[Q] Rom with the best battery life

I was just wondering what rom has the best battery life?
If u guys had some user experiences or statistics, it would be great to hear them out.
The best battery life I've had so far is with AR3.3.
How bout u?

I got the best battery life with coredroid v3.3 and lee's kernel v2.2.8.
2-4 mA in standby.
And it's by far the best combination when listening to music. It drains about 60-70mA whilst other roms drain 80-120mA

from the different roms i've tried it's a close call between cordroid v3.3 and leedroid 2.2.2/3

What Rom to Use
I agree with Coredroid being a good stable rom. Be sure to get a good radio to. Use currentWidget to find your battery drain after radio switch.
I use radio: Radio_12.35d.60.140fU_26.08.03.07_M_Test
Tested the: Radio_12.48.60.23U_26.08.04.07_M3 but GPS did not get a fix after 15 minutes. b.t.w. Radio_12.48.60.23U_26.08.04.07_M3 is from HTC Desire S T-mobile.
Rom: CoreDroid_Desire_HD_GB_2.3.3_V4.9_Stock_Release
Rom: Restored original bootanmation (don't like the CDroid animation)
Radio: 12.35d.60.140fP_26.08.03.07_M on T-Mobile

Thanks for the responses. I'm currently using Android Revolution 3.3 with Lee's kernel 2.2.9 and the battery drain is 180-570mA when im using the phone (internet, calls etc, i dont even play games) and 3-40mA in standby. What is the matter, what should I do?
PS. No coredroid, I dislike the theme..
EDIT: And yeah, I do have the right radio for the ROM.

The battery drain while using seems normal. Its due to the DHD's 4.3" screen. It eats the battery like the cookie monster his cookies
40mA peaks are normal if they don't accur too often. How much peaks do you have over night? Try Battery Monitor Widget to monitor everything related to your battery.
And by the way there is no right radio for a rom. It depends on your location and your provider. Lee's recommended radios caused a high battery drain for me. Flashed another radio which wasn't recommended and the battery drain was gone
PS.: if you don't like CoreDroid's theme you can flash any other theme you want over it

Doesn't the posts above answer your question?

LeeDroid gave me good battery life but I've switched to CM7 now and with wifi and gps on battery drain is only around 4-5mA in standby and plus playing music drain is around 60mA. This is the best battery usage I've experienced so far.

I think all Roms with Sense habe a good battery Performance. At the Moment i'm using ultimate Droid ans so i have now 85% that means 15% in more then 3 houres..

How's the battery drain when you're on a call? I'm using Revolution and it does pretty good when I'm doing anything BUT on call (between 40 mA to 300mA for browsing, emails, etc) but once I start making phone calls it jumps to 600mA+ somehow.

Not all the sense ROMs. Revolution HD is really dramatic(Yes, with the same radio).
I am on Rcmix now and that one is really great with batterylife.

I'm on stock rom, and it consumes about 1% per hour on idle.

But CM7 isn't "a beautiful sight" otherwise :/
Is it possible to have Sense with CM7? Or at least a few of Sense UI's apps, such as calendar or dialer?

That's what I though until I flashed it and messed around with it. Now running ADW EX launcher and screen density set to 180 is beauty.
Now I realize how ugly Sense really was lol.

I currently have Android Revolution HD 3.5 with Radio 12.35d.60.140f_26.06.03.24_M2. In my eyes the battery performance pretty good and better than that found in earlier versions of this custom rom (3.3 & 3.2) and way better than stock.
Leaving the "what is causing the power drain" aside, one item that might be worth looking into are some CPU management add-ons such as:
SetCPU (small charge)
No Frills CPU Control (free)
These will manage your CPU power and your settings will persist between reboots. I actually use No Frills (and overclock to 1.2Ghz), but I believe that setCPU allows you to select CPU profiles so this may allow you to stretch the battery life when the phone is idle.
Just a thought....hope you find this useful.

Best SetCPU Config for Desire

Hello
Does anybody use set cpu with HTC Desire ?
I would like to know wich settings work the best for you. I am trying to get the best compromise between battery life and performance.
Thanks

128MHz - 998MHz ondemand. I get more than enough life out of it. I found that if your using AOSP and not really doing much on it like just texting or calling people, capping the max to about 600MHz or 500MHz if you want, works a dream and you get even longer out of it.

Smartass is better or worse ?

I do not see any real difference between smartass and interactive in term of battery live and performance.
On demand seems to drain slightly faster than smartass.
I set my Desire to 384-1136 with interactive govenor.
I charge it once i a day each time before I go to bed anyways (sleeping time usually23.00 - 05.00), so further battery saving is not necessary to me
Edit...my normal usages are:
Syncs (no auto sync by opening):
Friendstream 4 hrs
News 4 hrs
Weather 6 Hrs
push Yahoomail
push Googlemail
push Whatsapp
push EBuddy
Active background :
Lookout antivirus
No app killer used
Phone calls : about 1-2 hrs each day
Music listening mit DSP add-on : 4 hours
Fruit ninja (man! this is addictive!) : 1 hrs
Browsing (Dolphin HD + Android market) : 2 hrs
welll....every time I charge my battery it is about 15-25% left till out of juice...if I use my phone more than those, I have to charge it earlier (more than once a day)

245 - 985 MHz Conservative give mere 36 hours power and running smooth.

For me the battery has never lasted more than a day... Even on my un-rooted one...

BTW: Battery live depends on many things
1. Your ROM and kernel
2. Your runnning application, syncs, etc.
3. your usage and settings such as cpu freq, display brightnes, airplane mode, etc.
4. Received signal quality.
5. The condition of the battery...is it top fit for example?
It is difficult to measure the battery live.
@atuladhikari : battery live has nothing to do with rooting..

