[Captivate General] tietherope:
How long were you running Continuum on your phone before you ran the test? If it were a few days the battery would be properly calibrated, where as changing roms daily can make the battery inconsistent. I know when I change roms it takes a few days to level out.
[Captivate General] chase10784:
I agree, time of day shouldnt have any affect.

I have money on cm7 to have worst battery life (from what i hear it hasnt been the best) followed by stock lol.
[Captivate General] ryude:
I noticed Precision is the only ROM you've tested that doesn't use the same kernel/modem as the others... I thought we were trying to make all the variables the same?
[Captivate General] jivy26:
Yea I ran it a few days before I ran the tests so probably so ill just rerun it again
[Captivate General] tietherope:
Sounds great. Thank you for the work you are putting in. You are saving a lot of people many hours worth of work.
[Captivate General] jivy26:
Some kernels and modems work better with other roms and the way it's built is the way I'm testing. The creators know best for there roms. If a certain rom and modem are consistently atop in my tests when I get done ill swap modem/kernel into roms without it and see if it effects that much.
[Captivate General] chase10784:
I think what is trying to be done is just changing the stock rom which includes whatever kernel and modem was used by the devs. Changing the kernel could lead to the results being affected for the rom because some roms wouldnt play nice with some kernels so just going with stock makes sure that the roms use what they were intended to use by the devs. does that sound about accurate?

Edit: jivy took the words out of my mouth lol.
[Captivate General] jivy26:
Very accurate some devs were concerned because certain kernels and modems didn't work well with there roms. So leaving the rom how it was cooked was easiest solution to allow us to see results how the dev wanted.
[Captivate General] ddoubt:
hey jivy26, I´m getting excellent battery life with Darkyy´s 9.3... you could test it out too!
[Captivate General] chase10784:
I think from what he told me his intention is to hit them all.
[Captivate General] avgjoegeek:
Still it would be great to use as a baseline to show how it stacks up to the other ROMS your testing.

Cool post btw - look fwd to how this turns out.
[Captivate General] ryude:
It seems to me these tests so far are inconclusive. No offense, but you could re-test every ROM and get different results.
[Captivate General] chase10784:
I agree that you may get different results if you retested but not incredibly different results for each rom. I think they would be close to what they got the first time but that difference wouldnt be significant.

Now a more precise form of measurement would be to cycle through each rom like 3 times and take the average of the 3 to be its time. but that would take FOREVER.
[Captivate General] jivy26:
I wouldn't say inconclusive, that's a bit drastic. I'm going to retest continuum and all my tests will be done shortly after flashing a rom to eliminate the askew results like I got with continuum. With precision and serendipity I flashed shortly before I ran the tests. So ensuring I do this for evey rom is vital. But aside from making that error I do everything exactly the same to keep it as precise as possible to give a baseline of roms battery performance, but is in no way a END ALL. Most basic users don't flash a different kernel or modem, which is why I'm testing how they were cooked.

If you want I'll give u the same movies I'm using program and all settings and you can give it a whirl and see what u get.
[Captivate General] diablo009:
+1

+1

I feel its good if a ROM is tested just once. Doing it a second would not produce too much variance in results, give or take 5%.

Also doing each ROM 3 times wouldn't be feasible with the number of ROMs being released everyday.
[Captivate General] chase10784:
VERY true....everyday there seems to be new updates or versions to roms, these devs are very dedicated so for that we thank you (tosh.o lol). thus the rom flashing addiction and i just started on the quest to find the best rom for myself.
[Captivate General] ryude:
In real-world use, Precision has always gotten the most battery life. I have done my own tests and they are repeatable. If you want your results to be meaningful they have to be repeatable and consistent.
[Captivate General] jivy26:
This isn't to put down any one Rom I've ran precision and gets great battery life, but there is no way to do the exact daily real world use. Well if you can use that big brain and script up something that constantly jumps to a different website every 10 seconds I'd roll with that bad boy. Just saying lol
[Captivate General] ryude:
Good idea...
[Captivate General] jivy26:
That a yes? Lol
[Captivate General] americasteam:
Great info. Thank you!
[Captivate General] xtremekilla09:
For some reason, I feel like I am waiting for my report card. Those were the days...lol
[Captivate General] jivy26:
I used to hate report cards lmao! Just flashed Firefly and off to "The Test" lol! Thank you, ryude and all the devs for your hard work ;)
[Captivate General] chase10784:
+1 to the devs

