hey I've been looking around for the answer with no luck can anyone help.. which rom is currently easiest on the battery as in consumes the least amount of energy/resources.
thanks
Aaron,
For the most part, a lot of these roms are based off of the base version and then tweaked for optimal performance. While there are some that are feature laden (ie. loaded to the kills with tweaks and background processes) and some that are fairly basic (a few features, stripped down ROMs), battery usage all depends on how you setup your phone.
I've got the Pegasus series ROM on my touch diamond and it works fine (battery life still to be tested) and I haven't noticed a serious detriment to my battery life yet as there are tweaks in place to maximize power savings.
Even with the stock ROM (Bell in my case) battery life maximization has always been an issue.
Here are a few tips to maximize battery life (applies to pretty any rom, stock or not):
1. If you don't need that fancy 3D interface, kill it and go with the basic home screen.
2. Make sure to turn off your data connection when not in use (will go into an on-demand mode if you have anything that runs in the background to get updates once in a while). Make sure WiFi is shut off as well (serious battery drain) and the same goes for bluetooth when not in use.
3. Dim your screen to the point so that's still usable (brighter screen = more power usage).
4. Put your phone to sleep when it's in your pocket instead of waiting for the default time out (press and release the power button to sleep it, do the same to wake). It might only be a 30 second difference, but it adds up a bit.
5. Reduce the number of background running applications to essential ones (ie. e-mail is essential, MSN not so much). Kill any widgets that don't really need to be active (twitter and facebook ones are notorious for sucking up battery life).
That's all I can really offer for now, the more seasoned members can help you out on what ROM is more battery friendly. I've been lurking for a bit, it's time that I start contributing.
thanks alot for your advice, but perhaps offering further explanation may help and others who may consider providing a response..
I am running a Culkins rom and dual booting an Android rom. What I am looking for is a rom I could run on my phone that would not consume much resources or battery life in addition to the resource intensive Android rom.
Thanks again..
Okay, that helps a bit. The culkins rom isn't so bad when it comes to power management. Check out the diamontweaks app to help configure some options. He doesn't have a lot of running processes in the background (a few too many apps than anything else if you ask me).
My ROM (on PPCG) isn't bad at all. Lemme release an update soon.
thanks for the help both of you.. with respect to your post MrObvious I look forward to using your rom when its released do you know of any "skeleton" type roms where its just the bare minimum required to run that rom?
Simple Poll.
Have you seen a decrease or increase?
Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.

