4.1.2 improved battery life - Samsung Galaxy Nexus

After receiving the 4.1.2 OTA update, I'm getting a much better battery life.
It used to be dead at the end of the day. Now, I finish my day and the battrey is on 45% with the same phone use.
I also find that apps and mostly google apps do launch faster
Have you also noticed it?

CM10 "added" 4.1.2 into the compilation recently & I've noticed a difference too... :victory:

Can you give us some screenshots of the screen time?

Only with data all the day i got 3.30h and 19h on, automatic brightness, sync on. Google stock 4.1.2

4.1.2 appears to have a big affect on battery life. I've gone from needing a charge after about 12 hours to going all day with charge left

When 4.1.1 was released, people reported that Google Now was a battery hog. Maybe Google improved it drastically.
Those who experience better battery life with 4.1.2, do you have Google Now activated?

To add on to this. I'm noticing FAR fewer wakeups (alarms) caused by Maps services on 4.1.2. That has an impact regardless of whether or not Google Now is running.
They definitely made some changes to location based services considering the menus were modified and additional settings were added.

Using a custom ROM and kernel so I can't answer this. But my battery life using CM10 + Franco Kernel has definitely improved.

I logged in hoping someone had made a topic about this. On 4.1.1 I did not use Google Now because of the effect on battery life it caused. I tried it on 4.1.2 hoping it had improved. In my opinion it did. Still need more days to test but it seems way better now. Even saying that, I still feel it takes too much of a hit on battery for me to continue using it.
Just my 2 cents.

Umm, it absolutely wouldn't be better at all.
Rooting and using custom ROMs have it benefits and my battery life wouldn't be to where it is now (at least not as long) if i was on stock.
Stock is too boring for me. I need my lock screen customizations and backups

It doesn't take away root capabilities right?

I use it while traveling. A lot of the functions are designed to help you familiarize yourself with the area.

The 4.1.2 custom ROMs have done me better overall than the 4.1.1 ROMs.

I haven't noticed much of any difference one way or another.

So the latest cm10 nightlies contain 4.1.2??
It seems the battery life claims are pretty circumstantial. I wish there was a standardized test for this..
Sent from my Galaxy Nexus using xda premium

Cm10 nightlies are cm10.
And battery is much much better.

I never let any Rom to settle down(for more than 2 days) to comment on battery life, but i hope the thread is pointing to facts
So now in Stock will report back after 2 charge cycles at least

The map process is eating my battery to. I reserve testet it yesterday (nandroid of 4.1.1 back) no problem and then again OTA to 4.1.2. Anyone out there a possible resolution ? Had 2-3 days with my battery, now maybe one day.

If you use some sort of Recovery like CWM it does not. CWM will ask you if you want keep recovery and/or root.

Ics or jellybean

Which is more stable in term of battery and speed. I just feel that jellybean has more features and ice cream sandwich is more stable. So I'm undecided
Sent from my SPH-D710 using xda app-developers app
As of right now I would go with cm9 beta 1 because it is extremely stable compared to the jb roms and it has pretty good battery
Sent from my SPH-D710 using xda app-developers app
Ics of course. There is no source released yet for JB. Read through the threads to see what people are experiencing on the browser you are interested in. It might be that the issues that people have with jelly bean you don't care about or can deal with.

I just want a really good battery rom.... I'm sick of touchwiz. But I'm guessing they have the best battery life?
Sent from my SPH-D710 using xda app-developers app
Supposedly. There is a lot you can do to effect your battery life. I get excellent battery on cm9 beta 1 which is aosp. Who's know how the people who complain about battery life use their phones or what they have synced or if they use proper install instructions. I never had battery issues on the ff18 or fh13 otas either. So I'm not sure how much you can count on people. I did a factory reset and wiped cache after updating on the otas. And I make sure I do exactly as the OP says to do when installing a rom. If you do flash something go through the thread to see how people help with battery life like un syncing stuff you don't use etc. Also give the rom a few days to settle before freaking out and reverting to something else. You can always really tweak with stuff and under clock and what not'

I was wanting to know which ROM has the best battery life on the Gnex the CDMA version.