I don't like using any of the other governors since I get lag. I hate lag. OnDemand gets rid of the lag for me. I've had it before where I was using smartass and it took ~30 seconds for my screen to turn back on from idle. I wasn't too impressed.

setcpu
thanks meaple for your advice
i think that set cpu is fine on "ondemand" for some roms and for others roms no
set cpu is included on oxygen settings and running well

Cool, I need to download Setcpu

128-998 ondemand
screen off 128-384 ondemand
in call 128-384 ondemand
I get very good battery and performance with theses settings.

Which app do you guys recommend? Tried overclock widget doesn't seem to be working.
Am on Insertcoin stock GB rom.

DidI do that?....I did.... LOL.

I used to use set cpu
set a profile like
Smartass
on charge - 1113mhz
80% - 100% - 998mhz
59% - 79% - 600mhz
35% - 58% - 500mhz
Screen Off - 300mhz
Priority was higher for lower battery %
BUT I stopped using it because of the little bugs, like when it changes to 384mhz for no reason after unlocking screen
It also affects the standard script with the rom you install, so you can never uninstall it properlu, you have to do a full wipe install and never install it, until I did that my phone was always a little laggy
I prefer my phone without it Each to their own

@shankly1985 - you didn't noticed wakeup lag with 128 MHz?
I must use 245 - x MHz to properly and fast unlock my phone.

Best Setcpu config for Desire is - no Setcpu at all.

I couldn't agree more with you. Experienced all of the above so no go.

245-1033mHZ with smartass give me two day out of my desire loaded with insercoin 1.0.9 with v06 kernel !
I am mostly sending Text message and some calls.

Not at all mate, I get zero lag on my phone. when I check the info on the setcpu app and time in state 128 is at 85% so my phone is using very little cpu.

[Q] Transparent status/notification bar in leaked GB?

Hi there,
I'm using CM7.1 with Meizu theme now, but I'm looking for another ROM with less battery drain and 720p recording. I decided to go for the latest leaked GB, but I'd really love to have transparent status bar like the one I have now (you can take a look in how this theme look like here) - Launcher isn't a problem, I'm going for XPeria Arc's one.
So, my question is: without the theme chooser app from CM7, is there any way I can get a transparent status bar without having to mess around with framework-res.apk myself? In other words: is there a transparent statusbar there already made for Defy?
I know there is a simple way to apply themes by flashing them via Recovery, 'cause Barebones has various themes available this way here (since this ROM uses CM7 instead of GB, CM7 themes work on it - the themes on this thread are only for the Froyo version).
Thanks in advance!
P.S.: I know it would be better for me to post this in the themes & apps section, but, honestly, almost nobody uses that section for this kind of thing

Wow, that actually looks pretty good.
I'd like to get it too

You can try MS2Ginger fulfills all aforementioned and the best battery backup I've experienced out of any 2.3 rom.

No transparent statusbar (only default GB MotoBLUR bar), but seems ok: has good battery life and 720p rec. What are the differences between blurred and deblurred versions (besides MotuBLUR, of course)? Blurred seems to be more updated, any advantage in getting it (since I won't use any BLUR apps)?

My bad, mistook the Notification bar for the Notification pane.
The De-blurred version lacks not just the services but even the Motoblur interface ( ADW included) , not any significant improvement on the battery though. So I dumped it after 2 days of playing around been on on blur ever since and dont worry even the blurred version lacks services like FB etc as the Creator couldnt get it to work and you can always remove unwanted apps.

Tried it for a few days, now I'm going back to CM7. My phone is horribly slow since I flashed the ROM (even before I restCored my apps w/ Titanium Backup), with CPU Load Timeline reporting 100% CPU use most of the time. Too much CPU use = crappy battery life: it can barely stand 6 hours. Just as an example, I tried to get it off charge (was 100% charged) while sleeping. When I woke up, 8 hours later, it had less than 60% left - that means 5% per hour, without even USING the phone: mobile data was set to EDGE, WiFi was off, no background apps running... That was enough for me. I'll stick with CM7, even with its faults, it's still the best ROM available, I think.

Hmm weird , the battery only drops 3% max for me overnight (10 hrs). The Rom is overclocked to 1100 mhz by default , Did you make sure to underclock and rest assured undervolt it?! I also removed a lot of system apps and services that i dont use. My usage can be classified as average with 2-3 hours of wifi , 1-2 hours of gaming and I am on a 3G network but the data delivery is usually set to off and it lasts me 2 days.

How do you try to make your Play's battery last?

When I'm not using the internet or playing games, I literally set my max speed to half stock using the OnDemand governor, I always keep WiFi off unless I'm home and keep 3G unless I check my facebook or upload an image, 3G usually reactivates then deactivates itself with MMS I believe, not exactly 100% on that, correct me if you'd like. My stock battery lasts for about 30-35 hours under constant texting plus the way I use my phone. When I play games, I set clock speed back to stock and keep 3G off, whether I overclock or not depends on the game.
The UI loses a little FPS but I'm cool with that, and onscreen keyboard response is a little sluggish but that doesn't bother me either. I might try setting my max clock a little higher and try a different governor. My ROM and Kernel are in my signature.

Never really had to "try"... on stock 2.3.4 I usually get incredible game time/usage time just from keeping auto-brightness on.
I am going pretty minimalist on widgets though; nothing but LP Sense's own widgets and a clock., so that may also contribute.

I keep the bar on maximum brightness, but AFAIK, that setting is ignored by the auto brightness.
And no tweaks. TBQH, only tweaks I know how to do is maxing camera quality and spoofing R800a to be an R800i.

[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.

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.

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.

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.
