[Q] Kernel Advice for a CM Noob! - EVO 4G Q&A, Help & Troubleshooting

Alrighty,
So, to make a long story short, I had been using Fresh Evo rom since about September/October. About 2 weeks ago, I went to upgrade my rom, and through multiple poor decisions and sheer stupidity, I bricked my phone. Anyways, new phone arrives, gets fixed, etc. I root and install CM7. I've been using it since Friday, and I very much like it. However, I do seem to be having a slight problem. I feel as if my battery is draining a lot faster than it was when I was using my 2.2 Fresh rom. I am planning on doing the battery stats wipe later on tonight. Anyways, to my question: What kernel options are there for CM7 AOSP Roms? I'm am woefully ignorant on the subject, and the searching I've done on the subject has left me more or less confused.
Many thanks,

To make it short and sweet, the best/ popular options are now:

My savior from my brick thread! Thank you! Follow up question: I was reading part of the Savaged-zen thread in the android development section and people were talking about SBC charging. Some of the stuff I've read has made it seem like it is a dangerous type of charging, while other are getting absolutely absurd amounts of life out of their batteries while using it
So... is it a SBC kernel? Is it worth risking messing up the battery? Any thoughts/suggestions/comments are much appreciated.

-Cape flaps in the wind- I have returned!
http://forum.xda-developers.com/showthread.php?t=894880 Best info on kernels.
Personally, I don't use SBC because 1: It can make your phone laggy at times, which is annoying 2: It can and has proven to be bad for the battery, in terms of leaking/exploding on people. Yes people have gotten ridiculous [not gona lie] nice battery on it, because it pushes lower voltages at time to get the max charge, so it actually takes longer to charge, but holds it longer. Great in the short run, bad in long term, but again, I personally wouldn't recommend it.

Hmm... A lot to think about. I'm using the default CM kernel right now. I pulled my phone off the charger at work around 2:30. I was using Wifi tether until 3:00. I've made a few phone calls, sent about a dozen texts, browsed around on facebook and what not. Found out that facebook was eating up my phone with 40 minutes of partial wake usage, made some adjustments so facebook *hopefully* won't do that again. Was at about 70% Rebooted the phone. I'm currently at 68% at 5:15. My room is also in a basement, so I'm sure my signal strength is fairly poor and that probably isn't helping either. Still, I feel like I'm going through this battery a little too quick for my tastes.
Maybe I'm going to have to look into getting the Seido 3500 battery, and cover, and car holster >.>
I'm going to try to give it a few days. I just did a battery stat reset, so I'm going to let it die, recharge, then see how it pans out. In the meantime--I'm thinking about checking out Savaged-zen. Maybe read through those 200 pages of posts :-\

Well give it a few days to settle in, and wifi tether is definately a power drainer, even for me and all users. I typically only use it when things get bad enough and i need to get on xbl, or download torrents slowly, cuz I'm at school >>. Also the spotty signal area definably doesn't help either. And if you check out the OP page, the first couple, and the last few, you should be okay. I'm having good life on the Tiamat kernel personally. Also, you can change your governor to smartass or conservative, both yield good battery life.

Help me revert to a pre-froyo rom

Hey guys. i've had it with Froyo. i have a list of complaints, but that kind of post has been done too many times.
basically i'm wondering how to "downgrade" back to a 2.1 rom. i started with OMJ's 2.1 "eclair" rom and now i'm running his 2.2 froyoized rom. i'd like to revert back to the latter. can someone clue me in on how best to accomplish this?
thanks!
I should expect it to be as simple as clearing data/cache/davlik and flashing the rom you want to use.
Don't think you can but I'm not 100% sure Idk what problems ur having but 2.2. Has been a beast for me

That's what I assumed. i just wanted to make sure before i screw something up.
@SporkMan, basically it seems slower, the battery life is awful and recently, i've noticed the phone itself is HOTTER. i carry it in a holster on my belt and this morning(while in court) i had it on airplane mode without GPS, wifi, etc on and it went from 85% battery to 42% batter in less then two hours and was hotter then it gets when i charge it off the wall adapter. i've NEVER gotten that bad of battery life. not even before i rooted it. thats just unacceptable.
plus, i haven't seen the talked-about speed gains in the applications, so it doesn't really provide me with anything new(correction, there is one thing i absolutely LOVE and that is the mass update in the Market. that just rules!)

