[Q] CM 7.1 Stable vs Stock JVx Battery life - Galaxy S I9000 Q&A, Help & Troubleshooting

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
Sent from my GT-I9000 using XDA App

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.

[Q] Gingerbread Rom with best Battery Life?

Hey guys, I hope I can get a few recommendations regarding Gingerbread Roms with gooooood battery life.... Currently I am running on MIUI mcgv.3 or something and the battery drain is just pissing me off....
I looked through the Rom list too but none stated how the battery life was on them..
Also I would like to have the ROM as minimal as possible, just all the tweaks (dont really care about themes, roms or unlocking screens)
So guys, any help and recommendation is appreciated ))
thanks a lot!!!
Best battery on a Gingerbread ROM I found using Criseklo v56.
Newer versions didnt last that long. Search in google Criskelo v56. I can get easily 40+ hours on that.
im using darky's 10.1 and the max i managed was 1d 20hours with 3g on like 3 hours
alright, thanks guys, I will check em both out )
FuguMod + Insanity Rom. 2+ days easy
I've gone from simply honey to darkys 10.1 and I could get more use out of simply honey. Seemed to have less glitches too.
I think GingerCriskeloV66 is also good !!
try it >>
I'm using MIUI 5.31. Left my Phone on for the night with Data + wifi on.
It went from 100% (which is fake. It's actually 98%) to 92%. That's pretty cool for an almost 10 hours sleep. Especially for this ROM which used to be a battery hogger! But now I love it =)
I'm on stock JVO + CF-root. Flashed another modem and a wifi driver from Latest BCM4329 (WiFi) driver for Gingerbread. Getting about 4 days on light usage with wifi, GPS, data sync on all the time. I have 1% battery drain over 2-3h on standby.
Iám on Simply Honey 3.5 Revolution! 1day 20hour with 1500mAh Battery!

Rom with the best battery life

I don't know If this thread has already been created if so please direct me to that thread.
So I used to think CM6 had the best battery life so I flashed 6.1.0 but not much battery life change so im starting to think that maybe it was actually cm 6.0.0 that had best battery life but im unable to find it so I can test it. So im here asking you all what Rom has brought you the best battery life to your cdma hero no matter if its 2.2 or 2.3

I would like to know what's your measure of "best" battery life?

My measure of best battery life is not losing 10% of my batery life doing nothing. I remember when my battery would be be at 40% I go to sleep wake up and its about 30%, now its dead by the time I wake up

don't need to flash the kernel since it's already in the rom. Just do a full wipe and bam ! I'm actually trying the latest one (june-08) but the june 4 version gave me that 15 hour
personally i have found that the rom you choose itself doesnt really matter, its more about your personal usage, i.e what apps u have running, cpu settings, etc. i usually get around 15-20 hours battery life with pretty heavy mp3 use, lots of texting, and about two hours or so actually on the phone. but i make sure i leave data/wifi/gps etc. off unless i need it. also, its a good idea to check and stop apps that automatically load with the phone that you dont need. imho the only roms that seem to drain the battery quicker are the sense based ones, at least from my own experience.

I was thinking about starting a new thread about this, but you are explaining EXACTLY what I am going through. I wake up today (after leaving my phone charging at night) and turn on my phone, and first thing I see is an 80% battery (this is a normal occurance). After literally doing NOTHING on it all day (except for a 30 minute call) it turns off by itself at 20%.... after 8 hours. So while I got 2 hours better than you, keep in mind that I did virtually nothing. What is worse about it is i'm supposedly using the "best rom" for battery life (AOSP 2.2. + battery tweak).
I've wiped battery stats (after reading the correct way to do it) and checked the health of my batter (reads as "good") and i'm still clueless. I'm wondering if I should even waste my money on a battery and hope that's it? I've only had the phone exactly a year and about a week so I'de be disappointed to know the battery lasts this short. I remember being on another froyo ROM (with the battery tweak) using it more than I am now going to bed anywhere between 30 and 50% which is about where it's at at lunch time now! I can't believe that i'm actually ok with the performance of my hero, it's just the battery that's killing me now !
And I plan on staying away from the GB ROMS until they get the GPS issue resolved. Let's just say that I was in Colorado a couple of weeks ago and my phone failed when I need it to work.... flashed froyo almost immediately when I got back (that's another topic)

