Best ROM for battery life?

I need my battery to last a full day with medium use. What is the best ROM/Kernel combination I should use?

i think fresh is supposed to be the best battery wise...but the negative is that you have to use its kernel. and its kernel doesnt allow overclocking/underclocking with apps such as setcpu and it also has the 30fps cap.
but if battery is what you need go for it. i also say go for it if you've never flashed a kernel to remove the 30fps. if you've never flashed a kernel to move the cap you wouldnt be able to tell the difference

I use Fresh 3.2 w/ netarch's Kernel w/ full 60fps unlock. I used my phone all day and still had 30% by 9pm starting 11am. Facetubing, gtalk, voice calls, internet, rss, time checking.

I've flashed a kernel before, but never knew if I was underclocked/overclocked. I flashed King 7 or whatever.

Most ROMs are built on the same HTC OTA releases (except for CM6, which has worse battery life than HTC OTA's); kernels are usually the thing that differentiates their battery life.
Fresh uses the leaked OTA stock kernel. You can probably flash this kernel to any regular OTA based rom.
...but the HTC Kernel has NOTHING on Backed Snacks Kernel #6. Go read the Baked Snacks thread thread. The battery life is literally ridiculous with Kernel #6.

Could I use the BSK #6 with Fresh?

Ok I went to the thread here:
http://forum.xda-developers.com/showthread.php?t=701685
And the link for Kernel 6 is not there, only 1-5

Dude, it might be the booze talking, but you got this thread on lock down. I couldn't have said it better than myself, what other dev has both a sick ROM and a sick Kernel like its nothing? I am still surprised dudes leaked his stuff because he gave all that stuff up no questions. And that is saying a lot because other dev's have better rom's with stock kernels. but the combo's and choices hero comes out with is what makes android android

You can underclock the kernel included in Fresh. And I do not see a point in OCing for 12%. The 1Ghz is plenty.

I downloaded Backed snacks, but there is no link for the kernel #6

Where do you download the Kernel #6 I can only download up to 5 as well.

Umm sorry my cm6 battery life is great I get avg 22-25 hours per charge with medium use far more than I have gotten with any sense rom besides baked snacks. Om testing the new flipz rom for a few days since i hear great things about the kernal
from the fade

In my opinion:
If you do not need 4G, CyanogenMod v6 with Snap kernel v7.5 would be your best bet.
If you do need or want 4G, Fresh EVO v3.2.0.0 would be your best bet.

Of all the sense roms i've tried, baked snacked seemed to have the best battery life of them all even beating out fresh 3.2 imo

Can someone point me into the direction to where I can flash something that will make SetCPu work with Fresh?

So Baked Snack Roms Nd Kernals Are the best battery life? I switched from his baked snacks 1.2.15 because it was missing vital features but how's the battery life on his latest 1.7 updated version is anyone using that rom nd kernal?

Leave your wifi on all day connected to wherever you are. It's the 3g data that uses much of the power. I keep my work and my job's wifi remembered and get 20 hrs on a charge with medium/heavy use on stock 2.2. If no access to wifi most of the day, this won't help you.

The 30 FPS limit and SetCPU are two different things. SetCPU will allow you to overclock/underclock your phone's CPU. The 30 FPS limit is a video limitation and will need a kernel to remove.
I'm currently running Baked Snack 1.7 and I believe his stock kernel. I get about 14-15 hours with medium/heavy use.
Will be checking out kernel #6 later today.

Been out of the game for a while. Hoping for some discussion.

Hey guys running miui and haven't been keeping up on all the roms as of late.
Just wanted to see if anyone would like to recommend any new roms and kernels to try out.
Big things im looking for is speed,stability, and battery life. Also the look of the rom.
4g isn't as important but would be nice though battery life is really important though can't stress that enough.
And about kernals could someone explain the main differences totally lost on those. Like the havs and cuts and what not.
So any suggestions?

