[Q] (kernel) battery saver - 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.

I may be fairly new, but I'm pretty sure this should be up in the Q&A Section, no?
Anyhow, I guess it all depends, not all EVO's are made the same... Experimenting and tons of testing is the failsafe route. If there were a single, uniform easy-peasy kernel that allows the user to save battery life by just flashing a Kernel, then I guess there wouldn't be much fun in development anymore, no?
Personally, I got the best battery life from the Fresh 3.3.0.1 ROM and KingxKlik's Kernel #11 CFS, but I switched to CM6.1 and used the CMSnap 7.6 Kernel and got a decent 8 hours of heavy usage.
Sorry answer so vaguely, but it's from my noggin and experience (so far) wit XDA-Forums

What to use[KERNEL]for myns rom w/collins tweak?

I was told on the guide that it works best with nohavs kernel but im using the 4.2.1 by netarchy cfs,yet it gets to 70% in an hour with light usage.
And im a pretty heavy user.
I know he posted the recommended kernels that work on the rom but I need to know what works best with the tweak for the optimal battery life and smooth and quick. Because the kernel im on now is not smooth nor quick. A bit laggy actually.
Please im in need of help,don't flame or just leave.
(I know this will be moved but i need your guys help)
What's your opinion?
I need assistance.
Thank you.

Hey bud, instead of posting about this in THREE different places stick to the Q&A section OR the Myn rom post! Im not going to be a total @$$ hole about this, but wait for it someone will be. It gets obnoxious reading your exact same post in three places. Thanks and have a nice day.

You should really utilize XDA's search feature more! Instead of using the battery tweak, you should use something a little simpler for battery savings like setCPU or CPU tuner, both of which can be found on the market. Just having a profile set for screen off makes a huge difference, assuming you allow your screen to sleep. In the end, a little bit of reading and personal experimentation goes a long way in becoming more competant and knowledgeable about your device.

Best rom for battery life

I just got my droid incredible and I rooted it as soon as I got it. I've tried almost every rom in the "official rom" thread. I can't seem to figure out which one is the best for battery life. Right now I'm on myns 5.2. Any insight would help.

I was using miui au 1.1.7 and had great battery life. Miui isn't for everyone though. I just installed the latest cm7 gb build so well see

It really depends on the kernel that is flashed with the ROM as well, in general ROM's that are AOSP tend to have better battery life because all the Sense stuff that syncs constantly can drain your battery, but alot of devs have found ways around this by getting rid of the extra Sense junk.
But IMO switching kernels gives the biggest difference
Happy Flashing
it trully is in the kernal and somewhat dependant on the rom.. like dude said.. warm is a badass rom.. i think i'm still using warm rls4, forget which kernal.. but find a decent one and use a cpu tool to setup profiles to control your kernals speed and usage.. with the right settings you can squeez some juice out...
lou's senseless rom with his #4 kernel is awesome
Skyraider 3.5 for sense or I'm having great battery life with cm7 w/ stock launcher (doubt it makes a difference on battery life but might)

Like others have said, it's mostly about what kernel you are using. Some kernels reduce the amount of voltage the CPU uses to save battery as well as underclocking it when its not in use to save even more battery. I've used Skyraider 3.5 with Incredikernel and it has given me the best battery life, and I've used quite a few different kernels.
If you choose an AOSP ROM (like cyanogenmod) try invisiblek's kernel.
Best battery life to date is my current setup, Senseless Redemptive Revolution with Lou's #6. I can get 24-26 hours with normal usage not watching what I do. Recently, I reinstalled Juice Defender, and as I have always been a skeptic of it, if it is set up correctly, I am seeing a very noticeable increase in battery with no real side effects. FYI.
For Me, it was Cyanogen 6.1 stable and invisbilek's #28 for the kernel, but play around with it and see what works best for you, now that you are rooted, you can add any rom and kernel that you want and find out what works best for you, rembember, everyone's phone and usage are different, what works for me may not be best for you.
Thread closed.
Reason: The reason we close what's referred to as "Best ROM Threads" is because the vast majority of the type end up a nasty flame fest. The reasons should be obvious. It's really a matter of opinion, and then you get the fanboys of certain devs chiming in, and well, you get it. You did nothing wrong (besides posting in the wrong sub-forum). My advice is try a few and make that choice yourself. It's easy to find the most popular ATM, because they stay on page 1 of the dev sub. That doesn't necessarily make it the best, however. Give some a shot and see what's best for you. Good luck.

[Q] Best Sense Kernel

So, been seeing a lot of new AOSP kernels being released, which is great because i have been using CM7...
However, i am trying out some new ROMS (sense) and looking for Kernels other than HTC#15 and Net's.
Lets keep the thread uncluttered... I am not looking for opinions of this is best or not... but just some other options that i can try out. If i get enough options, i can just update the OP and we can all use it as a resource... ??
Here are my priorities:
1. Battery life
2. performance
Battery life is by far the most important thing for me.
Any suggestions would be appreciated.
This thread should be closed ASAP. This is going to lead to multiple people suggesting multiple kernels and arguing over which is the best. One of the unwritten rules of kernels is "Do not ask which kernel is the best." You have try them out for yourself and give them a few days to settle in.

Ok.. will rewrite the OP, but i am just looking for options.. i will decide what i like, but the only options i am really finding are Net and HTC#15. There was not 1 mention of "which is best"
But thanks for answering my questions.....
It's nothing personal. It's just that theses threads never end well.
Try HTC #17 (Requires you to be on PRI 1.77 and radio 09.01)
or
Any of Net's, like you said.

