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)
I recently got into rooting and flashing at the end of last year. This site has been a great resource for how to's and learning about the ins and outs of phone hacking.
Anyways, here's the background info: rooted using Unrevoked Forever, s-off, stayed with stock ROM and kernel only using SetCPU profiles. When I was on stock software, I had unbelievable battery life. I'm a light user (~10% awake time) and rarely beat on the battery -- light calling, email, texting, Facebook, random messing around etc. Anyways, when 3.70.651.1 came out, I knew that was my chance to flash my first ROM.
I flashed SprintLovers and got decent battery life, but nothing compared to when I was running the stock ROM. I then tried almost every variation of Netarchy's non-SBC's CFS 4.3.4 kernels -- more HAVS, less and no HAVS. No dice. I've tried with and without setCPU altogether, along with and without setCPU profiles but using the smartass and conservative governor. I always set the processor to 245-998 and never overclock.
I liked myn's Warm TwoPointTwo, so I recently tried that last week. Again, I'm getting okay battery life (~1.5 days) but with the usage I'm at I'm pretty sure I should be able to get 2 days easy. So I tried flashing Netarchy's 4.3.4 non-SBC CFS kernels with the same results. I've also tried with and without setCPU, along with and without setCPU profiles. Finally, I gave up and I'm currently using Netarchy's 4.2.1 cfs havs more smartass and using setCPU.
It's definitely not related to PRI 1.90 as I'm not getting the 100% partial wake time in Spare Parts, and I know the consensus is divided as to whether or not setCPU interferes with HAVS. I know all phones are different and ROMs and kernels interact differently on an individual basis, but I would really like to stick with myn's ROM and a good kernel to max my battery life. rather than go back to the stock ROM. Any suggestions on extending my battery life before I shamefully reflash back to stock software? I always do a full data/cache/dalvik before flashing a ROM, and wipe cache/dalvik before kernels.
myn's warm TwoPointTwo RLS5
netarchy-toastmod-4.2.1-cfs-bfq-havs-more-smartass
PRI and NV 1.90
setCPU 245-998 conservative
setCPU profiles:
temp >50*C = 245-499 powersave priority 100
screen off = 245-384 conservative priority 98
charging AC = 245-998 smartass priority 96
charging USB = 245-998 smartass priority 94
Try recalibrating the battery. Charge to 100% and leave it on the charger a little longer. Then turn the phone off and boot into recovery. In recovery wipe battery stats - in Amon Ra it's under the wipe menu. Boot back up & use the phone normally until the battery drains completely, without charging the phone at all. Some people say until the phone turns off on its own, but I'd try to avoid that. Just get it as low as you can. Then once it's dead, charge it fully without breaking the charge until it's completely full. You should see an increase in life after that. There's also an app in the market that clears your battery stats. I believe it's called "Battery Calibration", but I could be wrong about the name.
Since you don't use your phone much you'd be a good candidate for undervolting. If you don't want to undervolt while the phone is in use, just use a screen off profile only. Turning radios off while you don't have a signal or you aren't using them will make a huge difference as well. Let us know how it goes