Eagerly awaiting the next "report card" lol.
[Captivate General] geokilla:
I think there's a flaw. With each ROM you're testing, the battery life is decreasing by over an hour with each ROM. You need to let the batterystats be calibrated correctly so it gives an accurate reading of the phone's battery life. Every time I flash a new ROM, I have to charge it a couple times to get an accurate reading. Sometimes if I don't calibrate or delete batterystats.bin, the phone will read that I have 5% battery life remaining, when in fact I have say 30% remaining. Last night it said I have 24% battery life remaining when in fact I had only 2% left!
[Captivate General] smanzor88:
AWESOME!! now this is the thread im talking about!!! its like you read my mind! Ive always wanted to flash a custom ROM but didnt want to give up battery life, because i would rather have better battery then a faster ROM.. but thank you for this! subscribed :)
[Captivate General] askpcguy:
Those were the days kids were left behind, lol!
[Captivate General] DreamingWillow:
YES! Thank you!

VERY MUCH SO looking forward to the results of your testing! Thank you so very much for doing this, it's much needed and appreciated. THANKS go to you!
[Captivate General] jivy26:
Just finished with Firefly and I think the only issue I had with my testing was the one time with Continuum where I used it for a few days before testing it as where with the others I just flashed set everything up and ran the tests. Either way it goes these results are pretty spot on to what I was expecting originally before I bonked the test for continuum lol.

edit for those who work for Honda: 5h17m for Firefly lol
[Captivate General] DRShockie:
i LIKE THIS KIND OF COMPARISON ....i FIND THE QUAD GOES HIGHER AFTER A SECOND RUN?
[Captivate General] shoman94:
Are you retesting continuum now?
[Captivate General] jivy26:
I will be testing it overnight gotta recharge lol. Yea the quad and linpack seem to jump around so I just do 3 times and average.
[Captivate General] di11igaf:
just something to note, just depending on the color fixes in said testing roms kernel is gonna make a pretty big difference. anything based on a speedmod kernel is gonna have a longer screen on time at the same % brightness vs a kernel with voodoo color. a speedmod kernel at 40% WILL be noticeably dimmer than a voodoo color kernel at 40%.

your really not even testing roms here, all the different roms with the same kernel are gonna be extremely close. theres just not much to actually do to a rom to kill/save battery, unless theres an app like the broken gallery. most i9000 roms are using the same wifi files, very similiar bases, differences in theme/framework/apks.

you can check this yourself by testing my rom with each version of my kernel. pretty much same kernel, 1 has hardcores screen adjustments, the other has voodoo color. guarantee you get two fairly different numbers.(note-this is only gonna affect screen on time, but thats the #1 battery hog so its kinda important.)

also, if you accidentally leave auto-rotation on on one and not the other, thats gonna make a pretty big difference. with auto rotation on, sensorserver_yamaha will constantly run, even with phone sitting flat, using anywhere from 3-8% cpu at any given time, usually staying around 3%. this completely goes away with auto-rotation OFF. so this will make a pretty big difference.
[Captivate General] jivy26:
For the voodoo.color and others similar thats how the rom was intended if it were cooked like that and I understand that might give a worse result than a rom without but thats the point to see which gets better battery life and that will affect it.

As for auto rotation I always turn it on that way I can have the video running full screen.

Ty for your rom btw love it
[Captivate General] chase10784:
Hmm, i wonder if the new JS7 builds of phoenix and twingerbread will give them an advantage in battery life...from what i hear JS7 is supposed to be slightly better with battery. I am not entire sure what is supposed to be improved from JS5 to JS7, if someone could inform me that would be great.
[Captivate General] Coak5:
From what I've heard so far, only battery life and speed (snappiness) is improved. Don't know how everything else is but if it's faster and saves more battery, that seems like a win to me.
[Captivate General] chase10784:
Those are also the two things I heard that have improved. I agree, those are two pretty important things to me too.
[Captivate General] jivy26:
Continuum results posted they were very askew originally. Onto cognition!
[Captivate General] xtremekilla09:
Nice! I feel like I got an A (for now..lol)
[Captivate General] di11igaf:
1) thank you

2) again, i think what your doing is great, i just dont wanna see any rom devs rom get a bad score based on the kernel.

if you REALLY want to test the actual roms battery life, make the kernel a constant. use the same kernel/modem for every test to take them out of the equation. that way your strictly testing the rom, and thats it.

and something people probably dont realize about that, all the improvements samsung probably made with battery and speed were most likely done in the js7 kernel. they most likely made some rfs improvements or something, but that matters 0% because we would not be using a js7 kernel or using rfs. the actual rom iteslf is probably almost identical to js5(i havent looked at it so i cant say for sure). just like jpu/x/y/js3/5- there almost identical between all 5. theres some small framework changes and js3 adds some stuff to services.jar that wont affect the average user
[Captivate General] jivy26:
Originally I had intended to keep the kernel constant, but a few pm's later some devs said the another kernel ran better for there rom. I'm actually gonna test Phoenix next to see how js7 performs results for it will be up in am. Almost done with cognition I think then charge up again.