I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD
OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%
Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).
So I've been testing CM9 for quite a while now and can't help notice the battery life has been reduced heavily compared to Honeycomb 3.x.
Now, I don't mind that my battery life gets a bit shorter as ICS brings more features and might be more power hungry. But I went from my tab being able to hold a charge in standby mode in 3 weeks to barely 3 days. And if I use it more heavily, it barely holds a day, which is worse than my Motorola Atrix and that's just not normal.
Now, I've been discussing this with pershoot and for him it must coming from something I do. Honestly I don't see what. In the Honeycomb days, I used to have so many apps installed (may 100-150) and battery life was fine. In CM9, I'm running 50 apps, the essential ones. All the apps that could be power hungry have those settings set to off. No push notifications, very large updates intervals (a day) or none when possible. Also, I run most on these apps on my Atrix (which has more apps installed) and my battery life is way better on the Atrix.
In usage itself, I don't see any change, it seems the tab consumes the same amount of battery than before. It's the sleeping battery life that is terrible. In my case, in sleep mode, wifi is off, brightness is set to Auto and data is off (not the signal itself but I tried to take off the SIM and the battery life is the same).
Honestly, not having to care about charging every day is a must feature for a tablet.
I'm running now RS125 ICS, based on stock and the issue is also there. So I wouldn't say it's something related to CM9 but more on how ICS behaves with our tab.
I've read report of other people complaining (with the 10.1 also) so I wonder if it's a general issue. Could you please fill the poll so we can see if there's an issue and if so, how could we identify it ?
Don't hesitate to describe your tab usage and battery life !
Thanks !
For me worsts battery life was with the official 3.0.1. 3.1 was big improvement. 3.2 and 4.x were a little bit better than 3.1.
Got gmail and exchange push notifications turned on, but most of the time the tab is connected to the wi-fi, not to the 3G network
Attached is my personal stand-by record on the 10.1v. I think it was with one of the first pershoot's CM9 roms
Hi Danny,
Same for me. Especially the standby mode I see a battery drain.
By the way, somehow my battery usage is not working since I moved to the official ICS ...
Cheers
No problem @all. Stock 4.0.4 with OC kernel.. Looks like this:
GT-P7500 [email protected]
Kernel info...
GT-P7500 [email protected]
I've got a 2 year old I9305 from the UK that's rooted and using the German 4.3 Stock ROM (couldn't update to 4.3 with a UK ROM at the time).
The battery life used to be much better - I've had it for a year (I bought it as not working from a family member and then got it running) and would easily get over a days use including hooked up to the wifi most of the day, 2-3 hours with the screen on etc but now I find I'm often getting less than a day with similar use. I've since done a factory reset and re-installed my apps but it's not improved anything noticeably.
I rotate through 4 Anker 2200mAh a genuine Samsung and a Samsung battery bought on Amazon (genuine - not sure about that!) using a wall mounted charger to do most of the charging as I spent the last 8 months traveling and didn't want my phone sat around in dorm rooms plugged into the mains while I wasn't in the room.
If I only had the one battery then it would make sense that it's ability to hold a full 2100mAh charge would drop after a year but with 5-6 batteries taking the strain, I'd assume that this would be less likely. I was looking at apps like Nova battery tester and An tu tu Tester and will give them a go tonight on which ever battery is in the phone - are they any good?
If the batteries are still taking a solid charge then I guess it's time to go back down the route of a custom ROM but as I travel a lot, I'm loathe to mess around with my S3 too much. I had an HTC HD2 that was running CWM and a couple of different ROM's and it died on me a couple of times while I was on the road. That was less of an issue than it will be now as I was traveling with a netbook - the S3 is my only device now so I need to to be stable. I'm not averse to going through the process of putting a ROM on the phone if there are a couple that are known to be super stable and lighter than stock on battery life, but if I can stick with my stock set up with some tweaks...I've got All in one toolbox controlling which apps load on boot, greenify to hibernate apps (instead of a task killer knocking them off) and No Bloat stopping the bloatware from running.
Any suggestions would be most welcome.
Hmm.. As you are using greenify, boot apps control and no bloat, you are extremely in control of your rom - that's good.
I think that there would be negligible to none difference in battery life between your rom and any custom. Stock Touchwizz roms are said to have better battery (from my own experience too), therefore installing any custom aosp rom should be rejected.
What I can suggest? Download some recent full rom from sammobile or live updates samsung (search google) and flash it through odin. Or maybe you have tried it?
However running one rom for few months may have some influence on battery too.
Also, installing custom kernel is the thing that may help you optimize battery/performance with few interesting features. Boeffla has great description and faq on the website and user-friendly config app. But that's only if you want to experiment (it is still rock-stable) a little bit.
Try custom
The 4.3 JB upgrade is well known as a battery killer. I had stock 4.3 from Base (Germany), but the 4.3 from H3G (UK) is the same for battery life. I have used CM 11.0 as well as others, almost all are nicer to batteries than stock.
Currently I use the S5 Elite Lite Rom. The current version 1.4 seems to be very stable even with both cpu and gpu overclocked. Battery life is still a little better than stock 4.3 and that is despite not using the deep sleep feature. CM 11.0 is even better for battery, at least for me probably down to there being none of the Stock bloatware. Hope that helps.

