Everyones different..........my setup with stock 1750mah battery if I drained it to 1% would get 5 hours and 50 minutes of screen time. Extended battery would probably add 40 minutes to that.

It's around 15% increase with the 2000mah

---------- Post added at 03:03 PM ---------- Previous post was at 03:02 PM ----------

It's not much different for me when i'm off wi-fi, around the same maybe a little worse.
[Samsung Galaxy Nexus] opethrocks:
When manually undervolting is it recommended to disable smart reflex? Since it undervolts automatically?
[Samsung Galaxy Nexus] dwang:
I can get over 5 hours screen on time w wifi on, but only about 4 hours using 3g on my gsm gn w the 2000mah extended battery.
[Samsung Galaxy Nexus] pewpewbangbang:
I don't think so. I think manually undervolting with smart reflex basically sets an upper ceiling for the voltage. So smart reflex will never go above the ones you set. I may be wrong, but thats what I think happens as changing the voltages definitely does something, try lowering your max speed voltage and it will reboot if too low.
[Samsung Galaxy Nexus] BrUhNiGGs:
I have no experience with manually undervolting. Do you basically just lower numbers of each frequency to the level in which where your phone can be stable and handle at the same time? I always use SmartReflex to do it for me but now I decided to change UV values myself to see if I can achieve even better battery life on my LTE Nexus.
[Samsung Galaxy Nexus] clepsy:
Well, it's not a big improvement over the stock battery, but I found a better feeling in my hand with the extended battery, and yea a few minutes or 1 hour of screen time more

Maybe I'll do the same next day with the stock battery, same setup
[Samsung Galaxy Nexus] nikulogical:
Is 2% drain per hour while in sleep with generic hot plug normal or bad?
[Samsung Galaxy Nexus] pewpewbangbang:
That's reasonable I think. I see tests where they say like .3% an hour......i personally think I get around like 1% an hour or less on standby.
[Samsung Galaxy Nexus] CaspaTheGhost:
OK, today's full use on the latter setup and there's an improvement in both performance and battery life.

My battery has an awesome drain last night while I was sleeping on 135. This may be my m3
[Samsung Galaxy Nexus] willl03:
50% brightness and LTE cant help.

After 25h off the charger and 2h screen on time I'm at 40% battery right now. Make sure your phone sleeps well. A black themed rom + gapps helps the battery quite a bit

My setup is:

GSM

Stock battery

BlackICE rom 31.31

Franco 135 512mhz gpu

384-1344mhz

Hotplug gov

Aggressive UV

Full sync

No wifi

Auto brightness

I froze all unneeded apps and services in Titanium backup, charged my battery to 100% and deleted the battery stats after flashing this setup, maybe it helps.

Few weeks ago I was too wondering how people reach 3h screen on time and now I'm there big time. You have to find what works the best for you, good luck!
[Samsung Galaxy Nexus] asim0:
@neotekz

how do you manage to stay away from your phone for so long ? I only manage to do that for an hour or so maximum...

What are your settings for getting a life?

just kidding :D it's just that when i see people posting 5hrs screen on time and it's not the weekend, i find it a lot of time watching your smartphone on a work day:cool:

(of course some people use their smartphone for work, of course...)

[Samsung Galaxy Nexus] samizad:
One observation I have made on battery life is that at a charge of 98% and over, things are strange. The phone sometimes charges itself even when unplugged for 10 minutes. I've had my phone go from 98% to 100% all by itself!!! A battery graph showing a flat 100% for 6 hours looks pretty amazing but you have to take this stuff into consideration. I think the battery indication is only accurate in a range of 15% to 95%. Just to clarify, this is not a complaint about kernel or ROM. It's just an observation.

On the subject of Generic Hotplug and battery drain in deep sleep, I was having problems in 132 and CM9 but since last night, I have been testing the Generic Hotplug with 135 and AOKP B31. Overnight, I had a drain of -6mA per hour with data and wifi on. This is pretty amazing.
[Samsung Galaxy Nexus] pewpewbangbang:
Very true, i've charged at 100% but the battery graph raises a little after unplugged over time ever so slightly, then goes back down to 99% etc...thats why display time is one of the best ways to judge battery life in conjunction with the standby time.
[Samsung Galaxy Nexus] chlehqls:
Wow, much better performance than the last time I tried it. It seems even smoother than faux's 15m in terms of gaming.

I consistently got 4 and half hour of screen on time after I hit around 20% with faux's + AOKP b31. Let's see if it does even better.
[Samsung Galaxy Nexus] spinkick:
Does the 500mhz video card overclock use more power than 384?

I mean, enough to make a difference
[Samsung Galaxy Nexus] mrfrag1337:
AOKP + Franco Kernel is incredible for me.