you'll probably get a bunch of suggested roms to try, but my vote goes to BakedSnack and his Bkaed1 kernel. Hero tweaks the kernels to give killer battery - I've been raving about it ever since I switched over. I used to have to struggle to get over 13 hours battery - now I get over 20, without setcpu. You should nand and try it. If you don't like it, you can always nand back.

right! forgot he fixed that when he hit version 4 - I stopped using his kernel around 3.7ish when i went with Baked1. Sorry for the mis-info!
I would have to agree with the others. I use Fresh 3.1.0.1 and run Netarchy's 4.0.2 kernel, and my phone has never been faster, smoother, nor have I ever had better battery life as I do now. I took my phone off of the charger at 8:00 AM today, surfed the net, answered a few phone calls, did emails and messages for a total screen on time of about two hours so far. I also did 15 minutes of FM radio, and half hour of streaming Pandora on the way to work, and my battery is at 76% at 2:00 PM.
The other thing you might consider is that, it wouldn't surprise me if in a few months, aps compatible with the evo running 2.1 won't even show up for you in the market any more. I may be wrong, but something to consider.

Thanks! the part i'm MOST confused about is when i download the latest Baked Snack rom from that thread in development i only get a 318kb file. every other rom i've downloaded has been 125mb +. i don't really know what thats about
If you're talking about 1.2.5, the reason its so small is because its not a Rom. Check my link again. You have to wipe and flash 1.2 first, then 1.2.5 over that without wiping, unless you want the themed version (which I highly recommend) in which case you wipe, flash 1.2, then 1.2 themed without wiping, then 1.2.5 themed without wiping. It sounds like more of a pita than it is, and its worth it in the end.

Can someone help me with 1st time root for seidio 3500 battery?

Ok am a total noob I have no idea how to root and I guess I need to root to get the full use of the seidio 3500 battery I have ordered? Can someone help me with a step by step or a place to go? I am familiar with Macbooks so it has to be done on my mac. I really am only interested in getting something that will help me get the most out of the 3500 battery and maybe delete some of the apps sprint put on.
Thanks any help is appreciated. Scott.

rooting has nothing to do with your battery.
well then what do I do to properly use the 3500? I read there are battery kernels is that in the root?

Do this ^^^. What you're talking about are the hacked sbc kernels which among other things allows extended batterys to fully charge. But you do need to root first.
Sent from my blah blah blah blah
Just to clarify what's been said here, it is true that rooting has nothing to do with your battery. However, you do need to root to install a custom kernel, which could help with your battery.
Honestly, there are lots of guides and discussions here, and I think your next step is to read up on rooting, read up on kernels, and learn more about your phone. Rooting isn't particularly hard, but you can screw up your phone, and you void your warranty with Sprint by doing it (though you can often revert back to stock and unroot for service, as long as certain things haven't died). You also take on responsibility for applying updates yourself.
I don't know a whole lot about the extended battery situation and whether it truly doesn't charge fully without a custom kernel -- plenty of people are using it without rooting. That's not to say a custom kernel won't make it work better, but I don't recommend rooting to anyone who don't understand what it is, what it does, and what it means for support and over the air updates. Read up and see if you think it's for you. If not, I'd suggest you stick with what you have now.
To reiterate...The capacity of the battery and root have nothing to do with reach other. The battery will simply drain longer and then take longer to charge to the max voltage.

With custom roms/kernels aside, here is what Seido recommends doing for the 3500 extended battery:
Here is what we recommend if your having problem charging the battery. Please try to fully drain the battery until the phone completely shuts off automatically and then charge with the OEM AC charger that came with your device. Repeat this process 3 consecutive times. This will recondition and also recycle battery usage for best performance.
Thank you,

I haven't personally tried this because I'm running SBC kernel and my battery life is highly acceptable. Never dropped below 50% in a full days time even running Angry Birds for good periods.
Thanks I read that. I think I will just condition the battery as I have found numerous people that are unrooted getting awesome battery life from just conditioning the battery.
The HTC kernel was built for the 1500mAh battery without a custom Kernel thats all you will get and thats all the phone will think you have. This is also the reason they sell the docking stations with the additional battery charging units so you can fully charge those extended batteries since the phone doesnt. Now if you charge it fully on the docking station yes you will see a difference. There were a couple discussions about this in the past. As someone stated use a custom kernel with SBC.
Also, in regards to the SBC kernels, be aware that the jury is still out on whether or not this method of charging will damage the battery. There are a few discussions about this if you search these forums. It will be up to you to decide whether or not to use it.

Whats going on with peoples Evo???

