As I am running a stock xt905 rom with xt902 radio on my xt902 and I have many times flashed a new rom and many times reset the fone via recovery
Betterbattery stats show kernal wakelock of suspend_backoff
I searched it and did the settings in chrome but still no help.
The processor keeps running at 384mhz as indicated by cpu spy even when the screen is off
And I have also tried stick Verizon xt907 rom and it still shows the same battery drain!

To my knowledge, the processor in these phones can only go as low as 384 MHz. With certain governors it will turn off one of the cores but that's about it. How much battery life do you get before a recharge?

Wow that's strange... I'm afraid I wouldn't know. Check your battery stats and see if the phone is awake while the screen is off. Also, try changing governors to something like msm-dvsc. That should put your phone into deep sleep properly.

2 hours of screen time there, that seems about normal to me. I'm lucky if I squeeze out 3 hours of screen time throughout the day.

It depends entirely on what you are doing. 2 hours of screen time (even in ideal conditions) will most likely get through half of your battery.
What screen brightness settings do you use?
What were you doing with the "screen on"? (i.e. gaming, video etc).
What kernel do you use? Try the Faux 1.0 Ghz kernel (if not already) and consider undervolting.
I imagine with the combo of Faux's stock kernel, undervolting and perhaps reducing screen brightness will see 5ish hours of screen time.
It was on around 85% brightness due to being under direct sunlight.
My kernel is faux's 1.45 for CM
Over 80% of the time the clock was around 200, 400MHZ as stated by SetCPU, and both those clocks are undervolted by 50.
I was browsing the whole time.

Wow no wonder. Roaming for 2 hours with brightness nearly on full will definitely drain your battery.v Plus the 1.45 Ghz kernel overclocks the RAM and GPU also. You might want to get an anti glare screen-protector and flash the 1.3 Ghz kernel and use wifi.

Umm... wifi wasn't an option back there, and I don't use screen protectors. BUT I didn't know that bit of fact from faux's kernel, I'll put in the 1.3
BTW, Green power pro does help a ****load on keeping battery alive.
ps: anyway to control RAM and GPU clocks the way we do with SetCPU with the... well... cpu?

I don't believe setcpu functions correctly for dual core devices, I remember reading, albeit a while ago, setcpu only effects 1 core, leaving the second untamed.
Please correct me if I'm wrong. Stock cm kernel has plenty of ass behind it, no ones playing bf3 on their handsets....yet...

Watchdog shows the suspend process and android media process taking up about 30% usage constantly. Signal is strong when I'm at work, constant 4-5 bars H+
Even after a full wipe and clean install of CM7 those same processes throw up alerts immediately, I will get al alert for the suspend process every few mins.
Background data off, no email syncing or anything. I'm lucky to get 3 hours screen on time or pandora streaming. I bought a new Motorola battery about a month ago and I don't use GPS or wifi.
Running stock, aura or homebase and the drain is gone... they aren't any good IMO tho.
For now I'm carrying a spare charger everywhere I go till the nexus prime is released.

ICS is still android lol
I know what you meant though. Just saying
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).

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.

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.

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.

Hi All,
Want to share with you, experimented the XXLT5 on GTN7000. Superb ROM....so far no issues....you name it, it works fine. Note the downloaded file is above 1GB...seems this has all the fixes required. You can root it as well....if any issues found on this stock rom do let me know....will be interested to catch the bug.
Link for download...http://www.hotfile.com/dl/213299077/83496c8/N7000XXLT5_N7000OXXLT2_XEH.zip.html
Link for root : http://d-h.st/GiO
Installation...as usual....Odin...so have a latest pack..open, select the PDA and good to go.
the hotspot works?

Something must be wrong with the phone if you have such a high CPU usage after a fresh install. Send it in for servicing.

first, whats your upgrade procedure, try without restoring stuff and let os settle in. restoring app+data usually causes this with me.
Also what app do you use for measuring cpu usage. That may be off for some reason. Also note cpu utilization v. s. governor. Example on demand scales up frequency when e. g. uses 80%, so it will seem high, but in regard to frequency it is not. Due to battery savings lower frequencies are used, until 80% frequency is reached before going to a higher frequency, thus for same task higher utilization of that frequency it may not be a bad indication is what I am saying.
Now a rom usually needs some time to synch, perform breakin tasks, scan all media etc, try to see through settings, development options then cpu utilization what is utilizing cpu. Maybe app has gone bad, rogue, or maybe its expected.
M using CPU Z, thanx for utilization info

Look if the serial number of your battery starts with BD and if it's swollen. If this is the case, go to a Samsung service and you will get a new one for free.
