[Battery Showdown] Top captivate roms battle it out! Updated 3/31 w Phoenix results

Test # 1 Video Streaming Over WiFi
ROMS Tested So Far:
Continuum
Serendipity
Precision
Firefly
Cognition
Phoenix
Paragon
Twingerbread
Supernova
Darky's
di11igaf
Dragon
Andromeda
**DISCLAIMER**
Keep in mind that results will vary for each phone and just because I get a certain battery life using the rom's and kernel's listed below does not necessarily mean that you will.
Tired of constantly flashing to find great battery life only to realize the rom didn't meet your expectations; then this thread is for you. Over the next few weeks I will test every rom imaginable and post real world results that will include battery stats, linpack and quadrant results.
**This is not meant to put down any particular ROM. Without our great dev community my captivate would have been returned and thank you all for your hard work.**
[Goal]
To provide the captivate community with real world results from top roms in everyday usage where battery life is the key focal point, but performance is not affected. Hopefully this will help save you time from having to flash multiple ROMS.
[Roms]
*This list will continue to grow*
Stock 2.2 kept fcing so will test it on test 2 this evening 3/28
[Usage]
Each night I will run the exact same VERY LONG documentary using VLC stream and convert and current widget.
[Specs]
*Every rom will run "out of the box" meaning Kernel, Modem, Settings all default to how it was cooked*
° Default clockspeed 1000mhz (as suggested by a smart person listed below)
° 40% Brightness/Screen Timeout Turned Off
° 100% Charge each run (0mV to make ryude get a chubby)
° Auto Sync off
° GPS off
° Zeam launcher
° VLC Steam & Convert used w/ same long documentary used each time
° Phone is placed in exact same spot every test and is unplugged as soon as I hit play

Goal:
In previous tests I tested on wifi using a vlc stream & convert. With this way of testing I'm hoping to get more realistic real-world results that you can use as a guideline to a roms overall battery performance . Keep in mind your results may vary.
Testing:
Every night I will set tab reload to 15 seconds and it will continuously reload XDA website until the phone dies. It will be placed in the same spot in my house every night and will be ran on phone data, thank god for the unlimited plan.
Applications I will be using:
- Dolphin Browser HD
- Reload tab plug-in
- Current widget
- My Settings
[Specs]

° Auto Sync and GPS On (To help give near real world results)
° 3g
° Zeam launcher
° Phone is placed in exact same spot every test and is unplugged as soon as I start Reload Tab Plug-in.
**Will be running all tests on 3g as some ROMs do not have HSPDA**

Cool. Any chance you can add stock Froyo to the list as a reference point? It would be interesting to see how much custom rom's are improving over stock...

Great suggestion only thing is I won't be able to undervolt so numbers will not be accurate to this testing, but I might run the best two roms after I'm done testing at there defaults against stock froyo.

Since many users are set at the standard 1000, would you consider the testing at standard 1000 speed for a more accurate battery life any user can expect. Just a suggestion

Sounds like Precision should be included, with the black theme it easily gets great battery life.

Is this under-clocked? I am on the same ROM with speed at 1000 with no under-volting.
I get 1600+ scores on quadrant, and 14+ scores on linpack (tested out even now).

Yes I listed in the specs what they will all be running at. All are uc/uv to 600mhz.

I have been waiting for something like this but I assume that the devs would all be up in arms if someone rated their ROMs higher/lower.
If this thread will be allowed to continue, totally looking forward to the results.
And you should totally throw Precision into the mix as it seems like the de facto battery saving ROM as it skimps on a few services.

Personally, if I was a dev and saw that my rom wasn't too good, I would try to make something better. So who knows how it turns out. A little competition wont hurt anyone, and hopefully have better roms! Btw, good idea with this

Just finished di11i on to paragon. The theme on di11i is very nice too almost a carbon fiber look.

add Torch 1.5
Also try Torch 1.5. So far been outstanding in battery department.

