[Q] Best Battery kernel Rom? CDMA Galaxy Nexus

Hi,
Just coming from my galaxy s epic 4g touch which was pretty good on battery.. I know roms and kernels could fix that issue with the galaxy nexus cdma which isn't so good..
Which of you tested out a few kernels/Roms and found great battery life when putting the galaxy through it's paces?
I actually love love the phone but the darn battery kinna sucks

Welcome . I also left Sprint and the E4GT. I love this Nexus. The 720p display is so awesome. And official ICS is a major upgrade for the Android OS.
But sadly the battery life is nowhere near what I was running with Calk's ROM + ICS theme. I could go 40 hours easily on light use. And get 12 - 14 hours on heavy days with tons of use, 5 hours display time.
I put the Nexus in the middle for battery life. My old but awesome EVO 4G sucked battery life like a vampire. With heavy use maybe 5-6 hours and light use was maybe almost a full day.
The Nexus seems to be in the middle, for sure way better than the EVO 4G, but not as good as the Galaxy SII, for battery life.
I think with ICS being so fresh, and the Nexus GPU new too, it will take a few Google updates and revised ROM's to really extend battery life close to the SII.

Get the extended battery, can maybe add 2 hours extra life. Turn off LTE if you don't need it, 4G sucks battery pretty good.
As far as ROM's + kernels, there are some really good ones out there.
- Android Revolution HD
- AOKP + Franco kernel
- Operation Code Name
Many others.

Ive tried aokp w/ stock, francos, imo
to be honest, i have not tested the IMOs fully, as an update was just released and i decided to flash with jakebites mod.
I am not a battery stats crazy guy, but i can say that both francos and imo are great so far, improvement in speed and battery life over stock.
I've heard people are getting great battery life with trinity's new kernel and if you are looking for stability, i hear its on heyitslou's defiant
I've found this list to be the most complete.

I would like to hear your feedback on your experiences also, as there are just simply not enough hours in the day to try everything, just want to try the best. hope that helps...

[Q][kernal] What's a good one?

I have stock rooted, I love the phone and didn't want to flash a ROM so soon but I was wondering, what's a good kernal thats better than stock, that increases battery while not affecting the speed negatively, I currently get about 10-12hrs on my battery as is
Search doesn't work that well for me on mobile, so sorry if previously asked although I did scan the threads but just wanted to see how you guys are doing with your current kernals

Try tdj's dark side kernel. Very smooth and great battery life. Plus you can overclock and under volt.

i think there's only about 4-5 options out there... but each phone's hardware is different so each kernel will be different.
For example, my phone works really well with faux and darkside, but i get quite a bit of drain from eugene's kernel (yes I do configure my clock speed and voltages) people say synergy has great battery life and is smooth, however, my phone says different. it lagged more than the 3 mentioned and battery life was equivalent. There is also the bullet kernel... i haven't played with that... not sure if im missing any other kernels... but yeah i suggest giving the first three a try first as they are currently being supported.
reminder, you should let your phone go through at least 2 charges before comparing kernel's battery life etc... and with our phone.. thats 2 days lol

Pretty much any of the kernels on the first page will give you better than stock battery life. Faux, synergy and the dark side kernel are the three most popular kernels amongst Devs so that must mean something.

To be honest, i only ran stock for a few hours. Ive been running a custom rom since day 1. But I believe it would be better then stock because TDJ has undervolted the kernel slightly.

I'm using the darkside right now and so far so good
Swyped from my Sgs2 T989

I've tried most of the popular kernels and the best battery life I've observed has been with Synergy... hands down gives me the best standby battery life.
But what I've noticed that gives me even better battery life is just turning off mobile data when I don't need it (in class, during meetings)... which also turns off the background syncing.
But in the end, it's all up to you how crazy you want to get with your battery management.

Stability of CM10?

I'm currently looking for a ROM base to modify to my needs. I really like the features available in cm but I'm not sure if cm10 (stock) is stable enough for production use yet. Does anyone have experience with this?

