new test done...see first post...i add this first result test of ftb09 from twrock BUT with some reserve(not sure at all i have done things correctly or if there is something wrong) so for the moment score is 334...will redo the test :huh:

i have done new test of ftb rom the score is worst:280 :blink:

edit it might because of frill cpu...first time it was set(cpu 528) second time it was off...

Interesting how Twrock could find FTB the best battery saver then?...

hi.i think twrock would be interested by this topic...may be he could make better research about saving battery...

[Guest twrock]

Interesting how Twrock could find FTB the best battery saver then?...

Sorry, but that is a misunderstanding. I have not made that claim.

I have not maintained that FTB has the highest battery savings compared to these latest roms (the roms you and dr.flo have created over the past months of development). I have said in the past that FTB has better battery life than TXG (Tom's rom base). But that is before I found that turning off screen rotation has such a large influence on the CPU vacilation on my phone using 2.2 roms. (And I have not used TXG for any length of time in many, many months, so I have no idea how that change would have affect battery life in the TXG rom.)

But more recently (and more importantly), I also have said that the current CM6 (dr.flo's rom base) has better battery life than FTB and CM7.2. So without doing any empirical testing myself, only based on my own observations and my own usage pattern, I reached the same conclusions of the testing here. (I have nothing to say about UM840, since I have not ever used it beyond installing to find out if it was possibly a rom I wanted to work on creating a mod for my own use; I know nothing about its battery life, but if it is 10% higher, then I have at least a bit more interest.) ;)

Older posts written prior to the arrival of your and dr.flo's roms should not be used as the basis for what are my conclusions now. A lot has changed since the days when I decided to use FTB over TXG primarily because of my experiences with battery life. And many people had the same conclusions as I did when comparing those two roms. I am now trying very hard to make Styx my daily use rom, since I prefer it over stock Froyo. It is nice to see that desalesouche's testing reveals that there is a good basis for my preference of Styx over FTB. :)

I hope that clarifies things.

hi.i think twrock would be interested by this topic...may be he could make better research about saving battery...

No, I don't have any better way to test battery use. I think your testing has a very good basis for comparison. It is one phone, using one battery, with as much as possible using the same settings (assuming even things like screen rotation settings are the same, etc.). That sounds like a very good way to do the testing.

However, it could be that a different set of settings will reveal different rankings. There are a lot of variables that could be affecting battery life. But in general, I think this is a good way to test this. Thanks for doing all that work and sharing the results with everyone.

[Guest pier11]

Thanks. Twrock, for your comments.

Looks like we are all on the same page now.

And I will throw off my head thought that FTB can offer better battery life :)

Based on desalesouche's findings with .32 based roms, I concluded for myself on the other thread that:

- Froyo is 20% more energy efficient than gingerbread (at least with it's native .32 kernel) 431 vs. 363 for CM, 474 vs. 398 for stock;

- Huawei's roms do 10% better to manage power than our cmX - 474 vs. 431 for froyo, 398 vs. 363 for gingerbread.

- Difference between first and last is 30% (stock froyo vs. cm7.2)

so :unsure: .i might have to redo all the test... i will redo them all... not because of different setting while testing( always same settings) but because of how i charge the battery.

i explain what i mean: i could notice difference while testing twice the same rom.sometimes quite large difference...so i realise that i was not charging battery the same way each time..according to this from: http://android.modaco.com/topic/347111-quality-battery/

To get the best out of your battery please follow the instructions below:1) When you receive your new battery, take it out of its packaging and insert it into your electronic device. Turn your device on and drain your battery until you’re left with 1 bar of power. Then charge your device for a minimum period of 12 hours. Your first charge cycle is very important, do not charge it before it is down to 1 bar.

2) After you have completed the initial charge, your battery should only be recharged once you drain it down to 1 bar of power and should be recharged for a minimum period of 6 hours for the battery to reach its full capacity. Ignore the phone telling you that the battery is full—this is normal but is not accurate.