The current ROM was one from a year ago when I first set up the phone but I've since done a factory reset and reinstalled all my apps.
I didn't realize that I could run a custom kernel with a stock ROM - that's something I'll look into. I don't have a custom recovery set up as the last time I used one on my HD2 I had nothing but trouble and, as I said, I need this set up to be reliable over pretty much everything else.

How long have you been running S5 Elite ROM? I think I'd probably stick with CM, though I'm intrigued by some of the other stuff out there, but ideally I'd like to stick with a solid, stock rom without a custom recovery.
SYMLY, I don't really understand what you meant in your post.

I have been running the S5 Elite ROM for a couple of weeks only. In that time I have found it very stable, by stable I mean no random reboots, and no force closes. It is not completely glitch free for example some apps need to have the sd card unmounted before being installed. I run it overclocked at 1.8Ghz and slight over clocking on the GPU too. Antutu score was around 20800. The S5 Elite ROM gives me a stock look including the S apps I want specifically SPlanner and SVoice.
If you really want to have a completely stock rom with good battery life you might need to consider downgrading to a 4.1.2 rom from Samfirmware or waiting for the fabled 4.4.2 upgrade. I've been waiting on that for months and finally gave up, hence I'm now using the S5 Elite.
Best of luck deciding, I guess there is no one size fits all solution.
Roms that may help with the batteries.
So far i've seen that stock roms usually consume less battery than stock firmware . something that may help you is deleting apps that you know you'll never use at all. that removes the autorun consuming less battery. Now. among the best but remains on 4.3, is the Alliancerom v3.5. i've seen that my battery drained less faster than on stock firmware. but also due to its kernel it can be controlled the amount of mhz using for process (if you don't know how to use it, do not touch it) . and also the charging rate can be controlled.
If you want a touchwiz based rom, i recommend AllianceROM V3.5 or AMCHA rom v6.11. Both roms are super stable, Alliance lags quite a bit though. Ive been using AMCHA (with S5 theme and agni kernel from aroma installer) rom for awhile, so far so problems and pretty good battery life
You can also try archidroid and neat ROM they are one of the best touchwiz 4.3 roms
To be honest, I'm thinking that I'd rather go down the route of checking over my batteries and trying out any other utilities that might aid in reducing the battery use of my S3.
If I were to go down the custom ROM route then I'd be more interested in the kernels as it's been pointed out that they're going to have more impact on power consumption.
So, any suggestions for utilities - as I've said I'm running all in one toolbox, no bloat and greenify. What about apps to check the actual capacity of the battery?
Well. That been said. Then my suggestion is that you delete apps you dont use at all. Actually that also works in alliancerom 3.5 or any rom or stock firmware. It is obvious that if you delete apps that have autorun enabeled by default when you restart or turn on it affects the ram and also affects the battery draining. My alliancerom 3.5 battery last even more than the original firmware. I've deleted plenty of apps i didnt need at all. More like junk to me. Of course. All of this you can do only if you are rooted. Also another suggestion. Ebay sells i9305 extended battery. It comes with the double, Triple and even more amount of mah for pretty good prices. With them i can assure you that you will use your smartphone with the highest performance without been worried of low battery until night.

No... nono ononono.
Stock kernel will have similar battery performance as agni or boeffla (on same settings). Sure, custom can bring a enhancment or two, but the battery improvements would be minimal.
A custom kernel will only improve a stock kernel battery performance if the stock kernel is ****ty to begin with. Not the case with TW 4.3
It's the rom, and it's apps and your apps.
How about installing Better Battery Stats and posting a few screenshots?

Cheers for that. I'm aware of the obvious basic stuff affecting battery use like cutting down the number of running apps (hence why I use all in one, no bloat etc) but no little about kernels or their battery related benefits.
That app sounds good, I'll stick it on today and then happily post a few screenshots for you to look through. I've just had a look and it's a paid app - bearing mind I'm only needing the use of this once or twice are there any similar free ones.