Been using it for about a month now and have no issues what so ever, I recommend the builds by Euroskank as he adds some really useful features.

I threw CM10 on mine and I had some radio issues. I don't know the technical details but the signal wouldn't lock in completely. The signal notification on the top bar would never turn blue no matter how perfect signal was, the wifi wouldn't lock in blue either. Reverted to stock for now.
Other than that it was awesome!

FYI - even though your bars are gray, you still have an active data connection. When they turn blue it means they are connected to googles servers

Sorry for OT - but try JBSourcery instead. :good:

I just got my Verizon GNex about 3 days ago and right when I got it I rooted and put the CM10 preview ROM on it. I haven't found one thing wrong with it yet. Works great for me

You can also try Paranoid Android which has CM10 as its base and this ROM has been very stable for me. This ROM can be used in stock phone layout, phablet, or tablet modes.

How is your battery life? GPS? Still no bugs?
I'm still running Pete's Bugless Beast and its so perfect but just no mods or customization. I want to be able to customize but I don't know that I want to risk losing my bugless JB...

Has anyone compiled cm10 from source with no customizations other than the camera, NFC, and GPS files? How is that build? I'm going to be modifying it for personal and perhaps submit back.

GPS is perfect. Locks immediately. Battery life is nothing to write home about. I have the official extended battery and with decent use I might get 8hrs if I'm lucky. I'm up for ideas on other JB ROMs for Verizon that have better battery life.
Everything is perfect except for the battery. Almost afraid to flash another ROM because everything on the CM10 preview works for me.

I've been using XenonHD ROM for about a month now and find there are many features that were present in CM9! Runs fast and smooth!

JTFC, that's awful. How does it compare with what you had on ICS? I get decent battery life on JB (CM10), but still slightly lower (10-15%) than on CM9, but 1.5 to 2 days is still possible with my use + 3 hours screen on or so over that time. This holds true for all the JB ROMs I've run. 4-5 hours of screen on time over a workday of hard use is still possible for me, but idle drain seems to be hit/miss, some nights 0.25%/hour, other's 1%. Sync seems to be a more of a battery eater on JB, and I haven't bothered running Google Now since the first day or two I ran JB.
Shall see how today's JRO03L build performs.

Running vicious rom, the cm10, great with Franco kernel and his app. No complaints. Only thing is i can't get play music to download to my phone from the cloud

Unfortunately I don't have anything to compare it to. The GNex was a warranty replacement for my old Thunderbolt. After I got the GNex I immediately rooted and threw the first JB ROM on it I could find. I will keep searching through various threads in the development forum and see what I can come up with.
Oh and thanks for confirming my suspicion that my battery life is below average. The weekend is here. Plenty of time for experimenting

I highly recommend Better Battery Stats if you don't have it already. There's a free XDA version posted on the site, but the Market version is well worth the ~3$ also. Sync and location services (GPS or Google) and Google Now seem to be the biggest offenders on JB. I run sync and location sparingly.
That said, the GN is definitely no battery queen unfortunately :crying:

[Q] Is the Epic what I really want?

Looking for a capable Android phone for my mom. She has no experience with any kind of smartphone. But she knows for sure that she wants a slide-out keyboard. Our other requirement is that the phone work on Page Plus (Verizon network). I'm well capable of getting the Epic 4G working with Page Plus. Since we're using Page Plus, there's no contract, hence no carrier subsidy... which is what brings me to the Epic 4G.
The price is nice-- obviously much nicer than any newer phone. My only concern is that the phone may be antiquated, and might not be up to the task of modern apps. I don't expect much, though it's gotta be able to at least run Angry Birds without stuttering (I feel this is a reasonable place to set the bar).
Would anyone care to speak to the phone's performance, and whether this phone will suffice for another year under today's newer apps?
Thanks!
FYI, I plan to root and install CM7, based on what I've read here regarding performance and battery life.

