[Official][MODS LOOK!] Best kernel/ROM combinations for increased battery life!

When I first joined this forum, I was very impressed with how responsive the XDA community was to answer my questions. I have gained loads of valuable information that has helped me along my way with my EVO. I had one goal in mind; I wanted to customize and modify to increase my battery life. the Q and A forum was the first one that I turned to. I would instinctively try searching for things such as "best battery saving kernels" or "Which rom will provide me with the best battery life" and etc. Of course there are hundreds of threads with people asking these types of questions, the only problem is that they are outdated! I have only been active in this forum for a better part of 2 weeks and it seems like there is a new or beta out every other day!
Developers are quicker than ever releasing new kernels and roms so it makes it difficult to get a defined answer! I figured that the best solution to this would be to have a stickied thread with the community posting there results through testing or just opinion in general, that way it will help stop all of the "best rom" or "best kernel" threads. It would be a great resource to not only people that are new to the forum but for those looking to stay up to date with the best of the best.
Now onto the purpose of this thread.
I realize that everyones phone is different. And that what is best for one phone, may not be best for another phone.
Still I think that a generalization would be very helpful when trying to decide what's best.
Here goes:
Kernel Testing Reports: AOSP and Non AOSP Kernels here: http://home.comcast.net/~ttechnology/htc.html(Not my work, all credit goes to Skyler.
What are your favorite kernel/rom combinations for saving battery life?
Feel free to report your testing results and attach screenshots of juice plotter and etc!
Hopefully the whole XDA community can help keep this updated for reference at any point in time!
With all that said, hopefully I will catch a mods attention and have a chance of this getting stickied.

11/2/2010Myn's 2.2 with Baked Kernel #6
This was my first day testing this combination with moderate to heavy usage. Battery life was not very good for me. I will be trying this again tomorrow to give my phone time to adjust better. Screenshot attached.

Bump...report your kernel/rom history and what has worked best for you!

Well I thought it was a good idea anyways

I used it sparingly. Some twidroid, some browser, some freecell, a call or two and EVAC(great game). Yea its launcher pro. I grey'ed out everything like the status bar and notification bar. Made it gingerbread like. Or what rumors say gingerbread will look like.....

fresh 3.4, nets 4.2 bfs agressive , been getting 90ma screen off and around 200ma screen on.
i'm really interested to see other battery draw compared to mine.

Very cool, hopefully more people will become involved with this thread and it can stay up to date. Thanks for you input!

i just got 1d 6hrs out of my evo.
I would categorize my usage as moderate (facebook, texting, phone calls, some game playing, maps, music playing)
Fresh 3.2 w/ launcherpro mem set to high (sense removed)
Stock Kernal 2.6.32.15-g3a8614e
Underclocked w/ SetCPU (screen off 245/screen on 652 max)
Autokiller set to "Extreme"
4g turned off most part of day since i dont get a signal at work.
Turned airplane mode on the second night (went to bed with 6% left...woke up with 6% haha).
Forgot to add
I have always on mobile turned off and background data disabled (only thing noticed with these settings is that 3G wakes up a lil slower when turning on screen and you cannot go to the market unless you turn background data which is okay for me because i pretty much have all the apps i want.)

Sounds like Fresh 3.2 stock is very good battery life. I have heard this before just never tried it out. 30 hours is a long time on a single charge with moderate usage.

I've heard the same thing, that Froyo does a great job of managing background apps and etc. However, when I look in my systempanel app I still see a lot of background stuff running that I didn't even know about, and a ton of apps running in the background.

I don't get many apps running wild in the background for me. Um...

I'm pretty new to all this and just recently started trying a non-stock setup and it has been giving me really nice battery results. I don't have have any graphs or screen shots, but the first time i tried to fully drain it on purpose had me laughing hysterically. I was running 100% brightness, wifi, gps, bluetooth and pandora. The darn thing ran for like 5-6 hours straight. I couldn't believe it. seemed ridiculous.
took it to disney yesterday on a full charge. made a handfull of calls and a bunch of texts. checked the weather and a few other misc. things.
came home with 80-75 battery life. was very impressed.
i never got this kind of performance on stock.
Here's my setup:
Myn's TwoPointTwo RLS2

Very nice to see others having success with the battery tweak! It is still my primary go-to for when I know I count on good battery life. Did you happen to check out my guide in my signature?

well from what i read autokiller is not like a "task killer". It modifies/improves how android kills processes if that makes any sense.
been working for me...

