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.
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?
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)
Hi all, I have been thinking lately about moving to WQHD resolution instead of the FHD that I'm already on. Can someone please share the battery impact and the actual screen sharpness? I have always maintained that the smaller the screen the more difficult it is to discern the actual difference between FHD and WQHD. Surely, the difference is day and night on larger screen sizes i.e. 50 inches and above. Is it really the case on our screens too? I'm on adaptive refresh rate and plan to keep it as is.

Not much of a difference in battery , may be like 30 mins of less SOT.
Gpu takes a bit of more load , and thus the overall graphics might be like 5-10% slow .
Thats my opinion, might be different for others
The difference is nearly imperceptible, wouldn't worry too much about both WQHD+ and adaptive refresh rate
Buying a phone at this price but not using the highest possible resolution is quite useless
why cant you just TRY IT YOURSELF?

You could NOT have used the CAPS and I would have still understood your point!

Hi.
I tried both WQHD+ and FHD+ with adaptive refresh rate on for a few days each - but I couldn't discern any significant differnce in battery life with day to day usage. I'm not saying there wasn't any... common sense dictates that there must be some, but I wansn't able to appreciate it.
I was very hard pressed to tell the differnce between the two resolutions on my screen as well. When I went down to HD+, I could immediately detect the drop in quality. But between FHD and WQHD I couldn't tell initially. Over time, i leatnt to discern the differnce up close (really close) becasue I knew what to look for - but the difference was not very big. So I tested it out on my family members, and not a single person could tell the difference with confidence (none are tech nerds) - all they said is "Wow! nice screen, what do you want me to look for? Looks the same as before..."
But this was all done in the first 2 weeks since I bought the phone, so usage was erratic and frenzied. I hadn't settled into a regular routine with the phone, it being all new and shiny - installing and uninstalling new apps, tinkering around etc - so i don't think I can honestly testify as to the battery life difference between FHD and WQHD.
But I can definitely tell that my eyes found it very difficult to tell the difference in quality, even today. So I just kept it on FHD+ and forgot about it till I came across your post. Maybe it's time to try out the experiment again with a more settled down phone... as I sit here typing this on WQHD resolution, trying to imagine if the FHD+ looked any different 15 minutes ago.

I tried it and didn't see much difference so keeping it at wqhd and adaptive.
Same with 4g and 5g in my area.
Everything is on adaptive. 5g and wqhd.
Go on and use it. That's why you paid for the phone, if you don't use the feature s what's the point?
Just use the best possible resolution. No point getting a phone like this and turn things off is how i look at it.
70% of the time, on my phone: I'm just messaging/calling or using the browser to view text-based content with a few images here and there.
30% of the time: HD Video, photos, camera, video-calls, etc.
So, I do this:
(1) Remove Animations (under Accessibility or just use Finder/search to locate it) -- because I don't need
(2) Force Dark in Developer Options (goes away after a reboot, so just reactivate this).
(3) Keep the phone in 720p60fps, full-temperature Comfort Shield, Power Saving mode, AOD off, Limit CPU to 70%, Decrease brightness by 10%, etc.
(4) Use a Bixby Routine to go into and come out of this low-quality mode as desired.
(5) I have all deviceidle and other power saving settings turned off.

Now your phone will always stay dark on reboot. You're welcome.
