Could anyone help me. I'm finding my bettery life is very short, I fully charged my phone and went straight to the market to update some apps via 3g and within 2 minutes my battery was down to 96%. I turned the phone off after that to go to bed and turned it on when I got up and it was on 91%. I am very new to flashing ROMs and flashed darky's 9.5 about 2 weeks ago. Il list my baseband and kernel below. I don't think out should run down that fast.
Firmware: 2.2.1
Baseband: I9000XXJVE
Kernel: 2.6.32.9 hardcorespeedmod k13d 500hz
Build: Darky's v9.5XWJS8
Thanks

Ok thanks, how long would you say it will take to be fully stable?

I find my battery drains badly when on Wi-FI. Now im on Ficeto JVH gingerbread. Very good standby time with wifi and 3g switched off.
I'm on JVH since a few days, and the Battery life is awesome! Before my battery was dead after max. 14h, more often after about 12h.
Now my phone is already running 29hours and still have 39% battery
phone usage as usual, when at home connected to wifi, else manually set to 2g, if needed switching to 3g. k9-Mail set to Imap-Idle, syncing only google-calendar/ contacts and facebook/twitter widget from LauncherPro Plus (every hour or if needed manually)
Il keep using it as normal for the next couple of days and see if it improves.
If it doesn't, how do I change my modem to a JVH?

Here`s some SS of my Jvh battery experience.
Right now, only used the phone to send 3 sms, 26h have passed and 93% of battery left.
Can I get a JVH modem without changing anything else then?

What rom/kernel do you have?
What programs for battery usage reduction?
What setup in general
Stock JVH Rom, stock kernel, no useless programs for battery reduction, everything stock, except for crt screen off animation, battery mod and root. HSDPA was on for about 2h while I played drag racing online.
My record was 7d and a few hours , with 2.2.1, using the phone only to talk. My average battery life is 3 days.
I don't know what happened but I'm having issues. I cannot get the display to fall below 75% and it sucks because between my EVO stock battery and my extended battery you can actually see the battery life being sucked away rapidly.

I have the same issue, it is isolated to Sense roms. It doesn't happen with AOSP, which is why those are the only roms I can use due to the battery life. We had a thread going for a while with some other people who had the same problem, but nobody could really get to the bottom of it. I reached out to Aamikam but he couldn't really help or didn't want to. I didn't know if a logcat or anything would have helped but no one really answered me. It happens on froyo and gingerbread sense roms, and I never had the issue for a long time but then I noticed it the first time on MikFroyo 4.62. I've tried everything since then but no results.
Only thing to do right now is switch to an AOSP rom, I highly recommend Team Nocturnal's Xplod. Very smooth with Tiamat 3.3.7 kernel and more eye candy than CM7. I would love to be able to use MikG again but my battery literally dies in 4 hours, regardless if I'm using the phone or not.
Alot of ppl seem to think that 75 percent or more of display is bad. Really it isn't. The battery stats need to equal 100 percent. On sense roms that's the way it is and there is nothing wrong with it. Now if your experiencing high.android system usage, that's a problem. As long as everything else is relatively low, its all good
Sent from my PC36100 using XDA App
Its after I installed the new update. Even downgraded to earlier gingerbread and still 75 plus.
Yes my system is low but I can watch my battery meter lower in realtime. Well I guess its time for a new toy.

If your actively using your phone and it drains rapidly that's pretty normal in my experience. But if its draining a lot during idle, check for a rogue running app. Otherwise not using auto brightness is a good mentioned trick along with underclocking with a new kernel should help
Sent from my PC36100 using XDA App
It has to do with the use of a generic power_profile.xml. Neither CM or stock use correct values for this.

You don't get it...this is not normal display usage. I remember what my battery usage and battery life was like before this problem came up and there was a huge difference. Before, cell standby was my highest usage and I could get 25-30 hours on a charge. Then display usage shot up to 90% give or take some, and battery life dropped to 4-8 hours. I can understand if display was slightly higher than everything else, but display is at 75-95% while everything else is under 5 or 10. There is absolutely no reason why the display usage should be that high even when the screen has been OFF the entire time. That's not normal. I have multiple screen shots to back it up.

So using bootmanager (finally works now) I loaded miui. And my display is no higher than 1%. So something is very very wrong with sense and 4.5 updates.

So, like many other folks here, I'm also trying to find ways to improve my battery life. Overnight, even if phone is fully charged, with 0 usage, the battery drains rapidly, to 20% by early morning. Android System seems to be the one using the most battery (51%). CPU Spy shows only 15% Deep Sleep time. Since I get emails at night, the softkey lights stay lit all night. I'm thinking that's what keeps the phone from going into deep sleep.
Question is - how do I turn off BLN? I understand many people here love the nitification lights, but I honestly don't care much for this feature.
Here's my setup:
Android Version: ICS Passion 10.6
Baseband: T959UVKB5
Kernel: 3.0.15-ICUP ICS-Streamline #1
Build #IML74K
Juice Defender Ultimate
Wifi connectivity at home and work.
settings-display- uncheck pulse notification light...and yes this will prevent your phone from going into deep sleep!
Perfect
Thank you!!!

It uses power, and when the phone goes into deep sleep the pulse uses enough energy to wake the CPU doesn't it?
Sent from my SGH-T959 using XDA App
Bet it is the email that is preventing the deep sleep and the BLN is a cursory problem bc of that.
now could i do that with my setup? talon kernel on honeycream jw1 2.3.6. i hate the backlight and with it off i could probably get around 3-4 more hours of battery life
Pretty sure backlighting isn't the culprit since it is probably to lightest battery drainer there is. It is what I'd causing the BLN to light up that is draining the battery.
well yes but no. For example psx4droid. If you press on the screen the soft keys light up for no reason and stay lit which uses more battery... that's the only reason I want them disabled,that and I don't need to know when I get texts as I check at least every 20 minutes and each texts means a pulse.... not good.

BLN I don't think has ever had problems with not deep sleeping. I remember Eugene tested his kernel with and without BLN because he wanted to test battery life, hardly any change was noticeable. It's most likely an app that isn't letting the phone sleep.

Even the original creator of BLN has tested the code, and AT MOST it uses a total of 2% of your total battery with the lights on constantly. These are very low energy leds we're talking about here that use a minuscule amount of energy, not 4 hours worth of battery.
It's an app that keeps your phone from deep idle, not the bln.
If you realty want to test, set your phone on airplane mode over night and heck your deep sleep times, and even try it with bln on and then check in the btery to se if your phone reports sleeping (only in gb and above).

Alright thanks buddy I checked today at school and battery life is only affected by a small ammount when leds are on all day

I upgraded the battery to the Galaxy S2 version of 1850mah. I get around 75% after a night's sleep.
Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.
4 hours later I'm down to 4% from a full charge.

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium
That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App
Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.
So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.
Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

I just updated to ics via ota and rooted my note. No custom Roms loaded.
I would like to tweak my phone for better battery life. Installed setcpu.
Anyone can share what's your stable setting?
Thanks in advance
Sent from my GT-N7000 using xda premium
Not sure what setcpu will give you for better battery life. Your not running an custom kernel to allow UV. The only thing you can do is set a screen of profile(I don't suggest this) or under clock it.
What's the normal cpu level?

Base on overnight status, I am running on 88% on 200mhz. Phone not sleeping at all.
Guys, or can u suggested a stable custom rom ? The reason why i am not on custom rom is because i am not sure which os more stable. I didn't want to end up flashing my phone every other day. I just wanted better battery life, and probably some mod to quicken the charging process. I use my phone mainly for whatsapp, email, foruming. Not really into games.
