Kernel issues - EVO 4G Q&A, Help & Troubleshooting

What would you say is the best battery saving kernel? I need to go a days worth of battery , and I use my phone heavily.
I use jd mod 102310.
I'm currently testing kings cfs#8 but its dying fast why? I just loaded the rom after a full charge.
How long will the battery life start to kick in?
Please help me.
Advice is needed.

The funny thing about kernels is that it changes from phone to phone, I may get the best battery life with kings#9 and it might drain you're phone faster than there before.... I use calks 1.4 with kk#9 and I'm getting the best battery life I've ever seen with the evo. Else check to see if ur phone is sleeping properly.

I don't expect to convince anyone to go back to stock, but the newer ota updates and roms have fantastic battery life. I can't say that I have noticed any difference in battery life with the 3.30 but I haven't taken he time to observe. But 3.29 was a big improvement, or so it seemed.
I go about 40 before charging. And I'm a heavy user.

Rom and kernel help!!!

I'm in a dilemma! For the last week I've been hunting around to find the right combination of Kernels and Roms. Natively I'm a CM ASOP man. But I've tried everything from CM to MIUI to Ava to Mym. None of the roms are giving a decent amount of battery life. I've tried several combinations of Kernels also. My battery life has been as terrible as 3 hours. I'm talking about losing a percent every minute!
I didn't buy an extended battery. But I have tried a brand new regular battery to make sure that I didn't have a bad battery. Both batteries have the same results under all combinations of Kernels and Roms.
I've seen members braggin on having 12 to 18th hours of life under heavy use! How is that possible!? Lol! I know it has to do with device, kernel, rom combinations.
Can the awsome members of the GREAT Xda please help me out? Point me in the right direction. fyi: I have a ver 003 device and also I don't overclock much at all but I underclock to try and save a lil juice!
Thanks in advanced!

No matter what rom/kernel combination I run I get really ****ty battery life with the stock red HTC battery. For me personally investing the $70 or so for the Seidio extended battery on Amazon was worthwhile. I also purchased their wall charger as well.
I'm not going to blow smoke up your ass and say that the battery last 2 days with heavy use because thats BS. However, with heavy use (running emulators, gmail sync, occasional bluetooth for wii mote, texting, web browsing, etc) I can get through a 9 hour work day with a lil life to spare.
At least go on amazon and get a1800 mah battery. They are cheap but goood.

I just bought another stock battery and a wall charger, I keep the spare in my wallet and battery life is a non issue now.
Check out batteryboss.org before buying an aftermarket one though, most of them are rips offs.
I'm not sure about rip offs on amazon but certainly ebay..i bought two batteries w/a charger for $25..and a third one since my oem battery took a bath, fully charged.

I'm going to research some better batteries. I appreciate the intel. But my thing is I know I can get a few more hours of battery time with a simple kernel modification. Loosing 1% a minute is unheard of lol. Like now: I had 100% when I started this reply and I'm officially at 95% as I press Submit lol! Terrible

You should see if you can get a replacement battery from sprint. I am using CM7 nightly 24, and can easily sustain 24+ hours with the OEM red battery.
Everyone will have different results even with the same rom/kernel, however the drain that your experiencing does sound like your battery might be going bad.

I see your stats and that sh*t is wicked! I used CM7 and that one drains the quickest lol.... before I cash out on a new extended battery where's an abundant source of Kernels? I've tried three and I wanted to do a little process of elimination before I pull out my visa lol
Sent from my PC36100 using Tapatalk
There aren't very many CM7 kernel's available yet, so few that I can't even begin to tell you where to start looking, for Sense roms though, search for Netarchy those kernels work really well.
I see... I appreciate that! Imma give Mym a try with a few of them Kernels. Thanks again for the help
And what exactly is the Kernel that you are using!? Lol
Sent from my PC36100 using Tapatalk
Honestly, I've found that the right kernel makes the biggest difference and setcpu, juicedefender, etc only make it worse. For me (also 003 hw) kings kernel and htc # 15 uv have been best. I've had great success with azrael and vaelpak roms. Currently on vaelpak with kings # 11 with NO battery saving apps. I get 24 hours with my regular use. Yesterday was very light, I went 24 hours with just under 50% left.

This is what I've been testing for a while. This build contains auto bump charging based on the voltage as opposed to the full charge method. I don't know how it works on extended batteries yet...but works pretty good on stock batteries. With this, you should have a better chance of picking up the phone at higher voltages.

I flashed the ver 8 with CM6. 1.2. so far I've gotten slightly better battery life. 20 minutes and I'm still on 99%. That's a whole lot better than losing 1% a minute lol! I'm still going to do another exhaustive research to pinpoint the best combination!

I know you guys said that setcpu can make matters worse. Is it alright if I use it to underclock to 245x245 when the screen is off and if the battery ever goes over 110°F automatically? That's the only profiles i use to help with battery maintenance

If your still using CM7, it has its own built in setCPU, I have mine set to ondemand 245min, 768max, and sorry for the delayed response, I went to lunch, however the Kernel I am using for my CM7 flash is just the stock kernel that comes with the initial build if CM7.