Wondering what's going on with peoples Evo lately... Mine stopped working for 3 hours then came back on.... I went to sleep this morning and left it on the USB charger...Woke up and noticed that my supersonic was off and went through the normal routine of trying to get it back on..(battery pull, tried booting into recovery, pulled SD card, tried different charger) all to no avail.... Get to the store and the tech tells me my battery is deformed (even told me to feel the buldge, which I did not feel). Their solution was for me to by a new battery...they wouldn't replace and im covered with the TEP....just as I was about to purchase the extended battery cause they didnt have the stock battery, I push the power button and my phone boots... Walked out the store baffled but the phone has been working ever since...
I been reading similar stories and my simple question is what the hell is going on...

Probably something with the kernel, that seems to be the common denominator so far.
Almost all of us hack our phones in some way: rooting, flashing roms, flashing kernels, adding programs (like hulu, wireless tether), etc etc. Since our battery life sucks anyway, many of us charge our phones multiple times per day. Li-Ion batteries aren't exactly known for their stability. If you Google it, you'll find that they've been acting funny and blowing up for nearly a decade (the oldest news story I could find dated back to 2002).
Since we run our phones really hard, sometimes the battery bugs out for a little while, or dies completely. It was recently blamed on SBC kernels, but we're talking a very small percentage of users experiencing problems. However, it's the nature of the beast that sometimes the phone just has a mild heart attack and comas out for a bit. I would still replace the battery or at least take it easy on flashing things for a little while.
As our phone grows older, we have more and more options on what to do with it...and that's just super but over-flash too much and one line of code doesn't make it and boom, your phone doesn't turn on for 3 hours. Software is a fickle *****, so have fun but be cautious. Always check your logcats and battery monitors.
Thanks for this very logical explanation... Ordered new battery just in case....and will take heed to your recommendations..

Just saw you said your battery was deformed... yeah, that's why you don't use kernels with sbc. It's pretty stupid to honestly.
Check out a video on youtube of what they can do when overcharged.
And definitely get rid of that battery. That's not something you want to be using.

[Q] Best ROM for Skype?

Hi all
I'm so sick of switching ROMs on my EVO 4G!! My battery life seems to suck no matter which ROM I try. I've tested my battery; it's fine. What I'd like is to be able to use Skype (just chatting; rarely use voice on Skype) with my EVO and get more than 3 hours battery life. I don't use Skype constantly; just want to be able to use the phone for more than a few hours before it becomes a paperweight!
Right now, pretty much as soon as I log into Skype on the EVO the batt drops to 80% and continues to drop every 30 min or so. Forget web browsing or texting; that kills it so fast it's dead in 2 hours.
I'm running Deodexed 4.24.651.1 and have tried Cyanomod, Baked Snack, Stock rooted and they all suck for battery life with Skype.
Maybe I need a different kernel?
Any ideas???
Thanks in advance!

Maybe because it's Saturday. I'm surprised they haven't jumped on you for posting this in this section. None of the roms that are gingerbread will have the life you had on 2.2 unless the code gets released and the guys that make kernels can make new ones. Battery life on the roms vary but if it means alot you should try Calkulin's rom. He has an undervolting script built in that may work for you. If you flash a kernel from the 2.2 roms you might get better battery life but something will break in the rom, ie camera.
Awesome development work dude!!!!!! Cant wait to try it out. Where's the download link??
My first idea would be posting in the correct section, or, it sucks that Skype and battery life blow on this rom you developed.
Since that is over, are you wiping properly with a formatall.zip? Are you making sure to flash the correct kernels with the corresponding rom? Are you restoring any data with titanium backup?
Move this to the q&a and you will get the information you are looking for.

I thought you had to have 10 posts before you could post in the dev section?
simple answer - skype though awesome also sucks.
for example just think about a laptop. my 7 hr macbook pro dies in under 2 hrs when i'm video or phone chatting on skype... shouldn't the same be expected for a cell? you're getting 3 hours, albeit only chatting as you say, but skype has been and remains a highly demanding application which although is convenient and widely used IMO is poorly written considering it's cpu and battery drainage. compared to simple web based google chat w/ video I get far superior battery life. like i said, my opinion, my experience. and yes as mentioned, try undervolting or SBC kernels or both. My EVO has ranged from stock settings 5 hr life to deck's w/ tiamat sbc + vipermod approx 40 hours (the 40 was when it was honestly just idle most of the time, occasional call or text a little bit of browsing, i was sick so on laptop mostly- although typical moderate daily use I would still be above 20% before plug in before sleep)
as long as you mentioned it, anyone happen to know a stable skype apk with video that was pulled? i've tried different sources and a bunch of my usual roms and I either get only back camera for a little then crashing or front camera green fuzziness and crash instantly.
Why is it I needed like 10 posts to post here but this guy can ask questions like this with 6 posts? WTF?