I still think of the Epic as one of the greatest phones to date. With the requirements you specified it should suit your Mom's needs. You can even drop a little overclocking on that CM7 to give her that extra burst of speed to handle those nasty birds..lol.

Thanks Kenny. BTW, I've noticed that CM9 has been pretty stable for a while, and that CM9.1 has even been released. I wouldn't be ready to dive into CM10 just yet, as that's still on nightlies. But in your opinion, do you think CM9.1 is up to snuff with CM7 in terms of performance and battery life?

I think it is definitely there in stability but I don't think anything beats CM7 in battery life setting for setting. Next would be the TW GB ROMs and then CM9 for battery life..imho.

Your humble opinion is much appreciated. In general, does CM7/GB have better battery life than CM9/ICS, or is the difference in battery life specific to the Epic ROMs?

i got some of my best battery life on CM9 about 19 hours with 2 hour onscreen time all push notifications off , i'd recommend getting a epic 4g touch battery for her the extra 300mAh makes all the difference on the ride home from work

Yes on the Epic, in my experience because CM9, ICS and JB are meant for phones with 1GB of RAM and is tough on resources. If you use a GB ROM the same as a CM9 or higher ROM with notifications and syncs on, GB will get better battery life everytime. I would get 4 Hours screen on time with my Epic on The People's ROM and be about 30% when putting on charge at night.

For battery life CM7 ROCKS!!!!!!!!! CM9 not so much and I haven't tried 10 but 9 gives me issues so not even thinking of 10. I have CM7 on both mine and wife's phone and she couldn't be more happy.

Agreed again, though if you turn off data, it is a battery sipper, but that is not a best solution for everyone.
IMO, for the typical person that does not demand the bleeding edge, CM7 is the way to go. You get solid performance, great battery life, and all the benefits of a CM build.

[Q] Wholly Bleeding Battery Batman!

Hi!! I was just wondering which ROM has the best battery calibration so the battery will last longer! I know it is a powerful phone so it is expected to drain faster! Just need a good suggestion for the best ROM that will address this issue. ThAnKs!

This is a hard question to answer because battery life is very different from phone to phone but from what I've seen stock based roms like lifeless usually give the best battery life.

On Lifeless I was able to get full day usage regularly... CM10.2 8/20 build is also giving me good battery life
Sent from my LG-LS970 using xda app-developers app

I had good luck with Lifeless, but am really enjoying CM 10.2
I have underclocked to 1134 and my battery is quite good all things considered. I play Ingress for about 2 hours a day at full brightness with WiFi scanning constantly, and I have to recharge after about an hour of that. But everybody that plays Ingress knows how big a drain it is on battery. When I don't play, the battery is good for 10 hours + for me.

Better make sure you get the invite in order to play. It is, hands down... the... best... game... I have ever played on a mobile phone.

Ingress looks really fun and I started playing recently, but I don't have a plan with a carrier (I'm waiting for FreedomPop to come out). It's so hard to play on only wifi!

Where did you download the CM ROM? I looked on their site but the only model LGOG they list is the GSM model (Verizon, AT&T) and not the Sprint model. I loved the CM mod on my previous phones and wouldn't mind giving it a try on LGOG. Thanks in advanced for your help.
EDIT: NVM. I think I found it. I take it your using the "Unofficial" CM ROM which was ported over to the LS970? Had to do some digging over at the dev side but found the thread.

Installed the Unofficial CM 10.2 ROM latest version as of yesterday) and it works pretty damn good. Although battery life seems to be a little weak. But then again, I ran Eco Mode on the Stock ROM. Still, my phone sits in a security locker all day at work and not really being used and as of this moment (3PM EST) battery is at 61%. Whereas on Stock with Eco Mode it would be around +85%.
Not sure what is considered standard battery drain not using Eco Mode. However, that will drop sharply in an hour and a half when I get off work and start actively using it again. I'll be interested in seeing how long it will last. Normally I can go the rest of the evening up until bed time on Stock ROM without having to plug it back in until I go to bed. Somehow I don't think it's going to make it that far while running on the CM ROM.