I get it though.. i have spent my fair share of time reading through page after page of useless BS...
Best advice is to acquire the various kernels out there.
Try each one out for a few days to see what works best with your hardware.
Finally, don't forget to mess with governors and their settings. That will have a bigger impact on your battery/performance criteria.
I have only used one for 5 minutes, as I run AOSP, but the netarchy kernels are nice.

Right.. I get that and is what i typically do.. just looking for other Kernels TO try.....
HTC #17 (awesome, but best battery life when used on Myn's RLS4 or any pre-3.70 OTA based ROM)
HTC #15
The bajillion combinations of Netarchy-Toastmod kernels (seriously, there are a lot he's made. Static Undervolt, No Undervolt, HAVS, noHAVS, SBC, noSBC, etc).
Ziggy's (not a huge fan of these, but people seem to like them).
That's about it unless someone else wants to chime in.

Ziggy's kernels have a great balance between the 2 priorities, and battery life is great.
And just a suggestion, if you are not "looking for opinions of this is best or not". Then you might want to change the title of this thread, its a little contradicting.

click the go advanced button.
id also like a kernel for my stock 3.70. preferably one with an OC without the need for set cpu.
Ziggy works best for me but like I said that is just me, different phones seem to work different better with different kernels. It's all about what your phone likes

As crazy as this might sound having the BEST battery life is hard to find. I'm using a regular battery not extended so I found that no matter what kernel combination I use there really is no AWESOME battery life. These types of phones on a regular battery just aren't meant to last all day. It ticks me off when people brag and they say things like "oh my evo last all day and etc" . Why brag and you're not even a heavy user like normal people. Most the people who brag about their ultra battery life aren't heavy users, and their phones are always sleeping. I use my phone all day, constant texting, twitter, Facebook, tapatalk, and wifi web browsing from about 8am-5pm. When I say heavy I mean heavy. Around 5pm my phones usually about 20 or 30% and this is perfect for me at least. I get home at 5 so that's my peak usage. I've used about every kernel/rom/tweak combination that exists and I don't think aosp has better batt life over sense and vice versa. Right now I'm using myns 2.2 with the 4.2.2 net/toast kernel sbc with the 1.77 prl and my phone can go from 8am to at least 7pm with very heavy usage. This by far the best I've gotten out of my 004 evo over and aosp/sense rom especially with everything working perfectly. Cheers.

[Q] gingerbread-evo-deck [1.3][2.3.7 Stable] - Battery life questions

First off, thank you to everyone who contributes to this community! I have been on here for some time now and the help/information available in these forums is amazing!
I hope that I am not being a noob by starting this thread and apologize ahead of time if I am incorrectly posting this. As I do not have very many posts under my belt I am unable to post to the development thread nor does it seem according to the forum rules that I should be posting questions like this there anyway. The last thing I want to do is upset anyone in this fabulous community.
Now down to business!
I am running the "gingerbread-evo-deck [1.3][2.3.7 Stable]" and just have a couple questions concerning my final setup to maximize battery life. I am in love with this ROM and all things deck but do have a couple concerns. Battery life is fantastic for me while phone is not in use but the battery does seem to drain quickly while actually using it. I am currently using Tiamat_Evo-v4.0.6-sbc kernel and have been running it for about a week now.
Q1: Should I be using Tiamat_Evo-v3.3.7-sbc Kernel(or "Lee" as I believe it is commonly referred to)? And, does this kernel offer full support for wimax and hdmi? From what I gather this seems to be the preferred kernel for AOSP ROMs.
Q2: What is proxsensorfix.zip? I saw this as an attachment in the development thread. Is this the fix for the Android System spike in battery stats? Will this improve battery life, and is it compatible with this ROM? Are there any negatives to applying this fix?
Q3: I think I have seen it mentioned that by downgrading the radio from the most recent release that battery life can be improved. Can anybody confirm this? What are thoughts on this?
Thank you in advance for any info that can be given on these subjects!

Q1: 3.3.7 SBC or 4.0.8 SBC kernels have worked great for me on Deck GB 1.3.
Q2: Not sure about proxsensorfix.zip, but the phone.apk w/o proximity is what I use, as I've heard the proximity sensor does use more CPU, which drains battery faster.
Q3: I'm using the latest radio and WiMax, and experience no problems whatsoever.
IMHO, Deck's 1.3 is the best ROM out there hands down. I've been using his AOSP ROMs from the start and have not been disappointed. PM me if you have any questions......
Have you considered using vipermod to undervolt? it will save you more battery

Thanks for the suggestion. I have not done any undervolting yet but was thinking about looking into it.
Okay, I'm pretty settled in on the Lee kernel now and have undervolted 50mv. Things are running pretty smooth.
Another question tho! Is the V6 Supercharger suppose to help with battery life at all? This is not entirely clear to me. And if not, I don't see much need for it as my phone seems to run just fine without it.
Also... android system spike in the battery stats, seemingly after a phone call. Is there a fix for that? This also is unclear.

[Q] Looking for the most battery efficient ROM

Greets.
Pretty much as the title says. The last costum ROM I was running was CM9, since then I've been running stock because I am using it as a dev device primarily. Now I've got another one with a cracked touch so I'm using that one for dev purposes.
Lately tho my main one seems to be draining my battery way to fast - esspecially when mobile data is on (which is pretty much all the time). It used to go for a solid day or a day and a half with data on but now it dies in about 5-6 hours.
So I decided to go back to costum roms now that I don't need a clean device anymore. Which would you pps say that is the most battery efficient costum rom out there? CM, Paranoidandroid, any other? Or better yet which kernel is best in battery efficiency?
Cheers for the answers
Mod Edit
Best ROMS/kernels are not allowed on XDA.
Please test these things for yourself.
This is the only way you will get an unbiased opinion,and then, you can decide for yourself if it meets YOUR needs.
