Also inverted apps GREATLY help. I am not of fan of them... but I know for a fact black is a lot easier on my screen. If everything I had was black (app wise) opposed to white I could squeeze out at least an extra hour.

Slightly off topic, but how was your battery when you first flashed your ROMs? Was it good like it is now? I've probably asked this before but I've never got a straight answer. Does the OS calibrate itself or something? I don't think it would actually make a difference since that's more for the gauge than anything. It just seems like either I have a hardware issue or the stock batteries I have are just bad.
[Nexus S General] 309041291a:
I was use different settings so the battery was worse. Getting to the other part of your question, about calibration... Other times I've used these settings right away and got worse stats. Usually you have to run the stats from 100% - 0% (let your phone die and turn off), then fully charge it. In doing so (while sticking to ONE setting) I've always noticed better battery life the second time around... I believe that its good on the Lithium battery. So a combination of the OS and actually battery calibrating I would guess.

I had a good experience with lionheart actually. I had my phone lock up from something though. Weird because it happened twice around 115 hours of up time :/ . I'm gonna give it another go though :).
[Nexus S General] 309041291a:
Lionheart gives me great speed, comparable with ondemmand, if not better. And the battery life... I will update screens Friday latest, to prove of my 4 hours + on-screen. Idling is amazing. You may see it in the screens. I can put my phone down with 23% (for example) and come back 9 hours or so later with 23 (sometimes even 24-26)% battery life. Of course turn deep idle off and go at 1000 Max settings 100 min. And make sure you're using Noop. I've frozen a few apps (which didn't affect my battery at all...) and I used auto starts (which actually Doss help a lot!). I have 0 wake locks :P. Well tiny ones that last maybe a minute once er twice, but everyone has at least that. Lastly BLX is at 96.

4 hours and 7 minutes of on-screen use in close to 12 hours. You can see the awesome idling my phone has, the percent goes up :P. Android System at only 5%.

GummyNex 1.0.2, Matrix 19.0, 4.0.4 (Second day)

Top Battery Killers

Screen

Chart

4 hours and 25 minutes of on-screen use 9 hours and 20 minutes. The idling is a lot worse in these screens. This test was done at school versus the last at home, for some reason IDLING is generally worse at school... Android System was at a whopping 18%. Sent a lot more texts with this one too.

GummyNex 1.0.4, Matrix 19.5, 4.0.4 (Upgrade)

Top Batter Killers

Screen

Chart

First off, for some reason an hour of idling and 10 minutes of on-screen use just disappeared from my batter section... In the screen you can even see a small gap. The phone did not reboot at all. So I'm a little confused about that. Really it is 4 hours and 11 minutes of on-screen use, and 7 hours and 30 minutes of general use. Android System back down to 9%. I played Zenonia 4 for a while longer, which saved more battery than actual browsing the internet did :P. Listened to a lot of music like the first screen too, so the slightly higher Android System % I find reasonable. This build was done at on a weekend with nothing to do so I went straight for use, I tried to show off some idling in that hour margin that seems to have vanished...

I'm wondering if the Android System will spike in the battery consumption on a second day of trial like it did with the previous build... Overall the builds both see very similar results. The upgraded version feels a little more stable and fluid to me though. I can't seem to connect with USB storage on the upgrade for some reason so I had to restore with a NANDROID to upload my screens. Media Server and Android System seem to need some 'tuning' for lower and more consistent results.

All of the tests never had a proper battery cycle prior to, so I'm going to give my phone a few proper cycles soon. Maybe we'll see better results.

If you downgrade to gingerbread use release 2.37 you will see a big improvement to your battery life vs ics 4.04/4.03
[Nexus S General] 309041291a:
I'm going to loose the plenty of new features and gorgeous ICS UI if I do that though :P.

The 1.0.4 version of GummyNex all of a sudden is giving me a ton of errors. So I'm going to go back to 1.0.2 and use Matrix 19.5. That's what I recommend.
[Nexus S General] chronophase1:
Lol. Once you go ICS, you never go back. Your graph looks like a ski slope:p .
[Nexus S General] 309041291a:
Haha, I usually go right into using it. When I start I don't stop for a while :P. I could probably hit 5-6 hours of on-screen use with airplane mode on. But that defeats the purpose of having a phone in my opinion...
[Nexus S General] davidsteele1975:
I keep flitting between newer builds of ICS and Blandroid 2.3.7p0. I love ICS until some point in the afternoon or evening, when my battery is low. Gingerbread is snappier and has better battery life and most of the time I persuade myself that I don't miss the new features. :p

I got pretty good usage today. I'm running the latest rascream build on the euroskank site along with trinity t12 (mostly at 1ghz and then at 1.2ghz for the last few hours of usage). I think the most important thing is to find out what apps are running while the screen is off so that there's minimal drain with the screen off. With my current setup I uninstalled maps from /system/app and reinstalled maps from the market and then I used autostarts to limit what apps I let run in the background. I tried disabling maps in autostarts when it was installed as a /system/app and that caused some drainage issues so I fixed that by doing what I mentioned and seems to be working quite well so far. I have maps disabled in autostarts now that it is not in /system/apps btw.

Edit: I'm also using some inverted apps from here
[Nexus S General] :
Oem battery?
[Nexus S General] glennkaonang:
Which T-12 are you running? 50Hz or 56Hz?

