ROMs, Kernals, & Battery usage

Been running SkyRaider 2.5.2 Vanilla for a couple days, now. Test drove some Hydra Kernals and didn't find one that didn't either lock me up or eat my battery alive for some reason. Did the battery-reset thing yesterday, just to make sure THAT part was okay. This morning I was down to 73% within an hour of unplugging (I did my usual procedure of unplugging in the morning, checking email and whatever, then plugging back in while getting ready for work: green light/100% when I walked out the door).
Next up is SR Sense with the modified stock kernal. I'm not looking for anything extraordinary in battery life, but I sure don't want to go BACKWARDS.
Anybody have any thoughts on ROMs / kernals they'd like to share?
(Mods: if this is in the wrong forum, I apologize. Feel free to move. Just seemed like development issues to me.)

Hydra undervolt kernels work fine.
This needs to be in general...like half the other threads on this forum..

Hehe . . . Yes! It seems to be a running "theme" around here. Look, now the thread qualifies for themes :|
Only stock processor scaling is going to be decently fast and not too heavy on the battery.

Opinion on great rom/kernel with good battery??

So I am looking to change roms. I am on BS 1.8 now and sick of the whole mess of them only using their forum and having to pay to get files, so I am looking to switch.
What rom/kernel are you all using that's giving you great battery life, high quad scores? Please post your configurations, so I can make a decision. Oh, no CM6...I like Sense.
I have been looking at
Virus Anthrax
Calkulin's EViO 2
Frost
Burnt Droid

Still happily rocking my Fresh 3.3.0.1
I donated to Damage, but he seemed to release a rom then take a 3 month vacation.
I donated to Fresh to get the beta stuff, but his roms are just rock solid, great battery life, fast, and I just don't have to mess with it. I did flash a new taskbar and back to standard rosie.
I am not a fan of the donation stuff. I can understand why they do it, but it seems to contradict the community. I have a lot of respect for these guys for what they do, I know it takes a lot of time. But its a hobby they choose to get into. They make a decent product, get some people following them, then they want to make it their job and get paid for stuff just doesn't seem right to me.

I still swear by Fresh(have since the beginning) enough to donate to him. I decided to switch it up for fun and now im on myn's Warm twopointtwo....Its just as solid, smooth, and battery efficient as Fresh but to me looks sexier and has beautiful transitions.

Ex-BSer here. I'm test driving myn with King's #9 kernel. I like so far. I am looking forward to RLS2.

the funny thing about sense based roms. There isnt a ton visible differences between them. a lot of it is behind the scene tweaks. and even all those are usually very minor differences in performance.
Basically what i am saying is it is all a personal preference. I have literally used every rom currently out for evo on this forum. most of them preform comparable real world (one may get a slightly higher bench blah blah.) there are a few "minor" differences between most of the up to date roms that may sway you but over all i would be willing to bet most people wouldnt be able to tell a difference in actual use of most of the sense roms (though i am sure many will claim otherwise i am sure but placebos work for a reason and the general public think the iphone is the best phone for a reason and none of which because it is true)
AOSP is different however as it doesnt pertain to this post wont go there. as far as the look of the gui if you look through the themes section you can normally find a comparable look to go with any rom (ie a lot of them use manups) so i normally tell people instead of asking to just play with them and see what they feel works best for them. Everyone will tell you there favorite rom is the best and will swear by it many having never tried the others. SO try the big ones and see which one you like is normally best some of the big sense based ones are
Virus, Fresh, Evio, warm twopointtwo, DC(though it is fading fast since it is getting) pretty out of date)
all fo these with proper settings gave me pretty good battery life and performance with both kings and netarchy kernels.
If i had to choose one i personally like Evio best but thats mainly because Caulk is awesome and the davik is on the cache partition freeing up some of the space on the phone.

i've tried almost every ROM available (literally) and it boilded down between baked and evio. i'm still switching back and forth but am leaning towards evio as it has more tweaks (dalvik moved to sd, haptic feedback removed from dialer and lockscreen, ability to remove sense and htc lockscreen, awesome notification icons, clear htc lockscreen, debug icon removed, reboot/recover option when power button is long pressed...). calk also seems like he's on the ball more.
as far as battery, i think the kernels will help with that more than the ROM. i swore by baked #6 for battery life, but am test driving king's #6 CFS and i may have a new kernel i'll recommend for battery life. i was dropping about 5-7% per hour on average daily use with baked #6; i'm currently averaging a drop of 3-5% per hour with kings #6 CFS. if you're a benchmark guy, i'm also getting higher linpack/quadrant scores (at lower frequencies to boot) w/ kings.