You're in the right place, people aren't just replying. But anyways...to the point
Sense rom- Mikfroyo, Myn's Warm 2.2, Azrael, Evio, are the talk from what I hear, all offer good battery life, and performance. All have 4g, as being a sense rom
AOSP- Personally I recommend CM7 Nightlies, android 2.3 You can also get the nightly version w/ wimax, based off build 24.
Kernels:
Savaged zen HAVS CFS+ works well for me giving me
HAVS- basically has a "preset" setcpu installed to regulate battery voltages
NO HAVS ^ none of that
SBC -superior battery charger, trickle charges your battery to get the "full 100%" can damage your battery, use at your own risk, and can cause the phone to lag
CFS- a fair scheduler to moderately disperse, well rounded
http://forum.xda-developers.com/showthread.php?t=894880 <- all ya need to know on kernels. I hope this helps.
Edit: http://mirror.munkibizness.com/ link to the savaged zen kernels. Also, give a kernel 2 or 3 days to "set in" for you phone to get used to it. Won't see a change right off the bat.

Thanks Alot Man, appreciate it.

Anytime man. Let me know if there's anything else I can help ya' with.

What version of MIUI are you on? I've been running MIUI since the beginning of November, I really can't use anything else. Nothing compares.

i'm running 1.1.28 and having alot of stability and force close problems hang ups freezes etc. it's really annoying and while i love the look, which is basically prettier iphone with widgets. wish folders were as easy as ios though a little annoying on here so i haven't organized my apps since i had to reinstall all my apps.
i'm really just looking for the best battery life first, then stability/speed. and i'm so low on time to test stuff. working for a startup that just got funded so we are in overdrive trying to do the work of 20 odd people with just 4 or 5

Did you run calk's format all script before flashing? I'm on 1.1.28 as well and it has been more stable for me than any ROM i've ever tried. Not a single force close or reboot, it doesn't hang, and my battery can last two full days. Also have you tried any different kernels? For folders I use SiMi Folder Widget, it's very easy to organize and it looks great.

yes i did interested in your setup it's nice what do you use

Well like I said, I'm on MIUI 1.1.28 with the kernel that it comes with, LauncherPro Plus, SiMi Folder and SiMi Clock. All of the icons are part of DreamLyfe icon packs. I use Agenda Widget and System info Widget on one page and then Beautiful Weather and Pandora widgets on the other. That's pretty much it, I like to keep things nice an simple.

Why Should I Flash A Rom?

Right now, I have Chris' stock pulled kernel with CWM. I've flashed the No-CIQ mod. I use Go Launcher EX, which has a lot of themes(using Glass for now). Tegrak lets me overclock at 1.4GHZ stable, Quadrant scores around 3900-4000. Use Lcd resolution for a density of 200. Titanium lets me freeze apps like Mediahub. Since installing the kernel over 1 month ago, I've had zero LOS. My battery goes 12 hours, with light use, and still 40-50% left. So my question is, what would I gain by installing a rom that I don't have already?

I'd leave it be. Sounds like you're doing just fine.

Of u like something a rom offers then go for it, otherwise leave it be.
I personally like stock deodexed and rooted.

I personally flashed a rom because I wanted battery Percentage and I also liked the Battery savings some of them offer. Such as Calkulins Rom, which has the Cpu script that undervolts as the battery goes down. All in all it depends on what you like.

You can see from my sig that I like flashing roms. I'm just finding it hard to justify in this case. My phone pretty much is rocking the way I have it set up now, stable as anything. I'm sure at some point I'll flash just for the hell of it, when I need to kill some time.

If you are happy with the phone as is, then let it be. My biggest reason for loading ROMs is for the MODs. Back in my EVO 4G days it was also about getting new versions of Sense that that kinda thing.

I love the miui battery bar

Biggest thing for me was the Lockscreen customization (running Starburst 1.9)...being able to unlock phone directly to an app (I use the camera...many fewer missed opportunities with my kids now) is pretty much priceless.

Widgetlocker gives the same options.

I have been losing a lot of sleep because of this. I just want some recommendations and opinions!
Running Jugg 4.1
Tried both Faux (007b5) and Bullet 2.9b.
Which one is better to use if I want good battery life but good performance as well.
I know in faux's, its been OC'd for the 2D and 3D...does that mean Bullet is not?
I just need to know which kernel works the best with Jugg...thanks!!!!!!!

prob bullet works best with jugger, but i do recomend faux, thats what i use and i love it! amazing battery too

thanks for the quick response. btw, when you say works best what do you exactly mean? and if thats the case, how come you recommend faux?
so sorry for being so specific, but im going through that phase of trying to settle in with a kernel/rom but i keep getting mix feelings!!
thanks in advance

lol its all good i understand, well my current setup is gingersnap, and it has faux and im in love! silky smooth,i had juggernaut before that with bullet and it was nice also, but i once flashed faux and battery was not the greatest with jugger, later on i found out it was cuz it was OC to 1.7, but give faux a shot it wont disappoint
ive tested every rom and kernel out there faux with gingersnap is my fav by [email protected]