Do you mess with the governor parameters or leave them as they are?

So, with Maps disbled in Autostarts, does it mean that you don't have location services running?

Anyway, I think rascarlo's ROM also helps a lot.

The colors are mostly black, which is a huge advantage for SAMOLED display.
[Nexus S General] tycruickshank:
Yeah this is just the stock battery.

I'm running the latest T12 which is 56hz. It's the one with voltage control that just got put in. I agree with the black helping and the inverted apps help as well. Governor parameters and all that are just left as is so on demand and deadline with the stock sampling rate and up threshold. Location services are turned on in settings if that's what you're referring to? So if the browser or some app needs my location it can still get it.
[Nexus S General] :
Oh...then it means it really is imposible to get past 4h with my 9023 since its slcd and no amoleds are here in romania
[Nexus S General] tycruickshank:
I honestly feel like you can if you have the brightness all the way down. I used to have an i9023 and I was able to get pretty decent screen on time. Also as a side note I've found that disabling maps in autostarts may not be the best idea because sometimes on my phone maps will keep trying to restart itself which causes a wakelock that doesn't go away.

Cyan Ultra 1.0.1 flashed over the CNA 2.0RC without wipe.. the best battery life I had on my Nexus S. That including about 2h of music streaming over the Bluetooth (which is always on) and about 30min of PlayStation game using Bluetooth controller. Pure black background and textures makes a difference.

To squeeze my i9023 to 5 hours screen time at on charge, takes a few tweaks.

Tasker handles most of it automatically. When connected to wifi, i use 2G only. Outside my house i'm on 3G and wifi off. Sync turned on for 5 min. every 30 min. Flightmode at night. GPS is normally turned off. Only auto backlight when i'm outside.

I've overclocked the phone to 100/1200 and use the smartass2 governor.

Little bit of whatsapp

Little bit of calling

Lots and lots and lots of text messaging with strong haptic feedback

25% brightness

I have always been extremely satisfied with my battery life compared to other android phones and I did this test to use my phone just as a phone and it really didnt disappoint me.
[Nexus S General] chronophase1:
You can find it on the screen before that graph. It'll say screen and a percentage next to it. Tap that and it'll tell you the total amount the screen has been on. Looks like you barely used the damn thing:p. Either way, that's impressive. I don't even think my phone would last 24 hours if I left the damn thing in standby:(
[Nexus S General] Gambler_3:
Ah thanks I see that now.

Well I think I did around 150 sms with strong haptic feedback which is pretty good I think. I slept 3 times in between so that obviously helped lol. :p

What are you doing with your phone? The stanby time is so good I lose around 2% over night. :)
[Nexus S General] smoka206:
Looking at some of these screens for battery life. It seems like most of them do not do much else other than using the screen. Take a look at mine at tell me if this is why I cannot achieve more than 3 hours of screen time. I used GPS for over an hour on 2g using endomondo and played music via power-amp using the media server for 1h 35m. I know I could squeeze more out of the screen if I didn't use the GPS it kills battery and heats up the phone more than anything and heat kills the batter too. I am currently using AOKP 37 and using Air-kernel 4.2 voodoo colors only. Live OC min 110 max 880 ondemand/noop. AOKP is very fast at the moment and i love it, I let it idle over night for 8 hours only lost 2%. I haven't tried gummy but I may try it if its that much better at battery life. Most of the time I use wi-fi and 2g when I'm away unless I need the more speed then I switch to 3g. What are other peoples opions on Gummy is it really that much better than the others for battery. How is performance? I would just flash it but I'm flashed out at the moment, and I like AOKP performance more than anything. Battery life is not a huge deal for me, I work in at a office where I can plug in my phone at anytime, I also have a portable charger for when I am outdoors.
[Nexus S General] chronophase1:
I've done nothing out of the ordinary. Its always been like this. Only thing syncing is Gmail, edge speeds all day. Wifi for heavy lifting when I get home. I stress it now and then because my G2 was absolutely phenomenal with battery and it bums me out. But I need to take into account I'm using this phone much much more. I've never had the phone just die on me during the day though , so its really not too bad. I have a car charger and a spare when I go out and won't be home for long periods of time.

Also, the thread is about screen usage. Lol. I average 3:20 every day no matter what, so at least it's consistent in that aspect.

Don't mean to get a little off topic, but constitutes as a charge cycle? From full to 0%? Or can you go from full and go to like 10% which would be 90% of a cycle? I hear I should run the battery through maybe one or 2 of these to not necessarily calibrate the battery, but the gauge and graph. It's weird because I could be at 75% and my battery voltage would still be 4v:confused: .

It's possible because you use Rascream on an AMOLED Nexus.

The black background instead of gradient really benefits AMOLED screen in terms of power saving.

It doesn't make any difference on SLCD, though.

I really dont think the i9020 will have better battery time with stock OS. The messaging app has the white background which will really tax the amoled screen. It's actually quite shocking that the messaging app has white background because the galaxy nexus has an AMOLED screen too with no LCD variant which should be google's main focus.

And the settings menu has the greyish background which again doesnt really give any edge to the AMOLED. It's just that when you get into tweaking things your way then surely you can get more time with the i9020.

I only recently discovered the option to see the on-screen time :P so I will report back with some proper usage for a few days to see how it is.