First off, I apologize for this being here. I THOUGHT I was posting in the Q & A threads so please don't be snarky. I had the other thread open in another browser tab going back and forth looking for input. How it got accepted I don't know; as I said I thought it was going into the QA area. Sorry.
To altman, yes; I am doing a complete format/wipe and only restoring essentials via Titanium.
To 'crammed', try Tango; it's decent video chat, is free and is soon to be released for desktops too so cell to pc video chat will work. Tango is nice that it lets you utilize both front/rear facing cams (and did I mention it's free?). The big problem is trying to chat with folks who don't have cell access/unlimited minutes who need a desktop option like Skype, which is why I use it. With family in Poland and UK, Skype's the best way to stay connected for free for me but again, they don't have the same cellular access/plans so it's not possible to do cell to cell.
Thanks for the input
OP created his/her account before the 10 post restriction went into effect. The change was not retroactive.
tango is cool....i also use ClearSea...it's got the pc support so you can video chat between cell and pc...works pretty nice over 3g...

Next time please post your questions in the q and a section, dev is for someone who has something they have developed for the community to use. Thanks

You guys sound like he should be hanged for posting here. Lol people make mistakes, it isn't that big of an issue.
If battery life is an issue for you, you have a few options. You can jump to CM7 or Evo Deck and set them up properly. With either of those, you can flash a nice kernel and set clock speeds accordingly. Battery life is going to suck on any 2.3.3 Rom right now, because developers have no access to the source code for the kernel. HTC is taking their sweet time.
However, you can also look into extended batteries. I have a one I found on ebay for about $16, and it's wonderful. The phone has a little bulk now, but I am currently sitting at 16.25 hours off the charger, and I'm at 32%. This is also on Synergy currently, so there is no custom kernel or anything in use.
Just a few thoughts.

+1. It's easy to screw up when you've been up all night downloading and flashing the newest versions of your favorite ROMs or desperately seeking the answers you need. No need to grab your torches once the first 14 people have cried "wrong section" (most of whom then offer advice afterward, enabling much?)

I have a better question:
Why is it that someone felt it necessary to bump a post that clearly was ignored by everyone and put on the second or third page just to flame someone?
This thread went unnoticed with no replies for over an hour and yet someone felt that necessary.
That **** is just as bad as posting in the wrong section, if not worse.
i have been a member of this forum for about a year now. and as you can tell i have very few posts. The ones i do are simply to say thanks to someone who made an awesome rom/kernel/etc. I spend most of the time searching for the answers im looking for. perhaps if you looked in the right section and researched a bit before you continuously flashed your phone you would know what is going on with it.
gotta love people that just jump of the cliff because the guy in front of did...
Check out my sig, AOSP setup would probably help you with battery life. Current radios too

Can you elaborate on this a little? I don't necessarily wanna bump this thread, but being a Comp. Sci. major, this seems odd to me.. What does it mean for a kernel to 'set'?
Or are you talking about the collection of data for the accurate battery reading (batters stats)?

First off, I apologize for this being here. I THOUGHT I was posting in the Q & A threads so please don't be snarky. I had the other thread open in another browser tab going back and forth looking for input. How it got accepted I don't know; as I said I thought it was going into the QA area. Sorry.
To altman, yes; I am doing a complete format/wipe and only restoring essentials via Titanium.
To 'crammed', try Tango; it's decent video chat, is free and is soon to be released for desktops too so cell to pc video chat will work. Tango is nice that it lets you utilize both front/rear facing cams (and did I mention it's free?). The big problem is trying to chat with folks who don't have cell access/unlimited minutes who need a desktop option like Skype, which is why I use it. With family in Poland and UK, Skype's the best way to stay connected for free for me but again, they don't have the same cellular access/plans so it's not possible to do cell to cell.
Thanks for the input

Thanks for the tip. I wasn't directing the 10 post mark at you btw, more at moderators/XDA in general. My first account was locked for "spamming" I presume to get 10 posts whereas I actually spent hours answering ppl's questions in the q & a but I guess the short time frame wasn't liked. But I digress, I'm not so in need for cell to cell as much as a nice universal cell to cell/desktop cross platform and unfortunately skype is the most popular. My girlfriend as well as many friends/relatives also don't have the latest phones so the cell to desktop is wanted. for now I'm just sticking to gtalk, with isn't without it's errors either.

