% battery after 8 hours is good?? not too much use of the phone...
Is there a better governor to use to get better battery life but no lag? intellidemand seems to have a small lag opening apps..
Thanks..
I'd use underworld with SBC. It will help u get the most out of an extended battery. Been thinkin about getting one these myself.
Those batteries r great. I'm using one as well. Id recommend smartass gov and the underworld SBC kernel

I'm using a 2000mah batter picked up on Amazon. Pretty good and it lasts about 4 hours on constant use, including putting my phone to sleeping and waking it up a lot.
Any suggestions on which governor to use? Using Tiamat 4.1 SBC (not even sure if a new one is out). Running cm7.2 also.

4 hours???? not a good battery... I have a couple of 2000MAH batteries and they stink.. the ANKER 1700MAH with LIONFISH KERNEL and INTERACTIVE X last me close to 20 hours and I still have more then 20% battery left...
I havent run mikg in a while...but I am currently on Jamieg71 KWIQ rom with mason G .15 sbc kernel running stock frequencies wheatley governor and my battery lasts at least 16 hrs (with about 30-40% remaining) phone is very responsive too. my normal usage is GPS+track my run (30 minutes most days), pocket casts driving to work, few games of DRISK, many texts, emails and calls.
Edit:..stock battery