I know this doesn't help as far as battery life, but just for a reference as far as stock 2.2:
1. Linpack - around the 14 mflops (sometime in the 13 range, sometimes in the 14)
2. Quadrant - 1050 or so
3. Nenamark1 - 51 fps (not sure if anyone uses that one much, but thought I would throw it in as I had it available lol)
I would estimate the battery life if I didn't use the phone at all (just left it sitting in standby) would be at 60hours plus, as I get up to around 40 with light usage on 2.2 with battery to spare (haven't run it dead yet to be honest on 2.2) Still a little early though as the phone hasn't been drained and recharged full thus far.
I just checked my phone, and I have had it on for over eight hours, and I am at 92% battery left. I have hardly used the phone today (just a few texts is all), but going on that I should get around 80 hours on a single charge if I just leave it sitting there.

Great idea. I'm a huge continuum fan

Charge drain charge drain lol gonna get online now and buy a new battery just incase i destroy this one.

LOcation matters
I am using JuicePlotter to monitor my battery usage closely. From what I see, different locations give dramatically different battery life. At home my battery drops 1% per hour. At work 20 miles away it drops 2% on captivate modems but 4-5% on i9000 modems. So the signal strength, cell tower type make big difference.
I have tried multiple Cog ROMs and Paragons ROMs, currently on Twingerbread 3.2. The best ROM in terms of battery life is cog 3.2 for me.

Yea but most people throughout the day are on the move and all I'm trying to achieve are results based on that. The constant will be the kernel in this test that way any thing I log can be directly attributed to the rom/modem. This by no means is the end all, but it will give the community a great idea of where each rom sits.

Interesting kernel choice. I've heard Suckerpunch lauded, but that ignores the fact that most of these roms flash with a different kernel by default. Is it a better test to run them all with the same kernel, or with the one they chose?
I dunno. Might be interesting to test and formally see how much kernel choice affects things.

Lowest Cpu setting

Im gonna try my MT4G @ SetCpu 537 max 122min.
Anybody ever try using that daily?
Wonder what the consequences would be.

Mite lag the whole day
HTC Glacier (Black) - Virtuous Unity 2.39/Kernel V9 Unity/Beats Audio/Good Screen/Good Emmc

We'll see Im running it on Miui ...

I don't think you'll see much improvement. That rom already gives over a day's battery life.
At some point the phone will take longer doing normal tasks and the length of the task will outweigh the battery saved. It would be interesting to find a sweet spot.

Yea that's what you have to realize. You have to maintain a healthy balance!
I run 1017 ghz smartass. No setcpu or anything. Text practically all day. Phone calls for maybe half hour collectively, game for a good hour or hour and a half, cause I get bored. And a lot of browsing XDA, Fantasy Football, and tracking the packages I order. I'm so happy because with this balance I get everything flying by my fingers and still amazing battery. Running Royal Ginger 3.0 with there Kernel. Amazing! :-D

Possible drawbacks might be WiFi dropouts, sync failures, etc. There is a minimal allowed frequency for a device, and it's for a good reason.

I had trouble when I set the min below 350 (or whatever the exact value is). It gets laggy after a wake up for a few seconds if I go lower. So I'd wake the phone, then have to wait a few seconds to do anything after any click on any icon while it spun up the extra power.
At 350 it was plenty to wake the phone up into a usable state and I didn't notice any lag at all going form 350 to 1000 when it needed the extra power.
Running Cyanogen and using it for 30-45 minutes of calls a day, ample texting, and 30-45 minutes of Angry Birds I get 2 full days out of the battery before I need a charge.
But I also don't leave data on. That was the battery key for me. Data turns on in 2 seconds, so I only turn it on when I need it. If I want to see a website I hit the data button and by the time the browser loads I've got a connection. Since I don't care about instant notifications of email, I just don't need data on all the time so there's no point in using battery life for it. If I ever do need it on constantly, it's available to me and I'll drop down to 1 day of battery.

Same settings and about the same battery life here on CM7 with demonspeed kernel. The smartass governor with 122/1017 works great

I'd suggest not doing that but just keep the default settings by system.

[Q] Is my Deep Idle Working? LOOK!!!

