best rom for batterylife?

hi, i have a thunderbolt and the batterylife sucks. any suggestions for a rom and kernal for the best batterylife? thanks

IMHO there are no black and white answers to this. It depends on how you use your device - more for voice/text or more for data, where you are in relation to the towers and how often you are moving between 4G and 3G.
The one bit I will attest to through experience is that the Gingerbread Sense ROMs chewed through battery a lot more than the Froyo ROMs. (Except Cyanogen Mod 7 but there are radio issues with that. Ones I have learned to tolorate as it is my DD.)

Regardless of rom, you will get max battery with imoseyon's kernel, battsaver mode, 1ghz max + whatever min your phone can handle. Froyo roms get marginally better battery than GB roms. I have not tried cm7 but I have read more than one person suggest it gets less than Froyo or GB.

Froyo 1.66 Stock (plainjanev3 I think is the rooted version). Guaranteed best battery life among the whole bunch. with moderate use, you can go a full day.

Never had any problems with any of the BAMF ROMs

I am going to build a solar powered charger. All supplies bought from Radioshack for around $30. This way, I can carry a charger with me anywhere I go.
However, I am running gingertheory, and battery life has been pretty good. Can go all day at work and lose about 60% with heavy use.

I'm going to second this one, The gingersense roms total kill my battery, but cm7 sips it slower than any other rom in my experience. It's totally functional for me, with the exception that I can't receive vcards in MMS, and the MMS issues are well known. It's my longest running DD currently.

Inspire Question

What I am wondering and before you attack me I did research this and couldn't find anything specific to the Inspire. I want to know generally what is a good speed to underclock the inspire to achieve maximum batter and before you say every device is different I'm asking for a general idea not a specific one. Also do you think that overclocking has a big impact on batter I am overclocking right now at 1.3 ghz do you think that I'll notice a difference. And I know I have to test it myself but I just want others opinion on it.

I have the same question.

FWIW, I run the OnDemand Governor and underclock at 883200 (245000 min) and don't notice a slowdown in any apps I run except angry birds (I ramp it up to 1.2 to play that). I haven't run any benchmarks or anything to see how it might improve the battery, since I really don't need to worry about it. It goes on the charger every night and I've never seen it below 50% when I plug it in.
I've been running a relatively stock DesireHD Gingerbread ROM based on the Asian WWE GB (2.37.707.3) but as of yesterday, I've been running one based on the telus GB released a few days ago (2.43.661.1). My kernel is custom based on stock HTC source for the 2.6.35.10 with OC/UV support added as hacked from the LeeDroid kernel tree. My source is here:

I'm running at my rom's default (1017mhz). Instead of underclocking, I use the conservative governor. Battery life is good, but I also haven't noticed a battery drain when overclocking (I've been up to 1228mhz). I didn't test/run it for an extended period of time (1 day), but I only noticed a slight bump in performance.
I've heard of people on my rom (GingerBeast), clocking down to 768mhz without noticeable slowdown. As you stated, it just depends on the rom.

I have my phone set at:
Max: 768000
Min: 230000
This works for me in literally all the situations.

Thank you its like they either yell at you to search or they give you all devices are different you have to try it. I'm not looking for a definitive answer I just wanted an idea of what has worked for them. Seriously this forum has some rude people exspecially that Scott guy hasn't helped me once just tells me to search I said I searched and he says its on google but when I bring up the page nothing. This forum would be 1000x better if people didn't have a stick up their asses everytime someone asked a question.

I hope my response wasn't considered rude, but the question really is too vague to answer. If there were some magic combination of OC/UV that worked for everyone, everyone would be using it.
They say that if you ask five New Yorkers their stance on an issue, you'll get six different opinions. Similarly, five smart phone users probably have six different opinions about the best setup for their device and none will be applicable to your situation.

Yea but I wasn't asking for the perfect combination out just wanted to know what others use to get an idea of what I should set it at but clearly you don't get that
even though I've said it three times

Overclocking Nexus S with Oxygen

Hello all,
I just flashed the latest Oxygen on my i9023. I noticed some good improvement when I set the max clock speed to 1200 or even 1400. Thing is, I want to use this phone for atleast the next 1.5 years and so don't want to wear the processor or something.
I have not suffered any problems or reboots even while running at 1400. Any advice on the safety of overclocking? Also, how do I know if this is overvolted?
Thanks

On the overvolting/undervolting thing, you might wanna give proton voltage control a try. it's developed by xda member jonathon grigg and you can find it on the market. From the app you can see what the stock values are as well as over/undervolt yourself.
can't help you with the overclocking bit though sorry

I wouldn't worry to much unless the phone gets extremely hot or shuts down alot.