I cannot find BS #6 anywhere. I have donated on the baked shack and never got access, so the only time I saw #6 was at install. I will try King 6 cfs right now. I have also heard this before.
I was on Fresh 3.3 and once I flashed NA 4.1.9, I kept losing my Sense homescreen option. Two fresh installs and same thing. I moved to BS 1.8....Hero and those guys removed all traces of BS from this forum and you can only get access to any of it from their site, which they drag their feet letting people in....Hence me looking to move on past BS.. and their BS.

hero did not pack up and leave... he was booted by xda (i'll reserve my opinions about the matter).
try sending them a message through their webpage. i had to do the same after a couple of days of no response to my donation.
how are you liking kings #6 cfs?

Booted from here...hmmmm, can't imagine why. I finally got CFS 6 flashed about 10pm and went to bed. I woke up at 7am @ 85%. It was like 98% when I hit the bed. Charging to full now and see how it does today.

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
Sent from my ADR6300 using XDA App

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)
Sent from my ADR6300 using Tapatalk

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 Battery Life ROM?

I've done some collection of ROMs that look the "best" to me, but not in terms of battery life; actual looks is what I liked about them.
Whether or not their battery lives are the best based on looks, I don't know, but I was wanting to see if there was one ROM in my collected list which most people found to be their favorite.
Here is my list:
OMFGB Latest Nightly
MIUI Latest
Virtuous Unity Latest
Pyramid3D Latest
TSM GingerBang Latest
RMK Ginger Sense Latest
TSMPoolParty Latest
Liquid Smooth
Of these, I've tried MIUI, Virtuous Unity, TSM GingerBang, RMK Ginger Sense, and TSMPoolParty. I liked Ginger Sense due to the fact that it is essentially a stock ROM but optimized, and I liked MIUI due to its simple complexity. I like the Sense look and feel, but senseless ROMs seem more efficient in regard to battery life to me.
So, what is your favorite among this list, and what can you recommend to me, knowing that I like a long battery life while still having the Sense look and feel?

Seems as if this is the incorrect section.
Could this thread be moved to Q&A, please?

My phone HTC HD2:
I used:
windows 6.5
Android
Windows 7
Ubuntu
I still Android ROM Desire Sense, it's slow but I like it. If be fast it be perfect.

So you used Windows on your phone? How did you go about doing that? What are the benefits?

Gingerbang 1.6 gave me the best battery life, with minimum usage, only voice calls and light web surfing, I got 4 days out of a full charge on the Mugen 1800mah cell. version 2.01 is very close but I had sense 3.0 patch running so the extra weight used up a little more juice. I would say GB 2.01 it's on par with Skyraider.

GingerBang 2.01 has all of the annoying Verizon bloatware that runs in the background disabled, correct? If not, how would you recommend either removing those apps, or disallowing them from running in the background?

yup, it has zero bloatware, you don't need to remove anything from it. I have tried every single one of the custom roms out there and the Gingerbang 2.01 is my only daily driver, with the sense 3.0 patch installed it looks similar to Skyraider (another hybrid rom I would run daily), but the Gingerbang feels much more responsive and snappier.

Using the HD2 you can gain root, and install many an OS on it. I think due to the windows mobile it ran on.

RMK Gingersense has the best battery life for me as a user.
My phone works. Without glitch. And it provides about 15 to 18 hours of battery life with decent business usage (calls, emails) and streaming radio (about 3 hours).
Why someone would need more then that I dont know - I mean, I charge my phone before bed so it is good to go the next day unless I am traveling.

I've had good luck with CM7 or OMFGB for battery life.
25 hours, and still 54 percent left

Wow, that's definitely very impressive. What settings did you have to change, or what do you do differently than stock, to get the battery to last for that long?

Nothing to much really in changes. I was using JD kernals 8-21-11 along with the smartass governor with CM7 nightly 56 when I took that screen shot. I also was using Incredicontrol with all the voltages dropped -25 from the stock JD voltage setting.
I hadn't been using the phone much that day though, so that really makes a lot of the difference.
Under moderate use I will go 24 hours on a charge pretty easily.
Edit,
Here's a capture from my Miui days.
This was with the Tiamat kernal, 1.1.2 I do believe, using the smartass governor (basically my default governor).
Since I was using the battery bar at the top of the screen I can't say what my exact percentage was that is left, but probably around 35-40 percent. This would be more of a normal usage for me.

I've been using GingerBang 2.01 for a while with excellent battery life. I'm usually down to ~30% left after 18 hours of moderate to heavy use.
ROM stability is very important to me, that's why I have stuck with this one. Long battery life is an added bonus.

Vanilla or Sense?

OMFGB for me
I've gone from CM7 nightlies to TSM Ginger sense to Gingerbang Vanilla to Mikrom's Inc2 HD to OMFGB.
OMFGB seems to be the most lean of them all, and therefore the fastest and best battery life. For me anyway.
I keep on hearing good things about Virtous Unity, I may try that one next.
I've used MIUI on my Inc1 before and it seems faster than CM7, so I might give that a go as well.

