Yah I hate to be that guy but where's the guide? Everyone uses their phone different. You should at least show your battery usage screen shot so we can see screen time etc.
[Samsung Galaxy Nexus] deaffob:
What? Are you telling me that you get 8hrs of screen on time? Is this trolling or just a language barrier?
[Samsung Galaxy Nexus] wissamidrissi:
sorry, I wiped stats but you can study this.

just look at my charge time compared to the times I am using phone, and because it last longer I don't care when its red and low, I was in 5% from 9pm to 11pm chatting from time to time and facebook, and btw my wifi is always on.

and pardon me I am new Xd I am just sharing something not an expert or something :P but next time I will make sure : it's called underclocking <- I though both are same, and post screenshot and screen on time :D

EDIT: I think I should charge it to 100% and make it drain then share pics with you guys, that's the proper way for screenshot right Xd? cuz mine looks like a mess XD

My guide for 18+ hours:

Stock. :)
[Samsung Galaxy Nexus] wissamidrissi:
Nice XD but I love messing around my phone :P stock is just... normal XD
[Samsung Galaxy Nexus] 95Z28:
Your phone was plugged in multiple times throughout your screenshots. So yes, you should redo screen shots from 100% and include display on time.

It doesn't really matter though, as no one will see your same results unless they use their phone the exact same way.

And under clocking is unnecessary on the nexus, it doesn't spend hardly any time at 1200mhz anyway. I use mine for a lot of game play and still don't spend much time over 691mhz (Trinity kernel). So if my phone decides it does need to ramp up to 1190mhz to remain buttery smooth I'm not going to interfere.
[Samsung Galaxy Nexus] superted125:
Nice. Will check this out.. I run my phone down pretty quick these days heh
[Samsung Galaxy Nexus] eqjunkie829:
I'm not understanding why you prefer 1.5 trinity kernel and 307 gpu. What benefit are you seeing versus the other trinity kernels with higher gpu and lower overclock limits? Are you running your phone at 1.5?
[Samsung Galaxy Nexus] UncleMike:
Same here. I have no problem getting 18 hours out of my stock battery using the stock ROM and kernel, including just shy of 6 hours of screen on time.
[Samsung Galaxy Nexus] muyoso:
I dont know that I would call this a guide. Its saying to use a certain rom and kernel and to charge the phone. . . . .
[Samsung Galaxy Nexus] jayochs:
hey thanks for the write up... i used it alone to change the colors! now my screen isn't yellow.

question though... when I adjust my colors manually, when I go to 0 percent brightness, everything goes like super green... like crazy looking lol.. but at 3 percent it's fine again... any idea why this happens and how I can fix it to get true 0 percent? thanks!
[Samsung Galaxy Nexus] alfablac:
I'm using a stock one and all I can say is: Just dont use Nexus as a videogame.

I got 3 days and some hours of battery talking some minutes and using wifi for some time (probably 4 hours overall).

Playing sucks up the battery life. At least for me.

A normal day of use, with wifi active, many calls, auto bright and SetCPU profiles gives me 'bout 18-24 hours of use.

A intense play day gives me 8 hours. And I think its generous.

:victory:
[Samsung Galaxy Nexus] wissamidrissi:
Finally I helped one person, thanks man I love you XD

and this guide is just experience, because most people are wondering what is best rom and kernel combination, well this was best for me at least.
[Samsung Galaxy Nexus] rayiskon:
full stock
[Samsung Galaxy Nexus] mrsbelpit:
^What brightness setting? I seem to only get about 3 hours.
[Samsung Galaxy Nexus] wissamidrissi:
Nice :D but I see u got less screen awake time because of temple run ^^ you can squeeze more but that would mean never play at all.
[Samsung Galaxy Nexus] rayiskon:
I use autobrightness.

I used to get between 5 and 5:30 screen ON on ics, i'm getting ~1h less on JB.
[Samsung Galaxy Nexus] I Am Marino:
Easy to get 18 hours if you don't use screen much.

I get 4 hours screen on time with 18 hours-ish standby as well.

No auto sync, brightness down, 4G rarely. GPS, Bluetooth, and Wifi off whenever not using it.