Incredibly RE -engineered questions

So I've flashed over to incredibly RE-engineered and I heard about the great battery life and speed. I sure did have a more noticeable speed improvement but my battery life hasn't gotten any better. Any reasons why this might be? And for some reason I can't load any videos off hulu either. Anyone have these similar problems?

Everyone's battery life is different because everyone uses their phone differently. One person may get great battery life because they don't do much with the phone, and someone else will try the same, but they do a lot of streaming, web browsing, etc and have horrible battery life. It's all trial and error until YOU find the combination that works well for YOU.
And the hulu problem I believe there is a fix for it in the thread. Search the thread for Hulu and you should be able to find it. (I am not sure of this because I don't use the rom, but I believe I read something about it when I tried it out.)
Battery life if tough to compare due to reasons above. When I was syncing a corporate email account via active sync I was getting 9-10 hours o this rom. I am no longer using active sync and right now am at 15 hrs 37 minutes since unplugged at 62%. Awake time is about 5 hours on this charge. This is with stock battery.
Exchange active sync is a hog.
I use my phone pretty often and Im usually texting and browsing on the net. But my battery life is maybe 6 or 7 hours? I haven't really gone all the way down to empty but that seems about right. Is that decent?

That's not quite good. On my stock battery I'm getting around 15-25 depending on use. Maybe check your settings for battery hogs?

I'm not sure what's wrong with my phone. My battery usage says that most of my battery is being used by cell standby and the android system. Should I reflash the rom and see if that helps? I want incredible battery life too this battery life is pretty much the same as a stock rom which is why I flashed in the first place : more battery life!
Sent from my ADR6300 using XDA App
I'm not a power user but I get better battery life with this ROM. Yeah, maybe you should wipe and re-install the ROM. I would then not install any apps and see what your battery life is like. Disable auto-syncing too. Maybe you have an app sucking the battery down.
Is there an app that i can download to monitor my battery usage? I know you can check it through the "About Systems " menu but I almost don't trust it.

Running a faster rom like re engineered, if battery life is super important, you can use setcpu to underclock slightly at all times, and lot at screen off. It comes with a lou's kernel, which he doesn't recommend using setcpu with, but I've always had great luck with king klix kernals, which also undervolt.

Serious question.. regarding EVO batt life

So not here to stir up this post with heresay and sayso facts or not facts... But this is my 5 th EVO since released goin.. back and forth.. I was just curious if anyone knows of a fix to the teribble batt life.. goin on over a yr now...since released..and all the trial and error ... Talk on flahing kernels ..certain roms.. extended batterys.. even partitioning SD cards..
Now there's threads on latest OTA KERNEL including first real trickle charge on the device ...
So are they're any good fixes /links /ideas that cure the issue ..etc.. such as Rom/ kernel combo ? Anything
Besides relying on extended batt

You should probably look into viperMOD. You can undervolt most AOSP kernels to save some battery but sacrifice a little performance. I actively use this mod and I must say it does save a tremendous amount of battery.

I mean, it all depends on how much you use your phone, and what you use it for. I keep my 3g on all day long, and using MikG I can easily go 2 days without charging. Before gingerbread, I was using Myn's 2.2, and I could easily go 3 days without charging.
My setup lasts all day without needing to recharge. And I don't have to turn off my data either. Flash various ROM/kernel combos, calibrate your battery, modify how often your widgets and services update, adjust display brightness, don't let erroneous apps run in the background, etc. Doing that to make sure your phone is setup properly has the single biggest impact on your battery life.
After you do that then you can start fine tuning with things like turning off your data/GPS service, using vipermod, undervolting, etc. in order to get even more life from your battery.

Did I FRY my CPU??

First of all im not putting down anyone and there custom roms. As I am an avid flasher of them and there great features..
However.. Ive noticed with every rom I flash, my battery life SUCKS. I know kernels are suppose to have battery saver mods, but never seem to work for my phone. The only way I seem to get great battery life is if I odin back to stock. Its seems to last forever on stock.
On stock.. I would average around 10% drain every two hours of moderate use.. mainly texting..
On Custom roms I average 10 to 15 % drain every hour with same moderate use..
My question is, Could Overclocking have caused this problem??

Quite possibly... And unfortunately, you have to test different Kernels with your ROM to see what works best, or just ask the Dev which Kernel they used when developing the ROM... That's a good way to get the best battery life because after all, that's the Kernel the Dev based the ROM off of. Another option is to check out Marcusants post on setting up your Kernel for your ROM, and I apologize if you've already tried that... I'm just trying to list options... I've had problems with different kernels on different ROMS... Well at least until Rodderik started making his Kernels with Viper ROMS... Then it started working perfect lol. How are you running your clocking? Conservative? Performance? Also, are you using SetCPU with an OC/UV kernel and the Voltage Control app? If you use the two together, it could cause a lot of issues, you'd have to choose one or the other.
On the other hand, I could be 100% wrong and it could be just your flux capacitor... You know how touchy those things are. Try chucking your phone over 88 MPH and see how that works. The next step is VERY important though... Whatever you do, don't forget to put your phone in airplane mode before you throw it in the air or it'll just fall right back down after a couple feet... Keep it in the air I always say.