I've heard people recommending a battery calibration after flashing a new ROM. My battery has seemed to be jumping down a few %ages and then stabilizing for long periods of time at a single level. Perhaps this is what I'm missing. I'll give it a try tonight when I recharge and see if that helps. I may try undervolting, but seeing as I got great usage on the stock ROM with the same CPU range I'd like to stick with 248-998. I always have a screen off profile though (as noted in my first post). I've also heard about people shutting off radios and such but I don't think I'd want to take it to that extreme -- maybe if I get desperate enough to eek out that much juice I'll give it a shot.
Bonus: to alleviate my problems at home since I have terrible reception and I know that eats the battery, Sprint is shipping me an Airave free of charge! In the process of trying to contact Sprint's CS (*2 on the dialer), the phone was force closing *1 and *3 work fine, as does normally dialing so I guess the problem is only limited to *2 (I even rebooted and am too lazy to reflash just because I can't speed dial a number I rarely call). Hopefully with your suggestion, I can get back to insane battery life
Don't know if this will help you out at all, but here's my setup...
myn's Warm TwoPointTwo (RLS5)
Net's toastmod-4.3.4-cfs-havs-more-sbc
Launcher Pro Plus
SetCPU:
Screen Off: 128 max, 128 min conservative
Battery<101%: 499 max, 128 min conservative
MinFreeManager:
Set to Aggressive
Twitter, Flikr, and assorted useless (to me anyway) apps frozen with Titanium Backup
Unplugged at 0700 and as of 2205, my Seidio extended 3500 battery is STILL at 74%
Average usage day, with tons of emails, and SMS/MMS messages. About 2 hours of web surfing and 3 hours of Pandora, but not a lot of phone calls today though. About 7 hours spent on WiFi, the rest on 3G (No reliable/stable 4G near me yet).
Background data off
Auto-sync off
Enable always-on mobile data off
I have noticed this is the best battery kernel I have tried out of all of Netarchy's (ymmv). I've had this kernel for 2 weeks, and getting 2 days out of it with HEAVY usage is no problem. I only lost 4% of the battery from 2300 last night to 0700 this morning with the phone sitting on my nightstand.
It seemed to not last as long at first until I wiped battery data and started from scratch. Always a good idea to wipe battery data when swapping ROM's and kernels I notice. Also read (here, of course) that new kernels have a "break in" time of a few charging cycles until they settle in.
Overall:
Completely satisfied with this setup. ROM is lightning fast, and battery is a non-issue with this kernel. Only ever so slightly laggy when opening Handcent or galleries (when I add pics and albums have to rebuild the thumbnails), but what the hell, it's only running 499mHz! Even fired up Avatar from my SD to check for stuttering, clipping, or audio lag. There were none!

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!
I had charged it so much that upon disconnecting the charger, waiting for the green light to go off, then reconnecting the charger, there was NO amber light. Straight to green. Tried it a few more times, with the same result.
Did it actually "supercharge" the battery? Who knows?
Did it take 3 1/2 days of use to break the 25% remaining mark? Yes it did!
So if you are bored, I mean CRAZY bored, what the hell! Give it a shot...

Thanks, but not willing to step into the realm of SBC kernels. However, I will try to go through a few charging cycles to see if my current NA kernel just needs to get broken in. I've also tried the charging method you stated above and while I did get good results, I'm unsure as to whether or not this is overcharging the phone so I decided not to do it again.
Anyways, I wiped batt stats last night after getting the full charge, so still on the drain and need to recharge to 100%; will report back after I go through a few cycles of charging.
Why not an SBC?? Because it fully charges your battery closer to 100% than a non-SBC?/
And don't buy into the hype of exploding batteries. That was handful of cases, that a) were all reported in the earliest days of SBC development, none since and were never fully attributed to the SBC kernel.
Also, you people that say drain til it dies, you DO realize that HTC STRONGLY recommends NOT doing that. According to HTC, you shouldn't recharge until you get below 50%, and no, I'm not gonna go look for the links, use the search feature.
I have a good method in my signature. Give it a try.

Can't argue with a battery that stays at 100% for 3+ hours then slowly drains versus unplugging it at 100%, blinking twice, and seeing 90% remaining...

Well, I'm no developer but if Netarchy says to beware in his latest kernel thread, even if for liability reasons, then that's good enough for me to stick with non-SBC until an SBC kernel is proven to be 100% safe. I think that's a perfectly valid justification to not use SBC for now.
I keep forgetting that we're not supposed to completely drain the battery. I guess I'll recharge when I hit 5 or 10%.
I'll take a look at your thread when I get a chance.

All threads (for the most part) say that, even ROM threads about not being liable if anything happens to your phone. Not even flashing a ROM is 100% safe but you do it anyway.
I've been using SBC since it was being tested the first time and I've never had one issue. No batteries have exploded, no chargers bursting into flames, and no phones have self-destructed.
If you want really good battery life, good performance, and want to try something other than Sense, CM7 and MIUI are really good ROMs. I would recommend Tiamat kernel (use 3.3.8 for now, 4.0.0 has some issues) and make sure to wipe batt stats and do a battery calibration. For good measure, you can try my BSM mod in my sig for even better battery life.
kings kernels are awesome!! im using one and is giving me 30 hrs!