Please tell me if my Deep Idle is working. I imagine that there are others with the same question. Here is a picture.

No. You need to flash the Bluetooth framework fix. I take it you are on stock/a stock based rom?

Nope im running CM7 with Matrix kernel 11.5
also i dont use BT

Turn on Screen Off Max Freq. Also, you mean CM9 right? And i believe the latest (a20p1) has the bluetooth fix incorporated.

CM7 with a ICS Theme and even though i dont use BT i still need to flash this? Where do i find such a God given thing? lol

Sorry, for some reason i thought you said matr1x 14.5. The bluetooth bugfix is, as far as i know, only for ICS ROMs (bluetooth is always "ready" to turn on, which forces only top=on time). Turning on Screen Off Max Freq will hopefully give you some deepidle time.

Thanks bud. Not to be a nooob and all but how long does it take to initiate?

I'll get some top=off time after about 20 seconds with nothing at all in the background and using matr1x 14.5, stock ics, 100/1200, lazy and screen off max freq. I would say if you don't have anything after a 2 or 3 minutes it's not activating for some reason.

Cool ill check that out. What ROM/KERNEL combo do u have? what the battery life on that 100/1200 set up?

Cool ill check that out

I said the ROM and kernel in the post and it's in my sig too. With 4 hours of gaming and 2 hours of general internet browsing i got around 12 hours with weak 3G signal. Battery drops very little with no use, somewhere around 5%/10 hours. I havn't noticed any major battery drain OCing to 1200, just a little bit of heat on demanding games. Drain is proportional to increase in perfermance most of the time.
I'd definitely be confident going 2 days with a single charge as long as screen time is kept under a couple hours. ATM i'm playing around with different governors to get better battery life, deep idle won't be any use to me for another month or so.

This is know as the CAM bug which was fixed in ics kernels. Every time you reboot the phone your camera is active and prevents the deep idle from working. Opening and closing a camera app closes it and deep idle can start working.

Isn't the cam bug only fixable by disabling/removing google talk (or installing the non-video one)? Otherwise you are forced to open and close a camera app each time you reboot to get any top=off values.
Also, i mean true stock, google OTA. The NS4G doesn't have this yet.

Could you please explain what does screen off max freq do ? I have tried to get into those things May be now is a nice time

While screen is off, allow the processor to use max frequency (stock is 1000mhz). This allows "race-to-idle" which the hardware is capable of, effectively reducing the amount of time the CPU is processing (and therefore powered), reducing power consumption and further allowing deep-idle to work.

[STATISTIC] [USERS NEEDED] Miui battery drain problem

Woops wrong category, sorry ^^ Please move it to general

Hey guys,
as you can see, I´m back And it´s my first target to fix the massive battery drain on Miui. The first thing I do is to compile a new kernel for Miui, but I need your help, too.
I have to locate the application that uses the battery most, so please go to Settings -> System -> Battery Settings , make a screenshot of it and post it in this thread. If you have the time to, please use Spare Parts, too and also make a screenshot of the battery usage.
Thanks for your help!

Well, BatteryMonitor and SpareParts are pretty usefull, too. If you have the time to it would be a big help for me

Will edit this post in about 5 minutes with the required screenies. Good to have you back fuss good luck.
edit1: Android System eating up the most battery on normal usage. Getting screenies for you now...
Edit2: new find, alarm manager is using up random battery. I don't use alarms. Uploading screenies, sorry slow internet
Sorry couldn't do spare parts cos I'm charging.. just started a few minutes ago D:

At the moment I drained my battery with games so it wont provide you with the correct stats (I guess) Charging it now will post the screenshots asap

what are you needing from battery monitor?? it display the same as spare parts and system^^
updated previous post.

My Battery Stats

damn! xda needs spoiler so bad....
it'll be better to upload all images at imageshack.us album (?) or some other way which dont need that much scrolling

Battery is normal for me (or not?)
Hi, as soon as I finish the full charge, i'll post some screens.
Personally, i think i'm not having this problem. Battery lasts for a day and a half with a normal-heavy use.
Salut!

