I've heard that having your screen off setting to 128mhz that it drains more battery than 284mhz and does not let the evo perform correctly. Is this true?
I have mine to 128mhz atm and dont seem to notice qany diffrence in battery loss to when it was at 284. I have only had it this way about 24 hours but so far not a big diffrence one way or the other
Haven't noticed any extra power drawn, only thing I noticed and hate is that when you wake up it can lag bad, until the profile changes to a higher clock

Im interested in this also. I saw some people say 128 drains more battery but nothing to actually show it. I am running some tests of my own currently. Im sure it will be hard to see a difference unless there is something crazy going on.
It must have been me who posted about the 128Mhz bug first.
I'm running latest ota stock rooted, latest ota radio/wimax with Netarchy's 3.0 or 3.7.3c kernel.
I noticed that when I had 128-998 set on boot, the phone wouldn't sleep properly, and the battery drain in standby mode was ~3x what it normally was.
The normal battery drain for my configuration is about 1% an hour in standby.
If you are running a different rom/kernel, I suppose, it's entirely possible not to see this problem. Test it yourself and find out.
I have had my Evo clocked at 128 for Min and Max for about a day. I initially thought the reports of uneven performance were wrong, but a few runs of Pandora during "Screen Off" did cause some long pauses and some FCs on a couple of occasions. I suspect this is why many recommend increasing the clock to 245, especially when you have process heavy apps running.
I personally don't think the difference in such low clocks will have a significant impact on battery life, but for those of you who get the warm and fuzzies from the absolute lowest setting, I have been playing with my Min @ 128 and Max increased to 245 for a couple of hours. It's jumping out of the low clock much smoother (I can immediately drag the lock bar down) and I haven't gotten any FCs while using Pandora with the screen off. I have ran Pandora with the Screen Off and the "adb shell powertop -d" from my terminal. It is reporting that my Evo is staying in the 128 clock, but, like I said, it's transitioning to higher clocks without a hitch when I turn it on.
Hope that helps.
I've also found that 128 is just too low for things to work properly. It stutters a lot when the screen comes on and things like music also stutter.
Having tested this for a little over 24 hours in response to the increased battery drain, I could not tell any additional battery drain still after 24 hours. On the flip side i could not tell of any additional battery saving either. At the end of the day i was in my normal range.
I do not use the Stock rom but do use Netarchy's latest kernel. So ti may just be a stock rom thing. I will agree that the screen comes on sluggishly and music will skip if you have it playing with the screen off. Since i was unable to tell any significant benefit from lowering it i will be stick to 284.
I prefer screen off profile to scale down to 285mhz as opposed to 128mhz. I know the clock differences are minute, but the phone feels more responsive and ready for action when woken up at 285mhz. You can feel the 128mhz drag.
Due to some of the instability I've gotten, I've decided to bump up the Min to 245. It runs much smoother and I cannot see a difference in battery life. I think the occasional lag and FCs that 128 might cause will hurt your battery life before the increase in clock will. I'm now with the "128 is not an option" camp.

What is your screen off profile, min/max? Obviously 285 is min, but what is your max? What about when the screen is on?
I have my screen off setting for 245 min & max. I get no stuttering pandora and it doesn't **** itself when I turn the screen on. The transition to normal is smooth.
I am getting over 40 hours on battery....
with the set-up in my signature below.......
I have Set CPU set to 245/128 with screen off. I get almost no drain with phone resting. Went to be last night and when I picked up my phone this AM, it was still on the same %. This has been consistent for the last 3 nights.
If you go to the baked snack rom thread, towards the last two pages as of today....I discuss my set up. Others are experiencing the same kind of battery results.
I get no hiccups from resting to on. Pandora plays fine. If it needs the 245 for Pandora or such, it's there. If not, it goes down to 125 and uses almost no battery over an extended period of time.
I just tried setting 128 as min and 245 as max for screen off and my phone got stuck in a boot loop. After sitting idle for a few minutes it started rebooting on its own.
I had to remove the battery and was then able to get into the OS. I have since set my phone back to 245 . I will update if I find out this was happening for another reason or if I try 120 again.
My phone is really starting to piss me off. I've had this thing for a damn month now and I've had one goal-to achieve battery life to get me through a typical day and have a solid working device that I can depend on.
Do I have that? Hell no.
I'm getting force closes on Gmail, com.htc.bgp is sucking resources according to the Watchdog giving me alerts constantly about it.
According to Current Widget my screen off mA is about 80-100 which I know is ridiculously high. When the screen is on it's close to 440-500 mA.
I have netarchy 4.2 cfs-bfq-more-smartass and according to the kernel testing webpage, those numbers are way too high for this kernel. I'm on Myn's RLS 3 also.
I have the newest Lowrider theme flashed.
Mobile data is not set to be always on.
Background data is off.
I don't know what could possibly be wrong? A rogue app? Something is just not right here.
PS-I'm rooted with Unrevoked and have Clockwork MOD recovery.