Yes, all threads use the release of liability clause, but NA specifically states in his most recent thread that SBC could potentially cause problems.
Gosh, so much peer pressure! I'm not saying I won't ever go to SBC, just when I feel like it's a bit more stable and all the kinks are worked out. Kind of like you probably shouldn't buy the first model year of a car since the chances of running into glitches is much higher than if you waited a bit for the bumps to get smoothed out. If I'm being paranoid -- well, it's all in the interest of my $200+ phone. Regardless, I appreciate all the replies.
I've heard about MIUI here and there. I guess I've stuck with Sense since that's all I've ever known, but maybe I'll start branching out to AOSP and MIUI. Does CM7 have full functionality now on the EVO?
I'm on my first recharge since wiping stats and it's the fastest recharge I've ever seen. Maybe I do need to just break the kernel in?
I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing
check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

I used the battery califration app if that's what you mean.
Thanks for all the help guys, i'll check out some Kernals.

Do you have link for this? I'm running 7.0.3.. but I dont think im finding the correct Kernal.
Mugen 3600mah = better battery life...
Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

I rooted my incredible about 2 weeks ago, and after jumping around from rom to rom, but finally settled on cm7. 1rc1. At first battery life was great, I could finally get through a full day of normal use. I'm running the stock kernel, conservative governor, 998/245, and a screen off profile of 384/245, and also on the conservative governor. Then I read something about wiping battery stats yielding better battery life, and so I looked up exactly how to do it, and now my battery life went way down. Can't get close to getting a full days use out of it anymore.

How did you do it? Maybe you did it wrong. Also it DOES take a couple days for it to fully re-calibrate, so give it a few days too if you haven't.
I charged the battery fully with it powered on. Then turned the device off and plugged it back in and waited for the light to turn green again. Then I booted it into recovery, and clicked wipe battery stats, and re booted the phone. Once it booted up I unplugged it and used it normally all day until the battery died and the phone shut itself off. Once I did that I plugged it into the charger and let it fully charge.

Sounds like you did everything right. I say give it 3-5 days (I know a long wait) but usually that does fix a lot of calibration issues.
and there's a calibration app? craziness! I must see this..
If you are still having battery life issues, I suggest you install Chad's latest stable incredikernel (7/06/2011). I use it with CM7 and get very good battery life. You might also find juice defender helpful; set it to aggressive. Also you may want to manually adjust screen brightness settings.
Yep... There is a battery calibration app and it really does work. Wipes the stats for you and rewrites them. Just search the market for battery calibration. Should be right at the top.

The nice thing about the kernel is you can flash a mod onto it that will charge the battery FAST. (If battery life is gonna suck, at least gimme fast charging!) Not sure its on the thread. It is on his blog page at incredikernel.com.
Battery life is back to normal. Just for the heck of it I did a full wipe, and and re installed cm7. 1 in recovery instead of rom manager, used the calibration App, and went thru 2 charging cycles. Thanks everyone!
The more I get to know my rooted inc, the more I wish I didn't do the 2.3 update on my inc2 and could root it right now

I've updated the radio from the 7.28, not only is the upload/download speed better but so is battery life.
You have to try different ones as they are dependent on your location.

Checked out his site, and plan on trying out that kernel when i get home. Has anybody tried his incredicontrol app?

Yep, it's freakin great! Lets you toggle USB fast charge and audio boost, as well as control voltages. Works perfectly for me.

Awesome. I'm going to flash his latest kernel and try it out. I'm gonna have to look up how to adjust the voltages correctly for the best results
Sent from my ADR6300 using Tapatalk
There isn't really a "right" way to do it, per se. This is what I'd recommend: on the voltage control screen, there are buttons at the top to increase or decrease the maximum and minimum voltages (in increments of 25). The top buttons apply this change to all frequencies instead of having to adjust the voltage on each individual frequency. I'd try dropping all voltages (maximum and minimum) by 50, and see if your phone is stable that way. There are apps that you can use to do a CPU stress test (setCPU does this), so try that and see if you run into any reboots or anything. If not, keep dropping the voltages (I'd do this in increments of 25) until you run into instability. Use the lowest possible voltages you can with your phone remaining stable and you should notice some increased battery life.
Hope this helps.

OK, thanks. Does the stress test on setcpu stop after a certain length of time? If not how long should I let it run?

I let it run for a few minutes. Just press back once and it will say how many milliseconds it was running and if there were any errors.
I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.
Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom
Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/
You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.
Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/
Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

I had an Evo, loved it,but the battery was trash,even when I bought my 3500 mah battery, the juice in it wouldn't last a whole day,sorry man,there's just no hope for that phone,without undervolting properly

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.
