For the third day in a row, my power draw stays nice and low around 30-60ma when idle with screen off and 200-300 with use. I can run all apps I want no change when I exit them and it reverts to 30-60ma.
As soon as I start the Amazon appstore the power shoots to the 400s and even after I exit it the power draw never drops below 250, even with the screen off.
Only way to "fix" is to reboot the phone.
If the appstore leaving some background process running all the time?

How long does it take the n1 to hit standby time after locking the screen? On set CPU I got standby's min and Max at the lowest settings. I think after I get somekind of notification the phone comes out of standby even the the screen stays on.
I have seen pretty many ROMs here, but am unable to make out which ROM is best optimized keeping battery life in mind. Could anyone please help suggest me a ROM or two that give the most of the battery life. Please.
You could take any ROM that will work with a kernel supporting OC/UV (like Setiron's) and use Xan's voltage app to limit the top speed of the CPU to something less than stock (1ghz is stock, your choices would be 800, 400, 200, 100)
Then apply an undervolt as low as you can go while still being stable.
This will of course result in a slower device, but that's the tradeoff. Less speed for more battery life.
Do note that the screen is the largest user of power by far and thus you can make the most difference by keeping the backlight as low as tolerable and shut it off whenever you aren't actively using it.

Thanks Da_G. I did use SetCPU, and set the speed to 800, but for some reason it is giving me lower battery life compared to without SetCPU. So took it out.
Also, I have my screen brightness turned all the way down with auto set to off.
I meant to ask for a ROM that has all the battery hogging stuff in it removed/optimized.
I am currently like 45% left after about 8 hours with moderate usage. Trying to see if I can stretch more than this.
My today's usage statistics:
1. 11 hours 25 min 4 secs since unplugged
2. Battery remaining: 63%
3. Voice calls: 1h 10m 15s
4. Display: 1h 15m 42s
5. 2 gmail accounts with push turned on with about 10 mails delivered today
6. google voice with push all time with about 100-120 messages delivered using push
a. I do not have SetCPU.
b. I have my brightness set to 0, with auto-brightness turned off.
c. I used SamServMode to turn on EDGE, and 3G turned off since the phone was off charging hook. In short, on EDGE all the time.
d. Static but nice, colored wall paper.
Could anyone suggest me if this is good enough. And any ROM that could get me battery atleast on par with what I am getting.
A few of my ideas:
1. Use a dark colored theme. Our nice SUPER AMOLED screens don't use up much power to draw black - so the more black - the merrier.
2. Be careful of what extra apps running. Things like widget locker are one more app to run. Go slender. Theme's are okay if they replace files like frameworkres.apk but if they run in background (see it under processes) then that's bad.
3. Be extra careful of making sure you are fully charged when you flash. This means, charge, turn off, charge, turn on, charge, flash. I get a little more charge when I go back to eclair stock .
also note that 95% of battery is the screen
Everything else that was said before me was spot on so try that too.

Thank you kind sir. I shall do this. But I am not flashing anymore.
I loaded the AOSP ROM from Spaceman here
Code:

and am getting pretty much the battery backup I was getting with stock.
Thanks a bunch everyone who helped me on this.
So I was about to do a benchmark with system monitor open and when antutu started, only 2 cores would turn on. I exited out, and began going through settings, power save was off, I have no cpu apps and I'm not rooted. I decided to reboot and opened system monitor and all four cores were on and active. Any idea what might have happened?

Perhaps it entered into some power saving mode that we don't know about? (Other than the one in the quick toggles)
What was the battery percentage at?
75%. Temperature was normal and two cores were allowed to go to 2.3 so I don't think it's throttling. I have developer options enabled, but nothing changed (it was just to check out the options)
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
What is the difference between the mid and max mode? If you look at their options shown, it appears the only difference is the resolution of the screen. However, no way that adds like 5 hours of time to your phone by switching that. To verify that's not the only difference, I tried customizing the mid power save mode and dropped the resolution down to HD+ just like the max power save mode. You know how much time that added? 3 minutes. So where are the extra HOURS of time coming from on the max power save mode? It has to be doing more than it shows...
it's "Maximum power saving mode".
CPU speed will be limited, almost applications will be sleep. Then, you will get a really phone.