We need to be using more descriptive scripts/apps to be comparing such.
For example my ROM is heavily stripped down/modded.
Also consider that everyone should be clearing caches and allowing them to rebuild before testing.
Not to mention anyone who has a flush active (use "top -m 5 -n 1" to see) will have much lower performance.

How long do think your phone needs to rebuild a clean cache? A couple days or so?

[Q] Rom with the best battery life

As the title says.
I am interested in your opinions.
Which one is the best for battery life?
Thanx

There isn't one in particular as it depends on usage and the apps installed

Fresh roms and the cyanogen 6.1
Sent from my PC36100 using XDA App

Hi folks,
Just a thought,
Is there a clear view on where real battery drain occurs, by this I mean (for example):
o Radio;
o Kernel;
o Keep Alive Apps / General Health Apps / Background Apps.
Incompatibility between components, e.g. Radio and ROM fight over timing or API issues or .....
Like dzontra11 I'm interesterested in having a phone (good battery life like my old 6210 or 6310i) and occasional Game Use with Internet Browsing (including Gmail sync). WIFI in the flat (90%) and a little 3G around and about.
So I guess I'm asking which combos work best for general use and still be usable. My phone (won't say which radio/ROM combo ATM) informed me earlier that the battery was low, which it was. The sodding phone turned off 2 secs later @ 17%.
In my past life I looked at a lot of system performance issues (usually the classic CPU, I/O & Memory). So I'm guessing where are the current thoughts on this are by people that know in detail.
Regards
Colin

Best I have had to date is DeFroST (all versions seem to be close in usage) with juice ultimate looking after things, gets me almost 2 days with moderate usage.

[Q] Desire eating battery more than usual

Currently I am using this RomHere
(I was forced to because when I flashed an update to the Superuser app, it worked fine, but when I turned it off for the night, the phone wouldn't get past the 'HTC' startup screen, and trying to factory reset/ flash an RUU didn't work)
When I was using stock Froyo, the battery life was moderate. It *normally* used to go down around 1% every 2 hours or so in idle. Since I've flashed this new rom, it seems to go down 1% every 30 minutes instead, Even with the screen off and the phone fully off, the battery drains horribly quickly.
Any solutions?

That is the rome, dude. Sense2.1+3.0 drains more battery than stock froyo. That's the price. And 2%/h is not bad for sense roms.

It's that bad? Is it the whole of Sense which drains it, or more specific apps/widgets?

No, imho it's not.
Sense and the inherent runnig apps/widgets.
But with setcpu and a screen off profile (245 min 245 max @ondemand governor) you can really improve your battery standby power. You can download this paid app here for free, because you are an xda user:

Out of interest, does it damage the phone if it's underclocked? I'm just worried that I'll burn the CPU out f it is underclocked and clocked back to stock if I frequently turn the screen for mundane tasks like checking the time.

I recently flashed to that ROM too - and I agree, battery power seems to be draining slightly more quickly than what it was originally (it could be because I'm playing around with settings and exploring new features). But probably not so much more that I'd be worried... left it charging overnight, and seems like I will be able to get a full day of normal use out of it (currently ~65% left and ~3hrs till i get back home).
Maybe double check your sync settings? possibly they've reverted back to sync-ing more often?
Otherwise, I guess you can go for a lighter ROM (i believe cyanogenmod will use less battery since it doesn't have Sense UI).

Actually, the battery does go down faster on InsertCoin 1.0.8 if you use all the Sense 3.0 goodies for example the weather lock screens, weather widgets, and the windmill-thing live wallpaper, which also changes its apperance with the weather.
Those literally suck the battery out, 40% only in 3-4 hours.
I have tried to deactivate those and the battery live is back to normal.
...the only problem is...those goodies will make your Desire super duper beautiful...it was for me a very hard choice to turn those off

Dunno about that but nothing bad has happened by me and I have been using setcpu for more than 8 months.
I use set cpu to speed up my Desire a bit, I set it to 128 - 1136 with smartass governor. (carefull by setting higher frequencies)
tips for battery saving:
- turn off sense sync and any unwanted syncs
- reduce sync intervals.
- turn off automatic brightness control, and set it as low as possible but keeping it still visible.
- use smartass or interactive govenor on setcpu.
- turn the internet connection off if you are on low signal strength.

Yeah, the more animation, the more battery use. I think the only one I use now is the weather widget... though I actually prefer the old sense 'simple' animation, not a fan of the sense 3.0 videos... got to find a way to revert to the old one! (using clock lock screen.... prob chews up bit more battery than plain wallpaper, but oh so pretty!)