They are all pretty much the same IMO. The screen sucks up juice so keep it off as often as possible lol

If you want the latest software, most stable, and best battery life ROM, go with MMuzzy's AOSP ROM. Using it now, and its amazing
Sent from my Galaxy Nexus using xda premium
ROMs themselves rarely ever have an actual impact on battery life. Most postive effects for battery come from the kernel, and negative ones from rogue apps.
Before you ask which kernel offers the best battery, it really depends on the requirements of the user and the phone itself. You'll just have to try a few.

How do I switch out the kernel. I'm kind of a noob at this stuff...
Sent from my Galaxy Nexus using xda app-developers app
Flash it like you would a ROM. Make sure you find one that is for the version of android your ROM is based on. I would suggest tying Franco kernel, but there are many good ones.

FYI....this thread goes in general.
Flash kernel in cwm the same as you would have a rom. Be sure to clear cache/dalvik first.
For the moment the ROM with the best battery life is SlimRoms 2.7

I've tried many ROMs and Kernels with no success in the battery life department.
My phone charger died so I downloaded an app...Easy Battery Saver...my phone was still at 34% after 1 day and 7 hours. I was NOT heavily using my phone but still this is the best battery life I have ever experienced. I was always on the "battery saver apps are useless" team until recently.
Don't get me wrong, I'm still flashing
Just love my new app.
i tried miui, pa, vicious, aopk, smooth, and now using cm10. tried out different kernals too,but at the end, all the roms cant pass 1hr 50mins of screen time.

Hmm.. thats strange. I'm on MMuzzy's ROM which is pure AOSP and I get around 2 and a half hours of screen time. And some people around the forums have gotten around 5 hours of screen time with different combinations of ROMS and Kernels.
I have tried numerous roms, if not all of them for the galaxy nexus, and there is a difference between roms, even using the same kernel.
I have been getting amazing battery life using Eclipse.

The mods can move this thread, but in the mean time, it is a good question.
I used to get some awesome battery life. VZW + 2100mah. Typically 4 hours screen on time was normal.... now I'm lucky to get 1hr. I can't remember if it was the jelly bean update or the inclusion of Google Now.
Does letting the ROM settle really help? I have been getting terrible battery life out of my 2100mah. The battery just drains when the screen is off. No rogue apps, but this is a fresh install as of 24 hours ago

I believe use what you like as long as you use Lean Kernel you should get good battery life.

I wasn't going to put my 2 cents in but because there are so many complaints about this being in the wrong place, I just have to now.
I have tried many different ROM's and kernels and found there always seems to be the "right" combination sooner or later. Right now I am on AOKP w/Franco M6 and getting about 14 hours with 24% battery left, 2.5 hours screen time, mostly LTE and moderate phone use, best I have seen of any combo for me on this ROM. For CNA the right kernel for me was lean kernel. A little experimentation and patience and you will find that sweet spot soon enough.
Edit: the whining drew me to it, sucked me in so I couldn't stop myself from answering
If someone can get 4+ hours screen with mostly 3G, let me know. haha.
Wrong section
However as for battery life slim ROMs work great but I'm on jbsourcery built in trinity and I've definitely had worse d: the only ROM I've used that's had has battery is pa however they've had multiple updates since then so I'm sure its not horrible now

2) If you guys see something posted in the wrong section, report it. No need to get in an internet gang war about it. Us mods have a life too and we can not be here 24 hrs a day to watch over you. When you hit the report button, we see it.

Ics battery vs Jelly bean

It seems like to me, I get better battery with Ics than I do with Jelly bean. I'm also stock, non rooted.. What do yall think?

Mine feels about the same.. All depends on the day. And due to jb being much quicker you automatically tend to do more tasks which means more screen on and system usage than ics which Is understandable
ICS and JB battery seem the same to me, but I am always playing around with my phone so I use a lot of juice during the day.
Will that affect Google now?