You lost a lot of sleep because of this?...
Sent from my SGH-T989 using XDA App

every phone operate differently.. but generally juggernauts battery life doesn't compare to the asop roms for obvious reasons... but it's not that big of a difference... about 30 mins to 1hr more on screen time (if using adjusted settings) i personally use dewizzed... their rom is great for battery life..
here's two setup for dewizzed..
dewizzed + faux + gideon script (no CPU controller app// set cpu, systemtuner etc.)
dewizzed + synergy (not sure but apparently stock synergy is fine, but a lot of people adjust values with system tuner.. check the thread for synergy)

Bombaridier is the rom to go
If you really want great battery life , there is no better rom out there than bombardier 3.0 or 3.5
I don't OC or UV or anything and I always got around 18-20 hours a day.
Give it a try

Best/recomended MIUI rom?

Hello all.
I've been out the loop for a while now, still got stock sense on my DZ but have recently become very interested in MIUI roms. I have a few quick questions I hope someone can answer as after reading the various roms etc I'm a bit confused.
1. How well do MIUI roms work with the hardware keyboard? I'm seeing a few threads saying it isn't totally supported. This is a deal breaker for me really, can anyone clarify?
2. Which MIUI rom? I see there is an official one, but also others similar to official eg MIUIandroid, any particular 'best' version?
3. How is the battery life compared to sense? Does anyone have any current draw figures for screen off etc, my sense draws around 32mA screen off.
4. I assume they come with overclockable kernels, if so, is OC beater or whatever it's called still the best to use?
I'm interested to hear from MIUI users, sell it to me.

1. I've had no problems while using the keyboard with MIUI, it seems to work the same way as before. I have heard some people say that their backlights don't work but mine do. However, landscape is not supported on the homescreen but it is everywhere else.
2. I use the official english supported rom for Desire Z/G2, you can get it from ROM Manager or the MIUI website. I'm not sure about the best one because I've only used the official one.
I don't know about 3 and 4 but I do enjoy using MIUI. It was the first rom I used after I rooted my phone. I used to want sense but because of emoji support and themes I probably won't use another. I do recommend it as I have not been disappointed.

Thanks for replying.
Instead of exact current figures, maybe you could say what your typical daily use is like and what your battery level is at the end of the day?

I've tried miui us and miui android. Both are good and can tell any difference in look feel or performance. Also tried a couple of the miui v4 roms in the dev section. They are really good and give a snappier feel to the miui environment.
V4 is possibly better with battery but marginal. Compared to the stock rom I came from, battery is much improved. No figures I'm afraid as my days vary greatly. Camera is an issue on all ICS roms on the dz/g2 so decide if that's a problem or not.
Enjoy.

Thanks for that.
I'm gonna flash the 'official' miuiAndroid tonight I think, need the camera so the ICS is a no go for now.
As long as battery is noticeably better than stock sense then I'll be happy.

good luck and enjoy. Give it a couple of charge cycles with the CPU adjusted you should see a significant improvement.
I generally run 900mhz Max with interactive governor.

i definitely recommend the MIUIandroid version, the translation is far more complete. Miui.us just has faster servers! If you send/receive a bunch of picture messages, I suggest you download my modified Mms.apk from the link in my signature, more info is in that thread.
I've been using MIUI.au v4 for the last few days. pictures are slightly annoying, but if you take two or three, you usually get a good one, but the pictures do have to be taken in landscape.

Well I have been running it for the day and I have to say that I love it! Much better than sense, seems really stable and I love the customisation.
I was going to ask about that mms thing, I'll check the thread out.
As for the battery, it has run down quite quick today but I've been playing with it a lot and expect to need to have a few charge cycles till it settles.
One question though, does the OC/OVbeater overclocking thing work with this rom/kernel or should I stick with set cpu?

Just to give you an answer, I don't know. But it's an AOSP kernel so... it should!