Ever since I turned off overclock and switched to 2G only mode and switched to 1000 max with interactiveX and bfq governors; I get very good battery life. 1.5 days on heavy usage. 2 days on moderate and 2.5 days on light.

did u install any battery saving app e.g. juicedefender ?

Nope nothing. IMO its HSDPA which is causing a lot of battery drain.

Fuss, I wouldn't like to difficult more your work, but I have to say that yesterday with MIUI V9 + VurrutKer v2 + MAX 1000 MIN 300 + sio + SmartassV2 I got an awesome battery life. Here in the forum people usually have like 2 day battery in MIUI ROM but I don't. I have to charge it every night and yesterday I was in 53% when I went to bed. Awesome. Hope it helps. Thank you

Advice on battery life, Beans 14/lean kernel

Hey guys, I'm new to this forum but not Android Central. Anyways, I just recently switched to jelly beans build 14 w/lean kernel. For some reason my battery life is just terrible. I'm just barely making it through an 8 hour workday, and that's not even using it that much. I was wondering if you guys had any tips for good battery life on this ROM/Kernel combo. I do have set cpu installed and running but I'm only Overclocked to 1.6 and undervolting by 50 mv. I also have a save battery life profile that drops it down to 1026 when the screen is off, it's charging, or battery is below 40%. Can you guys give me advice on settings to use to save battery life? I really like this ROM and kernel but I'm getting such terrible battery life. I think it's probably more user error than anything but maybe you guys could provide some tips.
Thanks in advance.

How recently did you switch to Beans and LK combo? I wouldn't base battery life off of the first day after a flash. I use the same combo, however I use the LK exp version. I would suggest changing your voltages to match begin at a lower mv. I have mine starting at 900 mv according to Imoseyon voltage chart.
http://rootzwiki.com/topic/31329-ke...nimalistic-kernel/page__st__1410#entry1042976
That said, I have my screen off max cpu speed at 486 so you could probably go lower. How's your signal at work as well?

Hey thanks alot for the response!! It's the third day of this ROM/Kernel combo. So I can really go as low as 486 when the screen is off? I figured it probably wouldn't be very stable if I dropped it that low. I've looked at the Rootzwiki thread you posted and have set all my voltage settings as follows for the last two days:
1900mhz-1250mv
1809mhz-1200mv
1720mhz-1200mv
1620mhz-1150mv
1512mhz-1100mv
1458mhz-100mv
1350mhz-1125mv
1242mhz-1125mv
1134mhz-1125mv
1026mhz-1125mv
and its 1125 mv the rest of the way down.
So basically I'm undervolted by about 50mv at the highest clock speeds, then gradually come down to about 25mv at the lower speeds.
I'm really scared to go much more than that for fear of causing instability. I would love to be able to undervolt by more if I knew for sure it wasn't going to make it unstable. What are your voltages at the highest clock speeds and the lowest? Can I undervolt it by more when I get down below 1026 mhz? I figured they were all set to 1150mv stock for a reason. Got any advice on that? I want to squeeze as much battery as possible..
Oh and my signal is perfect! I think it's even better than it was before. This Rom didn't come with a different radio too did it?
Thanks for the reply!!

I'm really scared to go much more than that for fear of causing instability. I would love to be able to undervolt by more if I knew for sure it wasn't going to make it unstable. What are your voltages at the highest clock speeds and the lowest? Can I undervolt it by more when I get down below 1026 mhz? I figured they were all set to 1150mv stock for a reason. Got any advice on that? I want to squeeze as much battery as possible..
Oh and my signal is perfect! I think it's even better than it was before. This Rom didn't come with a different radio too did it?
Thanks for the reply!!

I actually have my voltages set to exactly what Imoseyon has listed for the nominal cpu. As far as my screen off, I honestly just picked a low number and since I don't see lag I keep it there haha in addition, I use interactive governor which scales up the cpu once the screen comes on so it balances out either way.
To check which cpu type you have, do this. Details on what the cpu differences are included in the link as well. Matching your cpu type and adjusting your voltages may help extend your battery life but some say it is marginal.
No, your radio actually stays the same unless you manually flash a different one. I should also ask, what else do you have enabled? For example, in Maps/Settings, do you have everything disabled except "Enable Location History"?