If you have zillion apps (like me), then they tend to update frequently, use more and more resources, and services.
I was astonished to see that some apps that i installed just in case - like ebay, skype, tripadvisor - and never used yet, - were running services and have put themselves into autostart!
if you are rooted and use autostarts utility, you can disable a lot of junk in the on start and after start events.
you will immediately see the difference in boot time.
i also deinstalled the apps mentioned above, and battery usage back to normal.

Ok, for those new to these things I'll give you a brief run down of the 3 apps I keep mentioning to save people posting suggestions for things that they already do....
Nobloat (root) - delete (including permanently) any apps including system apps (get rid of the pre-installed bloatware.
All in one toolbox pro (there's a free version) - I use this to clean up my autostarts - I can determine which apps will load on boot - both user apps and system apps.
Greenify - hibernates apps rather than killing them so they don't then autostart. There's also a way to have apps brought out of hibernation if their push notifications come through.
All in all, 3 very useful apps.
Feel free to mention any other ones to help things run a little smoother.

Do what i did, i bought a 6000mah mbuynow battery off ebay which seems to be around 4000mah true. It lasts about 90% more than the stock battery. im still not impressed with the battery life as phones these days can achieve the 8 hours of screen on time that i get with my extended battery with there stock batterys. i9300 has better battery life for some reason even though my i9305 is undervolt and underclock

That sugestion is completly wrong. A 6000mAh battery is huge and adds a lot of weight and bulkiness to the phone.
Exactly! it's perfectly viable to live with a standard battery on our device, if you use a right rom and de-bloat.
Say no to bulk! ))

Hi,
first, thanks to Maclaw & co for their s3 ports!
I've flashed CM11 on a new phone, and am very happy with it. The only straight up bug I found: reading contacts & SMS from the SIM card was impossible. Reverted to stock backup, pulled them down and backed up, then went back and imported them in CM11.
On battery drain - this is my first smartphone, and I ditched stock immediately. So I am missing some frame of reference here. Also I just got this two days ago, so I will need another week for some real-world statistics. But from what I've seen so far, I kind of doubt it will make it through a single day. Now I don't expect it to hold charge for a week like the old Nokia I am migrating from, but still...
What kind of battery life can I reasonably suspect? I understand "it depends", but let's say location turned off, mobile data only when needed (maybe an hour/day or so), dark themes, dim screen, etc.. Basically I am trying to figure out if this is an issue with the mod/build, or just how things are in android land.
Now I do have some suspicions that cpu load is a bit excessive. During "idle" (no apps running but htop, location&mobile data off, wifi on), both cores are at ~30% consistently. Attached is a screenshot after 1) bootup, 2) turn off screen 3) turn back on after 30min and start htop in terminal. The base system also seems to draw more power than the screen (set near minimum brightness). But again, maybe normal?
I went with CM11 because it looked like it was the most widely used / best supported one, but if it actually has some battery issues I would need to try out some alternatives. Would be happy to help in debugging if there is something I can do as well.
Have a look at Slimkat. Been using this for quite some time and I have no complaints about battery life. Obviously the battery life will depend on how and what you use your phone for.
Pacperformance is a system app in Slim so you can set your governed, CPU Max/main etc. Use wake lock detector too just so you can see if pacperform is showing your not getting deep sleep.
I have used many, many custom roms and CM11 has never really appealed.
Good luck in your quest!

Thanks for the tips, I'll check them out. I was a bit wary with trying out other mods since I'd like to not spend too much time on it and just have it stable, but I think I will just give them a go - easy enough to revert from a backup. Regarding governors, I checked and mine is set to interavtice, there are a bunch of others available though:
Code:
$cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
abyssplug pegasusq hotplug conservative ondemand userspace powersave interactive performance
Hmm, most of them I've never heard off - any preferences?
BTW, for whatever reason battery drains a lot slower now (maybe it just needed a few cycles to settle in?). I also verified via adb shell that it idles at around zero load when the screen is off.
