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.

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.

How hot is too hot?

Simple question, when playing a high end 3d game the back of my device feels very warm, the temp is only around 100 Fahrenheit. How hot is too hot?
Sent from my Nexus 7 using Tapatalk 2

I had to get a new nexus 7 because my previous one overheated to 120 Fahrenheit. I'd say 110 is the max.
Sent from my Nexus 7 using XDA Premium HD app

100-120F is still cold! the average body temp is 98.6F.
the safety shut off for the n7 is 100C, thermal throttle kicks in at 85C. 120F is just under 49C, well within the safety zone. i regularly see temps from 50-65C while gaming, maybe even a little more. that is normal, especially for games that heavily use the cpu. and remember, battery temperature is not the same as cpu temperature.

Thank you, my temp reading IS from the battery, how can i get the trinity app temperature widget to work?

tkt comes with a bunch of widgets..

High temps such as 120 is typical. Especially for a quad core. More cores... more heat.Especially since there is no fan or any type of air relief. I wouldn't worry too much.

try removing the no bg cpu temp widget, clear the app data for tkt, open tkt and set it up like you like, put the no bg cpu widget onto your homescreen, then start using your device and see if the temp appears..

I removed the widget from my home screen, cleared data and cache for tkt, then set everything up in tk i liked, then tried the cpu temp widget again
Unfortunately that did not work. Maybe i need to remove tkt and reinstall?

it also depends on the outside temp around you and your cpu speed. also how intensive youre cpu use is. sometimes my cpu wont go over 40C, if im not taxing the cpu very hard.

What games are you playing that it gets so hot? I can barely get it to 32-33° C.

nova 3 warms it up pretty well. when i actually finish the nearly 2gb download of horn( https://play.google.com/store/apps/details?id=com.Phosphor.Horn.Paid ), we'll see if it warms up the device

Tkt crashes when i try to use the cpu temp widgets.. i can get the widget up after it crashes, but it does not display a temp. Sent the report to tkt. I have reinstalled as well as cleared data and cache

what version tkt and what rom/kernel are you using? are you using superuser or supersu? is your busybox updated?

as far as temps i would say try to keep the cpu under 80c because if its anything like the i7 processor in computers, it will bug out past 95c. as far as battery i would just say keep it at a temp that won't burn your hand haha. i was in vegas in july when they were having those near record days of like 114+ give or take and my processor hit 160F (71c) and battery was at a solid 145F (63). granted these temps were on my evo lte but it should be similar to the nexus in terms of temps. needless to say i thought my had would melt but the phone was fine. so take from that what you wish

Best Battery/Governor Paramters?

First I'd like to start by saying sorry to the mods if this is 'spam'. If it is feel free to close it
Back on topic..... What are the theoreticaly best battery saving governors? And what are the parameters you are using?
--------------------
I'm on ondemmand
Settings:
Down differential: 3
Ignore nice load: off
Io is busy: off
Power save bias: 0
Sampling down factor: 1 step
Sampling rate: 20000
Up threshold: 95%
--------------------
On my Nexus S these settings would breathe 5-7 hour screen times in 24+ hours. On my N4 they suck. Interactive does better than this.
So what do you use and recommend?

Conservative, at 384 Mhz minimum would be the best for battery saving.
My point is: this is highly HIGHLY dependent on usage and how much performance the user is willing to sacrifice. I don't see how this information would be helpful to anyone.

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.