... Kernel to set meaning it takes a bit for it to settle down to the way it will normally function, call it "breaking it in" or like how you gotta drive a car a few thousand miles before your performance and MPG are where the manufacturer claims itll be... Yeah I kinda like the second analogy, go me!
Frequent flashing or flashing too soon sort of doesn't give the rom or kernel a chance because they haven't stabilized, often why some people praise while at the same time others curse a rom/kernel. Myself included :/ yikes. I found that to be true when deck was held up on his updates for almost a week and my phone was amazing, but I updated and went back into the loop of constant flashing so keep that in mind, if you're set on giving s rom and kernel a shot, give it at least a few days of the kind of use you NORMALLY would. If you're playing with it all day and it dies don't call it shotty battery life until you keep it in your pocket most of the day during the week. Not trying to berate anyone, I've done these same things myself, patience is a virtue after all.

lol reddy
I DID research the ROMs extensively; that's why I'm frustrated. I've tried so many after reading about how great they are. I'm not saying they AREN'T great either, just not working where I live. There's no 4G coverage already and 3G is spotty. Even if I don't load Skype at all I can't get 8 hours off my EVO before it dies.
When you rely on your phone for business like I do, even without Skype at all, you gotta be able to get through a normal workday or the phone's a pretty paperweight and not much else. Right now, I HAVE to plug it in at work or it won't last 8 hours and that just sux.

Well then the issue lies with the network not your Rom

Another battery life thread, they are justified!

Ok, I will keep this short. I have had my GNEX for a couple months now and have been on a quest for the best battery life I can get. My boss has the Razr (not the MAXX!) and when we travell together, he can go all day with plenty of battery left. Granted he is on stock and I am rooted but I usually underclock to squeeze more out.
Anyways, with that said and that this is going to be short...
I search and search and search and search and search, you get the point, for threads where this is being discussed. All I EVER find is people talking some ish about Pandas die or something and the mods close it because they say "yes there is a best one, its the one that works for you". Serioiusly? WTF. What does that gain us, besides everyone (the ones on the outside looking in and the ones on the inside looking out alike) wasting their time.
With that said, here is my point. I understand that everyone has different scenarios for what is going on and everyone has different agendas. But for most people here, they have had their phones long enough to use the same apps, do the same stuff day in and day out that when THEY try different ROMs they can report their findings. Like me for example I have had my best results with AOKP but I only tried Liquid and Xenon other than that and only Leankernel and Trinity so far. Now if someone else came along and said they saw THEIR best battery life on ROM X and Kernel Y and they tried my combination, it would give me a jump start. After all isnt that the point of a community? Besides people beating their chests about pandas?
Rofl, pandas die. Also, this has been done many times in the past, everyone totes different combinations. It's almost pointless, the only reason you don't see all sorts of opinions on these threads it's because people recognize how much of a waste of time it is. I cannot tell you how much "you're mileage may vary" actually comes into play here. You just have to flash what you want to use, and often times, the effect of ROM on battery life does nothing but you perceive it as being helpful, because you enjoy the experience of the ROM, this "placebo" effect also haunts the forums. So the only thing you can be sure of, is when your battery life it's considerably worse than before, just wipe, flash new rom/kernel and try again.

The reason he can go all day is because his phone has an extended battery. I think its like 3000mah or something. If you have the gsm version its only 1750 do the math of course his going to out last yours. There is no best ROM for battery. Or kernel. Its how you configure said ROM or kernel. If you want a setup to go buy visit the link in my SIG about my Franco setup. I get relatively great battery life as anyone that knows me will tell you. Also manage your networks. Do you toggle data when not in use? Do you have things syncing? How often? What apps are running in the foreground as well as the background?

1) the razr screen is not the same as the GN. there are more pixels per inch on the GN than the razr.
2) you can never have the best combination. every phone is different. my verizon gnex i had cant handle overclocking past 1.4Ghz. ive seen threads on this forum where people have gotten to 1.8Ghz.
what works for you, will not always work for me and vice versa.
Go to location settings and uncheck Google's location service and GPS satellites. Open app drawer and navigate to the settings widget, long press to put on homescreen, select Location services when prompted for widget type (so that you can quickly turn those on for Maps or Navigation.
Presto, decrease idle battery draw from 2 to 3% per hour to 2% every three hours.