i believe you are correct, if you got it from the download section of rom manager, its the same one, ben using for a while now, no FCs no issues. smooth and pretty fast too

frustration with my crappy

I have it rooted with gingerbread 2.3.5 and i am not pleased.
my phone was slow. like making me mad slow. Its like my phone only wants to be fast a couple. I had launcher pro , go sms and go key board. But then i uninstalled all except launcher pro and removed all my widgets. and its a little faster but its still really sluggish. also my battery seems like it goes down pretty fast.
Should i download a new rom ? Im thinking of getting a new phone also. i was thinking about an iphone but not sure .
Wich 2.3.5 and kernel?
I have Jvs
Well I can't offer any help on a I9000 rom. Haven't been on one of them for a while. I would recommend you trying a native rom. But Have you tried reflashing that same rom you are on?
is it stock or the custom rom? I am running S_Bamboo rom based on JVT and talon kernel...its really really smooth, fast and decent battery....
Im on apex , and i have tried reflashing . Im going to try a different kernel
My captivate was running extremely slowly (almost unusable) when I was running Mosaic VII. It was so bad that I almost dished out ~$600 for a new phone (contract wasn't up yet). As a last effort, I decided to try out CyanogenMod 7. To my amazement, my captivate is suddenly extraordinarily fast and ridiculously usable! The data connection is actually fast (used to take about 7 minutes to update Pulse (news reader), and now it completes in under 4 seconds), GPS is still meh but better than previously, and the phone interface is very snappy.
If you haven't tried it yet, I would highly recommend CyanogenMod to see if that solves your issues. It saved me a buttload of money since now I don't need a new phone until my contract is up!

how is your battery life though? I personally have had the best luck with pinnacle.
CM and miui had awful battery, and i would often have to turn off and on the data (at least once a day).
this also was when i was using nightlies (maybe a month before the stable release came out) is there any difference in the rom now? Should i give it a shot again?

CM7 has been great for speed and battery life for me. Absolutely astonishing. I don't even care about the SGSII anymore.
PS If you try it, I suggest doing a complete restore, i.e. not using Titanium Backup as it seemed to slow things down for me.

Going to give it a shot when I get home.
I'm optimistic, but I really can't see how it can even come close to a kh3 ROM.
If I just leave my phone in standby, after 10 hours, it might only go down to 85-90 percent. Last time I tried cm, it would go down 5% an hour.
The last nightly I remember flashing was around build 100 or so. Have they fixed the proprietary driver issue that causes the bad battery life?
Should I go with glitch kernal? Or stick with stock? And what glitch should I go with if I do use glitch?
Fingers crossed that it works better this time!

My battery life is actually extremely better than it was with Mosaic (and previous ROMs). After a day (from 8 AM to 11 PM) of pretty heavy use (reading emails, Pulse news, non-stop texting, and web surfing), my battery is probably between 10-20% left. Obviously thats not a lot (definitely requires a charge every night), but compared to my 8 AM - 5 PM (completely dead) battery life previously, it is a substantial increase. I have found that it drops from 100% to 60% pretty damn quickly, but then hovers in the 50-60% range for a long time (playing a 3D game for 30 minutes made it drop from 90% to 75%, but on a different day, the same 3D game for 30 minutes went from 66% to 65%).
I would definitely give it a shot again. I wouldn't do a backup and restore of your apps though....I'd reinstall each one again manually (you can restore the data to some apps if you want). Also, clear all caches and battery stats. Don't freak out if your battery dies to ~60% after an hour...it will stay around that percent for almost the entire day.
PS: On standby, this thing is a beast. From 8 PM to 11 AM (on standby completely while i was sleeping), it only lost 1% battery life. I don't use anything like Juice Defender or anything. Data was still enabled.
I've been using Serenity rc4.1, and about to flash rc5. Been fast, stable, and good battery life for me. Light use yielded me 1 day and about 17 hours on a charge. Haven't had any problems with wifi, gps, or really anything else. Good luck.

