Ok when i first got my evo stock it would go from 100% to 60% battery in 20mim. Now im running CM7 with savagedzen cfs kernel and i have the cpu oc'd to almost 1.2ghz and i have a 25mv undervolt thanks to viperboy. Now my battery will go from 100% to 80% in 20mim which is still horrible. What else could i try to get the kimd of battery life that everyone rants about with savagedzen?
Ps. I really do not want to flash my radio. Im terrified of bricking my phone. I bricked my hd2 because of a failed radio flash.
Find a method you can live with that will fully charge your battery. I am one of the many who believe that the algorithm that determines battery charge is flawed. Personally, I charge my battery until the LED turns green and then I unplug for 60 seconds. If the LED or battery monitor widget does not display a full charge afterwards, I repeat the process until it does. After that, my battery life is awesome. Give out a try.
posting & replying from my EVO 4G
Well my phone usually drops to 99% within a few sconds. I am desperately trying to figure this out, Ive come so far, and have done so much with this phone, but to be stopped by something so trivial.
If I can be sure a radio update would help then I may have to, but I have no idea how to on the evo, or how to find the correct radio. Can anyone make any reccomendations? Should I try to flash? if so what radio would be a good start? are there any other things I could try aswell?
Here are my current specs:
ROM: CyanogenMod-7.0.3.1
Kernel: 2.6.38.6-SavagedZen-2.2.0-CFS
Base Band: 2.15.00.11.19
CPU: 245min-1190max
Undervolt: -25mv (Vipermod) (Crashed when set any lower)
Governor: Smartass
Brightness: ~40% (No Auto Brightness)
And I never ever run any task killers, I only use MultitaskingPro to switch between running process.
Try tiamat sbc kernel

Your setup is pretty much the same as mine.
Try this:
Download "Battery Monitor Widget" from the market and charge your phone until the phone's light turns green and the widget says 100%, tap the widget and wait for the current to display "8mA," you phone will be fully charged by then. My phone will usually stay at 100% for at least 5mins and drops to 99% after 10mins of use.
Also try using Savagegen governor instead of smartass.
Let me know if that works any.

With the newest PRI quite a few people have had their up times and awake times as the same number, implying that the phone isn't sleeping properly, which would of course amount to poor battery life. I had the issue once, and flashing an older PRI fixed it. Check your up time and awake time to see if they are the same or look suspicious.

download PRI 1.77_003 and NV 1.90_003 and flash them through recovery, I used Amon Ra for amend scripting and went away from Kernel/ROM manager.
Charge your battery to 100% with the phone, then turn off the phone and charge it again with it off..when the light turns green, unplug it and wait for the green light to turn off, then plug it in again and wait for the green light again.. when it's done, Hold the volume-down button, then press the power button and hold it down to get into bootloader then recovery.. clear batterystats.bin, then power off the phone again and plug it in again until the light goes green. Power on the phone and drain the battery completely until it powers off, this will create an accurate batterystats file for the full capacity of your battery.
Make sure you've optimized your settings for battery life, uninstall bloatware, turn off auto-brightness.. haptic feedback if you can live without it, turn off roaming.. find programs to list apps and CPU/Network usage and see which ones are use cpu/network and kill them/uninstall them.
You don't need to do any of that. Just click the link in my signature. you have to condition your battery.
BTW, overclocking is a battery killer....
This may seem like a stupid question, How do I check the up time and awake time? I Went to [Menu]>Settings>about phone>status> and the only thing there is uptime there is no awake time, or any other times....

That only shows on a sense rom. Cm7 you can see awake time on the battery usage graph
Overclocking isn't doing you any good. Especially since you're overclocking and undervolting at the same time. Try setting the CPU back to 998, if you really need to overclock constantly then there's probably something going on with your phone.

Turn off background data. Use it when u need it.

OK, So
-Im making a backup right now, getting ready to flash Tiamat 4.0.4 sbc. Also is Tiamat CFS or BFS, it doesn't say?
-I also dropped the clock back to 998(I have no real need to OC) With the clock dropped back im gonna see if I can drop to -50mv with vipermod. (-50mv was unstable with the oc)
-Im also going to continue to keep an eye on my up/awake time, but as of right now when i checked it they were the same. But ill keep an eye on it throughout the day. (They are both solid blue bars)
-Lastly Im going to bring a new new battery to the party.
Ok.....So ill keep you guys updated.
PS. My wifes evo has the exact same battery life issues as me, and her up/awake times are completely different. also is there a way to actually get a percentage or time? I hate just having those blue bars to go off of.

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.

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

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)
Seems like I loose 1 percent every 2 to 3 minutes re calibrated my battery no 4g wifi gps stock Rom rooted any one else experience this?

go to about phone, then battery. see if awake and on time is the same. if they are, bad. then go into battery usage, and see what the graph looks like.
then open up spare parts, go to battery history, hit the top box, and select partial wake usage. see if anything is not normal aka filling more than a few pixels at all. then check all the other top box options to see if anything isnt normal. then we can diagnose.

