Phones back, but CBA testing the rest, sicking with MIUI and ICS builds

First, a description of what is going to happen in this thread. I am going to be running a wide variety of roms (see list below). Running it for one full charge on my usage.

My Usage

I would class myself as being a medium user. I rarely use games, but use the internet a lot. I check XDA, every half hour or so, email in on constant sync, checking every minute or so. WiFi and 3G are always on.

**NOTE**

I cannot guarantee the exact same usage every day, this is a rough guide. Allow 2 hours leeway on each rom.

This is only a rough guide, to see whether some rom makers claims of amazing battery life are true. I will also screenshot the battery usage to show any battery draining apps.

Rom List

Click the rom name to view the post with stats, links to the rom thread are at the top of the stats post.

---MIUI---

---Cyanogenmod---

---Dev-Null---

---Villain Rom---

---Cognition S2---

---Lite'ning---

---LeoMar75 Rom Revolution---

---Solar Flare---

---Sensation by Crysis---

---Stock KF3---

---Stock KG6---
​

List will be updated as I test more, but in theory, if this forum is arranged correctly, any not in the Origional Android Development section would probably have the same battery life.

CURRENT ROM IN TESTING: Lite'ning

Summary of findings

So far I have only tested the AOSP roms, and well, whilst officially CM7 lasted the longest, it also had the lowest screen on time, and dev-null, which lasted the shortest amount of time, had the longest screen on time. In summary for these, I would say there isn't really a difference in battery.

The big comparison will be between AOSP, Samsung based and Stock. I honestly don't think I'll find any difference between any samsung based deodexed roms, origional or not. As they are going to have the exact same core to them, if after testing 3, they have simmilar battery, I will skip the others to test stock, as this is better for the comparisons. I will test them again at a later date.

interesting topic. I think what may also be useful is to display the screen on time for each rom you test as this is probably what determines battery life the most IMO.
[Galaxy S II General] tshoulihane:
Please repeat at least a few of the tests, so it is possible to infer the variance of your measurement process.
[Galaxy S II General] commodoor:
It looks very interesting. It will be nice to see something like this. Good Luck with testing
[Galaxy S II General] dh2311:
I'm going to give miui a pretest after I've done the rest because cyanogenmod is lasting a lot longer, after 1 day 14 hours I still have 30% left

Will repeat tests once all are done

Look forward to this, i have tested battery life twice on Cognition 1.15 - 1.20 and 1.30, version 1.15 has the best battery life i achieved almost 29 hours, 1.20 comes in next almost 27 hours, 1.30 was disappointing i cant remember what (check the thread) but was nowhere as good as the other versions.

I have also just tested [ROM][03/08/2011][XXKG5] stock odexed + APM + NINPHETAMINE kernel 2.0.4_BLN ready by Sicopat and it has come in at an impressive enough 26 hours or thereabouts

Anyway ill keep an eye on this thread :)
[Galaxy S II General] liuwenaz:
can't wait to see all the results, very interesting topic.

Battery life is the only thing I am worried about.
[Galaxy S II General] gaui:
Great thread! Can't wait to see the results, although I would have made the tests without Juice Defender.

Also, what kernel are you using?
[Galaxy S II General] dh2311:
I use whatever kernel is bundled with the rom. And it shouldn't effect it because it uses the same settings on all roms.

Any extra Apps apart from juice defender and xda app?
[Galaxy S II General] dh2311:
K9 mail is searching every 15 minutes. Then the odd occasional Facebook and skype. Also I check engadget once or twice a day. Then theres the occasional web browsing, which is more if I spend a day away from a computer.

I don't use many apps, but the ones I have I use a lot.

So far its not looking good for dev-null. Its draining battery like a sink. Loosing 1% a minute when active.

EDIT:MUST BE A BATTERY METER BUG, MUCH BETTER NOW.

This is the ROM I am using, and it's quite good.. like to see how it compares with others.

[Galaxy S II General] ziTney:
Very interesting thread bro! This is going to be very helpful! Thanks for effort!

When you're going to test the Lite'ning ROM v5.0,

would you mind testing the ninphetamine kernel?

I think that like the half of the people who are using this ROM, flashed the ninphetamine kernel straight away(instead of using the Speed MOD kernel)!

[Galaxy S II General] Ghazkul:
Great thread, gona sub to it :)

As mentioned before, a screenie on the actual graph and on display info would be sweet!!, Could you also post what kernel was used on each Rom ? Reason I am asking is that some roms don't install a kernel so you are left with the previous Roms kernel!!
[Galaxy S II General] manbearpig86:
gr8 thread mate.. Waiting for the final report :)
[Galaxy S II General] dh2311:
Will do a test once all of the others are done (2 weeks ish probably)

Sorry, for the basis of this I am going to use the kernel on the ROM, because with different combinations you get different, battery life. May do a test of both (don't know yet).