Have you flashed the bulletproof addon? It adds the Vituous OC daemon as well as OC/UV Beater. From there you can operate as intended and should probably have no issues. Personally I've never been able to OC over 1,3GHz on any MIUI ROM, may be the Tiamat kernel for me though...Anyway the highest I'd go on MIUI would be just barely 1,3-1,4GHz! Practically you wouldn't be needing more than 1,2GHz for heavier apps but considering this is MIUI and is a bit heavier, 1,3GHz will cater your needs.
Otherwise, OC/UV Beater will work but it will be limited to just Normal configuration, since the Virtuous OC daemon (which I presume you use?) is not cooked in, hence it can not be configured. You also can't undervolt because viper uv is also not included. If you're not interested in flashing Bulletproof then I'd stick with either SetCPU or even CPU Tuner (switched to this over from SetCPU and liking the fact it has more extensive configuration, as well as less battery drain). You can find CPU Tuner in the market, if you're interested.
Also, battery life wasn't half as bad actually. I find the MIUI Launcher to be a bit heavy and more resource consuming for my use. You can use Go Launcher or ADW if you want though.

Take a look at the bulletproof add on pack. It includes some nice tweaks, one being a kernel that supports OCing.

I will like to second that! Im running a MIUI V4 port by ajhavery and lenny_kano (MIUI_Au 4.0.3 base 2.3.2) and it is working very well. Except my battery life is not as good as the official MIUI ROMS. BTW Angel Camera from the market works perfectly on this ROM with no glitches.

Oh so you can use the bulletproof add on with any miui rom then?
I'm using setcpu just now but I may try cpu tuner. I tend not to overclock to be honest, I'm more interested in underclocking when screen is off etc but I may try 900MHz or 1GHz, it's running very smooth at 800MHz though.

1. Bulletproof addon is for ANY 2.3 based miui. NOT miui v4.
2. The chip in dz/g2 is designed to run at 1ghz. Htc just UCed it to save on juice and market it as a lower spec (that's how I understood it anyway). I find at 800 it just feels a touch laggy. That extra 100 takes the edge off.
Sent from my HTC Vision using xda premium

Does installing bulletproof clear any data at all?
Is it flashed from recovery?

Shouldn't clear anything. I say shouldn't as you can never guarantee it. I've never had any issues. Always a good idea to clear cache and dalvik when flashing anything. And yes, its flashed in recovery.

So I flashed this at the weekend and so far all is well.
Though I must admit, I'm not noticing the battery gains I was hoping for, a minimal boost is all. It does kinda seem that it uses more with the screen on than it used to, some comparison figures for those interested, taken using battery monitor widget.
Screen Off
Stock Sense: 31-34mA current draw
MIUI: 28mA Current Draw
Screen On (taken as sitting at homescreen doing nothing)
Stock Sense: 147-190mA
MIUI: 137-230mA
It's probably still calibrating and I never wiped the battery stats. Would there be a benefit in doing so?
Also, I have noticed that when charging, the light goes green when charge is only around 90% done, any news on this?

The light goes green once the battery is > 90%, this is more or less intended behaviour.
There had been a recent announcement by a Google employee that wiping the battery stats has no visible battery life improvement. All it does is wipe the statistics file that shows you what uses your battery. What you can merely do is run the battery down to 20~% (wouldn't go below that as the failsafe might go off) and then back to 100% for 3-4 times, so that the Battery Meter can become more accurate. From there it is ideal to run it down to 20-30% twice every month in order to keep the battery health in good shape.
MIUI was merely created to be iPhone-ish, cool looking, and very user friendly. It looks awesome, inarguably, but battery life isn't it's strong point. I wouldn't be surprised if it draw more than Sense itself, too. ROM's that have the best battery life are barebones. These have a lot of features suppressed in order to save up in RAM as well as battery consumption. There's also little customizing you can do to them.
However, if you want a good battery life ROM that does not cost you anything in features, you should try Tsubus' ILWT CM7 ROM. It is a CyanogenMod 7 based ROM, that has been fine tuned for speed and battery life alike. I've been a user for a long time and the phones takes me easily through a day with plenty of juice left (about 40-50%). You will have to go through the above meter calibration process again.

Yeah I know and don't get me wrong, MIUI gets me through a day no problem, maybe I was just being a bit too hopeful.
Have to say though that I have fallen in love with MIUI, I can't imagine using another rom now.

well if you are looking to use the bulletproof addon then i made a rom myself with some mods included in it... you can check it out from the link in my signature...