Seems as if you're on nearly the same exact path as I. Good to hear! I'm using HD right now. Is OMFGB a Sense based ROM, Vanilla, or AOSP? How much bloat is on it?

It's AOSP, which is vanilla. It's a custom ROM though, so there's tweaks and stuff added.

Alright, sounds reasonable. What all do you do to it from the original settings to get it to be most lean, as you claimed?

[Q] Rooted and poor battery life

As one of the primary allures to rooting is better battery life, I'd really love some help from the experts out there.
Background: Way back when the original Sprint Lovers ROM was supported and updated, I used that in conjunction with one of Netarchy's 4.2 kernels and all was glorious. I easily got 2 days on a single charge. After that ROM stopped being supported, I went with Myn's Warm 2.2 and ever since then, I've had mediocre battery life (get about a day on single charge). After Warm, I went to Synergy and finally, I ended up on Swagged Out Stock. I've tried various kernels...ChopSuey, Freedom...all to no avail. I hardly doubt I would have that bad of luck trying so many combos of ROMs and kernels, so I'm pretty certain I'm missing something.
I'll try to cover as many bases as possible to help troubleshoot, so if I miss anything please lmk:
- light to light-moderate user
- no live wallpaper
- usually max signal, maybe 10% is between 3-4 bars
- "Mobile Data Always On" unchecked, auto sync only on gmail, weather and news are manual syncs
- not the awake lock problem (21h since last charge, display is at 34%)
- have reflashed ROMs multiple times
- tried ChopSuey's kernel, lithid's aggressive and less kernels
- correctly recalibrated batt stats multiple times and anytime I flash a ROM/kernel
- 245Mhz-998Mhz, interactiveX, cfq scheduler
- in SystemPanel, nothing is taking up a significant amount of CPU space
- battery had light swelling so Sprint gave me a new sealed one a few days ago
Currently, this is what my software looks like:
Baseband: 2.15.00.0808
Kernel: 2.6.35.10-Freedom-v0.9+
SOS RC2.2
4.53.651.1
PRI 2.15_003
PRL 60681
I think that covers everything. I'm willing to sacrifice my first-born to get get back 2 days on a charge Thanks!

Get rid of Sense = more battery life.
Maybe try UltimateJuice from the market too.

You mean going to AOSP?
I understand AOSP ROMs in general have better life than Sense, but as Sprint Lovers was Sense wouldn't that be a moot point?

I never got to 2 days with battery life but if you want to stay with sense try freedom aggressive with clock speed 245-768 interactivex but AOSP does give much better battery life
Screen timeout =15 seconds
Gps off
3g off when not used
Brightness as low as you can having while still being able to see

Truth is, since GB came out, battery life is just not the same as Froyo. I, too, went 2+ days on the Froyo Sense ROMs I ran, with Netarchy SBC Kernels, but there is no SBC for Sense now, for one thing, and there newer versions of Android plus the Sense 3.x ports just use a lot more resources.

Sense in general is more of a battery hog than aosp. I can go 2 days plus on CM7.

Mikg plus aggressive is by far my fav against myns on sense. I easily doubled the life of myns. Slightly less than 2 days.

Hm, perhaps I spoke too soon. Maybe the new battery is helping or something because this is the best batt life I've seen since I flashed Warm 2.2 (did this around August or September of last year). Keep in mind that the batt I swapped out was somewhat swollen.
20h 7m since last charge and still @ 72%. If I'm not mistaken SOS comes with Freedom Less so I'm gonna try Aggressive and see how that pans out. I did not know that GB was that much more a resource hog than FroYo, so that was interesting to learn.
Keeping my fingers crossed -- thanks for the replies.

hmm glad to know its better...I had a question, i dont know if this is considered hijacking a thread or anything i'm sorry if it is, i couldnt seem to open my own thread lol...but its the same topic..
I rooted my friends evo and flashed it with koni elite 3 rom and netarchy toastmod 4.3.4 cms......the battery life was terrible even worse then when it wasnt rooted... so i thought maybe i didnt flash the kernel, so i went into recovery wiped davlic cache and cache and flashed the kernel...then i fixed permissions...but still terrible battery life..do you think itll get A LOT better after calibrating the battery? or that there is something else wrong with it?

Everbody and their mother says to delete battery stats. Lifehacker just linked an article a few days back that said that battery stats.bin delete is actually counterproductive.sense I stopped deleting it my battery is getting better and better..
Example; I have been tapatalking for about an hour now and it has been at the same bat level the whole time. Apparently it takes any a week or two to settle in the OS after the last erase.they also said the most likely reason to delete are new phone(as a baseline) or new battery. Lots of opinions but this tip is helping me...