I want this thread to be a guide so people can see what ROM they can download and flash with no messing (for that I should probably not use Juice Defender, but I need my phone to last me throughout the day and without it would be on low battery by the morning and it would be dead whilst im out.)

I am screenshoting all of the graphs already (or do you mean another graph:confused::confused:)

If the rom isn't bundled with a kernel I'll use ninphetamines kernel (because its plain awesome.)

And an update, dev null is about to die, but it could beat CM by half an hour, might make 2 days?? Battery meter is really off though, probably because i didn't reset battery stats. It drained from 100-80 in about 2 hours. But then it stuck on 8% for about 9 hours, whilst I was using aswell, not whilst I was asleep. After this I am re-testing new MIUI and will record screen on time (which will also be WiFi and 3G on time because of J.D).

This is now my favorite thread on XDA.

I think it'll be more accurate like that.

It's simple enough. First 3 are aosp. Rest are sammy.

[Galaxy S II General] mib1800:
Is there really a concern about high Android OS percentage? Firstly does anyone understand what the percentage in the battery usage really mean? If my phone is on standby (with data off), it drops about 0.4% per hour. But Android OS percentage is still high (40%+). I know if the phone is used (i.e. screen is on), battery drops 15% per hour. So it doesnt make sense at ALL that Android OS percentage is more than the screen percentage. (i.e. if the screen is on 1 hr it is equivalent to 30 hrs standby)
[Galaxy S II General] Fruktsallad:
I agree, that really is strange! After a day of usage, I regularly have Android OS usage corresponding to at least an hour of screen-on-time! Also, look at the tests in this thread comparing cm7 to MIUI. MIUI has vastly more AOS usage, but only marginally worse (within error margins) battery life. Are we missing something here?
[Galaxy S II General] Jeremy:
Please do not take the percentage too much into consideration. What is more important is the usage time.

Usage time is a better indicator of battery drainage.
[Galaxy S II General] comnam90:
anymore updates?
[Galaxy S II General] mib1800:
What is the "normal" usage? For me, Android OS usage time is about 10% of total uptime.
[Galaxy S II General] amiWul:
any updates?
[Galaxy S II General] iwang:
Freezing all bloatwares, my current usage averaged about 10% /hour..but the phone is brand new and I am on my first charge so things will get better.
[Galaxy S II General] flute:
+ 1

the screen is very important to determine real results
[Galaxy S II General] eybee1970:
to determine real and most of all COMPARABLE results would mean to use the phone the same way on the same places! with every ROM....reception is an important part - you might have better reception in you flat than on your working side for example...bad reception drains battery A LOT!!!
[Galaxy S II General] iwang:
Freezing those bloatwares alone take down my aos usage from 40 % to 8%..

Just wondering if juice defender does improve battery performance?

Yes, masisvely. Well 12-15 hours extra

[Galaxy S II General] imolared333:
the problem I find with our phone is that the super amoled takes way too much power. When phone is sleep, battery is okay, no drain at all...maybe 2-3% an hour. But when we actually use our phones, it drains so fast...I am not even mentioning playing games. Just simply launcher actions...anyone has the same impression?
[Galaxy S II General] Tinderbox (UK):
The display in the S2 is supposed to use 18% less power than the one in S1 , you would not really believe it would you, I suppose it`s the price we pay for such a beutiful display.
[Galaxy S II General] comnam90:
Yeah Im finding the SGS2 to have a way worse battery life than my old SGS ever had. My GF has it now and she gets 2-3 days battery on it, im lucky to get 1.5days
[Galaxy S II General] m2smoe:
Most ROM developers have stated that to accurately get an idea of a ROM's battery life, you have to charge/use up the battery at least 3 times.

Have you done this for these tests? Because if you haven't, those numbers don't really mean anything
[Galaxy S II General] comnam90:
you realise how long the tests would take then right?
[Galaxy S II General] m2smoe:
I do, but they would be accurate, which is the whole point of doing tests in the first place no? lol...
[Galaxy S II General] dh2311:
Honestly, that makes no sense. So long as the phone gets fully charged and calibrated. It will give accurate results. The 3 charges is probably due to random drain, from the phone not charging fully, which I have had on roms before. If it gets battery stats removed and left on charge for a while after it says 100%. I have had this before and when I get it I recharge the phone and retest. I'm on my 3rd charge with villain because of random drain.