Well what do you want your Up Time/ Awake Time to be like?

Well, right now my up time is 7 hours 44 minutes and the awake time is 1 hour 42 minutes. I have 29% battery remaining and phone has only been off the charger from a full 100% charge for about 8 hours.
I would like to have between 15-20 hours of Up Time and about 5-6 hours of awake time.

ahhhhh aiight. hmm...
Try switching your governor to conservative in setcpu. but for screen off, make your max the option right above 245 (i cant remember that number..i think its 384?) and the min 128 and set that governor at smartass.
For your advanced options, keep the top box at default and make the next boxes this:
95
45
0
15
How do you charge your phone? USB or wall adapter?
Okay I'll try that but I don't think that it's SetCpu...because I uninstalled it and everything was still funky even after a reboot. This is really pissing me off.
Well I'm not saying setCPU is the problem because it hardly ever is. But with the conservative governor, things should be a lot better based on how it deals with the underclocking.

Yeah but I still have the issue of having high power draw when the screen is off. I just don't think that the CPU is sleeping right or the phone itself. I just want to figure out what is wrong here. Could the theme maybe be the reason? I don't see any reason as Watchdog isn't reporting any apps to be high CPU consuming.
Does Lookout Mobile Security tax your battery?
EDIT: I always use a wall charger, the stock one that came with the phone.

You're not the only one. I'm right there with you, bro. I went from Fresh to Azrael, and I've got the same battery suckage. I blamed Lowrider, too, but that's not it.
I noticed at one time today that I spent 39% of my time searching for the Sprint network, which I know is complete crap.
I keep 4G turned off at the office, where my signal isn't great, but I know it's better than 39%.
Some app is eating my battery, and it's gotten worse since I flashed the latest ROMS.
I'd try looking at your logcat to see if there is any unusual errors. It might bring out what is wrong.
However, I have to ask, have you tried the battery fix? I'm getting around 24 hours with moderate use, my average screen off mA is about 90.
What exactly is the battery fix? Just calibrating the battery?
Get this ****, now my computer isn't recognizing my phone. It's saying "USB device not recognized"
Have you tried wiping your cache and dalvik? It sounds like that or possibly your system files have been corrupted. If wiping doesn't work I would try flashing another copy of your ROM.
Maybe you have a faulty battery. Maybe it's the kernel not placing nicely with the battery. Anyways, you can't really get mad at the phone when you're running homebrewed/dev custom roms and kernels that don't come standard on the device. Have you tried running it stock and seeing if you still get the same results?
With the USB disconnection, have you tried these solutions from here

Yeah, pretty much thats the battery fix. Its listed on the homepage of the Kernel Benchmarking site, among several other useful things.

Man, those settings are strait. I've tried every kernel under the sun, Myn's rom with netarchy's Nohavs, and Collins battery tweak, which I installed correctly and took, nothing worked. I had even used setcpu, and it didn't work. I then applied these setting and my battery life has tripled. Thanks!

screen off ma doesn't seem ridiculously high.
in my readings and experience (i am maintaining 6 evos between family and friends! ), poor battery life has usually been a result of leaving mobile data always on, a "rogue" app, bad rom flash and/or a kernel that doesn't play well with the phone. rogue app and kernels are usually the culprit though.
have you tried flashing a rom and not install any apps? that would help you determine if it was a rogue app.
to determine if it's the kernel, try a safe kernel like htc #17 which also idles great. the newer kernels are much more "selective" on which phone it will run properly on.
(i find your sig ironic)
Droid incredible. Rooted, virtually every rom through rom manager causes my phone to battery to drain very fast.
After a charge itll drop to 90% in about twenty minutes. Iv heard thats a droid thing.
From that point, it steadies but still is losing juice FAST. Phone has been awake for 8hrs today with light usage and is currently at 70%. Gps off, wifi off, etc. No vibrating feedback, auto brightness.....all settings geared for battery conservation.
Im using Incrom 1.6 with a stock kernal. Any ideas or thoughts are appreciated as i dont stop hearing that everyone in the world is rooted and enjoying their batterys new ability. Ohhh, btw extended battery, red htc one in case that matters.