Also later on when I get more results I can take lowest performer and give same kernel and modem as top performer and see how it runs. Just food for thought.
[Captivate General] jivy26:
Updated results for Cognition charging to full then Flashing Phoenix :o
[Captivate General] ryude:
Like for example, if you ran my rom with the kernel I supplied using the recommended clockspeed, voltage settings, lagfix, and i/o scheduler, you would get much better battery life. But, since it's only 20-30 minute difference now I don't care as much as I did when it seemed like a 3 hour difference lol.

I always got the best battery life with these settings:

- 600MHz clock speed

- -100mV to all steps

- ext2 lagfix

- noop or deadline scheduler

- JIT enabled with 32m heapsize

YMMV
[Captivate General] jivy26:
Lol at 20-30 minutes comment. I understand what you're saying, but uc/uv any rom will give it better results either way the disparity between roms is what I was originally expecting not the 2-3 hour's that made me poop my pants lol.
[Captivate General] ryude:
The 20-30 minute difference was because my rom uses a oc/uv kernel (that you didn't take advantage of) and the others don't, plus it's a different modem. Either way, not a big enough difference :)

[Captivate General] ryude:
I just remembered, suckerpunch also came with bfq i/o scheduler enabled by default, the speedmod comes with cfq enabled by default. Just another difference if you care.
[Captivate General] dizx:
Interesting that the JS5 ROMs are at the bottom of the list so far. Best battery life I've had was on Precision whether it was UV'd or not.
[Captivate General] bigsmitty64:
+1, I noticed that also. Can't Forget Dilli!
[Captivate General] dizx:
Can you add Dragon to be tested? Would like to see how an NKP5 based ROM fares.
[Captivate General] pizz0wn3d:
So this is where you've been hanging out Ryude... What ever happened to that update you were planning on releasing for us? :P

Or have you still not sold your Atrix to come back to the Captivate where you belong?

Herp derp Captivate XDA app.
[Captivate General] jetdite:
Could you add Andromenda to the list? I'm currently using it.
[Captivate General] jivy26:
Added Phoenix results as well as ROM requests.

@Ryude, I understand exactly what you mean and this is designed to run "Out of the box" which is why I haven't added all the tweaks you mentioned.
[Captivate General] redger725:
You forgot to update your chart to show the phoenix results.
[Captivate General] jivy26:
LMAO thought I posted it there you go!
[Captivate General] dizx:
@jivy26 Though there will be questions how you run these tests, I am sure we all appreciate your efforts. Someone has to do it! :-)
[Captivate General] jivy26:
Yeah I have been fielding them since I started lol. I listed the basics of how the tests are being run in the first post. I do the exact same steps everytime and place the phone in the exact same place in the house.
[Captivate General] dizx:
I know people have mentioned the kernels affecting the battery life, but I am keeping my eye on the base of these ROMs.
[Captivate General] onlyapilot:
Thanks a lot for doing this, it's a great idea and I very much like to see systematic approaches to these sorts of problems.

[Captivate General] jivy26:
Lol thank you I can say I am a flashing guru now and thank god for TiBu
[Captivate General] kingmurry:
wow thanks been waiting for somebody to do this , im glad firefly is at the top of the list that rom
[Captivate General] chase10784:
well seems like they are all almost identical with this test....
[Captivate General] ryude:
Funny thing is, I actually have new versions of both Torch and Precision but I am afraid to upload them since I don't have a captivate to test them on.
[Captivate General] dizx:
Post 'em. No guarantees, but I might take a shot at an updated Precision. I've got a jig. :)
[Captivate General] kimchi0400:
I'm more curious to see what kind of results we'd get with testing based on real-world usage, or at least taking an average of multiple results, but it's nice to see someone doing any sort of testing with regards to battery life.
[Captivate General] jivy26:
Yea I agree but I can't script to save my life and me using it throughout the day will not guarantee same exact usage each time. If you or someone you know have the time to build a script that will poll a different website every 10 seconds and let it be 10 of the same sites each time then I'll run it that way as well as my video streamed way.
[Captivate General] jivy26:
K did some digging and think I've found the closest way to generate stats based on real world results. Dolphin browser has a reload tab plugin so once I finish testing battery life with video steam I will test that way by setting it to reload xda.site every 15 seconds on data not wifi. Also if you have any roms you want tested request them by monday evening that way I can start wrapping this way of testing battery and get onto testing the other way.
[Captivate General] ryude:
Hope you have unlimited data plan :)
[Captivate General] jivy26:
Lol thankfully I do
[Captivate General] geokilla:
Just in case no one saw...
[Captivate General] ryude:
I am pretty sure he is not testing battery %, but battery voltage. Every ROM is charged to absolute full voltage and drained to the same voltage. If not, then he is doing it wrong.