[Q] Why is Battery draining so fast on my Samsung Galaxy W (GT-I8150)?

I have upgraded my Galaxy W to Jelly Bean using Custom Room (4.2.2) Cyanogenmod 10.1 alpha 2. maybe later alpha 3.
Everything runs well. but why my phone's battery drains so fast? and please help me HOW TO SOLVE IT AND MAKE IT LAST LONG TIME???
THANKS VERY MUCH....

Backup your apps, factory reset your phone. If battery drain problem persists, install Greenify or deep Sleep battery saver from Google Play to better manage battery resources.

when you just flashed the battery will definitely be shorter. Let it recharge for a few cycles before determining whether its good or bad battery life. Keep in mind however that even at full potential, the battery will not last for more than 2 days even at light usage.
if battery life is more important to you compared to "the newest OS" and whatever extra features it brings with it, then I highly recommend installing acro's CM9 RC2 (yes it is ICS) as the 2.x.x kernel is far better at battery life than 3.x.x (i'm currently testing it and I can already feel the difference! I believe I can reach 2.5 days at modest usage but I will have to update you on that after my first few discharge cycle for battery to reach potential after flashing new rom). I do, however notice a few annoyances with RC2 (not sure if its really the ROM, or the custom kernel i'm using, or Nova Launcher is to be blamed), so if it continues to bug me I may just switch back out to latest ICS =p.
If keeping with the latest JB is important for u, best thing you could do is download a custom kernel for it that supports UV(undervolting), then get IncrediControl and tune down your UV based on some voltage tables you can find in FAQ. This alone won't bring you a HUGE improvement in battery life but its definitely an observable difference. On top of UV, try to UC(underclock) your CPU to 1GHz. Most daily functions, apps and games (depending on how intensive it is) will work perfectly smooth even at 1GHz. IMO, the most important point of UCing is you will notice a very significant difference in the heat of your battery (ie backcover of your phone). Heat is generally bad for the battery (shorter life + faster draining) so UC is definitely a good thing to do =). Of course, on top of all those, get greenify and wakelock detector(WLD) from market to control your not-so-frequently-used apps. Use WLD to track down what is keeping your phone awake (hence drain more battery) and use greenify to hibernate all the not-so-frequently-used apps you have (example of things you DON'T want to greenify: whatsapp and gmail as you don't want to kill these 2 programs when you lock your screen. You want to continue receiving whatsapp messages and gmail when you locked your screen right? XD! Examples of things you SHOULD greenify: games, music player. Maybe some of the games or other apps may keep a background service active, secretly using your battery even though the last time you used it was 2 days ago!)
Finally, if your wonder is about 1-1.5 years old, chances are your battery is already bloated (perhaps you can feel your battery through the backcover of your phone even!) A bloated battery is a dangerous and short-capacity battery. Even with the best rom you may only push through a day from 100-0%. If your battery still looks fine but your phone is nearing its birthday, go ahead and do some online shopping (ebay or local equivalent, like malaysia we have Lelong.com.my) and get a battery for your phone. Its usually much cheaper than buying from telephone shops.
EDIT: Adding on to all of that, choosing a good governor+i/o scheduler combo is important as well. If our phone is similar with the S+, smartassv2+sio(i've used this, its quite smooth and battery is good) OR OnDemand+noop is thought to be very good in terms of battery life and responsiveness. Lulzactive is also very good but its not so easy to tune it so i usually would stay away from it. Do bear in mind that although the former 2 combo is good, it still highly depends on how you use your phone so there will not be a universally best governor+io combo. Both of those suggested by me are supposingly best in responsiveness as well as deepsleep battery conserving (only if the assumption that our roms work the same as the roms tested in S+, which MAY NOT be true).
TL;DR? try smartassv2+sio (u may change this using IncrediControl, get from playstore). Then if you are not satisfied with your current performance/battery life, you may continue experimenting by changing governor and i/o scheduler one at a time. If you are doing the testing, make sure to have some way to record your tests if not you will 100% be deceived by placebo!(with actual numbers you will clearly see whether your feeling is placebo or if there really is an improvement)

I'm having some seeeeerious battery issues with alpha3. With just 15 minutes screen usage in a day, battery settings says my screen used up more than 20% of the battery! This just for consulting the time and the weather.

that 20% is not actually the 20% of the battery juice. It is 20% of whatever amount of battery is drained due to the display being ON. Like if your battery is used from 100% to 90%, then only 2% is used by the display.
I am not sure if I could explain what I mean.
EDIT: Hmmm maybe I misunderstood what you said... If that is the case, disregard.
And also my galaxy W will use all of its battery charge when the display is constantly ON for about 3-5 hours.