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.

woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw

Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.

Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

Battery/Kernel Dilema Advice/assitance

Well the thing is I don't know wich kernel to pair up with Hellfire Phoenix 2.1 so far it's what I have liked the most.
The stock kernel gives funky battery readings, I tried trinity ELP kernel but my phone doesn't last much as I'd like it to maybe I'm asking for too much from my g2x.
So what I would like to know is what kernel should I try for the best battery lifespan I am normally using 4g with pandora but while giving it this use and texting from time to time /checking facebook it doesn't last me through half a day I start using the phone from around 6-6:30 Am and by 1 pm my phone is at 20%. I give it breaks of around 1-3 hours in wich I disable data/ I also keep sync and wifi disabled.
Any advice would be greatly appreciated and +Thanks will be given to those that are helpful
PS.I have yet to try Eaglesblood 2.3.7 is it worth compared to hellfire ?

Using data on the phone like Pandora and Facebook for one hour will drop my battery about 15-20% on 4g so, 5 hours worth is about normal in my opinion if you plan on doing that all the time I suggest extra batteries or extended. You're simply asking too much IMO!

Thought so "( Either way With what Kernel could I get the best out of hellfire phoenix 2.1? Also I'm confused on some things like with the trinity ELP kernel it says it's 1.1ghz/UC does that mean it is undervolted while being overclocked by 100mhz (just making sure) also in CM settings I have the option of setting the cpu speed.. now if I set it lets sayy 750mhz is it also undervolting it?
I'm sure I don't need 1ghz for the use I give it most of the time I could just change it back when I
m in the mood for gaming or does this scale depending on the task?
Sorry for so many questions I'm still new to this and I want to be sure of everything

I'd say either the kernel you have now or Faux UV version... look up the thread that shows "how to undervolt" (or something close) and go that route if you truly want to get the best battery life (I don't undervolt as I get the battery I need for my daily activities.)

So Faux123 Kernels are the ones people use the most for what I've seen.
I'm not sure wich faux kernel I have It says 2.6.32.56 CM7 Faux123-049, I checked the thread and latest is 0.48 soo I'm a bit lost there
I've also seen some people say they prefer the trinity kernel because it was released later.
I've tried both the stock Faux that comes with hellfire and the trinity I do not see any difference whatsoever in battery life or stability ( trinity does score significantly higher on benchmarks)

I could careless about benchmarks haven't ran one since I got this phone and oc'ed it to 1.5 to see what would happen... other wise they are just options some of our phones can't handle certain kernels... play with them and see which you like more. My only advice is faux cm version lol ds causes the funky readings.

faux 049b5 is for ICS roms, 048 is for GB roms. Don't mix them up or rom won't boot.
Doing anything on 4g will drain your battery much faster. If you can switch to 2g/3g networks while not using data, it can save a lot of battery power. Try Juicedefender ultimate also. It helps in toggling/switching options for you.
Every phone is different plus everyonez preferences/usage are unique. Best bet is to try both for a week or so and then decide for yourself.

Anyways I flashed the 1.1ghz/UV Faux it's working with no problems so far I'll stick with this unless it gives me any kind of problem. I will look forward on getting me one of those 3500mah batteries Price/performance they seem worth it though the phone would be fat haha but w.e I like using my data without worrying of low battery through the day.
This is unrelated but just throwing it out there. The Camera ICS+ works great I see an improvement in picture quality compared to the stock and the interface is lovely

Have you not been reading anything on any of these forum's?
I know your new to this ( as you stated) but you keep asking questions that can easily be answered by just searching and reading the forums,
i keep trying to help you by (doing the searching for you) but you just keep asking the same questions over and over,
you have like at least three different forums were you keep asking about kernal's ( and in several of them i have giving you links that should answer just about every thing you need to know about kernals) if you would actually just read them.
Im not trying to flame you... its just that you keep making new threads asking pretty much the same stuff, we can tell if someone is taking the easy way out and just saying that "they searched and didn't find any thing"
the people on here that would actually help you out, know better.
because they read the forums just about every day so we know how many forums that are out their, on subjects such as kernals, like the 3 threads you started asking about them.
so again read and most of your questions will be answerd...

The more you read the more you would find out that everyone has different experiences with kernels. Try them out and figure it out on your own... if you have thread already about a kernel or a specific rom to choose stick to that thread and don't make a new one, as it just causes clutter for people that do use the search function, as when they search for something like "which kernel" they get

ELP voltages are probably too low for you, thus actually causing higher drain. Try the T15 and under volt until you find your sweet spot