Example

Full charge: 4300mV

Drained charge: 2700mV

[Captivate General] likiud:
Still testing Paragon? I'm very anxious to see the results because I'm getting good battery life from that
[Captivate General] mirotvorets:
it's interesting to view test result of stock 2.1.

it's seems to me on stock 2.1 battery live longer then on froyo.

by the way, we has no test algorithm yet how to correctly test battery life in different state of our phone and how to correctly compare results.

i've written a small article with aim to develop algorithm of compare battery drain on different ROMs. my native language is Russian, so article in Russian too :)

i hope to find some time in the future to translate the article in English, now you can read it via online translate here 4pda.ru/forum/index.php?showtopic=224077 :)

[Captivate General] psycho2097:
I really want to know the results for twingerbread, since they claim the longest battery life(i m juz a noob, btw..)....I ve had excellent battery with both twingy n darky..currently on darky, Suckerpunch 56 @ 1.3Ghz.
[Captivate General] chasesavestheday:
please add torch 1.5 to your list.

its no longer being developed and there is a 2.0 version. ive never seen battery life like torch 1.5 built on at&t uckb1 froyo.
[Captivate General] ryude:
I don't recommend torch, I have found a bug which prevents audio output through the 3.5mm jack.
[Captivate General] jivy26:

Is there any good external portable battery or charger?
[Desire HD Accessories] paul c:
Ive got one of these http://www.amazon.co.uk/New-Trent-Dual-port-IMP50D-Blackberry/dp/B004AM1OK4/ref=pd_cp_ce_1

5000mah: does what it's meant to do, you can charge any electronic device with it (that you already charge from a USB port).

It comes with a nice coiled cable which has a USB connector on one end, and 2 adaptors: mini- and micro-usb.

So you can use it for charging the external battery itself, and for charging the HD from the external battery. You can also use your own USB cables if you want.

Amazon also have an 11,000mah model!

They're much cheaper on Amazon than with the manufacturers, though you may find them even cheaper o ebay or similar. This brand had a lot of positive reviews on Amazon, and it seemed discounted, so I bought it from there.
[Desire HD Accessories] panart:
I use Zagg Sparq

Specs:

6,000 mAh Lithium Polymer

Has the power to charge most smart phones four times

4 yellow lights indicate power level, 25%-50%-75%-100%

Has the ability to charge multiple USB devices simultaneously
[Desire HD Accessories] paul c:
I paid GBP21.95 for the New Trent 5000mah pack I mentioned in post #2.

It is now being sold on Amazon at GBP29.99 :eek:

still a good price though, if you compare it to an OEM battery

[Galaxy Tab General] htung00:
Well I've doing alot of messing about with kernels and and custom roms and now my videos no longer sync with audio.

Somewhere in bewteen stock and my current settings my video stopped syncing with thier audio.

- When I dicovered this I was using the latest overcome rom with it's kernel.

- I then tried reverting back to ROTO JME v4 using a previous back up: no change

- then going back to modaco's ext4 kernel: no change either

- Finally tried doing a full re-install of overcome and no change there too

I've been testing with .h264 encoded files on both stock player and Mvideoplayer which previously played the files fine.

Anyone have any idea where I've stuffed up and can offer some advice?

edit: tested using rock player lite, files play fine under normal settings but after switching to hardware decoding i get the same audio sync problems. I hope this narrows down my problem.

edit 2: just tried reflashing roto jme v4 full clean install and also no go

I just got the Inspire yesterday, coming from a Captivate. I am running the latest version of Android Revolution, and everything seemed to be working. But when I got home, I found that my Exchange account won't sync when I am connected to wifi. As soon as I disconnect and try to sync when connected to 3G, works again.