384-1344

OnDemand gov

Hotplug On

Brightness 25%-50%

cpu undervolted

I think is the best battery and perfomance kernel. I came from cm9 and the rom could help too. Dunno...
[Samsung Galaxy Nexus] samizad:
No. It doesn't make a noticeable difference. If your phone can handle the 512MHz GPU clock then you may as well flash that one.

I've managed to get to the limits of the GNexus IVA and CORE related.

When you reachs de limits you hear a *crack* on the sound when modifuing the IVA selector and reboots when undervolting too much de CORE. (I'm at @384 GPU OC)

This are my limitative one's:

I'll test today battery life :)
[Samsung Galaxy Nexus] nikulogical:
I got about 11hours total and 4:15 hours screen on with r135 interactive 700/1350, generic hot plug, wifi. Best so far for me.
[Samsung Galaxy Nexus] monkey hung:
I'm getting massive battery drains with 133 and 135 on AOKP B31. No matter what setting I put, the kernels are just draining my battery like crazy. 130 was much better and lasted longer and I at least reached 5 hour screen times. It's difficult now to get at least 3 and a half hours screen time with the latest kernel and I reached 11 hours of battery life.
[Samsung Galaxy Nexus] mazubo:
Have you checked for any rogue apps running in the back ground? Any wake locks via CPU spy? Have you used better battery stats from the market?

I had some small issues prior to learning about these apps/techniques......

I hope these help :)

:-D
[Samsung Galaxy Nexus] samizad:
Only 11 hours? What are your wakelocks like? In idle mode, I am getting 98% deep sleep.

Have you tried wiping and re-flashing AOKP Build 31?
[Samsung Galaxy Nexus] monkey hung:
It seems really fishy, I know. I'm going to full on wipe everything and install AOKP B32
[Samsung Galaxy Nexus] nklenchik:
AOKP isn't known for the best battery life to be honest. Why not just jump to Liquid with pretty much the same features?
[Samsung Galaxy Nexus] neotekz:
what voodoo mods are you talking about? did supercurio release a screen mod for the galaxy nexus?
[Samsung Galaxy Nexus] nikosrs4:
Does everyone that have great deep sleep drain use hotplug? I dont use it and in 133 and 135 I have about 1%/h loss with nothing changed to my apps and no wakelocks. I will try with hotplug to see how it goes.

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] samizad:
I stopped using generic hotplug in CM9 and idle battery drain improved a lot. Now, I am using AOKP B31 with hotplug and things are even better. I am starting to think that it depends on the ROM and the importance of wiping all before flashing a ROM.
[Samsung Galaxy Nexus] Bisazz:
Can you try playing back a video? Even just a video from the phone's camera?

I found I was able to get that low and listen to music for hours upon hours with no problems, then the instant I tried to play a video, it couldn't be played with the stock player, and in MX player it froze and any sounds made from that point onward were loud static.

I found that happened whenever I undervolted the IVA more than -25mv.

OC'ing useless? I would have thought its a sure fire way to pump up performance... 1.4 is too troublesome for most as you'll know from your early releases but I hear 1.35 is way more GN friendly... Up to you obviously mate. Consider it my Xmas present? ;)

Also if this battery keeps up it'll be boxing day when it dies! Thanks again mate
[Samsung Galaxy Nexus] GchildT:
How did a 4.03 ROM ruin your phone?
[Samsung Galaxy Nexus] GchildT:
I was using the OC'd version of this kennel when it was 4.01 based. It worked perfectly for me. But, he is right. Performance gains are not huge. AnTuTu numbers were the same OC'd or not. Of course quadrant had different results, a 400 to 500 point jump in the score. But, which one do you trust? Anyways, the OC was perfectly stable for me. Others had mixed results.
[Samsung Galaxy Nexus] GchildT:
Yeah, it's pretty good. I tweaked mine a bit. It was a good base rom though!
[Samsung Galaxy Nexus] franciscofranco:
I still have to think about the OC... I don't want my kernel to be like the others, it's unique, and adding OC it just feels like...another one...and this is already tweaked so much that I don't see why I should add an extra step. Like I said, I gotta think.

About the battery I want you people to test this: Reboot your phone, then after it booted up open up Camera, then close it. I think we have the same bug as we had on the NS. Google Talk Video version opens the camera during boot and its sensor gets fired up and since the camera isn't closed the sensor just stays there open in the background wasting battery like there was no tomorrow. Opening and closing the Camera after booting up closes the sensor and then the GN enters in Sleep mode just fine (easy to check with Cpu Spy). If more people can confirm my initial testing then we may "have" found one of the possible battery drains when the phone is idle.