3) Make sure that the contacts are clean.

so i will be keeping the battery charging 1 hour after phone telling battery is charged. and then do test...like that all the test would be made in same conditions...cos i thought that it might be the cause of difference in result after testing twice. hope people would understand what i mean...

for info with de2.1 mod00 i had 249 score and then 324...so from where come the difference?..i am suspecting the way i am charging battery...

@ dr.flo/pier11/twrock: do you agree my point of view?

@ dr.flo/pier11/twrock: do you agree my point of view?

From my point of view, accurate/reliable results from testing can only happen if the steps before each test are precisely the same. And of course all other possible variables (settings, etc.) must also be precisely the same. So if you didn't charge the battery exactly the same before each test, then the results won't be reliable.

Many people who installed the de2.1 rom reported very good battery life, so I don't know why it would be so low in your tests. RBM2 was praised as being very good, even better than de2.1 and uk2.1 from 2011 (and that is why I chose RBM2 as the base for FTB).

But in the end, one person running the tests is never going to be "conclusive". This testing would need to be repeated by quite a few people before there would be consensus. However, since your original numbers agreed with my own "feelings" about the roms I used, I found them very believable. But who can trust my "feelings"? :lol:

hi :) .i think that the de2.1 might have been falsed by the wifi.if i remenber well it seem that antutu tester is turning wifi on.generally i turn it off .but with that rom i couldn't do it.so may be i should redo the test for all these rom with exactely same settings and battery charge...+wifi on?

[Guest rhen]

How do you turn the wifi off while running the test?

on um840 rom, antutu tester turn it on and if I go to the quick settings and turning offthe wifi, the test stop.

Wifi is a HUGE drain on batteries. Yes, it will have a significant influence and render the comparison invalid.

[Guest desalesouche]

i usually turn it off from status bar... but on de2.1 rom there is not that fonction in status bar...is there a status bar anyway in de2.1? the solution would be to add that fonction in rom where status bar is missing; so we can turn it off.

how to add status bar please?

so we can turn it off and make test.

the other solution would be to do test with wifi on ..like that test would be done i a similar way....

i just wake up so i might say idiot things...:blink:

what do you think if redo test with wifi on ?

like that all the test would be the same ...with same time about charging battery...

[Guest pier11]

I would agree. Wifi is a significant contributor to battery life.

[Guest twrock]

Also consider that with wifi on or a data connection on, you have to make sure that no data is being transferred or sychronization is happening. Otherwise you are again not controlling all the variables to make them the same for each rom.

I would think that less things turned on is better than more things turned on, but whatever you do, you have to have all things equal if you really want a comparison.

(Hmm, this is getting more complicated by the minute!)

[Guest rhen]

Put it in airplane mode and turn off the screen rotation. But with this setup, we can't determine how different kernels handle the radio/wifi. It will only show, how CPU drain battery.

So I think better setup is phone connected to 3G, keep wifi on, turn off auto rotation and syncronization.

ok we will do that way.but cpu still @528 and don't forget about the battery charge: i mean would you prefer to run the test as soon as the phone is telling the battery is charged or let it charge one hour more (after phone tell battery charged)?

i will redo all the test but we have to do them in the same way... so with our result in same condition it would better i think.

I think 30 minutes after the phone tells it's fully charged, enough.

I'll do one test today with um840 rom.

ok for 30mn about battery charge...:) don't forget brightness 100/100... we need to test all these above rom each so we would have double result in same condition. will do um840 in a while.

i don't know why i have a problem to test um840 rom with antutu tester...it is always stopping after a few minuts ...:angry:

any idea someone? thx

will soon update first post with new setting results.(just 2 at the moment that i have problem with um840;otherwise i would have 3 result)

I had the same problem yesterday.

But I've done two test before. Maybe something changed in the updated version of antutu tester.

[Guest desalesouche]

first post updated .i keep on testing :)

[Guest didije]

To be honest, I was surprized when I first saw your old test results. Pier's cm7.2 has the best battery life I've seen. And I tried almost every rom from this forum. So I'm glad to see that the second test score was that high. For me, it really has the best battery life.