Actually, I've figured out what it was. It was Google Now. Chewing away at the battery without saying a word anywhere in the battery screen. I am now back to my old 3 days battery.

you need to install cpu spay from google play and you need look deep sleep time.

this reaction is typical if your coming from a stock or at least cm9.
there has been a lot of arguments about battery life of cm10 and above.
in my opinion, there really is a difference, i mean cm10+ drains battery faster.
and the reason being is of course the features there is in cm10++.
if you're after battery life, stay with stock or cm9 (for now).
but if you feel like your in with cm10+ and you don't want to go back like me, then may want to try these tricks:
1) using Titanium Backup, freeze the apps that you don't really use.
- in my phone i froze pico tts, voice search, talk back, etc. (i even froze google search )
2) i use an app called "autostarts", it can disable auto starting of app including those of the system.
- in my phone, i disabled google maps in every activity. ex. after startup, connectivity changed, wifi connected, widget updating
3) disable system settings which also contribute to battery draining.
- disable location service when your not using it
- disable automatic backup/restore
- disable haptic feedback
- disable autosync
- disable the top battery drainers when not in use (wifi, mobile data, gps, bluetooth)
- and many more just explore
4) do not use so many widgets (my home screen has 0 widget)
5) do not use live wallpaper
6) charge only using the original charger, not from other phone/brand, not from a usb port
- the best way to charge is to avoid using the phone until it's fully charged
7) finally, install only apps that you really need. just keep a backup of your not so often used apps and install only when you need them
If you think about it, everything i wrote above contradicts with the original concept of Android.
But that's life, sometimes you have to trade something in order to achieve another.
Our phone was baked as Gingerbread, now we want to make it taste like Jellybean.
We have all the ingredients, but we don't have a jelly bean pan to make the candy molds.
So we improvise, we work around, we do some shortcuts, we make alternatives, certainly it will cost something.

I'm having some seeeeerious battery issues with alpha3. With just 15 minutes screen usage in a day, battery settings says my screen used up more than 20% of the battery! This just for consulting the time and the weather.

3 days with Zl... is this normal?

Hi everybody
I had bought a Xperia Zl 3 days ago and I love it (I used a Xperia P before) now I have 3 point that I don't like of it
1. Sony UI (is not ugly as hell but it can be better)
2. Battery (it goes very fast for me)
3. Sony update service (they are so slow releasing upgrades)
So, the problem is the second one, is normal this phone eats so much battery?.. But there's something else, the download is not normal for me, the phone when is full charged and I disconnect it begins to down the battery in pair numbers I could say, from 100-98 from 96-94 but really fast, just making calls?
Then, when 60 percent of battery arrives the download begin to slow the speed I mean the battery is during more....?
Is this normal? What do you think? Sorry for my bad English and long text...
Cheers

Welcome.
1. Sony UI:
You can install the launcher / theme of your choice. Many people go (in Google Play) to:
Nova Launcher,
ADW Launcher,
Apex Launcher,
Holo Launcher,
GO Launcher EX,
MiHome,
Regina Launcher,
Smart Launcher,
SPB Launcher,
Next Launcher,
etc,
only to return, months latter, to the original Sony launcher (this is my case).
2. Battery:
Please remember the power management options (stamina, low battery mode), and also turn off GPS, bluetooth and data transfer unless you really need it (Wifi usually consume less power than 3G). If you want more, there are some really good threads in XDA about how your battery could last longer.
3. Update service:
Our system (10.3.1.A.2.67) is now way better than it was when Sony launched it at first. The users that don't have changed anything in the System folder have received updates in an optimal frequency: I bought this mobile less than one year ago and have already received a dozen updates (including some patches in apps).
Congratulations, you have a good mobile.

Root, Greenify and TiBu the bloat - that's the biggest killer of any smartphone, regardless of manufacturer. Granted, Sony is better than most for not including a lot of crap, (I'm looking at you Samsung!), but if you're never going to use the program, why bother having it installed, cached and possibly in memory?
Root your device and TiBu uninstall the apps you don't want. I reduced my usage from 1GB of RAM at idle down to around 400mb mark.
I greenified almost all apps, and now I get roughly 10% drain over night with all features on, WiFi, NFC, Bluetooth and 4G, no Stamina Mode!

thanks to all of you for your answer but i'm using the leaked rom without root? =/... i'm thinking in use cyanogenmod how good or bad run this rom???