Try flashing some new kernels..try a couple out. If that doesn't work did you over charge your phone? Or use a car charger?
sent from my Dinc
Its not the battery cause when i revert to stock the battery is normal for what im used to. The change is noticable wen i use any of the custom roms.
Right now wrkng on flash radio, hit a bump waiting for email back.
Ne other suggestions from u or nebody wud be apreciatd
I use the app batterycalibration after flashing new roms it works well for me

Everybody's definition of "light usage" is different. Losing 20% in 8 hours doesn't seem that bad to me unless you litterally never turned your screen on. That said, here are some things you can try:
1. I've found that the auto brightness sucks and I'm better off just manually setting it to 25% or so. That's fine for indoor use and you can't see the screen in bright sunlight anyway regardless of the setting so why bother burning battery trying?
2. Try flashing a kernel that allows you to underclock and undervolt. Perhaps one of Ziggy's nonHAVs kernels (I have found that HAVS kernels to be unstable, but YMMV). Either use the smartass governor or setCPU to cap screen off at 384 MHz.
3. Carry a charger with you
I'd see what is using your battery in settings.
Also, you could try chad's sense (12/28 I think) incredikernel, which sets the max clock speed really low when the screen's off (defaults to smartass governer).
If you wanted to try CM7, gingerbread has a much better battery usage UI that'll give you a nice graph of battery usage vs. time for phone awake time, signal strength, wifi and some other stats.
Hi, I was wondering if it's typical for the Evo's battery to take a rather large dip upon unlocking it after not using it for awhile but keeping it on. Around 15% under within the few minutes that I used it after waking it up from maybe about 4 hours or so of not using it and just keeping it locked without any phone calls or other disruptions.
Why does it seem to want to ramp up something like crazy when turning the phone on after not using it for awhile? Or does it actually need to do that to function? Thinking about trying out the conservative governor and jacking up the minimum MHz so the performance isn't horrid.
Using CM7.0.3.1 with SZen, have tried the SZ, smartass, and InteractiveX (current) governors.
Radios and what not are all up to date.
Trying other governors doesn't seem to help this issue at all (if it is an issue).
tried a reflash? I think i had some battery issues the first time i installed CM7. I currently use SZ 2.1 i think with SBC and BFS. My governer profile is set on savagezen and I get pretty good battery life. My phone never has huge battery drops unless I'm using the ever living crap out of it.
Nah, I had a 100% clean flash two times over, I reflashed last time for a different problem which was fixed because i was messing around with settings, not from the system/kernel. I mean I could reflash it again but I've had tons of clean flashes and always have noticed the issue, now that mostly everything else is fixed for me I'm getting around to this issue to see if it even is one.
Same problem drops 5% with in 2 minutes, I've calibrated tried cm7, miui, and stock they all do it...even bought a new battery...

Mine doesn't necessarily drop a certain % in a certain way/timeframe, just a large dip after not using it for awhile. As if it's taking an enormous amount of resources to try and wake itself back up and stay awake after being asleep for so long.

I switched to a SBC kernel and fixed this issue. used to drop from 100 to roughly 85 % in as little as 10 min off the charger
did you re-calibrate you battery stats???
This is w an extended battery and an amount of usage today...its all about finding the right combo.
I reset battery stats every new kernel/ROM I change. Is it useful for any reason to reset after switching governors? I'm going to try Tiamat next probably.

I use SZ as well, doesn't help it.
Or rather, there's no immediate drop like i said for me. Just quickly depletes after a long wait.

What do you use out of curiosity? I'd love for mine to have a steady drop like that instead of a massive dip, 8hrs on a very decent amount of use too. Even with the extended battery that seems like so much. Unless the extended is literally double the life?
Yesterday I flashed Franco's Kernel along with his app. I am running CodenameAndroid 1.6 ROM with Franco's Kernel r135 nightly.
I haven not been getting the exceptional battery life that everyone has been raving about. I understand every phone is different, and there are tons of contributing factors to battery life.
I have my screen brightness very low, location services are off, no LTE running (I'm running on 3G), however I've had wifi on all day today since I am at home. I've undervolted by using Franco's paid app and am running On Demand governor. However, I have generic hotplug turned on because I'm not always on my phone and messing with it. It's 1 o clock, and I took the phone off the charger at 8 this morning. I'm already down to 79% and my on-screen time is only 18 minutes while my idle time is 3 hours and 44 minutes. Other than that, I don't have any apps unning in the background accept for the regular things that should be running.
To the point, am I doing something wrong? It just seems weird to have that much battery drain and have my phone on idle for almost 4 hours and on-screen time to only be 18 minutes. Are my expectations too high for this kernel? I've heard awesome stats as far as battery life goes while using this kernel but I'm not seeing it. Is it because the kernel hasn't fully "baked" into the phone like some people say? I appreciate the feedback.
That doesn't sound right. Do you have BetterBatteryStats installed? That way you can find out what is keeping your phone awake whilst your screen is on.
Also, what are the rest of your kernel settings? Mine:
r135-512
384/1228
interactive (no hotplug works best for me)
I don't uv, but let SmartReflex do it's job for me.
This works best for me with BAMF (atm, but switch beween that rom and Liquid quite often). BAMF gives me best screen on time, but idles less good than Liquid, which gives me less screen on time. On a day of heavy usage, BAMF wins.
What I'm trying to say is, find your zen in rom/ kernel/ radio combo, because you might just use your phone differently then me (and others).
Oh, and I use the Samsung oem 2000mah battery. That helps too. I'm getting ~10h of use with ~4h screen on on a charge.
Hope this get's you on your way mate