What exactly causes this? Every once in a while my battery, which is normally fantastic, seems to spring a leak! I installed spare parts and check it from time to time to make sure nothing is going bananas on me. Today I noticed that within about 5 hours of unplugging my phone, two quick calls, and a few texts, my battery was down to 65% (and still falling). I checked spare parts and under "other usage", it shows "running" 100% since last boot. Partial wake usage shows android system nearly full. This doesn't look right, and it certainly isn't acting like it does any other day.
I'm currently using ultimate juice. I have system panel and watchdog but I honestly haven't even reinstalled them since I rooted a few months ago. (Battery has been that good with MIUI...) Maybe I should??
Spare parts is new to me. Just downloaded it the other day, then this battery thing happened, and while scanning the forum just for ****s and giggles as I do every evening, I saw this post. Could somebody make light of this for me? Thanks...
same problem here i was unplugged for five mins and i lost 4 percent battery! hate it!
srry but most battery problems which have no solution are from a bad match of kernel, rom, and phone. just keep flashing stuff until your phone likes something. thats why some evos (even never rooted) get 1300 quadrants and 30 hrs battery and others get 800 quadrants and 5 hrs battery.
edit: if there is a problem though, then it is fixable. i just dont know much more on how to find it besides that....
Yeah some days are better than others

Hi I've been looking around to find good kernals while running cyanogen mod 7 rc4. Some of the kernals I install like netatchy gives the screen a weird flickering. Can someone suggest a good kernal that's overclockable and stable. Thanks
Netarcys kernel really isn't for cm7 that's probably why its flickering. You should try savage zens latest sbc or non sbc kernel or tiamats sbc kernel both are pretty good. I'm running the tiamat sbc 3.3.4(great battery life) and I'm pretty happy with it.

In a nutshell, sbc is a method of charging that allows you to "fully"(trickle) charge your battery. Normal kernels really only let you charge to about 90% for safety measures; while sbc lets you fully charge letting your battery completely fill. There's a few threads that talk about it if you search around to get more "details". I've been using them for months without any problems whatsoever. Good luck

That happens to me sometimes but not all the time. I believe that's still a problem with cm7 in general though. For best results I recommended going to settings/ cyanogenmod settings/ performance/CPU settings then use the "smart ass" governor. It has provided me with the best overall battery/performance. I also have my min freq at 245 and max freq at 1152.
Those are also my settings, I've discovered my evo can't go beyond 1.15ghz without locking up. I've been trying to get to 1.2 but no go

I just wanna correct this misconception because it led me astray and it took a good amount of research to realize this was wrong.
All kernels will charge the phone to 100%. That's not an issue. What happens is, once they are charged to 100%, they start draining battery again, and coupled with the fact that li-ions inherently lose charge over time, and the fact that most people haven't conditioned their battery's memory by properly charging it, by the time you pull your phone off the charger it's already lost that 10% (give or take).
Trickle charging hopes to fix this by "trickling" a small charge into the battery constantly once it hits 100%, to compensate for discharge, so that it stays at 100%. The problem with this is, it pushes a current through the battery constantly, and that tends to shorten the life of lithium-ion batteries over time. You may get better immediate battery life off the charger, but you'll kill your battery quicker. Come months from now, your battery life isn't going to be what it should, whether you notice it or not.
If you want to minimize the discharge, you can take a couple safer steps:
- Condition your battery. Charge it to a true 100%. This will mean turning the phone off and on a few times while it's on the charger to make sure it's actually at 100%. Then completely discharge it until the phone cannot turn back on. Do this a couple times in a row, and repeat every month or so. This conditions your li-ion battery's internal charging memory so it knows its true charge potential.
- Charge your phone while it's off. It won't drain nearly as much battery this way, so when you're ready to take it off the charger it'll be much fresher.
- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.
In short, SBC kernels are bad for your battery.
---
Also, Savaged-Zen 1.0.1 BFS no-SBC has been the best kernel I've found for the Evo 4G. Granted I haven't had this thing that long and there may be another gem lying around somewhere, but given the popularity of SZ, I doubt it. It's a very good, smooth kernel. It's giving me the best performance of what I've tried (most of the popular ones).
As for CFS vs BFS, flip a coin. Some will swear CFS is smoother, others will swear BFS is supposed to be smoother. BFS gives me more responsiveness personally, but I think it mostly depends on your workload. I keep scarcely-used tasks killed and I don't use widgets, so the lack of many processes may be what makes BFS better for me. Try both and see which feels smoother in daily use.

- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.

Thanks for all the info! I'm just gonna try SBC for a month then try non SBC for a month and see witch I would prefer better. Also for the Zen kernels do they break anything that's not already working? And would they give better 3d performance then the tiamats kernel?

That's a great plan man. I visited the savage zen kernel thread earlier and some are complaing about their newest build causing charging issues or something along with 100% wake time idk. If you give it a shot use their 1.0.0 instead of the 1.0.1. Just give the kernels about a week and see how well they hold up. Its mainly about personal preference(sbc or non sbc) I'm actually testing the tiamat sbc but I was previously on savage zen. I like to give all kernels a chance(1 or 2 weeks) to see how well my phone performs with them.
Ok well ill just wait till Friday to install a new one then and see how the Zen works out

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.
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?
Sent from my ADR6300 using Tapatalk
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?
Sent from my ADR6300 using Tapatalk
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.