Yeah i already did that to sort out what Cpu I have as well.
And I have limit background processes enabled in developer options, limit processes 4 at most. Also where exactly are the maps settings? I have GPS off and Google maps frozen by Titanium backup (except when I use it occasionally). I also have every other unnecessary app frozen. Like the Samsung keyboard (use swiftkey) the stock email app, etc.

Well it's under Location Settings but if you have Maps frozen until needed then it's an unnecessary step. You have done even more than I do or suggest haha I haven't frozen anything.
What would you say you're seeing as your average screen on time?
Sent from my SCH-I535 using xda app-developers app

Oh average screen on time is probably around 2.5 to 3 hours or so. Nothing crazy. I just wanna get my battery life back to before, where basically I could leave home fully charged and work a 10-12 hour day and come home with around 30% or so battery life. That's good enough for me.
So about these recommended voltages. I have the "fast" processor, should I just st the voltages for what he recommends? Are those recommended for bet battery life or best performance? I want to undervolt as much as possible without creating an unstable system or causing damage.
And can you help me understand the governor settings, my understanding is that "ondemand" activate both cores when needed, and interactivex is all the time? Is that roughly correct?

Okay nevermind about the governers. I read quite a bit more about them over the last hour and feel that I understand them at least a little bit better. hehe. So much to learn!! It seems InteractiveX is the obvious choice for performance AND battery. I'm still kinda unsure about how much undervolting I can really get away with though. I love how smooth everything runs when I'm overclocked, but i'm not sure it's worth it in terms of battery life (unless I'm playing a game, or flying my AR Drone). It seems there is still an advantage to be had by setting it to the normal clock speed (1512mhz) and then undervolting by just a bit. Might be able to squeeze just a tad more battery life out. It's still nice to have these things within my realm of control though. I understand why people find this so addicting now!

Yea flashing kernels and roms is very addicting. Since you have a fast cpu, you can actually UV much lower than I can with my nominal cpu. You can set your voltages to match Imoseyon's table and you'll be fine or maybe try lower. I know from experience that I can't UV lower than 900 mv without my phone immediately locking up lol You can even hold off on setting voltages at boot if you want to get a feel for performance while UV'ed.
I can't really speak on OC vs. regular clock battery life, I keep mine OC'ed at 1.62 ghz so I'd notice minor drops in battery life compared to say 1.8 ghz. I don't even have much need for that since its fast enough to me as is. I haven't noticed too much of a hit on battery, I still range between 2.5-4 hours screen on pending if I'm on LTE or wifi during that charge.
Also, if you want to try your hand at really digging into kernel settings then you should also check out the the Team Kernelizer's thread for KT747 kernel. Personally, I use LeanKernel cuz it works really good for me so I applied some settings from there but not everything was applicable. This thread has some really knowledgeable people in it. Definitely give KT747 a look, or any other kernel for that matter, and see which ones you like the best.

Yeah i think i may have had a bad battery. I checked and I know my phone is deep sleeping, but since adjusting my voltages and settings last night it'd definetely improving. I have my voltages set to 25mv under what is recommended on that chart down to 1.4 the in the lower clock settings o have it exactly at the recommended settings. Seems to work okay. I have set on boot enabled but i also have the stock voltage settings on my SD Just in case of a boot loop.

Does anyone have any suggestions? I really like this ROM and would prefer to keep it if possible but this battery life is terrible. Ant ideas on some measures I could take to try and improve it a bit?
I wiped cache partitions, davlik cache, and did factory reset before installing. I even do them twice just to be sure.
Would maybe wiping and re flashing the Rom help? I'm totally stumped here.
sent from my Galaxy S3 on beans 14 via tapatalk 2

I don't understand. I used cpu spy and i know phone is deep sleeping. I have set CPU to drop the clock speed when screens off.
Why the heck is it using so much battery? I'm dropping about 6-7% battery at idle. Somebody shed some insight.
