Fixing battery problems with Rocket ROM

I've read in the Rocket ROM thread in the development forum that lots of people are having battery problems. And now me too.
Let's put our heads together and fix these "not ROM problems"
As I sit here, my phone has dropped from 100% charge to 90% in 35 minutes with maybe 10 minutes web use with 3G data on, GPS off, Bluetooth off and Wi-Fi off.
The phone is 33°c when air temp is 15°c.
I'm using Rocket v11, Abyss 2.3, setCPU with conservative governor.
So... Where to start?
Check list:
1. What speeds is your Note using? Use CPUspy to check if its range is limited and not using deep sleep mode.
Fix: ???

Get "CPU Spy" and check if phone is entering deep sleep or is stuck at a specific frequency.

Nicely spotted
No deep sleep. Seems stuck on 200mhz mostly. Now 82% battery in one hour of medium XDA browsing.
How do i unstick the 200mhz floor? SetCPU has 100 as the bottom and 1704 as max. But only 200 and 1400 are currently used.

Dont have a count or anything but seems to me that many of the people complaining about battery are on custom roms. Im not and my battery life is good.
Just a thought.

In the Rocket ROM forum several of the top people insist that just because it doesnt happen to them that it cant be the ROM.
On Nexus One the ROMs really blew away previous settings like a ghost image on windows. Here the ROMs seem more subtle and wont change some little setting we have wrong. So i agree. But lets find out how to fix the problem. Maybe an 8 point check list of problems and fixes can be created. I'll stick the fixes at bottom of my original post.

Almost all reviews and users are delighted with the battery performance on the note dute to the extra large battery fitted. So there is no battery usage problem to fix. I think you are misguided unless you can provide screenshots showing the bad performance using the latest stock ROM.

to make screen shot at any photo or app you just push the button in the note styles and just long press at any point in the screen.
good luck

I didn't know how to post this earlier. I've been messing around with flashing, installing and uninstalling all day. Here is what i grabbed earlier but it might be stale now.
Tonight I'll flatten the battery completely with the led torch and recharge it over night while switched off. I think battery has improved a bit after switching to Abyss 2.5
But I still don't know how to enable deep sleep mode. Anyone know?

Seems to be a some conflict between kernel and the OS if it's only using 200 and 1400 frequencies.
Try flashing FM kernel with CWM and retest.
When testing your phone must be UNPLUGED. The phone never goes into deepsleep when pluged in.
Edit:
Im running rocket v11 with the latest FM kernel and all is well. 1-3% battery drop per 6 hours idle.

Do you keep your wifi on constantly? That's what drains my battery every other day.

setup your wifi to go to sleep when not in use, unlock and root it, install a custom rom of your choice and flash a good kernel so you can do more tweaking and downclock/undervolt it.

I've actually found the battery life outstanding with standard ROM. My stats as of about an hour ago is 3 days with WiFi on constantly and running audible app the whole time, battery was down to 58%. When I compare this to my hox which needs twice daily charge just on idle.
Leave the machine on standby for a couple of days and see if there is a problem with the battery.
Sent from my Nexus 7 using Tapatalk 2

I'm currently at 2 days on this charge and still at 60% with 4 hours screen on time. Usually I get about a day and a half per charge by turning off WiFi when I'm not connected and having it turn off WiFi in sleep mode. I also don't keep auto brightness on, I adjust it myself. I find with auto my battery dies faster.

Thanks for your suggestions guys. I don't feel like crackfkashing yet lol. I already flash the hell out of my nexus s. Will try tomorrow and see how it turns out. Today I got 5 and half hours of screen time. Played a bunch of games though.

Agreed; i'm on aokp build 1 with no apparent bugs & awesome battery life. Seems much smoother than stock imo. I also had a couple of random reboots on stock, however have had none on build 1. All its missing is a bunch of rom control options that will no doubt come with future builds.

If I have my brightness turned way down I lose about 8% an hour when I'm browsing the internet. If I turn the brightness up to about 40 or 50% it will drop more like 15% an hour.

Absurd Battery Life

As much as I love my N7, the battery is absolutely terrible. I charge it up every night and by 9pm its dead with no usage at all. If I use it I can only get 2.5 hours on screen time. I've tried using it without apps, I've reset it, calibrated the battery, everything. I have no idea what to do. Thanks

Hmm looks blurry if looking from mobile app. Works fine on computer browser. Anyways, the screenshot shows battery at like 4 days and 5 hrs. 5 and half hours of screen on time with 7 percent battery left(which will last a good bit still). So either something is wrong with your n7 or maybe custom roms and kernals make that much of a difference.

It may be an app keeping it awake to sync or something. If it's a repeated issue I always look at what was installed that is similar or any changes I've made that are common between both devices

Look at the battery info screens. (Settings > Battery) That should give you some idea what's using so much battery. For most of us, the screen seems to be the main thing. For you, you'll probably see something else.

Aokp v4 android os bug?

I've ran a few other ROMs in the past, kaos droid being the last. I switched to aokp because of the android os was always so high and drained my battery very quickly, even when not in use.
Now I've come across the same problem with aokp v4. It didn't do this for about the month I've been running it, but the past few days it has kicked in.
Here's my graph:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Maybe changing the kernel will do the trick? I would go to the trinity kernel. I'm running with a faux kernel now, can't remember what it was with kaos droid.
Or is there another rom out there without this annoying bug?

Looking at that and JuiceDefender.
But Juice Defender hasn't been updated since January 2012... almost a year and a half. Not sure if it has full 4.0 support let alone 4.1 or 4.2... Snapdragon BatteryGuru seems updated regularly, last was May 30th this year just a little over a week ago.

unplugged around midnight last night, left alone for 11 hours then used. 11% loss in that 11 hours with only tibu running my nightly backup regiment.