Im hoping once I hit 88MPH it will go back in time to when my phone actually worked. haha
I usually just use the Kernel that comes with the rom..
However I have used Set CPU and Voltage control together once. I messed around with the setting between performance and conservative.
Orion, first off. If u remember how "beepers" worked back in the day, if u ever had one, that's how text messaging works. It triggers a small ping when being sent or receiving message. So text messages really hardly use power. As far as ur battery is concerned, try this method if u like, just to see what kind of results u get. Charge battery completely with phone on first and then off. Then boot into cwm and wipe ur battery stats. Then drain ur battery completely without charging it. Then completely charge it up, and then see how ur battery does.

Battery was ok when I overclocked.. went down hill after that. Except whenever im on stock EI22 Gingerbread and it runs all day.
On custom roms with stock frequencies I would still see a significant drain.
I don't think you fried it if it's still running fine on stock. I'd be more likely to think you're overclocking with an aggressive governor that is making your cpu stay at higher frequencies.
I havent been doing any OC or UV in months now and still have the problems on custom roms. Perhaps I got the phone that doesnt like to be modded.. Damn Sprint ha
also screen brightness has a HUGE effect on battery life. also do you do games and such? Those can be very draining as well. I am on a viper rom going on 14hrs and still at 78%. but i mostly text with my phone. about 15,000 a month to be exact. and use f.b. and xda pretty heavily. and different kernels can make the difference between 6 hours and 20.

i will say that my phone is particular on what rom i do run no matter what kernel i use
I just mainly text and surf the web occasionally. Funny part though the only game I play rarely is Deer Hunter Challenge which is a pretty high def large file game and when i play that my battery doesnt seem to drain. Right now Ive gone down 10% over the last hour just sending about 15 texts. And I have my display set to auto brightness
It's real simple...overclocking equals faster cpu AND faster battery drain. Do not overclock or do not complain about battery...one or the other.

Battery life poor except for stock

I give up.every ROM I run just doesn't have the battery life expected. Am I expecting to much? Not even Cauks or blazer el29 doesn't give the battery life as stock.don't get me wrong they are all great roms but at least for my device not battery friendly. I'll post some battery stats from BBS if anybody has some free time to see what's going on. I'm on Cauks el29 now.I format everything before flashing and I use cauks format all many times.

Well when is the last time you used stock? And if it's been quite a while...consider having your battery checked out. Anyway, I'll continue as if your battery is fine from here on out. Basically, anything but stock tends to have a modified kernel. Even with all the battery tweaks, etc out there, there's a chance that the kernel itself might not play well with your phone. I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?
I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

Agree, everyone have different experiences, I haven't try that ROM yet, I will test it out later. Have a nice day/night sir.
Sadly I have to agree with OP.
And the previous screenshots at 59% with 1hr, 36 screen on is exactly the issue.
Hard to compare your battery stats with mine since screen on time for my phone will be 4+ hours.
Since there are no standardized testing anyone can do with any rom, any speculation on which rom has better battery life or doesn't is just pure bogus seat of the pants gut feelings.
If there were a standard test that ran like. 5 minutes of mail with 20 mails received, 10 minutes download, 30 mins of playing the exact same video, 13 music tracks of the exact same song all with screen, vibration, brightness, etc all at the exact same level, you could get a real test, but, alas, nobody has a standardized test.
For MY usage, stock clocks in at the same as or better than just about any other rom I've tried, including all the various super scripts out there.
I guess I just overuse my phone!

I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?

Probably a good 2 weeks since on stock. I tried all ICS but i just used the kernel that it was packed with.THats a good time frame. What is the best kernel to run with roms?

I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

Wow thats some crazy battery life. yea ive been on it for a good week. pretty much i stay on it for a week or two and then i do a battery calibrate. what kernel do you use with the Mijjhs Goodness rom
Get a good gb rom and under clock that puppy to 500 or 800. Battery definitely lasts

Also if you use caulks roms flash his under volt script as well. I was using his -75mv script stable. Which equaled amazing battery life.

Sorry to disagree but that is not my experience at all... This is the m'ics rom and is typical of the battery life I get.

How did you get this type of battery life? please share the steps on how you rooted your phone up to the operation.
thanks man.

Thanks for your observation that I'm doing it wrong. What would be appreciated more than telling me your opinion would give me steps in correcting as to "what" i'm doing wrong

Things drain battery. This is my test off wifi for the most part using the phone as a phone with average use. Didn't even log in to Google on this one. Just proof that intensive applications, google services, and anything else added after a "factory flash" can manipulate battery life significantly.
Oh, and check out drain when I'm in less than ideal coverage. Noticeable difference. One huge factor to consider when diagnosing battery life.
It really depends on what you're doing with the phone. Obviously having brightness up playing heavy games with Wimax on will kill battery faster than someone on low brightness reading an ebook with wifi on. That said, i agree that I've had better battery life stock than almost all ics roms.
My life for Aiur
