[Q] CM 7.1 Stable vs Stock JVx Battery life

After using Samsung stock ROMs for over a year I finally switched to CM7.1(Stable) last week. But the battery life I'm getting now is not as good what I used to get with Samsung stock ROMs. With JVT I easily got 24hrs, but now I cant go beyond 15hrs with same usage patterns (3G during day and WiFi at night, few short calls and around 50 SMSs, with a bit of web browsing and some online audio streaming). Did anyone else notice a similar battery life drop going from a recent stock ROM to CM7.1 ?

I ran the CM7 nightlies until recently and came back to JVT because of battery life and the hello hello bug. I use my phone as a music player for most of the day and find that stock ROMs hardly deplete the battery at all, with CM7 I was getting the same sort of life as you.

For me, CM 7.1 Stable drains battery a lot. I've changed to JVP modem and it seems to be a bit longer, maybe I'll try with Fugu kernel.

Looks like I'll be going back to JVT. Idling battery drain is way too much. For example I charged it around 8 last night and by 12 noon today, battery is down to 45% mostly just idling and few texts. This is as bad as original eclair release came with the phone.

I personaly dont find there to be a huge difference but i am on Bell which is HSPA only (3G all the time)
i find i always have to recharge by 4 pm (8 am wake up) but i am a heavy user. I am waiting for my extended battery so i can make it through a day.

What was the last stock ROM you used ? I used to get similar battery life with earlier ROMs, sometimes I had to charge it twice in a day depending on usage. But with recent ROMs (2.3.3 and up), I ever hardly charged it twice, despite very heavy use (more than an hour of calling , GSM/VOIP, about an hour of internet audio streaming etc..). IMO stock ROMs are really good at idle power consumption, I have managed to get 2 days with light use, a full day with moderate use and more than 10hrs with heavy use.
EDIT : CM7 is smoother and quicker; I also like the customizability. I’ll again give it a try when ICS comes out , but till then I'm back to Samsung Stock, because poor battery life simply kills the experience for me. Perhaps I can squeeze couple of hours more with some tweaks, but I doubt it'll be as good as JVT.

I myself have come back to 2.3.5 xxjvt cos coming from cm7.1 and darky 10.2 final..i should say stock rom can have a standby time of more than 24hours believe that..otherwise ics might have a lot more to over than gingerbread

I hope when ics is released by cyogenmod battery life gets better this is why ive not updated to 7.1

Hello U all.
Can somebody give me a link to the CM7.1 stable for i9000?
Thank you.

Best rom for Battery?

Hey guys. I only want to ask which rom do you think is the bettest for battery life.
Thanks.

My suggestion would be stock gingerbread with speedmod kernel k2-12, i used to get around 4 days with normal use.

That sounds nice. Do you have heavy use of yout phone? Or only deep sleep all the time?
Sent from my GT-N7000 using xda premium

I use it for playing games, little music, calls and messaging. Sometimes connect to Wi-fi. With the same in ICS i get around 2 days.

okay thank you i´ll try. :fingers-crossed:

to set expectations straight, expect thought about 4.5 hours nonstop usage on gb with speedmod kernel.
4 hours on ics with speedmod
alk stock dont expect more then 3 to 3.5 hours.
you only get 2 days if you dont synch, barely use phone and are in good reception area with data switched off always.
Note general tips which can be found in the 10000plus threads about battery drain and how to analyse deepsleep issues

I don't know whether you like gingerbread roms or not , but till date the rom with which I got maximum battery backup with modeate to heavy usage was CheckRom Revo HD V6. This rom never lags , best battery life , and good speed .
If you are Gingerbread hater and ICS lover , then you can try Rocketrom v7( very good battery life with the included kernel , and would be much better with Speedmod Kernel (latest version) ). And then you have CleaNote V2.30 ( V3.0 has bluetooth glitches but its faster , if you are bluetooth user i would suggest you to stick with V2.30 ) , I personally love CleaNote because it has stock look and very fluidic :good: and as the tagline says 'You dont want any theme forced down to your throat '. KingDroid are good at speed but many have reported few glitches with it , you may try it if you like ( I dont like KingDroid , its sth personal ). If you hate Samsung's bloatware then we have Cassie's XtraLite rom for your rescue :cyclops:. Its a good rom too .
Well finally to end , I use cyanogenmod 9 and i update it everyday and with each update it gets more fluid and responsive, fast , smooth . i just love cyanogenmod9 ( waiting for cm10 ).
ParanoidAndroid are for ppl who love fun , who want to showoff their phone , the ability of their phone , the sweet hybrid interface of their phone , its for geeks :-0 .
Make a choice or try all of them :good::good:

I am using CLASSIC V1+15 toggle with MOD V1 which is ICS 4.0.4, and I also updated kernel to chainfire LRG, which is more stable and smooth, battery life is excellent comparatively to all other ROMs so far.
Which is around 4% drain per hour, I have (facebook, wechat, LINE, mitalk, whatsapp, email, exchange service, maps, mixed chinese input, make your own clock) running and leaving it on idle.

For the past 2 years of beeing a S galaxy user, I've quite looked for best battery life at top performance. Most of the time, battery life is no longer measured in "days" of usage , like we used to do with our Nokia phones. Nowadays, you ten to look at display (screen on) time , CPU profiles, and also connectivity patterns.
You can think of battery life as a factor of the above mentioned, however I think that display time is the most important parameter related to battery life. CPU profiles, connectivity, tend to work only when you have your screen on, and from my experience, you tend not to extend your usage time by more than 10-20%.
So as a conclusion, I did not expect a specific rom / kernel configuration to offer more "screen on" time but to offer a more faster way to do my tasks therefore I did more tasks in almost the same display time.
At the end of the day, it is more important how you USE your device rather than finding a "magical" combination that will increase your battery life.

KID + SpeedMod

+1 for GB (i was using checkrom but i'm sure any gb rom will give similar effects) with Speedmod.
If you make setcpu to 200mhz on screen off, i find it uses almost no power at all when it's on standby.
Like it was on 77% when i went to bed.
Woke up in the morning and it was on 78% (i was like lolwut).
Yay for setcpu.
But seriously though, any GB rom will give you considerably more battery life than any ics rom.

I bet this is the best custom rom on battery savings, try it you will not regret it. http://forum.xda-developers.com/showthread.php?t=1722038

Best ROM to make battery last longer

Which ROM (including the official ones) is the best regarding the duration of the battery?
And another thing on this matter, I have read about battery calibration many times in this forum, but I noticed that was a not an unique answer. Does it really work or it doesn't affect at all the performance of the battery?
thank you

I tried them, and it seems to me that power draining was the same as with stock rom 2.2
I tried a nightly cyanogen mod ( cm-7-20120701-NIGHTLY-p970 ) , and battery last a much more time, but this rom is not stable enough.
Everybody is awaiting here for ICS rom from LG and hoping that battery draining would be reduced.

Interesting, on a stock 2.2 my Black needed daily charging and just for the night alone drained about 20% of a battery. Since I'm on Zeus, my phone can last 3-4 days (same usage as on stock) and uses about 3-4% of battery in the night :good:.

I installed last version of zeus ( v6.37) yesterday and leaved my LG OB unplugged the whole night : this morning, batterie was about 50%
Did you changed some tweak with zeus tweak tool ? ( I have changed nothing ).

I also wonder how do people get so good battery with Zeus v6.37 and such a low battery drain during the night, have you touched at something in ZeusTweaker since you installed it?
And another question: I didn't touch anything but I see that many people talk about DVFS, what is it actually and what is more recommend: to enable or disable it?

Well i have Zeus v6.27 and even didn´t feel the urge to update it as battery lasts for like 3 days, never had a SoD, hes fast, so only have to say good things about it.

Stock V20s with diana kernel.... its best.