I use the stock kernel without any issues, but I've never tried any others. Modems are very geography dependent so it will take some trial and error. I am currently using UGKG3 with great success if you're looking for a starting point, and I've also had great luck with JJJV5, but YMMV.
Well, I'm writing from SGS2 right now, but I do have SGS too (my working phone no.), and I was not satisfied with with any stock (or/and) deoxed ROM I've tried (JVH,JVK,JVP,JVB, JVO,JVQ.....), because even fresh flashed or (and) tuned ROM felt sluggish to me. I've tried even few CM7nightlies, but I've been pushed away by some of it's aspects (it was fast, rock stable, but something around nightly #80, it wasn't mature yet for daily use). After a while on JVQ, I've finally decided to give that crappy chineese piece of **** a go...
Well, now I'm satisfied. MIUI ROM is based on CM7, so it's stable and fast, it can be configured to the bone, and with some gentle touch from MIUI team to the graphic design, it is best compromise between graphically advanced, but slow and unstable Samsung ROM and it's derivates, and superior rock stable and reliable CM7 which lacks any unified user friendly interface for all apps, and some details may not even work at all.

I've been running cyanogen 7 for a bit now and although the battery life isn't stellar it's definitely tolerable.
I would suggest using a design gears Tom or serendipity though. They are the closest to a stock cappuccino experience you're going to find.

So my phone was all the way down to 15% and I had practice, so it was idle for 2 hours and when i looked at it it said it had 25% left. and then it was idle for another 20 min and it said it was 27%.

[Q] Are the battery drain issues with ICS fixed yet?

Hey there,
In case you can't tell, I'm a newbie.
Anyways, I'm currently using a 6-yo HTC Dopod Pro and I've finally decided to get a new phone.
I really want to get a Galaxy Note but I hear that the Note has a relatively short battery life.
I also heard that ICS for the Note causes the battery to drain even quicker.
Have these issues been fixed yet?
Cheers.
What you have heard is misinformation. A bad installation of ICS, rogue apps and weird settings are the cause of people having battery issues with ICS.
The Note has one of the best battery lifes among all android phones.
Note has excellent battery life. I have the LQ2 ICS, and I have no weird battery drain, wakelocks or any other probs

I heard the battery life was pretty good whilst on GB but as soon as people upgrade to ICS, the life was substantially lower.
The battery drain "problem" of the GNote is like troubles with your Windows computer (IMHO): The more you fumble, worse it gets. Use it as it was designed and you'll be a happy person.
I have a GNote for a few months, it was Full Stock under GB and now is Full Stock under ICS. I use it moderately (2nd phone) and could easily manage 36 hours.
I pick it of the charger ~5h30, 6h00 in the morning and find it at 60~70% when I get home about 12 hours later (30~45 minutes talk time, not much else). I than read my favorite blogs and news papers that runs it down to 30-40% (reading takes about 1,5 hours).
When I go to bed it's never lower than 27-30%
The only problem I have is that it sometimes doesn't go in Deep Sleep and that I solve through a systematical reboot in the morning (of the charger).
As always (even people) the GNote is as good as you treat it
Hey Little Vince
Welcome to XDA!
I have had Note for over 6 months (bought from UK to Brissy) Been on ICS only last eight days or so - and I can report that the battery life is slightly better than GB. Speed is better too - not as much lag.
I have used Blackberry/Axim/Palm before and always got into the habit of charging overnight so anything longer than 24 hours doesnt really matter.
Please don't let others put you off a wonderful phone. It is so versatile.
PS - it always takes a few battery cycles (e.g. three or four days) before you get accurate info. I have had quick battery drain for a few hours after updating Kernel but it always settles down.

What is that systematical reboot you're talking about? Can you explain a little bit?
There are a few tricks suggested in this thread http://forum.xda-developers.com/showthread.php?t=1649041
I found my battery life was quite poor at first but it has improved after a few charging cycles. Also, I had a lot of syncing processes running (some duplicating others). Killing some of those also helped.

Never had an issue with batt drain, either on gb or ics... I think the latter is a bit better. I leave gps, wifi and 3g on all the time, and am a relatively heavy user... really haven't tweaked anything for batt life, other than removing some bloat.
OP, it would probably help if you told us what you would consider to be decent battery life. That way, people will be able to tell you if it is possible.
As for me, I'm on CM9 and have never tried stock ICS. I can confirm that battery life was better on GB, but CM9 still gets me through the day on fairly frequent use.
Usually fully charged when I get up in the morning (6am), and down to about 20-30% when I charge it at night before bed. This will normally include roughly 3-4 hours screen time from watching movies on the train and internet browsing throughout the day.
Same here no battery problem. I'm using DXLP9 firmware.