Black theme.
[Samsung Galaxy Nexus] rayiskon:
If u're using low brightness levels the black theme won't help u much, it drains *nearly* as much as a white screen ;)
[Samsung Galaxy Nexus] robs898:
Thumbs up for Trinity definitely the best kernel for battery life in my book However 8 hours screen on time seems crazy most ive seen is 5. I'm not sure how much extra battery you will get from underclocking too....
[Samsung Galaxy Nexus] wissamidrissi:
Because maybe I spend most of my time on chat or browser XD
[Samsung Galaxy Nexus] SpecRek9:
We should be able to use our JB GN the way we like it whithout worrying -much- on battery life, if a custom JB rom can improve battery life, then google for sure could and should send the same fix ota; it's annoying to have such a beautiful phone/os and just being able to use it 5 to 6 hours upon full charge, or, how would engineers at google feel if their cars needed a tire change every day after work?
[Samsung Galaxy Nexus] zAlbee:
18 hours is nothing special. I easily get 1 day+ of battery life, but I have trouble hitting more than 2.5 hours of screen on time. A few tweaks to Google Now, Facebook, and a reboot seemed to help so far though...
[Samsung Galaxy Nexus] varunoza:
Do we really need custom roms and kernals? ive been using stock rooted JB and easily get around 5-6 hrs screen on time with around 16 hrs usage. (tried with 100% battery and allowed it to drain down to 5%)
[Samsung Galaxy Nexus] lightsout:
It seems like screen on time varies how it drains the battery. I normally can get through the day using my phone casually throughout the day.

But this weekend I was out of town. Using my phone more than normal. And with the screen on constantly I could barely get 2 or so hours. With vicious and francos kernel.

For whatever reason it felt like constant use instead of sporadic really drained it faster. This was on 3 g with very low brightness
[Samsung Galaxy Nexus] shinydesert:
This is the most I can get in a day like today,with lots of use,browsing like crazy,emails,whatsapp,a couple of VOIP calls,some Temple Run,Gtalk and music player. I am also showing the apps that I disabled and the ones that are disable when the device starts or restarts.

[Samsung Galaxy Nexus] AshtonTS:
Same here. Its not even funny. I get ~2:30 screen on time

Sent from my HTC Droid Incredible
[Samsung Galaxy Nexus] 1heffer:
Yup, 2 maybe 2.5 hours screen on here too. I don't want to cripple the thing to get up to 4 hrs screen time so i guess im going to have to get a couple more batteries.
[Samsung Galaxy Nexus] msavic6:
I dont cripple my phone at all, I keep brightness manually set, gmail syncing, have the Facebook app installed and use 3G for most of the time and am able to get 18 hours standby with 3:30 screen on time.
[Samsung Galaxy Nexus] jayochs:
just like with the rezound, ill never understand how certain members get 4 hours screen on with 18 hours total. that's insane. I can't even break 3. either way I dunno how battery is on trinity because I used my phone so much for texting today that I had to change again around 45 percent with like 5 hours off lol so I can't tell of trinity is draining me more or what compared to stock.
[Samsung Galaxy Nexus] UncleMike:
The difference between my Bionic and GSM Nexus is like night and day. I believe a large part of that has to do with signal strength - at home my Bionic typically had a signal strength of around -98, while my Nexus gets around -81. I posted screen shots from my Nexus in another thread showing 18 hours total time since charging, during which I had 5 hours 51 minutes of screen on time.
[Samsung Galaxy Nexus] Blac Caesar:
If you guys are really looking for a fulproof way to extend your battery life, go on the Play Store and download the app.. Juice Defender Beta, followed by the paid version.. Juice Defender Ultimate. You have to do it that way, as JD Ultimate works like an unlock key. What Juice Defender does, is disable your data connection while you screen is off.. then enabling it when you unlock your phone.

I've found that this is really the only way to truly increase battery life, bc once you set the parameters in JD's settings.. it'll do it on the fly for you. Also, you can train Wifi locations so JD will enable Wifi when you're in range and then automatically disable it when you're out of range. I recently wiped my phone, so it's relearning my Wifi location.. I know I don't have a Nexus, but I've OC'd my HTC Vivid to 1.62Ghz and I still get about 10-17hrs w/Juice Defender's help. Let me know if this helps anyone!

[Samsung Galaxy Nexus] isinisterx:
I feel that the minute I only get 3 out of 4 bars reception while using 3g, my phone just skydives in battery usage. Anyone else find the same?

I'm on Wind .. so that may be the problem :S
[Samsung Galaxy Nexus] MersauX:
Well, two 2 days + are no problem on standy by, you can go for four or more, I think if you are not touching your phone. I'm currently on vacation and I'm roaming and have no wi-fi and I spend most of my time on the beach, so the phone isn't used really. Here is the current result.

As for the usual usage with a lot of scree on, I just got the phone last week and then went on vacation, so I didn't have time to test it. But I'm on stock JB 4.1.1, bootloader unlocked and rooted.
[Samsung Galaxy Nexus] zetsumeikuro:
Ah the battery life of a GSM Gnex.. I am jelly.
[Samsung Galaxy Nexus] rayiskon:
There is a thread about those tests somewhere around here, i would link u to it if i was at my pc. On high brightness levels there is a big difference in screen drain between white and black backgrounds, on low brightness the difference is very small, coz even on full black backgrounds pixels don't shut off completely.
[Samsung Galaxy Nexus] jackfrost3821:
Its funny because my phone hardly hits screen-on time of 2 hours. I'm on XenonHD ROM with trinity kernel. :rolleyes:
[Samsung Galaxy Nexus] kongkard:
I think depend on personal using :mad:
[Samsung Galaxy Nexus] wissamidrissi:
That up closes my wireless in most times when I need it and I keep missing emails, in other words it makes the phone un-usable, I would buy a nokia 3310 if I am gonna stay without those things ON. just my personal opinion that's why I am doing best trying different roms and kernels until I found this.
[Samsung Galaxy Nexus] Blac Caesar:
Uhh.. except for the fact that, IN THE SETTINGS AND PARAMETERS, you can tell JD Ultimate to keep your Wifi up n running, even when you're not using your phone. I've been using JD since I had my Atrix 4G two years ago.. and it's never let me down. Check your settings again n you'll see. See in my screenshot...

[Samsung Galaxy Nexus] wissamidrissi:
You have huge drop downs, your governor is not good it sucks lot of power, I think you should use [conservative] <- sorry if I got this wrong.

[Samsung Galaxy Nexus] samleung:
If memory serves me right, when I got my phone, it was 4.0.3 (maybe 4.0.2) out of the box. I immediately rooted it and put AOKP onto it. I flashed JB roms as soon as they were available. This basically means my radio has never been updated right? What radio should I use for East Asia? (GSM Galaxy Nexus here). Thanks!
[Samsung Galaxy Nexus] Evil0verlord:
I get 1d 1h or 1d 2h with 3hours screentime,

on Xenon HD v5 with imoseyon lean kernel 4.2.0 stable.

But then I am also using SetCPU to hotplug cores on screen off & low CPU loads.

Hearing good things about Trinity , will try & mix a combo with that.

Imo, after testing custom roms+kernels.

For ICS best battery combo is BAMF Paradigm + Franco

for JB its XenonHD+ (best battery kernel I'm still trying to lock on)

Haven't tried stock JB combo with kernels though. Will do that once I decide on a kernel. :cowboy:

I'm on stock jb with Franco kernel with the CPU sleeper app
[Samsung Galaxy Nexus] pdxtechdoctor:
People, please post your Gnex model with your stats..

Part or the problem here is the fact that nobody says if they have a GSM or LTE Gnex.. the LTE units does use quite a bit more juice than the GSM ones.

Personally I would love to see some battery stats from people on Verizion or Sprint(with active LTE) with LTE on and with LTE off..

For the sprint people, do you have LTE active in your area? if you do not and you have LTE turned on, I'm sure that would be a huge battery hog...

To the juice defender post.. Turn of you radio? really? this is a phone... in order to receive phone calls the radio must be on.. I can't speak about the CDMA version, but my GSM uses at most 5% cell idle time after a full day..

This GSM Gnex actually has the best battery life out of anything I've owned and I've had a few smartphones over the years

Some interesting ideas in here. Will certainly try out a few. I have a GSM version and in general I can get more that 24 hours. I am however not a heavy user.

I also use Franco kernels(348 only) and personally I found it to be an improvement to stock.
[Samsung Galaxy Nexus] mmead1143:
QFT - JD increased my battery life from an average of 8 hours of usage to 15 - I'm not listing the details of my settings,rom,kernel as nobody's phones/settings are alike.

---------- Post added at 01:45 PM ---------- Previous post was at 01:41 PM ----------

Let me add that JB simply turns everything off when you aren't using it - sync settings are set so you cycle everything as often as you like but each app is controlled so you aren't firing off syncs all the time.

For me this is a big battery saver as I receive 300 email per day for business - so if I'm syncing all hte time the battery drain is insane.

When I wake the phone, everything is firing like normal.
[Samsung Galaxy Nexus] wissamidrissi:
so useful information, thank you very much :D
[Samsung Galaxy Nexus] mikegodzwa:
All about the network signal

I've played around with kernels and underclocking on my Sprint GNex for the last year with no noticeable improvements over stock. The big battery drain for me comes from Sprint's poor signal quality. I can get 12-15 hours easy on WiFi, but when I'm out and about I'm lucky to get 8.

Accidently hit thanks.... will these be compatible? I'm sure they had to make framework edits to make this compatible... don't know if those will overwrite any changes (if there are any) to this rom... I would hold off on those until xbtx or xboxfanj pipes in here...

Edit- should've looked through the op a little more... looks like the skins are just changing some pngs... should be good to go! Back up first just in case!!!
[Epic 4G Android Development] xBTx:
Regular .apk themes should work just fine, as long as they're for 2.1 (but why would you want to change the theme? Warm is so sexy). Unless you're decompiling and modifying the framework.jar that came with this ROM, stay away from framework. In fact, I wouldn't recommend framework mods at all. This ROM tends to be pretty volatile.