Im using the Cici ROM Mokee Port based on CM7 and my battery will last one day only, I like it because of the beautiful interface but the battery sucks. I also tried Optimus Max Rom V2, battery lasts a bit longer but still not good. I havent tried Zeus yet but maybe il try using it and see how the battery goes.

ive always gotten the best battery life from zeus.... and also lemmings is coming in 2nd for me

Marvel rom is the best rom for high battery because the battery usage is almost none when the phone is ideal
My phone battery gets reduced only by 2-3% overnight.

I've tried alot of ROM's, and I think MIUI is the best for low battery consumption.

Supressed ROM V7, is the best for battery life.

so the conclusion is which rom are the best ?

From all the posts the conslusion is only one: all of them lol.

The best rom for battery life is the one that's switched off..... I can get two weeks off a single charge.....
just sayin...

fact 2.2 is very good if you mean battery drain, but 2.3 is better as system and in my opinion better choice is Optimus Max , cause he based on stock rom. I use it daily long time. I used many roms and I still prefere Optimus max . My battery keep live about two days in normal using ( many time in net ) - but sometimes it is one day . But on this rom I have not any suprises.

[Q] Jb to Gb, really tired of battery drain.

Hi, friends, yes i have this question because i´m really tired of my battery duration.
I used gb for a long time, about 8 months, and im resistive to go to ics or jb because in all threat appears the battery duration problem.
i dont know if really normal but with the same use of the phone in gb i come aprox to 20:00hs at night with at least 20% of battery left
and in jb i can´t pass the 19:00hs with the phone on (0% of batt).
And by the other way, after try for a month ics, and for other month jb, i think that the better things comes with it (that i dont really think is so mutch) dont compare with no battery duration. So i have a "better operative sistem" but my phone is off becouse of battery!!! jejeje
Well, my question is, to go back to GB, what must i do?
Just usuall wipes and flash??? by cwm or odin? or must be careful with something more?
Thanks!! and sorry but me english

Best and easiest way is to flash GB ROM package with PC Odin. Just select PDA file and hit start, nothing more.
You could also try staying on JB and trying a different kernel - or give CM10.1 a try, it's Android 4.2.1 with excellent battery life.

Last chance....
for my understand, i think there are 2 only differents kernels to try, stock and philz, inst it?
I´m using this rom:
[ROM][4.1.2 JB]Ultimate N7000 XXLSC JellyBean 4.1.2 v5.1 | OTA Available | 16/12/2012
it has this kernel:
NEW Philz Safe Kernel 3.73 for XXLSC and New CWM Touch 6.0.1.9 with exFAT Suppor
What other kernel then can i try?
And cm roms has missing the s apps, isnt it?
Regards..

After 8 months of use, the battery capacity is reduced noticeably. I just got a new battery for my note, and battery time increased substantially. Now I can actually use my phone and not worry about charging two-three times during the day.

Yeap, may be you are right, the battery life is gone worst in time by the naturally use, but one day i have 24hrs battery life time with gb and the next day i get 15hrs with ics...

[Q] JB vs ICS vs GB for battery life

Is there really any deference between android versions in battery life?
And in your opinion what is the best ROM for battery life at all (including GB)?

Well everyone uses their own phone accordingly. I currently use AOKP ROM. I do not have a data plan. If i use my phone only for calls or messages, i cant last thru 2-3 days. If i play games or whatever, then a single full charge only gets me through 1 day.
Battery Life is very dependant on how you use your phone so there really is not a best ROM for battery life

I meant that for the same usage which ROM (or android version) gives better battery life?

hmmm... I guess the you get best on CM7, which is Gingerbread.

I used lacoste 4.1.2 jellybean Rom . I have about 1-2 days on WiFi and average use . It can be considered as a battery saving Rom . Have not tested out other jellybean Rom yet besides that

Afaik, most battery friendly ROM is CM7 nightly #146 (GB ROM). Somebody recently posted download link for it. If you can't find it, download one of these, it will do the job. In general, avoid Sense ROMs if you need good battery life.

Addy

GB 3 Days
ICS 2 Days
With normal use

i think the best battery life is for gingerbread.

Gingerbread? mmm
with my phone, I had a quite good feeling about Jeally bean.. if you use a lot of data/3G traffic, gingerbread is not the best