Nah battery drain is a real issue with ICS. It's too documented to be denied. Doesn't matter what I think is good battery life, but relatively with GB, it was 20-30% for about 12 hours of use (wife doesn't use it much) and after ICS, it's -110%. Hmm.. I meant for the 12 hours, it needs a charge and then some. And that's crazy since my wife really doesn't use it much.
Anyhow, this completely fixed it for me. Looks like there's a few bugs that you can come across if you have battery drain with ICS. Check the full thread for more details...

UPDATE: ok no. Still no real solution for fixing this after trying many over lots of days. AFAIK, kernal problem that Samsung needs to fix. And please do fix!!
As I see it from the times from BBS the problem of the drain is at standby mode where the battery for the start of locking and outing on sleep it eats slot of battery till it reaches the 1% every 1 hour and 45 minutes like it was on lc1 stock, even I had on GB 2 hours 45min for 1%, it starts with 1% for 30 minutes then 45 min 1 hour and so on till it reaches the max of it.
The use with screen on is the same 25% for 1 hour and 20-30 min screen on time with low brightness, as it was with GB. On GB I had 5h30m screen on with 10-14% battery left.
So the issue for me at least, is the standby aka sleep mode.

to the OP, yes battery drain is a documented issue on ICS, with the wake locks and rogue apps (for the unlucky few.. myself included)
i was on rooted stock GB and i used to have a good 72hrs of standby time for the note especially on the weekend when it is rarely used and maybe a good 48hrs on a weekday with average usage (about an hour's call, moderate surfing, facebook etc)
during days when i travel a lot i can be surfing and listening to music and doing calls for the better part of the day and the note still lasts a day with about 20% juice left by 7-8pm
however after I upgraded to ICS LP9, my battery couldn't even last me for a day without getting a few hours of charge from my laptop, i was on stock ICS for 2 weeks and did a lot of fine tuning just to optimize the battery life and ensure the phone goes into deep sleep and still not sufficient. the thing that blew it for me was when i noticed that my note started running at 1000mhz only and not any lower (even when charging - take note i was on unrooted ICS).. so decided that ICS with all its hype wasn't polished enough yet and was not worth it for me and went back to my stock rooted GB LC2
now i'm a happy camper.. note sleeps like a baby when it is supposed to and runs smoothly when called upon
so to answer your question (sorry about the long story) yes you can enjoy great battery life on note be it GB or ICS but you won't know until you get one for yourself.. and like what the other posters said the note is such a beast of a phone that you will not look into another phone again once you get one be it on GB or ICS
I absolutely would not recommend the G Note until there is another ICS update issued - unless you want to stick to GB (in which case I would definitely recommend).
Apart from the deep sleep problem, which for me anyway, cannot be resolved, I've had stability issues, overheating and it even pulls restarts without warning.
The only battery fixes that have kind of worked for me (and they still don't get me anywhere near the battery life I was getting with GB) involved me following a 5 step programme every time I charge my phone, which is frankly unacceptable.
FYI - I've had the note since December and it's running stock everything.
The Note is an amazing phone, but ICS has rendered mine not fit for purpose.
The sad thing is samsungs and android capabilities in finding the culprits. Fancy native battery charts which dont help much, if any in analyzing.
Only best case is to check deep sleep(cpuspy) , and if deep sleep is low check partial wakelocks in betterbatterystats.
Then you can find a lot of the culprits
Good thing the XDA community picks up where Samsung/google drop the ball.

To the OP. My Note on gingerbread had wonderful battery life 16+ hrs. After the ICS LPY update my note dies after 5 hours. To all the naysayers saying there are no issues with battery life on ICS, give me a break. Just google how many note and galaxy SII users on ICS are having battery drain issues.
I get exactly the same battery life on ics that I did on gb, the battery drain people are having has nothing to do with ics. It will be apps causing the issues. Im running exactly the same apps as I was before and its exactly the same battery.

mmm.... No.... The same apps, even after a factory reset and reinstalling apps I STILL had the drain. You say it's apps that aren't optimized? That could be true... but then again, I guess it must be a VERY VERY common app that's causing this because most everyone says they've experienced a decrease in battery life.

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.

The best ROM for a battery-HALF ILLUSION and placed on the scale smartas governor.
Try and tell me your impressions.