I have to agree with you. Since I've updated, my battery drains a lot quicker under normal use.
After sprint's jb update my battery doesn't really last as much as it used to, i stream music from pandora all day at work and jump on some games at lunch by the time i get home i used to still have about 50 to 60 % and then i would continue to use netflix, games, some web browsing and what not, now i have to charge my phone at work after a few hours of listening to pandora and then again towards the end of the day, jb is nice but considering the poor battery life i think i'll stick to ICS until 4.1.2 comes out, i've heard it has some battery life improvements (at least on the nexus).

Maybe you guys need to dabble into custom ROMS perhaps..
I'm on Team Sonic's FreeGS3 JB ROM (and before that was on their ICS ROM) and my battery life is better than when on ICS. It is that noticeable.
I'm gonna give that rom a try, i've just been lazy to install windows to run odin but i'll eventually get to it, on the other hand i disabled stuff from google now and maps and it seemed to help

Get Most Battery Life Out Of Your GS2

I have lately been running tests of different ROMs and trying to get the best battery life possible! I have tested out these ROMs:
Jedi Mind Trick X1
CM10 Stable Release 4.1.2
AOKP Jellybean 4.1.2
Slim Bean Unofficial 4.1.2
When i flashed these ROMs i did a battery calibration (off app from play store NOT CWM). And ran them on FULL Brightness, GPS ON, BLUETOOTH ON, and running on Wi-Fi! I opened up netflix and watched multiple movies (same movies for each ROM)...until the phone went completely dead. Here are the results i got:
Jedi Mind Trick X1: 4 1/2 Hours
CM10 Stable Release: 3 3/4 Hours
AOKP Jellybean: 4 Hours
Slim Bean Unofficial: 5 3/4 Hours
As most people know the Screen does use over half of the battery. So on this test the screen was on NON-STOP for the amount of time you see above. And 99% of people will not have their screens on for that long at one time. So this is the WORSE-CASE scenario for battery life. I was impressed mainly with Slim Bean and Jedi Mind Trick did good as well.
You may get different results than I did. If you are using a ROM that i did not test or you tested one of these ROMs above and got different results please post below your results.
I hope this helped guys
Thanks for this.... maybe i need to try out slimrom again

Ok guys. I have officially moved over to the Galaxy Note 2. I no longer have the Galaxy S2 so i cannot add anymore support for it since it is against the rules. I appreciate all the help from this device thread and now you guys can see me at the GN2 forums. Goodbye Galaxy S2 Users
Personally I have the best battery performance, regardless of the ROM, by setting up CPU profiles. Basically you can set one profile to limit the to 432 (or whatever you want) while the screen is off and 1500+ while screen is on. I use ROM Toolbox Pro for this and get really good results. If your interested just do some searching on ROM Toolbox Pro and CPU profiles. Just thought I would share

i believe you easily!
almost same config (rom), with leankernel and 4.1.2 version is doing the job with battery life, compared to 4.2 JB, its day and night.
Ill try trinity, already placed it on my memory but was testing leankernel
No SOD, or heavy drain in use ?
I'm trying the new dummy kernel from ak and it works really good. You should give it a try.
Dummy kernel and Purity rom does the job. 36 hours or so of usage with 3hr 30min of screen time or so. 3G on throughout. ARHD does the job too
I recommend AOKP with lean kernel. Best battery saving and buttery smooth.
The combo is so stable and it's my daily rom.

Given that you have to find *your* best combo, I think that Purity with lastest franco.kernel is better for battery life, even if AK kernel is a little better for performance.

GSM and LTE have different phone/data HW and chipset just because the phone technology is different. You have to find you custom (or stock) rom in your own forum.
And yes, you are quite OT , but I'm not an admin
Yeah sorry for the OT question. Also I wasn't asking about custom ROMs, I was asking about kernels but thank you I appreciate the reply.

I've tried about all of them and aosp with stock is definitely the best battery life........ With my usage pattern. Your mileage will probably vary.