I just got mine (for some odd reason), and I'm flashing the kernel as I'm typing.
[Samsung Galaxy Nexus] ztm.000:
So, after flashing and re-flashing different things, it's the kernel that is disabling Google sync services (blue bars). Guess I'm gonna head back to stock. Bummed.
[Samsung Galaxy Nexus] franciscofranco:
That doesn't help at all. How in hell can my kernel be ****ing with Google stuff?
[Samsung Galaxy Nexus] energie:
Franco you are right about the google talk, video bug. :/

Still wake the phone
[Samsung Galaxy Nexus] ztm.000:
I don't know but it sucks.

I'll wipe data/factory reset

I'll wipe dalvik

I'll flash the 4.0.3 ROM + Gapps and I'll boot and have Google sync just fine.

Then I'll reboot to recovery to flash your kernel and the bars remain gray afterwards.

And I'm bummed because your kernel is such a beast.
[Samsung Galaxy Nexus] GchildT:
Lol. I don't really think you can blame sync problems on a kernel.
[Samsung Galaxy Nexus] ztm.000:
You'd think that but I've flashed two other kernels and all is well. So why wouldn't you blame it on the only thing that's affecting it. I'm not saying it's the kernel, I'm just saying that it could possible have an effect.
[Samsung Galaxy Nexus] franciscofranco:
As I thought. There is no other workaround as either uninstall Google Talk or open/close camera after boot manually.

It's not that I don't believe you, but I need logs, proof etc. Without that there is nothing I can do as I can't reproduce that **** because my data works fine. Are you using the latest baseband?
[Samsung Galaxy Nexus] ztm.000:
The latest would be XXKK6 correct? I'll flash it again later on and give you the logs. What method would you like me to use in retrieving the logs?

What do you think? The saved values are the values you entered earlier and that are saved in the SharedPreferences of the app. The current values...are...self explanatory.
[Samsung Galaxy Nexus] clepsy:
Is there any reason that we only have 2 voltage steps for IVA allowed for modification via app? as I see 4 in sys/class/misc/customvoltage :)

Also the CORE voltage, I can get to 1100mv for 512 mhz without any problem, didn't try lower but I remember that I had problems with one release which have lower voltage set, anyone faced this situation?

Later edit:

Ok now just try to lower the voltage for a lowest frequency and at some point I got a nice colored flashing screen :) fixed with a reboot

Guys what's default 384 or 512 mhz for GPU?
[Samsung Galaxy Nexus] samizad:
Razer, you're the man. I follow your theme on GS2. I hope this is not a wind-up. This kernel comes with two versions 384 and 512 for the GPU. You can download either version although some people's phone can't handle the 512. That's why Francisco also makes the 384 version available.
[Samsung Galaxy Nexus] Razer(x):
Thanks man ;)

So default voltage is 384 and 512 is overclock right?
[Samsung Galaxy Nexus] SkaDiZ:
Hi, how do you check for this kind of crash log?
[Samsung Galaxy Nexus] samizad:
Actually the default clock is 317 MHz. So technically, both 384 and 512 are overclocked.
[Samsung Galaxy Nexus] jnr21:
Actually 384mhz is default but it's underclocked to 308mhz (default kernel).
[Samsung Galaxy Nexus] Razer(x):
Sounds weird to me, because i've read this is the best kernel for battery life. I'll test and see :)

EDIT:

@jnr21, now that makes sense.
[Samsung Galaxy Nexus] samizad:
Good point. The default GPU clock is 384 but Samsung ship the phone with GPU underclocked to 308 MHz because, apparently, there is no great speed gain but there is a battery loss. Whether right or wrong, this issue is the subject of other threads.

I don't know where I got 317 from. Momentary confusion.
[Samsung Galaxy Nexus] raubkatze:

[Samsung Galaxy Nexus] eRajesh:
Will not it be better to add the 380MHz GPU clock speed to the 512MHz kernel?

Right now, the GPU frequencies are 153MHz, 307Mhz and 512MHz. How about adding a 4th frequency 380MHz between 307MHz and 512 step?

Also, can someone tell me the voltage used by the GPU at 380MHz and 512MHz respectively?

Lastly, what do you guys prefer? Manual UV or let Smart Reflex do its job?

If you guys UV, can you tell me your UV settings? Looking for a starting point here.
[Samsung Galaxy Nexus] franciscofranco:
I will explain it when Im back home.

Aye I can increase the throttle limit, stock values are a little low.

I will explain that later when I get home.
[Samsung Galaxy Nexus] relax24:
In all honesty, I don't know if what I'm doing is correct, but I just turned off smartreflex, and undervolted using the voltage smartreflex was setting as I monitored it:
